This brain circuit may explain fluctuating sensations—and autism

Sometimes a gentle touch feels sharp and distinct, other times it fades into the background. This inconsistency isn’t just mood—it’s biology. Scientists found that the thalamus doesn’t just relay sensory signals—it fine-tunes how the brain responds to them, effectively changing what we feel. A hidden receptor in the cortex seems to prime neurons, making them more sensitive to touch.

Is that really ADHD? Why flawed trials may be misleading millions

Researchers reviewing nearly 300 top-tier ADHD drug trials found that half skipped the rigorous, expert-led evaluations needed to rule out other conditions like depression or schizophrenia. With diagnoses often made by unqualified staff—or even by computer—many participants may not have actually had ADHD, casting doubt on study outcomes that shape treatment guidelines.

Are lefties really more creative? 100 years of data say no

A sweeping review of more than a century’s research upends the popular notion that left-handers are naturally more creative. Cornell psychologist Daniel Casasanto’s team sifted nearly a thousand studies, ultimately finding no consistent advantage for lefties on standard divergent-thinking tests—and even a slight edge for right-handers in some. The myth appears to thrive on coincidence: left-handedness is rare and so is creative genius, plus lefties’ overrepresentation in art and music gets cherry-picked while other professions are ignored.

Citizen scientists spot rare exploding star in real-time

Citizen scientists using the Kilonova Seekers platform spotted a stellar flash 2,500 times brighter than before, allowing astronomers to identify the exploding cataclysmic variable GOTO0650 within hours. Swift community follow-up captured X-ray, UV, and amateur telescope data, revealing the star’s rare “period-bouncer” stage.

Scientists just mapped how the body rejects pig organs—and how to stop it

Scientists have achieved an unprecedented look into how the human immune system attacks a transplanted pig kidney, using spatial molecular imaging to map immune activity down to the cellular level. They discovered early signs of rejection within 10 days and pinpointed key immune players—like macrophages—driving the response. Even more exciting: when targeted therapies were applied, the immune assault weakened. As U.S. clinical trials of pig kidney transplants begin, this breakthrough offers hope for overcoming the immune barrier that has long stood in the way of xenotransplantation.
