Motor neurons don’t just move muscles. They may direct that motion too
A fruit fly study shows motor neurons do more than relay commands: They send signals back to the brain and organize movement sequences.

A photographic memory is wishful thinking
In fiction, photographic memories crack the case or save the day. But our brains can’t hold on to everything — and that’s a good thing.

Estrogen therapy is linked to fewer signs of Alzheimer’s in the brain
Estrogen-only menopause therapy in older women was linked to less Alzheimer’s brain pathology at autopsy but may not prevent the disease.

Whether lefty or righty, practice makes the difference
Researchers looking for the origins of left-right dominance in the brain found no innately better motor skills on either side.

Brains break and repair DNA to grow
Newborn mice neurons can snap both DNA strands to migrate, then repair the breaks within a day. The process may be a normal part of brain development.

The ‘little brain’ may give the aging mind a big boost
Most known for its role in movement, the cerebellum could compensate for flagging mental functions elsewhere in the brain.

A blood test for dementia may tell you if you have more than one type
AI helped researchers develop an experimental blood test that might let doctors diagnose overlapping dementias.

A tiny part of your brain may still listen under anesthesia
Tones, oddball sounds and words can spark brain cell responses, hinting at nuanced processing without consciousness.

Can DEET attract mosquitoes? A lab study offers clues
Lab experiments suggest mosquitoes can smell DEET and learn to associate it with food, but it’s unclear whether that happens in the wild.
