Investigators at Mass General Brigham have uncovered how resistance to chemotherapies may occur in some cancers. Researchers focused on a pathway that harnesses reactive oxygen species (ROS) to kill cancer cells. The study found that mutations to VPS35, a key player in this pathway, can prevent…

How a critical enzyme keeps potentially dangerous genes in check
You may have heard of the fantastic-sounding “dark side of the genome.” This poorly studied fraction of DNA, known as heterochromatin, makes up around half of your genetic material, and scientists are now starting to unravel its role in your cells.
For more than 50 years, scientists have puzzled…

Researchers develop new DNA test for personalized treatment of bacterial vaginosis
Roughly one out of three women ages 14-49 in the United States develop a vaginal bacterial imbalance known as bacterial vaginosis (BV) during their lifetime. BV is characterized by unpleasant odors, and potentially painful side effects, as well as the risk of associated health issues later in…

Brain channels ‘stopped in time’ reveal chemical flow that enables learning and thinking
In an effort to understand how brain cells exchange chemical messages, scientists say they have successfully used a highly specialized microscope to capture more precise details of how one of the most common signaling molecules, glutamate, opens a channel and allows a flood of charged particles…

New approach could treat anthrax beyond the ‘point of no return’
Anthrax, an infectious disease caused by the bacterium Bacillus anthracis, is often treatable in its early stages. But once the disease has progressed beyond the “point of no return” after just a few days, patients are almost certainly doomed.
In a new Nature Microbiologystudy, University of…

PET imaging confirms direct involvement of dopamine in cognitive flexibility
For the first time, scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility, according to new research published in the March issue of The Journal of Nuclear Medicine. PET imaging shows that the brain increases dopamine production when completing cognitively…
