Genetic information from an 800,000-year-old human fossil has been retrieved for the first time. The results shed light on one of the branching points in the human family tree, reaching much further back in time than previously possible.
As the coronavirus pandemic forces people to keep their distance, could this be robots‘ time to shine? A group of scientists think so, and they’re calling for robots to do the “dull, dirty, and dangerous jobs” of infectious disease management. Social distancing has emerged as one of the most effective strategies for slowing the spread […]
After months of deliberation, the Food and Drug Administration has asked all manufacturers of a particular heartburn medicine known as ranitidine, sold under several brands including Zantac, to withdraw their drugs because “unacceptable levels” of a possible carcinogen may develop in the pills over time. Specifically, the agency determined that levels of NDMA, an organic […]
The rich biodiversity of coral reefs even extends to microbial communities within fish, according to new research. The study reports that several important grazing fish on Caribbean coral reefs each harbor a distinct microbial community within their guts, revealing a new perspective on reef ecology.
WASHINGTON — A private equity-backed health care company is slashing its doctors’ benefits in response to the coronavirus pandemic, even as many of those same doctors work to treat patients infected with the virus.

Florida Gov. Ron DeSantis has refused to issue a statewide “stay-at-home” order to stem the spread of the novel coronavirus because the disease has not hit many areas of the state, he said.
In a new pre-clinical study published this week in the journal Leukemia, the research team of Children’s Hospital Los Angeles investigator Hisham Abdel-Azim, MD, MS, worked with colleagues to engineer T-cells to identify and target multiple sites on acute lymphoblastic leukemia cells instead of just one. The early collaboration points the way to future clinical […]
Researchers describe their discovery of a new mechanism that could contribute to the pathogenesis of inflammatory diseases. The scientists found that ZBP1, a protein best known for defending against incoming viruses, is activated by sensing an unusual form of cellular genetic material (Z-nucleic acids), leading to cell death and inflammation.
