Your mother was right; broccoli is good for you. Long associated with decreased risk of cancer, broccoli and other cruciferous vegetables — the family of plants that also includes cauliflower, cabbage, collard greens, Brussels sprouts and kale — contain a molecule that inactivates a gene known to play a role in a variety of common

In a series of recently published studies using animals and people, Johns Hopkins Medicine researchers say they have further characterized a set of chemical imbalances in the brains of people with schizophrenia related to the chemical glutamate. And they figured out how to tweak the level using a compound derived from broccoli sprouts. They say

Viruses are masterful invaders. They cannibalize host cells by injecting their genetic material, often making thousands of copies of themselves in a single cell to ensure their replication and survival. Some RNA viruses insert their genetic material as a single piece, while others chop it up into pieces. The latter are aptly named segmented viruses.

Yale researchers have pinpointed a key reason why people are more likely to get sick and even die from flu during winter months: low humidity. While experts know that cold temperatures and low humidity promote transmission of the flu virus, less is understood about the effect of decreased humidity on the immune system’s defenses against

Repetition can be useful if you’re trying to memorize a poem, master a guitar riff, or just cultivate good habits. When this kind of behavior becomes compulsive, however, it can get in the way of normal life — an impediment sometimes observed in psychiatric illnesses like Tourette’s syndrome and autism spectrum disorders. Now, Rockefeller scientists

Bioengineers have cleared a major hurdle on the path to 3D printing replacement organs with a breakthrough technique for bioprinting tissues. The new innovation allows scientists to create exquisitely entangled vascular networks that mimic the body’s natural passageways for blood, air, lymph and other vital fluids. The research is featured on the cover of this

Researchers at the Hebrew University of Jerusalem (HU) have found a way to transform skin cells into the three major stem cell types that comprise early-stage embryos. The work (in mouse cells) has significant implications for modelling embryonic disease and placental dysfunctions, as well as paving the way to create whole embryos from skin cells.

A state-of-the-art brain-machine interface created by UC San Francisco neuroscientists can generate natural-sounding synthetic speech by using brain activity to control a virtual vocal tract — an anatomically detailed computer simulation including the lips, jaw, tongue, and larynx. The study was conducted in research participants with intact speech, but the technology could one day restore

A small clinical trial has shown that gene therapy can safely correct the immune systems of infants newly diagnosed with a rare, life-threatening inherited disorder in which infection-fighting immune cells do not develop or function normally. Eight infants with the disorder, called X-linked severe combined immunodeficiency (X-SCID), received an experimental gene therapy co-developed by National

People in almost every region of the world could benefit from rebalancing their diets to eat optimal amounts of various foods and nutrients, according to the Global Burden of Disease study tracking trends in consumption of 15 dietary factors from 1990 to 2017 in 195 countries, published in The Lancet. The study estimates that one in
