Walking on Two Legs May Have Evolved in Trees, Not on the Ground   2025-08-03 11:36:24 +00:00 New research on chimpanzees living in the open woodlands of Tanzania suggests that the story of how humans learned to walk on two legs may need a rewrite. Despite their dry, savannah-mosaic environment, these chimpanzees still climb trees regularly to forage—especially when the food is abundant and harder to reach. Their behavior hints that bipedalism [...] Read more...   Deep-Sea DNA Breakthrough Reveals Hidden Oceanic “Superhighway”   2025-08-03 11:11:20 +00:00 A world-first study conducted by the Museums Victoria Research Institute has discovered that marine life in the cold, dark, and pressurized depths of the ocean is far more globally interconnected than scientists had previously believed. A groundbreaking study led by the Museums Victoria Research Institute has uncovered a surprising truth about the deep sea: marine [...] Read more...   Scientists Have Discovered a “Sixth Sense” That Links the Gut and Brain in Real Time   2025-08-03 10:46:08 +00:00 A groundbreaking discovery from Duke University School of Medicine reveals a direct connection between the microbiome and the brain, shedding new light on the regulation of behavior and appetite. In a major scientific development, researchers have identified a new way the brain and gut interact, unveiling what they describe as a “neurobiotic sense.” This previously [...] Read more...   X-Ray Spacecraft Uncovers Missing Sulfur in the Milky Way   2025-08-03 04:31:03 +00:00 A groundbreaking X-ray study reveals how sulfur changes form in space, offering new insight into the hidden chemistry of the Milky Way. A global team of scientists has made a groundbreaking measurement of elemental sulfur distributed throughout space, using observations from the XRISM (X-ray Imaging and Spectroscopy Mission) spacecraft, which is led by Japan. By [...] Read more...   Solving a 13-Billion-Year-Old Mystery: Scientists Recreate the Universe’s First Chemical Reaction   2025-08-03 03:56:01 +00:00 Researchers have uncovered new insights into the reaction pathways of the universe’s first molecule. Shortly after the Big Bang, which took place around 13.8 billion years ago, the universe was a seething, dense expanse of extreme heat. In just a matter of seconds, it began to cool enough for the first atomic particles to come [...] Read more...   New Research Reveals Living by the Ocean Could Add a Year to Your Life   2025-08-02 23:02:16 +00:00 Oceans are associated with benefits not observed near inland waterways. Living near the ocean may be associated with a longer lifespan, but a similar benefit does not appear to extend to people living in cities beside rivers or lakes, according to a new study. Researchers at The Ohio State University examined population data from over [...] Read more...   Scientists Built a Test That Predicts Obesity. The Results Are Wild   2025-08-02 22:37:21 +00:00 What if we could foresee obesity decades before it happens—and actually prevent it? Scientists have developed a powerful genetic test that predicts whether a child as young as five is likely to become obese as an adult. Using data from over five million people, the tool—called a polygenic risk score—outperforms previous methods by a wide [...] Read more...   Just 15 Minutes of Fast Walking a Day Could Save Your Life, New Study Finds   2025-08-02 22:12:17 +00:00 A study highlights the health benefits of walking among an underrepresented group of low-income and Black individuals. Walking regularly is known to offer numerous health benefits, but most studies on the topic have centered around White individuals from middle- to high-income backgrounds. A new analysis is now helping to fill that gap. Drawing on data [...] Read more...   Study Reveals Two Simple Financial Habits That Significantly Boost Mental Health   2025-08-02 15:59:02 +00:00 New research shows that regularly saving money and paying off debt isn’t just good for your wallet—it’s a powerful way to boost mental health and resilience, no matter your income. Finance experts at the University of South Australia have found that maintaining consistent savings and paying off credit card debt on time can play a [...] Read more...   This Simple 10-Minute Trick Keeps Mangoes Fresh for Weeks   2025-08-02 15:24:16 +00:00 Mangoes might soon last far longer on shelves and in fridges, thanks to a breakthrough from Edith Cowan University researchers. By dipping the fruit in ozonated water for just 10 minutes, scientists extended the cold storage life of mangoes up to 28 days while drastically reducing spoilage caused by chilling injury. Ozonated Water Gives Mangoes [...] Read more...   Neuroscience Just Proved Optimists Are on the Same Wavelength   2025-08-02 09:48:11 +00:00 Optimists may be more alike than we thought—right down to their brainwaves. A new study shows they imagine the future in surprisingly similar ways, while pessimists each think differently. This brain-sync could explain why optimists connect more easily. The Social Lives of Optimists People who are more optimistic often report greater satisfaction with their social [...] Read more...   AI Pushes Imaging to the Absolute Brink of Physical Limits   2025-08-02 09:23:02 +00:00 How precisely can an object be measured when all you have is a blurred image? At TU Wien, researchers have pushed the boundaries of possibility using artificial intelligence. No image can ever be perfectly sharp. For over 150 years, scientists have understood that even the most advanced microscopes and cameras are subject to fundamental resolution [...] Read more...   The “Electron Shower” That’s Revolutionizing Microchip Manufacturing   2025-08-02 08:58:40 +00:00 Scientists have cracked a long-standing challenge in thin-film electronics. We are surrounded by electronic devices to such an extent that we often overlook the intricate technology behind them. A simple action like picking up a smartphone rarely prompts us to consider the complexity built into it. Inside, hundreds of miniature components operate in harmony, each [...] Read more...   Why Plant-Based Eggs Are Finally Getting the Spotlight   2025-08-02 05:19:26 +00:00 Consumers may be more open to plant-based eggs when they’re introduced as familiar ingredients rather than standalone substitutes, pointing to a strategic way forward for adoption. As interest in plant-based meat and dairy continues to rise, products like vegan burgers, nuggets, and beverages have taken the spotlight as promising sustainable protein options. However, plant-based eggs [...] Read more...   Scientists Debunk Popular Myth: Eating Sugar Doesn’t Make You Crave It More   2025-08-02 03:59:58 +00:00 A new study challenges the widely held belief that eating sweet foods increases your craving for them.
