How to Safeguard the Most Vulnerable in Digital Healthcare

from AI algorithm to detect early cancer“Doctor in your pocket” Video consultation on smartphoneNext-generation healthcare technologies are being announced one after another at a rapid pace.

For example, as recently announced in the UK, users of the NHS app will now be able to collect medicines from pharmacies without having to visit a medical centre, and the usual paper slip given by a doctor will now be replaced by a barcode within the app. will be replaced by

Innovations like these have brought tremendous benefits to millions of patients. However, these benefits of digitalization are not evenly distributed. According to his Ofcom report in 2023: 1 in 13 households do not have access to the internet And a similar proportion do not have a computer at home. But even within connected households, the so-called ‘digital skills gap’ means many people may still struggle.

Imagine this typical case. Dorothy and Bill are retired factory workers in their mid-70s. They have their home computer connected to their TV and have a machine that allows them to (almost) send e-mails to their daughter who lives abroad.

It’s hard to use, but I love watching my family’s news come through the TV screen. However, I don’t use my computer much for other purposes because websites take a long time to load. Bill has a smartphone and receives photos of his grandchildren through an instant messenger app, but he doesn’t know how to send them back.

Prompted by a text message from their doctor, the couple confirms they have internet access and enters their email address. A few weeks later, I received a message inviting Bill for his annual checkup and treatment for shingles. However, subject lines are unclear and long messages are impersonal and difficult to understand.

The couple had only ever received emails from their daughter, so they thought the message from their doctor was spam and deleted it. As a result, Bill neglected medical checkups, ran out of blood pressure medication, and was left susceptible to shingles.

digital skills gap

The problem is that entry-level home computing is primarily designed for basic gaming and simple email exchange, and it’s not easy to interact with data-intensive web platforms or send high-resolution images of body parts. It is not intended for this purpose. The same goes for budget-level data bundles offered by mobile phone providers.

For people like Dorothy and Bill to navigate the digital health space, they need not only better technology, but also technical skills to interact with technology, such as comfortable typing, using a mouse, and navigating drop-down menus. Skills are also required.

Also important is “information literacy.” This is the ability to recognize when information is needed (such as an old address or login code) and how to provide it. Second, health literacy, or the ability to find, understand, and use health information and online health services.

Generally, individuals are either digitally equipped, technologically proficient, information literate, and health literate, or they simply are not. There is very little in between. And as A major analysis from the University of Oxford found that, the more indicators a person has of a disadvantage (low income, older age, preference for a language other than English, to name a few), the harder it is to access digital services. Several of these factors combine to make it even less likely that these disadvantaged patients will be able to connect to health services through digital means.

Unfortunately, such inequalities are nothing new. In fact, it was 53 years ago that British physician Julian Tudor Hart first proposed the Reverse Care Act, a principle that was developed to protect people who need health care the most: the poor, the less educated, It was argued that people (older people and people with frequent illnesses) are healthier. It is the least likely that you will receive it. There is no easy solution to the “digital reverse care” method. A person who lacks the necessary digital skills may be willing to go to the local library for computer training, but with an empty bucket he can safely “replenish” the complex skills he has missed. You shouldn’t think about it.

What is the solution?

What should NHS organizations do to ensure everyone gets a fair contract in today’s digital world?

First, digitally supported services should be designed or improved primarily for patients who have difficulty accessing them. A service that works for someone who is not familiar with or unable to use a computer or smartphone will almost certainly work for someone else. “Digital navigators” – human staff who can help patients find directions about services if needed – can be a big help here.

Second, healthcare providers need to look beyond the binary when assessing people’s digital connectivity and skills. Instead of asking patients if they have an internet connection, you should ask them to describe what they are actually comfortable doing with technology and customize their care package accordingly.

Third, for the most disadvantaged patients, those with complex health and social care needs, there is no need to use technology at all, especially when their needs are not adequately met by technology. Keep in mind that your approach may be the most appropriate. technology. For these patients, their records can be marked with electronic flags that remind busy staff to use no technology or provide a technology-free option.

And finally, we need to see digital exclusion first and foremost as a moral issue. NHS founder Nye Bevan said: “No society can legitimately be called civilized if the sick are denied medical assistance because of lack of means.”

Can naked mole rats hold the secret to their youthful appearance?

Learn from the mole rat

Feedback is promising a bonanza of new pharmaceutical, medical and lifestyle product launches that propose boosting hyaluronic acid levels for everyone. Hyaluronic acid is a substance recently found to provide some protection to naked mole rat cells from inflammation and early death.

Marketers who specialize in mass inflammation cannot afford to miss this situation. Journal of Experimental BiologyFeeling grateful for hyaluronic acid. Under the heading is “Anti-aging secrets from underground burrowing rodents” says the magazine. “Most cells live within a blanket of molecules and minerals called the extracellular matrix. In naked mole rats, this blanket is woven from a thicker fabric. Naked mole rats produce the heavier, larger molecule hyaluronic acid, which is the backbone of this extracellular matrix.

“This extra padding protects cells from inflammation and premature death, as shown by Andrei Seruanov and Vera Gorbunova's team at the University of Rochester in the US.”

The report ends with this almost poetic wink. “The fountain of youth may be embodied in the heavy hyaluronic acid of the naked mole rat, a nearly blind rodent with many wrinkles and yellowed teeth.”

encounter after death

After Mallard's gay necrophilia became known to the world 20 years ago, many more reports of “Davian behavior” entered the public record. A quick update here.

This topic received a lot of attention in 2003 when Dutch ornithologist Keith Moeliker won an award. Ig Nobel Prize His now famous paper “The First Case of Homosexual Necrophilia in Mallard Ducks” Anas Platyrhynchus”. Mr. Mauliker talked about two ducks that encountered the Davian bird. The necrotic behavior is called “Davian” here because American ornithologist Robert W. Dickman published a paper in 1960. This is because he gave the necrotic act a new name: “Davian.''Ground squirrel's “Davian behavioral complex”” was published. mammal journal.

Michal Řeřicha and his colleagues at the Czech University of Life Sciences in Prague have published a report documenting a practice among ladybugs (known in some areas as ladybugs). The title of the report is scary.Mating of nonnative ladybirds with dead conspecifics is influenced by sexual fasting in males and time since death in females”.

This comes just three years after a report on necrophilia at sea by Amber Lee D. Kincaid and colleagues at the Mote Marine Institute in Florida:Necrosis of a bottlenose dolphin (Tursiops truncatus) near Sarasota, Florida.”.

High-profile, hard-hitting reports sometimes take a literary turn, like a 2015 paper about South American snakes.The sexual appeal of corpse brides: unusual mating behavior of Helicops carinicaudus (Dipsadidae)”, by Raíssa Siqueira and colleagues at the University of São Paulo, Brazil. They write: “We observed a young male mating with a headless female by fully inserting her hemipenis. Specimens were collected, dissected and measured.”

Literary works influence other literary works, as evidenced by a 2020 paper by Marco Colombo and Emiliano Mori of the University of Siena in Italy. the title is”The 'corpse bride' strikes again: first report on Davian behavior in Eurasian badgers”.

Delightful yet scary title

Some medical papers have very intriguing and frightening titles. For those who like horror novels, the title will almost make you want to skip reading the study itself.

Why avoid a complete study? Because when a person's imagination is overstimulated, it can conjure up strange things. By comparison, the actual details you can go and see for yourself may seem mundane, dull, and even relatively boring. Reading them can lead to literary disappointment and dissatisfaction, and in some cases even death of curiosity.

For example, consider a paper written by a medical team in Chiba, Japan. For non-experts, this book describes how doctors solve accidental jigsaw puzzles, puzzles made of strange parts from a person's digestive system. Please read the title of the paper carefully.Risk factors for unintentional partial resection in endoscopic mucosal resection for colorectal polyps larger than 10 mm”.

UK’s JET fusion reactor achieves highest energy output in the world

A 40-year-old nuclear fusion reactor in the UK has set a world record for energy output in its final run before permanent shutdown, scientists have announced.

The Joint European Taurus (JET) in Oxfordshire began operations in 1983. During its operation, it briefly became the hottest point in the solar system, reaching 150 million degrees Celsius.

The reactor's previous record was in 2021 for a reaction that lasted five seconds and produced 59 megajoules of thermal energy. However, it surpassed this in its final test in late 2023, using just 0.2 milligrams of fuel to sustain the reaction for 5.2 seconds, reaching an output of 69 megajoules.

Inside the JET fusion reactor

eurofusion

This corresponds to an output of 12.5 megawatts, enough to power 12,000 homes, Mikhail Maslov of the UK Atomic Energy Agency said at a press conference on February 8.

Today's nuclear power plants rely on nuclear fission reactions, in which atoms are shattered to release energy and small particles. Fusion works in reverse, pushing smaller particles together into larger atoms.

Nuclear fusion can produce more energy without any of the radioactive waste produced by nuclear fission, but there is still no practical way to use the process in power plants.

JET trains atoms of two stable isotopes of hydrogen, deuterium and tritium, together in a plasma to create helium, releasing a huge amount of energy at the same time. This is the same reaction that powers our sun. This is a type of fusion reactor known as a tokamak, which uses rings of electromagnets to contain plasma in a donut shape.

Scientists conducted the final experiment using deuterium and tritium fuel on JET in October last year, and other experiments continued until December. However, the machine is now permanently closed and will be decommissioned over the next 16 years.

Juan Matthews Researchers at the University of Manchester in the UK say many secrets will be revealed during JET's dismantling. For example, how the reactor lining deteriorated from contact with the plasma, and where in the machine the precious tritium, worth around £30,000 a gram, is embedded. You can recover. This will be important information for future research and commercial reactors.

“It's great to have a little bit of a bang,” Matthews said. “It has a noble history. Now that it has served its purpose, we plan to squeeze out more information during the decommissioning period as well. So it's not sad. It's something to be celebrated.”

France's larger, more modern replacement for JET, the International Thermonuclear Experimental Reactor (ITER), is nearing completion, with first experiments scheduled to begin in 2025.

ITER construction project deputy director Tim Luce told a news conference that ITER plans to expand its energy output to 500 megawatts and possibly 700 megawatts.

“These are what I normally call power plant sizes,” he said. “They are at the lowest level of cost required for a power generation facility. Moreover, to obtain high fusion power and gain the timescale needs to be extended to at least 300 seconds, but from an energy production point of view it is probably less than an hour. So what JET has done is exactly a scale model of what we need to do with the ITER project.”

Another reactor using the same design, the Korea Superconducting Tokamak Advanced Research (KSTAR) device, recently succeeded in sustaining a reaction for 30 seconds at temperatures above 100 million degrees Celsius.

Other approaches to creating practical fusion reactors are also being pursued around the world, such as the National Ignition Facility at Lawrence Livermore National Laboratory in California. It fired a very powerful laser into the fuel capsule, a process called inertial confinement fusion, and was able to release almost twice the energy that was put into it.

Midland warehouse workers accuse Amazon of employing ‘union-busting’ tactics

GMB has accused Amazon of resorting to “union-busting” tactics at its warehouse in the Midlands, with a workplace message board telling workers: and you.Labor unions want talks for you. “

The claims come as unions prepare for three days of strike action next week at Amazon’s Coventry warehouse, known as BHX4, as part of a labor dispute that has been going on for more than a year. Staff are demanding a pay rise to £15 an hour and the right to negotiate with the company over pay and conditions.

The Guardian has seen photos from information boards and internal newsletters that GMB claims were on display at BHX4 and other Amazon warehouses in the region. These will display messages similar to the following: ‘The union wants to pay you £14.37 a month to represent you. We believe there should be no price to pay for having your voice heard’, ‘Make your voice heard’ You don’t have to join a union to do it. We’ve got you.”

Another says: “Before you vote or join a union, we encourage you to research the facts for yourself. The best relationships are direct relationships.”

Gary Smith, general secretary of the GMB, said: “What do you want to call it? One of the richest companies in the world working on union-busting right here in the UK.”

He added that GMB members in Coventry “refuse to give in to Amazon’s union busting and they will get the pay and recognition they deserve.”

TUC assistant general secretary Kate Bell, who visited the Coventry picket line last year, said: “Rather than giving workers the respect they deserve, Amazon will do everything in their power to stop workers from organizing for better pay. “I’m working on it,” he said. and conditions. “

GMB’s latest criticism of Amazon comes as the company prepares for a new battle to gain formal recognition in Coventry. The union last year withdrew its application to the Independent Central Arbitration Commission (CAC) and ordered Amazon to add at least 1,000 additional workers to prevent GMB from proving it represented a clear majority of its front-line workers. accused of conscripting people into military service.

The company denied the allegations and said the recruitment of new staff was done as a result of normal business requirements. A concerted membership recruitment campaign continues on the ground, and GMB said it plans to submit a new application to the CAC this spring.

Uber achieves landmark moment with its first annual profit as a limited liability company

Uber reported annual operating profit for the first time as a limited liability company. It was a landmark moment for the company, which has spent billions of investors' money on an aggressive and often controversial expansion around the world.

The US taxi app company announced a profit of $1.1bn (£870m) in 2023, compared to a loss of $1.8bn the previous year.

The milestone has investors speculating about whether Uber will buy back stock or pay investors a dividend. Uber Chief Financial Officer Prashant Mahendra-Raja said the company will share its “capital allocation plan” with investors next week.

Uber stock rose 1% on Wednesday after initially falling. The company's stock has risen by more than a fifth through 2024 and doubled in the past 12 months, giving it a value of nearly $150 billion.

The company said customers have booked 2.6 billion trips in the past three months of 2023, which equates to about 28 million trips per day.

“2023 was a turning point for Uber, proving that we can continue to see strong, profitable growth at scale,” said Dara Khosrowshahi, Uber's chief executive officer. Our audience is bigger and more engaged than ever, and our platform powered an average of nearly 26 million trips every day last year.

Uber was founded in 2009 by entrepreneurs Garrett Camp and Travis Kalanick. Kalanick took over as CEO in 2010 and continued its expansion, during which time the app quickly spread across the United States, followed by Europe and many cities around the world.

This growth has been made possible by Uber's embrace of the gig economy, where drivers in many countries are considered self-employed and are not entitled to things like sick pay or paid time off.

Mr. Kalanick's time as CEO was marked by a series of scandals and battles with regulators. In 2022, leaks reported by the Guardian revealed how Uber broke laws, deceived police, and secretly lobbied governments while rolling out its service.

Mr. Kalanick was replaced in 2017 by Mr. Khosrowshahi, the former chief executive of travel agency Expedia, in an effort to soften the company's image and focus on meeting regulators' requirements.

Dan Ives, an analyst at investment bank Wedbush, said Khosrowshahi has led “one of the greatest turnarounds in tech industry history” and that Uber is “not slowing down.”

Uber has consistently suffered significant operating losses since its stock listing on the New York Stock Exchange in May 2019. Losses increased from $3 billion in 2018 to $8.6 billion in 2019, then declined to $4.9 billion in 2020, $3.8 billion in 2021, and $1.8 billion in 2021. 2022.

Thanks in part to growing demand, the company made a profit in 2023. Gross booking value (the total amount paid by Uber riders and delivery customers) in the final quarter of 2023 increased 22% year over year to $37.6 billion. Uber's profit from these deals was $9.9 billion.

Understanding the Job Cuts in the $180 Billion Gaming Industry

I
It's widely agreed that 2023 was a great year for video games. The Legend of Zelda: Tears of the Kingdom, Baldur's Gate 3, Alan Wake 2, Marvel's Spider-Man 2… Barely a week has passed without a blockbuster or independent masterpiece appearing.

But behind these accolades there is a sadder and more worrying story. This year also saw widespread layoffs in the industry, a trend that continues into the first weeks of 2024. Microsoft laid off 1,900 employees after acquiring Activision Blizzard for $69 billion. .Publisher Embracer Group
lay off at least 900 staff
In addition to shutting down veteran British developer Free Radical Design, it has ended activity across many of the company’s studios. Epic Games, the creator of Fortnite, one of his most successful titles of this decade, has laid off 830 employees.electronic arts
6% reduction in workforce, which equates to approximately 780 jobs. There were similar harrowing stories from Ubisoft, Naughty Dog, Sega, and Unity.Big publishers and small studios alike
is affected

Why did this happen? Why is the entertainment industry, said to be worth $180 billion a year, cutting staff at such an alarming rate?

In some cases, there are certain factors that promote redundancy. In the case of Activision Blizzard, one of the reasons is the duplication of roles after the purchase is completed. “Microsoft obviously already had a publishing business, but they bought ZeniMax Media, Bethesda's parent company, and another publishing business,” said James Batchelor, editor-in-chief of GamesIndustry.biz. “The company then acquired two publishing businesses, Activision and Blizzard, which operated somewhat separately. Think about the number of departments that have doubled here, including human resources, public relations, marketing, and accounting. So you end up with a lot of people doing the same job within the same company. This is a case of rationalization.”




Even though Fortnite has been a huge success, the publisher is still cutting back on employee numbers.

Sweden's Embracer Group is a game publisher that owns 135 studios around the world, including Tomb Raider creator Crystal Dynamics. After a period of accelerated expansion, the company was forced to close developers, cancel games, and make staff redundant. “The company had a very aggressive merger and acquisition strategy, but we now know that it was dependent on outside investment,” Batchelor said. “But last year, deals worth at least $2 billion were reportedly struck by Saudi investors.
was canceledThis meant we had to make major adjustments to our plans. Embracer is a classic example of a company that is too big to survive. There are thousands of people working on the Embracer game, but we didn’t have a big seller to sustain that number. ”

However, one event looms large in the background: the new coronavirus pandemic. Interest in video games exploded during lockdown. He had two effects. For one thing, strong sales of titles like “Animal Crossing” and “Call of Duty: Modern Warfare” have boosted revenues and sent stock prices soaring, attracting the attention of outside investors and flooding the industry with money. That means I did it. In response, arrogant publishers commissioned more ambitious projects and hired accordingly.

But the bubble didn't last. Sales declined as lockdowns eased and people continued to live their lives. “We've seen a lot of games canceled over the last few months. I think there are more that we just don't know about,” Batchelor says. “If we cancel a project and focus on a few games that we know will do well for the studio, we will unfortunately be putting the jobs of the people working on the projects that are being scrapped at risk.”

The solution for many publishers has been to cut back on riskier projects and focus on “sure-fire” hits, but this may just be perpetuating the cycle. McDonald explains: “Publishers are signing fewer games, development costs are lower, and it takes longer to sign deals, but if you leave them without all the promising games for the next few years, You put yourself at risk.”

Macdonald believes there may be a bandwagon effect. “We're at a stage now where so many studios are having so many layoffs that some companies think it's an opportunity to make layoffs for more specific reasons. , many other studios will be in the spotlight for job losses. It's especially unfortunate that companies with billions of dollars in cash jumped on the bandwagon and made mass layoffs, and that cash It is likely that the interest increase alone could have covered all of these salaries.

Given the gloomy start to 2024, the effects of coronavirus and various acquisitions across the industry are likely to continue to impact the gaming business. And even if it recovers, another threat looms over staff: the rise of artificial intelligence in development and production processes. “We don't know how widely AI tools are being deployed, but there is talk that some reductions are being made in hopes of leveraging AI for content creation.” McDonald says.

For publishers looking to reduce development costs, the use of AI can be attractive, especially in areas such as quality assurance and performance capture. In January, the Sag-Aftra union

I wrote to X: “I sacrificed going on strike for half of the last year to keep my profession instead of hoarding AI replicas.”

With their livelihoods threatened, more development staff are seeking to unionize, increasing pressure on the industry to self-regulate. Incumbent publishers are starting to see both as threats. Last June,
Electronic Arts Financial Report We have identified unionization and AI regulation as having the potential to negatively impact our business and performance.

So how can newcomers to the gaming industry protect themselves? “At the end of the day, job seekers always have to look out for themselves,” McDonald says. “Check if the company is profitable, has a history of layoffs, and if salaries are sustainable.”

Video game companies also have a responsibility to reflect on the past year and learn from it. But what lessons might they learn?

“I think the industry is going to get more attention and focus on known hits and safer bets,” Batchelor said. “This is unfortunate because the industry still needs to take risks. But ultimately those risks need to be maintained and funded by companies, rather than relying on external investment.”

“As companies become more streamlined and more sustainable, we hope to create a smarter industry.”

January Breaks Record as Hottest Month; Global Temperature Surpasses 1.7°C Rise

Devastating wildfires break out in Chile following January's heat wave and drought

Temperature records continue. According to the European Union's Copernicus Climate Change Agency, January this year was the hottest on record, with temperatures 1.7 degrees Celsius above the pre-industrial average.

This means there were 12 months in which the Earth's average surface temperature was more than 1.5 degrees Celsius above the average between 1850 and 1900, the pre-industrial reference point.

“2024 begins with another record month,” Samantha Burgess of the Copernicus Climate Change Service said in a statement. She said: “Rapid reductions in greenhouse gas emissions are the only way to stop global temperatures from rising.”

At the 2015 Paris Climate Conference, countries pledged to work to prevent global temperatures from rising more than 1.5 degrees Celsius above pre-industrial levels. Climate scientists will not consider this limit to have been breached until the Earth's long-term average temperature exceeds this level for many years.

The long-term average is now 1.25°C warmer than before the industrial revolution. Richard Betts At the Met Office, the UK's National Weather Service. However, carbon emissions are still increasing, and by this standard it seems certain that the 1.5°C limit will be breached soon, perhaps around 2030.

Long-term global averages are rising in line with climate model predictions. However, the extremely rapid warming over the past year or two has far exceeded expectations. Among other records, in 2023 he recorded for the first time a day warmer by 2 degrees Celsius than the average from 1850 to 1900.

It remains unclear why there has been such rapid warming over the past year or so, and how long it will continue. Factors that may have accelerated warming include the 2022 eruption of Tonga Volcano, which pumped large amounts of water into the stratosphere, and reduced aerosol pollution from ships.

For practical reasons, climate scientists have defined pre-industrial temperatures as the average from 1850 to 1900, since there are few records of temperatures before then. However, using this as a baseline could mean that the level of warming due to fossil fuel emissions is being underestimated.

One 2017 survey This indicates an error of approximately 0.2°C. Another announcement this week put the difference at 0.5°C, based on analysis of sponges, meaning we have already breached the 1.5°C limit, but other climate scientists They are not satisfied with this.

UGC 3912also known as IRAS 07315+0439 or LEDA 21303, lies. 19.3 megaparsecs It is located in the constellation Canis Minor (63 million light years) from Earth.

“UGC 3912 is classified as a spiral galaxy, but you wouldn't know it from this detailed Hubble image,” said Hubble astronomers.

“This galaxy's distorted shape typically indicates a gravitational encounter with another galaxy.”

“When galaxies interact, meaning they bump into or collide with each other's gravitational fields, their stars, dust, and gas can be pulled into new paths.”

“UGC 3912 may have once been an organized-looking spiral, but now it appears to have been bent out of shape by a giant thumb.”

“Fortunately, when galaxies interact, individual stars and objects orbiting them remain intact, even though their orbits change dramatically and the shape of the galaxy as a whole changes.”

“That's because the distances between stars in galaxies are so great that they simply keep moving along new orbits without colliding with each other.”

Astronomers are studying UGC 3912 as part of their investigation into supernova activity. Supernova activity is when a star at least eight times the size of the Sun explodes at the end of its life.

“Hubble studies hydrogen-rich phenomena known as supernovae, one of several types of supernovae. Type II supernova” they explained.

“Although enough Type II supernovae have been observed, they exhibit highly variable properties in brightness and spectroscopy and are not well understood.”

Confirmation of Two Newly Discovered Carboniferous Ctenacan Shark Species in the United States

An intensive search for ancient marine vertebrates in Mammoth Cave National Park's paleontological resource inventory has yielded a wealth of new fossil data. To date, paleontologists have identified marine vertebrate fossils from four major formations within the park, two of which are the first of marine vertebrate fossils to occur in those formations. It's a record. The Mammoth Cave ruins have yielded more than 70 species of ancient fish, approximately 90% of which are cartilaginous fish (sharks and related species), including two new species: I am. Troglocladodus trimbley and Grikmanius Care Forum.

Mammoth Cave National ParkLocated in central Kentucky, it is home to the longest cave system in the world.

To date, more than 685 km (426 miles) of corridors within 214 km have been mapped.2 It forms a park. In addition, within the boundaries of the park there are more than 500 small caves.

These cave passages date back 340 to 325 million years and were formed by dissolution by underground rivers, streams, and other drainage channels that cut through a series of limestones covered with durable sandstone. I did.

These passages opened up unique views of these limestones. Limestone is a time capsule containing a wealth of information about the ancient marine environment at the time of its deposition.

From these layers, invertebrate fossils such as horned corals, fan-like bryozoans, brachiopods, gastropods, shelled cephalopods, and a variety of echinoderms are found throughout the various strata that form the cave. It has been.

“Every new discovery at Mammoth Cave is made possible because of collaboration,” said Superintendent Barclay Trimble.

“Our parks team is proud to collaborate and collaborate with the National Park Service Paleontology Program and now the University of Alabama Department of Geological Sciences to make this latest announcement possible.”

The two new species are stenacanto shark, Troglocladodus trimbley and Grikmanius Care Forumlikely hunting in an ancient coastal habitat that covered Kentucky and Alabama more than 325 million years ago.

This region was once an ancient sea route connecting what is now eastern North America, Europe, and North Africa, but it later disappeared with the formation of the supercontinent Pangea.

Troglocladodus trimbley It was identified from adult and juvenile teeth found in St. Louis and St. Louis. Genevieve Formation and Bangor Formation of Mammoth Cave.

The ancient shark is estimated to have reached about 3 to 3.7 meters (10 to 12 feet) in length, about the same size as the oceanic white shark.

Grikmanius Care Forum It was mainly identified from teeth in St. Louis, St. Louis.Genebabe and Haney Formations in Mammoth Cave, Hartselle and Bangor Formations in Alabama, but a partial set of jaws and gills from a young specimen Grikmanius Care Forum It was also discovered in Mammoth Cave.

The body length of this species was 3-3.7 meters. The shape of its jaws suggests that it had a short head with a powerful bite to hunt small sharks, bony fish, and right-cone-shaped creatures like squid.

“This discovery pushes the origin of the Ktenacanto shark back more than 50 million years earlier than expected,” the paleontologists said.

Research: How small structures in the wax coating of blue-pigmented fruit contribute to its blue color

It is perhaps surprising that fruits with blue pigments are less common, since many visually guided fruit eaters have eyes highly adapted to blue sensitivity. However, some fruits do not contain blue pigment. In a new study, scientists from the University of Bristol and elsewhere investigated dark fruits with wax blooms, such as blueberries, plums and juniper cones, and found that structural color mechanisms are involved in their appearance. Did.

The structural color of the wax bloom gives the fruit a blue appearance across a wide range of accessions. (A) Undamaged highbush blueberries growing on the plant. (B) Blueberry (i) unmodified wax, (ii) mechanical wax removal, (iii) chloroform wax removal, (iv) surface application of (approximately) index-matched oil, (v) surface application of water; (vi) peeling off the outer skin to expose the pulp; (vii) the underside of the peeled skin; (C) Transmission light microscopy of a blueberry peel peeled from the inner edge showing red pigmentation of epidermal cells.

(D) (i and ii) Plum selection (Plum) Fruits with different cell pigmentation, (i) with wax intact and (ii) with wax removed.Image credit: Middleton other., doi: 10.1126/sciadv.adk4219.

“You can't 'extract' the blue color from blueberries by crushing them, because blueberries are not present in the highly pigmented juice that can be squeezed from the fruit,” said lead author Dr Rocks Middleton, a researcher at the University of Bristol.

“That's why I knew there had to be something strange about this color.”

“So we removed the wax and recrystallized it on the card. In doing so, we were able to create a completely new blue UV coating.”

This ultra-thin colorant is about 2 microns thick, has a low reflectance, but looks blue and reflects UV well, potentially paving the way for new colorant methods.

“This shows that nature has evolved to use a very neat trick: an extremely thin layer of a vital colorant,” Dr Middleton said.

Most plants are covered with a thin layer of wax, which has multiple functions, many of which are still unknown to scientists.

They know that it is highly effective as a hydrophobic, self-cleaning coating, but only now have they realized how important this structure is for visible coloration.

Now Dr. Middleton and colleagues plan to look at easier ways to recreate and apply the coating.

This could lead to the development of more sustainable, biocompatible, and even edible UV- and blue-reflecting paints.

Additionally, these coatings may have multiple functions similar to natural biological coatings that protect plants.

“It was really interesting to discover that there was an unknown coloration mechanism just beneath the surface of the popular fruit that we grow and eat all the time,” Dr Middleton said.

“It was even more exciting to be able to recreate that color by taking wax and creating a new blue coating that no one had ever seen before.”

“Our dream is to incorporate all the functionality of this natural wax into a man-made material.”

Killer whale pod trapped in drift ice off the coast of Japan vanishes

Killer whale trapped in ice off the coast of Japan

NHK/Screenshot

A pod of more than a dozen killer whales has gone missing after languishing in Japan's icy waters for nearly a day, trying to escape being trapped in an ice floe. It is unknown what happened to them, but they may have died.

Fishermen near Hokkaido first noticed the pods struggling in the thick mud early Tuesday morning. Images and drone video show at least 12 orcas. Several boys struggle in a small space It was trapped in heavy ice about 1 km offshore.

As of Wednesday morning, The containment area was empty.Japanese news outlet NHK said it gave hope that the animals may have escaped to the open waters of the Sea of ​​Okhotsk.

However, late Tuesday afternoon, a pod of 17 orcas was found trapped on an ice floe 2 kilometers northeast of their original location. NHK reporting.

“Orcas are not ice-adapted whales. They are not comfortable in this area.” colin galloway at the University of Manitoba, Canada. “So they are definitely experiencing the stress of confinement and are more likely to be starving.”

Cetaceans that permanently inhabit the Arctic region, such as narwhals (Monodon Monoceros) and belugas (Delphinapterus leucas), can sometimes become trapped in ice. Killer whale (killer whale) However, they usually avoid heavy ice and avoid getting trapped.

Still, black-and-white marine mammals can end up in icy waters at the wrong time.in 2016 reviewScientists found that since 1840, there have been 17 incidents in the Northern Hemisphere where a total of 100 orcas were trapped in ice. Almost half of them occurred in the Sea of ​​Okhotsk, Japan. Confinement usually ends in the killer whale's death, Galloway said.

Scientists believe that even the reported orcas “broken freedomAfter being trapped in the ice, they can die struggling through further ice drifts while trying to reach the open sea.

A 2019 study of ice-trapped killer whales suggests that: Mammals can live on body fat for up to 50 days before being trapped and starving to death.. Sightings of orcas trapped in the ice have increased in recent years, as the Arctic ice melts and curious orcas seek new territory to explore.

Global warming may indeed be playing a role, Galloway says. His team is currently investigating the environmental impact of killer whales' gradual northward migration. But it's also possible that entrapment incidents simply appear to be more common because people are reporting more incidents.

“Just because we've gotten better at detecting, observing, and recording climate warming, and we're more interested in it, it's very difficult to disentangle the relationship between climate warming.” “That's one of the predictions,” he says.

Using Inhalable Nanoparticles to Treat COPD, a Chronic Lung Disease

Chronic obstructive pulmonary disease affects the lungs

Sebastian Kauricki/Science Photo Library

Using inhalable nanoparticles to deliver drugs to the lungs could help treat chronic obstructive pulmonary disease (COPD). In mice with signs of the condition, treatment improved lung function and reduced inflammation.

COPD causes the airways in the lungs to gradually narrow and stiffen, blocking airflow and blocking mucus drainage. As a result, mucus builds up in the lungs, attracting bacterial pathogens that further worsen the disease.

This thick layer of mucus also traps drugs, making it difficult to treat infections. So, Zhu Junliang Researchers at China's Dongzhou University have developed inhalable nanoparticles that can penetrate mucus and deliver drugs deep into the lungs.

The researchers constructed hollow nanoparticles from porous silica and loaded them with an antibiotic called ceftazidime. A shell of negatively charged compounds surrounding the nanoparticles blocked the pores and prevented the antibiotic from leaking. This negative charge also helps the nanoparticles penetrate mucus. The slight acidity of the mucus then changes the charge on the shell from negative to positive, opening the pores and releasing the drug.

Researchers used an inhalation spray containing nanoparticles to treat bacterial lung infections in six mice with signs of COPD. A similar number of animals received antibiotics only.

On average, mice treated with nanoparticles had about 98 percent fewer pathogenic bacteria in their lungs compared to mice given antibiotics alone. They also had fewer inflammatory molecules in their lungs and less carbon dioxide in their blood, indicating better lung function.

These findings suggest that nanoparticles could improve drug delivery to people with COPD and other lung diseases such as cystic fibrosis, where thick mucus makes infections difficult to treat. It has said. vincent rotello from the University of Massachusetts Amherst was not involved in the study. However, it is unclear whether these nanoparticles are cleared from the lungs. “If you have a delivery system that accumulates over time, that's a problem,” he says.

A possibly magma-covered super-Earth with the appearance of an ocean

Diagram of exoplanet K2-18b based on scientific observations

NASA, ESA, CSA, Joseph Olmstead (STScI)

The types of planets thought to be able to support life may actually be covered in hot magma. Previously thought to have oceans of liquid water, the chemistry of these so-called high sea exoplanets may instead indicate oceans of magma.

Oliver Shortle Researchers from the University of Cambridge used observations from the James Webb Space Telescope (JWST) of the exoplanet K2-18b to reach this conclusion. This world is typically Hycean. This is the name given to a planet with a hydrogen-rich atmosphere above a liquid ocean. These planets also tend to be between Earth and Neptune in size, and the chemicals in their atmospheres suggest the presence of liquid water on their surfaces, making them a prime search for extraterrestrial life. It has become a target.

But recent models of K2-18b's climate suggest it may be hotter than previously thought, hot enough to cause oceans of water to boil away long ago. “From a theoretical perspective regarding the situation here on Earth, it's like the ground is moving beneath our feet,” Schotle says.

The researchers investigated how it would affect Earth's atmospheric chemistry if these oceans were made of magma instead of water. This would be consistent with the expected high temperatures. They found this to be consistent with his JWST observations as well as water bodies.

“These two fundamentally different regimes are very similar,” Schotle says. “Detecting habitable conditions for super-Earths and sub-Neptune-sized planets will be more complex than we expected.”

This means that we probably need more detailed data to tell the difference between a potentially habitable world with oceans of water and a world of burning, inhospitable magma. For K2-18b, Schotle said his additional JWST observations over the next few years should resolve this issue. And when it comes to other Heim worlds, we may need to develop new ideas for how to find liquid water.

Study suggests Mimas, one of Saturn’s moons, could be responsible for forming Earth’s oceans beneath its icy shell

From a detailed analysis of Mimas’s orbital motion based on data from NASA’s Cassini mission, planetary researchers from the Sorbonne, the University of Nantes, Queen Mary University of London, Franche-Comte University, and Jinan University have discovered that the heavily cratered They showed that some ice shells hide recently formed ice shells. (less than 2-3 million years ago) global ocean 20-30 km deep.



The surface of Mimas, like the surfaces of other major Saturn moons that do not have atmospheres, is not pure ice but contains some black impurities. Relatively dark markings appear along the lower part of the walls of the 130km-wide Herschel Crater (the crater's central peak is about the same height as Mount Everest); the impact may have all but destroyed the Moon. there is). some small craters. Scientists interpret the darkening as evidence that the impurities have gradually become concentrated as icy material evaporates in areas where they are slowly sliding down the crater walls. Image credit: NASA / JPL / Space Science Institute.

There is growing evidence that some moons may have oceans beneath their surfaces, but such watery worlds are difficult to detect.

Mimas — Saturn's innermost and smallest (radius = 198.2 km, or 123 miles) regular moon — is an unlikely candidate due to the different nature of its surface compared to other icy moons such as Enceladus .

This theory has been challenged by Sorbonne University researcher Valerie Rainey and others who are evaluating Cassini's observations of small satellites.

Previous research suggests two possibilities inside Mimas. It is either an elongated rocky core or a global ocean.

A new study reveals that the small moon's rotational motion and orbit change due to internal influences.

For the solid-state model to apply, the rock core must be elongated and approximately pancake-shaped, which is inconsistent with observations.

Rather, measurements of Mimas' position suggest that the evolution of its orbit is better explained as influenced by an internal ocean.

The researchers calculate that the ocean lies beneath an ice shell about 20 to 30 kilometers deep.

Their simulations suggest that it appeared between 25 and 2 million years ago.

Therefore, signs of such an underground ocean would not have had time to leave traces on the surface.

This result suggests that recent processes on Mimas may have been common during the early stages of the formation of other ice worlds.

“Mimas was a small moon with a cratered surface and no sign of an ocean hidden beneath,” said co-author Nick Cooper, a researcher at Queen Mary University of London. the doctor said.

“With this discovery, Mimas joins an exclusive club of moons with inland oceans, including Enceladus and Europa, but with a unique difference: its oceans are surprisingly young.”

Possible Vast Global Ocean Discovered Beneath Ice on Saturn’s Moon Mimas

Mimas photographed by NASA's Cassini spacecraft

NASA/JPL-California Institute of Technology/Space Science I

Saturn's moon Mimas appears to have a vast global ocean beneath its icy shell, according to detailed measurements of its orbit. If other icy worlds have similar oceans, the number of planets that can support life could increase.

Mimas is the smallest of Saturn's seven major moons. For a long time, it was thought that most of it was composed of solid ice and rock, but in 2014 astronomers observed that the orbit around Saturn was unexpectedly wobbling, suggesting that this could only be explained by either a rugby ball-shaped nucleus or a liquid ocean.

Many astronomers rejected the ocean explanation, as the friction required to melt the ice would have caused visible marks on Mimas's surface. However, recent simulations suggest that this ocean may exist even without such traces.

Looking for more clues? Valerie Rainey Researchers from France's Paris Observatory analyzed observations of Mimas' orbit by NASA's Cassini spacecraft. They found that the orbit around Saturn has shifted by about 10 kilometers over 13 years.

According to the team's calculations, this orbital drift could only have been caused by an ice shell sliding over the ocean, or by wobbles from the physically impossible pancake-shaped core.

The moon's elliptical orbit and lack of surface markings also suggest that the ocean is about 30 kilometers deep and formed less than 25 million years ago. “It was very recent,” Rainey says. “We are more or less witnessing the birth of this global ocean.”

This recent activity could help explain not only the lack of traces on the surface, but also why the moon is so different from its neighbors. Enceladus has a similar shape and orbit to Mimas, and has a global ocean, but it also has a very active surface and giant spout. Rainey said the difference is simply a difference in time, and in a few million years Mimas' ice could melt and it could look similar to Enceladus.

“It would be surprising if that were true,” he says. William McKinnon at Washington University in St. Louis, Missouri. But he says there are still things that aren't perfectly aligned, such as the vast 80-mile-wide Herschel crater, which was formed by a giant impact. If Mimas' ice shell was truly only tens of kilometers deep, McKinnon said, we would have seen evidence of a distorted crater floor in the impact and aftermath. It's also unlikely, he says, that you'll be able to get a front-row seat at such a short and unique time in Mimas' long history. “I remain a Mimas ocean skeptic,” McKinnon says.

However, if Mimas has a hidden ocean, it suggests that other icy planets and moons in the solar system and elsewhere may have the same, expanding the possibility of life. “It's expanding our vision of what is and isn't a habitable world,” Rainey says. “Mimas teaches us that even a corpse that seems to have no life in it may someday come to life.”

Ondo Finance Introduces Real-World Assets and High-Yield Stablecoin USDY to Sui on Blockchain Platform

Grand Cayman, Cayman Islands, February 7, 2024, Chainwire

Ondo’s upcoming integration of Sui will provide native access to new tokenized assets such as on-chain treasuries, securities, and stablecoins.

Sui, a Layer 1 blockchain that has seen explosive growth since its launch eight months ago, today announced that Ondo Finance is expanding into the Sui ecosystem. With this expansion, Sui Network’s first native dollar-denominated token (including stablecoins and interest-bearing stablecoin alternatives) will be available in the form of Ondo USD Yield or “USDY” (a U.S. Treasury-backed interest-bearing token issued by Ondo).

Ondo’s expansion to Sui further builds on Sui’s ferocious DeFi momentum and demonstrates the growth and demand for financial applications and native on-chain functionality. Sui’s DeFi volume has increased over 1200% since October, and Sui recently ranked in the top 10 of his DeFi ecosystem as measured by TVL.

Ondo Finance is the third largest platform bringing tokenized derivatives of real-world assets onto public blockchains, with $185 million in new TVL launches in the first week of late January There is over $1 billion in governance token transactions. In addition to stablecoins, Ondo’s flagship Treasury-backed tokens, tokenized securities, and real-world assets create countless new opportunities for Sui-based teams.

Ondo’s expansion into the Sui ecosystem also continues the trend of top projects actively choosing to integrate into Sui. For example, in December 2023, Solend, the leading Solana lending protocol, announced the launch of a Sui-native lending protocol, and decentralized derivatives exchange Bluefin similarly announced the launch of V1 Arbitrum to focus entirely on Sui. Implementation finished.

“People using our platform expect fast and efficient transactions, which should be essential for any blockchain project,” said Nathan Allman, Founder and CEO of Ondo. ”. “Sui’s growth and network performance clearly confirms that the network is a great fit for his Ondo ecosystem.”

Tokenized Treasury products represent tradable tokens backed by real-world assets, and their presence on Sui is an important step toward growing DeFi across the ecosystem and industry. It becomes.

“Ondo is an amazing addition to the Sui ecosystem, creating new opportunities for Sui builders and developers, and creating a stablecoin-like offering with native yield that provides essential new functionality to users of their applications. Provide assets.” Sui Foundation. “Sui’s DeFi volume is already growing at an incredible rate, and the addition of Ondo will make that trajectory even stronger. I'm looking forward to seeing how you use it.”

Philadelphia Museum of Science under investigation after receiving package with two preserved fetuses

Philadelphia police are investigating the origin of a package containing two preserved fetuses in glass bottles that was sent to the city’s Museum of Medical Sciences.

Museum staff reported receiving the package on Tuesday morning, according to a police statement.

The package was addressed to the museum curator, had no return address, and contained a letter from someone claiming to be a retired doctor, stating that the two specimens were a gift to the museum.

“There is no proper documentation, provenance or information that would allow us to accept it,” says Mütter Museum curator Anna Dodi. told NBC Philadelphia.. “Obviously they looked like human remains, so we had to call the authorities.”

of Mutter Museum It is part of the Philadelphia College of Physicians and features a collection of preserved anatomical specimens, models, and medical instruments.

The museum accepts donations, especially those involving human remains, but the process requires research and a detailed explanation of the object’s history.

Dody, who has been the museum’s curator for nearly 20 years, said the donation was “unusual, unusual and completely inappropriate procedure.” She told NBC News to discourage others from sending such “unsolicited anonymous remains.”

The fetus was handed over to the medical examiner’s office for further investigation. Philadelphia Police will provide additional information as it becomes available.

Cybercrime: Record $1.1 billion paid in ransom by hacking victims last year

Ransomware gangs experienced a resurgence last year, with victims paying $1.1 billion to hackers, a record high according to a study.

Following a lull in 2022, cybercriminals intensified operations in 2023, targeting hospitals, schools, and major corporations worldwide.

Chainalysis, a cryptocurrency research firm, reported that ransom payments doubled compared to 2022, with $567 million paid out that year.

The report highlighted the “big game hunting” aspect of attacks last year, with a higher proportion of ransom payments exceeding $1 million as wealthier companies were targeted.

“2023 will be the year of a major resurgence in ransomware, with record payout amounts and a significant increase in the scope and complexity of attacks. This is a significant reversal from the decline observed in 2022,” Chainalysis said.

In a ransomware attack, hackers typically infiltrate a target’s computer system, infect it with malware, and encrypt files, rendering them inaccessible. New trends involve attackers extracting data such as staff and customer details from IT systems and demanding payment to unlock the files or delete stolen data copies.

Chainalysis attributed the decline in payments in 2022 to factors including Russia’s invasion of Ukraine. Most ransomware groups are linked to Eastern Europe, the former Soviet Union, and Russia. Some fraudsters have been disrupted or turned ransomware into politically motivated cyberattacks.

The FBI disrupted the Hive ransomware group by obtaining their decryption keys and preventing victims from paying a $130 million ransom. Chainalysis also cited research showing a rise in the number of attackers and ransomware variants involved in attacks over the past year.

“The main thing we’re seeing is an astronomical increase in the number of attackers conducting ransomware attacks,” said Alan Liska, an analyst at cybersecurity firm Recorded Future.

According to Recorded Future, 538 new ransomware variants are expected in 2023, indicating the emergence of new and independent groups. The Clop group emerged as a key player last year by claiming responsibility for the hack of payroll provider Zellis, affecting customers like British Airways, Boots, and the BBC.

The British Library is still recovering from a ransomware attack by the rebranded group Rhysida that targeted the library in October.

The growth of ‘ransomware-as-a-service’, renting malware to criminals in exchange for a share of the profits, and the activity of ‘initial access brokers’ who sell vulnerabilities in potential targets’ networks to ransomware attackers have become trends.

Ellie Ludlum, a partner specializing in cybersecurity at British law firm Pinsent Masons, anticipates the rise in attacks to continue. “This increase is expected to continue in 2024, with continued focus on mass data exfiltration by threat actor groups, which may result in increased ransom payments by affected companies,” she stated.

Brendan Hancock’s List of the 10 Most Hilarious Internet Finds | Comedy

L
Last year, I was punched in the nose by a lesbian during a Monday night coed football game. It was Tim Winton’s dreamy evening. The jacarandas were fresh and blooming, and at the end of the year, that manicured fist touched my face squarely, if only by chance. People laughed, as millennials naturally do at violence that made sense to the first internet generation, who grew up on a diet of Australia’s funniest home videos and Mad TV music parodies (unfortunately, none of these make the list).

As a silly gay clown, laughter is my currency. I look forward to walking you through the order of neuroses that have plagued me for millennia. So let’s get in my brain, his broken 1993 Honda Civic, and drive around the old internet guy’s lane.

1. Actress

Every gay man has a ride-or-die diva, and mine is unashamedly Emma Stone. This SNL sketch, written by famous homos Bowen Yang and Julio Torres, is pristine. You can imagine a beautiful world by thinking about other points of view. And yes, that includes wives being cheated on with gay porn. Bravo.

2. The struggle of Amsterdam housewives

Beast. Let’s talk about her husband. These aren’t punch lines, but very well executed takedowns. The building and building drama of this scene is perfect. Private has become public. Do you realize I still have Hecs debt for my communications degree and haven’t started paying it off yet?

3. George Michaels Outside

Forget about the handsome guy in the Senate. Because George Michael’s Outside music video has the most cheek. Camp has its own unique sense of humor, and this is a masterclass in applause. Nineties outings aside, there’s a punch line that says, “I want to serve my community, and I’m already doing that,” and there’s also a bathroom disco cruising show and Tom of Finland drag. There’s no doubt that one of my favorite videos of his is about going outside.

4. Mama Makes Me Milo

I often say that tragedy and time are comedies, but it’s boring, and I don’t like being bored. I’m more of a comedy equivalent of Hot Department mixed with childhood nostalgia. If I’m laughing out loud alone in my house, most of the time it’s because of this devil. I couldn’t ask for a higher compliment. Check out this sketch to see your good constitution.

5. Kim Cattrall cheated on her husband

Not to beg, borrow, or steal from another funny list (looking at you, Madeleine Gray), but on the same day we both sat in the backyard of a gay bar in Santa Monica drinking margaritas. When I was there, I was asked to write this column. Immediately after the match, we both knew this was going to be a winner. Seriousness. “scat”. All I know is that her husband can play me like an upright bass any day. What a fuss!

6. Caleb Hearon performs the sacred art of stand-up comedy

If you follow any stand-up comedian on any platform these days, you’re likely inundated with crowd work clips. It seems like an easy way to generate content without wasting material constantly trying to exploit algorithms. They’re controversial in the community, but we’re all just shouting into the void for attention, so give them all the power. This clip by Caleb Hearon ignores all that and is just classic stand-up.

Retired employee sues bank after losing virtual currency fund in Hyperverse

Catalina de Solieu had high hopes for a comfortable retirement. She had completed her career as a nurse, paid off the mortgage on a property in regional Victoria, and had savings in the bank.

A friend from a network marketing group introduced her to an investment opportunity called Hyperfund, with the promise of using the returns as a source of income for her retirement. After initially investing small amounts, she eventually invested $80,000.

Within a few months, the money vanished.

“I lost my home,” she says three years later. “I lost all my money. I couldn’t pay the mortgage. When I actually sold the house and paid off the rest of the mortgage, I was in a lot of debt. By that time I had no money. There wasn’t much left.”

Now 71, de Solieu says she lives on a pension that barely covers her rent.

“Right now, I don’t have a nickel in the bank or in my pocket. I can’t go to the dentist. I can’t get my car serviced properly.

“It goes on and on. I can’t get it either. [hearing] Checked out. I even had a friend deliver groceries to my door. I have nothing left. ”

This experience left de Solieu feeling depressed and suicidal.

“I became so depressed that I wanted to commit suicide. It’s a terrible thing for anyone to admit, but that’s how I felt.

“I still wake up every morning and sob. Ever since that happened, every morning I can’t get up because I don’t forgive myself and I want to beat myself up.”

China unveils the largest onshore wind turbine blade in the world

Blades forming part of the world's largest onshore wind turbine

Sanichi Renewable Energy

The largest onshore wind turbine blade in world history has been manufactured in China. Each foil is 131 meters long, enough to dwarf Big Ben or the Statue of Liberty.

Once installed in central China in the coming months, each structure containing a 15-megawatt turbine and three blades will be more than 260 meters in diameter.

The SY1310A onshore wind turbine blades were manufactured by SANY Renewable Energy at its factory in Bayannur, northern China.

The company said in a statement that the longer blade length increases requirements for stiffness and strength, as well as the need for protection from extreme weather events such as lightning strikes.

“Several advanced innovations have been applied to this blade, including a high-performance airfoil with a thick, blunt trailing edge, an optimized airfoil layout, and increased overall thickness.” .

Peter Majewski Researchers at the University of South Australia say the advantage of such large wind turbines is that the larger they are, the fewer turbines are needed. “But the bigger they are, the more visible they are, so it has to be socially acceptable to build such large structures,” he says.

“These are huge structures that are expensive to build and just as expensive to remove.”

Wind turbine blades may continue to grow in size, but the logistics of transporting such huge blades make their use difficult, Majewski said. It also says manufacturers and society need to consider what will happen to these structures as they age.

Majewski is researching the issue of recycling wind turbine blades.in 2022 surveyHe and his colleagues predicted that tens of thousands of tons of wind farm blades could have to go to landfill by 2050, when existing turbines reach the end of their 20- to 30-year lifespans.

However, he welcomed the use of recycled polyurethane as part of the construction of these newly announced blades.

Snap stock’s growth takes a hit amidst growing concerns | Technology

Snapchat’s owner narrowly missed Wall Street’s hopes as it continues to grapple with slowing digital advertising. The social media company’s stock price fell by nearly a third.

Snap said it was “encouraged by our progress,” but cited factors such as the Middle East conflict that had hurt its business.


Snap’s revenue rose 5% to $1.36 billion in the three months ended Dec. 31, missing analysts’ expectations for $1.38 billion. Net loss narrowed from $288 million to $248 million.

Investors remained concerned about the company’s growth. The company expects revenue for the current quarter to be between $1.1 billion and $1.14 billion. Analysts had expected about $1.1 billion.

Snap shares fell 30% to $12.21 in after-hours trading in New York.

Alphabet, owner of Google and YouTube, the world’s two biggest advertisers, and Meta Platforms, owner of Facebook and Instagram, are in a better position. Smaller companies in the market continue to struggle.

Santa Monica, Calif.-based Snap expects to end 2023 with about 414 million daily active users, a number that will rise to 420 million in the first quarter.

The group told investors on Tuesday that it was “shifting our focus to user growth and deepening our engagement in our most profitable regions, including North America and Europe.”

Evan Spiegel, CEO of Snap, said: “2023 was a pivotal year for Snap. We transformed our advertising business and continued to grow our global community, reaching 414 million daily active users.” We have 7 million subscribers who pay for our products.

“Snapchat strengthens our relationships with friends, family and the world, and this unique value proposition has provided a strong foundation on which to build our business for long-term growth.”

The company releases its financial results a day after announcing it would lay off about 10% of its global workforce, or about 530 people, as part of an organizational restructuring to “reduce hierarchy and increase in-person collaboration.” did. Last week, the company recalled its Pixy selfie drone due to the risk of fire due to battery overheating.

An Explanation from a Doctor on How Diabetes Can Be Effortlessly Reversed and Prevented

Imagine your body as a big sugar bowl. At birth, the bowl is empty. Over decades of eating sugar and refined carbohydrates, your bowl gradually fills up. And the next time you eat, the bowl is already full, so the sugar comes in and spills over the sides of the bowl.

The same situation exists in your body. When you eat sugar, your body secretes the hormone insulin to move the sugar into your cells, where it is used for energy. If we don’t burn enough sugar, after a few decades our cells will be completely full and we won’t be able to process it anymore.

The next time you eat sugar, insulin can’t push any more sugar into the overflowing cells, so it floods into your bloodstream. Sugar moves through the blood in a form called glucose, and too much of it (known as hyperglycemia) is the main symptom of type 2 diabetes.

When there’s too much glucose in the blood, insulin doesn’t seem to be doing its normal job of moving sugar into cells. Then you say your body has become insulin resistant, but it’s actually not the insulin’s fault. The main problem is that the cells are flooded with glucose.

High blood sugar is only part of the problem. Not only is there too much glucose in the blood, there is too much glucose in every cell. Type 2 diabetes is an overflow phenomenon that occurs when there is too much glucose throughout the body.

In response to excess glucose in the blood, the body secretes more insulin to overcome this resistance. This forces more glucose into the flooded cells to keep blood levels normal.

This works, but the effect is only temporary because it doesn’t address the problem of excess sugar. The excess was transferred from the blood to the cells, only worsening insulin resistance. At some point, your body can no longer push glucose into your cells, no matter how much insulin you increase.

read more:

What happens in the body if excess glucose is not removed? First, your body continues to produce more insulin to try to get more glucose into your cells. However, this only creates further insulin resistance, creating a vicious cycle.

When insulin levels can no longer keep up with the increased resistance, blood sugar levels spike. At this point the doctor is likely to diagnose her with type 2 diabetes.

Doctors may prescribe drugs such as insulin injections or a drug called metformin to lower blood sugar levels, but these drugs do not rid the body of excess glucose. Instead, they simply continue to take glucose from the blood and return it to the body.

It can then be carried to other organs such as the kidneys, nerves, eyes, and heart, where it can eventually cause other problems. Of course, the fundamental problem hasn’t changed.


Remember that bowl full of sugar? It’s still around. Insulin simply moves glucose from the visible blood into the invisible body. So the next time you eat, sugar will flood back into your bloodstream and you’ll end up injecting insulin to stuff it into your body.

The more glucose your body is willing to accept, the more insulin it needs to overcome its resistance to it. But as the cells swell more and more, this insulin only creates more resistance.

If you exceed the amount your body can produce naturally, drugs can take over. At first, you only need one type of medicine, but eventually the amount of medicine increases to two or three.

And the problem is that diabetes actually gets worse when you increase the amount of medication you take to keep your blood sugar levels at the same level.

Type 2 diabetes is reversible and preventable without drugs

Once you understand that type 2 diabetes is simply too much sugar in your body, the solution is obvious. Remove sugar. Don’t hide it. Let’s get rid of it. There are really only two ways to accomplish this.

  1. Please add less sugar.
  2. Burn off the remaining sugar.

that’s it. That’s all you need to do. The best part? All natural and completely free. No drugs. No surgery. No cost.

Step 1: Reduce the amount of sugar

The first step is to eliminate all sugar and refined carbohydrates from your diet. Added sugar has no nutritional value, so it’s safe to limit your intake. Complex carbohydrates, which are simply long chains of sugar, and highly refined carbohydrates, such as flour, are quickly digested into glucose.

The best strategy is to limit or eliminate bread and pasta made from white flour, as well as white rice and potatoes.

Protein intake should be kept moderate rather than high. When proteins such as meat are digested, they are broken down into amino acids. Adequate protein is necessary for good health, but excess amino acids cannot be stored in the body, so they are converted into glucose in the liver. Therefore, consuming too much protein adds sugar to your body. Therefore, highly processed and concentrated protein sources such as protein shakes, protein bars, and protein powders should be avoided.

What about dietary fat? Natural fats, found in avocados, nuts, and olive oil, which are key components of the Mediterranean diet, have little effect on blood sugar or insulin, and are well-known for their health benefits against both heart disease and diabetes. Masu. Eggs and butter are also good sources of natural fats.

It has been proven that the cholesterol contained in these foods has no negative effect on the human body. Eating dietary fat does not lead to type 2 diabetes or heart disease. In fact, it’s beneficial because it helps you feel full without adding sugar to your body.

To reduce the amount of sugar you put into your body, stick to natural, unprocessed whole foods. Eat a diet low in refined carbohydrates, moderate amounts of protein, and high in natural fats.

Step 2: Burn off the remaining sugar

Exercise (both strength training and aerobic training) has beneficial effects in type 2 diabetes, but its power to reverse the disease is much less than dietary intervention. And fasting is the easiest and surest way to force your body to burn sugar.

Fasting is just the flip side of eating. If you are not eating, you are fasting. When you eat, your body stores food energy. When you fast, your body burns food energy. And glucose is the most easily ingested food energy source. Therefore, a longer period of fasting allows you to burn stored sugar.

It may sound harsh, but fasting is literally the oldest diet known and has been practiced throughout human history without incident. If you are taking prescription medications, you should seek medical advice.

But the important question is: Will my blood sugar levels drop if I don’t eat? of course. Can you lose weight if you don’t eat? of course. So what’s the problem? I can’t see anything.

A common practice is to fast for 24 hours two to three times a week to burn off sugar. Another common approach is fasting for 16 hours five to six times a week. The secret to reversing type 2 diabetes is now in our hands.

All you need is an open mind to embrace new paradigms and the courage to challenge conventional wisdom.

Understanding ImageFX: A Comprehensive Guide to Google’s New AI Image Generator

Google is lagging behind in artificial intelligence. While OpenAI’s innovative Dall-E AI art image generator was released two years ago, Google only recently released its competing product.

The software, known as ImageFX, is backed by one of the largest technology companies and a substantial amount of data. So how is this data accumulated?

In brief, ImageFX has produced some impressive images that rival the best. But how does it work? Can it be accessed now? And have major problems in the AI art world been solved?

How to use Google ImageFX

Google ImageFX is currently available in countries like the United States, Kenya, New Zealand, and Australia.

If you attempt to access the site in a country like the UK, you’ll see a warning stating, “This tool is not yet available in your country.”

To access it from any of the currently available countries, visit Google’s AI Test Kitchen. Then create an account. Once everything is set up, your new prompt will be ready for use.

Even if you’re not in one of the listed countries, the website is still worth visiting. Google allows you to sign up for notifications about when the platform becomes available in your area.

How good is Google ImageFX?

There’s no denying that Google is late to the game. OpenAI’s Dall-E was released in January 2021, and Midjourney was released a year later. So did Google’s delay pay off in terms of quality?

Two images generated by ImageFX. On the left is a room with an art desk, and on the right is a painting of a vampire – Credit: ImageFX

The images released so far demonstrate that ImageFX is capable of producing content at a very high level. Detailed and contextual, ImageFX is an unsurprisingly capable image generator.

But that’s expected. AI art has made significant progress over the years, and Google’s main competitors are producing similarly high-quality work and have been doing so for much longer.

The significant advantage of ImageFX at the moment is that it’s free (in select countries). Both Midjourney and Dall-E are mainly behind paywalls or restricted services, so it’s worth making the most of ImageFX before any changes.

ImageFX also includes a unique feature called the “Expressive Chip.” This allows users to quickly edit the prompt and try a different search. For example, if you request a portrait of a woman, you can quickly switch this to an abstract, hand-drawn, or even oil painting.

How does it work?

Basically, Google ImageFX works like any other AI art generator. This involves several steps, starting with obtaining an image database large enough for training.

Google has not disclosed the source of its training data, but it likely includes a combination of internal sources, collaborations, and possibly web scraping and user-generated content.

Once the database is built, a model is trained on these images to learn the relationships between the words and visual concepts in the images, possibly through a diffusion model.

These models start with random noise in the image and are refined based on information from both the data and the accompanying text description. By repeating this process, you essentially learn the relationships between words, images, and context.

This training helps ImageFX and other AI image generators understand the prompts asked because it understands what words are associated with the images.

How is it linked to Google Bard?

Google Bard is probably the biggest competitor to the AI chatbot ChatGPT. Google has been working on the chatbot for some time and was released publicly in 2023.

If ImageFX is photography, Bard is understanding words and context. The goal is to combine the two to create the ultimate AI model, similar to OpenAI’s combination of ChatGPT and Dall-E (OpenAI’s image generator).

Google Bard is currently in testing but will soon be fully operational with the recently announced Google Gemini system.

This could theoretically mean a platform that asks models to create a board game and returns both the rules and lore, as well as all images, boards, and content. Or you could write a series of books with illustrations to go along with it.

Does ImageFX produce bad images?

There’s a problem with AI art…people. When trained on artwork from a human population and then utilized again by humans, less appropriate parts of the human brain tend to enter.

Previous AI art generators displayed sexist, biased, and sometimes intensely graphic images. This is a problem that all major technology companies are trying to tackle, including Google with ImageFX.

“All images generated with ImageFX are marked with SynthID, a tool developed by Google DeepMind that adds digital watermarks directly to the content we generate.” Google says:.

“SynthID watermarks are imperceptible to the human eye but can be detected for identification. Additionally, all images contain metadata, so when you encounter an AI-generated image, You can get more information.”

In addition to this, Google announced that it has improved the safety of its training data, reducing problematic output such as violent, offensive, or sexually explicit content. This extends to a reduced ability to create images of real people.

New discoveries from the Webb telescope shed light on the origins of supermassive black holes and galaxies

New insights from the NASA/ESA/CSA James Webb Space Telescope overturn theories about how black holes shape the universe, reversing the classical theory that black holes formed after the first stars and galaxies appeared. It challenges our understanding. In fact, black holes may have accelerated the birth of new stars during the universe's first 50 million years.


This artist's impression shows the evolution of the universe, starting with the Big Bang on the left and continuing with the emergence of the Cosmic Microwave Background. The formation of the first stars ends the Dark Ages of the universe, followed by the formation of galaxies. Image credit: M. Weiss / Harvard-Smithsonian Center for Astrophysics.

“We know that these monster black holes exist in the centers of galaxies near the Milky Way, but now the big surprise is that they were also present at the beginning of the universe, and that they were like building blocks or seeds of early galaxies. It was something,” he said. Professor Joseph Silk, an astronomer at Johns Hopkins University and the Sorbonne Institute of Astrophysics;

“They've really enhanced everything, including giant amplifiers for star formation. This completely overturns what we previously thought was possible, and how galaxies form. It has the potential to completely shake up our understanding of what happens.”

“The distant galaxies observed by Webb in the early universe appear much brighter than scientists expected, revealing an unusually large number of young stars and supermassive black holes.”

“Conventional wisdom holds that black holes formed after the collapse of supermassive stars, and that galaxies formed after the first stars illuminated the dark early universe.”

But the team's analysis suggests that for the first 100 million years, black holes and galaxies coexisted, influencing each other's fate.

“We argue that the outflow of the black hole crushed the gas clouds and turned them into stars, greatly accelerating the rate of star formation,” Professor Silk said.

“Otherwise, it's very difficult to understand where these bright galaxies came from, because they are typically smaller in the early Universe. Why on earth did they become stars so quickly? Do I need to create one?”

“A black hole is a region of space where gravity is so strong that not even light can escape its attraction.”

“Thanks to this force, they generate powerful magnetic fields that cause violent storms, eject turbulent plasma, and ultimately act like giant particle accelerators.”

“This process may be why Webb's detectors found more black holes and brighter galaxies than scientists expected.”

“We can't fully see these ferocious winds and jets so far away, but we know they must exist because many black holes have been seen in the early universe. I am.”

“The huge wind blowing from the black hole crushes nearby gas clouds, turning them into stars.”

“This is the missing link that explains why these first galaxies are much brighter than we expected.”

According to the research team, there were two stages of the young universe.

In the first stage, star formation was accelerated by high-velocity outflow from the black hole, while in the second stage, the outflow slowed down.

“Hundreds of millions of years after the Big Bang, a supermassive black hole magnetic storm caused gas clouds to collapse and new stars to form at a rate far exceeding that observed in normal galaxies billions of years later,” Professor Silk said. Ta.

“These powerful outflows moved into energy conservation states, reducing the amount of gas available to form stars within the galaxy, thus slowing star formation.”

“We originally thought that galaxies formed when giant gas clouds collapsed,” Professor Silk said.

“The big surprise was that there was a seed in the middle of that cloud, a large black hole, that helped rapidly turn the inside of that cloud into a star at a much faster rate than we expected. So the first galaxies are incredibly bright.”

Argentina Unearths New Species of Titanosaurus from Cretaceous Era

A genus and species of sauropod, a titanosaur mimicking rebachisaurid, measuring over 15 meters (50 feet) in length, has been unearthed in Patagonia, Argentina.



rebuilding the life of Inawentu Osratus. Image credit: Gabriel Rio.

The newly discovered dinosaur roamed the Earth during the late Cretaceous period, about 86 million years ago.

dubbing Inawentu Osratusthe animals were of the following types: titanosaurusa diverse group of long-necked sauropods that lived from the Late Jurassic period (163.5 million to 145 million years ago) to the end of the Cretaceous period (145 million to 66 million years ago).

They are known for their large body size, long necks, and wide stance, and include species ranging from the largest known land vertebrates to “dwarfs” as large as elephants. Some species had osteoderm (armor plate).

“During the late Mesozoic Era, sauropod dinosaurs constituted the main herbivores in all terrestrial ecosystems of polar Gondwana,” said paleontologist Leonardo Filippi of Argentina's Municipal Museum of Urquiza and his colleagues.

“Quadrupedal locomotion and a gravitational posture, a proportionately small cranio-body ratio, and a common bow plan consisting of a series of elongated necks and tails made sauropods capable of large size, locomotion, defense, physiology, and feeding. They have evolved a variety of notable adaptations related to food and behavior.”

“They represented, in terms of diversity and abundance, the major medium- to large-sized herbivore component of the fauna in most of these southern landmass.”

partially completed specimen Inawentu Osratus It was recovered from fluvial deposits at the La Invernada archaeological site, part of the Bajo de la Carpa Formation in the Neuquen Basin of Patagonia, Argentina.

“The recovered human bones were found interlocked within a horizon of massive reddish solidified mudstone covered by a thin layer of sand (30 cm thick) associated with flood deposits of the river bank. ' explained the researchers.

Inawentu Osratus It shows remarkable convergent properties of the skull anatomy. rebatisauridae sauropodaccording to the author.

Inawentu Osratus “It belongs to the square-jawed titanosaur clade and was restricted to the final stages of the Late Cretaceous of South America,” the researchers said.

“The discovery of new materials and different datasets providing new morphological information allows us to provide better support in future phylogenies confirming the existence of this square-jawed titanosaur clade. Become.”

Inawentu Osratus And perhaps other members of this clade have obvious nutritional adaptations seen in preceding rebatisaurid sauropods, such as broad snouts and relatively short necks. ”

“In this connection, a series of shortened cervix Inawentu Osratus This may be consistent with low browsing feed behavior. ”

“This could have paleoecological implications, such as a zoological alternation in the Gondwanan ecosystem since the Turonian period or a low-browsing diet in two distinct lineages of sauropod dinosaurs.”

Neuroscientist Luana Colloca aims to revolutionize pain treatment through the power of the placebo effect

Clove Jetsy; Fierce: Matthew Paul D'Agostino

Despite being a phenomenon known for hundreds of years, there is still much to learn about the placebo effect, which improves health after receiving dummy treatments like sugar pills. It is thought that behind this is the expectation of a positive outcome, and that negative expectations are responsible for the opposite undesirable phenomenon, the nocebo effect, which worsens symptoms. But questions remain about how the mind influences the body in this way and why some people feel its influence more strongly than others.

Luana Colloca are among those grappling with such questions. Colloka, a neuroscientist and director of the Placebo Beyond Opinion Center at the University of Maryland School of Nursing in Baltimore, and colleagues have shown how certain genetic variations shape the extent to which a person responds to a placebo. Ta. They are now studying how best to harness such effects to relieve pain, which could reduce the use of prescription opioid drugs and the risk of addiction to them. They are also exploring the use of virtual reality, with results published last year showing that virtual reality can effectively reduce levels of perceived pain and anxiety.

This robot can autonomously unlock nearly any door.

A wheeled robot released on a college campus has discovered how to roll around the real world and open all kinds of doors and drawers.

Robots have adapted themselves to new challenges, paving the way for machines that can independently interact with physical objects. “We want the robots to be able to operate autonomously, without having to rely on humans to keep giving them examples of all new kinds of scenarios during testing,” he says. Deepak Pathak at Carnegie Mellon University (CMU) in Pennsylvania.

Pathak and his colleagues initially trained the robot through imitation learning, which provided visual examples of how to open objects such as doors, cabinets, drawers, and refrigerators. They then unleashed it around CMU's campus, opening doors and cabinets they had never encountered before. This required the robot to adapt to each new object using artificial intelligence that rewards the robot for understanding things.

The robot typically spent 30 minutes to an hour learning how to open each object consistently. Haoyu Shion CMU Ph.D. built a robot to scout various testing locations on campus. The team included his 12 training objects for practice, and then he included eight additional objects to test the robot's abilities.

Initial success rates averaged about 50%, but the robot sometimes completely failed to open new objects when first started. Eventually, that success rate increased to about 95%.

In addition to learning on the fly, he said he had to be able to physically handle heavy doors. Russell Mendonca At C.M.U. Achieving both goals will cost him $25,000, which he says is much cheaper than other robotic systems with adaptive learning capabilities.

Demonstrating the robot outside the lab “represents a concrete step towards more general robotic manipulation systems,” he said. Yunju Lee At the University of Illinois at Urbana-Champaign. “Opening a door or a drawer is a seemingly simple task for humans, but it's actually surprisingly difficult for robots,” he says.

Gemini South Telescope zeroes in on unusual lenticular galaxy NGC 4753

NGC 4753’s remarkable and complex network of dust lanes winding around its galactic core defines its “peculiar” classification, and was probably the result of the galaxy’s merger with a nearby dwarf galaxy about 1.3 billion years ago. It is thought that there is.



This image from the Gemini South Telescope, one half of the International Gemini Observatory operated by NSF’s NOIRLab, shows NGC 4753, a lenticular galaxy about 60 million light-years away in the constellation Virgo. Image credits: International Gemini Observatory / NOIRLab / NSF / AURA / J. Miller, International Gemini Observatory and NSF’s NOIRLab / M. Rodriguez, International Gemini Observatory and NSF’s NOIRLab / M. Zamani, NSF’s NOIRLab.

NGC4753 is a lenticular galaxy located approximately 60 million light-years away in the constellation Virgo.

This galaxy, also known as LEDA 43671, UGC 8009, and IRAS 12498-0055, discovered It was proposed by German-born British astronomer William Herschel on February 22, 1784.

NGC 4753 is a member of the NGC 4753 group of galaxies in the Virgo II cloud, a series of at least 100 galaxy clusters and individual galaxies that extend away from the southern edge of the Virgo Supercluster.

“There is an astonishing number of galaxies in the observable universe, with recent estimates putting the number between 100 billion and 2 trillion,” Gemini astronomers said in a statement.

“And just like snowflakes, no two are exactly alike. However, they can be divided into four broad classes based on their appearance and physical characteristics: elliptical, lenticular, irregular, and spiral. , with many subclasses in between.”

“However, galaxies are dynamic objects that evolve over time while interacting with their surrounding environment, meaning that an individual galaxy can fall into multiple classifications over its lifetime. ”

In 1992, Indiana University astronomer Tom Steiman-Cameron and colleagues published A detailed study of NGC 4753 reveals that its complex shape is likely the result of a merger with a small companion galaxy.

“Galaxies that swallow other galaxies often look like train wrecks, but this is a train wreck galaxy,” said Dr. Steiman-Cameron.

Galactic mergers occur when two or more galaxies collide, mixing their material and significantly changing the shape and behavior of each galaxy involved.

In the case of NGC 4753, the once-standard lenticular galaxy is thought to have merged with a nearby gas-rich dwarf galaxy about 1.3 billion years ago.

The dwarf galaxy’s gas, combined with the burst of star formation caused by this galactic collision, injected large amounts of dust into the system.

The galaxy’s gravitational inward spiral spread out the accumulated dust into a disk. And this is where the story gets interesting.

Astronomers have discovered that a phenomenon known as differential precession is responsible for NGC 4753’s tangled dust lanes.

Precession occurs when a rotating object changes its axis of rotation, like a spinning top that loses momentum and wobbles. And differential means that the speed of precession is different depending on the radius.

For a dusty accretion disk orbiting around a galactic nucleus, the rate of precession is faster toward the center and slower near the edges.

This fluctuating wobble-like motion is due to the angle at which NGC 4753 and its former dwarf companion collided, and is responsible for the strongly twisted dust lanes that we see today wrapping around the galaxy’s luminescent core. It becomes.

“For a long time, no one knew what to make of this strange galaxy,” said Dr. Steiman-Cameron.

“But by starting with the idea that the accreted material fills the disk and analyzing the three-dimensional geometry, the mystery was solved.”

“Thirty years later, we are now incredibly excited to be able to see this highly detailed image with the Gemini South Telescope.”

Reconsidering Classification: Climate Change’s Impact on Category 6 Hurricanes

Studies have shown that although climate change is not expected to increase the number of hurricanes, rising ocean temperatures will make hurricanes more intense. Warmer atmosphere can hold more moisture, leading to heavier rainfall and flooding from these storms.

Therefore, as long as global warming continues, we can expect more intense storms on Earth.

Researchers found that from 1980 to 2021, five storms in the past nine years had maximum wind speeds exceeding 192 miles per hour, which could have been classified as Category 6 storms. Their study also used models to explore how different climate scenarios could affect hurricanes and other large storms around the world. They found that if the Earth warmed by 2 degrees Celsius above pre-industrial levels, the risk of Category 6 storms could double in the Gulf of Mexico and in Southeast Asia and the Philippines.

The researchers also highlighted that even the relatively low global warming target of the Paris Agreement, aiming to limit global warming to 1.5 degrees Celsius, could significantly increase the likelihood of Category 6 storms.

These findings will continue the debate about how to better communicate the threat of extreme weather events and how climate change increases that threat. For example, scientists pointed out that the Saffir-Simpson hurricane scale cannot convey some of the most destructive aspects of hurricanes, such as storm surge, rainfall, and flooding. Adding a sixth category to the Saffir-Simpson hurricane wind scale may raise awareness of the increased risk of major hurricanes due to global warming. The National Hurricane Center has also announced new experimental forecasts to better communicate the risk of inland winds during extreme weather events.

Ancient Fossils of Land-Dwelling Animals Found in Australia Dating Back 380 Million Years

Paleontologist at Flinders University brian chu and his colleagues described a new genus and species of Devonian tetrapod fish based on several nearly complete skulls and postcranial skeletons.

Tetrapodomorpha “It consists of tetrapods and their closest fish relatives, the oldest records of which are from the Pragians of China,” said Dr Chu and co-authors.

“This group diversified greatly in both marine and freshwater habitats during the Middle to Late Devonian, giving rise to several distinct lineages, including the earliest quadrupeds.”

“Tetrapods flourished after the Devonian limbless fish tetrapods experienced a marked decline in diversity during the Carboniferous, but only survived into the early Permian before disappearing from the fossil record. There were only a handful of representative animals.”

This new species of tetrapod lived about 380 million years ago and was up to 45 to 50 centimeters long.

with scientific name Harajikadectes zuminithis fish is particularly distinctive for its large opening at the top of its skull.

“These spire-like structures are thought to facilitate air breathing at the surface, and modern African bichir fish have similar structures for taking in air at the surface,” said Dr Chew. Ta.

“This feature appears in multiple tetrapomodorf lineages at about the same time during the middle to late Devonian period.”

“In addition to Harajikadectes zumini Large spiracles also appeared from central Australia. gogonathus El Pisto Stegarian from Western Australia Tiktaalik — are the closest relatives of four-limbed quadrupeds. ”

“And it shows up in unrelated places.” Pickeringius Western Australian stingray fin fish first described in 2018. ”

Professor John Long from Flinders University said: “This synchronous emergence of air-breathing adaptations may have coincided with a period of reduced atmospheric oxygen during the mid-Devonian.”

“The ability to supplement gill breathing with oxygen from the air may have provided an adaptive advantage.”

“We discovered this new form of lobe-finned fish in one of the most remote fossil sites in all of Australia, the Harajika Sandstone Formation in the Northern Territory, about 200km west of Alice Springs. It dates from the mid-Devonian period. Late period, approximately 380 years ago.'' 1 million years old. ”

“It's difficult to pinpoint the location. Harajikadectes zumini sit in this group of fishes because they appear to have convergently acquired a mosaic of specialized features characteristic of widely separate branches of the tetrapod radiation. ”

Meta cracks down on deceptive content by pushing for labeling of all AI images on Instagram and Facebook

Meta works to identify and label AI-generated images on Facebook, Instagram, and Threads, and is striving to expose “people and organizations that actively seek to deceive the public.” Masu.

Images created using Meta’s AI image tools are already labeled as AI, but Nick Clegg, the company’s global president, stated in a blog post on Tuesday that the company’s competing services will start labeling AI-generated images.

Meta’s AI images already have metadata and an invisible watermark indicating that the image was created by AI. The company has partnered with Google, OpenAI, Microsoft, Adobe, Midjourney, and Shutterstock to work on AI image generators, according to Clegg.

Clegg said, “As the line between human content and synthetic content becomes blurred, people want to know where the line is.”

He added, “People often encounter AI-generated content for the first time, and our users appreciate the transparency around this new technology. It’s important to let people know that it was created using AI.”

A surfing llama or an AI? Image labels for AI-generated content on Facebook.

Clegg mentioned that the labeling feature is being developed and will be rolled out to all languages in the coming months.

He also stated that the company will add more prominent labels on images, videos, or audio that are “digitally created or altered” and “have a particularly high risk of materially misleading the public.”

Additionally, the company is working to develop technology to automatically detect AI-generated content, even when the content lacks invisible markers or has been removed.

“This work is particularly important because the online space is likely to become increasingly hostile in the coming years,” Mr Clegg said.

He concluded, “People and organizations actively trying to deceive people with AI-generated content will find ways to circumvent the safeguards in place to detect it. Our industry and society as a whole must continue to find ways to stay ahead of the curve.”

AI deepfakes have already become an issue in the US presidential election cycle, with examples of AI-generated deepfakes used to dissuade voters in the New Hampshire Democratic primary.

Australia’s Nine News also faced criticism for altering an image broadcast on the evening news that exposed Victorian Animal Justice Party MP Georgie Purcell’s belly button and altered her chest, using Adobe’s AI image tools.

Why the UK is Delaying AI Regulation: Exploring the Lack of Rush in Legislation

BRetain wants to lead the world in AI regulation. However, AI regulation is a rapidly evolving and contested policy area, with little agreement on what a good outcome looks like, let alone the best way to get there. And the fact that he is the third most important AI research center in the world does not give him so much power if the first two are the United States and China.

How do we cut this Gordian knot? Simple: Act quickly and decisively and do nothing.

The UK Government has today taken the next step towards legislation to regulate AI. From our story:

The government will admit on Tuesday that binding measures to oversee
cutting-edge AI development will be needed at some point, but not immediately. Instead, ministers will set out “initial thoughts on future binding requirements” for advanced systems and discuss them with technical, legal and civil society experts.

The Government will also give regulators £10m to help tackle AI risks and require them to develop their approach to the technology by April 30th.

When the first draft of the AI ​​whitepaper was published in March 2023, the reaction was negative. The government’s proposal was withdrawn on the same day as the now-infamous call for a six-month “pause” on AI research to control the risks of an out-of-control system. Against this background, this white paper seemed pathetic.

The proposal would give regulators no new powers and would not give responsibility for guiding AI development to any private group. Instead, the government planned to align existing regulators, such as the Competition and Markets Authority and the Health and Safety Executive, and set out five principles to guide the regulatory framework when considering AI.

This approach has been criticized by the UK’s leading AI research group, the Ada Lovelace Institute, as having “significant gaps”, and even the fact that a multi-year legislative process will leave AI unregulated during the interim period. Ignored.

So what has changed?Well, the government Really awesome £10 million

Asking regulators to “upskill”
, has set an April 30 deadline for the largest companies to publish their AI plans. A Department for Science, Innovation and Technology spokesperson said: “The UK Government is in no hurry to legislate and will not risk introducing ‘ready-to-read’ rules that quickly become outdated or ineffective.” Ta.

This is a strange definition of “global AI leadership” and it’s important to immediately say “we’re not doing anything.” The government is also “considering” actual regulations, envisioning “future binding requirements that may be introduced for developers building cutting-edge AI systems.”

The second, slightly larger fund will cost “almost” £90m to launch “nine new centers of excellence across the UK”. The government also announced £2 million in funding to support “new research projects that help define what responsible AI looks like”.

There is an element of tragedy when reading the government press release that triumphantly revealed £2 million in funding from Yoshua Bengio, one of the three “godfathers” of AI, just a week later.
Asks Canada to spend $1 billion We are building publicly owned supercomputers to keep up with the big tech companies. It’s like bringing a spoon to a knife fight.

You can say you’re agile in the face of conflicting demands, but after more than 11 months, it just seems impossible to commit. The day before the latest update to the AI ​​White Paper was published, the Financial Times broke the news that another pillar of AI regulation had collapsed.
from that story (lb):

The Intellectual Property Office, the UK government’s agency that oversees copyright law, is working with AI companies and rights holders to produce guidance on text and data mining, where AI models are trained on existing materials such as books and music. We are discussing with.

But a group of industry executives convened by the IPO to oversee the work was unable to agree on a voluntary code of conduct, handing responsibility back to officials at the Department of Science, Innovation and Technology.

Unlike broader AI regulation, which has a quagmire of conflicting opinions and very vague long-term goals, copyright reform is a very clear trade-off. On the one hand, creative and media companies that own valuable intellectual property. On the other side are technology companies that can use their intellectual property to build valuable AI tools. One group or the other will be frustrated by the outcome. A perfect compromise simply means that both are true.

Last month, the head of Getty Images was one of many to call on the UK to support its creative industries, which make up a tenth of the UK economy, citing the theoretical benefits that AI could bring in the future. And, faced with difficult choices with no right answers, the government chose to do nothing. Then you cannot lead the world in the wrong direction. And isn’t that what leadership is all about?

To be fair to the government, there are obvious problems with moving too quickly. Let’s take a look at social media to see some of them. Facebook’s rules do not prohibit deepfake videos of Joe Biden, the company’s Oversight Board (also known as the “Supreme Court”) has found.But honestly, it’s not clear what they are do Prohibition will become increasingly problematic. From our story:

Skip past newsletter promotions

Meta’s oversight board found that a Facebook video that falsely suggested that U.S. President Joe Biden is a pedophile did not violate the company’s current rules, but said the rules were “disjointed”. Yes, we believe that the focus is too narrow on AI-generated content.

The board, which is funded by Facebook’s parent company Meta but operates independently, took over the Biden video case in October in response to user complaints about a doctored seven-second video of the president.

Facebook rushed out a “manipulated media” policy several years ago, before ChatGPT and large-scale language models became AI trends, and amid growing interest in deepfakes. The rule
s prohibited misleading and altered videos created by AI.

The problem, the oversight committee said, is that the policy is impossible to apply because it has little clear rationale behind it and no clear theory of the harm it seeks to prevent. How can moderators differentiate between videos created by AI (which is prohibited) and videos created by skilled video editors (which are allowed)? Even if they could, Why is only the former problematic enough to be removed from the site?

The Oversight Committee proposed updating the rules to remove the temporary reference to AI altogether and instead require labels to identify manipulated audio and video content, regardless of the manipulation method. Mehta said it would update its policy.

Brianna Gee’s mother is calling for a revolution in how teens approach social media after her daughter was murdered by two of her classmates. Under-16s, she says, should be limited to devices made for teenagers that allow parents to easily monitor their technological lives, which are age-restricted by governments and tech companies.

I spoke to Archie Brand, editor of the daily newsletter First Edition, about her plea:

This lament will resonate with many parents, but in Brianna’s case it has special power. She was “secretly accessing sites on her smartphone that promoted anorexia and self-harm.”
Petition created by Esther Say. And prosecutors
said her killers used Google to search for poisons, “serial killer facts” and ways to combat anxiety, and searched Amazon for rope.

“We don’t need new software to do everything Esther Gee wants us to do,” says Alex Hahn. “But there’s a broader problem here. Just as this sector has historically moved faster than governments can keep up, it’s also moving faster than parents can keep up. This varies from app to app and changes regularly, so it’s a large and difficult job to keep track of.”

Study shows the world’s happiest people don’t reside in Scandinavia

Consider the happiest country in the world. Are you thinking of somewhere in Scandinavia? Well, a new study has brought to light something that may have been overlooked. They are actually the happiest people in the world, but they are often not included in rankings.

In global happiness rankings, such as the World Happiness Report (WHR), researchers typically note a correlation between high levels of life satisfaction and high incomes. However, these rankings often fail to differentiate between small indigenous groups and the overall population of a nation. In some of these communities, money has a minimal impact on daily life and livelihoods.

A new paper suggests that not all happiness is tied to money. In fact, it turns out that some low-income societies, particularly those that rely on nature rather than money, exhibit significantly higher life satisfaction and may even be some of the happiest people in the world.

“The frequently observed strong correlation between income and life satisfaction is not universal and proves that the wealth generated by developed economies is not fundamentally necessary for humans to live happy lives.” – Professor Victoria Reyes Garcia, senior author of the study


Who is the happiest person in the world?

Although not conducted by the same research institute as WHR, this new study was published in the journal Proceedings of the National Academy of Sciences (PNAS) and measured happiness in a similar way. The WHR asks respondents to imagine a ladder with 10 being the best life and 0 being the worst, and then evaluate their life on that scale.

In this study, researchers translated the question into local languages: “Taking all aspects into consideration, how satisfied are you with your life on a scale of 0 to 10?”

The research team collected responses from 2,966 people from 19 indigenous and local communities around the world. Only 64 percent of households surveyed in these communities had any cash income.

These 19 communities had an average score of 6.8, with the lowest score being 5.1. However, four of these communities scored above 8/10 and, if included in the WHR, these small societies would be among the happiest people in the world. In 2023, WHR found that the countries with the highest scores were Finland (7.8), Denmark (7.6), and Iceland (7.5).

The highest scores were reported in Latin America, despite many of these societies having suffered from histories of marginalization and oppression, according to the authors.

Researchers say the findings are positive news for sustainability in the face of climate change, as this research suggests that people can achieve high levels of happiness without the need for resource-intensive economic growth.

They encourage future research to examine specific factors that influence well-being in societies where money is not central, such as family and social support, spirituality, and connection to the natural world.

Court Rejects Craig Wright’s Claim of Inventing Bitcoin as a “Brazen Lie”

The High Court has heard that an Australian computer scientist’s claim to be the author of Bitcoin’s founding documents is a “blatant lie”. Craig Wright, a 53-year-old who claims to be the pseudonymous author Satoshi Nakamoto, is being sued by a group of cryptocurrency exchanges and developers, with Twitter founder Jack Dorsey’s Crypto Patent Alliance (Copa) seeking a “negative declaration” that Wright is not Nakamoto.

The President of Copa, Jonathan Hough KC, told the High Court that Wright’s claims were “a brazen lie and an elaborate false narrative backed by industrial-scale fabrications.” Hough also mentioned that elements of Wright’s conduct, including his alleged use of ChatGPT to create fabrications to support his claims, were reminiscent of a “farce”. These claims, according to Hough, have “deadly serious” consequences for individuals who faced litigation based on Wright’s claims. He stated, “Dr. Wright has consistently failed to provide genuine evidence that he is Satoshi. Instead, he has repeatedly presented documents that clearly show signs of falsification.”

Both experts agreed that the original white paper was written in OpenOffice software, while the version Wright provided was created using software called LaTeX. Additionally, Wright’s claims to be Satoshi are met with widespread skepticism within the crypto community. Mr Wright’s barrister, Lord Grabiner KC, stated that he published the white paper after “spending many years researching and researching the concepts underlying Bitcoin” and has a “rare combination of interdisciplinary talent” and extensive experience in the field, which Nakamoto has “uniquely brought together” in the white paper.

The trial before Judge Mellor is scheduled to begin with Wright testifying on Tuesday and is expected to conclude next month with a written judgment expected at a later date.

Unique Crown Shapes of Early Carboniferous Tree Species

Sanphodiacaulis densifolia is an extinct tree species that existed in what is now New Brunswick, Canada, between 359 and 347 million years ago (Carboniferous period). The structure consisted of an unbranched 16 cm diameter trunk and compound leaves arranged in a 13 cm spiral and compressed to a vertical trunk length of 14 cm. The compound leaves in the upper 0.75 m of the trunk were over 1.75 m long, with preserved alternating secondary collaterals starting 0.5 m from the trunk. In the lower region of the trunk there were only persistent leaf bases. Sanphodiacaulis densifolia shows that the early Carboniferous vegetation was more complex than expected, indicating that this was an experimental, perhaps transitional, period of diverse growth structures.

Trees first appeared during the Middle Devonian period (393 to 383 million years ago), but modern woody plants did not appear until about 10 million years later.

Evidence for dendritic structures (tree-like structures) is primarily based on mud moldings, sand moldings, or calcified stumps, or extensive root structures in fossilized soils.

Under unique preservation conditions, these early trees fossilized with roots and crown structures attached to their trunks.

“The method is Sanphodiacaulis densifolia “It has very long leaves around its slender trunk, and it's amazing how many leaves there are on such a short trunk,” said Dr. Robert Gastaldo, a paleontologist at Colby College. he said.

“The morphology of these 350-million-year-old trees looks like ferns or palms, even though palms arose 300 million years ago.”

“However, the functional leaves of ferns and palm trees are clustered at the top and are relatively few in number.”

“in contrast, Sanphodiacaulis densifolia More than 250 leaves have been preserved around the trunk, with each partially preserved leaf extending 1.75 meters from the trunk. ”

“We estimate that each leaf grew at least another meter before it finished.”

“This means that ‘bottlebrush’ had a dense canopy of leaves that were not woody and spread for at least 5.5 meters around a trunk that was only 16 cm in diameter. Amazing to say the least. .”

Dr. Gastaldo and his colleagues examined five fossil specimens. Sanphodiacaulis densifolia.

The fossil was excavated from the Sanford Quarry, part of the Albert Formation in New Brunswick, Canada.

“These fossils were preserved when an earthquake destroyed trees and other vegetation along the edge of a rift lake,” Gastaldo said.

“The first fossil wood was unearthed from a quarry about seven years ago, but it contained only one partial sample.”

“It took several years to find four other specimens of the same plant in close spatial proximity.”

“One of the specimens reveals how the leaves separate from the top of the tree, which makes this tree quite unique.”

“This is one of the few preserved trunks with crown leaves still attached in a fossil record spanning more than 400 million years.”

Sanphodiacaulis densifolia It probably relied on its unusual growth form to maximize the amount of light it could capture and reduce competition with other plants above ground.

This discovery provides important insights into the evolution of plants and arboreal growth, that is, plants that grow to the height of a tree, or at least 4.5 m, at maturity.

They also remind us that throughout the history of life on Earth, there have been trees that look like nothing we've ever seen before.

“We all have a mental concept of what a tree looks like, depending on where we live on the planet, and we all have a vision of something familiar,” Dr. Gastaldo said. Ta.

“The fossils we report are unique and represent some of the strangest growth forms in the history of life.”

“This is an evolutionary experiment during a period of forest plant biodiversity, and it appears to be a short-lived form.”

“The history of life on land consists of plants and animals that are different from those that live today,” he added.

“The evolutionary mechanisms that operated in the distant past allowed organisms to survive for long periods of time, but their shape, morphology, growth structure, and life history followed different trajectories and strategies.”

“Rare and unusual fossils like the New Brunswick tree are just a few examples of failed experiments that have colonized our planet.”

Viral Video of Tesla Driver Using VR Headset Prompts US Government Alert

U.S. Transportation Secretary Pete Buttigieg said on Monday that human drivers should always use caution after videos surfaced of people driving Teslas wearing what appears to be Apple’s recently released Vision Pro headset. He said he needed to pay.


Buttigieg responded on Twitter/X to a video that has been viewed more than 24 million times that shows a Tesla driver seemingly gesturing with his hands to manipulate a virtual reality field.

Buttigieg said on Monday that Tesla’s self-driving assist features (Autopilot, Enhanced Autopilot, Full Self-Driving), despite their names, do not mean the vehicle is fully self-driving. said on social media.

“Be careful – all advanced driver assistance systems available today require a human driver to be in control and fully engaged in the driving task at all times,” Buttigieg said.

Apple’s Vision Pro was released last week and blends three-dimensional digital content with views of the outside world. Apple, which says it should never be used while operating a moving vehicle, did not respond to a request for comment.

— Secretary Pete Buttigieg (@SecretaryPete) February 5, 2024


According to Apple’s Alan Dye, the Vision Pro will work as a headset that allows users to interact with “apps and experiences” in an augmented reality (AR) version of their surroundings or in a fully immersive virtual reality (VR) space. Vice President of Human Interface Design announced in June.

“Apple Vision Pro relies solely on your eyes, hands, and voice,” Dai said in June. “Browse your system just by looking. App icons come to life when you look at them. Just tap your fingers at the same time to select them and scroll them with a light flick.”

“Apple Vision Pro will change the way we communicate, collaborate, work, and enjoy entertainment,” said Apple executive Tim Cook. But the company didn’t intend for Vision Pro to change the way people commute.

Tesla did not immediately respond to a request for comment.

Buttigieg previously made similar comments about Tesla’s use of Autopilot. Tesla says its advanced driver features are intended for use by fully alert drivers who “keep their hands on the wheel and ready to take over at any time.”

Close-up of Arp 140 captured by Hubble Space Telescope

The NASA/ESA Hubble Space Telescope has captured an excellent image of the interacting spiral lens galaxy pair Arp 140.

Alp 140 Located approximately at 70 million light years Beyond Cetus.

This galaxy duo Atlas of unique galaxiesA catalog of 338 galaxies compiled in 1966 by American astronomer Halton Earp.

It consists of NGC274 (also known as LEDA 2980) and NGC275 (LEDA 2984).

NGC 274 is classified as a lenticular galaxy, and NGC 275 is classified as a barred spiral galaxy.

“Lentiform galaxies and barred spiral galaxies have different structures,” Hubble astronomer explained.

“In a barred spiral galaxy, a bar of stars runs through the galaxy's central bulge (seen here as a bright white vertical haze in NGC 275).”

“Typically, the arms of a galaxy begin at the end of the bar.”

“Lentiform galaxies, on the other hand, fall between elliptical and spiral galaxies,” the researchers added.

“Its name comes from its edgy appearance, which resembles a saucer.”

“Lenticular galaxies have a large central bulge and a flat disk-like spiral, but no spiral arms.”

“It doesn’t have much gas or dust, and it’s mainly made up of old stars.”

Previous observations of Arp 140 revealed a tidal tail extending light-years from NGC 275 beyond the interacting pair.

They also showed that, contrary to the often assumed picture of interacting galaxies, NGC 275 does not exhibit enhanced star formation.

Super-Earth exoplanet found within habitable zone of TOI-715 by astronomers

Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS), astronomers discovered a habitable zone planet orbiting nearby red dwarf star TOI-715 every 19.3 days and characterized its characteristics. I made it clear. They also demonstrated that a second, smaller exoplanet with a period of 25.6 days may exist, located just inside the outer edge of TOI-715’s habitable zone. This system represents the first of his TESS discoveries to fall within this most conservative and widely applicable habitable zone.



Artist’s impression of the super-Earth exoplanet TOI-715b. Image credit: NASA/JPL-Caltech.

TOI-715 is an M dwarf star of spectral type M4 located approximately 137 light-years away in the constellation Urae.

The star, also known as TIC 271971130, is about 6.6 billion years old, making it older than the Sun.

TOI-715 includes the super-Earth exoplanet TOI-715b and the smaller terrestrial exoplanet candidate TOI-715c.

“TOI-715b is about 1.5 times wider than Earth and orbits within the habitable zone around its parent star,” said Georgina Dransfield, an astronomer at the University of Birmingham.

“This is the distance from the star that can give the planet the right temperature for liquid water to form on its surface.”

“Of course, for surface water to exist, several other factors have to be in place, especially for us to have a suitable atmosphere.”

“However, the conservative habitable zone (which may be narrower and more robustly defined than the broader ‘optimistic’ habitable zone) is a It ranks first.”

“A smaller planet, TOI-715c, may be only slightly larger than Earth and may exist just inside the conservative habitable zone.”

“TOI-175b joins the list of habitable zone planets that could be scrutinized more closely by Webb, perhaps also for atmospheric signatures,” the astronomers said.

“A lot depends on other properties of the planet, such as how heavy it is and whether it can be classified as a water world. Its atmosphere, if any at all, is more massive, denser, and has an atmosphere. It’s less pronounced than the atmosphere, and much less difficult to detect. Drier worlds are likely to keep their inconspicuous atmospheres close to the surface.”

“If the possibility of a second Earth-sized planet in this system is confirmed, it would be the smallest habitable zone planet ever discovered by TESS.”

“This discovery also exceeds TESS’s initial expectations by discovering an Earth-sized world within the habitable zone.”

This finding is reported in the following article: paper inside Royal Astronomical Society Monthly Notices.
