Published Did you know that physical activity can protect you from chronic pain?
(via sciencedaily.com) Original source Reserachers found that people who were more active in their free time had a lower chance of having various types of chronic pain 7-8 years later. For example, being just a little more active, such as going from light to moderate activity, was associated with a 5% lower risk of reporting some form of chronic pain later. For severe chronic pain in several places in the body, higher activity was associated with a 16% reduced risk. The researchers found that the ability to tolerate pain played a role in this apparent protective effect. That explains why being active could lower the risk of having severe chronic pain, whether or not it was widespread throughout the body.
Published Secrets of the naked mole-rat: new study reveals how their unique metabolism protects them from heart attacks
(via sciencedaily.com) Original source This unusual, subterranean mammal with extreme longevity shows genetic adaptations to low oxygen environments which could offer opportunities for advancing other areas of physiological and medical research in humans, including the development of novel therapeutic approaches.
Published Combination of the climate crisis and continued deforestation may result in significant damage to the animal world
(via sciencedaily.com) Original source A new study states that the combination of global warming and extreme heat events, alongside the continued expansion of deforestation in the world, may be devastating for many species of animals, especially those that know how to climb trees. As part of the study, the researchers focused on lizards and showed that following the effects of climate change, they will seek refuge from the hot ground by spending a lot of time on trees. However, due to human-related activities, such as deforestation, urbanization and the expansion of agricultural lands at the expense of natural lands, the availability of trees in the areas where the lizards live will decrease, and this may lead to the collapse of many populations.
Published Astronomers unveil strong magnetic fields spiraling at the edge of Milky Way's central black hole
(via sciencedaily.com) Original source A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view of the monster lurking at the heart of the Milky Way Galaxy has revealed a magnetic field structure strikingly similar to that of the black hole at the center of the M87 galaxy, suggesting that strong magnetic fields may be common to all black holes.
Published Distant 'space snowman' unlocks mystery of how some dormant deep space objects become 'ice bombs'
(via sciencedaily.com) Original source Researchers found that the double-lobed object, which is officially named Kuiper Belt Object 486958 Arrokoth and resembles a snowman, may have ancient ices stored deep within it from when the object first formed billions of years ago.
Published A decade of aphantasia research: what we've learned about people who can't visualize
(via sciencedaily.com) Original source People who can't visualize an image in their mind's eye are less likely to remember the details of important past personal events or to recognize faces, according to a review of nearly ten years of research. People who cannot bring to mind visual imagery are also less likely to experience imagery of other kinds, like imagining music, according to new research by the academic who first discovered the phenomenon.
Published Biologists uncover new species of tiger beetle: Eunota houstoniana
(via sciencedaily.com) Original source Evolutionary biologists have unearthed a new species of tiger beetle, deemed Eunota houstoniana, honoring the Houston region where it predominantly resides.
Published Milk on ice: Antarctic time capsule of whole milk powder sheds light on the enduring qualities--and evolution--of dairy products past and present
(via sciencedaily.com) Original source In a remarkable discovery, whole milk powder manufactured in New Zealand in 1907 and transported to Antarctica with explorers seeking the South Pole was unveiled after more than a century. The find has allowed dairy researchers to answer the question: Is the milk we enjoy today different from the milk consumed in previous generations? Now, a new comparative study has peered back in time to demonstrate that -- despite advancements in selective breeding and changes to farm practices -- milk of the past and milk today share more similarities than differences and are still crucial building blocks of human nutrition.
Published 'Cosmic cannibals' expel jets into space at 40 percent the speed of light
(via sciencedaily.com) Original source Astronomers have measured the speed of fast-moving jets in space, crucial to star formation and the distribution of elements needed for life. The jets of matter, expelled by stars deemed 'cosmic cannibals', were measured to travel at over one-third of the speed of light -- thanks to a groundbreaking new experiment.
Published Sleeping supermassive black holes awakened briefly by shredded stars
(via sciencedaily.com) Original source Astronomers have concluded that an obscure class of galaxies known as Compact Symmetric Objects, or CSOs, are not young as previously thought but rather lead relatively short lives.
Published Researchers find energy development and tree encroachment impact Wyoming pronghorn
(via sciencedaily.com) Original source While Wyoming is home to some of North America's most abundant populations of pronghorn that have largely been stable in recent years, a new analysis shows that many herds are experiencing long-term declines in fawn production.
Published Researchers show that introduced tardigrade proteins can slow metabolism in human cells
(via sciencedaily.com) Original source Tardigrade proteins are potential candidates in technologies centered on slowing the aging process and in long-term storage of human cells.
Published In paleontology, correct names are keys to accurate study
(via sciencedaily.com) Original source When the skeletal remains of a giant ground sloth were first unearthed in 1796, the discovery marked one of the earliest paleontological finds in American history.
Published Beethoven's genes reveal low predisposition for beat synchronization
(via sciencedaily.com) Original source Ludwig van Beethoven, one of the most celebrated musicians in human history, has a rather low genetic predisposition for beat synchronization, according to a new study.
Published Micro-Lisa! Making a mark with novel nano-scale laser writing
(via sciencedaily.com) Original source High-power lasers are often used to modify polymer surfaces to make high-tech biomedical products, electronics and data storage components. Now researchers have discovered a light-responsive, inexpensive sulfur-derived polymer is receptive to low power, visible light lasers -- promising a more affordable and safer production method in nanotech, chemical science and patterning surfaces in biological applications.

(via sciencedaily.com) Original source An orange dwarf star has yielded the tiniest 'starquakes' ever recorded, measured by an international team of scientists.
Published Scientists on the hunt for evidence of quantum gravity's existence at the South Pole
(via sciencedaily.com) Original source An Antarctic large-scale experiment is striving to find out if gravity also exists at the quantum level. An extraordinary particle able to travel undisturbed through space seems to hold the answer.
Published New roadmap to prevent pandemics centers on protecting biodiversity
(via sciencedaily.com) Original source An international team of 25 scientists has proposed a roadmap for how to prevent the next pandemic by conserving natural areas and promoting biodiversity, thereby providing animals with enough food, safe havens and distance to limit contact and the transfer of pathogens to humans.
