View of the lunar surface taken from the tilted position of the SLIM lander
JAXA
Most landers we send to the Moon will operate for one lunar day, or about two weeks on Earth, until they die from the extreme cold of the lunar night. But Japan’s Smart Lunar Lander (SLIM) has now survived two nights on the moon and continues to send images back to Earth, an amazing feat.
SLIM is Japan’s first lunar lander and becomes the fifth country to land a spacecraft on the lunar surface. When the plane landed on January 19, it was tilted and the solar panels could not provide enough power to continue operating for more than a few hours. After nine days, the sun began to move again, moving across the sky.
But just three Earth days later, the lunar night began. Nighttime temperatures on the moon can drop as low as -133°C (-208°F), potentially damaging the spacecraft’s batteries and electronics. Normally, the lunar lander shuts down on a lunar night and never wakes up again, but it started up again on February 25 as the sun rose above Slim.
This in itself was a surprise. The lander was not specifically designed to withstand lunar nights, and its original mission was scheduled to end at night. So, as night approached again, this seemed to be the end of SLIM.
However, on March 27th, the SLIM official account I posted an image above X has the following caption: “Last night, we received a response from SLIM confirming that SLIM achieved its second success during the night. Last night, the sun was still high and the equipment was hot, so I quickly turned on my navigation camera. It looks like the lander will be able to resume analyzing its surroundings within the next few days.
Its survival is especially surprising because while some spacecraft use radioactive elements to stay warm, SLIM does not. “This is a significant achievement considering we are not using radioisotope heaters,” he says. Haim Benaroya at Rutgers University in New Jersey. “This result is important and impressive, given that this is a major design consideration for electronics (and people) to survive moonlit nights.” SLIM has failed while many other spacecraft have failed. Analyzing how they survived may help us understand how they stay warm on the moon.
There’s new evidence that it pays to yell at referees at sports stadiums. The evidence comes in a study by Joel Guerret, Caroline Blais, and Daniel Fisset of the University of Quebec in Outaouais, Canada, titled “Verbal attacks on Major League Baseball umpires influence decision-making.” They published it in a magazine psychological science.
Guerret, Brace, and Fisset examined 10 years of Major League Baseball game data. They stress that these games are played out in an “ecological environment rife with hypercritique.”
They discovered what they called “the double-sided benefits of resorting to verbal abuse.” After being heavily criticized, “home plate umpires were less likely to call a strike to the complaining team’s batter and more likely to call a strike to the opposing team’s batter.”
Mr. B. McGraw (who did not specify his name) brought the matter to Feedback’s attention, impressed by the authors’ development of a disciplined academic voice: “Our findings support the hypothesis that under certain conditions, verbal aggression can be advantageous to the accuser.”
ice cream nozzle
Questions arise when the nozzle starts to collect foreign matter, but if you diligently clean the nozzle after using it to dispense a scoop of ice cream, the question becomes less pressing. Because if you don’t clean the nozzles and other parts of your food machine, things can grow healthy (from a material point of view).
Psychrotrophic bacteria are bacteria that can grow at low temperatures, temperatures such as those that can occur in refrigerators and freezers.
Research called ”Psychrotrophic bacteria with virulence and colonization properties live in the ice cream production environment”, the need for nozzle maintenance comes to mind. The purpose of this discussion is to prevent horror stories from happening. The authors, from Italy’s University of Naples Federico II, said: “We provide evidence for the existence of a complex microbial community that overcomes the sanitary conditions of ice cream production facilities.” Therefore, Harken is an ice creamer. Please clean the nozzle.
your chocolate nozzle
For example, considering what shape nozzle to use for 3D printing chocolate can raise unexpected and vaguely related questions.research in frontiers of psychology We focus on one surprisingly subtle and complex question. So when it comes to the question of taste, how much chocolate is too much chocolate?This study is called ”Effect of bouba and kiki-like shapes on the perceived taste of chocolate pieces”.
”Booba” and ”kiki” are coined words, and psychological experiments suggest that they somehow evoke the concept of shape. To many people, a ”bouba” looks curvy and a ”kiki” looks pointy. The researchers found evidence that Booba was subtly sweeter than Kiki, but to measure the difference they had to limit the amount of chocolate in each bite.
They wrote: “Previous studies have found no difference in participants’ reports of a difference in taste after actually eating round and square chocolate pieces. Because there was so much chocolate in the cup, we thought that the actual taste might have dominated the effect of perceived shape on taste.”
They devised a solution. “We designed a ring-shaped stimulus with no chocolate filling in the center to avoid the need to ingest excess chocolate taste or flavor while maintaining perceived shape differences.”
Reducing chocolate consumption by using sweeter-tasting forms, they say, would reduce chocolate production and, in turn, reduce greenhouse gas emissions, benefiting even those who don’t eat chocolate. The Booba/Kiki-inspired choice of chocolate dispenser nozzle is implicit and may be more than just a symbolic weapon in the fight against global warming.
diagonal nozzle
If you really want to install a turbofan engine in a jet aircraft, and if you want quietness, make the nozzle diagonally. Make a chamfer. These are the words of Julien Christophe, Julien de Dekker and Christophe Schramm of the Von Karman Institute for Fluid Dynamics in Belgium.Writing in progress flow, turbulence, combustionThey explain the reason as follows: “The beveled nozzle provides noise reduction at all emission angles, with up to 2 dB reduction at the receiver’s position perpendicular to the plate.” For peace of mind, bevel.
cryptographic emoji
If there’s a contest for a jargon-heavy study about a sketchy financial business, perhaps you could submit your cryptocurrency to a study called ”Emoji-led crypto market reaction”, written by Xiaorui Zuo, Yao-Tsung Chen, and Wolfgang Karl Härdle.
The word “pith” is sometimes defined as “the spongy white tissue that lines the inside of the peel of oranges and other citrus fruits.” This study contains a pointed explanation of itself. “We leverage GPT-4 and his fine-tuned Transformer-based BERT model to perform multimodal sentiment analysis and focus on the impact of emoji sentiment on the crypto market.” The paper does not say what “BERT” is. “Similar sentiment analysis techniques could be applied to a broader range of financial markets,” the paper says.

○On March 14, Team 0% was on the verge of finishing their seven-year mission to conquer all 80,000 incomplete levels of the 2015 Nintendo game Super Mario Maker. They only had two challenging maps, “Herb Trimming” and “The Last Dance,” left to conquer. But as time ticked away, Nintendo dropped the bombshell that they would be shutting down the game’s servers on April 8th. Any level unfinished by then would remain that way forever. Unfortunately, Team 0% fell short at the final hurdle.
When Super Mario Maker was released for the Wii U, players discovered the thrill of creating their own levels and sharing them online. However, to upload a level, players had to beat it themselves first. Little did they know that one of the remaining levels was a hoax.
From its launch, Super Mario Maker inspired players to create incredibly difficult levels with inventive designs. A website called Super Mario Maker Bookmarks tracked every uploaded level, generating stats on completion rates. In 2017, a Reddit user named the0dark0one compiled a list of levels yet to be beaten, unknowingly sparking a journey.
Jeffie, the founder of Team 0%, launched a Discord server in December 2017 to tackle the backlog. They faced technical challenges due to the volume of data but persisted, clearing the initial list after eight months. However, new levels kept pouring in, each more challenging than the last.

The team developed training levels within Super Mario Maker to teach newcomers the unique skills required to ace tricky levels. As they sharpened their skills, the task became more daunting with the deadline looming, requiring nearly 100 levels to be completed daily.
As the team neared the finish line, they faced suspicions regarding the legitimacy of the last level, “Trimming the Herbs.” Some speculated it might have been completed using cheats like TAS (Tool-Assisted Speedrun). Ultimately, the creator admitted to using TAS, tarnishing the victory moment.
Despite the disappointment, players continue to tackle “Trimming the Herbs” before the shutdown. The accomplishment lies not just in completing every level in Super Mario Maker, but in preserving the efforts of all creators in the game’s history.

Louder Than riot Hip-hop has existed for the past 50 years as an important means of social and political expression, alongside a reputation for excess and controversy. Louder Than a Riot explores how this vibrant artistry born in some of America’s most neglected communities is being policed, coinciding with the rise of mass incarceration and… is examining in detail whether they have expressed prejudice within their own ranks. Hosts Rodney Carmichael and Sidney Madden combine fascinating reporting and interviews to explore how rappers have often run afoul of the criminal justice system, before dissecting misogyny and homophobia within hip-hop. I’ll explore.
blog era Brothers Jeff and Eric Rosenthal host this fascinating series that dissects a niche but pivotal year in hip-hop history. After the birth of the Internet, but before the streaming era took off, blogs could make or break a rap artist, and the frenzied writing of blogs began to influence the very type of music that was made. Some people do. In “The Blog Era,” the Rosenthal brothers cover the music he made between 2007 and 2012 (after which SoundCloud became a dominant force), featuring appearances from J. Cole to Kid Cudi. It features people and depicts the fate of the editor who ran the site. .

In my family, we have developed a habit of ordering affordable DVDs whenever we discover a show or movie that we know we want to watch again (which is a trick in itself!).
Towards the end of 2020, when I relocated to a new apartment in another area of Seattle, I ended up disposing of a trash bag full of VHS tapes. While it was inevitable due to spatial constraints, I had a strong feeling that I might regret it. A sudden shift in the TV landscape where channels started charging viewers for access to old content (from Jaws to Airplanes to classic dramas) literally overnight caught us off guard. We hadn’t anticipated such a rapid change. mountain aspect
‘In the end, it will become a future landfill site.‘
I enjoy the concept of having a DVD collection and perusing its shelves like a rental store.
However, I can’t shake off the realization that most of the valuable possessions we accumulate will eventually end up in future landfills, left for future generations to grapple with. I am also keenly aware that at some point, I will either have to take on the responsibility of disposing of and redistributing my various interests, or pass the task on to a close relative. In that sense, the thought of owning even a modest DVD collection extensive enough to cover all bases fills me with dread. I think of my grandparents and the boxes they amassed over their lifetimes, destined for disposal in the dump, their parents’ attic, or the charity shop. TypeON negative
‘There’s a significant disparity in quality…‘
I may be considered a Luddite, but I’m not particularly captivated by this trend of streaming.
I recently watched a movie on Disney+. Newer movies often exhibit overly dark visuals (a complaint echoed by several acquaintances). Older films are frequently displayed in incorrect proportions or feature subpar soundtracks. My son has recently subscribed to Prime Video mainly for the TV shows but has yet to explore the movie offerings. For some reason, I harbor doubts about being able to find the movie I wish to watch.
Fortunately, we still have a local HMV store. Nothing beats the experience of strolling there, browsing around for an hour or so, and selecting a Blu-ray. The disparity in quality between watching movies via streaming and physical media is quite pronounced. “After Hours”, “Eraserhead”, “Boogie Nights”, “Naked”, “The Conversation”, “The Passengers”… While casual movie enthusiasts may indulge in a Netflix binge, more dedicated film fans prefer a shelf stocked with physical media. man without fear

‘This current phase is the worst‘
Rental spaces will once again thrive, though it may take time, bringing a sense of nostalgia for some and a fresh experience for others. As mentioned in the article, there is a resurgence fueled by the revival of vinyl records. The more enthusiasts of the original content and the younger generation realize that they can’t access the authentic material, the more the market will adapt. However, this phase is undoubtedly the most challenging, especially with streaming services pulling titles in multiple directions. Mr username 2014
‘the hype is real‘
I recently canceled my streaming subscription and started collecting “final format” 4K Blu-rays.
The hype is justified. The quality is exceptional, with no discernible drop in visual and audio quality that can happen with streaming. Some discs are particularly well-optimized for the format. Oppenheimer is a prime example (using high-quality headphones and viewing on a 4K disc makes for a very satisfying 3-hour experience). The advent of Villeneuve is also commendable.
As a gamer, I rarely have time to dedicate to playing for more than 20 hours nowadays, so having a PS5 gives me something to engage with. blue jay 2011
‘Household finances are stretched‘
Speaking personally, I believe the streaming industry will eventually rue its efforts to lock in customers. Unfortunately, household budgets are tight, and the cost of subscribing to streaming services adds up. And it’s not just me – there are numerous services vying for attention, leading to decision fatigue.
When movies and similar content are sold on DVD or Blu-ray, the consumer is committing to a one-time purchase. As a result, these companies, and the film industry as a whole, may end up forfeiting a significant portion of their downstream revenue while also being under pressure to ensure customer satisfaction. As this discussion underscores, many of us still yearn for the ability to purchase movies in physical formats. buzz 2023
‘I have reverted‘
Honestly, I shifted to streaming platforms for movies and music for a while, but I found myself reverting back. Not only did the platform remove content I desired (movies and shows), but (especially when it came to music) changing platforms essentially meant I was “purchasing” music when I wasn’t truly owning it. I decided to change my approach. I lost money and didn’t actually possess my music. Because I had never truly bought the music in the first place, my wallet disagreed with the arrangement. That realization made me uneasy about the entire situation. Additionally, DVDs turn out to be much more cost-effective to own. Beacon of Hope Discount
‘very cluttered‘
It’s quite cluttered. I keep the CDs in a disc folder and discard the cases. While some may consider it sacrilege, it’s a satisfying compromise for me. Seven Highter
‘I’m not fixated on the format‘
Having films in digital format is too convenient for me to go back to physical formats. I do, however, continue to buy DVDs and Blu-rays of movies that aren’t digitized, but it’s a hassle to remove the DVD from its case, go to the DVD player, and start it up. …With digital media, you can initiate a movie in moments, regardless of your location. I’m not hooked on any particular format or medium. The main desire is to be able to watch our favorite movies whenever and wherever we want, and digital media is the best option for that. bf_Silver Town
‘I wasn’t intrigued until DVDs were introduced‘
Collecting movies was never as popular as amassing books or music (CDs, records, tapes). I had no inclination toward it until DVDs made their debut.
What I miss about the rise of physical media is the ability to visit someone’s home, peruse their collection of books, records, and DVDs, and discover their diverse interests. It’s a conversation starter. Jifujiji

‘Biggest film loss since the fires in the old studio vaults‘
We are witnessing the greatest loss of films since the fires that ravaged the old studio vaults. While some may argue that inaccessible films still exist somewhere, what if no one is able to view them?
Furthermore, digital formats are subject to frequent changes. Eventually, all digital copies of films will become obsolete. Will Disney or any other entity go to the lengths and expense of transferring all their popular movies to a new format? Possibly.
But will they undertake the arduous and costly task of migrating thousands of potentially forgotten films that haven’t seen the light of day in years and are buried in long-unused databases? Highly unlikely. son of the desert
‘I no longer live like an obsessive hoarder‘
Two years ago, I donated thousands of DVDs and Blu-rays to charity shops. I’ve abandoned the life of an obsessive hoarder and now find more peace of mind. With numerous old and new titles to watch, there are discs in my possession that I’ve never viewed in decades, some of which I’ve even given away while still in their original shrink wrap. Had streaming been available 30 years ago, it might have paid off my mortgage. R Gouveia
‘Film production courses‘
One of the reasons I’ve bought and continue to purchase numerous DVDs over the years is for the bonus content such as director commentaries, behind-the-scenes features, and interviews with cast and crew. While David Fincher’s “Seven” may be available on some random streaming service, the DVD’s commentary track alone is a treasure trove for film enthusiasts. sagarmatha 1953
‘DVDs are delicate and not everlasting‘
I still retain all my DVDs and am actively acquiring new ones. Many movies are not consistently available on streaming services, if at all, hence retaining them as physical media is crucial. The only challenge is that DVDs are susceptible to damage and cannot stand the test of time. The same can be said for DVD players. I’ve contemplated buying a new DVD player as a backup. While I do utilize a streaming service, it often has limited offerings and I struggle to find what I’m looking for, particularly when it comes to “older” movies from the 1920s, 1930s, and 1970s. Recently, I revisited the original “Ladykillers” – the remakes just don’t compare. about
‘It’s not an either-or situation‘
For me, it’s not about choosing one over the other. Streaming (via the usual platforms) has its place. It allows for discovering new movies or trying something different. Physical media, on the other hand, enables me to build my collection of movies that I can’t stream or that I prefer to own while watching them again. iron moog 007
My daughter used my credit card to book a 5-month stay using Airbnb after taking an internship in Toronto. After the host accepted the booking, she received an email saying the entire stay had increased by £4,000 for her (plus 39% for her).
In a panic, she canceled because she couldn’t afford to pay the extra fee. Airbnb took it. There is a £1,962 handling fee plus £682 cleaning fee and tax. Her daughter canceled immediately, so it is unlikely that your reservation will be lost.
Airbnb endlessly cites its terms of service. I asked the host to give me the money back, but he said he wouldn’t give it back. Feels as if it helped this guy perpetuate something. Seems like a scam.
JS, on mail
I’m surprised Airbnb didn’t resolve this issue in your favor before I got involved. You were asked to pay an additional 39% after booking – seriously? Fortunately, the company has now refunded you the full amount.
I was told that I should have declined the host’s request for additional fees. In that case, it was up to the host to decide whether to proceed at the original rate or cancel.
You wonder who at the company came up with the terms and conditions that allow for such a request, but all’s well that ends well. I hope your daughter enjoys Toronto.

Many of us include staple foods like pasta and rice in our diets for balance, while avoiding unhealthy options like potato chips and sugary snacks. However, determining the healthiness of processed and packaged foods based on their labels can be challenging.
It’s essential to understand that all foods can have a place in a healthy diet, but not all are equally nutritious. Rather than relying solely on food labels, it’s crucial to consider how these foods fit into your overall lifestyle and goals, taking into account factors like health, finances, work, and time constraints.
When faced with headlines about certain foods increasing the risk of disease by a certain percentage, it’s important to remember that these numbers represent relative risks in the population, not individual risks. Factors like the amount and frequency of consumption, overall diet, and disease likelihood all play a role in determining actual risk.
Nutrition is not isolated but influenced by evidence, hype, and context when making healthy choices. Here are some common supermarket products that are often misunderstood:
“Premium” Instant Meals
Prepackaged meals marketed as premium options may seem convenient and tasty, but they often contain added preservatives, stabilizers, and high levels of salt. Cooking from scratch at home is typically a more nutritionally sound choice.
When preparing meals at home, there’s more opportunity to add vegetables and whole grains for a balanced diet, something often lacking in ready-made options.
Plant Milk
Plant-based milks marketed as alternatives to dairy products vary in nutritional value, and they can be highly processed. While they can be useful for those who cannot or choose not to consume traditional milk, their long-term health effects are not well-studied compared to whole plant foods.
Meat Substitute
Similarly, meat substitutes may be processed and lack the full benefits of whole plant foods. Replacing meat in the diet can be beneficial for health, but choosing minimally processed plant-based options is key.
Meal Replacement Drinks
While meal replacement drinks can offer complete nutrition and convenience, they lack the bioactive substances found in whole foods. It’s important to incorporate a variety of foods into your diet and seek professional advice if relying heavily on meal replacements.
Breakfast Cereal
Breakfast cereals range in nutritional quality, with some being minimally processed and others high in sugar. Studies suggest that consuming breakfast cereal can improve overall nutrition, but the context of an entire diet is crucial.
Granola/Protein Bars
Bars can be convenient but are often processed and may contain excessive salt, sugar, and additives. While they can offer benefits over unhealthy snacks, they should not replace whole foods in the diet.
New research led by University of Wyoming Laramie provides additional evidence that tardigrade proteins could ultimately be used to provide life-saving treatments to people for whom refrigeration is not possible and to enhance storage of cell-based treatments.
Sanchez Martinez other. We provide insight into how tardigrades induce reversible biostasis through self-assembly of labile CAHS gels.
First discovered in 1773, tardigrades are a diverse group of microscopic invertebrates best known for their ability to survive in extreme conditions.
Also known as tardigrades or moss piglets, these creatures can live up to 60 years, grow to a maximum size of 0.5 mm, and are best seen under a microscope.
They can survive temperatures as low as -272 degrees Celsius (-457 degrees Fahrenheit) or as high as -150 degrees Celsius (-302 degrees Fahrenheit), and temperatures as low as -20 degrees Celsius for several minutes, and for up to 30 years without food or water. Masu. Minus 4 degrees Celsius (minus 4 degrees Fahrenheit) continues for decades.
Tardigrades can withstand pressures from nearly 0 atmospheres in space to 1,200 atmospheres at the bottom of the Mariana Trench, and radiation levels of up to 5,000 to 6,200 Gy.
They survive by entering a state of suspended animation called biostasis, using proteins that form gels within their cells and slow down life processes.
“Surprisingly, when you introduce these proteins into cells, they gel and slow down their metabolism, much like tardigrades do,” says researcher Sylvia Sánchez Martinez, Ph.D., of the University of Wyoming, Laramie.
“Furthermore, just like tardigrades, putting human cells with these proteins into biostasis makes them more resistant to stress, giving human cells some of the tardigrade's abilities.”
“Importantly, our study shows that the entire process is reversible,” said researcher Thomas Boothby, Ph.D., of the University of Wyoming, Laramie.
“When stress is reduced, the tardigrade gel dissolves and human cells return to normal metabolism.”
“Our findings provide an avenue to pursue technologies centered on inducing biostasis in cells and even whole organisms to slow aging and increase shelf life and stability.”

Hydrothermal vents are rich in chemicals that provide energy for animal life, fueling rich and productive ecosystems.
The location of the new hydrothermal vent was discovered by a team of scientists during a research expedition funded by the National Science Foundation.
They are located on the East Pacific Ridge near 10 degrees north latitude and are part of the trans-Earth mid-ocean ridge volcanic mountains, where two tectonic plates are breaking apart at a rate of about 11 cm (4.3 inches) per year.

The discovery has reshaped scientists’ understanding of the conditions that can support life on Earth and elsewhere in the solar system.
“Mid-ocean ridges account for more than 75% of all volcanic activity on Earth,” said CNRS researcher Dr. Thibault Valley.
“There are thousands of these deep-sea hot springs, which together extract 10 percent of the Earth’s total internal heat.”
“We want to better understand how hydrothermal vents release heat and chemicals as they flow beneath the ocean floor, impacting global oceans.”
“new guard “Using the map, we can see vital details of lava flows erupting in the deep ocean and target them for rock sample collection, just as geologists do on land.” said Dr. Daniel Fornari, a researcher at the institute.
“These new perspectives and analysis of rock samples will help us understand how fast the lava erupted, how far it traveled, and how deep-sea lava eruptions affect hydrothermal eruptions. I guess.”
“By working together these two state-of-the-art deep-sea submersibles, we will make surprising new discoveries about how the deep sea floor is constructed in some of the harshest environments on Earth. Yes, we can,” said Dr. Ross Parnell Turner., a researcher at Scripps Institution of Oceanography.
According to astronomers’ best models of black hole evolution, the magnetic field within the accretion disk must be strong enough to push the accreted plasma out into the surroundings. New results from Sagittarius A*, the 4.3 million solar mass black hole at the center of the Milky Way galaxy, and its much larger cousin M87* provide the first direct observational evidence supporting these models.
This image from the Event Horizon Telescope shows a polarized view of Sagittarius A*. The lines superimposed on this image show the direction of polarization associated with the magnetic field around the black hole’s shadow. Image credit: EHT Collaboration.
In 2022, EHT collaboration The first image of Sagittarius A*, about 27,000 light-years from Earth, has been released, showing that the Milky Way’s supermassive black hole looks very good despite being more than 1/1000th smaller and lighter in mass than M87. revealed that they are similar.
This led scientists to wonder if the two men had more in common than just their looks. To find out, they decided to study Sagittarius A* in polarized light.
Previous studies of the light surrounding M87* revealed that the magnetic field around the supermassive black hole causes powerful jets of matter to be ejected into the surrounding environment.
Based on this study, new EHT images reveal that the same may be true for Sagittarius A*.
“What we’re seeing now is a strong, twisted, organized magnetic field near the black hole at the center of the Milky Way,” said astronomers at the Harvard University & Smithsonian Center for Astrophysics. said Dr. Sarah Isaun.
“In addition to having a polarization structure that is strikingly similar to that seen in the much larger and more powerful M87* black hole, Sagittarius A* has a polarization structure that is strikingly similar to that seen in the much larger and more powerful M87* black hole. We found that strong, well-ordered magnetic fields are important for how they act.”
Light is a vibrating or moving electromagnetic wave that allows us to see objects. Light can oscillate in a particular direction, which scientists call polarization.
Polarized light is all around us, but to the human eye it is indistinguishable from “normal” light.
In the plasma around these black holes, particles swirling around magnetic field lines impart a polarization pattern perpendicular to the magnetic field.
This will allow astronomers to see in clearer detail what’s happening in the black hole region and map its magnetic field lines.
“By imaging polarized light from glowing gas near a black hole, we are directly inferring the structure and strength of the magnetic field that flows through the streams of gas and matter that the black hole feeds and ejects.” said Dr. Angelo Ricarte. Astronomer at Harvard University and the Harvard & Smithsonian Center for Astrophysics.
“Polarized light can tell us much more about astrophysics, the properties of the gas, and the mechanisms that occur when black holes feed.”
But imaging black holes under polarized light isn’t as easy as wearing polarized sunglasses. This is especially true for Sagittarius A*. Sagittarius A* changes so quickly that you can’t stand still and take a photo.
Imaging supermassive black holes requires sophisticated tools beyond those previously used to capture a more stable target, M87*.
“Sagittarius A*s are like enthusiastic toddlers,” said Avery Broderick, a professor at the University of Waterloo.
“For the first time, we see invisible structures that guide matter within a black hole’s disk, drive plasma to the event horizon, and help the plasma grow.”
“Sagittarius A* moves around while trying to photograph it, so it was difficult to even construct an unpolarized image,” said astronomer Dr. Jeffrey Bower of the Institute of Astronomy and Astrophysics, Academia Sinica in Taipei. Told.
“The first image is an average of multiple images from the movement of Sagittarius A*.”
“I was relieved that polarized imaging was also possible. Some models had too much scrambling and turbulence to build polarized images, but nature isn’t that cruel. did.”
Professor Maria Felicia de Laurentiis, University of Naples Federico II, said: “Using samples of two black holes with very different masses and host galaxies, we can determine what they agree on and what they do not agree on.” It’s important.
“Since both point us toward strong magnetic fields, this suggests that this may be a universal and perhaps fundamental feature of this type of system.”
“One similarity between these two black holes could be a jet. But while we imaged a very obvious black hole in M87*, we have yet to find one in Sagittarius A*. not.”

Parasites, especially parasitoids, are ubiquitous in extant ecosystems but poorly preserved in the geological record.
One such group is Sestoda (tapeworms), a special group of internal parasites flatworm.
These organisms have complex life cycles with at least two hosts and infect all major vertebrate groups.
However, due to its soft tissue and hidden habitat, the fossil record is very sparse, with the only widely accepted example of a pre-Quaternary period being a shark egg found in a Permian coprolite. be.
The lack of body fossils greatly hinders our understanding of early evolution.
Dr. Bo Wang, a researcher at the Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences, said: “The fossil record of tapeworms is extremely poor due to its soft tissue and endoparasite habitat, which is a major hindrance in understanding its early evolution. ''. Science.
The new fossil exhibits unique external (armature pattern) and internal (partially invaginated tentacles and rootless hooks) features that are most consistent with extant tentacles. Trypanolhynch tapeworm Parasitic substances of marine life elasmobranch (mainly sharks and rays).
“This discovery is the most convincing platyzoan fossil ever discovered,” said Dr. Cihang Luo. candidate at Nanjing Institute of Geology and Paleontology, Chinese Academy of Sciences.
“Our study provides an exceptional example of a marine endoparasite trapped in amber and also sheds new light on amber taphonomy.”
“Specifically, we showed that amber can preserve the internal structure of helminths.”
“Using high-resolution micro-CT, we discovered that inside the modern fossil, a folded vertical structure extending spirally around the longitudinal axis extends to the very front. It matches the tentacle you entered.”
“On the other hand, rootless hooks are the same as trypanorhynch hooks.”
“Previous studies have shown that internal structures can be preserved intact, similar to modern forms, but all such studies have focused on arthropods.”

“Our results show that amber can preserve the internal structure of helminths such as tapeworms over geological time scales,” Dr. Wang said.
“In addition to remarkable examples of marine endoparasites trapped in amber, several Gleichenia trichomes and scale insect larvae were also preserved in the same amber specimen along with partial insect remains. I did.”
“This clearly indicates that it was in a terrestrial or terrestrial environment at the time it was trapped in the resin.”
“Additionally, many sand grains are evenly distributed throughout the amber, suggesting that the fossil was buried in a sandy environment.”
“Furthermore, evidence so far indicates that Kachin amber was deposited in a near-shore environment.”
“One possible scenario for the tapeworm being deposited in the amber is that its elasmobranch host became stranded by tides or storms.”
“In such a scenario, the host would have been bitten by a high level of terrestrial predator or scavenger.”
“When the host was consumed by a predator, the tentacles were pulled apart, detached from the intestine, and attached to nearby resin.”
“Our study further supports the hypothesis that Kachin amber was probably deposited in a paleoenvironment in the Pala region, and also highlights the importance of amber studies in paleoparasitology.”

Recently, I was walking alone down a quiet, winding road. The road is snowy and slippery, making it difficult to walk. The sun felt warm on my face. As I trudged uphill, I missed seeing my girlfriend’s partner, but I was grateful to be able to visit my little sister, who I don’t see often.
I spent a few hours alone that day. At that time, I felt a variety of emotions, including curiosity, anxiety, and joy. It was a welcome period of solitude, and I returned to civilization feeling calmer and clearer than when I left.
Think back to the last time you were alone. Maybe you were commuting to work or getting up before the rest of your family. Maybe you live alone. Did you enjoy that period of solitude and long to connect with others, or did you let it pass without much thought?
Loneliness is inevitable. The adults inside England And the US One-third of your waking life is spent alone And it increases as you get older. In many places, we live alone more than ever before.Recent Survey of 75 countries We find that 17 of these locations have more than 25% single-person households.
As social creatures, research has historically kept us from spending time in solitude. But these days, more and more people seem to be craving time away from the crowds. Well, we now have evidence as to why spending time alone feels so good and may actually be essential to your health and well-being. Furthermore, we…
When it comes to gaming, the experience is everything. Whether you’re into Fortnite or Baldur’s Gate 3, full immersion is key, and that requires a laptop that can keep up. According to expert Eleanor Alley, who coordinates events at the University of Warwick Esports Center, the laptop you choose will depend on the specific requirements of the game you want to play. From beginners to seasoned pros, there are certain technical aspects that everyone should be aware of…
What should you consider in a gaming laptop? One crucial factor that can elevate your gaming experience is the speed of your computer. This directly impacts how smoothly the game runs and how realistic the graphics appear. Performance is influenced by three main components: the CPU (Central Processing Unit), which serves as the computer’s “brain”; RAM (Random Access Memory), which stores data required for quick access during operations, similar to short-term memory; and the GPU (graphics processing unit), which generates the images displayed on the screen.
What are the key features of a high-performance gaming laptop? Nothing is more frustrating than a game freezing at a critical moment, indicating that your computer may not meet the game’s requirements. If the CPU, RAM, or GPU are not powerful enough, loading times and frame rates will suffer. Higher frame rates result in smoother visuals, while faster loading speeds lead to seamless transitions between scenes.
When shopping for a laptop, processing power should be a top consideration. The CPU, the main processor, typically contains multiple cores that handle instructions. While a “quad-core” processor may be adequate for some laptops, those designed for gaming should ideally have 8 or more cores. For top-notch performance, a processor with 16 cores, like the newly launched Intel Core Ultra 7 and Intel Ultra 9 in the Samsung Galaxy Book4 Ultra, is recommended.
Immerse yourself in the action with high-quality audio
Increasing the amount of RAM can also enhance your gaming experience by ensuring smoother gameplay. Insufficient RAM can lead to lag, instability, and frustration. Gaming laptops should ideally have at least 16 GB of RAM, with options for more like the 32 GB available in the Samsung Galaxy Book4 Ultra.
The final piece of the puzzle is the graphics processing unit, which is essential for better visuals and gameplay. A dedicated GPU, separate from the CPU, is crucial for improved performance, especially in demanding games like Red Dead Redemption 2. The Galaxy Book4 Ultra offers two highly acclaimed NVIDIA RTX graphics options.
For Lee, the overall gaming experience hinges on the integration of these elements.
Her recommendation is to compare your system’s specifications with the game’s hardware requirements and test your favorite games on the laptop you’re considering or try out more demanding titles like Baldur’s Gate 3.
What is the ideal screen size for gaming? Lee suggests a minimum screen size of 15.6 inches, which is met by the 16-inch screen of the Galaxy Book4 Ultra. She advises opting for a screen resolution of at least 1080p and a refresh rate of 120 Hz for an enhanced gaming experience. The Galaxy Book4 series features a 3K screen resolution, providing a superior gameplay experience, especially for players who enjoy first-person games.
Modern laptops utilize AI and high-performance GPUs to create more realistic visuals. Vibrant colors and a visible touchscreen even in bright conditions further enhance the gaming experience.
Besides a great screen, top-notch audio is essential for gamers. Therefore, the inclusion of high-quality speakers and a studio-quality microphone with AI noise cancellation ensures immersive sound and minimal distractions.
How can I ensure my laptop is compatible with gaming hardware? Portability is a key aspect of laptops. However, this should not limit your ability to use various hardware such as external screens, controllers, charging docks, headsets, and other accessories. Therefore, a laptop with multiple ports is essential. The Galaxy Book4 series laptops are equipped with two Thunderbolt 4 ports, along with USB, HDMI, headphone, and microphone jacks.
What are the most important factors to consider when choosing a gaming laptop? As long as you have a capable CPU and GPU, sufficient RAM, and a quality screen, you likely have a great gaming laptop. While some may prioritize a 4K display, the graphics processor is more crucial and should be the main focus when balancing costs.
One of the advantages of laptops is their portability, as noted by Lee who values the ability to take it anywhere. In the past, this could mean compromising performance, but modern laptops maintain both portability and power.

A humanoid robot can predict one second in advance whether someone will smile and match the smile on its own face. The creators hope this technology will make interactions with robots more realistic.
Artificial intelligence is now able to imitate human language to an impressive degree, but interacting with physical robots often falls into the “uncanny valley.” One reason for this is that robots cannot reproduce the complex nonverbal cues and mannerisms that are essential to communication.
now, Hod Lipson Researchers at Columbia University in New York have developed a robot called Emo that uses AI models and high-resolution cameras to predict and attempt to reproduce people's facial expressions. It predicts whether someone will smile about 0.9 seconds in advance and smiles accordingly. “I'm a jaded roboticist, but when I see this robot, I smile back,” Lipson says.
Emo consists of a face with a camera in its eyeball and a flexible plastic skin with 23 individual motors attached by magnets. This robot uses her two neural networks. One looks at people's faces and predicts their expressions, and her other one figures out how to create expressions on her own face.
The first network was trained on YouTube videos of people making faces, while the second network was trained by watching the robot itself make faces on a live camera feed. “You learn what your face looks like when you pull all your muscles,” Lipson says. “It's like being in front of a mirror. Even if you close your eyes and smile, you know what your face looks like.”
Lipson and his team hope Emo's technology will improve human-robot interaction, but first they need to expand the range of expressions robots can perform. Lipson also wants to train his children to express themselves in response to what people say, rather than simply imitating others.
For decades, physicists have been searching for gravitons, the hypothetical particles thought to carry gravity. Although they had never been detected in space, particles like gravitons have now been observed in semiconductors. Using these to understand the behavior of gravitons could help unify general relativity and quantum mechanics, which have long been at odds.
“This is a needle in a haystack. [finding]. And the paper that started all this goes back to 1993. ” lauren pfeiffer at Princeton University. He wrote the paper with several colleagues. Aaron Pinchukdied in 2022 before finding any hint of the elusive particle.
Pinchuk's students and collaborators, including Pfeiffer, have completed the experiment they began discussing 30 years ago. They focused on electrons within a flat piece of the semiconductor gallium arsenide, which they placed in a powerful refrigerator and exposed to a strong magnetic field. Under these conditions, quantum effects cause electrons to behave in strange ways. The electrons interact strongly with each other, forming an unusual incompressible liquid.
Although this liquid is not gentle, it is characterized by collective motion in which all the electrons move in unison, which can lead to particle-like excitations. To investigate these excitations, the team illuminated the semiconductor with a carefully tuned laser and analyzed the light scattered from the semiconductor.
This revealed that the excitation contains a type of quantum spin that had previously been theorized to exist only in gravitons. This isn't a graviton itself, but it's the closest thing we've ever seen.
Liu Ziyu The professor at Columbia University in New York who worked on the experiment said he and his colleagues knew that graviton-like excitations could exist in semiconductors, but they needed to make the experiment precise enough to detect it. He said it took many years. “From a theoretical side, the story was kind of complete, but the experiments weren't really convincing,” he says.
This experiment is not a true analog of space-time. Electrons are confined in flat, two-dimensional space and move more slowly than objects governed by the theory of relativity.
But he says it is “hugely important” and bridges various previously underappreciated areas of physics, such as materials physics and the theory of gravity. Kun Yan from Florida State University was not involved in this study.
but, Zlatko Papik Researchers at the University of Leeds in the UK cautioned against equating the new discovery with the detection of gravitons in space. He said the two are equivalent enough for electronic systems like the one in the new experiment to serve as a testing ground for theories of quantum gravity, but they are not equivalent for all quantum phenomena that occur in space-time on a cosmic scale. It says no.
This connection between particle-like excitations and theoretical gravitons also yields new ideas about exotic electronic states, team members say. de Linjie At Nanjing University, China.
Europe’s longest Hyperloop test line opening has once again sparked hopes for a future that combines maglev and vacuum tube transportation technologies.
Operators believe that this facility will demonstrate the feasibility of Hyperloop, paving the way for a high-speed tube network spanning 6,200 miles (10,000km) across the continent by 2050.
Currently, the testbed at the European Hyperloop Center in Veendam is a 420-meter-long bifurcated white pipe running alongside a track and road, not yet transporting people in the Netherlands.
The test pipe, constructed from 34 connected 2.5-meter-wide prefabricated steel cylinders, partially funded by the EU, falls short of the envisioned two-mile track for 2020 due to speed limitations. The goal is to achieve the required 620 mph (1,000 km/h) in the future.

The Vandeem pipe’s fork will be instrumental in testing “lane switching” during high-speed vehicle course changes, with initial tests conducted by Hard Hyperloop in the Netherlands.
The center’s director, Sacha Lam, hailed this development as a pivotal moment, envisioning a pan-European network with infrastructure branching to various destinations like Paris and Berlin.
The concept of the Hyperloop was introduced by Elon Musk in 2013, proposing a line between San Francisco and Los Angeles. This innovative transportation method could revolutionize travel speed and efficiency.
Despite past setbacks, such as Hyperloop One’s bankruptcy, proponents like Sacha Lam see a bright future where a European Hyperloop network could become a reality within decades, offering a cleaner, quieter, and faster mode of transportation.
This innovative technology could help Europe catch up with pioneering developments in China, where a “low-vacuum pipeline magnetic levitation technology” test track was unveiled in 2022.
Antibodies are proteins that can target and attack specific cells.

An experimental treatment rejuvenates the immune systems of older mice and improves the animals’ ability to fight infections. If this treatment is effective in humans, it could reverse the age-related decline in immunity that makes older people more susceptible to illness.
These reductions may be due to changes in blood stem cells, which can develop into all types of blood cells, including important components of the immune system. As we age, a greater proportion of these stem cells tend to produce some immune cells than others. Jason Ross at Stanford University in California. This imbalance impairs the immune system’s ability to fight infection. It also promotes chronic inflammation, which accelerates aging and increases the risk of age-related diseases such as heart disease, cancer, and type 2 diabetes.
Ross and his colleagues have developed a treatment that uses antibodies, proteins that recognize and attack specific cells, to target these biased stem cells. Next, they tested the treatment on six mice aged 18 to 24 months. This is roughly equivalent to a human being between 56 and 70 years old.
One week after receiving the antibody injection, these abnormal stem cells in the mice had decreased by about 38 percent compared to six rodents of the same age who did not receive treatment. They also had significantly higher amounts of two types of white blood cells important for recognizing and fighting pathogens, and lower levels of inflammation.
“You can think of this as turning back the clock,” says Ross. “We are adjusting these percentages [immune] more similar cells [those of] A young adult mouse. ”
To test whether these changes result in a stronger immune system, the researchers vaccinated 17 older mice with a mouse virus. Nine of these mice had received antibody treatment eight weeks earlier. The researchers then infected rodents with the virus. After two weeks, the number of infected cells in the animals was measured and it was found that almost half of the treated mice (4 out of 9) had completely cleared the infection, compared to 1 out of 8 of the untreated mice. It turned out that there was only one.
Taken together, these findings demonstrate that antibody treatment rejuvenates the immune system of aged mice. Humans, like rodents, have more abnormal blood stem cells as they age, so a similar antibody treatment could also boost their immune systems, Ross said.
Such a possibility is still far away, robert signer at the University of California, San Diego. First, we need a better understanding of the potential side effects of treatments. In an accompanying article, Signer and his colleagues write: Yasar al-Fat KassResearchers, also at the University of California, San Diego, suggest that depletion of stem cells, even abnormal stem cells, may increase cancer risk. On the other hand, “if you have a better immune system, you’ll be better at investigating cancer, so we don’t know exactly what will happen yet,” Signer says.
Still, Ross says these findings are a promising advance in understanding age-related immune decline and how to reduce it.
Aging is the biggest risk factor for various diseases. “Rejuvenating or improving immune function in older adults could really help fight infectious diseases,” Signer says. “It may also have an impact on different types of chronic inflammatory diseases. That’s what’s so exciting here.”

Using data from ESA’s ExoMars Trace Gas Orbiter and NASA’s Mars Reconnaissance Orbiter, planetary scientists created a 1:30,000-scale geological map of the Oxian Plain, the landing site for ESA’s ExoMars Rosalind Franklin rover mission. Created.

Oxia Planum Located on the northern edge of Arabian Terra, it preserves a record of the diverse geological processes that shaped the region.
It is a transitional region between the cratered Arabian Terra and the young lowland plain of the Chryse Planitia.
“Oxia Planum is located near the Martian equator and contains deposits that are nearly 4 billion years old,” said Open University researcher Peter Faudon and colleagues.
“On a geological scale, this would be the oldest landing site ever visited by a spacecraft on Mars.”
“This region is rich in clay minerals that form due to the presence of water. These rocks are ideal for preserving evidence of the earliest forms of life. This makes it possible to predict that life once existed on Mars. It’s a great place to look for clues as to whether this is the case.”
To map the Oxian Plains, the authors used several instruments, including the Color and Stereo Surface Imaging System (CaSSIS) onboard the ExoMars Trace Gas Orbiter and the HiRISE camera on NASA’s Mars Reconnaissance Orbiter (MRO). We used data from.
This map details 15 rock units classified into 6 groups and 7 textural and surface units.
“This map includes the main types of rock and structures with unique shapes, such as ridges and craters,” the researchers said.
“It also features materials that are placed on top, blown by the wind or blown long distances when a meteorite hits the Earth’s surface, for example.”
The result is the highest-resolution map of the Oxian plains to date at a scale of 1:25000, where 1 centimeter corresponds to 250 meters on the surface of Mars.
Average daily driving time is 25-50 minutes. rosalind franklin rover On the map it is 1-2 mm.
“This map is really interesting because it’s a guide to where the answers are,” Dr. Faudon said.
“This serves as a visual hypothesis for what we currently know about the different rocks at the landing site.”
“With the instruments on board the Rosalind Franklin rover, you can test your knowledge on the fly when the time comes.”

Global warming is causing the Earth’s rotation to slow slightly, which could affect the way we measure time.
A study published Wednesday found that the melting of polar ice, a trend accelerated primarily by anthropogenic climate change, is causing the Earth to spin more slowly than it would otherwise.
Study author Duncan Agnew, a geophysicist at the Scripps Institution of Oceanography at the University of California, San Diego, said melting polar ice changes where the Earth’s mass is concentrated. This change affects the planet’s angular velocity.
Agnew likened the dynamic to a figure skater spinning around on ice. He said, “If a skater starts spinning and lowers his arms or extends his legs, he will slow down.” However, if the skater’s arms are pulled inward, the skater will rotate faster.
So less solid ice at the poles means more mass around the equator, at the Earth’s waist.
“What melting ice does is take water that has solidified in places like Antarctica or Greenland, and when that frozen water melts, it moves that liquid to other parts of the planet. “Thomas Herring said. He was a professor of geophysics at the Massachusetts Institute of Technology but was not involved in the new research. “Water flows toward the equator.”
In other words, this study shows how human influence can successfully manipulate forces that have puzzled scholars, stargazers, and scientists for millennia: forces long thought to be constants beyond human control. It suggests that it has happened.
“It’s kind of impressive, even to me, that we were able to accomplish something that measurably changed the rotational speed of the Earth,” Agnew said. “Something unprecedented is happening.”
His research, published in the journal Nature, suggests that climate change is playing a significant enough role in the Earth’s rotation to delay the possibility of a “negative leap second.” If the polar ice hadn’t melted, clocks around the world might have needed to subtract one second by 2026 to synchronize universal time with the Earth’s rotation, which is influenced by a variety of factors.
Rather, the impact of climate change has delayed that outlook by an estimated three years. If timekeeping organizations ultimately decide to add negative leap seconds, the adjustment could disrupt computer networks.
A view of the Earth captured by a deep space climate observation satellite.NASA
The leap second adjustment is necessary because even without climate change, the Earth’s daily rotation tends to slow down over time, even though it appears constant.
Studies show that about 70 million years ago, days became even shorter, lasting about 23.5 hours. Implications of paleoceanography and paleoclimatology. This means that Cretaceous dinosaurs experienced 372 planetary days a year.
Several important factors influence a planet’s rotation, but they sometimes act in opposition.
Due in part to the moon’s gravitational pull, tidal friction in the oceans slows the Earth’s rotation. Meanwhile, since the last Ice Age, the Earth’s crust has been uplifting in some areas in response to the removal of ice sheet weight. This effect changes the distribution of mass, causing the planet to spin faster. Both of these processes are approximately constant and have predictable rates.
Yet another factor is the movement of fluids within Earth’s liquid inner core, a wild card that can either speed up or slow down Earth’s rotation, Agnew said.
Here, melted polar ice was added to the mix. As climate change intensifies, researchers expect melting ice to have an even more profound effect on the Earth’s rotation.
“As we predict, as melting accelerates over time, its contribution will become even larger,” Herring said. He added that the new study is a thorough and robust analysis that combines research from multiple scientific fields.
The need for timekeepers to adjust universal time to match the Earth’s rotation is not a new phenomenon. But historically, this involved adding leap seconds to the common standard for clocks. This is because astronomical time lags behind atomic time (measured by the vibrations of atoms in atomic clocks) due to the slowing of the Earth’s rotation.
But in recent decades, changes in the Earth’s core have caused the Earth to rotate faster than expected. This has led timekeepers, for the first time since Coordinated Universal Time was officially adopted in the 1960s, to consider whether it makes sense to subtract leap seconds to synchronize universal time with the Earth’s rotation. Ta.
The melting of polar ice counteracted that trend, avoiding any decision points regarding negative leap seconds. According to Agnew’s estimates, if the current rate of Earth’s rotation is maintained, it will likely be delayed by three years from 2026 to 2029.
Adding or subtracting leap seconds is troublesome because it can disrupt satellite, financial, and energy transmission systems that rely on very precise timing. For that purpose, Timekeepers around the world have voted to abolish leap seconds in 2022. By 2035, addition and subtraction will shift universal time from the pace of the Earth’s rotation.
“Since around 2000, there has been a movement to abolish leap seconds,” Agnew said.
Regardless of whether the clocks ultimately change, the idea that melting polar ice is affecting the Earth’s rotation speaks to how important an issue it has become. Studies have already shown that ice loss has significant impacts on coastal communities.
Scientists predict that sea level rise will accelerate as the climate warms, a process that will continue for hundreds of years. Last year, leading polar researchers warned in a report that parts of the major ice sheets could collapse and coastal regions should brace for several feet of sea level rise. If humans allowed global average temperatures to rise by 2 degrees Celsius, Earth could see sea levels rise by more than 40 feet.
I love how games keep me so occupied that I think about them all day long while living my real life. This doesn’t happen a lot these days because I’ve played so many games over the past 30 years. It happens when a game does something I’ve never seen before. For example, last year’s The Legend of Zelda: Kingdom of Tears featured a reckless gimmick. Or sometimes it’s because of something I do, like Dragon’s Dogma 2, which I’m still playing after reviewing last week. We’ve seen it before, but not for very long.
In the 12 years between the original Dragon’s Dogma and this sequel, Elden Ring is the only game that has come close to recapturing that brand of fantasy action role-playing with its chaotic, stubborn idiosyncrasies. This is a game where you can ruin a quest by fooling around for too long before pursuing the next objective. On an otherwise empty journey through the countryside, a griffin can appear and run you over to death almost instantly. The multidimensional beings who act as your companions on your journey contract a mysterious disease that unleashes the apocalypse when you save the game. You only have one save slot, so every decision counts. If you make a mistake, you have to accept it.
While some players have had disappointing reactions to the game’s inflexibility, I respect Dragon’s Dogma 2’s willingness to ruin your day at times. It will not bend to your will. You need to work around the rules, even if you don’t necessarily know what they are at first. At first, you might be annoyed that characters often tell you about interesting legends and rumors, but the game also marks them on the map to show you where they are likely to be found. And over time, when you are left out in the wilderness at night, without camping gear, and try to take shelter in a cave which leads to a crumbling mountain shrine, you may find a real Sphinx there. You realized that even if someone had marked the location on your map, you would never have done that. You must have been in awe the first time you saw those glowing eyes in the dark.
Conventional wisdom in open-world games has long held that games are structured like to-do lists. A character with an icon above their head will appear, they will give you something to do, and the game will conveniently mark the location and start checking boxes before receiving the reward. The map is full of small icons that show you where to find things you might need to upgrade your equipment or further your objectives. In recent years, games like Zelda: Breath of the Wild and Elden Ring have ditched these conventions, making their worlds feel once again mystical, realistic, and dangerous, but not Dragon’s Dogma 2.
The appeal of Dragon’s Dogma 2 is that it is less susceptible to external influences. Dragon’s Dogma 2 feels like the development team has spent the last decade or more playing only their own games. It’s appealingly free from outside influences and doesn’t adopt any of the ideas that other games have become standard for since 2012. For example, you cannot use menus to fast-traverse the map, except in a few rare cases. If you want to go somewhere, you have to walk. For many years.
You follow that path and if you stray from it, you’re very likely to run into something that will kill you. But you’ll also have adventures like when I found a haunted castle full of skeletons. By the time you and your team reach your next town as the night draws on, exhausted and full of trinkets you picked up along the way, you’ll feel like you’ve actually accomplished something. One way to get around on foot is by riding an oxcart. This takes even more time than incredible walking, unless the character falls asleep and wakes up at the destination. Also, during your journey, you may be attacked by monsters, destroy your entire cart, and end up stranded in a strange land in the middle of the night. It’s like a cruel joke.
What all of this gives the player is what I would describe as a feeling of being fully awake. You can’t switch off your brain when playing games like this. With no minimap or quest markers to tell you where to go, you have to remember what people say, use your eyes to read your way, and find things in the distance. You must be ready to fight when called upon, and be ready to run for your life when cornered. I keep seeing things I’ve never seen before.
Games like this have periodically pulled me out of my funk over the decades, reminding me that they can still be exciting and unpredictable. Regular reader Iain wrote the question last week that was part of the impetus for this issue. “As a gamer in my late 70s, I’ve been playing games since 1985. I think I’ve reached a point where I’ve seen it all before. Are there truly innovative titles, or do they stick to the ongoing series (some of which reach double digits)?” Well, Ian, for me Dragon’s Dogma 2 is one of those games that restores my faith. It may be a sequel, but it hasn’t been this great yet.
It has been close to two years since the world was first introduced to Sagittarius A* (Sgr A*), the supermassive black hole residing at the center of the Milky Way.
A true behemoth, Sgr A* boasts a mass equivalent to 4 million suns and is encircled by hot pockets of swirling gas. Despite its immense size, it sits about 27,000 light-years away from Earth, appearing in the sky only as large as a donut on the moon’s surface.
In a recent study published in the Astrophysics Journal Letter and released by the event horizon telescope (EHT), Sgr A* was captured in polarized light for the first time.
Similar to how sunglasses can filter polarized light from the sun, astronomers utilize polarized light to unveil concealed magnetic fields.
The lines within the image indicate the direction of polarization, which correlates with the structure of the magnetic field surrounding the black hole.
“The spiral pattern observed swirling around the black hole signifies that the magnetic field must also be swirling, indicating a very strong and ordered field,” stated Dr. Sarah Isaun, an Einstein Fellow and co-leader of the project in the NASA Hubble Fellowship Program, as quoted in BBC Science Focus.

The first-ever image of a black hole was unveiled by EHT in 2019, featuring a much grander black hole at the core of the Messier 87 galaxy (M87*).
M87* is approximately 1,000 times heavier than Sgr A*, leading to a slower rotation making it easier to image.
Further developments include astronomers releasing images of the magnetic field encompassing M87* in 2021. Overcoming the challenge of capturing our own supermassive black hole in polarized light took an additional three years.
In a surprising revelation, despite the contrasting sizes of the two black holes, the new images demonstrate strikingly similar magnetic field structures, emphasizing the prevalence of strong magnetic fields in both. This highlights a fundamental feature of supermassive black holes.
Isaun emphasized, “Sgr A* now holds a polarization structure remarkably akin to the larger, more potent M87* black hole, supporting the significance of a robust, well-ordered magnetic field in these entities.”

Previous investigations on M87* disclosed that the encircling magnetic field generates potent jets of energy and matter extending far beyond the galaxy. While astronomers have visualized the jet around M87*, it has remained elusive around Sgr A*. However, recent images unveil remarkable similarities between the two black holes, suggesting the potential existence of jets in both.
Isaun highlighted, “The jets within the host galaxy can stimulate or counteract star formation, exhibiting a fascinating interplay between the dynamics of these emanating jets from these black holes and the evolvement of the host galaxy. There exists a connection.”
“I believe we can extract valuable insights into our galaxy’s history from this connection.”

The upgraded EHT is set to observe Sgr A* once more next month, with astronomers hopeful of uncovering concealed jets and other facets of the galaxy’s central region.
Anticipate further groundbreaking revelations from EHT, potentially including more awe-inspiring images and even real-time video footage in years to come.

TFor a kid growing up in Britain in the 1980s, the Atari 400 and 800 machines seemed incredibly appealing. Most of my friends had a Commodore 64 or ZX Spectrum (occasionally he also used an Amstrad or Acorn Electron), but I only saw Atari computers in cool TV shows and movies like Videodrome and Police Story. That never happened. These two models, released in 1979, featured an Antic video processor that provided excellent graphics for the time, and a sound chip named Pokey to improve audio. These, like the Apple II, were seminal machines for young game programmers looking to create new types of experiences beyond simple arcade conversions.
Opening up the new Atari 400 Mini was a strangely emotional experience. The latest nostalgic release from Retro Games is an exquisitely detailed recreation of the original computer, featuring a non-functional version of the famous membrane keyboard in luscious 1970s beige, orange, and brown. It has 4 joystick ports (currently rather USB) (from the original Atari joystick port standard). The console comes with a new version of the classic Atari CX40 joystick, with the subtle addition of eight buttons that can now summon the keyboard to provide additional input options in Atari 400/800 games. Masu.
It includes 25 games that show the range of what was being produced on the 400 and 800 (the 800 was a higher-end model with more memory and a better keyboard) in the early 1980s. There are quaint home versions of classic arcade titles like “Asteroids,” “Millipede,” and “Battlezone,” which are, after all, what home console and computer developers had to do at the time. It’s a fascinating reminder of the compromises that weren’t made. And there are many more to come, including Capture the Flag, Paul Allen Edelstein’s two-player first-person tracking game, and his MULE, a multiplayer colonial strategy game that influenced the entire management simulation industry. You can get a glimpse of the genre.
There’s also some interesting experimentation in creating fast-paced 3D visuals in the form of futuristic racing sims Elektra Glide and Encounter. Written by Paul Woakes, who later went on to create one of his most fascinating 3D sci-fi adventure titles of this era, Mercenary.
Some games will be familiar to anyone who bought a C64 Mini or other retro machine, but the Atari 400 version was often the first to be released, so you get the primary source material here. Well almost. Although there is no original hardware used, the emulators that Retro Games employs to run all these games are robust and accurate, allowing them to recreate these 40-year-old gems very well.

And while they’re definitely older, many of these titles, including Boulder Dash and Lee (originally titled by Bruce Lee, whose license has probably expired), remain as truly playable relics. Saved. Either way, I’ve had many hours of fun discovering games I’ve never seen before, as well as familiar favorites in various guises. Additionally, in typical mini-console style, there is a rewind feature to fix mistakes, and the game can be saved to memory. You can also fine-tune your visual settings and choose CRT effects that mimic the display style of a traditional TV. A virtual keyboard is also available if you want to play games that require more input options. It’s not always easy to use, but it’s nice to be able to use it when necessary.
Interestingly, one of the 400 Mini’s selling points is its ability to “load your own programs.” This is a euphemism in the instruction manual for the console to play game files known as ROMs, which can be loaded via a USB stick. Most people will find these ROMs on the internet, but the legality of freely downloading game files is murky to say the least. So Retro Games leaves it up to you to figure this out. I ran a few games to test this aspect and it was a surprisingly smooth process. The emulator accepts files in many popular formats and plays both Atari 400 and 800 titles, as well as his later XL/XE variations. When you insert a USB stick with game ROMs, you’ll see a thumb drive icon in the games list on the screen, and clicking on it will show the games you’ve added. The system also supports games that originally appeared on multiple discs. Additionally, you can reconfigure the joystick buttons to suit the input requirements of most games you’re trying out.

At £100, the 400 Mini isn’t cheap, and the game is a great choice for new players who prefer their Mega Drive or PC Engine Mini machines with their attractive 16-bit visuals and familiar series. It may not be appealing. But as an accessible museum piece, it’s a fascinating and well-made device that reveals games you’ve never played in its original form, as well as an entirely fresh retro experience. This industry has always failed to protect its heritage and history. Official archives are often exposed and inaccessible. The Mini Console is a small attempt to address this issue in an intuitive and well-chosen format.
I’m a long way from that kid growing up in the 1980s now, but finally playing these Atari 400 gems reminded me of him and what he was fascinated by. That in itself gives value to this little machine.
This is a supermassive black hole at the center of a galaxy that we have never seen before. The image reveals a swirling magnetic field around Sagittarius A* (Sgr A*), suggesting it may be producing jets of high-energy material that astronomers have not yet seen.
This photo was taken by a network of observatories around the world operating as a single giant telescope called the Event Horizon Telescope (EHT). In 2022, the first images of Sgr A* were produced, revealing light emanating from swirling hot plasma set against the dark background of a black hole's event horizon. There, light cannot escape the extreme gravity.
Now, EHT researchers Jiri Yunshi The researchers from University College London measured how this light is polarized, or the direction of the electromagnetic field, and showed the direction and strength of the magnetic field around Sgr A*.
This image is very similar to the magnetic field of M87*, the first black hole studied by EHT. Given that M87* is about 1,500 times more massive than Sgr A*, this suggests that supermassive black holes may have similar structures regardless of their size, Yunshi says.
The two black holes photographed by the Event Horizon Telescope are strikingly similar.
European Southern Observatory (ESO)
One major difference between M87* and the black holes in our galaxy is the absence of visible high-energy jets visible from Sgr A*. This lack has long puzzled astronomers, but the fact that Sgr A* has a magnetic field like M87* suggests that our galaxy's black hole may also have jets. It suggests.
“There are very interesting hints that there may be additional structures,” Yunshi says. “I think something very exciting could be happening at the center of the galaxy, and we need to track these results.”
This makes sense given other evidence for jets that may have existed long before the galaxy's history, such as Fermi bubbles, large balls of X-ray-producing plasma above and below the Milky Way. Masu.
In addition to revealing potential hidden jets, the properties of magnetic fields also solve other astrophysical mysteries, such as how particles like cosmic rays and neutrinos are accelerated to ultrahigh energies. This could help solve the problem, Yunshi said. “Magnetic fields are the basis of all of this. Anything that yields further insight into how black holes and magnetic fields interact is of just fundamental importance to astrophysics.”
Yunshi and his colleagues hope to use a larger telescope network and more advanced equipment to take more images of Sgr A*, which will help them understand the nature of the magnetic field and how it directs the jet. This will deepen your understanding of what is being generated. EHT plans to begin these observations in April, but processing the data could take several years.
SAm Bankman Fried, the former CEO of bankrupt cryptocurrency exchange FTX, oversaw a dramatic collapse that led to losses of billions of dollars for customers. In a court filing, he claims that all debts owed by FTX will be fully repaid. However, the US government views his statements as disconnected from reality.
Last week, FTX administrator John Ray III, appointed to manage the bankruptcy proceedings, accused Bankman Fried of orchestrating a massive fraud and living in a state of delusion. Ray dismissed the claims made by Bankman Fried’s lawyer that no one suffered harm as “categorically, callously, and patently false.”
Banker Mann Fried faces sentencing tomorrow after being convicted of fraud and money laundering conspiracy in the collapse of his cryptocurrency exchange. His potential 100-year prison sentence contrasts with a requested six-year term from his lawyer. The US government seeks a 40 to 50-year sentence for the 32-year-old former CEO who defrauded customers of $8 billion.
The Justice Department asserts that Bankman-Fried’s attempts to downplay his crimes and seek a lighter sentence reveal a dangerous potential for future fraud. The disputed bankruptcy proceedings for FTX may continue long after his release.
FTX: New technology, old embezzlement
This crypto entrepreneur created a façade of philanthropy by using client funds for personal luxuries, influencing political figures, and promoting the pseudo-altruistic philosophy of effective altruism. Recent testimonies have labeled FTX’s collapse as traditional embezzlement.
During the trial, evidence showed that $11.3 billion meant for customers was only $2.3 billion, with the rest diverted to investments, political contributions, and real estate, with little financial record-keeping. Wray likened the situation to a severe disaster caused by Bankman Fried’s deception.

The danger of aging explosives from unexploded ordnance is increasing
Gail P. Novik (2024)
A study of unexploded ordnance from World War II found that one of the explosives it contained had become shock-sensitive and could ignite if dropped during disposal. The explosive, called Amatol, was widely used during World War I and World War II and is still included in some of the ammunition used during Russia's war in Ukraine.
“Based on our findings, we can say it's relatively safe to handle, but you can't treat it like TNT,” he says. Gail Petter Novik At the Norwegian Defense Research Establishment. “In contrast to TNT, it can definitely explode if dropped.”
There are millions of tons of unexploded ordnance around the world, some in old ammunition dumps and some in shells and bombs that did not explode after being fired or dropped. Novick said there is a widespread misconception that unexploded ordnance becomes less dangerous over time. In a 2022 study, he examined samples of TNT and PETN, two of the most widely used high explosives, taken from World War II bombs and shells. test and There was no deterioration in explosive properties..
He has now tested the impact sensitivity of five samples of Amatol taken from unexploded World War II bombs and artillery shells found in Norway. The test involved dropping weights from various heights on small samples to see what would explode. All five samples were more sensitive to shock than expected with Amatol, and one sample was four times more sensitive.
Novick says this discovery will change the way he and his team deal with unexploded ordnance. For example, when clearing a dump, fewer volumes are transported at once. He now plans to find out why shock sensitivity has increased. “We think sensitive crystals or salts may have formed,” he says.
This may be the result of contaminants from the manufacturing process, or reactions with the metal case as the lining deteriorates, or simply due to aging.
Amatol is the name used to describe an explosive made from a mixture of TNT and ammonium nitrate. It was developed by Britain's Royal Arsenal in 1915 when TNT was in short supply. As TNT production increased at the end of World War II, many countries stopped using Amatol, although it continued to be used in countries such as the Soviet Union. “Several types of Soviet-era ammunition currently in use in Ukraine are known to contain Amatol,” Novik said.
It's impossible to say what percentage of the world's unexploded ordnance contains amatol, he says. But five of the 20 bombs and shells he cut open for this study contained the substance, and so did most of the World War II unexploded ordnance he examined. has been found.
Accidents in which unexploded ordnance explodes also occur frequently.For example, in 2023, World War II bombs Explosion at Great Yarmouth Currently being disposed of in the UK. In 2004, new scientist A US ship that sank in the Thames Estuary was carrying 1,400 tonnes of high explosives and posed a serious threat to nearby towns, an unpublished risk assessment has revealed. A 2023 survey of the ship found plans to remove the mast could be dangerous and were postponed.
Considering the importance of sleep to our mental and physical health, Balter and John AxelsonAt Karolinska Institutet, we also decided to investigate whether it affects our subjective age.
They surveyed 429 people between the ages of 18 and 70 about how old they felt and how much sleep they had gotten in the past 30 days.
The researchers found that reporting sleep deprivation was associated with participants feeling older than their actual age, with consecutive days of sleep deprivation making participants feel older by an average of 0.23 years. was found to increase. In contrast, those who reported getting enough sleep over a 30-day period were, on average, 5.81 years younger than their chronological age.
In the second half of the study, the pair recruited an additional 186 people. These participants were asked to aim for 9 hours of sleep over two consecutive nights over a two-week period, which was recorded via a sleep log and sleep tracking wrist device. They were then told to limit their sleep to four hours for two consecutive nights.
After this period of sleep restriction, subjects reported feeling on average 4.44 years older than their age, whereas under the 9-hour sleep condition they reported feeling 0.24 years younger. Compared to those who felt the least fatigued, those who felt the most fatigue reported feeling about 10 years older.
The findings show that sleep is an important indicator of how old some people feel, and that it is linked to our health, Balter says. “If you protect your sleep, you'll feel younger,” she says.
According to physicists, CMS cooperation This is the first time this process has been observed in proton-proton collisions at CERN's Large Hadron Collider (LHC). This is also the most accurate measurement of tau's anomalous magnetic moment and provides a new way to constrain the existence of new physics.
We reproduced candidate events of the γγ →ττ process in proton-proton collisions measured by the CMS detector. Tau can decay into muons (red), charged pions (yellow), and neutrinos (not visible). Energy is stored in green in an electromagnetic calorimeter and cyan in a hadronic calorimeter. Image credit: CMS Collaboration.
of TauIt is a special particle of the lepton family, also called tauon.
In general, leptons, together with quarks, constitute the matter content of the Standard Model.
Tau was first discovered in the 1970s, and its associated neutrino (tau neutrino) was discovered by Fermilab's DONUT collaboration in 2000 to complete the tangible matter part.
However, tau has a very short lifetime and can remain stable for only 290*10 hours, making it quite difficult to study it accurately.-15 seconds.
Two other charged leptons, electrons and muons, are fairly well studied.
Much is also known about their magnetic moments and their associated anomalous magnetic moments.
The former can be understood as the strength and direction of a virtual bar magnet within the particle.
However, this measurable quantity requires correction at the quantum level resulting from the virtual particles pulling on the magnetic moment and deviates from the predicted value.
The quantum correction, called the anomalous magnetic moment, is about 0.1%.
If the theoretical and experimental results do not agree, this anomalous magnetic momentIopens the door to physics beyond the Standard Model.
The anomalous magnetic moment of the electron is one of the most accurately known quantities in particle physics and is in perfect agreement with models.
Its muon counterpart, on the other hand, is one of the most studied, and research is ongoing.
So far, theory and experiment are largely in agreement, but recent results raise tensions that require further investigation.
But for Tau, the race is still on. Its anomalous magnetic moment is particularly difficult to measure.τThis is because tau has a short lifespan.
The first attempt wasτ After the discovery of tau, there was an uncertainty 30 times higher than the size of the quantum correction.
Experimental efforts at CERN improved the constraints and reduced the uncertainty to 20 times the size of the quantum correction.
In collisions, physicists look for special processes. That is, two photons interact to produce two tau leptons (also called a ditau pair), which then decay into muons, electrons, or charged pions, and neutrinos.
So far, both ATLAS and CMS collaborations have observed this in ultraperipheral lead-to-lead collisions.
Now, CMS physicists report: first observation The same process occurs during proton-proton collisions.
These collisions provide greater sensitivity to physics over the standard model, as new physical effects increase with collision energy.
Taking advantage of the superior tracking capabilities of the CMS detector, the collaboration will isolate this particular process from other processes by selecting events that produce a tau with no other tracking within a distance of just 1 mm. I was able to separate it.
“This remarkable achievement in detecting proton-proton collisions in the super-periphery sets the stage for many breakthrough measurements of this kind from CMS experiments,” said Dr. Michael Pitt, a member of the CMS team. said.
This new method provided a new way to constrain tau's anomalous magnetic moments, and the CMS Collaboration quickly put it to the test.
Future driving data will likely improve the significance, but their new measurements impose the tightest constraints to date, with greater precision than ever before.
This reduces the prediction uncertainty to just three times the size of the quantum correction.
“We're really excited to finally be able to narrow down some of the fundamental properties of the elusive tau lepton,” said CMS team member Dr. Isaac Neutelings.
“This analysis introduces a new approach to investigating tau g-2 and revitalizes a measurement that has been stagnant for more than 20 years,” said CMS team member Dr. Xuelong Qin.
A team of paleontologists from California State Polytechnic University and others has described a new genus and species of shark-like fish from the Fayetteville Shale in late Mississippi, Arkansas.

The newly described species lived in the Devonian seas, about 326 million years ago.
named Cosmoserax meringii This is one of many well-preserved shark fossils discovered from oil-producing seas. fayetteville shale formation Stretching from southeastern Oklahoma to northwestern Arkansas, it has been studied for many years for its well-preserved invertebrate and plant fossils.
“These creatures are part of an ecosystem that recovered after the mass extinction of fish communities at the end of the Devonian period, so they're part of the cartilaginous fish family, which includes all sorts of strange anatomy not seen in modern sharks. We're at a point where the morphological diversity of the species is astonishing,” said Dr. Alison Bronson, a researcher at California State Polytechnic Institute.
fossil of Cosmoserax meringii It was collected by Professors Royal and Gene Mapes of Ohio University in the 1970s.
Dr. Bronson and his colleagues performed a CT scan of the specimen and digitally reconstructed it.
They spent months studying to describe its anatomy, which includes dozens of tiny pieces of cartilage.
Once the reconstruction is complete, they Cosmoserax meringii In the early cartilaginous fish tree of life.

The authors found that this new species plays an important role in understanding the evolution of a mysterious group called green sea turtles. Shinmori form.

To safely observe a solar eclipse, you’ll need some basic equipment

If you’re planning on observing the solar eclipse on April 8 this year, whether you’re in the middle of the total solar eclipse or not, you’ll need some gear to fully enjoy it.
The most important rule during a solar eclipse is not to look directly at the sun. This is only possible during totality, a few minutes when the sun’s light is completely blocked by the moon. But for everyone in North America who lives outside the 185-kilometer-wide total orbit, only a partial eclipse will be visible. And for those on the inside of the road, there are still a few hours on either side of totality, but part of the fun is watching the moon slowly move across the sun.
You can use special solar filters, such as eclipse glasses, to look directly at the sun. But you can also view the eclipse using a simple viewer made from a few things you probably have on hand. Here we will introduce how to create two types of Eclipse viewers.
How to make a pinhole camera
All you need for this viewer is paper, aluminum foil, scissors, and a pen. Make a hole in the middle of a piece of paper and cover with foil. Stick the foil in place and use a pen, needle, or other sharp object to make a small hole in the center of the foil. On the day of a solar eclipse, simply hold this up to the sun and place another piece of paper on the ground below. A small bright dot appears on the second sheet of paper. This is a solar projection. As the eclipse progresses and the moon covers more of the sun, you’ll see the shape of the dot change.
How to make a box eclipse viewer
The second type of eclipse viewer works similarly, but the projection is displayed inside a box instead of on the ground. For this, you will need paper, foil, scissors, and a cardboard box. Cereal boxes or shoe boxes work well.
Line one side of the inside of the box with white paper. Then, drill two holes, spaced apart on opposite sides. Tape the foil to one hole and make a small hole in it. The other hole will be a place to look inside.
On the day of the solar eclipse, hold the viewer in front of you with your back to the sun. A projection of the sun should appear on the white paper lined inside the box.

On April 8th, a total solar eclipse will pass over Mexico, the United States, and Canada. Our special series covers everything you need to know, from how and when to see a solar eclipse to the strangest solar eclipse experience of all time.
Dairy cows in several US states have reportedly contracted bird flu. United States Department of Agriculture (USDA). The virus has killed millions of birds around the world, but this is the first time it has been detected in cattle.
How many cows are affected by avian influenza?
As of March 25, milk samples from two dairy farms in Kansas and one in Texas tested positive for the avian influenza subtype called H5N1. new york times. This strain is highly lethal to birds. A cow throat swab taken from a dairy farm in Texas also tested positive. So far, no cows have died from the virus.
On March 22, U.S. authorities announced a diagnosis of avian influenza in bovines after some dairy cows at farms in Texas, Kansas, and New Mexico became ill and there were reports of dead wild birds on farm grounds. The inspection has started.
About 10% of the milking cows on the affected farms appear to be sick, most of them elderly. It is unclear whether avian influenza is the cause of all animal illness. U.S. authorities are moving quickly to conduct additional testing.
How did the cow become infected with the virus?
The Department of Agriculture announced that the cows appear to have contracted the virus from infected wild birds. However, it is unclear exactly how the virus was transmitted between species.
Most mammals that contract bird flu are carnivores, such as foxes and seals, who most likely contracted the virus by eating dead or infected birds.Because cows don’t eat birds, it’s difficult to explain the source of infection. Richard Webby at St. Jude Children’s Research Hospital in Tennessee. Feces and saliva from wild birds may have contaminated the cows’ water and feed.
“The biggest question that I don’t fully understand is how do you account for transmission across the state with such geographic spread,” Webby said.
The worst-case scenario is that the virus spreads among cattle, but that’s probably unlikely, he said. This is because there is still no evidence that avian influenza can be transmitted between mammals.
Do sick cows increase the risk of avian influenza spreading to humans?
The risk of contracting bird flu remains low for most people. Initial testing of samples taken from infected cows has found no genetic changes that would suggest the virus is more transmissible to humans.
But each time a mammal gets avian influenza, Webby says, it gives the virus a chance to acquire the mutations it needs to spread between mammals. “But to put this into perspective, we still need some answers. Above all, how many cows are showing evidence of being infected with the virus?” If there are very few, the virus is likely to become a dead end again, as it did in foxes, bears, and other previously infected animals.
Is milk safe to drink?
Yes, milk is still safe to drink. The USDA already requires dairy farms to send only milk from healthy cows for processing. Milk from infected cows is also being discarded and kept out of the food supply.
Even if contaminated milk enters the supply chain, pasteurization kills bacteria and viruses, including influenza.
The fans roar to life, pumping air upwards at 260 kilometers per hour. Wearing a baggy blue jumpsuit, red helmet, and plastic goggles, claudia de rum When you step into the glass room… Whoosh! Suddenly, she was suspended in the air, her wide grin on her face excited by her simulated experience of free fall.
I persuaded de Lamme, a theoretical physicist at Imperial College London, to go indoor skydiving with me at iFLY London. It seemed appropriate, given that much of her life has been dedicated to exploring the limits and true nature of gravity. At least on this occasion, jumping out of the plane wasn't an option for her.
As she explains in her new book, the beauty of falling, de Rum trained to be a pilot and then an astronaut, but medical problems ruined his chance for the ultimate escape from gravity. But as a theorist, she continued to delve deeper into this most familiar and mysterious force, making her mark by asking her fundamental question: “What is the weight of gravity?” Ta.
That means she is a graviton, a hypothetical particle that is thought to carry this force. If it had mass, as de Rum suspects, that would open a new window on gravity. Among other things, we may finally discover a “gravitational rainbow” that betrays the existence of gravitons. Along with gravitons, it will also become possible to provide a quantum description of gravity, which has been sought for many years.
When De Rum is suspended in the air, she makes it look easy. She will ascend soon…
Beer brewers produce a wide variety of flavors from just a handful of ingredients

Artificial intelligence that can predict taste from beer's chemical composition could help create alcohol-free versions that taste exactly like regular beer.
Predicting flavor from a compound is difficult because complex interactions between ingredients and the psychology of taste can result in surprisingly different perceptions, even among people who have tasted the same thing.
To deal with this, kevin verstrapen Professors at the University of Leuven in Belgium have developed an AI model that can predict the flavor profile of beer based on its chemical composition and suggest ways to improve the flavor.
The model was trained on beer reviews by a panel of 16 expert tasters who scored each beer on 50 attributes, as well as 180,000 public ratings from online beer rating websites. The study compared these subjective descriptions with measurements of 226 compounds in 250 Belgian beers.
“Hundreds of these compounds are received by our nose and mouth, but mostly in the nose, and then processed in the brain to give us what we think of as flavor,” Verstrepen says. “The fact that we can actually predict this accurately using machine learning is pretty amazing.”
Verstrepen and his team used this model to predict how to improve the flavor of beer by adding mixtures of specific compounds, such as lactic acid and ethyl acetate. The resulting beer was given significantly higher ratings by a panel of trained tasters.
In another study, which has not yet been published, after making the changes suggested by the model, non-alcoholic beer became indistinguishable from regular beer, Verstrepen said.
The idea is that brewers should aim to implement AI recommendations by tweaking recipes, rather than simply adding flavors, he says. “Simply adding pure aroma compounds is not really acceptable in beer brewing. All you need is malt, hops, water, and yeast.”
“So I look at it as a tool, specifically to be used to make better non-alcoholic beer, but not to take away the art of crafting good beer in an artisanal way,” Versträpen said. To tell.
This artifact is a two-piece construction with a rounded top soldered to the main body.
Six horizontal bands are placed in a zigzag pattern around the body and overlaid on an incised brick or basket weave pattern.
“'' is engraved at the base of the band.I still love you like' Roman capital in serif font.
The researchers said: “Posey's inscription appears on several 17th-century silver thimbles found across England and Wales.”
“The Cardiff, Kent and Hampshire examples were all reported through the Treasure Act 1996.”
“Such romantic passages are very similar to those found on modern posey rings,” they added.
“Perhaps a thimble, worn on one's finger while sewing, was considered an intimate (and therefore romantic) possession, suitable as a gift between lovers.”
Astronomers using the NASA/ESA Hubble Space Telescope have captured detailed images of the globular star cluster NGC 1651 in the constellation Mensa.
This Hubble image shows the globular cluster NGC 1651 about 162,000 light-years away in the constellation Mensa. Image credits: NASA / ESA / Hubble / L. Girardi / F. Niederhofer.
Globular clusters are densely packed spherical clusters of hundreds of thousands or even millions of stars.
They are among the oldest known objects in the universe and are preferentially associated with the oldest components of galaxies.
There are at least 150 such objects in our Milky Way, and several more may be hidden behind the galaxy's thick disk.
NGC1651 is part of the Large Magellanic Cloud, the largest and brightest of the Milky Way's satellite galaxies.
beginning discovered Discovered by British astronomer John Herschel on November 3, 1834, this globular cluster is located approximately 162,000 light-years away in the constellation Mensa.
NGC 1651, also known as ESO 55-30 or LW 12, has a diameter of 120 light years.
“A remarkable feature of this image is that NGC 1651 nearly fills the entire image, even though the globular cluster is only about 10 to 300 light-years in diameter,” Hubble astronomers said. Masu.
“In contrast, there are many Hubble images that feature entire galaxies, tens or even hundreds of millions of light-years in diameter, that more or less fill the entire image.”
Color images of NGC 1651 consist of observations from. Hubble's Wide Field Camera 3 Found in the near-infrared and optical portions of the spectrum.
“A common misconception is that Hubble and other large telescopes can observe objects of vastly different sizes by zooming in, much like we would with special cameras on Earth,” the astronomers said. Ta.
“However, while smaller telescopes may have the option to zoom in and out to some extent, larger telescopes do not.”
“Each telescope instrument has a fixed 'field of view' (the size of the area of the sky that can be observed in a single observation).”
“For example, WFC3's ultraviolet/visible light channel, the channel and instrument used to collect the data used in this image, has a field of view that is approximately one-twelfth the diameter of the moon as seen from Earth. Masu.”
“Every time WFC3 makes an observation, it becomes the size of the region of sky it can observe.”
“There are two reasons why Hubble is able to observe objects with such widely different sizes,” the researchers said.
“First, the distance to an object determines how big that object appears from Earth, so an entire galaxy that is relatively far away is compared to a relatively nearby globular cluster like NGC 1651. could take up the same amount of space as the sky.''
“In fact, a distant spiral galaxy lurks just to the left of the cluster in this image. It's undoubtedly much larger than the cluster, but here it appears small enough to blend in with the foreground stars.”
“Second, multiple images across different parts of the sky can be mosaicked to create a single image of an object too large for Hubble's field of view.”

Warning analysts have highlighted the increasing power and frequency of cyberattacks linked to Chinese intelligence as foreign governments test their response. This comes in the wake of revelations concerning a large-scale hack of British data.
Both the British and American governments disclosed that the hacking group Advanced Persistent Threat 31 (APT 31), supported by Chinese government spy agencies, has been targeting politicians, national security officials, journalists, and businesses for several years. They have been accused of carrying out cyber attacks. In the UK, hackers potentially accessed information held by the Electoral Commission on tens of millions of British voters, and cyber espionage targeted vocal MPs on the threat posed by China. Sanctions have been announced against Chinese companies and individuals involved by both the US and UK governments.
New Zealand’s government also expressed concerns to the Chinese government about Beijing’s involvement in attacks aimed at the country’s parliamentary institutions in 2021.
Analysts informed the Guardian that there are clear indications of a rise in cyberattacks believed to be orchestrated by Chinese attackers with ties to Chinese intelligence and government.
Chong Che, an analyst at Taiwan-based cyber threat analysis firm T5, stated, “Some hacking groups often rely on China to carry out attacks on specific targets, such as the recent iSoon Information incident. It’s an information security company that has a contract with intelligence agencies.” T5 has observed an increase in constantly evolving hacking activity by Chinese groups in the Pacific region and Taiwan over the past three years.
Chong also mentioned that while there isn’t enough information to directly trace activities to China’s highest leadership (with the Chinese government denying the allegations), activity can’t be discounted considering the Chinese system that does not differentiate… They believe that their objective is to infiltrate specific targets and steal critical information and intelligence, whether political, military, or commercial.
Several analysts noted that Western governments have become more willing to attribute cyberattacks to China after years of avoiding confrontation with the world’s second-largest economy.
David Tuffley, senior lecturer in cybersecurity at Australia’s Griffith University, remarked, “We’ve shifted from being less critical in the past to being more proactive, likely due to the increased threat and scale of actual intrusions. They are now a much more significant threat.” Cyberattacks are part of China’s gray zone activities, actions that approach but do not reach the threshold of war.
Tuffley highlighted that while much of the cyber activity is regionally focused on Taiwan and countries in the South China Sea with territorial claims, the cyberattacks are widespread. China aims to cause instability in the target country and test adversary defenses, rather than engage in violent war.
Tuffley warned of the risk of escalation, noting that other governments like the US and UK also possess sophisticated cyber espionage capabilities but have not publicly threatened action against China. US authorities charged individuals with conducting cyberattacks in violation of US law, suggesting a deep level of knowledge about the attacks.
Adam Marais, chief information security officer at Arctic Wolf, commented, “If you’ve been involved in cybersecurity for many years, this report from UK authorities won’t surprise you at all. Beijing continues to view cyber as a natural extension of its national strategy and has little fear of using cyber technology to advance its national interests.”
