Sparkling water is often seen as a simple, healthy drink--but could it also help with weight loss? New research suggests it may slightly boost how the body processes blood sugar and energy. However, the effect is very small, meaning it's no ...
A hormone called FGF21 can reverse obesity in mice by activating a newly identified brain circuit tied to metabolism. Surprisingly, it works in the hindbrain--the same region targeted by GLP-1 drugs like Ozempic and Wegovy--but through a completely . ...
Researchers have found a way to make cancer-killing immune cells more powerful and precise. By adding specific signaling components, they boosted the cells' readiness to attack tumors. Surprisingly, briefly suppressing the cells with a drug before .. ...
Scientists have discovered that a protein linked to cell death is secretly driving the aging of blood stem cells in a completely different way. Instead of killing the cells, it damages their mitochondria, sapping their energy and weakening the immune ...
A rogue set of "zombie" immune cells may be driving aging and fatty liver disease by flooding tissues with inflammation. Researchers found these cells accumulate with age and high cholesterol--and can make up most of the liver's immune cells in older ...
The ozone layer has been on track to recover thanks to the Montreal Protocol--but a loophole may be holding it back. Chemicals still permitted for industrial use are leaking into the atmosphere at higher rates than expected. Scientists now estimate . ...
Researchers have discovered lithium hidden in pyrite within ancient shale rocks--an unexpected find that could reshape how we source this critical battery material. It raises the possibility of extracting lithium from existing waste, reducing the ...
A massive, nearly 20-year study tracking over 650,000 Americans with irritable bowel syndrome is raising new questions about the long-term safety of common treatments. Researchers found that some widely used medications--including antidepressants and ...
Scientists have discovered that methane in the open ocean is produced by microbes under nutrient-poor conditions, solving a long-standing mystery. As warming oceans reduce nutrient mixing, these methane-producing microbes may thrive. This could lead ...
New research suggests that aiming for a lower blood pressure target may deliver bigger heart health benefits than previously thought. Using large datasets and simulation models, scientists found that keeping systolic blood pressure below 120 mm Hg .. ...
