Ice age humans in China crafted surprisingly advanced stone tools 146,000 years ago

Scientists in China discovered that ancient humans were making surprisingly advanced stone tools during a harsh ice age 146,000 years ago. The tools, created by Homo juluensis, show careful planning and complex thinking rather than simple stone-chipping. Researchers dated the site using tiny calcite crystals inside animal bones, revealing the tools are much older than expected. The discovery challenges the idea that human creativity only thrives in easy, prosperous times. from Latest Science News -- ScienceDaily https://ift.tt/eMlLfpj

A common constipation drug shows surprising power to protect kidneys

A common constipation drug may have unexpectedly unlocked a new way to slow chronic kidney disease — a condition that affects millions and often leads to dialysis. In a clinical trial involving 150 patients, researchers found that lubiprostone, a medication normally used to treat constipation, helped preserve kidney function in people with moderate CKD. Scientists traced the effect to changes in gut bacteria that boosted production of spermidine, a compound linked to healthier mitochondria and reduced kidney damage. from Latest Science News -- ScienceDaily https://ift.tt/U5Q8Gde

Scientists discover a new way to prevent gum disease without killing good bacteria

Scientists have uncovered a surprising way to influence the bacteria living in our mouths — not by killing them, but by interrupting how they “talk” to each other. Researchers found that dental plaque bacteria use chemical signals to coordinate growth, and by blocking those signals, they were able to encourage healthier bacteria while reducing disease-linked microbes tied to gum disease. Even more intriguing, the bacterial conversations changed depending on oxygen levels above and below the gums, revealing an entirely new layer of complexity inside the mouth. from Latest Science News -- ScienceDaily https://ift.tt/xFR02CV

Scientists discover why Ozempic works better for some people

Some people taking Ozempic-like diabetes drugs may be getting dramatically better results for a surprising reason: why they overeat in the first place. A year-long study in Japan found that people who tend to eat because tempting food looks or smells irresistible were much more likely to lose weight and improve blood sugar levels on GLP-1 medications. But people who eat mainly in response to stress, sadness, or emotional struggles didn’t see the same long-term benefits. from Latest Science News -- ScienceDaily https://ift.tt/UFdNsOh
