There is concern among geologists regarding the development of the GeoGPT chatbot, supported by the International Union of Geological Sciences (IUGS). They worry about potential Chinese censorship or bias in the chatbot.
Targeting geoscientists and researchers, especially in the Southern Hemisphere, GeoGPT aims to enhance the understanding of geosciences by utilizing extensive data and research on the Earth’s history spanning billions of years.
This initiative is part of the Deeptime Digital Earth (DDE) program, established in 2019 and primarily funded by China to promote international scientific cooperation and help countries achieve the UN’s Sustainable Development Goals.
One component of GeoGPT’s AI technology is Qwen, a large-scale language model created by Chinese tech company Alibaba. Geologist and computer scientist Professor Paul Cleverley, who tested a pre-release version of the chatbot, highlighted concerns raised in an article in Geoscientist journal.
In response, DDE principals stated that GeoGPT also incorporates another language model, Meta’s Llama, and disputed claims of state censorship, emphasizing the chatbot’s focus on geoscientific information.
Although issues with GeoGPT have been mostly resolved, further enhancements are underway as the system is not yet released to the public. Notably, geoscience data can include commercially valuable information crucial for the green transition.
The potential influence of Chinese narratives on geoscience-related questions raised concerns during testing of Qwen, a component of GeoGPT’s AI, prompting discussions on data transparency and biases.
Future responses of GeoGPT to sensitive queries, especially those with geopolitical implications, remain uncertain pending further development and scrutiny of the chatbot.
Assurances from DDE indicate that GeoGPT will not be subject to censorship from any nation state and users will have the option to select between Qwen and Llama models.
While the development of GeoGPT under international research collaboration adds layers of transparency, concerns persist about the potential filtering of information and strategic implications related to mineral exploration.
As GeoGPT’s database remains under review for governance standards, access to the training data upon public release will be open for scrutiny to ensure accountability and transparency.
Despite the significant funding and logistical support from China, the collaborative nature of the DDE aims to foster scientific discoveries and knowledge sharing for the benefit of global scientific communities.
Exciting developments are on the horizon in the world of obesity medications.
Pharmaceutical companies are racing to create new drugs, building on the success of existing medications like Novo Nordisk’s Ozempic and Wegovi, as well as Eli Lilly’s Maunjaro and Zepbound.
In addition to targeting diabetes and weight loss, some experimental drugs show promise in improving liver and heart function while reducing common side effects such as muscle loss seen with current treatments. Data on 27 GLP-1 drugs in development will be presented at the 2024 American Diabetes Association meeting in Orlando, Florida.
According to Marlon Pragnell, PhD, the ADA’s vice president of research and science, the pipeline now includes a variety of drug candidates in different stages of development, creating an exciting landscape of innovation.
While most of the data currently available comes from animal studies or early human trials, some drugs may be available in the United States over the counter within a few years, with FDA approval likely further down the line.
As the field of GLP-1 drugs continues to expand, there is hope for more affordable medications with fewer side effects to become available, offering new possibilities for patients.
Exploring Different Hormones for Weight Loss
GLP-1 drugs function by slowing down the digestive process and promoting a sense of fullness. In addition to GLP-1, emerging weight-loss drugs are examining the impact of another hormone called glucagon, which can mimic the effects of exercise.
One such drug, Pemvidutide from Maryland-based Altimmune, combines glucagon with GLP-1 to potentially enhance weight loss effects.
Results from a Phase 2 trial involving obese or overweight adults showed promising weight loss outcomes, paving the way for further research into the drug’s potential benefits.
Altimmune’s Chief Medical Officer, Dr. Scott Harris, highlighted the drug’s ability not only to aid in weight loss but also to provide additional health benefits for liver and heart function while preserving lean body mass.
Altimmune plans to move forward with Phase 3 trials and aims to introduce the drug in the U.S. by 2028.
Competition and Cost Considerations
Having a variety of weight-loss drugs available can help address shortages and potentially drive down costs over time. The high prices of current medications like Wegobee and Zepbound in the U.S. can pose financial challenges for many patients.
Different patients may respond differently to various treatments, as highlighted by Dr. Fatima Cody Stanford of Harvard Medical School. Having a range of options is crucial to tailor treatments to individual needs.
Stay Informed with the Latest News on Weight Loss Drugs
New developments in the pharmaceutical world present opportunities for improved treatment outcomes and potentially life-changing solutions for patients struggling with obesity.
For individuals like Danielle Griffin, who have not seen the desired results from current medications, the prospect of innovative drugs offers hope and excitement for the future.

The Madigen Formation is one of the richest Triassic fossil beds in the world, but few people have ever heard of it.
geo explorers club
About 235 million years ago, in what is now Central Asia, a small reptile fell into a freshwater lake and settled in the soft mud at the bottom.Creatures – named longiskamaIt means “long scales” after the strange feather-like protrusions on its back. It probably lived in the nearby forest, along with many other interesting animals, including a flying reptile known as a flying reptile. Chalovipteryx and Giga Titana giant praying mantis-like insect.
as longiskama's body slowly rotted, gradually turning to stone, continents drifted away, lakes dried up and reformed again and again, and the landscape above changed. Later, in the 1960s, Soviet paleontologist Alexander Sharov discovered reptile fossils. scientifically spotlighted In this little-known corner of the Soviet Union.
Today, the region is located in southern Kyrgyzstan and is a dusty landscape of colorful rock outcrops and dry riverbeds, surrounded by the snow-capped peaks of the Turkestan Mountains. These rocks are the remains of layers of mud and silt that were deposited on the lake bed. longiskama This formation is called the Madigen Formation after a nearby village.Paleontologists recognize it as One of the richest Triassic fossil beds in the world and Lagerstätte –’s site A beautifully preserved specimen – But few others have heard of Madygen.
That's about to change. If all plans go well, this year the region will become the world's first global geopark.
Given the diversity and complexity of endogenous and extrinsic processes that contribute to the maintenance of habitable conditions over geological and biological timescales, it is unclear how rocky planets become habitable and their status. Fully understanding how it is maintained is a fundamental challenge for planetary scientists and astrobiologists. In the face of this challenge, it is essential to exploit the full range of atmospheric evolution data for rocky planets within the solar system. Although Venus represents an apparent fringe member of planetary habitability, its contribution to understanding the prevalence of long-term temperate surface conditions in large rocky worlds remains poorly recognized. Upcoming missions to Venus, including NASA's VERITAS and DAVINCI, and ESA's EnVision mission, will begin to crystallize this understanding.
Kane and Byrne describe Venus as an anchor point where planetary scientists can better understand the conditions that prevent life on exoplanets. Image credit: Kane & Byrne, doi: 10.1038/s41550-024-02228-5.
“We often assume that Earth is a model of habitability, but when we consider this planet in isolation, we don’t know where the boundaries and limits are. Venus gives us that. '' said Dr. Stephen Cain, an astrophysicist at the University of California, Riverside.
“Although they also feature a pressure cooker-like atmosphere that could flatten humans in an instant, Earth and Venus share some similarities.”
“They have roughly the same mass and radius. Given their proximity to the planet, it’s natural to wonder why Earth looked so different.”
Many scientists believe that solar flux, the amount of energy Venus receives from the sun, caused a runaway greenhouse effect that doomed Earth.
“If Earth receives 100% of the solar energy, Venus collects 191%. Many people think that’s why Venus looks different,” Dr. Kane said.
“But wait a minute. Venus doesn’t have a moon, but that gives Earth something like ocean tides and affects the amount of water here.”
In addition to some of the known differences, more NASA missions to Venus will also clarify some of the unknowns.
Planetary scientists have no idea how big its core is, how it arrived at its current relatively slow rotational speed, how its magnetic field has changed over time, or the chemistry of its lower atmosphere. i don’t know.
“Venus has no detectable magnetic field. That may be related to the size of its core,” Dr. Kane said.
“The size of the core also gives us information about how the planet cools. Earth has a mantle, and heat circulates through its core. What’s going on inside Venus? I don’t know.”
“The interior of a rocky planet also influences its atmosphere. That is the case for Earth, and our atmosphere is primarily the result of volcanic gas emissions.”
Schematic cross-section of Earth and Venus. Major internal and atmospheric components are shown to scale. Image credit: Kane & Byrne, doi: 10.1038/s41550-024-02228-5.
NASA is planning two missions to Venus (DAVINCI and VERITAS) for the end of this decade, and Dr. Cain is supporting both.
The DAVINCI mission will explore the acid-filled atmosphere and measure noble gases and other chemical elements.
“DAVINCI measures the atmosphere from top to bottom. This is extremely useful for building new climate models and predicting this type of atmosphere elsewhere, including on Earth, as the amount of carbon dioxide continues to increase. ,” Dr. Kane said.
Although the Veritas mission will not land on the surface, it will allow scientists to reconstruct detailed 3D terrain, which could reveal whether the planet has active plate tectonics or volcanoes.
“Currently, our global map is very incomplete. Understanding how active a surface is and understanding how it has changed over time are very different. We need both types of information,” Dr. Kane said.
Ultimately, Dr. Kane and his co-author, Dr. Paul Byrne of Washington University in St. Louis, advocate such a mission to Venus for two main reasons.
One is that with better data, we can use Venus to confirm that our inferences about life on distant planets are correct.
“The somber thing about searching for life elsewhere in the universe is that we will never have in-situ data on exoplanets. We will never go there, land on them, or measure them directly. I don’t intend to,” Dr. Kane said.
“If we think there is life on the surface of another planet, we may never realize we are wrong and end up dreaming of a planet without life.” I guess.”
“We can only get it right by understanding the Earth-sized planets we can visit. Venus gives us that chance.”
Another reason to study Venus is that it can predict what Earth’s future will be.
“One of the main reasons we study Venus is because of our sacred duty as stewards of this planet to protect its future,” Dr. Kane said.
“My hope is that by studying how Venus came to be today, we can learn lessons from it, especially if it had a benign past that is now in ruins. The question is when and how.”

The curved tip of a wind turbine blade, or winglet, based on the shape of a condor wing
Kashayar Ranamai Vahanbali
A design change inspired by the wings of the Andean condor could increase the energy produced by wind turbines.
Different types of birds have upturned tips at the ends of their wings, which help maximize lift. Similar features, known as winglets, are commonly used on aircraft wings, but have not been tested on the giant turbine blades used to generate electricity.
Kashayar Ranamai Vahanbali Researchers at the University of Alberta in Canada say collecting experimental data on wind turbines with winglets is extremely difficult due to their size.
His team designed a winglet based on the Andean condor, the heaviest flying bird in the world. The Andean condor can travel vast distances, despite weighing up to 15 kg.
Computer simulations of airflow through the turbine showed that these winglets reduced drag and increased efficiency by an average of 10%.
“Another perspective is that the winglets allow the turbine to capture more wind energy with minimal losses. [resistance]” says Ranamayvahanbury.
Winglets can be retrofitted after a turbine is manufactured, he said, by slipping “sock-like” pieces onto the ends of the blades. Researchers are developing an experimental setup to test models of wind turbine winglets.
Peter Majewski, who recently retired from the University of South Australia, said the research results made sense from an engineering and aerodynamics perspective, but retrofitting existing wind turbines would be prohibitive in terms of downtime and cost. He said it might be realistic.
But for new turbine blades, adding winglets during the manufacturing process can lead to significant performance improvements, he says.
Ten years ago, while working as a DJ in Liverpool, England, James Rand would often leave work hearing strange sounds he knew weren't real: high-pitched growls or low-pitched rumblings. . These tinnitus symptoms always went away by the time he woke up… and one day in 2017, they didn't go away.
Doctors confirmed that the sounds were probably caused by Rand's exposure to loud music for hours at a time. There was no cure, no way to get him used to it. “I thought I would never hear silence again,” he says. “He was incredibly depressed.”
But today, the outlook for tinnitus treatment is not so bleak. New research has developed a neurostimulator that reduces the volume of sounds. Additionally, there are several treatments in development that can even stop tinnitus completely. “For the first time, we are discussing potential treatments,” he says. Stéphane Maison at Harvard Medical School.
These insights also shed light on common causes of hearing loss. In fact, they suggest that the same treatments for tinnitus may also restore hearing in people who have become partially deaf due to aging. “The way we think about hearing loss has completely changed,” Maison says.
What is tinnitus?
Tinnitus is one of the most common long-term medical conditions. Affects up to a quarter of older adults. While the crying and rumbling sounds that Rand experiences are common, others may hear whistling, humming, clicking sounds, and even musical hallucinations. Sound can be annoying and distracting, and in some cases can cause depression and anxiety…
Driver abandons car after rainstorm in Dubai, United Arab Emirates, April 17
Christopher Pike/Bloomberg/Getty
Record rainfall has hit the Arabian Peninsula this week, causing flooding in Dubai, Abu Dhabi and other coastal cities in the United Arab Emirates. The extreme weather sparked speculation on social media that the UAE’s long-standing cloud seeding program may have played a role. However, cloud seeding almost certainly does not have a significant impact on flooding.
How unusual was the recent rain in the Arabian Peninsula?
It was the most extreme event in the UAE since record-keeping began in 1949. according to to the state-run Emirates News Agency. From April 15th to 16th, some parts of the country received more than their normal annual rainfall in a 24-hour period. Heavy rains in desert regions are not uncommon, but they are not unheard of – as the UAE sees it. heavy rain and flooding For example, 2016.
A drainage system in a coastal city in the United Arab Emirates (UAE) has been overwhelmed by spills, causing flooding. Dramatic images of a plane driving through stagnant water at Dubai International Airport have been widely shared online.
In neighboring Oman, died in flash flood At least 18 people. Parts of Bahrain, Qatar and Saudi Arabia also experienced unusual rainfall.
What is cloud seeding? Did it affect extreme rain?
Cloud seeding is a way to increase precipitation, From about the 1940s. This involves spraying powders such as silver iodide onto clouds from airplanes or rockets, or burning them from stations on the ground. Droplets of supercooled water form around these particles and fall to the ground as rain or snow.
Since 2002, the UAE has maintained one of the largest cloud seeding programs in the world. Planes regularly fly cloud-seeding missions in an effort to increase freshwater resources in arid regions.
Meteorologists at the UAE’s National Center of Meteorology (NCM) have further fueled speculation that cloud formations may be responsible for the recent rains. Saidbloomberg news That in the days before the storm, planes had spread clouds over the country. However, NCM later stated: statement That no seed was sown during the storm.
“We take the safety of our employees, pilots and aircraft very seriously,” the company said. “NCM does not conduct cloud seeding operations during extreme weather conditions.”
Even if cloud formation had occurred during the storm, it would have had at most a small effect on precipitation and would have been localized. The extent of rainfall across several countries and the generally limited influence of cloud species suggest that cloud occurrence almost certainly does not play a significant role. “There is no technology that can create or even significantly alter this type of rainfall event.” Maarten Ambaum at the University of Reading, UK statement.
He noted that cloud seeding would have little impact on clouds that were already predicted to bring rain to the region. And that assumes that cloud seeding is effective at all.
“Many claims of successful cloud seeding are false, scientifically flawed, or actually fraudulent,” he says. Andrew Dessler at Texas A&M University. “This makes most atmospheric scientists very skeptical about cloud formation.”
What weather factors were behind the rain?
The extreme precipitation was caused by large storms called mesoscale convective systems. Suzanne Gray Researchers at the University of Reading say this happens “when many individual thunderstorms coalesce to form a single large high-level cloud shield.”
Forecasters had predicted a high risk of flooding in the area for at least a week before the storm.Writing in progress XJeff Berardelli, a meteorologist at WFLA-TV in Florida, linked the storm to a blocking pattern created by a slow-moving jet stream.
Has climate change made rain worse?
Further analysis is needed to link this particular event to climate change, but climate change likely plays a role.
“These types of heavy rainfall events are likely to become more extreme with climate change, as a warming atmosphere retains more water vapor,” Ambaum said. Changes in temperature can also affect atmospheric circulation patterns in the form of changes in precipitation.
For example, recent study The same type of storm that caused this extreme rainfall has occurred in the region 95 times since 2000, with the most frequent occurrences on the Arabian Peninsula in March and April, researchers found. However, it has also been found that the duration of these storms has increased over the UAE since 2000, which may be linked to rising temperatures.
Alternative climate modeling study They predict that annual rainfall in the UAE will increase by 10 to 25 percent by mid-century, characterized by more intense precipitation events.
Twenty years ago, scientists announced the creation of a new miracle substance that would revolutionize our lives. They named it graphene.
Graphene is made up of a single layer of carbon atoms arranged in a hexagonal pattern, making it one of the strongest materials ever produced. It is more resistant to electricity than copper and has excellent heat conductivity.
The potential applications of graphene seemed limitless, with predictions of ultra-fast processors, quicker battery charging, and stronger concrete. It was even proposed as a solution for potholes in roads.

The scientists behind the discovery, Andre Geim and Konstantin Novoselov, received the Nobel Prize in Physics in 2010 for their work. The National Graphene Institute was established at the University of Manchester.
Despite the initial hype, the graphene revolution has not materialized as expected. Challenges in scaling up production have hindered its widespread adoption.
Sir Colin Humphreys, a materials science professor at Queen Mary University of London, pointed out that the main issue lies in the difficulty of producing graphene on a large scale.
He explained that the original method of creating graphene was not conducive to mass production and that significant investments by companies like IBM, Samsung, and Intel have been made to develop scalable production methods.
Recent advancements in manufacturing techniques show promise for the resurgence of graphene technology. Companies like Paragraph are now producing graphene-based devices in large quantities.
Graphene-based devices are being used for various applications, including sensors for detecting magnetic fields and differentiating between bacterial and viral infections.
Additionally, graphene devices are expected to be more energy-efficient than current technologies, offering a promising future for the material.
While the graphene revolution may have been delayed, it holds the potential to address pressing global challenges and significantly impact modern life.
Graphene “has the potential to make a real difference to modern life,” says Sir Colin Humphreys, professor of materials science.

From T-shirts with changing messages to carpets that can detect your position, the future of smart textiles seems to come straight out of a sci-fi novel.
Researchers now claim they have created a smart fiber that can achieve just that, without the need for a battery pack.
A team of Chinese researchers have developed textile-based electronics that utilize the human body as part of a circuit to harness electromagnetic energy from the environment.
This innovation could pave the way for a “body-bound” fiber electronics technology that functions without electronic chips or batteries and could be applied in various scenarios.
Co-author Chengyi Hou from Donghua University in Shanghai explained, “When electromagnetic energy passes through a fiber, it is converted into different forms of energy, including visible light or radio waves. Therefore, the fiber not only emits light but also produces an electrical signal when in contact with the human body.”
Hou highlighted that these radio signals are programmable by manipulating different aspects of the system, such as the fiber’s contact area with the body and its diameter.
The team stated that this method resolves a major challenge in integrating electronic systems into textiles, which is the necessity of rigid components.
Hou mentioned, “We have successfully achieved mass production of this new type of fiber electronics, which is as thin and soft as traditional fibers. The next step is to implement it.”
The team has created prototypes like a wearable cloth display with a cloth keyboard, intended for individuals with hearing impairments to aid in communication, as well as textile controllers for gaming.
Additionally, they developed a wireless tactile carpet that illuminates underfoot, providing emergency lighting at night and wirelessly transmitting signals to control household devices like lights.

An accompanying article suggests that this technology can also be utilized in robots, robotic prosthetics, and capturing haptic information to enhance human interactions and object recognition.
Dr. Luigi Occhipinti, a research director at the University of Cambridge specializing in smart electronics, biosystems, and AI, acknowledged the potential of this approach.
He stated, “By being constantly surrounded by various electromagnetic fields, we are developing innovative electronic textiles with skin sensors and unconventional electronics, powered uniquely through energy harvesting. This has the potential to unlock a new realm of self-powered wearable electronics for continuous health monitoring.”
Following a dry run of Taiwan’s presidential election this year, China is anticipated to disrupt elections in the United States, South Korea, and India with artificial intelligence-generated content, as warned by Microsoft.
The tech giant predicts that Chinese state-backed cyber groups will target high-profile elections in 2024, with North Korea also getting involved, according to a report released by the company’s threat intelligence team.
“As voters in India, South Korea, and the United States participate in elections, Chinese cyber and influence actors, along with North Korean cyber attack groups, are expected to influence these elections,” Microsoft mentioned.
Microsoft stated that China will create and distribute AI-generated content through social media to benefit positions in high-profile elections.
Although the immediate impact of AI-generated content seems low in swaying audiences, China is increasingly experimenting with enhancing memes, videos, and audio, potentially being effective in the future.
During Taiwan’s presidential election in January, China attempted an AI-powered disinformation campaign for the first time to influence a foreign election, Microsoft reported.
The Beijing-backed group Storm 1376, also known as Spamoflage or Dragonbridge, heavily influenced Taiwan’s elections with AI-generated content spreading false information about candidates.
Chinese groups are also engaged in influencing operations in the United States, with Chinese government-backed actors using social media to probe divisive issues among American voters.
In a blog post, Microsoft stated, “This may be to collect intelligence and obtain accurate information on key voting demographics ahead of the US presidential election.”
The report coincides with a White House board’s announcement of a Chinese cyber operator infiltrating US officials’ email accounts due to errors made by Microsoft, as well as accusations of Chinese-backed hackers conducting cyberattacks targeting various entities in the US and UK.
The UK Government has initiated a consultation to gather public and industry input on increasing the legal power of electric bike models from 250W to 500W in the UK. This move has sparked concerns in the fire protection community.
Electric bicycles utilize various types of batteries, with lithium-ion technology being the common choice. These batteries come in different shapes and sizes, such as cylindrical or box-shaped configurations.
Battery packs in electric bikes are composed of multiple cells connected in series and parallel to provide the necessary voltage and capacity. Incidents of fires linked to lithium-ion batteries are on the rise, posing risks to users of electric bikes and e-scooters.
Recent data disclosed in May 2023 by the Guardian newspaper revealed that defective electric bikes and e-scooters have caused injuries to 190 individuals and claimed eight lives in the UK. The London Fire Brigade noted a substantial increase in battery-related fires in 2023, with a rise of 78% compared to the previous year.
Potential causes of fires in lithium-ion batteries include mechanical or thermal shock, overcharging, and reactive materials interacting with each other, leading to heat generation and abnormal electrical behavior. Despite the benefits of higher wattage batteries in electric bikes, there are concerns about the increased risk of fires and other safety issues.
To mitigate the risk of battery fires, users are advised to avoid tampering with batteries, charge them within the recommended parameters, and store them in a safe environment away from flammable materials. Adherence to manufacturer guidelines and proper disposal of damaged batteries are crucial in preventing incidents of fires.

Poor and outdated technology is costing the United States enormous amounts of money.according to recent columns The Wall Street Journal said it would cost more than $1.5 trillion to fix, with “cybersecurity and operational failures, failed development projects, and maintenance of outdated systems costing $2.41 trillion annually.” There is.
According to the magazine, this “technical debt” lurks beneath the shiny newness of “an accumulation of band-aids and outdated systems not intended for today's use,” all of which need updating. It is said to be extremely sensitive.
And I don't know that.
I've been dealing with this problem every day for the past 20 years. My life revolves around outdated systems, outdated software, and patched databases. My company sells customer relationship management (CRM) software primarily to small and medium-sized businesses. And look at the old technology they still have.
It's not uncommon to come across older versions of Microsoft Office. One of his companies I know is still running Office 97. I see companies using QuickBooks on desktop computers. Remember ACT and GoldMine for contact managers? Yes, they're still there. Great Plains? MAS90? Yes, there are still remnants of these ancient accounting systems in today's products manufactured by Microsoft and Sage.
It's not uncommon to encounter companies with internal networks running legacy client/server applications on Windows machines.Approximately 81% of companies still writing paper checks to suppliers. My company's biggest competitor is not any other CRM software. Someone is walking away from a prehistoric, proprietary system built on top of his FileMaker Pro, which hasn't been updated since the system's creator passed away ten years ago.
Over the years, I have never faulted small business owners for not upgrading.
These people spent a lot of money implementing software systems back in the day. They'd have to come up with a pretty good reason to scrap it all and start fresh. Cloud? Better security? More integration? Maybe. But then again, wouldn't that money be better spent buying new equipment, repairing the warehouse roof, or medical care? And don't we hear about the mistakes made by ~? ? microsoft and Google And A.I. “hallucination” And that data breach Are the world's smartest people at the biggest technology companies that are supposed to work for them? Can we trust these companies and their shiny new applications? Why invite trouble?
Replacing or upgrading technology is one of the many decisions businesspeople have to make every year. They know the chaos it causes. And many of my clients shrug their shoulders and say it's not broken so why fix it?
Understood. But now my feelings are starting to change. No, I'm not siding with big tech companies. It's about inheritance.
More than half of small business owners in this country are over 50 years old, and the baby boomers currently running companies will likely aim to take the next step in the not-too-distant future. They expect to make the most money from the business they have built over the past few decades. But the same people who saved money on technology upgrades to invest elsewhere will be shocked. why?
Because this is a world of big data and unless the technology is up to date, the price of your business will be greatly affected. This is not a technical issue. It's a matter of evaluation. Buyers will quickly discount the purchase price to cover the cost of having to upgrade or replace these older systems.
My advice to business owners looking to leave their companies within the next 10 years is that it's time to upgrade. Otherwise, “technical debt” will cost you dearly.
It has been 100 days since the war in Gaza began, and it has become increasingly difficult to read the news. Her husband told me it might be time to talk to a therapist. Instead, on a cold winter morning, after fighting back tears as I read another tale of human tragedy, I turned to artificial intelligence.
“I’m pretty depressed about the state of the world,” I typed into ChatGPT. “It’s natural to feel overwhelmed,” the magazine responded, offering a list of practical advice, including limiting media exposure, focusing on the positive and practicing self-care.
I closed the chat. I was sure that I would benefit from doing all this, but at that moment I didn’t feel much better.
It may seem strange that an AI would even try to provide this kind of assistance. But millions of people have already turned to his ChatGPT, a professional therapy chatbot that provides convenient and inexpensive mental health support. Even doctors are said to be using AI to create more empathetic notes for patients.
Some experts say this is a boon. After all, AI may be able to express empathy more openly and tirelessly than humans, unhindered by shame or burnout. “We admire empathetic AI” by a group of psychological researchers I wrote recently.
But others are not so sure. Many people question the idea that AI can be empathetic and worry about the consequences if people seek emotional support from machines that can only pretend to care. Some even wonder if the rise of so-called empathic AI might change the way we think…
Exercising while wearing foundation changes the properties of your skin.

Wearing foundation while exercising can affect your skin health by changing the size of your pores and subsequently altering the release of sebum, which is responsible for keeping you healthy.
Lee Seok Ho The researchers at Texas A&M University in San Antonio recruited 43 college students, 20 men and 23 women. Participants first washed their faces with facial cleanser. The researchers then measured skin variables in different areas of the face, including pore size and sebum production.
A single layer of foundation was then applied to all participants’ faces, either on the forehead or cheeks, depending on the participant’s preference.
They then did a 20-minute moderate workout by running on a treadmill at 3 miles per hour (mph) for 5 minutes, 4 miles per hour for 10 minutes, and 5 miles per hour for 5 minutes.
After the training, the researchers repeated various skin measurements and found that areas with foundation had less sebum production than areas without makeup.
“This is a shining example of the negative effects of makeup during exercise,” the researchers wrote in their paper. “In this study, makeup use clogged pores and resulted in negative sebum scores.” The optimal amount of sebum is unknown, and too much can cause acne, while too little can cause skin irritation. To do.
Participants’ pore size also increased significantly in areas without foundation, but did not change significantly in areas with makeup. This suggests that this foundation may be inhibiting the natural enlargement of pores during exercise, preventing the release of sebum and sweat, which moisturize and cool the skin. The researchers did not assess whether these changes were related to skin problems.
Wearing foundation during exercise may not have a significant effect on most people who train for relatively short periods of time, but “we don’t know the effect on endurance-type athletes,” Lee said. say. The research team now wants to investigate the effects during longer exercise routines.
Shari Lipner Researchers at Weill Cornell Medicine in New York say the study’s split-face design is a good approach, but complicates comparisons because our skin characteristics vary across different parts of the face. Additionally, she says, the skin around the nose, mouth and eyes has a different thickness compared to the skin on the forehead and cheeks, so ideally these areas should have been studied as well.
CAPE CANAVERAL, Fla. — Researchers have identified a quasar with a black hole at its center that may be the most luminous object in the universe. This quasar is growing at an incredible rate, capable of consuming an amount equivalent to the sun in a single day.
The record-breaking quasar shines 500 trillion times brighter than the sun. Scientists reported in the journal Nature Astronomy that the black hole fueling this quasar is more than 17 billion times more massive than the sun.
Despite appearing as mere dots in images, scientists believe quasars to be formidable entities.
The disk of luminous gas and other material orbiting a quasar’s black hole is akin to a cosmic hurricane.
“This quasar is the most violent place in the universe as we know it,” said lead author Christian Wolff of the Australian National University.
The object, known as J0529-4351, was initially discovered by the European Southern Observatory in 1980 and misclassified as a star. It was not confirmed to be a quasar until last year, after telescope observations in Australia and the Atacama Desert in Chile.
“What’s interesting about this quasar is that it’s hiding in plain sight and was previously misclassified as a star,” said Priyamvada Natarajan of Yale University.
Further analysis revealed that the quasar consumes the equivalent of 370 suns a year, or one sun a day, and the black hole at its center has a mass between 17 billion and 19 billion times that of the sun. More observations are needed to understand its growth rate.
Quasars are located 12 billion light years away and have existed since the beginning of the universe. One light year is 5.8 trillion miles.
Today, not one, but five asteroids are hurtling past Earth, all at their closest approach.
The largest one was discovered just a few weeks ago. Potentially Dangerous 2024 BR4. Measuring between 140 and 300 meters in length, it is a sizable chunk of space rock. At its highest estimate, it would be about the size of an oil tanker, six Olympic-sized swimming pools, or as tall as New York City's Chrysler Building.
And just like the box of chocolates you might stuff your cheeks with, we have a few more surprises in store for you on the day. Dr. Darren Baskillan astronomer at the University of Sussex, said:
“On Wednesday, February 14, 2024, a total of five asteroids will pass Earth, all within 5 million kilometers.”
It may seem like a long way, but from an astronomical perspective, it's just a stone's throw away.
“The closest of these five is asteroid 2024 CU1, which is scheduled to pass about 52 percent further away than the Moon and is about 20 meters in diameter.”
In 2024, CU1 will be closest at 1:31 PM GMT (+/- 1 minute). However, it is only 20 meters in diameter, much smaller than the much talked about “city killer” called 2024 BR4.
How close will asteroid 2024 BR4 get?
Asteroid 2024 BR4, one of a group of asteroids that will fly past Earth today, will make its closest approach at a distance of 4.6 million km (2.86 million miles). In terms of AU, this is approximately 0.03 AU, well within the criteria for designation as a potentially hazardous object (see Meaning of a “Potentially Hazardous” Asteroid below).
(To convert kilometers per mile to AU, divide the distance in kilometers per mile by the distance in 1 AU of the same unit.)
Closest approach is expected to occur at 11:03 GMT today (±1 minute).
Will asteroid 2024 BR4 collide with Earth?
The Valentine's Day asteroid is hurtling through space at about 44,880 kilometers per hour (27,887 miles per hour), only slightly faster than the average speed recorded by Galileo during his six-year mission to Jupiter, but we… No need to worry. About influencing our heavenly oasis.
It passes us safely and poses no immediate threat to Earth.
“Asteroid 2024 BR4 will pass close to Earth 12 times further away than the Moon,” Baskill explains.
What do we know about Asteroid 2024 BR4?
Unfortunately, there are very few. In general, the larger the object, the brighter it is (the brighter the object, the lower the magnitude). NASA assigned asteroid 2024 BR4 a magnitude of 21.457.. It's not very bright.
However, we also need to know the object's albedo (surface reflectance), which is currently unknown. Current best estimates place the asteroid's size between 140 and 300 meters in diameter. But we know its trajectory with relative certainty. And today's visit will bring us the closest in 120 years to realizing BR4 in 2024.
Mysterious new weapon could threaten satellites in Earth orbit
Key Fame/Shutterstock
According to a series of reports, the US government has privately warned lawmakers and European allies that Russia is planning to launch a nuclear-capable space weapon.
The news comes after U.S. House Intelligence Committee Chairman Mike Turner announced: vague warning It cited a “grave national security threat” and asked US President Joe Biden to “declassify all information related to this threat” for more public discussion. Since then, news reports have revealed additional details about what Russia's mystery weapon is. Here's what we know so far:
Does this mean Russia aims to deploy nuclear missiles and bombs into space?
This point remains unclear.Report from ABC News and new york times The term “nuclear weapon” may mean a weapon capable of producing an explosion involving a fission or fusion reaction.If this is true, it would be a violation of the rules 1967 Outer Space TreatyIt prohibits signatories, including Russia and the United States, from placing nuclear weapons or other weapons of mass destruction in space.
Although a nuclear explosion in space would not directly harm people on Earth, it could destroy and disable multiple satellites.When the United States detonated a nuclear bomb in low Earth orbit during that period starfish prime In a 1962 experiment, the resulting radiation damaged or destroyed about a third of the satellites in low Earth orbit at the time.
However, there is another possibility that does not involve nuclear weapons.
What else does Russia have in its nuclear capabilities in space?
Russian space weapons may simply use nuclear power to power onboard systems. PBS News Hour U.S. officials said the Russian weapon was “probably nuclear-powered.”
Russia and the United States have used various forms of nuclear power in space for decades. One form includes nuclear fission reactors, such as those found in civilian nuclear power plants, which derive their power from an ongoing nuclear chain reaction.
The United States launched an experimental nuclear reactor into space in 1965, while Russia reportedly launched at least 34 nuclear reactors aboard satellites between 1967 and 1988. World Nuclear Association.
The United States, Russia, and other countries have also launched space missions using radioisotope systems. These use heat from the natural decay of radioactive materials as a power source, but they provide much less power than nuclear fission reactors.
What does this Russian space weapon actually do?
News reports agree that Russian weapons are designed to target satellites in space, rather than directly harming anyone or anything on the ground. However, if this weapon is able to knock satellites out of orbit, these objects could fall to the planet's surface and cause severe damage. If they blow away, the resulting cloud of space junk could threaten other satellites and even the International Space Station. This could even trigger a Kessler syndrome scenario, where a chain reaction of space debris gets out of control and makes it virtually impossible for satellites to survive in Earth orbit.
Various countries, including Russia, the United States, China, and India, have previously tested anti-satellite weapons (ASATs), which shoot missiles from Earth and shoot down objects in orbit. But countries have been much quieter about whether they have actually deployed ASAT weapons into space.
What does Russia say about the potential of this weapon?
A spokesperson for Russian President Vladimir Putin's government reportedly called the U.S. warning a “malicious hoax” aimed at pushing the U.S. Congress to pass legislation authorizing more military aid to Ukraine. Ta. Reuters. Since Russia launched a full-scale invasion of Ukraine in February 2022, the United States and Europe have supported Ukraine's military resistance against Russian forces.
Why does Russia need new anti-satellite weapons?
Satellites are important for both military and civilian applications that have a huge impact on modern life. They monitor the weather, power GPS systems, provide space-based surveillance, and enable communications. For example, SpaceX's Starlink satellite constellation has proven essential to the Ukrainian military in coordinating drone and artillery fire against Russian forces on the battlefield.
A U.S. official quoted by PBS NewsHour suggested that Russian space weapons have “electronic warfare capabilities to target U.S. satellites critical to U.S. military and civilian communications.”
According to some sources, Russia has spent years developing a space-based electronic warfare system that can jam communications signals to and from satellites. report This is by the Secure World Foundation, a space security organization based in Colorado.Victoria Samson at the Secure World Foundation Said Such a Russian space weapon could be powered by nuclear power.
So how dangerous is this new anti-satellite weapon?
The good news is that if this space weapon sabotages satellites rather than physically destroying them, it will not cause a catastrophic space debris scenario like Kessler syndrome. However, it can still be dangerous.
Space weapons that use electronic warfare to jam signals could effectively disable satellites. That could disrupt critical battlefield communications, render GPS guidance systems inoperable and obscure reconnaissance satellites, making it more difficult for the United States to coordinate military forces around the world.
The Guardian confirmed that Meta is considering expanding and “reconsidering” its hate speech policy regarding the term “Zionist.” On Friday, the company contacted and met with more than a dozen Arab, Islamic, and pro-Palestinian groups to discuss plans to review its policies to ensure that “Zionist” is not used as a substitute for Jewish or Israeli. An email seen by the Guardian revealed this information.
According to an email sent by Meta representatives to invited groups, the current policy allows the use of “Zionist” in political discussions as long as it does not refer to Jewish people in an inhumane or violent manner. The term will be removed if it is used explicitly on behalf of or on behalf of Israelis. The company is considering this review in response to recent posts reported by users and “stakeholders,” as reported by The Intercept.
Another organization received an email from a Meta representative stating that the company’s current policy does not allow users to attack others based on protected characteristics and that a current understanding of language people use to refer to others is necessary. The email also mentioned that “Zionist” often refers to the ideology of an unprotected individual but can also refer to Jews and Israelis. The organizations participating in the discussions expressed concerns about the changes leading to further censorship of pro-Palestinian voices.
In addition, Meta gave examples of posts that would be removed, including a post calling Zionists rats. The company has been criticized for unfairly censoring Palestinian-related content, which raises concerns about the enforcement of these policies.
In response to a request for comment, Meta spokesperson Corey Chambliss shared a previous statement regarding the “increasing polarized public debate.” He added that Meta is considering whether and how it can expand its nuanced response to such language and will continue to consult with stakeholders to improve the policy. Policy discussions take place during high-stakes periods of conflict, and accurate information and its dissemination can have far-reaching effects.
More than 25,000 Palestinians have been killed since the attack on Gaza began in October 2023. Implementing a policy like this in the midst of a genocide is extremely problematic, and it may cause harm to the community, as stated by an official from the American Arab Anti-Discrimination Committee.
Minecraft is a game for humans, but it can also be useful for AI
Mine Craft
Mine Craft Not only is it the best-selling video game of all time, it could be the key to creating adaptive artificial intelligence models that can handle a variety of tasks just like humans.
stephen james and colleagues at the University of the Witwatersrand in South Africa developed a benchmark test in which. Mine Craft Measure the general intelligence of your AI model. MinePlanner evaluates AI's ability to ignore unimportant details when solving complex problems in multiple steps.
According to James, much AI training is “cheating” by giving the model all the data it needs to learn how to do a job, and nothing irrelevant. While this is a useful approach if you're writing software to perform a specific task, such as predicting the weather or folding proteins, it's not useful if you're trying to create artificial general intelligence (AGI).
James says that future AI models will need to tackle wicked problems, and he hopes MinePlanner will guide that research. The AI working to solve in-game problems recognizes scenery, extraneous objects, and other details that are not necessarily needed to solve the problem and should be ignored. You need to investigate your surroundings and decide for yourself what is necessary and what is not.
MinePlanner consists of 15 construction problems, each with easy, medium, and hard settings, for a total of 45 tasks. The AI may need to perform intermediate steps to complete each task. For example, building a series of stairs to place blocks at a certain height. This requires AI to narrow down the problem and plan ahead to achieve the goal.
Experiments with state-of-the-art planning AI models ENHSP and Fast Downward, open-source programs designed to process sequential operations in pursuit of an overall goal, show that both models successfully complete difficult problems. I couldn't do it. Fast Downward was only able to complete one medium problem and five easy problems, while ENHSP completed all but one easy problem and all but two medium problems. By completing all of the above tasks, they achieved slightly better results.
“You can't step in and tell a human designer exactly what to care about and what not to care about for every task that an AI needs to solve,” James said. say. “That's the problem we're trying to address.”
Lenses featuring a trippy spiral design could be an alternative to traditional multifocal lenses. It seems to produce clearer images than standard multifocal lenses, even in dimly lit areas.
The lens was created by the inventor Laurent Galinier.when bertrand simon He met Galinier through a scientific collaboration at the Institute of Optics Graduate School in France, and he immediately wanted to test lenses in the lab.
They are round lenses like traditional contact lenses, but the surface is carefully turned into a spiral using a lathe. This spiral shape changes the path that light rays take through the lens. That is, the lens does not have a single focal point, but several focal points, some closer to the lens and some farther from it.
It's unclear exactly how the spiral shape does this, but Simon said it appears to twist the light rays and create vortexes of light (like small tornadoes of light) that somehow influence each other. ing.
In the lab, Simon and his colleagues analyzed laser light passed through a spiral lens and simulated the process on a computer. In direct comparison with traditional multifocal lenses, the spiral lenses provided more clarity and detail when more light passed through them, and performed better in dim light conditions.
Therefore, spiral lenses may be suitable under various lighting conditions. For example, it could be useful for people who use multifocal lenses while driving at night, Simon said. He tried the spiral contact lenses himself and said that while the hard material was uncomfortable in contact with his eyes, it saved him the hassle of removing his glasses to look at his cell phone. With the spiral lens, I could see the screen clearly.
james wolfthorn According to researchers at Aston University in the UK, many people experience problems focusing on nearby objects, even if their distance vision is corrected. Innovations like spiral lenses are promising, but only clinical trials can prove how much of a difference new technology will actually make for people, he says.
Simon says it's possible to create a more compact camera by replacing part of the lens with a spiral lens version, but the team will first investigate the science behind spiral light. We would like to do further testing.
Deep underground in the heart of Asia, two giant plates are colliding with each other. Violent, slow-motion collisions between the geological plates are continuously shaping the towering Himalayas. However, newly discovered research suggests that this ongoing tectonic collision is also dividing Tibet in half.
A group of Chinese and American scientists conducted a study of underground seismic waves from earthquakes in and around Tibet and analyzed the geochemical composition of gases in surface hot springs. They found evidence that the Indian plate may be behaving unexpectedly as it collides with the Eurasian plate.
This research, which has not yet undergone peer review, was presented at the American Geophysical Union’s annual meeting in December. The scientists theorize that as the Indian plate continues its thrust beneath the Eurasian plate, it may be splitting apart beneath Tibet, separating the eastern and western halves of the slab. This fissure could have significant implications for the stability of the region, increasing the risk of earthquakes and other hazards.
The findings of the study provide an interesting and plausible explanation for the dynamic activity in this region, according to Barbara Romanowitz, a professor at the University of California, Berkeley. She also suggests that this potential split in the Indian plate may create a zone of weakness that could lead to large earthquakes.
The study proposes that the lithospheric mantle, one of the hard parts of the Earth’s crust, are sloughing off, leaving the crust behind, causing controversy within the scientific community as to how the collision of the Indian and Eurasian plates would occur or what it would mean for the Earth.
The region where this collision is occurring is unique and serves as a natural laboratory for scientists to understand the process of continental collision in real time. It is compared to a game of hide-and-seek, providing a brief snapshot of a particular process of continental collision.
Microscopic marine fungi are abundant, with approximately 2000 species discovered to date.
Dayarathne MC et al. (2020)
Take a walk along the coast almost anywhere in the world and you'll see colorful patches of life growing on rocks, seawalls, and driftwood. These are lichens, a mutualistic partnership between fungi and algae. In the UK, this may include brightly colored orange marine lichens and yellowish coastal sunburst lichens, as well as many other Drabber species.
Lichens are typically thought of as terrestrial organisms, and in fact, the majority grow inland on rocks, tree trunks, leaves, and soil. However, coastal organisms are not creatures that accidentally washed ashore from land; they are marine-adapted species found only on or in close proximity to shores. Until recently, they were considered to be outliers in the almost entirely terrestrial fungal kingdom. No more. “Fungi are present in every marine ecosystem we observe,” says Michael Cunliffe of the University of Plymouth in the UK.
Research on marine fungi is currently rapidly increasing, but their exact role and importance in marine ecosystems remains a mystery. Nevertheless, there are high hopes that it could save us from the two great scourges of the 21st century: antibiotic resistance and plastic pollution.
What are marine fungi?
The existence of marine fungi has been known for many years. The earliest descriptions were published in his mid-19th century to his early 20th century, but these were largely ignored by mainstream mycologists. Most of the species discovered are found on the roots of seaweed that live near the coast.

Researching the use of artificial intelligence (AI) in the world of work, Hilke Shellman
She thought it would be a good idea to try some tools. Among them was a system called a one-way video interview system aimed at supporting recruitment. my interview.
She got a login from her company and started her experiment. She first chooses the questions she asks as a hiring manager, then video records her answers as a candidate, and then her proprietary software records the words she used and the intonation of her voice. was analyzed. She scores how suitable she is for the job.
She was delighted to have an 83% match rate for the role. But when she redid her interview in German, which is her native language, instead of English, she received an error message and instead she received the appropriate score (73%). I was surprised that it did. And she wasn’t even trying to answer the question this time. But read the Wikipedia entry. The record the tool made up of her German was gibberish.When her company showed her their tools Already knew
Since she didn’t speak English, she was graded mainly on intonation, but we used a robot voice generator to read her English answers. Here again she recorded her high score (79%) and Shellman gave her a headache.
“If simple tests show that these tools may not work, then we need to seriously consider whether we should be using them in recruiting,” said Shellman, an assistant professor of journalism at New York University and an investigative reporter. “There is,” he says.
The experiment, which was conducted in 2021, is described in Schellman’s new book, algorithm.
Explore how AI and complex algorithms are increasingly being used to help hire and then monitor and evaluate employees, including firing and promoting them. Mr. Shellman previously guardian
In addition to experimenting with the tools, we also talk about this topic with experts who have researched the tools and experts who are on the receiving end of the tools.
This tool is attractive to employers because it aims to reduce the time and cost of filtering through large numbers of job applications and increase workplace efficiency. But Shellman concludes that they do more harm than good. Many hiring tools are not only based on troubling pseudoscience (for example, the idea that your voice intonation can predict your success on the job doesn’t hold true, Shellman says), but they also have the potential to discriminate. There is also.
The ‘fountain of youth’ isn’t locked away in a philosopher’s stone or a mythical body of water, according to new research. In fact, US scientists say the key to slowing aging is hidden within our bodies.
It was announced in new research that: The secret to anti-aging lies in white blood cells known as T cells. The researchers behind the study discovered that these cells can be reprogrammed into senescent cell-killing machines known as CAR (chimeric antigen receptor) T cells.
When they tested this treatment on mice, they lost weight, improved their metabolism and glucose tolerance, increased physical activity, and led healthier lives. Moreover, there is no tissue damage or toxicity.
“If you give this to old mice, it rejuvenates them. If you give this to young mice, it slows down the aging process. There are currently no other treatments that can do this.” Corina Amor Vegas is an assistant professor at Cold Spring Harbor Laboratory (CSHL) in the United States and one of the authors of the paper.
Researchers call this treatment a “living drug.” That’s because when CAR T cells are genetically modified, they become more aggressive in attacking a group of cells known as senescent cells.
Senescent cells are responsible for many of the conditions and diseases that develop as we age, such as obesity and diabetes. As the years go by, we accumulate more and more of them, and this causes a buildup of harmful inflammation. However, CAR T cells may be able to eliminate them and slow the effects of aging.
This treatment is already approved in the United States to treat blood cancers. But this is the first time scientists have shown that CAR T cells can slow or even reduce the effects of aging.
There are already drugs that can eliminate senescent cells, but these must be taken repeatedly. The effects of CAR T cells, on the other hand, are long-lasting. If he takes one dose when he is young, he will be protected for life.
“With CAR T cells, you could potentially get away with just one treatment. For chronic diseases, this is a big advantage. Think about the patients who need treatment,” said Amor Vegas. If administered intravenously, it will be fine for several years. ”
Scientists will then investigate whether the cells not only make you healthier for the rest of your life, but also help you live longer.
Artist's impression of a pulsar orbiting a black hole – one possible interpretation of the mysterious binary star system
Daniel Hutseller (artsource.nl)
Some 40,000 light-years away, a strange object could be either the heaviest neutron star or the lightest black hole ever seen, and it resides in a mysterious celestial void that astronomers have never directly observed. .
Neutron stars form when a star runs out of fuel and collapses due to gravity, creating a shock wave called a supernova and leaving behind an extremely dense core. Astrophysical calculations show that these nuclei must remain below a certain mass, about 2.2 times the mass of the Sun, or they will collapse further to form a black hole.
However, black holes have only been observed to have a mass more than five times that of the sun, leaving a gap in scale between neutron stars and black holes. Gravitational-wave observatories have observed several dense objects in this gap, but astronomers have never discovered them with conventional telescopes.
now, Ewan Barr Researchers at Germany's Max Planck Institute for Radio Astronomy discovered an object with 2.5 times the mass of the Sun by observing pulsars orbiting around it. A pulsar is a neutron star that emits pulses of light at regular millisecond intervals due to a strong magnetic field.
As predicted by Albert Einstein's theory of relativity, pulsars emit light with great regularity, but very large nearby objects can distort these rhythms. Dr. Barr and his team were able to calculate the mass of the pulsar's partner by observing the pulsar's pulses for more than a year using his MeerKAT radio telescope in South Africa.
“What we've discovered in this binary system appears to go beyond that [upper limit for neutron star mass]This suggests that there is some new physics going on here and that this is either a new type of star, or simply a black hole, the lightest stellar-mass black hole yet discovered. “There will be,” Barr said.
Pulsars are located in globular clusters, which are dense regions of stars and some rare objects that can pass close to each other. These unusual interactions could explain the mysterious object, Barr said.
If it's a black hole, researchers will be able to test theories of gravity that weren't possible before. “A pulsar is just a ridiculously accurate measuring device in orbit around a black hole, but it's not going anywhere. It's going to be around for the next billion years,” Barr says. “So this is an incredibly stable and natural test bed for investigating the physics of black holes.”
“If it's a neutron star, it would be more massive than any neutron star we've ever seen,” he says. Christine Dunn At Durham University, UK. “This actually tells us about the ultimate density that a star can support before it collapses under its own gravity and becomes a black hole. We need to understand the physics of matter at such extreme densities. I don't know what the limits are.”
Barr and his team plan to observe the pulsar with other telescopes over the next few years, looking for clues about what the object is. If it were a black hole, we would see the pulsar's orbit change over time, as the black hole dragged through spacetime around it, much like a ship dragging a small boat behind it. Or if it's a neutron star, more sensitive instruments might be able to detect the light.
WWhen the weather is nice, Buxton Boarding School moves lunch outside. Students, faculty, staff, and guests grab food from the kitchen and eat together under a white tent overlooking the Berkshire Mountains of western Massachusetts.
As the end of the school year approached last June, conversation turned to final assignments (English class was finishing Moby Dick) and year-end fun (a trip to the local lake was planned). Ta. It was, in most ways, a typical teenage afternoon. However, no one was using a cell phone.
Buxton was completing the first year of a simple but novel experiment: banning cell phone use on campus. Or rather, a smartphone.
Instead, the school will require everyone on campus, including staff, to light phone, that is, a “dumb” phone with limited functionality. The device can make calls and send texts (slowly), but it cannot load modern applications. Instead, it comes with intentionally cumbersome versions of the Music and Maps apps. They are about the size of a deck of playing cards and have black and white screens.
One student said: “It's like the devil's baby of the iPad and Kindle.”
But most people agree that schools are better off with these infernal devices. (Yes, that includes students.) There are fewer interruptions during classes, more meaningful interactions on campus, and less time spent on screens.
“We've found a pretty good way to deal with this problem,” said Scott Hunter, who teaches English and music, about smartphones. Buxton senior Bea Sass added: “I think people are a lot more social.”
FFor many teachers, students' cell phone use is frustrating. “That's every class, every time period,” said Mark McLaughlin, a math teacher at Near Car Knee High School in Oregon. “The worst part of my job is being the cellphone police.”
Educators across the country report fighting a near-constant battle with their phones.school districts in virginia The survey found that about a third of teachers asked students to put away their phones five to 10 times during class, and 14.7% did so more than 20 times during class. .
When I was in junior high school in Canada investigated According to staff, 75% of respondents believe that mobile phones have a negative impact on students' physical and mental health. Nearly two-thirds believed the device was also having a negative impact on their academic performance.
“This is a big problem,” said Arnold Glass, a psychology professor at Rutgers University. Researched the impact of mobile phones on student grades. “If they are allowed to look at their cell phones during class, they will drop half to the entire grade.”
Ian Tomonblak, a career guidance counselor at Lamoille Union High School in northern Vermont, is also faced with the proliferation of cell phones at his school. “There are kids who get Snapchats or text messages during the day and it just ruins their whole day,” he says. Another problem he sees is students using their cell phones to coordinate trips to collective restrooms in order to hang out during class. “I feel like it distracts me from learning on an academic level.”
Lunch time at Buxton School.
When I told Tromblak about Buxton's experiment, he was intrigued. He noted that one of the things this would address is the argument from students that they need a phone to contact their parents. And teenagers often adapt to new parameters relatively quickly, he said. He remembers learning at the last minute on a field trip with his students that not everyone was allowed to use cell phones. At first, the news was apocalyptic.
“They were very upset. They didn't know how to handle themselves. It was really tense,” Tromblak said, recalling the drama. However, during the trip, the kids almost forgot about their cell phones, and at one point they took it upon themselves to police a girl who secretly tried to call the source of the rope.
“At the end of the first day, we were sitting around the campfire and they were saying, 'I haven't thought about my phone all day,'” Tomblak said. “It was really cool.”
TTo some extent, Buxton experienced a similar progression through stages of panic, grief, and ultimately some acceptance. “When it was announced, I was almost sick,” then-senior Max Weeks said. And while he's still not happy about the switch to Litephone, saying it was a “unilateral” decision, he said overall it was “not as bad as I expected.”
It's an open secret that students still sneak cell phones into their rooms on campus, and some are testing the limits more than others. “People get pretty temperamental and get caught,” said Yamaira Marks, also a senior at Buxton. But smartphones are generally difficult to find on campus.
That includes staff. The school's principal, Peter Beck, said he ditched his iPhone for a Litephone and installed his old GPS system in his car for when he needed to go out into the world. He is thrilled with how his first year went.
Because Buxton uses a narrative evaluation system, it is difficult to determine how the new phone policy is impacting academic performance. But culturally, Beck says, the movement has often led to changes in small but cumulatively meaningful ways.
“People are crazy about the lounge. They stay after class and chat,” says Beck, who estimates they are now having more conversations than ever before at school. “The frequency of all these face-to-face interactions is orders of magnitude higher.”
IDuring the blissful summer that Hemesh Chadarabada spent with his grandmother in 2018, they watched endless movies and ate her grandmother's chicken biryani. Late one evening, while Chadaravada, then 12, was sitting alone in front of the television, Jayasree got up in her nightgown and went to her home in Guntur, southern India, to make her a cup of tea. Ta.
After returning to her bedroom, Chadarabada went into the kitchen and noticed that her grandmother, then 63, had left the gas on.
“She was recently diagnosed with Alzheimer's disease, and I was still in shock. What would have happened if I hadn't been there?” Chadaravada says.

Chadaravada knows that Jayasree is not only a loving grandmother but also a dynamic and successful woman with a high-profile career as a civil servant who interacted with Telangana's top politicians and policy makers. Ta.
But Alzheimer's disease changed her forever. “She would wake up at 3 or 4 in the morning and she would go outside thinking she was on the train,” he says.
During that happy summer, Chadarabada, a self-confessed geek from Hyderabad who loves robotics, decided he wanted to invent a device to help people like his grandmother.
Now 17 years old, Chadarabada is ready to start building a device to detect falls and wandering in Alzheimer's patients, something that is not possible with currently available devices.
Light and compact, Alpha Monitor can be worn as a badge or armband and sounds an alarm when the wearer begins to move, alerting caregivers if the patient falls or wanders.
Most similar devices work over Wi-Fi or Bluetooth, so if a person moves outside of the frequency's restricted range, they lose connectivity and, with it, monitoring. However, Alpha Monitor Lolait uses.
Chadarabada taught himself by watching YouTube videos about robotics and electronics and developed 20 prototypes.

Rishi Sunak needs to decide whether to support Britain’s creative industries or bet everything on the artificial intelligence boom, Getty Images’ chief executive has said.
Craig Peters, who has led Image Library since 2019, made the comments amid growing anger in the creative and media sectors over the material being collected as “training data” for AI companies. His company is suing a number of AI image generators for copyright infringement in the UK and US.
“If you look at the UK, probably about 10% of GDP is made up of creative industries like film, music and television. I think it’s dangerous to make that trade-off. It’s a bit of a complicated trade-off to bet on AI, which is less than a quarter of the country’s GDP, much less than the creative industries.”
In 2023, the government, in response to consultation from the Intellectual Property Office, set a goal to “overcome the barriers currently faced by AI companies and users” when using copyrighted material, and promised to “support access to copyrighted works.” input to the model.”
This was already a step back from previous proposals for broad copyright exceptions for text and data mining. In a response to a House of Commons committee on Thursday, Viscount Camrose, a hereditary peer and under-secretary of state for artificial intelligence and intellectual property, said: This will help secure the UK’s place as a world leader in AI, while supporting the UK’s thriving creative sector.”
The role of copyrighted material in AI training is under increasing pressure. In the US, the New York Times sued OpenAI and Microsoft, the creators of ChatGPT, for using news articles as part of training data for their AI system. OpenAI said in a court filing that it is impossible to build an AI system without using copyrighted material.
Peters disagrees. Getty Images collaborated with Nvidia to create its own image generation AI that is trained using only licensed images.
The tide is changing within the industry as well. A dataset of pirated e-books, called Books3, is hosted by an AI group whose copyright takedown policy at one point even includes a costumed person pretending to masturbate with an imaginary penis while singing. Similar to the lawsuit by Getty and the New York Times, a number of other legal actions are underway against AI companies over potential training data breaches.
Ultimately, whether courts or even governments decide how to regulate the use of copyrighted material to train AI systems may not be the final word on this issue. Peters is optimistic that this result is not a foregone conclusion.
aAs you may have noticed, we’re in the midst of a craze about something called generative AI. Many hitherto ordinary people, and economists alike, are riding a wave of irrational enthusiasm about the potential for change. It’s the newest new thing.
Two antidotes are recommended for people suffering from fever. The first one, Hype Cycle Monitor created by consultant Gartner
This indicates that the technology is currently at the “peak of inflated expectations” before plummeting into the “trough of disillusionment”. the other one is, hofstadter’s law
describes the difficulty of estimating the time required for difficult tasks: “Even when Hofstadter’s law is taken into account, it always takes longer than expected.” Just because a powerful industry and its media patrons are losing their marbles about something doesn’t mean it’s going to wash over society as a whole like a tsunami. Reality moves at a much slower pace.
of )This article aims to explain “What tractors and horses can tell us about generative AI.” The lesson is that tractors have a long history, but they took a long time to transform agriculture. He has three reasons for this. Early versions were not as useful as backers thought. Introducing these required changes in the labor market. And farms had to reinvent themselves to use them.
So history suggests that whatever transformations AI hypemongers predict, they will materialize more slowly than expected.
However, there is one exception to this rule. It’s computer programming, or the business of creating software. Ever since digital computers were invented, humans have had to tell machines what they want them to do. Because machines could not speak English, machine code and programming languages such as Fortran, Algol, Pascal, C, C++, Haskell, and Python evolved over generations. So if you wanted to communicate with a machine, you had to learn to speak Fortran. , C++ or whatever, is a tedious process for many people. And as the title the great Donald Knuth gave to the first book of his seminal five-volume guide suggests, programming has become something of an esoteric craft. the art of computer programming . As the world went digital, this craft became industrialized and rebranded as “software engineering” to downplay its artisanal origins. But mastering it remained an esoteric and valuable skill.
Then along came ChatGPT and the amazing discovery that not only could you create apparently clear sentences, but you could also create software. What’s even more remarkable is that when you outline a task with a plain English prompt, the machine writes the Python code needed to accomplish that task. Often the code is not perfect, but can be debugged by further interaction with the machine. And suddenly, a whole new perspective opened up. Even non-programmers can tell a computer to do something without having to learn computer conversation.
inside new yorker Programmer James Summers recently wrote the following: Lamentation essay What are the implications of this development? “A range of knowledge and skills that previously took a lifetime to acquire are being swallowed up all at once,” he said. “For me, coding has always felt like an endlessly deep and rich field. Now, I want to write a memorial to it. I’ve been thinking about Lee Sedol. Sedol is the world One of the best Go players and a national hero in South Korea, he is now best known for losing to a computer program called AlphaGo in 2016.”
That seems a little strange to me. The evidence we have suggests that programmers are embracing AI assistance like ducks to water.a recent research
For example, 70% of software developers are using or plan to use AI tools in their work this year, and 77% of them have a “favorable or very favorable” opinion of these tools. I found out that They see them as a way to increase your productivity as a programmer, speed up your learning, and even “improve accuracy” when writing computer code.
This doesn’t seem like defeatism to me, but the attitude of experts who see this technology as “power steering for the mind,” as the saying goes. In any case, they don’t sound like horses. economist's story. But just as tractors ultimately transformed agriculture, this technology will ultimately transform the way software is developed. In that case, software engineers will need to be more like engineers than craftsmen. It’s almost time (says this engineer and columnist).
When you open a new website, do you choose to either accept or reject all cookies? New research suggests that choosing to reject cookies may actually reveal more information about yourself than if you simply “accept all cookies.”
In this digital age, cookies, which are pieces of data, are stored on our devices for various purposes such as remembering login information. However, cookies can also be used to track online behavior and tailor ads to individuals. This has led many people to refuse cookies in order to keep their personal information private and to prevent companies from using their data for marketing purposes.
Surprisingly, recent research presented at NeurIPS 2023 has shown that certain demographics are more likely to reject cookies, which could have implications for advertisers. Contrary to popular belief, rejecting cookies does not necessarily mean hiding one’s identity.
Results from the study showed that acceptance of cookies varies depending on the country and age of the individual. For example, individuals in the US over the age of 34 were more likely to refuse cookies, inadvertently sharing more of their data.
Advertisers could access five pieces of information from a person who accepts cookies, but only two pieces from a person who rejects them. In other words, declining cookies may not necessarily protect your identity. This demographic, which includes older adults, has been found to have less trust in tech companies and is more likely to reject cookies as a result.
It is important to note that the privacy laws in the United States are not as stringent as those in the EU, meaning that user data may not be as protected, especially for individuals who reject cookies.
Privacy is important to some people, but not to everyone
Researchers have found that older Americans are less likely to accept cookies, with only 28% of them choosing to do so. This compares to 40% of younger Americans who typically accept cookies. This indicates that the decision to reject cookies has a greater impact for younger Americans in protecting their identity.
The authors of the research are hopeful that their findings will help shape regulations for new technologies such as AI and inform policymakers. They emphasize that the decision to accept or reject cookies is not as simple as it may seem and may not always produce the intended effect.
So… does it make sense to refuse cookies?
Ultimately, the impact of privacy decisions is more complex than users may realize, and there are no definitive answers. Some recommendations include using more privacy-friendly browsers and supporting stronger privacy laws and regulations.

In the relatively short period of space exploration history, the moon has experienced significant changes as a result of human activity. From the historical significance of our first footprints to the damage caused by spacecraft crashes, our impact on the moon is evident and nearly preserved within the moon’s regolith.
For the past 1.1 billion years, the Moon has been in the Copernican Era, the current epoch. Now, there are calls for a new lunar era to be formally defined: the lunar Anthropocene. This proposed era started in 1959 with Russia’s first-ever landing of the Luna 2 spacecraft on the moon. With upcoming missions like NASA’s Artemis and Lunar Gateway, further changes are expected.
Dr. Justin Holcomb, a space archaeologist, and researcher at the University of Kansas, USA, was interviewed.
What markers suggest that a new era has begun on the Moon?
Unlike the Earth’s Anthropocene, the moon provides a unique setting for human activity to be recorded due to its limited systems and ability to preserve the entirety of human history. The relatively slow impact of meteorite collisions has historically been the primary cause of change on the Moon, contrasting with the addition of the human variable now present on the lunar surface.
What’s the biggest impact we’ve had there?
When humans land on the Moon, they significantly impact the surface. However, accidental impacts, such as spacecraft crashes, pose a significant risk and have occurred multiple times since 2019. These accidents jeopardize planned areas of operation and can potentially erase important historical sites on the Moon.
What else do we have left there?
Various artifacts and items have been left on the Moon, including personal items, scientific equipment, and the national emblem on India’s rover. It’s argued that the space debris on the Moon should be considered as space heritage rather than just waste, and thus, it needs to be protected as such.
How are human activities changing the Moon’s geological processes, and to what extent can humans disrupt the balance of the Moon’s system?
The impact of human activities on the Moon’s geological processes, such as the movement of lunar regolith and potential contamination of ice due to rocket fuel, presents concerns for the future. These impacts could have far-reaching consequences and affect the balance of the Moon’s system.
How will the Moon change further for future space missions after 2024?
With a focus on mining and the potential for private companies to be involved in future space missions, the Moon is expected to experience significant changes in the coming years. The increase in planned lunar missions indicates a new phase in the relationship between humans and the moon. With the rise of private space companies, the landscape of space exploration has shifted.

In the late 1990s, when I was studying for my PhD, I read an article touting the “next big thing” in the food sector. To be honest, the next highlight didn’t seem very appetizing. Apparently, within the next 10 years, we’ll all be eating Beetleburgers.
Entomophagy, the eating of insects, is common in many parts of the world. Considering the ethical issues of livestock farming, the article boldly proclaimed that insect farms are the future of food.
Insects raised without welfare issues are excellent at converting foodstuffs that are unavailable to us into proteins that we can use. Additionally, they require far less space than livestock and produce far fewer greenhouse gas emissions than cows.
But despite some obvious benefits, a quarter of a century later, customers in developed countries still aren’t eating flies or baking with beetles. The reason is obvious. More than 1,000 species of insects are eaten around the world, most commonly in the tropics, but Western societies generally do not eat “bugs.”
Like the bushtucker trial I’m a Celebrity Get Me Out of Here Eating insects is a repulsive idea to many people.

Articles extolling the virtues of eating insects continue to appear frequently in the media. And while the headlines often feature shock values, authors are increasingly focusing on the ethical and climate-friendly aspects of insect farming.
If you look beyond the headline ‘Grasshoppers for Beginners’, you’ll quickly see that insects are already well-positioned to play a more important role in our food chain. Instead of eating fried grasshoppers with a side salad of mealworms, we’re developing better ways than ever to use insects as food for our favorite animals.
Insects could be a protein-rich game changer
The star of this insect animal feed revolution is the black soldier fly (Hermesia Illuscens). Adults are only about 16 mm (about 0.5 inches) long and resemble small, independent wasps. But soldier flies don’t have stingers and don’t sting, so this mimicry is just an evolutionary ploy.
A widely distributed species, the key to the black soldier fly’s importance is its larvae. This is because black soldier fly larvae are “non-selective” feeders. This is a polite way of saying that you will eat almost anything.

They thrive on all kinds of food, from manure to animal and vegetable food waste. This property makes it excellent for waste disposal. For this alone, the flight of black soldiers is beneficial to us, but only before we turn them into animal feed.
The waste treatment process is called “ento remediation” and uses large chambers called bioconverters that house large numbers of black soldier fly larvae. These larvae consume food and other organic waste, producing soil-like organic residue that can be used as a rich fertilizer.
Inside the bioconverter, the larvae grow rapidly, and more than 50 percent of the weight they gain is protein. Once they reach the pupal stage (the stage of metamorphosis into an adult), they reach their nutritional peak. At this point, it has already helped convert the waste into fertilizer, which can be harvested and used as animal feed.

Insect animal feed can replace traditional animal feed, which often relies on soybean meal. Soybeans have a high environmental cost due to the land and water required to grow them and the resources required for transportation.
Although much of the research on animal feed production has focused on feeding livestock such as pigs and chickens, the black soldier fly is also attracting attention as a food source for farmed fish. Currently, the majority of feed for farmed fish often consists of fishmeal. Fishmeal is also used as livestock feed and is made by drying and crushing fish.
While this makes good use of fish parts we don’t eat and bycatch that can’t be returned to the ocean, fishmeal production can promote overfishing and the decline of fragile marine ecosystems.
Replacing fishmeal with sustainably farmed insects could revolutionize this important aspect of marine conservation.

From pet food to human food
However, black fruit flies are not the only species raised as animal feed. Some species of locusts breed very well and are relatively easy to maintain.
Insects are small and do not require much space, so it is possible to keep them under strictly controlled conditions to optimize their growth and reproduction. Those who keep reptiles are probably familiar with house crickets (Aketa Domestic). These light brown crickets are widely grown as pet food, but their potential as a source of protein for livestock is also attracting attention.
These insects may also eventually become a more direct part of our diet. The Italian Cricket Farm in Turin, Italy, is investigating the possibility of processing crickets into a protein-rich “insect flour” that can be incorporated into our food products. Currently awaiting European food safety approval, it is precisely this type of processing that could become a culturally acceptable way for insects to enter our diets.
In fact, crickets are quite delicious even when eaten without being processed into flour. A few years ago I ran an insect-eating workshop at the Cheltenham Science Festival. At that time, a local chef prepared a series of dishes for people to try. Beer-battered fried brown crickets sandwiched between sage leaves were a snack that people tried at first out of curiosity, but were so delicious they returned within seconds.

Cricket farms in Italy produce around 200,000 crickets a year, which can be scaled up relatively easily. The production efficiency of crickets is amazing. Every 1 kg (2.2 lb) of crickets requires only 1.7 kg (3.7 lb) of feed to produce. Compare this to the 10 kg (22 lb) of feed required to produce 1 kg of beef and the benefits are clear.
Additionally, the final product is incredibly nutritious, containing twice the protein of beef, as well as a variety of vitamins, minerals, fatty acids, and other nutrients.
Changing tastes and ethics
As with any new idea in food production, potential disadvantages must be carefully considered.
It is clear that what an animal eats can influence the quality of the meat that is subsequently produced. Research on this is ongoing, but data so far suggests that while insect diets can affect the fatty acid content of meat, these changes have no negative impact in terms of taste and are not noticeable. It has been shown that this is not the case.
Another important issue to ponder is the ethics of raising insects. Ethical concerns about animal use are complex and change in response to changes in society and our scientific understanding.
Over the past few decades, we have seen much higher welfare standards introduced into livestock farming than were thought necessary in the past, but many would argue that there is still a long way to go.
These welfare advances have focused primarily on mammals, secondarily on poultry, and to a lesser extent on fish. However, insects are not mentioned at all in ethical discussions about animal use.

In fact, we tend to think that insects cannot feel pain or suffering. However, this view is beginning to change.
We are beginning to learn more about the internal world of insects, and are discovering that they may be able to feel what we perceive as pain. Although this is an emerging field of research, the conclusion is that we may need to rethink the way we think about insects in many cases.
Having said that, I think it is actually very unlikely that we will change our views until insects are given the same welfare measures as “traditional” farm animals. The biggest advantage of using insects for food, either directly or through animal feed, is that they are environmentally friendly.
Dredging oceans for fishmeal and growing soybeans for protein feed are environmentally harmful, associated with high carbon costs and habitat loss or degradation.
On the other hand, raising insects has the potential to significantly reduce environmental impact. They occupy less space, use fewer resources to produce more protein, can utilize waste produced by humans, and do not rely on habitat development or displacement.
Crane fly cakes and locust bread may not be on your plate anytime soon, but insect-raised pork, chicken and beef certainly will be. Maybe that article from 25 years ago was onto something after all. Insects may really be the future of food.
Apple expressed concerns about potential “irreparable harm” after the White House backed a ban on imports of certain watches due to a dispute over blood oxygen technology.
The tech giant has submitted an emergency motion to the court, seeking permission to continue selling two popular models, the Series 9 and Ultra 2, until the patent dispute with medical monitoring tech company Masimo is resolved.
Apple has requested the ban to be temporarily lifted until U.S. Customs determines whether a redesigned version of its watch infringes Masimo’s patents, with a decision expected on January 12th.
Masimo has accused Apple of stealing pulse oximetry technology for monitoring blood oxygen levels and incorporating it into their watch, as well as luring some of its employees to switch to Apple.
The US ITC has ordered a ban on the import and sale of models utilizing blood oxygen level reading technology.
Wealth management analyst Dan Ives stated that the halt in watch sales before the holiday season could cost Apple $300-400 million, but the company is still expected to make nearly $120 billion in sales for the quarter, including the holiday period.

U.S. Trade Representative Katherine Tai upheld the ITC’s decision, but previously purchased Apple Watches with blood oxygen measurement capabilities are not affected by the ban.
Apple contests the ITC’s decision, claiming it is based on factual errors and that Masimo does not sell significant quantities of competing products in the U.S., and would not be harmed by a ban on orders.
Immune system researchers have designed a computational tool to improve pandemic preparedness. Scientists can use this new algorithm to compare data from very different experiments and more accurately predict how individuals will respond to disease.
“While we are trying to understand how individuals fight off different viruses, the advantage of our method is that it can be applied to other organisms, such as comparing different drugs or different cancer cell lines. It has general applicability in academic settings,” says Dr. Tal Einab. D., La Jolla Institute of Immunology (LJI) assistant professor and co-leader of the new study.
This study addresses a major challenge in medical research. Labs that study infectious diseases collect very different types of data, even those that focus on the same virus. “Each dataset becomes its own independent island,” he says Einav.
Working closely with Dr. Rong Ma, a postdoctoral fellow at Stanford University, Einav set out to develop an algorithm to help compare large datasets. His inspiration comes from a background in physics, where scientists can be confident that their data falls within the known laws of physics, no matter how innovative the experiment. E is always equal to mc2.
For example, researchers may be able to design better vaccines by understanding exactly how human antibodies target viral proteins.
The new method is also thorough enough to give scientists confidence behind their predictions. In statistics, a “confidence interval” is a way to quantify how certain a scientist’s predictions are.
“When people from different backgrounds come together, there is great synergy,” says Einab. “With the right team, we can finally solve these big unsolved problems.”
Activision Blizzard executives are considering a possible countersuit against California regulators who claimed the gaming giant had a toxic “frat boy” workplace, but only dropped the lawsuit last week, On The Money reported.
The California Department of Civil Rights, which had been investigating the developer of “Call of Duty” and “Candy Crush” since 2021, dropped the explosive allegations on Friday.
“Neither the courts nor independent investigations have established systematic or widespread sexual harassment,” authorities acknowledged in court documents last week.
California’s stunning admissions say there is no evidence that “senior executives ignored, condoned, or condoned a culture of systemic harassment, retaliation, or discrimination,” and that neither Activision’s board of directors nor CEO Bobby Kotick responded to complaints of misconduct. He also admitted that he had not handled the matter inappropriately.
Nevertheless, Activision ended up paying a $54 million settlement to resolve the lawsuit ($47 million of which was earmarked for pay disparity claims).

This has angered some Activision executives, who are drafting defamation lawsuits against the company.
The agency’s former director, Janet Whipper, was fired by Gavin Newson a year after she sued Activision, accusing Tesla of “racial discrimination,” a claim that was also unsubstantiated, according to court documents. It turned out that there was no such thing.
Other Activision insiders want to simply put this chapter on the back burner, concerned that an appeal would be tantamount to returning to the belly of the beast, insiders said.
Accusations that women were “subjected to constant sexual harassment, including groping” and that management fostered a “sexist culture” were enough to wipe the company’s market capitalization by $20 billion in a few months. Ta.

The tablet contains a vibration motor powered by a small silver oxide battery. When stomach acid reaches the intestines, the outer layer of stomach acid dissolves. This closes the electronic circuit and begins to vibrate.
Shriya Srinivasan, Giovanni Traverso, MIT News
A vibrating drug that tricks the brain into thinking it’s full could one day treat obesity. This approach is significantly less invasive than gastric bypass surgery, and may be cheaper and have fewer side effects than drugs such as Wegovy and Ozempic.
Giovanni Traverso Researchers at the Massachusetts Institute of Technology have developed a pill that is about the same size as a standard multivitamin. The tablet contains a vibrating motor powered by a small silver oxide battery that is safe to swallow. When the tablet reaches your intestines, stomach acid dissolves the outer layer of the tablet. This closes the electronic circuit and begins to vibrate.
In experiments with pigs, some of the animals were given the tablets 20 minutes before being fed. These pigs ate about 40 percent less than pigs that were not given the tablets. They also had higher levels of hormones in their blood that typically signal a feeling of fullness.
Researchers believe the pill has potential as a treatment for obesity and hope to test it in humans “soon,” Traverso said. “This is a huge health problem, affecting more than 40 percent of the U.S. population, for example.”
He says the pill’s vibrations activate the same receptors that sense when the stomach lining expands after a large meal, sending a signal to the brain that you’re full. The prototype version vibrates for 30 minutes until the battery dies and passes on its own.
Traverso said future versions could be adapted to stay in the stomach semi-permanently and be turned on and off wirelessly as needed. She said people will likely react differently to the device, but it typically turns on automatically for short periods of time each day to reduce appetite, or is controlled by a smartphone app to suppress hunger pangs. It is also possible to do so.
Previous research by the same group found that Electrical stimulation of the stomach lining can actually cause hunger pangs, may lead to the treatment of anorexia in cancer patients. “I think this is really exciting because we’re just learning what we can do by stimulating different parts of the gastrointestinal tract in different ways.” [gastrointestinal] Traverso says. “When we eat, we feel full, but the question is can we induce that feeling of fullness? Can we create that illusion?
Toyota will recall 1.12 million vehicles worldwide due to a defect affecting airbags.
The recall applies to 2020-2022 model year vehicles, including Avalon, Camry, Corolla, RAV4, Lexus ES250, ES300H, ES350, RX350 Highlander, and Sienna Hybrid, that do not have a functional Occupant Classification System (OCS) sensor. It may disappear.
A short circuit in the sensor on these models could prevent the airbag from deploying as designed.
Sensors ensure that the airbag does not deploy if a small adult or child is seated in the front seat.
Toyota Lexus, a brand owned by Toyota Motor Corporation, will inspect the OCS sensor and replace it if necessary, free of charge to owners.
The Japanese auto giant plans to notify customers by mid-February 2024 if their cars are subject to a recall.
Toyota announced a recall of 3,500 RAV4 models in the United States in July 2022 due to interference between internal parts that could cause OCS sensors to falsely detect occupants.
According to the National Highway Traffic Safety Administration, airbags in the front of vehicles have saved more than 50,000 lives in the United States over 30 years.

Older airbags have evolved over the years to deploy the same for all drivers and occupants.
This could cause injuries and, in rare cases, death to children, small adults and unbelted passengers who get too close to the airbags when they deploy, authorities said.
Researchers from Indiana University and the University of Notre Dame focused on reversing vascular remodeling through an epigenetic pathway involving the protein SPHK2, as reported in the journal Circulation Research. A potential treatment has been discovered. This innovative approach could transform the treatment of this serious lung disease.
Researchers at Indiana University School of Medicine’s South Bend Regional Campus and colleagues at the University of Notre Dame have discovered a new therapeutic target to treat pulmonary hypertension. This form of hypertension particularly affects blood vessels in the lungs. The team’s research and findings were recently published in the journal circulation research.
Pulmonary hypertension is a complex and often fatal condition in which the heart works harder than normal to pump blood to the lungs. The exact cause of pulmonary hypertension is unknown, but one of its hallmarks is thickening of pulmonary blood vessels caused by cell overgrowth, also known as vascular remodeling.
Discovery of new treatments
Margaret A. Schwartz, M.D., professor of pediatrics at IU School of Medicine and senior author of the study, said there are few treatments for pulmonary hypertension, and they usually treat the symptoms of vascular remodeling rather than the remodeling itself. Ta.
Dr. Schwartz said that an interesting finding of her team was the discovery of an epigenetic pathway through the protein SPHK2 that can reduce and potentially reverse vascular remodeling in pulmonary hypertension.

“This is one of the first reversible mechanisms of pulmonary hypertension identified,” she says. “Patients with pulmonary hypertension are usually given drugs to lower blood vessel pressure in the lungs or to help the heart contract to pump blood, both of which are symptoms of vascular remodeling. Our research focuses on targeting an epigenetic reversal of this mechanism. Ultimately, stopping the vascular remodeling process entirely may be the answer.”
Schwartz said the concept is similar to cancer treatment.
“In the case of cancer, we don’t just treat the symptoms, we stop the tumor from growing,” she says. “Vascular remodeling is a different mechanism, but the idea is that treatments target the mechanism rather than the symptoms.”
Main findings and future directions
Other key findings from the study include:
SPHK2 promotes the development of pulmonary hypertension through hyperacetylation of histone H3K9 and contributes to vascular remodeling in pulmonary artery smooth muscle cells (PASMCs).
SPHK2 deficiency results in decreased pulmonary vascular resistance, right ventricular hypertension, and thickened distal vessel walls.
EMAP (endothelial monocyte activation polypeptide) II plays an important role in stimulating the nuclear SPHK2/S1P epigenetic regulatory axis, suggesting cooperation between SPHK2 and S1P.
EMAPII may be a major driving force of epigenetic-mediated vascular PASMC reprogramming and remodeling in pulmonary hypertension.
Pulmonary endothelial cells are priming factors for the EMAPII/SPHK2/S1P axis that alters PASMC-specific acetylome through histone H3K9 hyperacetylation.
Schwartz and the study’s lead author, Dr. Dushani Ranasinghe, who was a member of Schwartz’s lab when Schwartz was a graduate student at Notre Dame, also thanked Dr. Schwartz for this episode. were interviewed about their findings. Podcast “Discover CircRes”It is produced by. circulation research.

A recent study of more than 300 chronic spontaneous attack urticaria (CSU) patients found that acupuncture may provide limited symptom relief, but the clinical significance remains unclear. . An accompanying editorial highlights the potential of acupuncture in the treatment of non-painful conditions and the need for widespread clinical openness to its use.
A randomized controlled study of more than 300 participants diagnosed with chronic spontaneous urticaria (CSU), or hives, suggests that acupuncture may provide some symptom relief. However, the clinical significance of these results remains unclear. This study was recently published in the journal Annals of Internal Medicine.
CSU is the most common form of chronic urticaria and is characterized by recurrent itching, skin lesions, or swelling that lasts for more than 6 weeks in the absence of a specific provoking factor. More than 90 percent of CSU patients require urgent treatment to relieve itching. Therefore, itch management is one of the main goals in the treatment of CSU.
Effect of acupuncture on CSU
Researchers at Chengdu University of Traditional Chinese Medicine randomly assigned 330 people diagnosed with CSU to either 4 weeks of acupuncture, 4 weeks of sham acupuncture, or a waiting list (control), and 4 weeks after treatment. Patients were followed for weeks to see if the acupuncture treatment improved. It leads to the improvement of CSU symptoms. Symptom changes were measured using the Weekly Urticaria Activity Score (UAS7).
Patients in the acupuncture group reported improved UAS7 compared to sham acupuncture and waitlist management. However, the clinical significance of the observed reduction in itch severity scores is unclear, as the difference between intervention and control did not meet the minimum clinical difference (MCID) threshold. The incidence of adverse events was highest in the acupuncture group, but the adverse events were mild and transient.
Editorial insights and broader implications
An accompanying editorial by Mike Cummings of the British Medical Acupuncture Society highlights that these trial results are interesting because they illustrate the effectiveness of acupuncture in conditions not characterized by pain.
Although the clinical significance of this finding was not clear, the authors believe that clinicians may use acupuncture as an adjunct to influence outcomes, even in more severe disease states. This suggests that you should always keep this in mind. The editorial suggests that acupuncture is often ignored as a treatment because it lacks commercial support compared to other modern interventions.

European Union regulators are expected to impose a ban on the App Store rules affecting some music streaming services and potentially levy heavy fines on Apple, according to a report by Bloomberg News published on Wednesday.
Based on the report, EU authorities are in the process of finalizing a decision that would prevent Apple from blocking music services that redirect users from the App Store to alternative subscription options, citing sources familiar with the investigation.

The decision is expected to be announced early next year, with potential fines for Apple amounting to up to 10% of its annual revenue, as reported by Bloomberg.
The investigation was triggered by a complaint from Sweden’s Spotify Technology four years ago, claiming that it was compelled to raise monthly subscription prices due to costs related to Apple’s App Store rules.
Earlier this year, the European Commission filed a complaint against Apple, deeming the conditions to be unnecessary and potentially resulting in increased costs for customers.

Apple’s stock saw a slight increase in afternoon trading.
