Howard Hughes Medical Institute (HHMI) scientists have developed a strategy for finding disease-causing mutations that lurk in only a small fraction of the body's cells. Such mutations can cause significant problems, but cannot be detected with traditional methods of genetic testing, as well as newer, more costly genome sequencing technologies.

 

Algae might seem easy to ignore, but they are the ultimate source of all organic matter that marine animals depend upon. Humans are increasingly dependent on algae, too, to suck up climate-warming carbon dioxide from the atmosphere and sink it to the bottom of the ocean. Now, by using a combination of satellite imagery and laboratory experiments, researchers have evidence showing that viruses infecting those algae are driving the life-...

A new search for dark matter will soon be underway after a second generation experiment was selected by US funding agencies. Most physicists believe that dark matter particles make up most of the mass of the universe, but these particles have never been observed directly since they neither emit nor absorb light at any wavelength.

Study demonstrates that the immune system can produce cells with stem cell properties that can create different types of cells such as neurons in the adult animal. Researchers have strived for years to determine how neurons are produced and integrated into the brain throughout adult life. In an intriguing twist, scientists reporting in the August 11 issue of the Cell Press journal Developmental Cell provide evidence that adult-born...

While diabetes rates are on the rise and are having serious effects on millions of people’s health, researchers studying grizzly bears have now discovered a natural state of diabetes that serves a real biological purpose and is also reversible. The research reveals how natural biology, through evolutionary experimentation, can teach us new things about how animals naturally cope with conditions that would cause disease in humans....
