As the early-2000s bop goes, you would not believe your eyes, if 10 million fireflies lit up the world as I fell asleep. While 10 million may not be the exact number of the summer staple lighting up the sky, several

By genetically forcing cells to eliminate their mitochondria, researchers at UT Southwestern uncovered surprising insights into how these organelles influence development, gene regulation, and even evolution. Their work reveals that cells can temporarily survive without mitochondria and that mitochondrial-nuclear interactions may subtly shape traits like brain development across species.  Credit: Shutterstock New method developed by

Neanderthals from two nearby caves cut meat in surprisingly different ways—revealing what might be the earliest signs of culinary culture. Credit: Shutterstock Bone cut-marks suggest Neanderthals had distinct food traditions—possibly even early “family recipes.” A new study from the Hebrew University of Jerusalem has uncovered surprising clues about how Neanderthals prepared their food. Researchers found

A fossil sample. Credit: Grace DuVal Protein remnants in fossil enamel reveal new ways to study evolution. These molecules stretch our view of molecular preservation far into the past. Proteins naturally break down over time, which makes it difficult to trace their origins and preserve their biological history. However, a recent study has revealed the

Trump’s leg condition may be more dangerous and more common than you think. Shutterstock After former President Donald Trump was diagnosed with Chronic Venous Insufficiency (CVI), attention has turned to this underrecognized but serious vein condition. CVI causes blood to pool in the legs due to faulty valves in the veins, leading to swelling, fatigue

A new NHS study found that music therapy can be more effective than medication in soothing dementia patients in some cases, offering a gentler, more human approach to care.

After a long wait, astronomers have finally seen the stellar companion of the famous star Betelgeuse. This companion star orbits Betelgeuse in an incredibly tight orbit, which could explain one of Betelgeuse’s longstanding mysteries. The star is doomed, however, and the team behind this discovery predicts that Betelgeuse will cannibalize it in a few thousand
