MIT scientists have discovered a new class of compact DNA modifying systems called OMEGAs that naturally shuffle DNA in bacteria and can be engineered to work in human cells.

Anxiety, addiction, and other psychiatric disorders are often characterized by intense states of what scientists call arousal: The heart races, blood...

Study provides new insight on how experiences shape our current mood New insight on how our experiences during a task or interaction shape our current mood has been published today in the open-access eLife journal. The study suggests that early experiences may have a larger effect on our mood than more recent events. These findings hold implications for the timing of events in experimental or clinical settings, and suggest new directions for mood interventions tailored to individual patients. ...

Findings further support paramagnetic rim lesions as MS biomarker Paramagnetic rim lesions (PRL), a manifestation of chronic white matter inflammation seen on MRI, were associated with elevated levels of serum neurofilament light chain (NfL), a marker of axonal damage, in people with multiple sclerosis (MS), a cross-sectional study found. MS patients with two or more

In aging humans, aerobic exercise training increases gray and white matter volume, enhances blood flow, and improves memory function. ...

In a study of healthy volunteers, National Institutes of Health researchers have mapped out the brain activity that flows when we learn a new skill, such

Mechanisms of many human chronic diseases involve abnormal action of the immune system and/or altered metabolism. The microbiome, an important regulator of metabolic and immune-related phenotypes, has been shown to be associated with or participate in the development of a variety of chronic diseases. Viruses of bacteria (i.e., “phages”) are ubiquitous and mysterious, and several studies have shown that phages exert great control over the behavior—and misbehavior—of their host bacteria. T...

Image credit: Kampmann Lab When a single gene in a cell is turned on or off, its resulting presence or absence can affect the function and survival of the cell. In a new study appearing May 24 in Nature Neuroscience, UCSF researchers have successfully catalogued this effect in the human neuron by separately toggling each of the 20,000 genes in the human genome. In doing so, they’ve created a technique that can be employed for many different cell types, as well as a database where other resea...
