During a routine hike with her husband in the Valtellina Orobie Mountains Park in Lombardy in 2023, Steffensen stumbled upon something unexpected. What seemed to be an ordinary rock lying along the path concealed a fascinating secret. Upon examining it more carefully, she discovered peculiar circular patterns adorned with wavy lines etched into its surface. Captivated by this find, she quickly understood that these markings weren’t mere coincidences – they were the footprints of animals!

Unsure of the significance of her discovery, Steffensen captured photos of the peculiar rock. These pictures would soon unlock a portal to a bygone era.  She shared the images with her friend, a nature photographer, who, in turn, forwarded them to paleontologists at the Natural History Museum of Milan. The moment the experts saw the intricate details; their hearts skipped a beat.

The museum team swiftly recognized the footprints as those of beings that walked the Earth an astonishing 280 million years ago! This era, referred to as the Permian, predates the existence of dinosaurs. It represented a vital chapter in the evolutionary history of life on our planet.

The discovery of the first rock, dubbed “Rock Zero,” was just the beginning. Further exploration in the area revealed a treasure trove of fossilized tracks on slabs of sandstone. These weren’t just isolated prints – the site held the remains of an entire prehistoric ecosystem, preserved in remarkable detail. Further investigation revealed hundreds of other fossilised footprints t made by over five species of ancient reptiles, amphibians and insects.

The fossil evidence extended beyond mere footprints. Researchers discovered imprints of prehistoric vegetation, featuring seeds and stems, which shed light on the plant life that flourished in this ancient ecosystem. Additionally, the site revealed impressions of raindrops, providing valuable information about the climatic conditions during the Permian period.

In a twist of irony, the melting glaciers in the Alps, driven by increasing global temperatures, have unveiled this ancient realm. Although this finding marks a significant scientific achievement, it also highlights the profound effects humanity has on the Earth.

The meme "Will Smith enjoying a plate of spaghetti" marks the inaugural AI benchmark meme.

Perhaps the sole one? View pictures in App save up to 80% data. AI video generators have made significant strides in their brief history, and an unexpected benchmark that many of us use to gauge this advancement has—due to various reasons—manifested as videos of Will Smith enjoying spaghetti. As one user pointed out on flight simulation forum AVSIM in late September 2024, these videos have become an AI benchmark. The difference in quality between the original AI-generated Will Smith eating spaghetti video—which went viral after it was posted to the r/stablediffusion subreddit by u/chaindrop in March 2023—and subsequent iterations—is stark. The AI improved significantly in movement, detail, and realism. About a year apart between these “Will Smith Eating Spaghetti” videos.

From a technical standpoint, it's quite a challenging task. AI generators have consistently struggled with accurately depicting food (which frequently appears distorted), hands (which seldom show the right number of fingers), and the intricacies of the eating process as a whole. Additionally, the abundance of noodles adds another layer of complexity for the AI to manage. But culturally speaking, as with any meme, the why doesn’t so much matter. It is as much a method of communication as it is an inside joke. Much like the Utah Teapot of the late ’70s and ’80s—a famous 3D model and computer graphics benchmark that was kind of a pre-meme meme—Will Smith eating spaghetti videos have become a cultural reference that breaches the gap between tech and pop culture. It has become an AI litmus test for the layman, a way for the culture at large to participate and track developments in the latest big tech wave. 2023 AI Will Smith eating spaghetti was comically gruesome. 2024 AI Will Smith eating spaghetti is plausible. 2025 AI Will Smith eating spaghetti might not be recognizable as AI at all (the actor’s real-life parody of the spaghetti-eating videos is undoubtedly hastening this certainty, providing generators with more exact data to replicate). At which point AI benchmarks will become more difficult to articulate and define, and memes will continue to feel more niche as the social internet grows increasingly fragmented. Tutto passa.

Elon Unleashes Cybertrucks, Combines Forces from SpaceX and Tesla for Humanitarian Mission in LA/Malibu

On November 21, 2019, Elon Musk, the co-founder and CEO of Tesla, showcased the newly revealed all-electric, battery-powered Cybertruck at the Tesla Design Center located in Hawthorne, California. (Frederic J. Brown - AFP / Getty Images) Elon Musk revealed that both Tesla and SpaceX have allocated resources and staff to assist those affected by the fires in Los Angeles, as residents are forced to evacuate and face the loss of their homes. Musk shared on Sunday evening via X that Tesla and SpaceX staffers are “driving around areas in greater LA/Malibu that are in tough shape with free WiFi, drinks & snacks.” Tesla & SpaceX personnel are driving around areas in greater LA/Malibu that are in tough shape with free WiFi, drinks & snacks https://t.co/304vjlXSoc — Elon Musk (@elonmusk) January 13, 2025 He shared a post from Tesla that outlined a “summary of initiatives” undertaken by the electric vehicle company to assist both its employees and the wider community. Those endeavors proved to be remarkably extensive. Tesla is providing housing accommodations, transportation, and meals for employees who had their homes “lost or destroyed” amid the historic fires. The company successfully restored all Supercharger locations to operation, with the exception of the Pasadena Supercharger, which was situated in the heart of the fire. Beyond those responses, Tesla deployed two Megapack Chargers, which are essentially massive energy storage units that help with grid reliability, on Friday to “relieve congestion in Thousand Oaks for evacuation & families losing power due to Public Safety Power Shutoffs.” The company deployed another unit the next day to Altadena “for first responder support, providing power & Starlink connectivity.” Tesla has dispatched an additional two Megapack Chargers to San Bernardino and is in the process of installing more in the Palisades, the areas that suffered the greatest damage from the recent fires. Mobile Powerwall Units have been set up in Altadena and Topanga Canyon with assistance from various nonprofit organizations to supply power for devices and refrigerators. Additionally, several Cybertrucks equipped with Starlink are stationed across the city, including in Altadena, Pasadena, Zuma Beach, and Malibu. The Cybertrucks are equipped with compartments filled with water and snacks. To put it differently, Tesla, SpaceX, and Musk have made significant efforts to support not just their employees, but also the entire community. Musk did the same after hurricanes destroyed large parts of the southeastern United States a few months back. However, the initiatives in California proceed in spite of some lingering tensions with the state's Democratic leadership. In November, California's Democratic Governor Gavin Newsom unveiled a proposal to provide rebates for electric vehicles, excluding Teslas. This decision has faced significant criticism, with many viewing it as a form of political revenge against a billionaire adversary who has recently allied with the Republican Party. Musk called the exclusion of Tesla “insane,” especially because the company is the only car producer to make electric vehicles in the Golden State, according to a report from the New York Post. In summary, while California's leaders chose to distance themselves from Musk, he remained loyal to the state. Even as Newsom whines about his enemies politicizing the fires, Musk going out of his way to help the state is about as unpolitical a move as he possibly could have made.

Are you able to decipher cursive writing? It's a unique skill that the National Archives is seeking!

View pictures in App save up to 80% data. View pictures in App save up to 80% data. If you have the ability to read cursive writing, the National Archives would be interested in hearing from you. Alternatively, there are several million. Over two centuries' worth of U.S. documents require transcription (or at the very least, classification), and the overwhelming majority of these are written in cursive handwriting – necessitating individuals who are skilled in this elegant, looping style of writing. "Being able to read cursive is like having a superpower," remarked Suzanne Issacs, who serves as a community manager for the National Archives Catalog in Washington D.C. She is part of the team that coordinates the more than 5,000 Citizen Archivists helping the Archive read and transcribe some of the more than 300 million digitized objects in its catalog. And they're looking for volunteers with an increasingly rare skill. Those records range from Revolutionary War pension records to the field notes of Charles Mason of the Mason-Dixon Line to immigration documents from the 1890s to Japanese evacuation records to the 1950 Census. View pictures in App save up to 80% data. An application for a Revolutionary War Pension submitted by Innit Hollister in August 1832. The National Archives employs Citizen Archivists, who volunteer their time to assist in transcribing these documents. While proficiency in reading cursive handwriting is beneficial, it is not a requirement. "Issacs mentioned that we organize missions inviting volunteers to assist us in transcribing or tagging records within our catalog." To volunteer, all that’s required is to sign up online and then launch in. “There's no application,” she said. “You just pick a pick a record that hasn't been done and read the instructions. It's easy to do for a half hour a day or a week.” Having the ability to read longhand script is incredibly beneficial, as many documents are composed in that style. "It's not solely about whether you were taught cursive in school; it's really about how frequently you utilize cursive in your daily life," she remarked. View pictures in App save up to 80% data. An application for a Revolutionary War Pension was submitted on April 29, 1852. The National Archives engages Citizen Archivists, who volunteer their time to assist in transcribing these historical documents. Being able to read cursive writing is quite beneficial for this task. Cursive writing has become less common. The ability of Americans to use this interconnected style of writing has been gradually declining over the years. School children were once taught impeccable copperplate handwriting and penmanship was something they were graded on. That began to change when typewriters first came into common use in the business world in the 1890s and was further supplanted in the 1980s by computers. Still, handwriting continued to be considered a necessary skill until the 1990s when many people shifted to e-mail and then in the 2000s to texting. By 2010, the Common Core teaching standards emphasized keyboard skills (once taught as “typewriting”) and no longer required handwriting on the presumption that most of the writing students would do would be on computers. That led to a pushback and today at least 14 states require that cursive handwriting be taught, including California in 2023. But it doesn’t mean that they actual use it in real life. In the past, most American students began learning to write in cursive in third grade, making it a rite of passage, said Jaime Cantrell, a professor of English at Texas A&M University Texarkana whose students take part in the Citizen Archivist work, putting their skills reading old documents to work. View pictures in App save up to 80% data. On January 23, 2024, a student at Orangethorpe Elementary School in Fullerton, California, is seen practicing cursive writing. This year, California grade school students are mandated to learn cursive handwriting as part of their curriculum. For people of her generation, she explained, “cursive represented a milestone in literacy during the 1980s. We mastered cursive and suddenly we could write in the same way that adults did.” She mentioned that although many of her students learned cursive in school, they rarely use or read it. She knows this because she provides feedback on their papers using cursive writing. A few of her students have stopped typing altogether. They now rely on talk-to-text tools or even artificial intelligence. "I can tell because the lack of punctuation makes it flow like a stream of consciousness," she observed. Mastering the cojoined script can be a challenging endeavor, but it is certainly achievable. Doing so grants you access to a treasure trove of historical documents. For many, cursive writing remains a valuable skill. California passed a law in 2023 requiring that “cursive or joined italics” be taught for grades one through six. The law’s author said it was so students could read primary source historical documents. That’s exactly how Cantrell’s students use it. One of the classes she teaches involves deciphering documents written in the 18th and 19th centuries – and one of their projects is to get involved in the National Archive’s transcription work. Cantrell remarked, “There’s definitely a learning curve involved. However, my students persevere. They sense a responsibility and believe they are contributing positively.” Being able to read cursive is just the start to deciphering older documents, said the National Archive’s Nancy Sullivan. The handwriting of the 18th and 19th centuries isn’t what today’s third-grader are taught. "Sometimes, the oldest texts can be the most straightforward to understand," Cantrell remarked. "Examining the correspondence between Abigail Adams and her husband, President John Adams, reveals that the cursive writing is truly an art form; it's remarkably consistent," she remarked. The capabilities of artificial intelligence in understanding cursive writing have their limitations. According to Sullivan from the National Archive, artificial intelligence is beginning to decipher cursive writing, but it still requires assistance from humans. The Archives has collaborated with FamilySearch, a non-profit organization focused on genealogy and operated by the Church of Jesus Christ of Latter-day Saints, which provides complimentary genealogical software, search capabilities, and access to historical records. FamilySearch has created an AI tool designed to interpret handwritten documents. However, a human is still needed to perform the final editing. "Typically, there are a few errors," she explained. "That's why we refer to it as 'extracted text,' and our volunteers need to review it and check it against the original document." It is only after a volunteer has thoroughly examined the text that it is deemed a proper transcription. According to Issacs, AI is not always able to interpret the frequently challenging documents that volunteers encounter. These documents may be damaged, stained, creased, or worn. For instance, when it comes to pension applications from the Revolutionary War, widows needed to validate their marriages, which led them to include handwritten pages of family trees that were often ripped out from their family Bibles. Let's not overlook the issue of poor penmanship. “The handwriting of some Justices of the Peace is dreadful,” remarked volunteer Christine Ritter, 70, a resident of Fairless Hills, Pennsylvania. The document is filled with cross-outs, notes scrawled on the reverse side that seep through, quirky and creative spellings, and archaic letter forms (for instance, a double S might appear as a "long s," resembling an F). Additionally, you'll find children's doodles layered on top. There are also numerous outdated terms and legal jargon that can confuse even the most knowledgeable readers. “It’s like piecing together a puzzle, and I find it truly enjoyable,” shared volunteer Tiffany Meeks, 37. She began her journey as a transcriber in June and discovered a new term – paleography, which involves interpreting ancient manuscripts. “I felt as though I was picking up a completely new language. I was not only revisiting my cursive skills but also my old English,” she remarked. “I discovered a new term: paleography,” which refers to the study of deciphering ancient texts. No cursive? That's perfectly fine! Issacs from the Archive emphasizes that volunteers are not required to have prior knowledge of cursive writing; you can pick it up as you go. "It can be beneficial, but it's not essential." For instance, there is a feature called "no cursive needed" available for individuals examining pension records from the Revolutionary War. Rather than directly reading and transcribing these documents, volunteers have the opportunity to assist by adding "tags" to records that have already been transcribed by fellow Citizen Archivists, making them more searchable. "You can learn it gradually as you progress," Ritter mentioned. "When I received the document for the first time, I was taken aback and thought, 'Wow, this is impossible to read.' It made me anxious. However, as I continued to work with them, it became much more manageable," she remarked. Ritter’s working on Revolutionary War pension files for soldiers who served at the Battle of Guildford Courthouse on March 15, 1781. As she works, she imagines how much it will mean to families to find something so old about one of their relatives. She recalls a time when she took great pride in her impeccable penmanship, but nowadays she describes her handwriting as “terrible.” Nevertheless, she still excels at reading cursive and has turned it into a delightful hobby. "I rise early in the morning and share breakfast with my husband before he heads out for a fishing trip. After that, I retreat to my workspace, where my computer awaits. I tune into my favorite oldies radio station and dive into my transcription work," she shared. "It's something I truly enjoy."

A Restful Night's Sleep Refreshes the Mind Similar to How a Dishwasher Cleans Dishes – Yet Caution is Advised with Sleep Medications.

View pictures in App save up to 80% data. Acknowledgment: Nadia Alzoubi and Natalie Hauglund Recent studies indicate that a restful night's sleep can refresh your mind, much like starting a dishwasher before sleeping and waking up to find everything tidy and organized in your thoughts. A team of scientists from around the world explains the process as a method of clearing out the waste that accumulates in the brain while we are awake. Their research also sheds light on how sleeping medications might interfere with the brain's "brainwashing" mechanisms, which could have lasting impacts on cognitive abilities. Scientists have discovered that the brain features an inherent waste clearance mechanism known as the 'glymphatic system.' This system facilitates the circulation of fluid within the brain and spinal cord to help eliminate waste. This process aids in eliminating harmful proteins that create sticky plaques associated with neurological conditions like Alzheimer's disease; however, the underlying mechanisms that propel this system have been elusive until recently. Researchers at the University of Copenhagen in Denmark discovered that a molecule known as norepinephrine is crucial for the brain's cleansing process in mice. In the deep stages of sleep, the brainstem emits small bursts of norepinephrine approximately every 50 seconds. The lead researcher of the study, Professor Maiken Nedergaard from the University of Rochester in New York, elucidated that norepinephrine causes blood vessels to constrict, producing slow pulsations that establish a rhythmic movement in the adjacent fluid, facilitating the removal of waste. She remarked, “It’s similar to starting the dishwasher before heading to sleep and waking up to a refreshed mind.” "We're fundamentally exploring the factors that influence this mechanism and aiming to characterize restorative sleep through the lens of glymphatic clearance." In their quest for clues, she and her team investigated the effects of sleep on mice brains. Their primary focus was on the connection between norepinephrine levels and blood circulation during deep sleep phases. Researchers discovered that fluctuations in norepinephrine levels are linked to changes in brain blood volume, indicating that norepinephrine may initiate a rhythmic pulsation within the blood vessels. The researchers subsequently analyzed the relationship between variations in blood volume and the flow of fluid within the brain, discovering that fluctuations in brain fluid flow align with changes in blood volume. The blood vessels function as pumps, driving the adjacent brain fluid to remove waste materials. "Think of norepinephrine as the conductor of an orchestra," said Dr. Natalie Hauglund, the lead author of the study from the University of Copenhagen and the University of Oxford. "The rhythmic contraction and expansion of the arteries create a balance that propels the cerebro-spinal fluid through the brain, effectively eliminating waste materials." Dr. Hauglund subsequently inquired whether all types of sleep were essentially the same. In order to investigate, the research team administered zolpidem, a widely used sleep aid, to mice. Researchers discovered that the norepinephrine levels during deep sleep were reduced by 50% in mice treated with zolpidem compared to those sleeping naturally. While the zolpidem-treated mice did fall asleep more quickly, there was a significant decrease of over 30% in fluid transport into the brain. The researchers say their findings published in the journal Cell show that the sleeping pills likely disrupt the norepinephrine-driven waste clearance during sleep—and the findings probably apply to humans, as well, because also have a glymphatic system. Researchers have detected comparable patterns of norepinephrine waves, blood circulation, and cerebrospinal fluid movement in humans. “More and more people are using sleep medication, and it’s really important to know if that’s healthy sleep,” said Hauglund in a media release. “If people aren’t getting the full benefits of sleep, they should be aware of that, so they can make informed decisions.” Their research might also shed light on the ways in which inadequate sleep could play a role in the development of neurological conditions like Alzheimer’s. "With our understanding that norepinephrine plays a key role in the brain's cleansing process, we may be able to discover ways to promote longer and more restorative sleep for individuals," Professor Nedergaard concluded.

China's 'Batwoman' researcher continues to carry out hazardous coronavirus experiments despite concerns over lab leaks.

Chinese researcher Shi Zhengli, aged 60, remains actively engaged in studying bat coronaviruses in Wuhan. Leading virologists warn that her research could have a 'potentially catastrophic' effect as we approach five years since the onset of the Covid-19 pandemic. View pictures in App save up to 80% data. Chinese virologist Shi Zhengli has allegedly earned the nickname 'batwoman' (file). A Chinese scientist is still conducting "potentially catastrophic" research into coronaviruses five years on from the start of the Covid pandemic which claimed millions of lives worldwide, according to experts. Shi Zhengli, 60, is one of the world's leading scientists working on bat coronaviruses in Wuhan. She has reportedly earned herself the nickname "Batwoman" as a result. She was thrown into the spotlight in late 2019 when a new form of coronavirus emerged in the region, with some scientists questioning whether Covid-19 leaked from a lab. In December, a two-year congressional investigation into the pandemic concluded the "weight of the evidence" suggests a lab leak was responsible. US lawmakers said in the report: "More and more senior intelligence officials, politicians, science editors, and scientists increasingly have endorsed the hypothesis that Covid-19 emerged as the result of a laboratory or research related accident." View pictures in App save up to 80% data. Her ongoing research has been labeled as 'potentially disastrous' (file). Nevertheless, leading virologists assert that Zhengli's team is still engaged in potentially harmful coronavirus research in Wuhan. In a study released in Nature, she proudly highlighted her team's achievement in creating the first "tailored" coronavirus "receptors." This advancement could enable researchers to modify viruses, allowing them to infect various species, including humans. Robert Redfield, the director of America's CDC during the pandemic, told The Sun: "It's potentially dangerous research. You are taking a non-pathogenic virus and changing it so that it could end up being dangerous to humans. You may have a pathogen that is restricted to pigs - but now you could totally change it so that it's highly infectious to other species too. View pictures in App save up to 80% data. An expert notes that Zhengli is 'experimenting with bat viruses and altering their receptors' (file). "She is experimenting with bat viruses and altering their receptors, which could enable them to infect animals like cows or chickens. This is a risky move with potentially disastrous outcomes. It might lead to a new pandemic affecting either animals or humans." Dr. Alina Chan, an expert in genetic engineering, stated that it seems Zhengli's team has now succeeded in "isolating" additional novel coronaviruses. She expressed concerns that this research is "risky" and prompts inquiries about the intentions of Zhengli's team regarding the handling of these new viruses once they cultivate them in the laboratory.

Ancient Climate Record Retrieved from Antarctic Ice Sheet Remains Intact

View pictures in App save up to 80% data. The ice core extracted from Little Dome C. (PNRA/IPEV) A massive ice core sample extracted from Antarctica could hold the most ancient, continuous record of Earth's climate, extending over a million years into the past. If laid out flat, the complete length of the ice core, measuring 2,800 meters (9,186 feet), would stretch beyond the Golden Gate Bridge in San Francisco. Each meter-long segment contains up to 13,000 years of deep, compressed history, including bubbles of ancient air. Together, the evidence provides a baseline for our current climate crisis, and it could reveal more about past extreme climate change events that threatened human survival. "We have a strong indication that the uppermost 2,480 meters contain a climate record that goes back to 1.2 million years," says Julien Westhoff, chief scientist on the ground for the European Project for Ice Coring in Antarctica (EPICA). More analysis is required, but there is a possibility that the deepest sections of the drilling may hold ice from the pre-Quaternary era, which is over 2.5 million years old. View pictures in App save up to 80% data. A portion of the ice core. (PNRA/IPEV) The oldest ice uncovered in Antarctica so far dates back 2.7 million years, but Earth's movements pushed this ice into a shallower patch of frozen material, so it doesn't provide a continuous climate chronicle; it's more of a snapshot. Previously, the EPICA record for the oldest vertical ice core covered the last 740,000 years or so, and it was obtained in 2004. Ice cores are precious to scientists, because they trap particles, water isotopes, and bubbles of atmospheric gases, like carbon dioxide and methane. This allows researchers to reconstruct climates and environments in our planet's history. Recent drilling efforts in East Antarctica reveal information about a timeframe during which the Earth's glacial cycles unexpectedly extended, occurring between 900,000 and 1.2 million years ago. Some scientists suspect nearly 99 percent of early humans in Africa may have died out during this period of extreme cold swings, although that hypothesis remains contentious and is mostly based on modern genetic data. The newly retrieved ice core from Antarctica has the potential to uncover further insights into Earth's climatic changes during this period. Additionally, it is likely to validate the extent to which human-induced emissions have disrupted the planet's natural glaciation cycles. "This transition remains a scientific mystery, particularly regarding the role of greenhouse gases and ice sheet dynamics," Carlo Barbante, director of EPICA, told CNN. "This information allows us to grasp the complex connection between greenhouse gases and global temperatures spanning hundreds of thousands of years, extending now to 1.2 million years and potentially further." The extraction site of the recent drilling is called Little Dome C, in East Antarctica, and it was chosen because radar surveys revealed the presence of extremely thick ice here, layered like a cake, with a bottom that had not yet melted away. At 3,200 meters above sea level – high on Antarctica's central plateau – summer temperatures on Little Dome C sit around -35 ºC (-31 ºF) and often there are high wind speeds to contend with as well. Researchers at EPICA, including scientists from the British Antarctic Survey, had their work cut out for them. It took about 20 days just to deliver all their infrastructure and cargo to the site from a nearby research station. View pictures in App save up to 80% data. Storage of ice core samples. (PNRA/IPEV) As drilling commenced, an isotopic analysis system was capable of detecting glacial and interglacial cycles nearly instantly, with each segment of the ice core being retrieved from the earth. This is the reason why researchers at EPICA are making significant assertions so early in their study. Today, the Antarctic ice sheet holds 90 percent of our planet's ice. A drilling like this one, straight from its belly, could reveal just how Earth's southernmost continent came to hog most of its freshwater. Climate scientist Richard Alley, who was not involved in the recent drilling effort, told the Associated Press that EPICA's ice core was "truly, truly, amazingly fantastic." Alley forecasted, "They will discover amazing knowledge."

'Siberian Express' Set to Intensify January's Frigid Conditions in Central and Eastern Regions

View pictures in App save up to 80% data. January has delivered a bitterly cold experience for numerous residents in the central and eastern regions, and the arrival of the "Siberian Express" is set to intensify the icy conditions as we approach the weekend and the upcoming week. First up, a temperature roller coaster this week. A bout of arctic air currently entrenched over the Midwest and Northern and Central Plains will sweep toward the Northeast through Wednesday. Low temperatures will sometimes be 10 to 25 degrees below average into midweek. Following this event, the Plains and Midwest are expected to experience significant warming, with temperatures reaching 10 to 20 degrees above the seasonal norm by Thursday and Friday. This will result in afternoon highs climbing into the relatively mild (for January) range of the 30s and 40s across many regions. View pictures in App save up to 80% data. Present Temperature Readings The "Siberian Express" arrives this weekend. When arctic air spills into the U.S. during winter it can have one of multiple source regions. That includes Arctic Canada, Alaska, and in the case what lies ahead this weekend and early next week, Russia's Siberia region. Sometimes meteorologists call this the "Siberian Express" because of the cold air's geographic origins. Siberia ranks among the coldest places on the planet. For instance, several areas in the region recorded temperatures plunging close to minus 60 degrees Fahrenheit in the 24-hour period leading up to Monday morning in the U.S. Such extreme cold is a common occurrence during the winter months in Siberia. Considering the frigid origins, arctic air from this area can deliver a powerful impact as it moves southward into Canada and the United States. View pictures in App save up to 80% data. How frigid temperatures might become. In general, some locations might see their coldest lows of winter so far, while for others it might rival what they have already seen. Minneapolis may experience its first double-digit below-zero temperature of the season early next week. Chicago and Denver could experience their initial sub-zero temperatures of the season. Please remember that this forecast is several days out, so the low temperatures for Sunday through next Tuesday may change. We will provide more updates on the forecast later this week. Another undeniable fact is that wind chills will once again pose a threat to many starting early next week. View pictures in App save up to 80% data. Next Week's Predicted Morning Lows January's cold start is notable for one reason. Record-setting cold hasn't been widespread this month, but what we've seen so far plus what's to come makes it noteworthy from a persistence point of view. For the first 11 days of the month, temperatures in many regions east of the Rockies were generally below the average, according to NOAA's analysis. Particularly significant was the observation that areas in the Plains, South, Ohio Valley, and mid-Atlantic experienced temperature drops of 5 degrees or more below the norm. Aside from a short warm spell towards the end of this week, most of these regions will still experience the harsh effects of this chilly January trend as we move into the final days of the month.

Fletcher Distinguished Professor of Comparative Oncology Genetics at NC State, 'We have been studying two dog populations that are only 16 kilometers, or roughly 10 miles, apart, yet they exhibit significant genetic differences.'" "We aim to explore whether prolonged low-level exposure to environmental toxins like radiation and lead could account for some of these disparities." Breen serves as the lead author of the research. In earlier research, the team examined genetic variations throughout the genome and pinpointed 391 unique regions in dogs that were distinct between the two populations. Among these regions, several harbored genes linked to the repair of DNA damage. In their latest study, the researchers took a more thorough approach, exploring the dogs' genomes to uncover signs of mutations that might have built up over time. "Initially, we placed the genetic differences between two dog populations into context, revealing that the genetics of dogs from Chornobyl City closely resembled those of dog populations in Russia, Poland, and nearby regions," explains Megan Dillon, a Ph.D. candidate at NC State and the primary author of the research. "This allowed us to utilize the dogs from Chornobyl City as a control group for comparison with the dogs from the nuclear power plant." The research team initially focused on identifying differences at the chromosomal level, subsequently narrowing their investigation to smaller genomic intervals, and finally examining variations at the single nucleotide level. Their goal was to uncover abnormalities and signs of accumulated mutations in germ line DNA—alterations that take place in the DNA of reproductive cells and are inherited from parents to their descendants over generations. "Breen explains, 'It's similar to utilizing the zoom feature on your phone's camera to capture finer details; we begin with a broad perspective of a subject and then focus in closely.'" "It is understood that high levels of radiation exposure can lead to instability starting from the chromosomal level. Although this dog population is over 30 generations separated from the dogs that lived through the 1986 disaster, any mutations that might have provided a survival benefit to those original dogs would likely still be identifiable. However, we did not observe any such evidence in these dogs." Although researchers did not find any evidence of genetic mutation, they emphasize that this does not exclude the possibility that selective pressures may account for the differences observed between the two dog populations. "Dillon explains that, in human context, this situation resembles examining a population that has lived hundreds of years after the disaster occurred." "It’s conceivable that the dogs that lived long enough to reproduce possessed certain genetic traits that enhanced their survival chances. This suggests that there might have been significant selective pressure initially, and subsequently, the dogs at the power plant stayed isolated from the urban population. Exploring this question is a crucial next step that we are currently pursuing." The researchers highlight that these results are just a fragment of the broader context regarding how negative environmental factors can impact the health of both dogs and humans. "While many consider the Chornobyl nuclear disaster to be a localized radiological event in a remote part of Ukraine, the health risks extend far beyond that," explains Norman Kleiman, a co-author and professor of environmental health sciences at Columbia University School of Public Health. "This is attributed to the various other hazardous substances, such as heavy metals, lead dust, pesticides, and asbestos, that were dispersed into the environment during the cleanup and remediation efforts spanning over thirty years." "Although no one currently resides at the NPP or in Pripyat, prior to the Russian invasion, thousands of individuals were still employed there daily, engaged in remediation and construction efforts in the vicinity," Kleiman explains. "Examining companion animals such as these dogs provides insight into the potential health hazards that people may encounter." In addition to looking at the genetics of the dogs, the team also recently identified differences in ticks recovered from the dogs at the power plant and Chornobyl City and the prevalence of the pathogens they transmit. These results, published in the journal Parasites and Vectors, may reflect differential exposures to both ticks and microbes at the two locations. Kleiman emphasized, "The significance of ongoing research into the environmental health implications of major disasters like this cannot be understated. With our societies becoming more technological and industrialized, it is inevitable that we will face similar disasters in the future. We must comprehend the potential health hazards and identify the most effective ways to safeguard individuals." More information: Megan N.

Experts indicate the age at which you're most inclined to form lasting friendships.

Researchers have provided insights into why friendships formed during this period tend to endure for a significant length of time. View pictures in App save up to 80% data. I think we can all acknowledge that having friends is incredibly valuable. Yes, family is also important, but some studies have suggested that it is friendships that make more of a positive impact on your life - lifespan in particular. For example, a 2005 study in Australia found that people who had more friends than other participants tended to outlive those with fewer by 22 percent, Inc. reported last year. A separate study revealed that those with strong social ties had a 50 percent better chance of survival. View pictures in App save up to 80% data. Research indicates that individuals with robust social connections tend to have a longer lifespan (Getty Stock Image) As you age, you begin to realize that friendships can be transient; however, there are a handful of individuals who will remain your companions for a lifetime. According to experts, it ultimately boils down to timing. Research has shown that most people will at least maintain adolescent friendships into adulthood, reports The i In fact, a recent study conducted by the newspaper found that 83 percent of Brits over the age of 30 are still friends with people they befriended at school or college. Adolescence is typically characterized as the period ranging from ages 10 to 24. View pictures in App save up to 80% data. Studies indicate that friendships formed during teenage years tend to endure throughout a person's life (Getty Stock Image). It seems that there are compelling reasons why the friendships you build during that period are more likely to endure over the course of your life. Experts have described this moment as a 'pivotal time'. Sarah-Jayne Blakemore, a Professor of Cognitive Neuroscience at Cambridge University, stated: "Adolescence represents a crucial phase for forming friendships, and the bonds created during this period can last for many years." "It is a period of our lives in which we undergo large changes in our sense of self, and particularly our ‘social self’ - the way we depict ourselves to other people. This includes what peer group we want to be part of and our social relationships." View pictures in App save up to 80% data. Certain individuals maintain lifelong friendships (Getty Stock Image) The bonds of friendship established between the ages of 10 and 24 are strengthened because 'the brain is designed to prioritize new experiences' during this developmental phase. Many of these experiences will be linked to the friends we shared them with, making them deeply embedded in our memories. It is also proposed that the friends you make during that period play a significant role in shaping who you grow into as an adult. Blakemore stated, "During adolescence, the brain exhibits a high degree of plasticity and adaptability, especially in areas associated with social functions." "This indicates that your social surroundings, including the individuals near you and your relationships with peers, could significantly influence the growth and development of your brain."

Do Cows Actually Align Themselves With Earth's Electromagnetic Field?

In 2008, scientists analyzed satellite imagery of grazing cows and discovered something rather surprising. View pictures in App save up to 80% data. Presenting the cow compass! Image source: Labellepatine/Shutterstock.com. In 2008, a group of researchers examining deer and cattle made an intriguing discovery. They observed that both species, whether grazing or at rest, tend to orient their bodies along the north-south axis. "Farmers and attentive nature and countryside observers know that most cattle and sheep, when grazing, face the same way," the team explained in their study. "The farmers’ wisdom and experience indicate that cattle face into the wind, whereas sheep face away from the wind; the animals expose the maximum body surface area to the sun when sun basking in cold but sunny times of the day." Although it is known that these animals often orient themselves in a specific direction while grazing, there has been limited scientific research into the reasons behind this behavior. In their investigation, the research team examined Google Earth satellite images capturing cows grazing globally, observed roe deer during their grazing and resting periods, and studied the body imprints left in the snow by red and roe deer. While they tried to consider elements like wind direction and the Sun's position in the sky, the researchers ultimately discovered that all these animals consistently aligned themselves along the magnetic north/south axis in statistically significant proportions. "The team stated, 'Since climatic elements such as wind, sunlight, or temperature do not seem to be prevalent directional influences that account for the widespread alignment, we deduce that the magnetic field is the sole and most probable factor responsible for the observed orientation.' They further added, 'Our examination of cattle in areas with naturally high positive and negative declinations offers compelling evidence supporting the notion that the Earth's magnetic field serves as the guiding signal.'" Though a strange result, it's not entirely out of the realms of possibility. Some animals, generally smaller than cows and deer, have been shown to have magnetoreception, or the ability to perceive the Earth's magnetic fields. In fact, it's surprisingly common, and particularly useful in migratory birds, likely aiding navigation.  In a subsequent investigation, the researchers suspected they had discovered indications that "orientation behavior" might be interfered with by the extremely low-frequency magnetic fields produced by high-voltage power lines. The team emphasized that the exact mechanism behind the orientation behavior remains unclear, although there are several hypotheses.  "For instance, the radical pair hypothesis proposes an intimate coupling of magnetic sensing with vision. According to this hypothesis, magnetic fields are perceived as visual patterns, which are dependent on both field direction and intensity," the team wrote in their study. "Thus, it is conceivable that the oscillations of the direction and intensity resulting from the [Earth's magnetic field] and [alternating magnetic field] interaction may blur magnetically modulated visual patterns and, in turn, compromise or disrupt magnetic compass orientation." Although the concept is intriguing, it might be premature to discard your compass in exchange for a more entertaining cow compass. A recent investigation involving 34 cows, which had powerful neodymium magnets affixed to their collars, revealed that these animals exhibited no noticeable directional preference, regardless of whether they were equipped with the magnets. Additionally, the study included 2,428 daytime observations of 659 resting cattle in Portugal, conducted at times excluding the hottest parts of the day, and concluded that the cows tended to prefer facing southeast. The team suggests that instead of having magnetoreception, the phenomenon is more related to the position of the Sun. They conclude that earlier research might have been biased due to the reliance on Google Earth images captured on clear, sunny days. "We found a significant correlation between the animal’s orientation and the direction of the sun, minimizing sun radiation on the animal’s body, similar to what was observed in horses," the team wrote in their discussion. "Indeed, if most views were made on cloudless sunny days, then the animals were possibly reducing their body exposure to the sun. We thus believe that the cattle’s reported south-north alignment observed in earlier studies could perhaps, at least in part, be attributed to thermoregulation, possibly overriding a magnetic alignment. Similar sun-reducing behaviour has been observed in springbok and in black wildebeest, and was demonstrated to be linked to thermoregulation in those studies." In summary, additional and more detailed research might be required to understand the reasons behind cows' tendency to align themselves while grazing and resting. For now, it's best not to rely on them as a substitute for a compass.
