Seeing a potentially infectious person might kickstart the body's immune system, according to a new study.

The Mere Sight of Someone Sick Triggers an Immune Response, Study Suggests

Researchers equipped study participants with virtual reality headsets and observed how their brains and immune systems reacted to avatars with signs of illness

A new study reveals that optimists show similar brain activity when they think about the future, while pessimists' neural patterns are more individual.

Optimists Really Are on the ‘Same Wavelength’ When They Think About the Future, New Study of Brain Activity Suggests

As the research participants thought about future scenarios, optimists displayed similar neural patterns, but pessimists showed more individualized brain activity

Girls' ADHD symptoms are often mistakenly attributed to other issues, like anxiety or depression, and it may take until adulthood for women to be accurately diagnosed.

The Future of Mental Health

Why Are So Many More Women Being Diagnosed With ADHD?

Experts once thought ADHD was something only boys experienced. The research is finally starting to catch up with reality

The patient looks through measuring goggles at a series of markers on a grid. 

Can a Medical Device Restore Your Balance?

Nearly two million people worldwide have lost the simple ability to feel steady. Now researchers have developed an experimental medical implant that promises to restore the sensory machinery responsible for balance

Taking a short, deep nap may help you have an "a-ha" moment after you wake up.

Need to Solve a Problem? Try Taking a Deep Power Nap for an ‘Aha’ Moment, Research Suggests

A new study finds that entering N2 sleep—a deep phase of non-rapid eye movement sleep—may help lead to more “eureka” breakthroughs

Researchers developed a wearable device to monitor participants' breathing.

The Way You Breathe Is Unique to You, Like a Fingerprint, New Study Suggests

Researchers could identify people with almost 97 percent accuracy based on 24 hours of their recorded breathing patterns, and they also found links to a person’s mental and physical condition

Psychiatric neurosurgery, originally known as psychosurgery, involves operating on the brain to alter its function.

What Does the Future Hold for Psychiatric Brain Surgery?

For some patients, removing brain tissue can help treat OCD and other disorders. But ethical concerns remain

Composer Alvin Lucier in 1986

Art Meets Science

Artificial ‘Brain’ Aims to Allow Composer to Keep Making Music Three Years After His Death

Before dying in 2021, Alvin Lucier donated blood for “Revivification,” an installation that generates sound in response to neural signals

Human perception of color is regulated by three types of cone cells in the eye. By artificially stimulating just one type with a laser, researchers and study participants experienced a new color they call "olo."

Scientists Say They’ve Discovered a New Color—an ‘Unprecedented’ Hue Only Ever Seen by Five People

The color, dubbed olo, is described as an intensely saturated teal. Researchers say it might have applications in understanding color blindness

A cell culture plate with pluripotent stem cells, which can differentiate into any kind of cell in the body.

Stem Cell Therapies Could Treat Parkinson’s Disease by Rebuilding Lost Circuitry in the Brain, Studies Suggest

Two small clinical trials tested the safety of injecting stem cells into the brains of Parkinson’s patients and found no adverse effects

A subset of more than 1,000 neurons, representing just a snapshot of the complexity mapped within a cubic millimeter of mouse brain tissue

In a World First, Researchers Mapped Part of a Mouse’s Brain in Incredible Detail. It’s a Leap Forward for Neuroscience

The 3D brain map includes more than 200,000 cells, 523 million synapses and over two miles of axons, representing the most detailed wiring diagram of a piece of mammal brain ever constructed

Many teens have shared videos on social media showing their use of nitrous oxide, or laughing gas, which is sold in small metal canisters.

The Long, Strange History of Nitrous Oxide, a Popular Drug Users Have Been Inhaling for Hundreds of Years

Galaxy Gas has brought the drug back into the spotlight, and scientists are raising alarms about its health risks

Researchers connect stroke survivor Ann Johnson's brain implant to the experimental computer, which will allow her to speak by thinking words.

Enhanced Brain Implant Translates Stroke Survivor’s Thoughts Into Nearly Instant Speech Using Artificial Intelligence

The system harnesses technology similar to that of devices like Alexa and Siri, according to the researchers, and improves on a previous model

More than a third of endometriosis patients are misdiagnosed with mental health conditions.

For Some Women With Serious Physical Ailments, Mental Illness Has Become a Scapegoat Diagnosis

Patients with difficult-to-diagnose conditions like endometriosis are often sent home with diagnoses like anxiety or bipolar disorder

Budgerigars are the only animals known so far to have language-producing centers of neurons akin to those in humans, according to new research.

Can Parrot Brains Teach Us About Human Speech? Study Finds Budgies Have Language-Producing Regions That Resemble Our Own

The parakeets commonly kept as pets could offer fresh clues about vocal learning and potential treatments for speech disorders

Cells producing the NOVA1 protein are shown in green in the brain of a mouse. A specific variant of this protein is unique to humans, and researchers suggest it is linked to spoken language development.

Scientists Identify a Gene Linked to Spoken Language, and It Makes Lab Mice Squeak Differently

A new study suggests the unique human version of the NOVA1 protein developed after our ancestors split from Neanderthals on the evolutionary tree, and it might have given us a competitive edge over our relatives

Mice have an instinctive reaction to hide when the shadow of a bird passes over. In a new study, scientists taught the rodents to overcome that fear.

How Can the Brain Overcome Fear? New Study of Mice Offers Clues to PTSD and Anxiety Treatment

Researchers identified two brain areas in mice that helped the animals learn to suppress their instinctive fears of predators

Nyota, a 25-year-old male bonobo at Ape Initiative in Iowa, participated in the study.

When Bonobos Know What You Don’t, They’ll Tell You. It’s a Sign of a Cognitive Ability Called ‘Theory of Mind’

A first-of-its-kind study suggests bonobos, like humans, can understand someone else’s lack of knowledge—and adjust their actions accordingly

Researchers found higher levels of microplastics in brain tissue than in liver and kidney tissue.

The Human Brain May Contain as Much as a Spoon’s Worth of Microplastics, New Research Suggests

The amount of microplastics in the human brain appears to be increasing over time: Concentrations rose by roughly 50 percent between 2016 and 2024, according to a new study
