Nearly all women in STEM graduate programs report feeling like impostors, despite strong evidence of success. This mindset leads many to dismiss their achievements as luck and fear being "found out." Research links impostorism to worse mental health, ...

The idea that we make over 200 unconscious food choices a day has been repeated for years, but new research shows the number is more illusion than insight. The famous figure comes from a counting method that unintentionally exaggerates how many ...

New research shows gut bacteria can directly influence how the brain develops and functions. When scientists transferred microbes from different primates into mice, the animals' brains began to resemble those of the original host species. Microbes .. ...

A protein once thought to simply help cancer cells avoid death turns out to do much more. MCL1 actively drives cancer metabolism by controlling the powerful mTOR growth pathway, tying survival and energy use together. This insight explains why MCL1 . ...

A meltwater lake that formed in the mid-1990s on Greenland's 79°N Glacier has been draining in sudden, dramatic bursts through cracks and vertical ice shafts. These events have accelerated in recent years, creating strange triangular fracture ...

A large study has revealed that dozens of widely used chemicals can damage beneficial gut bacteria. Many of these substances, found in pesticides and everyday industrial products, were never thought to affect living organisms at all. When gut ...

A new CRISPR breakthrough shows scientists can turn genes back on without cutting DNA, by removing chemical tags that act like molecular anchors. The work confirms these tags actively silence genes, settling a long-running scientific debate. This ...

CO2 can stimulate plant growth, but only when enough nitrogen is available--and that key ingredient has been seriously miscalculated. A new study finds that natural nitrogen fixation has been overestimated by about 50 percent in major climate models. ...

Researchers have developed experimental compounds that make cells burn more calories by subtly tweaking how mitochondria produce energy. Older versions of these chemicals were once used for weight loss--but were banned for being deadly. The new ...

One of the most complete human ancestor fossils ever found may belong to an entirely new species, according to an international research team. The famous "Little Foot" skeleton from South Africa has long been debated, but new analysis suggests it ...
