For the first time, astronomers have captured radio signals from a rare exploding star, exposing what happened in the years leading up to its death. The radio waves reveal that the star violently shed huge amounts of material shortly before it ...

What looked like a pearl necklace on a tiny spider turned out to be parasitic mite larvae. Scientists identified the mites as a new species, marking the first record of its family in Brazil. The larvae attach to juvenile spiders and feed on lymph ...

A sweeping scientific review highlights wild blueberries as a standout food for cardiometabolic health. The strongest evidence shows improvements in blood vessel function, with encouraging signs for blood pressure, cholesterol, blood sugar, gut ...

A common parasite long thought to lie dormant is actually much more active and complex. Researchers found that Toxoplasma gondii cysts contain multiple parasite subtypes, not just one sleeping form. Some are primed to reactivate and cause disease, .. ...

Researchers have discovered a biological switch that explains why movement keeps bones strong. The protein senses physical activity and pushes bone marrow stem cells to build bone instead of storing fat, slowing age-related bone loss. By targeting .. ...

Asthma may not be driven by the molecules scientists have blamed for decades. Researchers have identified "pseudo leukotrienes," inflammation-triggering compounds formed by uncontrolled free-radical reactions rather than normal enzymes. These ...

A long-term study found that while a ketogenic diet prevented weight gain, it also triggered major metabolic problems. Mice developed fatty liver disease, abnormal blood fats, and an impaired ability to control blood sugar--especially after ...

Findings could create new opportunities to treat and study neurodegenerative diseasesScientists discovered that sugar metabolism plays a surprising role in whether injured neurons collapse or cling to life. By activating internal protective programs, ...

Quantum technology has reached a turning point, echoing the early days of modern computing. Researchers say functional quantum systems now exist, but scaling them into truly powerful machines will require major advances in engineering and ...

Bright white rocks spotted by NASA's Perseverance rover are rewriting what we thought we knew about ancient Mars. These aluminum-rich clays, called kaolinite, usually form on Earth only after millions of years of heavy rainfall in warm, humid ...
