Bhavik Nagda: Delving into the deployment of new technologies
“We need more technologists in the room while policies are formulated,” says the MIT senior.
Aspiring physician explores the many levels of human health
During her time at MIT, senior Ayesha Ng’s interests have expanded from cellular biology to the social systems that shape public health.
Using machine learning to track the pandemic’s impact on mental health
Textual analysis of social media posts finds users’ anxiety and suicide-risk levels are rising, among other negative trends.
Scientists identify specific brain region and circuits controlling attention
Norepinephrine-producing neurons in the locus coeruleus produce attention focus, impulse control via two distinct connections to prefrontal cortex.
How a worm may yield insights into the gut-brain relationship
Gurrein Madan, brain and cognitive sciences graduate student and MathWorks Fellow, studies gut–brain signaling with implications for human health.
Study helps explain why motivation to learn declines with age
Research on mice suggests aging affects a brain circuit critical for learning to make some types of decisions.
Emery Brown wins Swartz Prize for Theoretical and Computational Neuroscience

Scientists uncover new clues about Parkinson’s disease
Tool developed at MIT simultaneously measures chemical and electrical brain signals, revealing unexpectedly complex relationship between brain signals.
Alzheimer’s risk gene disrupts endocytosis, but another disease-linked gene could help
Astrocytes with the APOE4 gene variant show deficits of a key cellular function, but overexpressing the gene PICALM overcame the defect.
Neuroscientists discover a molecular mechanism that allows memories to form
Modifications to chromosomes in “engram” neurons control the encoding and retrieval of memories.
How we make moral decisions
In some situations, asking “what if everyone did that?” is a common strategy for judging whether an action is right or wrong.
Live imaging method brings structure to mapping brain function
Scientists distinguish brain regions based on what they do, but now have a new way to overlay information about how they are built.
