Celebrating worm science
Time and again, an unassuming roundworm has illuminated aspects of biology with major consequences for human health.

Prefrontal cortex reaches back into the brain to shape how other regions function
Research illustrates how areas within the brain’s executive control center tailor messages in specific circuits with other brain regions to influence them with information about behavior and feelings.
RNA editing study finds many ways for neurons to diversify
Tracking how fruit fly motor neurons edit their RNA, neurobiologists cataloged hundreds of target sites and varying editing rates, finding many edits altered communication- and function-related proteins.
School of Science welcomed new faculty in 2024
Eleven new professors join the departments of Biology; Brain and Cognitive Sciences; Earth, Atmospheric and Planetary Sciences; Mathematics; and Physics.
MIT study shows how vision can be rebooted in adults with amblyopia
Temporarily anesthetizing the retina briefly reverts the activity of the visual system to that observed in early development and enables growth of responses to the amblyopic (“lazy”) eye.
Too sick to socialize: How the brain and immune system promote staying in bed
MIT researchers discover how an immune system molecule triggers neurons to shut down social behavior in mice modeling infection.
Symposium examines the neural circuits that keep us alive and well
Seven speakers from around the country convened at MIT to describe some of the latest research on the neural mechanisms that we need to survive.
Study suggests 40Hz sensory stimulation may benefit some Alzheimer’s patients for years
Five volunteers received 40Hz stimulation for around two years after an early-stage clinical study. Those with late-onset Alzheimer’s performed better on assessments than Alzheimer’s patients outside the trial.
MIT researchers invent new human brain model to enable disease research, drug discovery
Cultured from induced pluripotent stem cells, “miBrains” integrate all major brain cell types and model brain structures, cellular interactions, activity, and pathological features.
This is your brain without sleep
New research shows attention lapses due to sleep deprivation coincide with a flushing of fluid from the brain — a process that normally occurs during sleep.
Neural activity helps circuit connections mature into optimal signal transmitters
Scientists identified how circuit connections in fruit flies tune to the right size and degree of signal transmission capability. Understanding this could lead to a way to tweak abnormal signal transmission in certain disorders.
Immune-informed brain aging research offers new treatment possibilities, speakers say
Speakers at MIT’s Aging Brain Initiative symposium described how immune system factors during aging contribute to Alzheimer’s, Parkinson’s and other conditions. The field is leveraging that knowledge to develop new therapies.
Study finds key role for non-neural brain cells in processing vision
MIT researchers employed a novel application of tools and analysis to show that astrocytes ensure neural information processing by maintaining ambient levels of the neurotransmitter chemical GABA.
How the brain splits up vision without you even noticing
As an object moves across your field of view, the brain seamlessly hands off visual processing from one hemisphere to the other like cell phone towers or relay racers do, a new MIT study shows.
Study explains how a rare gene variant contributes to Alzheimer’s disease
Lipid metabolism and cell membrane function can be disrupted in the neurons of people who carry rare variants of ABCA7.
