What your genes can, and cannot, tell us about your personality

A meta-analysis of 46 cohorts involving 611,037 to 1.14 million participants identified 1,260 lead genetic variants associated with the Big Five personality traits, including 824 in previously unlinked genomic regions. The associations were broadly consistent across cohorts and measurement contexts, while polygenic analyses linked personality-related genetics to health, behavior, psychopathology, and life outcomes, although effects were modest and could not predict individual behavior.

New tool amplifies and visualizes tiny protein changes

Imagine a brain teaser where the challenge is to spot the difference between two nearly identical sandcastles.

Salk researchers isolate specific neurons controlling complex social behaviors

Our brains constantly integrate information about both our internal state and our surroundings to determine how we behave.

Researchers maintain brain organoids for longer than ever before

An international team of researchers has maintained brain organoids, three-dimensional models of human brain tissue, for longer than ever before.

UVA researchers find how postoperative delirium may set the stage for dementia

UVA Health researchers have discovered how a form of delirium that often strikes older patients after surgery may set the stage for dementia – and identified a drug that could reverse the underlying brain changes.

Targeting single gene reverses developmental deficits in adult mice

Some of the symptoms of neurodevelopmental disorders (NDDs) such as autism spectrum disorder and epilepsy may result from dysfunction of certain neurons in the brain and their ability to change their properties in response to experiences-a process called experience-dependent plasticity.

Study reveals a previously unknown ability of the brain to repair itself

The brain evidently can regenerate itself better than previously assumed after injuries or certain autoimmune diseases.

New 3D brain tissue model accelerates Alzheimer's drug development

How can Alzheimer's research be made faster, better, and more effective? After decades of intensive research worldwide and despite recent therapeutic advances, scientists have not managed to fully arrest the progress of the disease.

Cell village approach reveals genetic differences in cell fitness

How readily a cell divides and how well it survives is fundamental to life, shaping everything from organ size to the body's ability to withstand disease.

Study reveals how DNA misfolding causes congenital heart disease

Congenital heart disease is the most common birth defect, affecting approximately 1 in 100 babies born each year. One of the many causes for this disorder is having only one functional copy of the gene TBX5, instead of two healthy copies, inherited from parents.

Study reveals dynamic remodeling of genome architecture during brain aging

Researchers have discovered that the human brain undergoes widespread age-related changes in genome regulation beginning in midlife that may help explain why aging is the greatest risk factor for neurodegenerative diseases such as Alzheimer's.

Short-term immunosuppressive therapy briefly restores autism-like brain changes in adult mice

A new mouse study led by UCLA Health suggests that inflammation during pregnancy can trigger autism-like changes in offspring, but also that those brain and behavior effects may be rapidly but temporarily reversible in adulthood with a short-term dose of the immunosuppressive drug rapamycin.

Sleeping longer may signal early Alzheimer's-related brain changes

Regularly sleeping long hours each night is associated with higher levels of an Alzheimer's-related protein in the blood, even accounting for other health factors, suggests a new study from UT Health San Antonio, the academic health center of The University of Texas at San Antonio.

New review highlights astrocytes' role in chronic traumatic encephalopathy

Researchers from Kansas City University School of Medicine have published a scoping review examining the role of astrocytes in chronic traumatic encephalopathy (CTE).

Study uncovers genetic clues behind sex differences in Parkinson's disease

New research presented today (Wednesday) at the Federation of European Neuroscience Societies (FENS) Forum 2026 has discovered some of the genetic changes in brain cells that may help to explain why more men than women develop Parkinson's disease.

Single cocaine exposure causes lasting brain cell changes in mice

Researchers studying the impact of cocaine in mice have found that just one exposure to the drug can create changes in brain cells that persist for at least two weeks.

New viral model triggers Parkinson's symptoms without using toxins

Scientists usually use animal models when studying Parkinson's disease because these models mimic the disease well.

Iron overload gradually increases neurons' vulnerability to neurodegeneration

Neurodegenerative diseases affect tens of millions of people worldwide. Among these, Alzheimer's and Parkinson's diseases are the most common; in the United States alone, the Alzheimer's Disease Association and Parkinson's Foundation report roughly 7 million people with Alzheimer's and another million with Parkinson's.

A night without sleep alters neural connections in human brains

A night without sleep produced increased markers of connections between brain cells, showing that sleep in humans may be important for restoring cellular balance in the brain, according to a study published June 23rd in the open access journal PLOS Biology by David Elmenhorst from the Forschungszentrum Jülich Institute of Neuroscience and Medicine in North Rhine-Westphalia, Germany, and colleagues.

Fish oil supplements show little benefit for Alzheimer's prevention

Americans spend more than $1 billion annually on fish oil supplements, in part due to purported cognitive benefits from the omega-3 fatty acids they contain, essential nutrients that help form brain cell connections needed for cognition.
