More than a watchdog
A study in mice shows the nervous system not only detects the presence of Salmonella in the gut but actively stops the organism from infecting the body by shutting the cellular gates that allow bacteria to invade the intestine and spread beyond it.

CAGEs lock up fats to treat obesity
Harvard researchers have found an orally administered liquid salt — choline and geranate — that can reduce the absorption of fats from food with no discernable side effects in rats, lowering total body weight by about 12 percent.

Learning not to fear
A study using mindfulness meditation showed changes over time in neural responses to pain and fear. The researchers found that changes in the hippocampus after mindfulness training were associated with enhanced ability to recall a safety memory, and thus respond in a more adaptive way.

A reliable clock for your microbiome
The microbiome is a treasure trove of information about human health and disease, but getting it to reveal its secrets is challenging, especially when attempting to study it in living subjects. A new genetic “repressilator” lets scientists noninvasively study its dynamics, acting like a clock that tracks how bacterial growth changes over time with single-cell…

William G. Kaelin Jr., the Sidney Farber Professor of Medicine at Harvard Medical School and the Dana-Farber Cancer Institute, is one of three winners of the 2019 Nobel Prize in physiology or medicine for discovering how cells sense and adapt to changes in oxygen availability, a process critical for survival.

Playing our song
Samuel Mehr has long been interested in questions of what music is, how music works, and why music exists. To help find the answers, he’s created the Music Lab, an online, citizen-science project aimed at understanding not just how the human mind interprets music, but why music is a virtually ubiquitous feature of human societies.

Exposing how pancreatic cancer does its dirty work
New research has found that pancreatic cancer actively destroys nearby blood vessels and replaces them with cancerous cells, blocking chemotherapy from reaching tumors. This insight could lead to new treatments that act by preventing cancer’s colonization of blood vessels.

How a zebrafish model may hold a key to biology
Martin Haesemeyer set out to build an artificial neural network that worked differently than fish’s brains, but what he got was a system that almost perfectly mimicked the zebrafish — and that could be a powerful tool for understanding biology.
