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 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 ...

Scientists have found a way to see ultrafast molecular interactions inside liquids using an extreme laser technique once thought impossible for fluids. When they mixed nearly identical chemicals, one combination behaved strangely--producing less ...

Tiny bits of Earth's atmosphere have been drifting to the moon for billions of years, guided by Earth's magnetic field. Rather than blocking particles, the magnetic field can funnel them along invisible lines that sometimes stretch all the way to the ...
