An anonymous reader shares a report: It's not the vibes; Earth is literally getting darker. Scientists have discovered that our planet has been reflecting less light in both hemispheres, with a more pronounced darkening in the Northern hemisphere, according to a study published on Monday in Proceedings of the National Academy of Sciences.

The new trend upends longstanding symmetry in the surface albedo, or reflectivity, of the Northern and Southern hemispheres. In other words, clouds circulate in a way that equalizes hemispheric differences, such as the uneven distribution of land, so that the albedos roughly match -- though nobody knows why. "There are all kinds of things that people have noticed in observations and simulations that tend to suggest that you have this hemispheric symmetry as a kind of fundamental property of the climate system, but nobody's really come up with a theoretical framework or explanation for it," said Norman Loeb, a physical scientist at NASA's Langley Research Center, who led the new study. "It's always been something that we've observed, but we haven't really explained it fully."

To study this mystery, Loeb and his colleagues analyzed 24 years of observations captured since 2000 by the Clouds and the Earth's Radiant Energy System (CERES), a network of instruments placed on several NOAA and NASA satellites. Instead of an explanation for the strange symmetry, the results revealed an emerging asymmetry in hemispheric albedo; though both hemispheres are darkening, the Northern hemisphere shows more pronounced changes which challenges "the hypothesis that hemispheric symmetry in albedo is a fundamental property of Earth," according to the study.

Scientists have discovered complex organic molecules within the icy plume erupting from Saturn's moon Enceladus, strengthening the case that its hidden saltwater ocean may harbor the conditions for life. The Guardian reports: The sixth largest of Saturn's moons, Enceladus has become one of the leading contenders in the search for bodies that could harbor extraterrestrial life, with the Cassini mission -- which ended in 2017 -- revealing the moon has a plume of water ice grains and vapors erupting from beneath the surface at its south pole. The phenomenon has since been captured by the James Webb space telescope, with the plume reaching nearly 6,000 miles into space. The source of this material is thought to be a saltwater ocean that lies beneath the moon's icy crust.

Now researchers studying data from the Cassini mission say they have discovered organic substances within the plume, with some types of molecule detected there for the first time. Dr Nozair Khawaja, a planetary scientist at Freie University Berlin and lead author of the work, said the results increased the known complexity of the chemistry that is happening below the surface of Enceladus. "When there is complexity happening, that means that the habitable potential of Enceladus is increasing right now," he said. Writing in the journal Nature Astronomy, Khawaja and colleagues reported how their previous work had revealed the presence of organic substances and salts within ice grains found in a ring of Saturn, known as the "E-ring," that is composed of material ejected from Enceladus. [...]

While the new findings do not show that there is life on Enceladus, Khawaja said they indicate there are complex chemical pathways at play that could lead to the formation of substances that could be biologically relevant. The results, he added, support plans by the European Space Agency (ESA) to investigate the moon for signs of life. "I think all the signals are green here for Enceladus," Khawaja said. The findings add momentum to ESA's proposed mission to directly search for biological signs around 2042. According to the ESA, the mission will consist of an orbiter around Enceladus that will also fly through the plumes, as well as a lander that will touch down in the south pole region of the moon.

Jane Goodall, world-renowned primatologist, anthropologist, and conservationist, has died at the age of 91 while on a speaking tour in California. The British primatologist's "discoveries as an ethologist revolutionized science, and she was a tireless advocate for the protection and restoration of our natural world," according to the institute she founded. From a report: Goodall was only 26 years old when she first traveled to Tanzania and began her important research on chimpanzees in the wild. Throughout her study of the species, Goodall proved that primates display an array of similar behaviors to humans, such as the ability to develop individual personalities and make and use their own tools. Among the most surprising discoveries Goodall made was "how like us" the chimpanzees are, she told ABC News in 2020.

"Their behavior, with their gestures, kissing, embracing, holding hands and patting on the back," she said. "... The fact that they can actually be violent and brutal and have a kind of war, but also loving an altruistic." That discovery is considered one of the great achievements of 20th-century scholarship, according to the Jane Goodall Institute. [...] Goodall's research garnered both scientific honors and mainstream fame, and she was credited with paving the way for a rise in women pursuing careers in STEM (science, technology, engineering and math) over the years. The number of women in STEM has increased from 7% to 26% in the six last decades, according to The Jane Goodall Institute, which cited census information from 1970 to 2011.

In 1991, she also founded Roots & Shoots, a global humanitarian and environmental program for young people. She was named a United Nations Messenger of Peace in April 2002. The anthropologist continued to lend her voice to environmental causes well into her 80s and 90s. In 2019, Goodall acknowledged the climate crisis and the importance of mitigating further warming, telling ABC News that the planet is "imperiled." "We are definitely at a point where we need to make something happen," she said.

"We are imperiled. We have a window of time. I'm fairly sure we do. But, we've got to take action." Goodall even partnered with Apple in 2022 to encourage customers to recycle their devices to reduce individual carbon footprint and cut down on unnecessary mineral mining around the world. "Yes, people need to make money, but it is possible to make money without destroying the planet," Goodall told ABC News at the time. "We've gone so far in destroying the planet that it's shocking."

alternative_right shares a report from Phys.org: For the first time, a new study has tested the effectiveness of trigger warnings in real life scenarios, revealing that the vast majority of young adults choose to ignore them. A new Flinders University study has found that nearly 90% of young people who saw a trigger warning still chose to view the content, saying that they did so out of curiosity, rather than because they felt emotionally prepared or protected. The findings published in the Journal of Behavior Therapy and Experimental Psychiatry aligned with a growing body of lab-based research suggesting that trigger warnings rarely lead to the avoidance of potentially distressing material.

An anonymous reader quotes a report from the BBC: US scientists have, for the first time, made early-stage human embryos by manipulating DNA taken from people's skin cells and then fertilizing it with sperm. The technique could overcome infertility due to old age or disease, by using almost any cell in the body as the starting point for life. It could even allow same-sex couples to have a genetically related child. [...]

The Oregon Health and Science University research team's technique takes the nucleus -- which houses a copy of the entire genetic code needed to build the body -- out of a skin cell. This is then placed inside a donor egg that has been stripped of its genetic instructions. So far, the technique is like the one used to create Dolly the Sheep -- the world's first cloned mammal -- born back in 1996. However, this egg is not ready to be fertilized by sperm as it already contains a full suite of chromosomes.

You inherit 23 of these bundles of DNA from each of your parents for a total of 46, which the egg already has. So the next stage is to persuade the egg to discard half of its chromosomes in a process the researchers have termed "mitomeiosis" (the word is a fusion of mitosis and meiosis, the two ways cells divide). The study, published in the journal Nature Communications, showed 82 functional eggs were made. These were fertilized with sperm and some progressed onto the early stages of embryos development. None were developed beyond the six-day-stage.

The technique is far from polished as the egg randomly chooses which chromosomes to discard. It needs to end up with one of each of the 23 types to prevent disease, but ends up with two of some and none of others. There is also a poor success rate (around 9%) and the chromosomes miss an important process where they rearrange their DNA, called crossing over. Prof Mitalipov, a world-renowned pioneer in the field, told me: "We have to perfect it. "Eventually, I think that's where the future will go because there are more and more patients that cannot have children."

Cancer rates among people aged 15 to 49 have increased 10% since 2000 even as rates have fallen among older populations. Young women face an 83% higher cancer rate than men in the same age range. A 150,000-person study presented at the American Association for Cancer Research meeting found millennials appear to be aging biologically faster than previous generations based on blood biomarkers. That acceleration was associated with up to 42% increased risk for certain cancers including lung, gastrointestinal and uterine malignancies.

Researchers are examining the "exposome" -- the full range of environmental exposures across a person's life. Studies have linked early-onset cancers to medications taken during pregnancy, ultra-processed foods that now account for more than half of daily calorie intake in the United States, circadian rhythm disruption from artificial light and shift work, and chemical exposures. Gary Patti at Washington University is using zebrafish exposed to known and suspected carcinogens to track tumor development. His lab has developed systems to scan blood samples for tens of thousands of chemicals simultaneously to identify signatures appearing more frequently in early-onset cancer patients.

BrianFagioli shares a report from NERDS.xyz: NASA has awarded Solstar Space a $150,000 SBIR Phase I contract to develop a Lunar Wi-Fi Access Point (LWIFI-AP). The system is designed to provide wireless connectivity for astronauts, rovers, and orbiting spacecraft as part of the Artemis and Commercial Lunar Payload Services programs. Solstar's goal is to build a space-rated, multi-band, multi-protocol access point that can survive radiation, extreme lunar temperatures, and other harsh conditions. NASA has identified Wi-Fi and 3GPP standards as core communication needs across mission systems ranging from the Human Landing System and Lunar Terrain Vehicle to the Lunar Gateway.

Although this is only an early-stage contract, Solstar's proposal addresses a clear gap in space-qualified networking hardware. The company says that just as Wi-Fi transformed daily life on Earth, it will be equally important for living and working on the Moon. If the project advances, astronauts could soon be relying on familiar wireless technology that has been adapted for one of the most challenging environments in existence.

Sen. Mark Kelly and three Democratic colleagues urged appropriations leaders to block funding for moving space shuttle Discovery from the Smithsonian's Udvar-Hazy Center in Virginia to Houston, arguing the transfer would waste taxpayer money, risk permanent damage, and restrict public access. The relocation, pushed by Texas senators Cornyn and Cruz under a new law, carries an estimated cost of nearly $400 million. Ars Technica reports: "Why should hundreds of millions of taxpayer dollars be spent just to jeopardize a piece of American history that's already protected and on display?" wrote Kelly in a social media post on Friday. "Space Shuttle Discovery belongs at the Smithsonian, where millions of people, including students and veterans, go to see it for free." In a letter sent on the same day to the leadership of the Senate Committee on Appropriations, Kelly and his three colleagues cautioned that any effort to transfer the winged orbiter would "waste taxpayer dollars, risk permanent damage to the shuttle, and mean fewer visitors would be able to visit it." "It is worth noting that there is little evidence of broad public demand for such a move," wrote Kelly, Warner, Kaine, and Durbin.

In the letter, the senators asked that committee chair Susan Collins (R-Maine) and vice chair Patty Murray (D-Wash.) block funding for Discovery's relocation in both the fiscal year 2026 Interior-Environment appropriations bill and FY26 Commerce, Justice, Science appropriations bill. [...] "Houston's disappointment in not being selected is wholly understandable," the four senators wrote, "but removing an item from the National Collection is not a viable solution." [...] "There are also profound financial challenges associated with this transfer," wrote Kelly. Warner, Kaine, and Durbin. "The Smithsonian estimates that transporting Discovery from Virginia to Houston could cost more than $50 million, with another $325 million needed for planning, exhibit reconstruction, and new facilities." "Dedicating hundreds of millions of taxpayer dollars to move an artifact that is already housed, displayed, and preserved in a world-class facility is both inefficient and unjustifiable," the senators wrote.

Then there are the logistical challenges with relocating Discovery, which could result in damaging it, "permanently diminishing its historical and cultural value for future generations." "Moving Discovery by barge or road would be far more complex [than previous shuttle moves], exposing it to saltwater, weather, and collision risks across a journey several times longer," the letter reads. "As a one-of-a-kind artifact that has already endured the stresses of spaceflight, Discovery is uniquely vulnerable to these hazards. The heat tiles that enabled repeated shuttle missions become more fragile with age, and they are irreplaceable." Kelly, who previously lived in Houston when he was part of the space program, agrees that the city is central to NASA's human spaceflight efforts, but, along with Warner, Kaine, and Durbin, points out that displaying Discovery would come with another cost: an admission fee, limiting public access to the shuttle. "The Smithsonian is unique among museums for providing visitors with access to a national treasure meant to inspire the American public without placing economic barriers," wrote the senators.

Researchers in Texas confirmed the first documented wild hybrid between a blue jay and a green jay -- a rare pairing that is likely a result of climate change and habitat shifts. Slashdot reader fjo3 shares a report from CNN: "We think it's the first observed vertebrate that's hybridized as a result of two species both expanding their ranges due, at least in part, to climate change," said Brian Stokes, a doctoral student of biology at the University of Texas at Austin and first author of the study published September 10 in the journal Ecology and Evolution. The vividly colored green jay is found in parts of South and Central America, Mexico and a limited portion of southern Texas. But since 2000, the tropical bird's territory has expanded north by hundreds of kilometers -- more than 100 miles and about 2 degrees of latitude -- along the Rio Grande and up toward San Antonio, said study coauthor Timothy Keitt.

Avid birders across Central Texas have taken note, sharing sightings of the emerald birds on social media and apps like eBird. Keitt, a professor of integrative biology at UT Austin, has been keeping tabs on their rapid northward creep since 2018. "They're pretty unmistakable in the field," he told CNN. "You see a green jay and you absolutely know that it's a green jay." Stokes joined Keitt's project a few years later, trapping birds to take blood samples for genetic analysis and releasing them back into the wild. While monitoring social media for green jay sightings in May 2023, Stokes came across an intriguing post on a Facebook group called Texbirds. A woman in a suburb of San Antonio shared a photo of an unusual bird that didn't look like any jay Stokes or Keitt had ever seen.

"He happened to notice that this person posted a picture of this odd jay, and immediately told me, and we got in the car and drove down to find it right away," Keitt said. He and Stokes described their finding as one of the "increasingly unexpected outcomes" that arise when global warming and land development converge to drive animal populations to new habitat ranges. This, they wrote, can lead to unpredictable animal interactions -- in this case, between a tropical species and a temperate one -- and create never-before-seen ecological communities.

A review of 62 scientific studies published in Osteoporosis International found that microplastics weaken bones by disrupting bone marrow stem cells and stimulating osteoclasts, cells that degrade bone tissue. Laboratory experiments found the particles reduce cell viability, induce premature cellular aging, modify gene expression, and trigger inflammatory responses. Animal studies found microplastic accumulation decreases white blood cell counts and deteriorates bone microstructure, creating irregular cell structures that increase fracture risk. Rodrigo Bueno de Oliveira from the State University of Campinas in Brazil said the effects interrupted skeletal growth in test animals.

"As awareness grows around the dangers of head trauma in sports, a small number of professional fighters and football players are turning to a psychedelic called ibogaine for treatment," reports the Los Angeles Times.

They note that the drug's proponents "tout its ability to treat addiction, post-traumatic stress disorder and traumatic brain injury, or TBI. " Ibogaine, which is derived from a West African shrub, is a Schedule 1 drug in America with no legal medical uses, and experts urge caution because of the need for further studies. But the results, several athletes say, are "game-changing".... Although athletes are just discovering ibogaine, the drug is well known within the veteran community, which experiences high rates of brain injury and PTSD. In Stanford's study on the effects of ibogaine on special forces veterans, participants saw average reductions of 88% in PTSD symptoms, 87% in depression symptoms and 81% in anxiety symptoms. They also exhibited improvements in concentration, information processing and memory.

"No other drug has ever been able to alleviate the functional and neuropsychiatric symptoms of traumatic brain injury," Dr. Nolan Williams, a professor of psychiatry and behavioral sciences, said in a statement on the results. "The results are dramatic, and we intend to study this compound further...."

States can work faster than the federal government by carving out exemptions for supervised ibogaine therapy programs, similar to what Oregon has done with psilocybin therapy. Many states have also opted to legalize marijuana for medicinal or recreational use... In June, Texas approved a historic $50-million investment in state funding to support drug development trials for ibogaine, inspired by the results seen by veterans. Arizona legislators approved $5 million in state funding for a clinical study on ibogaine in March, and California legislators are pushing to fast-track the study of ibogaine and other psychedelics.

"The internet is full of people claiming to uncover conspiracies in politics and business..." reports the Wall Street Journal.

"Now an unlikely new villain has been added to the list: theoretical physicists," they write, saygin resentment of scientific authority figures "is the major attraction of what might be called 'conspiracy physics'." In recent years, a group of YouTubers and podcasters have attracted millions of viewers by proclaiming that physics is in crisis. The field, they argue, has discovered little of importance in the last 50 years, because it is dominated by groupthink and silences anyone who dares to dissent from mainstream ideas, like string theory... Most fringe theories are too arcane for listeners to understand, but anyone can grasp the idea that academic physics is just one more corrupt and self-serving establishment... In this corner of the internet, the scientist Scott Aaronson has written, "Anyone perceived as the 'mainstream establishment' faces a near-insurmountable burden of proof, while anyone perceived as 'renegade' wins by default if they identify any hole whatsoever in mainstream understanding...

As with other kinds of authorities, there are reasonable criticisms to be made of academic physics. By some metrics, scientific productivity has slowed since the 1970s. String theory has not fulfilled physicists' early dreams that it would become the ultimate explanation of all forces and matter in our universe. The Large Hadron Collider, the world's largest particle accelerator, has delivered fewer breakthroughs than scientists expected when it turned on in 2010. But even reasonable points become hard to recognize when expressed in the ways YouTube incentivizes. Conspiracy physics videos with titles like "They Just Keep Lying" are full of sour sarcasm, outraged facial expressions and spooky music...

Leonard Susskind, director of the Stanford Institute for Theoretical Physics, says physicists need to be both more sober and more forceful when addressing the public. The limits of string theory should be acknowledged, he says, but the idea that progress has slowed isn't right. In the last few decades, he and other physicists have figured out how to make progress on the vast project of integrating general relativity and quantum mechanics, the century-old pillars of physics, into a single explanation of the universe.
The bitter attacks on leading physicists get a succinct summary in the article from Chris Williamson, a "Love Island" contestant turned podcast host. "This is like 'The Kardashians' for physicists — I love it."

The BBC reports that a million-year-old human skull found in China suggests that the human species "began to emerge at least half a million years earlier than we thought, researchers are claiming in a new study." It also shows that we co-existed with other sister species, including Neanderthals, for much longer than we've come to believe, they say.

The scientists claim their analysis "totally changes" our understanding of human evolution and, if correct, it would certainly rewrite a key early chapter in our history. But other experts in a field where disagreement over our emergence on the planet is rife, say that the new study's conclusions are plausible but far from certain.

The discovery, published in the leading scientific journal Science, shocked the research team, which included scientists from a university in China and the UK's Natural History Museum. "From the very beginning, when we got the result, we thought it was unbelievable. How could that be so deep into the past?" said Prof Xijun Ni of Fudan University, who co-led the analysis. "But we tested it again and again to test all the models, use all the methods, and we are now confident about the result, and we're actually very excited."

Long-time Slashdot reader theodp says America's Patent and Trademark Office (USPTO) has granted a patent to Tableau (Salesforce's visual analytics platform) — for a patent covering "Data Processing For Visualizing Hierarchical Data": "A provided data model may include a tree specification that declares parent-child relationships between objects in the data model. In response to a query associated with objects in the data model: employing the parent-child relationships to determine a tree that includes parent objects and child objects from the objects based on the parent-child relationships; determining a root object based on the query and the tree; traversing the tree from the root object to visit the child objects in the tree; determining partial results based on characteristics of the visited child objects such that the partial results are stored in an intermediate table; and providing a response to the query that includes values based on the intermediate table and the partial results."

A set of 15 simple drawings is provided to support the legal and tech gobbledygook of the invention claims. A person can have a manager, Tableau explains in Figures 5-6 of its accompanying drawings, and that manager can also manage and be managed by other people. Not only that, Tableau illustrates in Figures 7-10 that computers can be used to count how many people report to a manager. How does this magic work, you ask? Well, you "generate [a] tree" [Fig. 13] and "traverse a tree" [Fig. 15], Tableau explains. But wait, there's more — you can also display the people who report to a manager in multi-level or nested pie charts (aka Sunburst charts), Tableau demonstrates in Fig. 11.

Interestingly, Tableau released a "pre-Beta" Sunburst chart type in late April 2023 but yanked it at the end of June 2023 (others have long-supported Sunburst charts, including Plotly). So, do you think Tableau should be awarded a patent in 2025 on a concept that has roots in circa-1921 Sunburst charts and tree algorithms taught to first-year CS students in circa-1975 Data Structures courses?

"Researchers have modified a standard glue gun to 3D print a bone-like material directly onto fractures," reports LiveScience, "paving the way for its use in operating rooms." The device, which has so far been tested in rabbits, would be particularly useful for fixing irregularly shaped fractures during surgery, the researchers say.

"To my knowledge, there are virtually no previous examples of applying the technology directly as a bone substitute," study co-author Jung Seung Lee, a biomedical engineer at Sungkyunkwan University in South Korea, told Live Science in an email. "This makes the approach quite unique and sets it apart from conventional methods...." "Further studies in larger animal models are needed before the technology can be used on humans," the article points out.
