Uncovering the mechanism of our oldest anesthetic

Uncovering the mechanism of our oldest anesthetic

Nitrous oxide, commonly known as “laughing gas,” has been used in anesthesiology practice since the 1800s, but the way it works to create altered states is not well understood. In a study published this week in Clinical Neurophysiology, MIT researchers reveal some key...
Better batteries, half price

Better batteries, half price

An advanced manufacturing approach for lithium-ion batteries, developed by researchers at MIT and at a spinoff company called 24M, promises to significantly slash the cost of the most widely used type of rechargeable batteries while also improving their performance...
Recalling happier memories can reverse depression

Recalling happier memories can reverse depression

MIT neuroscientists have shown that they can cure the symptoms of depression in mice by artificially reactivating happy memories that were formed before the onset of depression. The findings, described in the June 18 issue of Nature, offer a possible explanation for...
Pneumonia found to harm DNA in lung cells

Pneumonia found to harm DNA in lung cells

A bacterium that is the most common cause of pneumonia — a leading cause of death worldwide — can damage DNA in lung cells, a new study has shown. Researchers from the Singapore-MIT Alliance for Research and Technology (SMART) demonstrated that hydrogen peroxide...
Breaking down social networks in a city

Breaking down social networks in a city

New research finds urban social networks are not determined geographically, but socially. Until now, studies of human interactions through mobile communication and social media have always been conducted at the country scale — using broad strokes to produce...
DNA breakage underlies both learning, age-related damage

DNA breakage underlies both learning, age-related damage

The process that allows our brains to learn and generate new memories also leads to degeneration as we age, according to a new study by researchers at MIT. The finding, reported in a paper published today in the journal Cell, could ultimately help researchers develop...
