In cystic fibrosis, lungs feed deadly bacteria

In cystic fibrosis, Pseudomonas aeruginosa is a much-feared pathogen. The bacterium easily colonizes the lungs of people with cystic fibrosis, leading to chronic infections that are almost impossible to eradicate and are ...

Scientists discover why brown fat is good for people's health

Rutgers and other scientists have discovered how brown fat, also known as brown adipose tissue, may help protect against obesity and diabetes. Their study in the journal Nature adds to our knowledge about the role of brown ...

Neuroscience

Researchers repair faulty brain circuits using nanotechnology

Working with mouse and human tissue, Johns Hopkins Medicine researchers report new evidence that a protein pumped out of some—but not all—populations of "helper" cells in the brain, called astrocytes, plays a specific ...

A new way to stop cancer cells from killing their healthy neighbors

One of the reasons cancer cells are so robust against the body's natural defenses is that they are in fact human cells, and as such they have the innate machinery not only to trick the body's defense and maintenance systems, ...

Too many antioxidants may cause lung cancer spread

A new study explains why lung cancer spreads faster in patients with certain genetic changes, and suggests that taking vitamin E, long thought of as preventive, may cause the same spread.

Gene networks reveal transition from healthy to failing heart

Scientists investigating heart failure have been limited to studying diseased heart tissue in the lab—understandably, as people don't tend to pluck out a healthy heart for the sake of research. But now, scientists with ...

How common gut bacteria trigger a lethal autoimmune disease

What causes the immune system, designed to protect us, to turn on the body and attack healthy cells? Common bacteria that reside in the human gut may be partly to blame, say Yale researchers, who studied the origins of a ...

Researchers spot mutations that crop up in normal cells as we age

Cell division is not perfect. As we get older, mutations often appear in genes in normal cells. Most of these mutated cells and their progeny—called "somatic clones"—have no effect on our health, but a tiny fraction can ...
