A team of geologists from Curtin University discovered clear evidence of a high-speed impact that occurred 3.47 billion years ago (Archean EON) in the heart of the Pilbara region of Western Australia. This discovery makes it the oldest impact crater found on Earth, surpassing the previous record of 2.2 billion years.

“When more than a million craters with diameters exceeding 1 km and over 40 km, more than 100 km, the moon holds an exquisite record of the intense artillery fire that the body of the inner solar system has endured during the first billion years of its history.”
“On Earth, this early impact record appears to reflect the destructive efficiency of erosion and subduction, bringing the primary skin back to the convection mantle.”
“Nevertheless, the oldest part of many cratons, the ancient (4-2.5 billion years ago) nuclei of the continent formed 3.5 billion years ago, must maintain evidence of impact fluxes beyond similar regions of the moon of comparable age.”
“However, the oldest recognized terrestrial impact structure in Yarabuba, Western Australia dates 2.23 billion years ago. Where are Archean Craters?”
Professor Johnson and his co-authors investigated the Archiunlock Formation at the Arctic Dome in the Pilbara region and discovered evidence affecting major metstones 3.5 billion years ago.
“This discovery has challenged our previous assumptions about the ancient history of our planet,” Professor Johnson said.
Researchers discovered Archean Crater thanks to crushed cones. This is a unique rock formation that has only formed under the intense pressure of the Metstone strike.
The crushed cone at the site, about 40 km west of the marble bar, was formed when metstones over 36,000 km/h were pounded into the area.
This was a major planetary event, with craters over 100 km wide sending fragments flying around the world.
“We know that in the early solar systems, seeing the moon is common,” Professor Johnson said.
“To date, the absence of truly ancient craters means they are largely ignored by geologists.
“This study provides an important part of the puzzle of Earth’s impact history and suggests that there may be many other ancient craters that can be discovered over time.”
“The discovery shed new light on the way metstones formed the early environment of the Earth,” said Chris Kirkland, a professor at Curtin University.
“Discovering this impact and finding more from the same period can explain a lot about how life began, as impact craters created an environment that is friendly to microbial life, such as heated pools.”
“It also fundamentally refines our understanding of the formation of the earth’s crust. The enormous amount of energy from this impact may have played a role in shaping the early Earth’s crust by pushing part of the Earth’s crust underneath another or rising from deeper into the Earth’s mantle towards the surface.
“It may have contributed to the formation of the craton, the large, stable land that formed the foundation of the continent.”
Discoveries are reported in a paper In the journal Natural Communication.

According to a new study by planetary researchers at Tokyo Planet University, atmospheric gravity waves play an important role in driving airflows, particularly at altitudes, at latitudes.
This image from the Emirates Mars Mission shows Mars and its thin atmosphere. Image credit: UAESA/MBRSC/HOPE MARS MISSION/EXI/ANDREALUCK.
“On Earth, the large atmospheric waves caused by the rotation of a planet known as the Rossby waves are the main effect on the way stratospheric air circulates, or the lower part of the medium atmosphere.”
“However, our research shows that on Mars, gravitational waves have the dominant effect in the mid-atmosphere and at high latitudes.”
“Rossby's waves are large atmospheric or resolved waves, while gravitational waves are unresolved waves, meaning that they must be estimated using finer, more indirect means to be measured or modeled.”
“Don't confuse it with gravitational waves from the body of a large star. Gravitational waves are atmospheric phenomena when packets of air rise and fall due to buoyancy fluctuations. Their oscillating movements cause gravitational waves.”
Due to their small-scale nature and limitations of observational data, planetary researchers previously discovered that it is difficult to quantify their importance in the Martian atmosphere.
Therefore, Professor Sato and her colleagues turned to the Ensemble Mars Atmosphere Reanalysis System (EMARS) dataset generated by various space-based observations over the years to analyze seasonal variation.
“We found something interesting. Gravitational waves promote the rapid vertical movement of angular momentum, which has a major impact on the meridian or north-north in the mid-atmospheric circulation on Mars,” said Anzu Asumi, a graduate student at Tokyo University.
“It's interesting because it's more like the behavior seen in the Earth's mesosphere, not in our stratosphere.”
“This suggests that the effects of these waves may need to be better incorporated to improve existing Mars atmospheric circulation models, and could improve future climate and weather simulations.”
The team is currently planning to investigate the effects of Mars sandstorms on atmospheric circulation.
“So far, our analysis has focused on a year without large sandstorms,” Professor Sato said.
“However, I think these storms could dramatically change the state of the atmosphere and strengthen the role of gravitational waves in circulation.”
“In our research, there is a basis for predicting Mars weather, which is essential to guarantee the success of future Mars missions.”

The mass of the ultra-large black hole in the heart of the large Magellan cloud, a small milky satellite galaxy, is approximately 600,000 solar mass.
Impressions of the Hyper Belt Lattist artist ejected from the large Magellan cloud (shown on the right). If the binary star system gets too close to an ultra-large number of black holes, intense gravity will tear the pair apart. One star is captured in tight orbits around a black hole, while the other is thrown outward at extreme speeds – often exceeding thousands of kilometers per second, making it a high-speed star. The inset diagram illustrates this process. The orbital path of the original binary is displayed as an interwoven line, one star is captured by a black hole (near the center of the inset), and the other is ejected into space (bottom right). Image credit: CFA/Melissa Weiss.
“Our Milky Way galaxy halo includes a few stars running faster than local escape speeds in orbit that carry them into intergalactic space,” said Dr. Jesse Han, Ph.D. of the Harvard & Smithsonian Center for Astrophysics and Colleagues.
“One mechanism for generating such ultrafast stars is the Hills mechanism. When a close binary star wanders near an ultrahigh Massive black hole, one star can be captured, while the other is ejected at a rate that reaches more than a second.”
In their new study, astronomers followed the path with ultrafine accuracy of 21 superfast stars in halos outside the Milky Way.
They confidently categorized these stars, finding that seven of them coincided with those born out of the center of the Milky Way.
However, the other nine stars coincided with those born from the centre of the large Magellan cloud, about 160,000 light years away from us.
“Cosmologically speaking, it's amazing to notice another super-large black hole just below the block,” Dr. Han said.
“Black holes are so stealthy that this has been under our noses this time.”
Researchers discovered a large Magellanic Cloud black hole using data from ESA's Gaia Mission.
They also used improved understanding of the orbital of the d-star galaxies around the Milky Way, which was recently obtained by other astronomers.
“We knew these superfast stars had been around for a while, but Gaia provided us with the data we needed to figure out where they actually came from,” says Dr. Kareem El-Badry, an astronomer at Caltech.
“Combining these data with a new theoretical model of how these stars move, we made this incredible discovery.”
“The only explanation we can come up with for these data is the presence of a monster black hole in the next Galaxy,” said Dr. Scott Lucchini, an astronomer at the Harvard & Smithsonian Center for Astrophysics.
The intuitive machine Athena Lander has reached the moon, but appears to have fallen. The Lander is still working, but it is not yet clear which part of the mission will still be able to achieve.
The spacecraft was mounted on a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center (KSC) in Cape Canaveral, Florida on February 27th. It landed on March 6th, but the landing was not completely successful, and the exact location or orientation of the lunar surface is still unknown.
“I don’t think we’re in the right attitude on the surface of the moon,” the CEO of the intuitive machine said. Stephen Altmus At a press conference just after landing. This is similar to the company’s last attempt at landing on the moon, the Odysseus spacecraft. It was the first time a private company had landed a spacecraft on the moon, but it turned over to its side and was unable to send much of the data back.
There are a variety of scientific instruments in Athena, but perhaps the most important of these are the regoliths and ice drills to explore new terrain (Trident), a NASA experiment designed to drill up to a maximum metre to a meter through the lunar soil. The purpose is to take samples from underground, analyze their contents, and search for water ice and other compounds.
“This experiment marks an important milestone as it will mark the first robotic drilling activity to be carried out in the Antarctic region of the lunar.” Jacqueline Quinn At KSC at a press conference on February 25th. If Trident is still working, “This is an important step in understanding and leveraging the moon’s resources to support future exploration,” she said.
As part of the IM-2 mission, Athena carried several rovers to the moon. One of them is called Grace after Grace Hopper, a computer scientist and mathematician, and unlike the rover that came before him, he is designed to fly around the surface, firing small boosters to dive into the air up to 100 meters, travelling about 200 meters. Grace aims to explore the strange, permanently shadowed craters of the moon.
Athena operators were able to send craft commands to turn it on and off and downlink some of their data to Earth. The solar panels also function to charge Lander electronics. That seems good news, but the team is still working to figure out which instruments can achieve some of their scientific goals, Altemus said.
This is part of a broader push to increase lunar exploration in preparation for planned human missions over the next decade. The Blue Ghost Lander at Firefly Aerospace arrived in the moon on March 2nd. Resilience Lander, a Japanese company Ispace, is on the way.
Following a failed test flight in January, SpaceX set out for another launch attempt on Thursday hoping for a better outcome.
Unfortunately, the mission was cut short once again after losing contact with the upper-stage vehicle.
The Starship system, towering at 400 feet, launched from SpaceX’s Starbase site near Brownsville, Texas, for its eighth test flight at 6:30pm.
However, within eight minutes, similar to the January incident, some engines seemed to shut off. Live video footage showed the craft spinning before all communication was lost.
In the live webcast, SpaceX Communications manager Dan Huot announced, “I think it’s clear that we won’t continue with today’s mission.”
Shortly after the mishap, Florida airports issued ground stops due to the “space launch incident” in Fort Lauderdale Hollywood International Airport, Orlando International Airport, and Miami International Airport.
Videos circulating online show explosions and potential debris in parts of Florida. One video posted by an X user shows what appears to be an overhead fireball in Boynton Beach, Florida.
SpaceX stated on X that the Starship suffered a collapse, described as a “rapid, unplanned demolition.”
The company is now analyzing data from the flight tests to determine the root cause of the incident.
Huot mentioned in the webcast that SpaceX will be monitoring potential debris and working closely with air traffic restrictions.
While accidents are not uncommon in the development of new rockets and spacecraft, this marks the second consecutive setback for SpaceX.
During the seventh test mission in January, a similar loss of communication occurred, eventually leading to an explosion over the Caribbean.

Following the incident, the Federal Aviation Administration launched an investigation. Despite clearing the spacecraft for Thursday’s test flight, investigations are ongoing.
The FAA, among other agencies, has faced budget and staffing cuts under the Trump administration, raising concerns about oversight in areas like commercial spaceflight.
SpaceX’s internal investigation revealed that a leaky propellant likely caused the explosion during the previous test flight.
SpaceX made upgrades to prevent similar incidents and enhance safety measures before the Thursday launch.
Despite the short-lived test flight, SpaceX achieved a significant milestone with the Super Heavy Booster returning successfully to the launch site and landing on the Tower’s robotic arm.
This marks the third successful “Catch” operation by SpaceX, a crucial step towards the goal of creating a fully reusable Starship system.
Starship, the most powerful rocket in development, consists of a first-stage booster and an upper-stage spaceship called Super Heavy.
SpaceX officials emphasize that many more test missions will likely be conducted before the Starship can transport humans.
The next-generation Megarocket, Starship, is expected to play a pivotal role in NASA’s moon missions and potentially future missions to Mars.
Feedback is the latest science and technology news of new scientists, the sidelines of the latest science and technology news. You can email Feedback@newscientist.com to send items you believe readers can be fascinated by feedback.
Delicate topics
Feedback reads many academic articles, but we often suffer from their titles, which is not despicable and clearly unclear. What’s even worse is that it is the preface to the academy, which is said to be said to be a reference to humorous pop culture.
However, sometimes you come across research with a lively title and key points. We love the 2000 structural biology paper.”Ribosomes are ribozymes“This is an absolute model of efficiency (suppose you know the meaning of two nouns), and there is a February paper on Biorxiv. New Scientist Contributor Chris Sims, titled “The rough mental map of the breast is fixed to the nipple“.
It may probably require a bit of context. Parts of the human body are more sensitive to touch than other parts of the body. The face, especially the lips – and the tips of the fingers are very sensitive, but our backs are much less.
This is one of the classic experiments you can do at home. Get chopsticks and other dull tools and happily thrusts your partner gently. Whether you’re poking them with your lips or fingertips, or even just millimeters, you’ll know if you’re moving the continuous pork location. But if you thrust them back, they’ll be awful to decide if you’ve moved it or not. This is because the back has less touch sensitive nerves there.
The authors of this new preprint discovered a gap in the literature. “Tactile vision has been extensively studied in the limbs and face, while the torso vision has attracted much less experimental attention. The breasts are largely ignored,” they write.
Do not drag the suspense. The breasts have very low tactile vision, which can be seen as even worse than the back. Apparently, “Touch had to be 3-4 times further away from the chest than the hand to get comparable position identification performance.”
Feedback is not sure what this is at all Caroline Cleared Perez I had it in mind when she wrote it Invisible womandocumenting the myriad ways in which women have been excluded from scientific research. However, as part of the basic information, it appears to have its purpose.
The main point of feedback is that you want to be a wall fly due to the recruitment process. “What do you want to do with me?”
Even longer words
In early November 2024, I paddled the column with a long, increasingly long torrent of words as I had a bit of lack of feedback due to a short break (for a long time) of Global Idiosai.
Apart from that, we did it wrong. Francis Wenban Smith wrote to point out our mistakes: “You were two letters short in an attempt to pad out your column with ‘Flocsinocinosis’. The correct word is “Floccinaucinihi Lipilification.” “
If you can’t see the difference between the blizzards of these two letters – and we will not blame you. I couldn’t clearly do that, so the second has an extra “li” just before “piri”. Feedback would like to assure readers that they have been given harsh stories.
In the process of verifying that I actually misspelled Floccinaucinaucinihi Lipilification, the feedback entered two versions into popular search engines. The correct version brought up dictionary entries as highlighted responses. The wrong version brought up our article (embarrassing). Above that was an AI summary of the fake words. This is the opening line:
“Flocsinisia is a long term meaning to view something as unworthy or trivial. It was the longest word in the Oxford English Dictionary until 1982. Flocsinisia is a 29-letter word with 12 syllables. It contains nine me, but no e.”
Unlike AI, readers who can count to 29 will notice everything that claims that the number of letters and syllables is wrong. Feedback is proud to contribute to the continuous pollution of our information ecosystems in our own small ways.
Unsafe date
Like many others in life, dating is becoming a micro-target. You can also use huge apps like Tinder, but there is also an increasing number of dating sites that have never been seen before.
Perhaps all niches are aimed at people who have not been vaccinated against Covid-19. Or, more precisely, “We don’t support any kind of vaccination, but the raw treatment is specifically tailored to non-vaccination or mRNA-based injections for Covid-19.”
Feedback has many questions about uninjected, the most pressing of which is how does the company decide who can participate? Perhaps this is so basic, so there’s no need to say it, but it can’t prove to be negativity.
After scrutinizing the site’s FAQ, we found the answer. [sic] We have a foundation of trust and we operate in an honorary system. However, we recommend “Raw Verified” upgrades for those who want the most security and security when selecting a future partner.

The rapid expansion is a result of inflammation, which serves a protective purpose.
Dr. Robert Schmerling, a rheumatologist and faculty member at Harvard Medical School, explained that inflammation is the body’s natural response to injury or illness in an attempt to promote healing. More info on Inflammation.
Inflammation can be detrimental as it is linked to various chronic conditions like diabetes, heart disease, and allergies. Experts believe that reducing chronic inflammation is crucial for healthy aging.
Dr. David Haffler, a neurologist and professor of immunobiology at Yale University School of Medicine, described inflammation as a necessary defense mechanism that helps the body fight infections.
Inflammation has been recognized for centuries, with ancient Roman writer Aurus Cornelius Cercus outlining its core characteristics. This process involves fluid, proteins, and white blood cells traveling to the site of injury, resulting in redness, swelling, heat, and pain to aid in recovery.
While acute inflammation is beneficial in the short term, chronic inflammation can have long-lasting negative effects on the body.
Causes of Chronic Inflammation
Factors like obesity, smoking, and dietary choices can contribute to chronic inflammation.
Dr. Thaddeus Stappenbeck, chair of inflammation and immunity at Cleveland Clinic, believes that the modern American diet is a major driver of chronic inflammation.
Consuming processed foods, trans fats, and sugary treats can increase inflammation levels in the body. Although trans fats have been banned by the FDA, a shift towards a plant-based diet rich in fruits and vegetables can reduce inflammation.
“Sedentary lifestyle, poor sleep, and stress can also contribute to inflammation,” mentioned Schmerling.
Symptoms of Inflammation
Common signs include joint pain, fatigue, constipation, depression, and weight loss. Schmerling recommends regular exercise and a plant-based diet to lower inflammation levels.
Research indicates that following a Mediterranean-style diet can reduce inflammation markers in the body.
“Lifestyle changes can positively impact inflammation levels,” Schmerling added.
Impact of Chronic Inflammation on the Heart
According to the CDC, around 129 million Americans suffer from chronic illnesses, with the prevalence increasing every five years.
Experts suggest that chronic inflammation plays a significant role in the development of these conditions.
Prolonged inflammation can lead to heart disease, plaque buildup in blood vessels, and even neurodegenerative disorders.
Autoimmune diseases like lupus and multiple sclerosis are also associated with chronic inflammation.
Inflammation is a common feature in various diseases, highlighting the importance of addressing it early on.
Testing for Chronic Inflammation
Blood tests like erythrocyte sedimentation rate and C-reactive protein measure inflammation levels in the body. However, these tests may not always provide clear results.
False positives are possible, so symptoms should be considered alongside test results.
While some advocate for routine inflammation tests, experts like Schmerling and Stappenbeck advise against it for healthy individuals without symptoms.
There are more sensitive tests like HS-CRP that can detect small increases in inflammation levels, but their widespread use is still debated.
Monitoring inflammation levels can help identify individuals at risk of heart disease or stroke in a timely manner.
Washington – Early Man utilized animal bones to create cutting tools 1.5 million years ago on a regular basis.
A recent discovery of 27 sculptures and sharp bones from elephants and hippos in Tanzania’s All-Bai Valley site has extended the timeline for the use of ancient bones by around a million years. Researchers already knew that early individuals crafted simple tools from stones as long ago as 3.3 million years.
New discoveries of ancient humans published in Nature on Wednesday have shown that they had a more sophisticated toolkit, incorporating various materials, according to William Harcourt Smith, a paleontologist at the American Museum of Natural History. He was not involved in the study.
A well-preserved bone tool measuring up to 16 inches (40 cm) may have been created by fracturing the bulky ends of leg bones and chipping off the flakes from the remaining bone shaft using stones. Research co-author Ignacio de la Torre, a researcher at the Spanish National Research Council, explained that this technique was used to produce one sharp edge and one tip.
The bone tools were likely used as hand axes, handheld blades not attached to a handle, for the purpose of butchering animal carcasses.
These blades were ideal for removing flesh from elephant and hippo carcasses but were not utilized as spears or projectiles. “I don’t believe they were hunting these animals. They were likely scavenging,” he stated.
Numerous artifacts exhibit signs of being struck in order to remove more than dozens of flakes, indicating a sustained level of craftsmanship.
The consistent choice of bones – specifically large, heavy leg bones from a particular animal – and a pattern of uniform modifications suggest that early humans deliberately selected and crafted these bones, as noted by paleobiologist Milia Pacheco from the Federal University of San Carlos in Brazil, who was not part of the study.
The bones show minimal signs of erosion, trampling, or gnawing by other animals, ruling out the possibility of natural factors shaping the tools.
These bone tools date back over a million years, predating the emergence of our species, Homo Sapiens, by approximately 300,000 years.
According to Brianna Poviner, a paleontologist with the Smithsonian Human Origins program, when the tools were created, three types of human ancestors coexisted in the same East African region.
This tool could have been created and used by Homo Erectus, Homo Habilis, or Paranthropus Boisei. “It could have been any of these three, but it’s nearly impossible to determine which one,” Poviner mentioned.
In less than a week, the second privately constructed US spacecraft is poised to land on the moon.
The robot lander, named Athena, was created by an intuitive machine based in Texas. It was launched into space on February 26th and has been traveling to the moon for the past week.
About the size of a dishwasher, the six-legged ship is set to land in the lunar Antarctic area, with plans to spend a week searching for possible water ice beneath the lunar surface.
The landing is scheduled for Thursday at 12:32 pm ET.
If successful, Athena will be the second vehicle to land on the moon in five days, following another robotic lander built by Texas-based Firefly Aerospace, which landed there on Sunday.
Both missions are part of NASA’s Commercial Moon Payload Services program, aimed at assisting private companies in developing Moonlander technology. Over a dozen US companies are involved in this initiative, which is crucial to NASA’s overarching goal of returning astronauts to the moon.
Athena’s landing will mark the second moonshot for the intuitive machine. The company previously made history in February 2024 by landing a commercially built spacecraft on the moon, becoming the first American spacecraft to land there in over 50 years since the 1972 Apollo 17 mission.
Athena’s Moon Lander. An intuitive machine
The Lander, known as Odysseus, experienced a successful landing despite tipping over afterwards.
Both intuitive machine missions are focused on the Antarctic region of the moon. Odysseus landed near a crater called Marapart A, while Athena is targeting a vast flat mountain plateau known as Mons Mouton.
Scientists believe that water ice is relatively abundant in the moon’s Antarctic region, making it a crucial resource for potential crew missions and long-term stays on the moon.
Athena is equipped with several rovers, including the suitcase-sized vehicles developed by Colorado-based Lunar Outpost called Mapp (Mobile Autonomous Research Exploration Platform). These rovers are designed to explore the landing site and capture 3D images of the terrain.
Furthermore, a thumb-sized rover named “Astroant,” created by researchers at the Massachusetts Institute of Technology, will assess the health of the map rover and take regular temperature measurements.
In addition, the mission includes releasing a drone named Grace, which will hop around the Athena landing site, covering approximately 650 feet in four hops to explore nearby craters and scan for hydrogen traces and ice deposits.
While on the moon, Athena will also test a 4G communications system developed by Nokia, which could facilitate communication and data transfer between spacecraft on the moon.
Moon exploration continues beyond this week, with a Lander and small rover from a Japanese company called Ispace set to land near the northern pole’s vast basin known as Male Frigolis.
According to satellite measurements from the European Union’s Climate Service Copernicus, there is less sea ice covering the ocean this February.
“One of the consequences of a warm world is to melt sea ice, and both Poles’ records or near-recorded low-sea ice covers have pushed the world’s sea ice cover to the lowest ever.” Samantha Burgess The European Middle Distance Centre is forecast in a statement. According to the service, global temperatures in February this year rose 1.59°C above the pre-industrial average, making it the third security in March on record.
These high temperatures have affected the global sea ice range, including both the Arctic and Antarctic, which is currently close to the largest in the year. Satellite records from both regions date back to 1979.
In the Arctic, sea ice was 8% below average throughout February, missing an area of nearly the size of the UK ice. This was the three consecutive months of successive months that set a low monthly new record in the Arctic.
This decline in the Northern Hemisphere is combined with the long-term decline in Antarctic sea ice seen over the past two years. Antarctic ice appeared to recover to near average levels last December, but then again fell rapidly. In February, the ice reached the fourth-lowest range on record for the month, 26% below the average.
Record low ice in both hemispheres is a “cause of serious concern,” he said. Robert Larter In a statement in the UK Antarctic Survey. He says that ice shortages could harm the polar ecosystems, expose ice shelves to more seawater, and accelerate melting and rising sea levels.
The lack of ice also affects beyond the poles. Less ice means less solar radiation is reflected in the universe, increasing warming. It can also weaken global ocean currents, relying on the dense salt water that is generated when sea ice forms.
The Blue Ghost took a photo of the shadows on the moon.
Firefly Air Space
The Texas company has achieved its second commercial landing on the moon. And the first company didn't fall with a touchdown. Success comes even in the gusts of private and state moon exploration.
The Firefly Aerospace's Blue Ghost Lander was launched on January 15th on top of the SpaceX rocket, and spent 45 days of travel to the moon. It landed at 8:34am on March 2nd. Chrysium in the Maresa smooth basin formed by a volcanic eruption three billion years ago.
Using thrusters, Blue Ghost slowed from an orbital speed of 1.7 km/sec to just 1 meter/sec, then landed on shock absorbing legs within 100 meters of the target. Jason Kim, CEO of Hotaru; I told CNN That the short height of the craft was the key to a safe landing: “It is a successful design, you see past designs and successful past designs, [they] Very similar – short and squatti. ”
The Blue Ghost is approximately 2 metres tall and 3.5 metres wide, and features 10 scientific instruments as part of NASA's Commercial Lunar Payload Services Program, which uses the private sector to perform various experiments prior to the planned crew mission.
These include testing of the lunar planet, which uses compressed gas blasts to mix and collect samples of lunar dust, radiation-curable computer chips, and lunar GNSS receiver experiments that pick up signals from GPS and Galileo navigation satellite constellation to bring Earth into orbit to provide timing data for the moon.
The Lander will be operating on Earth Day-Moon Day, approximately 14 days before falling into the darkness and closing around March 16th. While other landers have unexpectedly survived the harsh conditions before, a frostling moon night will likely be the end of the mission.
Last February, the Texas-based intuitive machine landed the Odysseus spacecraft on the moon, becoming the first private company to achieve a feat previously only achieved by the National Space Agency. Odysseus fell to the side while landing, but still managed to work surprisingly well.
Many moon missions are in progress or planning. Also, Blue Ghost's Launch Rocket was another commercial moon mission, Ispace's Resilience Lander, intended to land in April. It is expected that around 12 landers will reach the moon in 2025 alone.
Light micrographs of neck smears or Pap smears from people with bacterial vaginosis

Women with bacterial vaginosis, a recurrent condition that increases the risk of pregnancy complications, can benefit from male sexual partners being treated with antibiotics, according to a trial that found that their risk of symptoms returning was nearly half.
“Treating male partners has led to the most important invasions to improve the rate of recurrence in women that we have seen for decades,” he says. Catriona Bradshaw He led the work at Monash University in Melbourne, Australia.
Bacterial vaginosis (BV) affects Approximately one-quarter of women of reproductive age all over the world. It occurs when “harmful” bacteria grow in excess in the vagina and cause vaginal discharge. Turn the greyish white and smell the fishthere are potentially serious complications. “It increases the risk for women to acquire a wide range of sexually transmitted diseases, such as HIV, and complications during pregnancy, such as preterm birth and miscarriage,” says Bradshaw.
Doctors usually treat the condition with antibiotics in the form of creams that can be applied inside the vagina, but symptoms often recur because having a sex appears to reintroduce the problematic bacteria, Bradshaw says. “One in two people will regain their BV within three to six months of the recommended treatment regimen,” Bradshaw said.
To address this, Bradshaw and her colleagues recruited 137 monogamous women in Australia with bacterial vaginosis along with their male partners. All women took standard antibiotics for a week, but about half of their partners were given oral antibiotics and were told to apply antibiotic cream to their penis during the same period. The remaining men were not treated. None of the participants were transgender.
Three months later, 63% of women whose partners were not treated had recurrence symptoms, while only 35% of women who received antibiotics experienced a recurrence. “This definitely has a significant effect of becoming a valuable intervention for this group of women,” he says. Janneke van de Wijgert At Utrecht University in the Netherlands.
“I've seen a lot of women who have issues with BV ongoing. I'll definitely apply this new information to my clinical practice.” Christina Muzny University of Alabama at the University of Birmingham.
The team did not track all participants over the long term, but they regained contact after years and said they had no symptoms. “Last week I spoke to someone who had been exempt from BV for two years since they joined. These women had been recurring very much before the trial.” Lenka Vodstrcil At Monash University.
However, this approach does not work for women with casual sexual partners. There, it may be difficult to get people to adhere to taking antibiotics, says Van de Wijgert. Even in monogamous relationships, she says, men may not always be willing to take antibiotics. “We've seen this with condom use. This also reduces BV recurrence. It can be really difficult for women to have their male partners use condoms.”
Early trials of the norovirus vaccine pill are committed to protecting against the infamous “winter vomiting” bug, and researchers say it could be used in a few years.
The virus is highly contagious and infects and causes the stomach and intestines Vomiting and diarrhea. Most people recover within a few days, but very young people and older people, especially going to the hospital, costing a considerable amount of medical care. “In the US alone, it’s 10 billion.[dollar]- A problem of one year.” Shawn Tucker At Biotech Company Vaxart in San Francisco, California.
This has spurred scientists to develop vaccines, but so far, efforts have failed. This is because previous attempts focused on developing injectable vaccines. This isn’t very good for producing protective antibodies in the intestines where the virus replicates. Tucker says.
To deal with this, Tucker and his colleagues Previously developed oral norovirus vaccines This will supply proteins to the intestines from the Gi.1 norovirus mutant. The first trials in adults under the age of 50 found that tablets can produce norovirus-specific antibodies in the intestines, but it is probably not a vaccine priority given that people in this age group generally recover easily from the virus.
Researchers are currently testing vaccines in people in the US between the ages of 55 and 80. The team gave 11 people the pills, while the other 22 took the placebo. About a month later, the researchers collected blood and saliva samples from the participants.
They found that people who took the vaccine had higher levels of IgA antibodies. These antibodies were increased by more than 10 times in the blood and about 7 times in saliva compared to samples just before vaccination. In contrast, the placebo group showed little change in antibody levels.
Importantly, antibodies are still present in people who took the pills, albeit at lower levels after 6 months, suggesting that they can provide permanent immunity. “The fact that they have this robust antibody response makes me hope that it can provide protection. [against infection]”I say Sarah Cady At Cornell University in New York. “In particular, the salivary antibody response is a way to get a snapshot of what’s going on in the intestines because of similar immune responses,” she says.
However, further research should investigate whether the vaccine actually prevents infection or reduces spread spread of norovirus, she says. The team wants to explore this.
Furthermore, this study focused only on one norovirus variant. “In the real world, there are a number of different strains you may encounter. The vaccine may not protect all of them,” says Caddy. In an unpublished study, researchers found that versions of vaccines containing both Gi.1 and Gii.4 norovirus variants (the latter currently surges in the UK) produce antibodies against multiple variations.
This suggests we may soon have norovirus vaccines, Tucker says. “If there’s no funding hiccups, if everything goes smoothly, the vaccine could be available in a few years,” he says.
Light has become a strange material called Super Lido

For the first time, strange solids that can flow like liquids were created from light. Studying it will help researchers to better understand the exotic quantum state of matter.
“We actually made light on a solid. It's pretty amazing.” dimitris trypogeorgos At the National Research Council of Italy (CNR). He points out Daniele SanvittCNR also showed how light becomes a fluid over a decade ago. Now, Trypogeorgos, Sanvitto and colleagues use light to create quantum “superlides” that are not just robust.
Supercrissilicon has a simultaneously zero viscosity and has a crystalline-like structure similar to the arrangement of atoms in salt crystals. None of these strange materials correspond to outside the quantum domain. For this reason, they were previously only created in experiments with atoms cooled to very low temperatures.
However, in this experiment, the researchers replaced the supercold atoms with superconducting aluminum gallium arcenide and lasers.
They illuminated the laser on small sections of the semiconductor with narrow ridge patterns. The complex interaction between light and material ultimately formed a type of hybrid particle called polaritons. The ridge pattern constrained how these “quasiparticles” could move, and what energy could the polytons have in such a way as to form a superlide.
Sanvitto says the team had to measure the sufficient properties of this trapped and converted light very accurately and prove it was a solid and fluid with no viscosity. This was a challenge, he says, as scientists have never previously created and evaluated superspores made from light experimentally before.
The new experiments say it contribute to a general understanding of how quantum matter can change states by undergoing topological transitions. Alberto Bramati At the Sorbonne University in France. The team clearly demonstrated that they made a superlido, but he says more measurements need to be made to understand its properties.
According to Trypogeorgos, light-based superlides may be easier to manipulate than those previously created with atoms.
“We're really at the beginning of something new,” he says.
There is Estimated genetic differences of 1.5 million Between wool mammoth and an Asian elephant. Colossal Biosciences, a company that seeks to revive extinct species through genetic engineering, now makes mice with “mammoth-like” fur, each with up to five genetic changes. It seems there's still a way to go.
Certainly, these mice have long, curly hair and blonde hair. In that way, it resembles a wool mammoth coat stored in permafrost. However, it is not clear that bringing the same genetic alterations in Asian elephants with far fewer hairs per area of the skin will result in similar results.
“The work done with these mice doesn't mean there's a solution ready to regain the huge phenotype,” says team members. I love Darren At Stockholm University in Sweden, on the Scientific Advisory Committee of Corosal. “As you point out, we also need to understand how to grow more fur.”
Creating an Asian elephant with these genetic changes would also be much more difficult than doing it in a mouse. “Engineering mutations in mice are an established process and are not particularly challenging.” Dusko Ilic King's College London.
Mouse that has been fixed and unfixed
Huge
Techniques that work in mice often fail in other species, and the size of elephants and their slow breeding significantly increases the time and cost involved. “These methods have not been developed for elephants. They are not easy based on anatomy.” Vincent Lynch At Buffalo University, New York. “That's probably the biggest challenge.”
However, Lynch is undoubtedly achievable. surely, Thomas Hildebrandt At the Leibniz Institute for Zoo and Wildlife Research in Berlin, Germany – Another giant advisor – New Scientist His team is the first time they've collected eggs from elephants, but the results have not yet been made public. Egg collection is an important step in IVF and is a genetic modification of mammals.
So how did Colossal make a “mammoth” mouse? Researchers began by looking for known mutations in mice that looked like fur. “[T]The majority of these genes were selected based on previous observations of the coat phenotype in mice,” read in a paper published today, which has not been peer-reviewed.
They identified eight genes that affect patterns (curse), color and hair length when disabled in mice. According to Colossal, one of these eight is a mammoth and is naturally disabled.
From the mammoth genome, the team identified small mutations that are thought to affect hair patterns, along with another disordered gene involved in fat metabolism.
The company then tried to modify these genes in mice. For example, one experiment used CRISPR gene editing to attempt to disable five of these genes in fertilized eggs. From 134 edited eggs, 11 puppies were born, and one of these puppies invalidated copies of both five genes.
Fur stored in frozen mammoth rank

In another study, the researchers used a form of CRISPR called base editing to abolish several genes in embryonic mouse stem cells. They combined this with another technique called homologous recombination to create the exact mutations found in the mammoth genome. Make accurate changes is much more difficult than disabling genes, but the recombination method works well only in the mouse.
The team then sequenced the cells to identify cells with the desired change and injected into mouse embryos to create chimeric mice. Of the 90 injected embryos, seven mice were born with four intended changes.
These experiments can be said to be successful in producing several mice with desirable physical changes in the fur, but only one genetic change is in exact agreement with what is found in the mammoth genome. It takes more work to achieve Colossal's stated purpose With the creation of “a cold-resistant elephant with all the core biological properties of wool mammoths,” and the elephant pregnancy lasting for about two years, Colossal is in time for a spontaneous 2028 deadline.
“Elephants with fur are not mammoths in the way we think of them.” Juan Antonio Rodriguez At the University of Copenhagen, Denmark. He says many of the 1.5 million differences between the mammoth and the Asian elephant genome may not be effective, but it is not clear which is more important.
Even if we did, it's dangerous to make broader changes, says Rodriguez. “The more things change in organisms, the more likely they are to tinker with major metabolic pathways and genes.”
Imagine looking over a beautiful view. The sun peers closely at the snowy peaks of the mountains in the distance, passing through gentle hills with rivers. There is something wonderful about looking at the outlines of a majestic landscape.
It may not be obvious when you see the night sky, but the universe has its own landscape – the galaxy filaments are separated by empty spaces. We've known this for a long time. But now, a group of cosmologists are taking things further, suggesting that the universe has not only landscapes but also timescapes. The idea is that time flows differently depending on where it is.
To say this is against grain is an understatement. We have always thought that at a large scale, time runs at the same speed across the universe. However, in this photo, known as Timescape Cosmology, there is a large patch of the universe that is ticking over billions of years, for billions of years more than we normally imagine.
It may sound strange, but it is the simple elegance of this idea that seduces physicists. Funny physics has nothing to do with it. It arises naturally from established theories. “It's part of the structure of the general theory of relativity,” the inventor says David Wiltshire At the University of Canterbury, New Zealand. “It's not just a part…
Radcliffe’s wave visualization, a series of dust and gas clouds (marked here) throughout the Milky Way. Approximately 400 light years from the sun, marked yellow
Alyssa A. Goodman/Harvard University
Our solar system passed through vast waves of gas and dust about 14 million years ago, darkening the views of the Earth’s night sky. The waves may have left a trace on our planet’s geological records.
Astronomers previously discovered large ocean-like waves of milky stars, gas and dust that ripple up and down for millions of years. One of these closest and most studied is the Radcliffe waves, about 9,000 light years wide and only 400 light years from the solar system.
Now, Efrem Maconi The University of Vienna and his colleagues discovered that the waves of Radcliffe once were far closer to us, surpassing the solar system 11 to 18 million years ago.
Maconi and his team used data from Gaia Space Telescope, which tracked billions of stars in the Milky Way, to identify recently formed groups of stars within the Radcliffe Wave, and identify the dust and gas clouds that formed from them.
Using these stars, they tracked the cloud orbits in time to reveal historic locations to show how the entire wave was moving. They also calculated the past paths of the solar system, rewind the clock for 30 million years, and discovered that the waves and our sun were approaching intimately about 15-12 million years ago. It is difficult to accurately estimate when the intersection began and ended, but the team believes the solar system is within the wave range around 14 million years ago.
This would have made Earth’s galactic environment as dark as it is today, as we currently live in a relatively empty space realm. “If we are in a dense region of interstellar media, that means that the light coming from the stars will dim,” says Macconi. “It’s like being on a foggy day.”
The encounter may have left evidence in Earth’s geological records and deposited radioactive isotopes on the crust, but considering how long ago it happened, this would be difficult to measure, he says. It says it is useful to find such a galactic encounter, as explaining the geological record of the Earth is a continuous problem. Ralph Schoenrich University College London.
More speculatively, the crossing appears to have occurred during a period of cooling, known as the mid-Miocene. Maconi said the two could be linked, but this would be difficult to prove. Schoenrich thinks that is unlikely. “The rule of thumb is that geology outweighs the influence of the universe,” he says. “When you move around the continent or disrupt ocean currents, you need more because climate change is occurring.”
Under tech billionaire Elon Musk, the Doge Task Force cuts jobs across the US government

The independent task force, US Government Efficiency (DOGE), has closed 18F, a group of in-house technical experts focused on improving the efficiency of the US government. The 18th floor consulted with other government agencies about adopting cost-effective technology and built digital services for tasks such as applying for a passport or submitting online taxes.
Initiatives such as the 18F, another government unit of high-tech consultants, and the US Digital Services (USDS), are “a wealth of professional networks, fixers and dreamers who can modernize government services.” Daniel Castro at Information Technology and Innovation Foundation, a Washington, DC-based think tank.
He says the recent rapid elimination of the 18th floor could halt US government projects. He then expressed his skepticism that Doge is the right organisation to replace USDS or 18F to help the US government use the technology efficiently. “I didn't hire a demolition crew to build a skyscraper,” says Castro.
The US government typically spends over $100 billion on IT services each year, but these expensive technology investments don't often work as they are actually promised. According to to the US Government Accountability Office. 18F said it helped to avoid such waste by consulting with federal and state agencies adopting high-tech solutions and determining which companies could deliver on time and on budget Danhongovernment digital services and technology experts.
Three former 18th floor employees who requested anonymity had recently cut jobs New Scientist. It helped digitize the healthcare application system to make states easy access to federal Medicaid funds. These provide health insurance to 70 million Americans, including 40% of all children and 60% of all nurse residents.
Another former employee interactively collaborated with the US Department of the Interior Website This tracks environmental damage caused by the release of petroleum or other harmful substances. Such data helped ensure that the person responsible for the damages, not the taxpayer, would pay to clean it, they said.
Members of the 18th floor also had the National Weather Service updated. Prediction website To make it more user-friendly. The 18F team worked with USDS to develop a free direct file program. This allows participating states to submit their taxes directly to the Internal Revenue Service, instead of purchasing tax preparation software or hiring an accountant. The government estimates that more than 30 million taxpayers from 25 states will be eligible for services in 2025.
The future of these projects is currently uncertain. Since President Donald Trump began his second term in January 2025, he has changed his name, I'll remake it The USDS is a clumsy USDS, led by government civil servant Amy Gleason, but is actually led by high-tech billionaire Elon Musk. Many previous US digital services members have since been fired or resigned.
Musk I was aiming It was on the 18th floor early in Trump's second administration, but former 18th floor employees had not received official “forced” notifications to close the organization until February 28th. Approximately 85 members on the 18th floor were directly affected by the layoffs, and three more received previous acquisition offers.
The combination of 18F exclusion and layoffs and resignation from the previous USDS team means there is no government-wide mission left to develop and build technology. say Former 18th floor employee. A spokesman for the General Services Agency (GSA), a US government organization that provides operational support to all federal agencies, said: “GSA will continue to support the administration's willingness to adopt best-in-class technologies to accelerate digital transformation and modernize IT infrastructure.”
Male chimpanzees may have sexual contact during stressful periods
Jake Brooker/Chimhunsi Wildlife Orphanage Trust
Some chimpanzees seem to use sexual behaviors like genital rubbing to manage stressful situations. This shows that our closest living relatives – or in fact, as we thought, isn’t that different from highly sensitive bonobos.
Jake Brooker Durham University in the UK and his colleagues investigated the sexual behavior of non-human primates Rolaya Bonobo Sanctuary The Democratic Republic of the Congo and Chimhunsi Wildlife Orphanage Trust In Zambia. Both sanctuaries contain a mixture of wild and captive-born apes, allowing them to roam freely and forage within them.
Researchers observed 53 bonobos (Pampaniscus) It spans three groups: Lola Ya Bonobo and 75 chimpanzees (Pantrogloid) across two groups of chimhunsi over the course of the feeding event of events, including swings distributing limited supply of peanuts to specific regions.
“Bonobos and chimpanzees both live in extremely complex social structures. Zanna Clayat Durham University. Predicting such feeding events can be stressful due to the competition for those who will first reach the food.
Researchers observed 107 instances of genital contact in bonobos and 201 instances of chimpanzees five minutes before 45 feeding events in five groups.
“This involves placing your hands or feet in another primate's biogenic area, and it could also involve the genital organs that touch each other, like the bonobo's very well-known genital friction behavior,” says Brooker.
This study revealed differences between species. “We found that sex frequency in these situations was more common in other women and female bonobos, but more common among chimpanzee men,” says Clay. It may be related to the fact that bonobos live in patriarchal groups, but chimpanzees live in patriarchal groups, she says.
“By using sex as a social tool to navigate all kinds of social issues, bonobos have given them a bit of a reputation as a kind of sexy hippie ape,” says Clay. “This study shows that the differences between the two species are not as large as previously assumed. Chimpanzees are known to be aggressive and violent, but in reality they have a truly rich repertoire of behaviors used to manage social life.”
“Chimpanzees definitely draw PR short straws compared to bonobos.” Matilda Brindle At Oxford University.
Chimpanzees use sex in ways that go beyond breeding, unlike human sexuality, but we don’t just have sex for breeding, says Clay. for example, Stress reduction It was given as a reason for people to have sex.
Kit Opie At the University of Bristol in the UK, I wonder if the same level of behavior can be seen in wild environments rather than sanctuaries.
The work may also shed light on our last common ancestors, who lived around five to seven million years ago, before humans branch out from dicks and bonobos, he says.
“If we consider that all three use sexual behaviors to navigate social relationships, it is likely that the common ancestors we share did too,” Brindle says.
The first water molecules could have formed just 100 million to 200 million years after the Big Bang – even the first galaxy kicked off the processes that led to life on Earth.
Shortly after the Big Bang, most of the problems in the universe were hydrogen and helium, with only traces of other lighter elements, such as lithium. Heavy elements like oxygen are not yet present, and water is impossible to form.
These early elements were combined into the first star and produced heavier elements through oxygen-containing fusion. When these stars reach the end of their lives, they explode as supernovae, releasing these heavier elements, allowing oxygen to mix and mix with existing hydrogen to combine H.2O – Water.
Previous research It shows that even the relatively small amount of oxygen produced by the earliest stars could create water molecules, but they say up until now they have not simulated exactly what happens when a protostar becomes a supernova, and how the elements it released blended with the cosmic environment in which the stars were formed. Daniel Warren At the University of Portsmouth, UK. “To do anything less, you just don't know what's going on,” he says.
To investigate this, Whalen and his team used computer models to simulate the birth and death of the first star in a realistic context. These early stars are thought to range from 13 times the massive range of the Sun to 200 times the size of the Sun, so researchers modeled both extremes.
As you can imagine, the larger stars spit out more oxygen and produced more water in the form of steam clouds around the Jupiter mass, while the smaller stars produced Earth's mass, says Whaleen.
Depending on the mass of the star, researchers discovered that water took between 3 million and 90 million years after the supernova explosion. In other words, the first water molecules were formed 100-200 million years after the Big Bang.
Importantly, however, the team discovered that this water was not simply spreading throughout the universe. Instead, gravity caused it, and the other heavy elements produced by the first star were clumped together. That meant these chunks were breeding grounds for the second generation stars, and perhaps the first planet. “It was a huge result,” Whalen says.
“Even before the galaxy took place, this idea of water forming essentially overturning decades of thought about the first emergence of life in the universe,” says Whalen. Team Members Muhammadratif At UAE University, researchers now say they will simulate whether water vapor can survive the destruction of the formation of the first galaxy and harsh radiation.
“We know that the chemistry of life we know requires liquid water and can only be obtained in objects with surfaces in the universe or atmospheric.” avi loeb At Harvard University. It would have been a lot of time before this initial vapor condense into liquid water, but he says it could have helped them to find second-generation stars and their planets using instruments like the James Webbspace Telescope to help them understand this process more, and perhaps these planets could have been habitable millions of years after the Big Bang.
A scientist with a Ph.D. issues tsunami alerts and serves as a Hurricane Hunting Flight Director. Researchers investigate communities that are prone to flooding during storms.
They were part of over 600 workers who were laid off last week by the Trump administration, resulting in around a 5% reduction in the workforce of the National Weather Service and the National Oceanic and Atmospheric Administration (NOAA).
Kayla Besong, a physical scientist at the Tsunami Warning Center, was one of the affected employees. She played a key role in the safety monitoring team, which was reduced from 12 members to 11. She was responsible for programming a system that assessed the risk to the U.S. coastline and issued alerts accordingly.
The layoffs have raised concerns about the impact on public safety programs and the ability to deal with the increasing frequency of weather disasters due to climate change. Last year alone, NOAA recorded a $27 billion disaster that resulted in 568 deaths in the U.S., marking the second-highest death toll since 1980, accounting for inflation.
Meteorologists are facing challenges and criticism, despite their improving accuracy in predicting weather events. The Trump administration’s decision to cut jobs at NOAA has been met with protests and legal challenges. Experts warn that these cuts threaten progress and could hinder crucial scientific advancements.
NOAA has declined to comment on the layoffs, emphasizing its commitment to providing timely information and resources to the public. Former agency officials argue that the cuts jeopardize public safety, especially during weather emergencies.
Congressional Democrats have also opposed the layoffs, citing the impact on public safety and the ability to provide accurate weather forecasts. The cuts have affected essential roles, such as hurricane modeling specialists and flight directors, who play a vital role in predicting and responding to severe weather events.
The reduction in NOAA’s workforce has sparked concerns about the agency’s ability to effectively respond to upcoming weather seasons, potentially putting lives at risk and undermining public safety efforts.
Immediately after my 54th birthday, I received the package. The enclosed instructions said the next time I empty my intestines, I should shave a little of the stool, shave it into a small sample bottle, seal it in a prepaid envelope and drop it in a post. I did the act and a few weeks later I was invited to the hospital. My sample contained blood. Colonoscopy was ordered to rule out colorectal cancer.
Thankfully, I don’t have colorectal cancer. Colonoscopy of 54 is not a classic start to middle age. However, over the next few years, this particular rite of passage may begin to occur much earlier. The proportion of this cancer among people in my age group has been declining thanks to screening programs like this, but talking about under 50 years is much more troubling.
Early onset colorectal cancer (EOCRC) is now the circumstance, as is known in people under the age of 50, due to its virtually unprecedented nature of the 20th century. 10% of all new cases worldwide. That number is expected to more than double by 2030, and by then EOCRC is expected to be the most common form of fatal cancer among Americans aged 20-49.
The reasons are uncertain, but ambitious new projects explore potential causes. The idea is that EORC may also be a more clear and aggressive form of illness. Meanwhile, as routine screening expanded to younger groups – in January, the UK reduced the screening age to 50 – and the new, less invasive test…
Flowers and other plants need to pollinate insects to spread and reproduce. Their bright colours and intense smells attract bumblebees that pollinate them and play an important role in their survival. Without pollination, most fruits, vegetables, flowers and plants would not grow and diversify. Bumblebees eat nectar from flower to flower and collect them to store nutrient-rich pollen. In the process, their abdomen are covered in pollen. Pollen spreads from male flowers to female flowers as they fly between them. However, as global temperatures have risen in recent years, many scientists have noticed that bumblebees struggle to find colorful flowers and plants to pollinate.
This concern allowed a team of German scientists to take a closer look at how excessive heat affects bumblebees. They chose two types of Bumblebee to study: Bombus PascuorumAlso known as Carder Bumblebee Bombus Terrestris LinnaeusAlso known as bufftail bumblebee. These two bee species are common in Germany and most other parts of Europe, making them ideal options for research. Known as the ocean west coast climate, the region is a mild, comfortable summer and cool winter with plenty of rain.
Scientists suggested that heat waves due to climate change could affect how carder and bufftailed bumblebees survive during mild summers. In their study, the researchers exposed bees of both species to four different heat treatments and three different foods designed to replicate the scent of bees in the wild.
Scientists kept the bees in a comfortable, simulated environment a week before treatment. They then removed the individual bees and placed them in environments with different temperatures and humidity. Their goal was to simulate irregular weather phenomena such as drought and extreme heat and observe the bees' ability to find the scent of different flowers.
For each test, the researchers placed individual bees in long glass tubes to observe them. They performed their first treatment at 90% humidity and 104°F (40°C) to make the air very wet and hot. They performed a second treatment under the same humidity and temperature conditions, but added sugar syrup. They again administered a third treatment under the same conditions, but added a 24-hour rest period between heat and access to the sugar syrup. They had their fourth and final treatment at the same temperature, but only 15% humidity.
Scientists then applied the floral scent to Okimen, geraniol and nonnal on special absorbent paper and introduced it to each bee. They used a technique called to observe the electrical activity of bee antennas in response to odors Electrounnography. They explained that this process helps track bumblebee behavior after heat treatment.
Scientists have found that all heat treatments affect how bee antennae responded to the scent of three flowers. Specifically, we found that bufftailed bumblebees' sensory responses to flower scents reduced by up to 29%, while bufftailed bumblebees had a 42% to 81% reduction in their scent detection skills. Of all treatments, they found that the fourth treatment with low humidity had the greatest effect on honeybee sensation.
Scientists have concluded that research like theirs is useful when it is necessary to survive, taking into account the bees' experiences in the natural environment. With this in mind for global pollinators facing climate change, scientists have recommended that future researchers prioritize studying the effects of heat stress on cellular changes in bee antennas.
When it comes to sensitivity, the question of which generation is the most sensitive depends on who you ask. American Psychologist Dr. Jean Twenghe has conducted research comparing different cohorts and suggested that “millennials” (those born between 1981 and 1996) exhibit traits such as neurotic narcissism and anxiety more than previous generations. They tend to have unrealistically high expectations and struggle with criticism.
However, other studies have not always supported these findings. Research on nearly 500,000 American high school students between 1976 and 2006 found minimal differences in psychological characteristics across generations, including egoism and sensitivity to social status, which may indicate hypersensitivity.
Contrarily, some studies suggest that older generations may actually be more sensitive. A study from 2019 that analyzed hundreds of people born between 1923 and 1969 showed that those born earlier in the century exhibited greater signs of hypersensitivity.
Another study from 2024 focused on changes in narcissistic traits, including hypersensitivity, over the lifespan and across generations. It revealed that narcissism tends to decrease with age consistently across generations.
Overall, these studies suggest that hypersensitivity tends to decrease with age, with age being a more significant factor than the generation one belongs to. Some experts, like psychologist Professor Cote Rudolph, argue that the concept of individual generations like “Boomers” and “Gen X-ers” is arbitrary, and age and life experiences have a more significant impact.
This article addresses the question of which generation is the most sensitive, as asked by Madison Halladay from Jersey.

SpaceX is set to launch the Starship Megarocket on its upcoming test flight on Monday, approximately six weeks after the top stage of the vehicle exploded over the Atlantic during its final test.
Following the incident on January 16th, SpaceX lost contact with Starship about eight minutes after the flight, leading to subsequent explosions that scattered debris and small fragments near Turks and Caicos. Local authorities confirmed no injuries occurred.
The US Federal Aviation Administration initiated an investigation after the accident and grounded the rocket during the probe. On Friday, the agency announced clearance for the spaceship to resume flights, although the investigation remains ongoing.
SpaceX’s own investigation identified the “attic” section as the source of the leak that caused propellant to escape, triggering a fire and shutting down most of the spacecraft’s engines in a controlled sequence.

Data transmission ceased over eight minutes into the test flight, resulting in the vehicle disintegrating three minutes later.
Subsequent to the incident, SpaceX implemented several hardware and operational modifications to Starship’s upper stage, without disclosing specific details of the upgrades.
The eighth test flight for Starship, originally planned for Friday, encountered brief delays without explanation.
The FAA green-lit the flight, amidst broader fiscal and personnel reductions targeting various federal agencies during the Trump administration’s tenure. Reuters reported that the Government Efficiency Bureau, spearheaded by SpaceX’s Elon Musk, engaged with the FAA, with SpaceX engineers assisting as specialized government personnel.
The existence of Doge personnel within the FAA’s commercial spaceflight division overseeing private companies like SpaceX remains undocumented, prompting some lawmakers and critics, including Senator Ed Markey, to voice reservations regarding potential conflicts of interest.
The planned Monday launch aims to deploy four mock Starlink satellites mid-flight, marking the first payload release by the vehicle.
Upon separation from the second stage, Starship’s first Hull King stage is slated to return to the launch pad, where SpaceX intends to “catch” it using extensive mechanical equipment at the rocket’s launch tower. This stage was successfully retrieved during the January flight, signaling partial testing success for the company.
The catch maneuver is pivotal in SpaceX’s ambition to establish Starship as a fully reusable rocket system.
If the launch proceeds as planned, the upper stage will soar for about an hour on Monday before splashing down in the Indian Ocean off Western Australia.
Standing at 400 feet tall, the spacecraft constitutes the most potent rocket ever developed, comprising a super-heavy first-stage booster and an upper-stage spaceship.
Envisioned to play a crucial role in NASA’s moon missions, SpaceX has been selected by the agency to ferry astronauts during the Artemis III mission scheduled for 2027. Musk hinted at potential application for future Mars missions utilizing the spacecraft.
The personally built spacecraft is a few hours away from landing on the moon, a feat only achieved by one other company in spaceflight history.
The robot lander, known as Blue Ghost, has been orbiting the moon for approximately two weeks, gearing up for a daring descent. Firefly Aerospace, a Texas-based company, has developed a spacecraft with the goal of landing on the moon around 3:34 am early Sunday.
If all goes as planned, Blue Ghost will become the second privately owned vehicle to land on the moon. In February 2024, another Texas-based company, Intuitive Machines, made history with the Odysseus Lander successfully touching down near the moon’s Antarctic region.

Firefly Aerospace’s future landing attempts are set for 2025 as part of a robotic mission to the moon. Recently, Intuitive Machines launched its second lunar landing vehicle into space. Japanese company, The Ispace, was also sent towards the moon on the same rocket as Blue Ghost, taking a longer route but expected to arrive around late May or early June.
Blue Ghost is targeting a landing site in a 350-mile-wide basin near the moon’s surface, always facing the Earth. This area is believed to be the location of an ancient asteroid impact, according to NASA.
During a recent orbit around the moon, the Lander captured footage showing distant craters on the lunar surface.
Firefly’s Blue Ghost Lander filmed footage of the other side of the Moon on February 24th. Firefly Air Space
Blue Ghost is scheduled to begin its descent around 2 am on Sunday. NASA will broadcast live streams starting at 2:20 am ET on NASA TV.
Equipped with 10 NASA science instruments, the spacecraft will conduct various studies, including surveying the moon’s interior up to 700 miles deep, capturing Earth-focused x-ray images, analyzing space weather interactions with Earth’s magnetic field, and capturing detailed images during the descent for future missions.
The instruments onboard the Lander will examine lunar soil samples, study lunar dust adherence to different surfaces, and use lasers to measure Earth-Moon distance accurately.
Blue Ghost is expected to gather data on the moon for about two weeks.

This mission is part of NASA’s Commercial Lunar Payload Services initiative, a public-private partnership between NASA and US companies to deliver scientific experiments, technology, and cargo to the moon. It is a critical component of NASA’s Artemis program, designed to eventually return humans to the moon.
NASA allocated approximately $101.5 million to Firefly Aerospace to carry out the Blue Ghost Mission.
NASA states that the scientific experiments and technology demonstrations on these missions will enhance our understanding of the moon’s Antarctic region, where future human crews are expected to land.
The design of the flow headset resembles a prop from a futuristic movie, featuring a sleek curve and two large circular pads that utilize electrodes to deliver small currents to the brain.
Claimed to aid in treating depression, the company behind the headsets – Flow Neuroscience, priced at £400 (around $520) – boasts a 77% improvement rate in symptoms within just three weeks.
Initially skeptical, I am intrigued by the potential of wearable devices to enhance our well-being. However, I have encountered many grand claims in the past that failed to materialize.
Nevertheless, Flow’s compelling evidence could sway my opinion. Numerous studies have demonstrated the positive impact of the devices on individuals with depression, funded by Flow Neuroscience but conducted by external researchers and mental health professionals.
The most recent research, led by a team from East London University and involving 174 patients in the UK and US, revealed that 56% of those using the flow headset were symptom-free after 10 weeks, prompting consultant psychiatrist Alex O’Neill Kerr to emphasize the significance of these results.
“We’re talking about remission,” O’Neill Kerr remarked. “Symptom-free.”
O’Neill Kerr, who participated in a previous trial with the Northamptonshire Healthcare NHS Foundation Trust and prescribes the headset in his practice, shared anecdotes of how the device had transformed the lives of some patients.

“Upon initial use, I was astounded,” O’Neill Kerr noted. “Patients are regaining control of their lives. I recently spoke with an individual using a flow device, and it completely turned their life around.”
While not everyone benefits from using the headset, and not all research yields promising outcomes, recent studies have underscored the effectiveness of transcranial direct current stimulation (TDCS) in treating depression. By sending mild currents to the brain, TDCS stimulates less active areas associated with depression, potentially revolutionizing treatment for individuals who are unresponsive to traditional interventions.

O’Neill Kerr highlighted the potential of TDCS to address the underlying communication issues in the brain that lead to depression, offering hope to individuals who do not respond to standard treatments.
With milder side effects compared to traditional antidepressants, such as tingling sensations or headaches near the electrodes, TDCS presents a safer and non-addictive alternative that could be used in conjunction with conventional therapies.
While other TDCS headsets like Platowork and brain driver exist, Flow stands out as the sole device endorsed by the NHS due to its proven efficacy. Ongoing research aims to explore TDCS applications beyond mental health, potentially offering relief for conditions like anxiety, post-traumatic stress disorder, and tinnitus.
Envisioning a future where TDCS becomes a standard treatment option, O’Neill Kerr emphasized the profound impact it could have on patients. “It’s restoring your brain to its natural state,” he concluded.

Humans have been striving to measure the world we live in for a long time. Our measurement systems and units help us comprehend ourselves and our environment, whether we are dealing with basic physics theories or not.
When we measure something, we compare it to a standard benchmark to ensure accuracy and stability. The current benchmark for time is the atomic clock, which relies on the precise energy levels of electrons in an atom.
Atomic clocks, however, have limitations due to environmental factors affecting the energy levels within the atom. This has led to the exploration of nuclear clocks, especially using the rare thorium-229 isotope.
Thorium-229 has unique characteristics that make it an ideal candidate for creating nuclear clocks. Its nucleus has closely spaced energy levels that can provide more stable measurements of frequency and time compared to atomic clocks.
The recent advancements in using thorium-229 for nuclear clocks have opened up new possibilities for accurate time measurements and potential breakthroughs in fundamental physics theories.
Why go to the nuclear?
Nuclear clocks offer greater stability and accuracy compared to atomic clocks due to the small size of the nucleus and reduced influence from external factors. By utilizing thorium-229 and its unique energy levels, nuclear clocks can revolutionize time measurements.
These advancements in time measurement are not only essential for navigation and communication systems but also play a crucial role in testing fundamental physics theories such as relativity.
Accurate clocks can also help in exploring dark matter and understanding its interactions with normal matter. Nuclear clocks provide a more precise benchmark for detecting the effects of dark matter on time measurements.
What’s next?
The next step after harnessing thorium-229 for nuclear clocks is to develop a functional and reliable clock system. This involves stabilizing a laser to the frequency corresponding to nuclear energy levels and constructing a robust clock design.
While there are challenges in developing nuclear clocks, the potential for unprecedented accuracy in time measurement is promising. These advancements require in-depth calculations and understanding of fundamental forces like quantum chromodynamics (QCD).
Overall, the progress in nuclear clocks signifies a new era in precise timekeeping and could lead to significant advancements in our understanding of the universe and fundamental physics theories.
“Brain corruption” was named the term Oxford’s year 2024. This is defined as the “degradation of a person’s mental or intellectual state” that arises from seeing “trivial” content online, such as a Tiktok video.
It’s a term that is often joked about, but what If there is a grain of truth? This is the seemingly scary implications of a new study published by a large team of brain scientists based at Tianjin Division University in China.
What did this study find?
They scanned the brains of over 100 undergraduates and completed a survey on their habits of watching short online videos. The survey included statements such as “My life will be empty without a short video” and “Not able to watch a short video will be as painful as losing a friend,” indicating how much they agreed.
Interestingly, researchers found that those who felt most obsessed with short videos had significant differences in brain structure. These participants had more gray matter in the orbitofrontal cortex (OFC). This is an area near the front of the brain that is involved in decision-making and emotional regulation. Similarly, they had more gray matter in the cerebellum – the small cauliflower-shaped structures behind the brain play a role in movement and emotions.
The team concluded that this is bad news, as for Tiktok enthusiasts, having an oversized OFC could be a sign that it is described as “an increased sensitivity to rewards and stimuli associated with short video content.” They speculated that watching too many Tiktok videos could have led to this nerve distension.
Similarly, they suggested that enhanced cerebellum could help the brain process short video content more efficiently – perhaps the result of frequent rampages. This can create a reinforcement cycle. In this cycle, watching more videos strengthens these brain pathways and habits become even more ingrained.

But that’s not all. The team also performed a second brain scan to track participants’ brain activity while participants were resting with their eyes closed.
They found a greater synchronization of activity within multiple regions of the brain. These include the dorsal prefrontal cortex (areas involved in self-control), the posterior cingulate cortex (areas involved in thinking about oneself), the thalamus (a type of relay station for brain signals), and the cerebellum.
The researchers suggested that these functional brain differences could reflect a variety of issues among addiction participants. The issues include the tendency to overly social comparisons while having trouble leaving the video and watching them.
They also asked participants to fill out a survey on “promising temperament.” This is a factor measured by agreeing to statements such as “I strive to reach other people’s outstanding results.”
Interestingly, scientists have found that many links between video addiction and brain differences are also linked to a higher level of envy. This suggests that feeling of envy can make someone more likely to watch a short video. And over time, this habit can lead to potentially harmful changes in the brain.
Does Tiktok cause brain decay?
If you are an avid consumer of fun online videos, or a related parent, the idea that seeing habits can reconstruct brain structures is no surprise.
However, it is important to consider this study in a broader historical context in which new technologies and media have long been causing exaggerated neurological claims. It is also important to understand the deep limitations of research.
It’s been nearly 20 years Atlantic Ocean The magazine ran a cover function that asked, “Is Google making us stupid?” And, in a nutshell, the answer that was asserted was “Yes!” Author Nicholas Kerr lamented that he was once a “scuba diver in the sea of words,” but now, thanks to Google, he zipped “along the surface like a jet ski man.”
Countless brain imaging studies of questionable quality were also published in the same era. Many aim to demonstrate the disaster effect of the World Wide Web on our vulnerable minds.
A few years later, Professor Susan Greenfield, a neuroscientist professor of Baronness, launched a media campaign claiming that “mind change” (the impact of the internet and video games on the brain) is just as serious threat to humanity as climate change.
She even wrote dystopian novels about the dehumanizing effects of the internet, but received mixed reviews (One critic (I questioned whether this was one of the worst science fiction books ever written).
Scientists still don’t know how much Tiktok affects the brains of young people, but research is still underway. – Photo credit: Getty
Almost 20 years later, we’re fine. At least I don’t think our brains have been transformed into mash. But of course, these previous horrors were before the appearance of Tiktok. Perhaps there is something uniquely damaging about the types of short, scrollable, meaningless content available today.
I asked Professor Peter Etchellsif this is plausible, expert on the psychological impact of digital technology at Bathspa University. “As far as I know, there is no good science to support the idea that short videos are either tangible or uniquely bad in terms of their impact on the brain,” he says.

Is short video brain research a good science? Not so, but the evidence suggests that it is not.
What is wrong with this research?
Let’s take a look at some of the limitations of the research. If the goal was to prove that seeing tiktok is harmful to the brain, a more effective approach would be to scan participants’ brains and then consume different amounts of harmful content.
However, this study is completely cross-sectional, meaning that only a single snapshot was captured in time. This was not a pre- and post-comparison of causes and effects.
Or, as Etchell says: “[From this study] I can’t say anything about whether watching a short video will cause brain changes, or whether certain types of brain structures precede certain types of video consumption.
“This research doesn’t really add anything that will help us understand how digital technology affects us.”
Even if we accept the speculative leap of researchers that Tiktok’s videos may have caused the brain changes they observed, there are still some issues to consider.
First, the researchers searched the entire brain for differences that correlated with the scores on the video addiction scale. This approach is a common problem in brain imaging studies as it increases the risk of finding false positives. In other words, the more comparisons you make, the more likely you will stumble over random differences that seem important but are actually just a coincidence.
Second, even if we accept that the observed brain differences are real and caused by seeing Tiktok, interpreting them involves a lot of speculation. Researchers enveloped an increase in brain synchronization (known as regional homogeneity (Reho). However, Rejo itself is not inherently a good or bad thing. In fact, other studies have associated with an increase in Reho in certain brain regions. positive Results such as results observed during meditation training.
Perhaps the biggest flaw in the study relies on questionable survey-based measures of short video addiction that lacks strong scientific validity.
As Etchells put it, “Short video addiction is essentially an invented term, not a formal diagnostic clinical disorder.”
Taken together, these issues suggest that we should not be overly concerned that Tiktok fundamentally shapes the brains of young people in harmful ways.
That said, the excessive amount of time spent watching frivolous videos can still be a problem for some. However, it is more productive to focus on developing healthy media habits rather than worrying about brain changes or addiction.
“In many cases, when research like this hits the news, it’s a good opportunity to pause and reflect on whether we’re happy with the use of the technology,” says Etchells.
“If there’s concerns there, it’s worth thinking about what you can do to eliminate your frustration, knowing that you’ll benefit a lot from these technologies.”

New research suggests that Mars once was the perfect holiday destination (if they were willing to overlook radiation exposure or lack of food sources), but also had the right conditions for alien life. why? The discovery of ancient sandy beaches on the red planet suggests that once a large liquid ocean spread across the north of the planet.
“Looking back at the places where the earliest life on Earth developed, it was in the interaction between the ocean and the land, which paints a picture of an ancient habitable environment that can embrace the conditions for microbial life,” he said. Benjamin Cardenasassistant professor of geology at Penn State University in the United States and co-author of the study.
Four billion years ago, these beaches would have been the best variety. The waves are softly wrapped sandy and immersed in the sun.
“We found evidence of a lack of wind, waves and sand. It’s a proper vacation style beach,” says Cardenas, whose research was published. Proceedings of the National Academy of Sciences (pnas).
To find this, researchers used a probe up to 80m (260 feet) below the Mars surface in a region of North Mars called the Utopian Plain, using radar imaging, using a probe up to 80m (260 feet) below the Mars surface.
We discovered 76 hidden structures at depths of 10-35m (33-115ft). Sadly, this turned out to be not a mysterious alien infrastructure (we can dream of it), but rather a sedimentary deposit similar to what is found around the Earth’s coastline.
3.6 billion years ago, the ocean may have covered almost half of the red planet. The Orange Star shows where China’s Roberzouron began its exploration. Meanwhile, the Yellow Star is where NASA’s patient rover landed. Both arrived on Mars in 2021. -Image credit: Robert Citron
The structure, thickness and length of Martian sediments showed that they were not formed by the melting of rivers, winds, lava or ice, but rather by stable ancient seas. In fact, they were roughly the same as 21 people on Earth, including the Bay of Bengal.
Specifically, a formation called “foreshore sediments” is formed by the tide and wind that descends the slope towards the ocean at a 15° angle and carries sediments like sand and gravel.
“This quickly stood out to us because it suggested there were waves, meaning there was a dynamic interface between air and water,” Cardenas said. This interaction, which also took place in the early history of the Earth, is important for the beginning of life.
The discovery suggests that Mars had a warm, humid climate for tens of millions of years.
“We tend to think of Mars as a static snapshot of the planet, but it was evolving. The rivers were flowing, the sediment was moving, the land was built and eroding,” Cardenas said.
“This type of sedimentary geology tells us how the landscape looks, how they evolved, and, importantly, helps us identify where we want to look for our past life.”

Entomologists describe a new species of the Tiger swallow (genus genus) Papirio) From eastern North America.
Papilio Sorstian: (a) male, holotype and (b) female, arotype. Scale bar – 10 mm. Image credit: Derotler et al. , doi: 10.3897/zookeys.1228.142202.
Papirio It is a large genus of swallowtail butterflies within the family Papillonidae.
The only representative of the Papillionini family, the genus contains about 200 scientifically recognized species.
Newly identified members of the genus Papilio Sorstianbelongs to North America Papilio Glaucus Species group.
” Papilio Glaucus The group is a model research system for insect evolutionary biology. ” Dr. B. Christian Schmidt Arknides, nematodes and colleagues wrote on paper from the Canadian National Insect Collection.
“Recognition and boundaries” Papilio Glaucus and Papilio canadensis Three decades of study in speciation, host plant adaptation, hybridization, and molecular evolution have been conducted as a pair of classical sibling species. ”
“Recently, we have discovered a third species. Papilio appalachiansisprovided unprecedented insights into speciation by hybridization. ”
” Papilio Glaucus The group is primarily part of the clades of the subgenos of the New World clades on a large scale Pterourussometimes recognized as a distinct genus,” they added.
“The various within the group demonstrate adaptation to a variety of thermal niches that are warmly characterized (Papilio Glaucus), intermediate (Papilio appalachiansis), and cool (Papilio canadensis) Climate region; all have a wide larval host plant diet and are not limited by its distribution. ”
Papilio Sorstian It is closely related to these three species, but unlike all of the series of characters.
“The most important differences are evident in developmental biology and biology,” the researchers wrote.
“Papilio Sorstian Compared to May for all other species, it is unique during long delays in appearance after adult escape, starting from late June to early July to late June to early July. ”
Papilio Sorstian'The geographical range is Papilio Glaucus The southern end of Papilio canadensis.
“Core Range Papilio Sorstian It includes eastern and south-central Ontario, northern and central New York, and adjacent Vermont, New Hampshire and Pennsylvania.2The scientist wrote in his paper.
“In New York Papilio Sorstian He lives in most of the states except the Southeast and New York City metropolitan areas. ”
“In Canada, Papilio Sorstian It extends westward from Montreal, Quebec, to the Bruce Peninsula in Ontario and south to the Niagara region. ”
“The western limits seem to be on the east coast of Lake Huron. We haven’t seen any verifiable specimens of the west there.”
“Current evidence is consistent with the possibility Papilio Sorstian There is a recombinant evolutionary origin of Papilio appalachiansisThey added.
“However, the evolutionary origin of this kind, Papilio Glaucus-complex, I still can’t answer. ”
“Recognizing and defining the taxonomic identity of this unique evolutionary lineage is our hope to provide a staging point on the fertile grounds for future research.”

Taste hydrogels are administered to the mouth via small tubes
Shryn Chen
Electronic tongues that can replicate flavors like cake and fish soup can help you replicate food in virtual reality, but still can’t simulate anything else that affects taste, such as smell.
Yizhen Jia Ohio State University and his colleagues developed a system called e-Taste. This can solve a way to sample food and partially reproduce its flavor in someone’s mouth.
This includes using chemicals that correspond to five basic flavors. Sodium chloride, salty water, sour citric acid, glucose for sweetness, magnesium chloride for bitterness, umami glutamic acid. “These five flavors already explain the very large spectrum of food we have every day,” says Jia.
The system uses sensors to detect the levels of these chemicals in the food, convert them into digital measurements, pumping these values into a pump, and pushing a small amount of hydrogel containing different flavors into a small tube under a person’s tongue.
First, the researchers tested a system with a single flavor and asked how well the device reproduced sour on a 5-point scale, comparing it to a real sample of sour taste. They gave the same number for 70% of the time for the true sour thing that was reproduced.
The team then tested whether the system was able to replicate more complex flavors such as lemonade, cake, fried eggs, fish soup, coffee, etc., and asked a group of six if they could distinguish them, and felt they could have over 80% of the time.
However, I say it’s not very useful to focus on such flavors alone. Alan Chalmers Because other sensations are also involved in our taste at Warwick University in the UK. “Next time you have strawberries, close your nose and eyes. Strawberries are very sour, but are perceived as sweet because of their aroma and red colour. So if you send them just sour on your device, you’ll never know that they’re actually from strawberries.”
“This kind of electron can extract the amount of sweetness [and] It’s sour, but it’s not a taste for a human tongue,” he says.
If you’re like Khloe Kardashian, who recently turned 40, you may have considered testing your biological age to see if you feel younger than your actual age. But while these tests can tell you a lot about your body’s aging, they often overlook the aging of your brain. Researchers have now developed a new method to determine how quickly your brain is aging, which could help in predicting and preventing dementia. Learn more here.
Unlike your chronological age, which is based on the number of years since you were born, your biological age is determined by how well your body functions and how your cells age. This new method uses MRI scans and artificial intelligence to estimate the biological age of your brain, providing valuable insights for brain health tracking in research labs and clinics.
Traditional methods of measuring biological age, such as DNA methylation, do not work well for the brain due to the blood-brain barrier, which prevents blood cells from crossing into the brain. The new non-invasive method developed at the University of Southern California combines MRI scans and AI to accurately assess brain aging.
Using AI to analyze MRI brain scans, researchers can now predict how quickly the brain is aging and identify areas of the brain that are aging faster. This new model, known as a 3D Convolutional Neural Network, has shown promising results in predicting cognitive decline and Alzheimer’s disease risk based on brain aging rates.
Researchers believe that this innovative approach can revolutionize the field of brain health and provide valuable insights into the impact of genetics, environment, and lifestyle on brain aging. By accurately estimating the risk of Alzheimer’s disease, this method could potentially lead to the development of new prevention strategies and treatments.
Overall, this new method offers a powerful tool for tracking brain aging and predicting cognitive decline, bringing us closer to a future where personalized brain health assessments can help prevent and treat neurodegenerative diseases.
Giant panda (Ailuropoda Melanoleuca) It belongs to the Carnivora order, but they eat mostly bamboo and their unique dietary adaptability has always been the focus of their research. Recent studies have shown that plant-derived microRNAs (miRNAs) can release nanosized vesicles (40-100 nm) released by various cell types into the extracellular space and deliver to animal organisms via exosomes that exert cross-regulatory effects on gene expression. Chinese scientists collected blood samples from three groups of pandas (boy, adult female, and adult male) to investigate the role of plant-derived miRNAs in dietary adaptation of giant pandas and extracted them from blood for small RNA analysis. Their results show that plant-derived miRNAs enter the bloodstream of giant pandas, exert cross-kingdom regulatory effects, and may play an important role in the dietary adaptation process.
Giant Panda Cube Shaoriuu and his mother Baiyun at the San Diego Zoo.
“We have shown that plant-derived miRNAs are present in the blood of giant pandas,” says Dr. Feng Li, a researcher at West Normal University of China.
“Our research has proven that bamboo, which is used as food for giant pandas, affects changes in the feeding habits of giant pandas.”
In this study, the researchers took blood samples from seven giant pandas, including three adult women, three adult men and one boy woman.
In these samples, we found 57 miRNAs that are likely to be derived from bamboo.
“Bamboo miRNAs can enter the body of giant pandas through diet, absorbed by the intestines, enter the blood circulation, and regulate the RNAs of giant pandas as they transfer information and play a role in regulating gene expression in giant pandas,” Dr. Lee said.
These plant-derived miRNAs can regulate a variety of physiological processes, including growth and development, biological rhythms, behavior, and immune responses.
“Bamboo miRNAs are also involved in regulating the smell, taste and dopamine pathways of giant pandas, and all of these are related to feeding habits,” Dr. Lee said.
“When pandas eat more bamboo as they grow, certain miRNAs accumulate, regulating gene expression and aiding in their adaptation to bamboo’s flavor.”
“These miRNAs also affect the sense of the smell of giant pandas, and may allow you to choose the freshest and most nutritious bamboo plants.”
“Therefore, bamboo miRNAs may promote the adaptation of giant pandas from carnivorous to plant-based diets.”
The authors also found that pandas of different ages and genders have different miRNA compositions in their blood.
“Only miRNAs that can play a particular role in regulating gene expression can remain in the body, and those that do not play a role are expelled,” Dr. Lee said.
“For example, some miRNAs regulate reproductive processes and can only be found in the blood of pandas of a particular gender or age.”
“The fact that miRNAs can send signals from plants to animals could open the door to researching the treatment and prevention of diseases in animals.”
“Plant miRNAs also participate in regulating the animal’s immune system, increasing the disease resistance of animals.”
Similarly, studying miRNA-induced changes in plants can also help assess and improve the safety of plant-based foods in animals and humans.
However, more research is needed to draw decisive conclusions about the potential of common miRNAs and their impact on giant pandas.
“The giant pandas are an invaluable national treasure in our country, and blood samples are not easily obtained,” concluded Dr. Lee.
“If possible, we hope to collect blood samples of young pandas who have not yet eaten bamboo for research and perhaps get more surprising results.”

Impressions of the artists of Spherex Space Telescope
NASA/JPL-Caltech
The latest addition to NASA's Space Telescope Fleet will be launched this weekend and will soon scan the entire sky in near-infrared wavelength ranges, collecting a wealth of data on more than 450 million galaxies.
The history of the universe, the reionization epoch, and the spectrophotometer for Ice Explorer (Spherex) will be released on March 2nd on a SpaceX Falcon 9 rocket from the Vandenberg Space Force Base in California at 10:09 pm local time.
It carries a camera with filters that divide the light that enters like a prism and beams different parts of the spectrum into 102 separate color sensors. As the telescope pans around the sky, it slowly tightens the full image pixels pixel by pixel. This strategy allows you to use a relatively small and simple camera to do what you need to have a heavy, expensive suite of sensors, even without moving parts.
“If you slowly scan the sky slowly by moving the telescope, after a sufficient amount of time, every pixel in the sky is observed over a very wide wavelength range, giving you a coarse spectrum of every bit of the sky that has never been done before.” Richard Ellis University College London. “It's a very small space telescope, but it has some very unique features.”
Ellis says this rich dataset allows for accidental discoveries. “There's a high chance that you'll find something unexpected,” he says.
Infrared data is outside the human vision range, allowing scientists to determine the distance of objects and learn how to form galaxies. It can also be used to determine the chemical composition of an object, potentially revealing the presence of water and other important components.
The interesting stuff thrown by Spherex can be investigated in a more focused way using NASA's existing space telescope fleet.
Christopher Conseris At the University of Manchester in the UK, Spherex says it doesn't match the JWST solution or create similarly adoring images, but it says it will become a “maintainer” for scientific discovery.
“JWST can point to a part of the sky and take some big photos [and reveal] Something completely new. And Spherex really can't do the same thing,” he says. “It's going to be an analysis that takes years, and it's going to cover the sky many times.”
Spherex orbits the Earth 14.5 times a day away from the Earth's surface, completing 11,000 orbits over a two-year lifespan. Three cone-shaped shields protect the instrument from the Earth's radiant heat and interference from the sun.
The same rocket will be released on the polarimeter, another NASA mission to unify the Corona and Heliosphere Fair (punch), which will study the solar winds of the sun.
Hero Ideas Dengue fever boy Mosquitoes would have appeared in 2020 during the peak of the COVID-19 pandemic, when a dengue outbreak exploded in my hometown of Buenos Aires. Dengue fever spreads all the way Aedes aegypti mosquito. This insect thrives in tropical and subtropical climates and is commonly found in many warm and humid regions of Northern Argentina.
However, in recent decades, global warming has spread to traditionally cold, yet mild climates, such as Buenos Aires and Patagonia. One of my best friends had dengue fever in 2020, but as all media attention was focused on Covid-19, the city’s public hospitals had limited testing and there was no way to get proper diagnosis or treatment. Furthermore, there were no effective vaccines or medications for dengue at the time.
During this unsettling time for my friends and people with dengue in Argentina, US company Modern announced its vaccine against Covid-19 just a few days after the genetic sequence of SARS-COV-2 was issued. This has made me think about the terrible corporate bias in scientific research, as mosquito-borne diseases (dengue, zika, chikungunya, yellow fever, etc.) have killed hundreds of thousands of people over the centuries. In fact, mosquitoes are considered the deadliest animals for humans, according to historians. Timothy Wine Guardkilled more people than anything else in history.
However, these diseases affect people in low-income countries, so there was not enough investment in vaccines or treatments. Meanwhile, biotech companies only needed a few months to develop, patent and sell products that tackle Covid-19.
So, this idea came to me to tell the story of the global Southern pandemic through the lens of the mosquito itself.
Partly inspired by the artists I admire (Franz Kafka, David Cronenberg, Hidosi Hino), I leaned a bit ironically on Latin America’s most commercially popular genre, and I was convinced that the imaginary subtitles of my story should be “the self-capacity of a mosquito.” At the same time, one of the themes of my writing was inhumanity, and I was interested in the challenge of making insects the protagonist of a novel (a genre historically designed to tell the human age, psychology, and stories). How can we achieve this by mimicking and empathy with the human experience, especially insects that are as annoying as mosquitoes?
I became a mosquito and had to adopt that perspective. I have given the famous Frobertian motto.”Madame Bobbery, C’est Moi” And I changed it to my own: Le Moustite, c’est moi.
Ursula K. Le Gin once said The basic property of science fiction is to act as a carrier bag allowing for the transition of ideas from fiction to other scientific and technical discourses. This way, this genre becomes a mutational transition ( Dengue fever boy Between literature and non-literary knowledge.
I’ve always been very grateful for this idea. Because nothing in my work as a writer would please me more than studying topics I had never noticed before.
For this book, I consulted dozens of papers and manuals on entomology, and I became a “mosquito” overnight. It was important to know the details of mosquito anatomy, explain it, and understand how its body works and feels. Therefore, although the main character is inspired by my friend, a man, I discovered that the mosquito that tells the disease is a female.
The female perspective was also guided to investigating how non-mammalian oviparous animals are involved in maternal care. Eggs designed for films by HR Giger alien drawn and classified by the naturalist Ernst Heckel, in his illustrated treatise, Georges Bataille’s The story of the eyes It also fueled this oval obsession.
In this novel, I tried to tell a story about climate change from a perspective that restored human lives more than humans. I hope readers will resonate with my hero.

Michel Nieva's dengue boy is placed on a drowned future earth
Arami Stock Photo
Does that mean he's dead?
Dengue spreading the strange white surface under the Antarctic sun, and within a second, she saw everything flash. When you believe that a boy, a girl, a destroyed blank will die, how about life to look back at the space for a few moments? You might think of that dear mother. Do you lament your father who has never known or perhaps remembered a humorous or traumatic anecdote involving a classmate? Honestly, not many other things happened during her short time on Earth. However (the mind works in a mysterious and unpredictable way, especially the mind of a mutant mosquito), the destroyed dengue fever didn't think about any of these people, rather the story of her mother reading her at bedtime; Snow White and the Seven Dwarfs. She recalled the opening from her heart:
“Once upon a time, on a frozen, windy winter night, the Queen lived. This Queen watched snow fall as she knits by the window. From the window, the snowflakes slowly and rhythmically fell in an unpredictable pattern, like feathers from endless pillows. She was staring in wonder at the fall of snow, so she accidentally stabbed one of her fingers with a needle. Three drops of blood fell into the snow. And the Queen thought to herself. If I could have a daughter as white as snow, as blood red, as winter!”
This opening is always a volatile dengue boy (as he was at the time). In particular, he didn't understand half of the words: what the hell was it? winterwhat was it coldwhat was it snowand why did they spark such attraction?
A precious daughter snowjust as beautiful winter . . .
The mystery of those words, whose meanings had always escaped him, sparked even greater doubt.
It was impossible to know, and there was no empirical way to experience their effects in this future, when cold, winter and snow was gone from the earth (at least not for a miserable boy from Victoria). Naturally, his mother, who spent all her miserable lives at Victorica, didn't really help. All she knew (or as strong as she believes she knows) was that the snow was soft and beautiful, and that the beautiful child's skin had the same colour and pleasant texture, unlike the dengue children, who had a greenish yellow colour with furry skin. For this reason, the dengue boy, like some kind of qabalic rabbis, was convinced that he could access mystical meanings. cold, winter and snowhe will open up the secret of that mysterious sacred breast and how to get the love of his mother.
Because nothing had hoped that insects would turn white like snow and be as beautiful as winter.
The desire to access the mysterious material hidden in these words grabbed the poor insects and he cooperated with all the dictionaries and encyclopedias that he could find in search of answers. He read the definitions over and over again:
winter. noun. obs. The extinction season of the earth's age that occurred between autumn and spring has also become extinct.
Example: “Winter was the coldest time of the year.”
cold. noun. obs. Physical sensations produced by cold temperatures, the characteristics of ancient winters.
Example: “It was cold during the winter, especially if there was snow.”
snow. noun. Precipitation in the form of small white ice crystals formed directly from air water vapor at temperatures below 32°F. This occurs in terrestrial winters and occurs by artificial means on other planets or Earth.
Example: “There was a lot of snow in the winter!”
The poor boy reads these definitions, rereads them, then reads them again, but he has no understanding of his great disappointment. Is that because (as his classmates always argued) he was half wit? winter, cold, snow. Just words. words! Worse, it was a word that had to be explained using other words, and its definition was even more vague and inaccurate.
Wint-er, cold, sn-ow.
The herbular pictograph, which the boy tasted the phonemes through phonemes, was under the illusion that the flesh that once lay beneath the vivid skin had not evaporated before his eyes. But, although removed from the meaning that once brought them to life, what remained was a hollow corpse of meaningless sounds.
Wint-er, cold, sn-ow.
It was an atmospheric phenomenon that so many humans and other species suffered and endured for thousands of years, and now it was merely a planetary mystery, a speculative prose written by fossils, a biblical water and soil sky, a geological stamp!
The only season Pampas and the Antarctic Caribbean knew was summer, burnt, relentless, homogeneous. So when dengue became neutralised, her body still numbed from the poison, believing that she would die, and that she saw her own blood (to be precise, she saw blood that she indiscriminately sucked from Victoria's children and office workers), yes. Boy), a confused F story Snow White and the Seven Dwarfs.
And certainly, the memory she believed that her last body was worthy of was that her poisoned body actually landed on the ice rink of Great Winter Cruise, the flagship of the cruise company that traveled along the Antarctic Caribbean coast, recreating the cold season, and now disappearing from Earth, snow, glacier, and iceberg. Operated using AIS cutting-edge technology, these luxurious cruise ships allow tourists to experience the unique winter joys, including one of the biggest attractions, the largest ice rink on the planet.
And it was exactly where dengue died, ruining the fun of tourists. Imagine the scene: On this impressive slab of ice, 100 feet long and 55 feet wide, crowned the terrace of a 21 feet cruise ship, a massive crowd flocked to try a unique experience, perhaps for the first time, as large visitors were not present. Not only was it an opportunity to slide the unmistakably elegant ice skating strides on frozen sheets, but it was to do so at zero temperatures as the atmosphere in which the rink was installed recreated the harsh winter feel of old New York, lurking long under the waves. Plus, it was Christmas, the busiest and most eagerly awaited season in international tourism. And as the carols rang, the enchanting tourists dressed in fierce courts, moving like swans sliding down the Terra Incognita. It mimics the long-standing things at Rockefeller Center in Old New York, and there are also many leagues now under the sea.
Naturally, the sculptor hired on the cruise ship was sharp enough to replace the flames on Prometheus' right hand with a huge block of pure ice, and the Titans had taken from the deep by the planetary age, allowing these wealthy tourists to recover to the geologic era (as long as the cruise continues) which was permanently eclipsed eclocene to Earth. In fact, this was a cruise company slogan.Great Winter Cruise with 12,000 years of history in one place”, as humans promised to completely recreate the topography of a planet that lost winter, as humans knew it was born and died. Thus, “hibernation” (as the company called the advertising cruise experience) proceeded upwards from the floor, narrating winter history in ascending order. It began with a bottom deck that recreated the Pleistocene end in a giant fridge with robotic mammoths and mastodons, including a family-friendly game in which prehistoric mammals had to be set on fire with sticks and stones before they were attacked. The higher levels provided a variety of experiences from the old winter. Historic included the ability to invade Scandinavian cities on Viking ships, kill, sack, rape, or cross the Andes with General San Martin's white horse. Winter precipitation such as snow, hail, and sleet. There was also a huge igloo with outdoor cinemas, casinos, spas, carousels, cocktail bars and sushi and barbecue restaurants. Ancient frozen delights of ice, snow and cold were the real treasures of the gods stolen by Prometheus himself for the exclusive enjoyment of visitors to the cruise. The skaters slid across the rink in an atmosphere of pure joy, and were saved by Christmas carols, people clashing and dancing with each other cheerfully, shining and laughing at each other with the shared bliss. A true, unforgettable celebration recorded forever in the tourist retinus, a real dream, if mosquitoes had not landed violently on ice links and ruined everything.

Exciting news! There are new dancing animals in town, and they go by the name of Happy Feet. Recent research has uncovered the adorable jig that baby loggerhead turtles perform when they approach their favorite feeding spot.
A study captured the lively turtle movements, including tilting their bodies vertically, lifting their heads, opening their mouths, moving their front flippers in a paddling motion, and sometimes even spinning in place.
Researchers noted a distinct difference in the “turtle dance” behavior between feeding and non-feeding areas.
However, the study did not explore how these animals fare on the dance floor. The mystery of how turtles locate their favorite feeding spots during long migrations and lifetimes has intrigued scientists for quite some time.
New research suggests that turtles use Earth’s magnetic fields as a guide to identify the unique magnetic characteristics of their preferred feeding spots and celebrate with a dance when they find them.
In the experiment, researchers recreated two magnetic field signatures found worldwide, corresponding to locations near the Gulf of Mexico and New Hampshire, USA. Turtles were trained to associate each magnetic field with a feeding site.
The results showed that turtles exhibited more “turtle dance” behavior in designated feeding areas, indicating their ability to distinguish between the two magnetic fields.
“Sea turtles can sense both the strength and tilt of magnetic fields,” explained the lead researcher. “They not only detect these magnetic properties but also have a remarkable memory for them.”
This memory was evident as the turtles continued to recognize the designated feeding sites months after the initial experiment, even when not exposed to them. This demonstrates the turtles’ ability to navigate using magnetic cues and retain memories of specific locations.
Adult turtles have been observed returning to foraging sites after migrating for breeding, while baby loggerheads travel to coastal feeding grounds using ocean currents. Previous studies have shown their reliance on a “magnetic compass” for navigation, with the current research exploring their “magnetic map” capabilities.
The research team plans to delve deeper into these mechanisms in future studies to uncover how turtles perceive and use magnetic information for navigation.
There have been numerous ice age animals recovered from the world’s permafrost, ranging from woolly rhinos and wolves to urus, brown bears, and bison. Despite some being slightly damaged, they are often found in excellent condition.
One remarkable discovery was in 2017 when scientists excavated the remains of a small cave lion named Sparta from a frozen bank on the Siberian River. Although its golden fur was muddy and matted, its skin, soft tissue, and organs were all preserved. With closed eyes, it appeared more like a sleeping animal than one that had been dead for 28,000 years.
Another notable find was a two-month-old horse that died 35,000 years ago and was uncovered in Siberia in 2018. Though some fur was missing, the animal was largely intact, with hooves, skin, tail, and nostril hair preserved.
Various well-preserved woolly mammoths have also been discovered, some with grass in their mouths, milk in their bellies, and even dung on their bellies. While videos show people cutting into frozen mammoth carcasses and finding meat that looks fresh, the appearance can be deceiving.

While these ice age animals and their tissues may appear well-preserved superficially, zooming in reveals a different story. The lack of antifreeze agents when freezing live cells causes ice crystals to form, leading to cell bursting.
Although tissues and organs may seem intact, the cells that form them are not. The damage to these cells has occurred over the thousands of years since the last ice age ended. While these ancient animals may seem well-preserved on a larger scale, they are damaged at a microscopic level.
The most well-preserved ice age beasts are likely those with intact cells, which died closer to the end of the last ice age and have been frozen since. One such candidate is a 9,000-year-old bison discovered in the Russian Far East in 2022, which may have cells viable for cloning attempts.
However, cloning attempts on ice age animals have so far been unsuccessful due to DNA deterioration after death. Despite the optimism, the chances of successful cloning are slim. For now, appreciating these mummified artifacts as they are offers a fascinating glimpse into the ancient past.

Observe the night sky tonight to witness a rare event known as the “Planet Parade,” where the planets in our solar system align in a row. This phenomenon involves Mars, Jupiter, Mercury, Venus, Saturn, Uranus, and Neptune appearing in a straight line for a unique celestial display. This rare occurrence will not happen again until 2040.
The best time to view this spectacular event is on the evening of Friday, February 28th, 2025, when all seven planets will be visible in the sky. Astrophysicists like David Armstrong emphasize the significance of this planetary alignment and the rarity of such an occurrence.
To best observe this phenomenon, head outdoors just after sunset to catch a glimpse of Mercury, Mars, Venus, Jupiter, and Saturn. For a more detailed view, consider using binoculars or a telescope to see the distinctive features of each planet. Find a dark, remote spot away from city lights for the optimal viewing experience.
Where should I look to see the planets?
Identifying the planets in the sky can be challenging, but each has its unique brightness and position. Look for Venus in the west, the brightest object after sunset, followed by Jupiter overhead. Keep an eye out for Mercury, the closest planet to the sun, as it remains low on the horizon. The planets’ loose alignment creates a visual path across the sky, making it easier to track their movements.
Why is this planetary parade happening?
The alignment of planets is a result of their orbits in the zodiac plane, creating the illusion of alignment from Earth’s perspective. While this alignment is purely visual and does not have a significant impact on Earth, it provides a fascinating celestial display for observers to enjoy.
