A massive genome-wide association study (GWAS) of genetic and health records of 1.2 million people from four separate data banks has identified 178 gene variants linked to major depression, a disorder that will affect as many as one in every five people...
The psychedelic drug psilocybin, a naturally occurring compound found in some mushrooms, has been studied as a potential treatment for depression for years. But exactly how it works in the brain and how long beneficial results might last is still unclear...
Exposure to the rhinovirus, the most frequent cause of the common cold, can protect against infection by the virus which causes COVID-19, Yale researchers have found.
In a new study, the researchers found that the common respiratory virus jump-starts the...
The COVID-19 pandemic increased our feelings of paranoia, particularly in states where wearing masks was mandated, a new Yale study has shown. That heightened paranoia was particularly acute in states where adherence to mask mandates was low, the...
In recent years, scientists have discovered that non-immune system cells are surprisingly well armed to combat infection. Yale researchers have found a particularly powerful weapon in these cells’ arsenal — a protein that acts like a detergent to wipe out...
Yale researchers have discovered the underlying genetic cause of a rare childhood disorder that mimics inflammatory bowel disease, a finding that may help researchers uncover the roots of a host of other inflammatory and autoimmune disorders.
For the...
As a newborn mammal opens its eyes for the first time, it can already make visual sense of the world around it. But how does this happen before they have experienced sight?
A new Yale study suggests that, in a sense, mammals dream about the world they are...
The diagnosis of mental illnesses such as major depression, schizophrenia, or anxiety disorder is typically based on coarse groupings of symptoms. These symptoms, however, vary widely among individuals as do the brain circuits that cause them. This...
Video images capture for the first time in live animals the inexorable spread of the COVID-19 virus, tracking the infection as it moved from the noses of mice to the lungs and other organs over the course of six days, in a new study led by researchers at...
As opioid overdose deaths rose during the COVID-19 pandemic, people seeking treatment for opioid addiction had to wait nearly twice as long to begin methadone treatment in the United States than in Canada, a new Yale study has shown.
In both countries...
