Scientists have discovered a molecular pathway that works through the immune system to regenerate damaged kidney tissues and may lead to new therapies for repairing injury in other organs. The study may have significant medical ramifications as currently there are no effective treatments for acute kidney injury — a growing problem in hospitals and clinics.

An analysis of newly available climate data shows that summer fog along the California coast has declined significantly in the past century, though it is unclear whether this is a natural variation or a result of human activity. The new report links summer high pressure cells above the northwest California coast to frequent fog. When [...]

The great promise of induced pluripotent stem cells is that the all-purpose cells seem capable of performing all the same tricks as embryonic stem cells, but without the controversy.

Despite good intentions, the push to privatize government functions and insistence upon “free trade” that is too often unfair has caused declining food production, increased poverty and a hunger crisis for millions of people in many African nations, researchers conclude in a new study.

Scientists have successfully transplanted most of the “nose” of the mosquito that spreads malaria into frog eggs and fruit flies and are employing these surrogates to combat the spread of the deadly and debilitating disease that afflicts 500 million people.

Stem cells intentionally cut and then repair their own DNA as a mechanism of activating genes that promote the development of new tissues, according to new research. This is a new way of activating a gene, and it could change how researchers think about tissue development, stem cells and cancer.

Electrodes on the surface of the brain show that using imagined movements to control a computer cursor can generate larger-than-life brain signals after less than 10 minutes of training.

Researchers have identified a mechanism used by the tuberculosis bacterium to evade the body’s immune system and have identified a compound that blocks the bacterium’s ability to survive in the host, which could lead to new drugs to treat tuberculosis.
