The Mind

Conceptual art showing brain with two targeted areas being affected by ultrasound waves. Using the tools of sonogenetics, focused ultrasound beams can deliver drugs or gene therapy to targets in the brain with millimeter precision.

Sounding out the brain

Ultrasound isn’t just for images. Sonogenetics and other promising technologies let researchers use focused sound waves to control genes and entire cells deep in the tissues of living animals, without surgery.

Illustration of the brain’s information storage system as a brain-shaped set of filling cabinets that store memories. Some pieces of paper are falling out of the cabinets, representing how we forget memories. Emerging views see forgetting as an active process of an efficient brain designed to make good decisions.

Why forgetting may make your mind more efficient

Evidence builds for ways that the brain actively erases memories

Reaching out to touch virtual reality

New technologies mean we won’t just see and hear digital information. We’ll also feel it.

Bypassing paralysis

By decoding brain activity with electrical implants, computers can help disabled people move a robotic arm — or their own

A long-overlooked brain region may be key to complex thought

The thalamus has traditionally been viewed just as the brain’s sensory relay station. But it may also play an important role in higher-level cognition, MIT’s Michael Halassa explains in a Q&A.

Top 10 secrets about stress and health

The strain of life — from everyday conflicts to major losses — can stretch our well-being to the breaking point. Here’s what scientists know, and still don’t know, about the stress-illness connection.

Fighting urban violence, one empty lot at a time

Could cleaning up neighborhoods make cities safer? Researchers are looking at novel, inexpensive solutions to crime that everyone can agree on.

A woman holds a conductor's baton in front of red neon sculptures of various musical instruments. Human response to music has deep evolutionary roots and seems hard-wired in the brain, says cognitive psychologist Daniel Levitin in this Q&A.

The music moves us — but how?

The author of This Is Your Brain on Music talks about the very human ways the mind and body keep the beat.

Immigration isn’t linked to higher crime rates — but not everyone can believe it

Criminologist Charis Kubrin has spent more than a decade researching the effects of immigration on law and order. She’s finding that it takes more than data to make her case.

Trendy office layouts. Performance reviews that crush morale. There’s plenty of evidence on how to get the best out of workers, but businesses often ignore it.

Bad bosses: Dealing with abusive supervisors

From the boardroom to the basketball court, some managers rely on berating and bullying employees. Researchers have learned one thing: It doesn’t work.

Countermarketing succeeds by exposing the motives behind the advertising of unhealthy products. It worked for teen smoking — could it do the same for junk food?

Feeling the pressure

How we want to be perceived influences how we act, and that presents persuasion opportunities. But the social factors involved are not easy to unravel.
