Recurrent bouts of systemic lupus erythematosus, marked by the body’s immune system attack of its own tissues, closely tracked with measureable upticks in growth in the gut of a certain species of bacteria.

New research from NYU Grossman School of Medicine shows that bacterial blooms of the gut bacterium Ruminococcus blautia gnavus occurred at the same time as disease flare-ups in five of 16 women with lupus of diverse racial backgrounds studied over a four-year period. Systemic lupus erythematosus involves damaging inflammation, especially in the kidneys, but also in joints, skin, and blood vessels. Four of these study patients with R...

Benzodiazepine use and discontinuation is associated with nervous system injury and negative life effects that continue after discontinuation, according to a new study from researchers at the University of Colorado Anschutz Medical Campus.

The study was published today in the journal PLOS ONE.

“Despite the fact that benzodiazepines have been widely prescribed for decades, this survey presents significant new evidence that a subset of patients experience long-term neurological complications,” said Alexis Ritvo, M.D, M.P.H., an assistant professor in psychiatry at the University of Colorado School of Medicine and medical director of the nonprofit Alliance for Benzodiazepine Best Practices...

A team of researchers led by Feng Zhang at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT has uncovered the first programmable RNA-guided system in eukaryotes—organisms that include fungi, plants, and animals.

In a study published in Nature, the team describes how the system is based on a protein called Fanzor. They showed that Fanzor proteins use RNA as a guide to target DNA precisely, and that Fanzors can be reprogrammed to edit the genome of human cells...

Researchers at the Centre for Genomic Regulation (CRG) in Barcelona and the Max Delbrück Center for Molecular Medicine in the Helmholtz Association in Berlin have revealed how cells accelerate changes to their identity, a process known as cell fate conversion.

The study, published today in the journal eLife, has implications for cancer research as the disease often arises from errors in cell fate decisions. The study could eventually lead to new methods of accelerating or manipulating the molecular mechanisms involved in the formation of cancer.

Central to the study is C/EBPα...
