Researchers uncovered how shifting levels of a brain protein called KCC2 can reshape the way cues become linked with rewards, sometimes making habits form more quickly or more powerfully than expected. When this protein drops, dopamine neurons fire . ...

Obesity accelerates the rise of Alzheimer's-related blood biomarkers far more rapidly than previously recognized. Long-term imaging and plasma data show that obese individuals experience much faster increases in proteins linked to neurodegeneration . ...

Researchers have uncovered surprising evidence that the deep ocean's carbon-fixing engine works very differently than long assumed. While ammonia-oxidizing archaea were thought to dominate carbon fixation in the sunless depths, experiments show that ...

Uranus and Neptune may not be the icy worlds we've long imagined. A new Swiss-led study uses innovative hybrid modeling to reveal that these planets could just as easily be dominated by rock as by water-rich ices. The findings also help explain their ...

Researchers discovered that a long-misunderstood protein plays a key role in helping chromosomes latch onto the right "tracks" during cell division. Instead of acting like a motor, it works more like a stabilizer that sets everything up correctly ...

A Virginia Tech study shows that ultra-processed foods may influence adolescents differently from slightly older young adults. Participants aged 18 to 21 ate more at a buffet and snacked even when not hungry after two weeks on an ultra-processed diet ...

New research reveals that Earth's solid inner core is actually in a superionic state, where carbon atoms flow freely through a solid iron lattice. This unusual behavior makes the core soft, matching seismic observations that have puzzled scientists . ...

New research is challenging one of medicine's oldest assumptions: that cancer must be attacked to be cured. By treating glioblastoma patients with a simple combination of resveratrol and copper, the researchers found dramatic reductions in tumor ...

Astronomers using the James Webb Space Telescope have captured dramatic helium streams pouring off the super-puff exoplanet WASP-107b, revealing a world with an enormously inflated, weakly bound atmosphere under intense stellar heat. The detection of ...

Humans don't just recognize each other's voices--our brains also light up for the calls of chimpanzees, hinting at ancient communication roots shared with our closest primate relatives. Researchers found a specialized region in the auditory cortex .. ...
