A team of neuroscientists at The Azrieli National Institute for Human Brain Imaging and Research, in Israel, has found that people who have lost the ability to smell have slightly different breathing patterns than those with ...

Speaking, singing, coughing, laughing, yelling, yawning, chewing—we use our jaws for many purposes. Each action requires a complex coordination of muscles whose activity is managed by neurons in the brain. But it turns ...

A team of Lawrence Livermore National Laboratory (LLNL) researchers has discovered a promising new treatment to counteract the effects of fentanyl and related opioids. The new treatment could, over time, be a boon to doctors ...

Using stem cells generated from patients with a rare and severe form of autism spectrum disorder and intellectual disability, Scripps Research scientists have grown personalized "mini-brains" (or organoids) to study the disorder ...

Using a gene signature technique to tailor chemotherapy for patients with early triple negative breast cancer shows promise as a way to improve disease-free survival, finds a clinical trial published by The BMJ today.

Suicide risk is highest on Mondays and increased on New Year's Day, whereas suicide risk on weekends and Christmas varies by country and region, finds an analysis of data from 26 countries published by The BMJ today.

When a gene produces too much protein, it can have devastating consequences on brain development and function. Patients with an overproduction of protein from the chromodomain helicase DNA binding (CHD2) gene can develop ...

A new model for mechanical stress describes how growing organisms on a stiffer substrate can paradoxically worsen certain health outcomes while increasing lifespan, according to a USC Leonard Davis study. The study "Growth ...

If you cut your arm or undergo surgery, scarring can be a good thing; the scar tissue produced by cells called fibroblasts helps you heal. In most organs of the body, however, the accumulation of scarring (called fibrosis) ...

Within the human brain, movement is coordinated by a brain region called the striatum, which sends instructions to motor neurons in the brain. Those instructions are conveyed by two pathways, one that initiates movement ("go") ...

Scientists have created a 3D-printed model to mimic the specific conditions that spur the spread of cancer cells. The model, published in the journal Life Science Alliance, allows researchers to study a process previously ...

A series of three papers from neuroscientist David J. Anderson's laboratory, two in the journal Nature and one in the journal Cell, reveal new insights into the neural signals underlying internal emotional states, including ...
