Growth factor protects key brain cells in Alzheimer's models
Memory loss, cognitive impairment, brain cell degeneration and cell death were prevented or reversed in several animal models after treatment with a naturally occurring protein called brain-derived neurotrophic factor.

Trailblazing rural community shows green heating oil a viable option
An historic British town has placed itself at the cutting edge of green technology by hosting the world's first trial of a renewable heating oil that can be used in existing boilers.

Scripps scientists create first crystal structure of an intermediate particle in virus assembly
A research team at the Scripps Research Institute has been able to produce the first crystal structure of a virus particle caught in the midst of assembling its impenetrable outer protein coat.

A Zen discovery: Unrusted iron in ocean
Iron dust, the gold of the oceans and rarest nutrient for most marine life, can be washed down by rivers or blown out to sea or -- a surprising new study finds -- float up uncorroded from the sea floor.

Scientists discover key factor in controlling the breakdown of bone
A new study demonstrates that a chemical mediator in the blood that influences immune cell migration also plays a key role in maintaining the balance between the build-up and breakdown of bones in the body.

Biotech scientists team with curators to stem decay of world's art, cultural heritage
Many of the world's cultural treasures are creations made of organic materials such as paper, canvas, wood and leather which, in prolonged warmth and dampness, attract mold, micro-organisms and insects, causing decay and disintegration.

Revolutionary microchip uses 30 times less power
In the first real-world test of a revolutionary type of computing that thrives on random errors, scientists have created a microchip that uses 30 times less electricity while running seven times faster than today's best technology.

Mama whales teach babies where to eat
University of Utah biologists discovered that young right whales learn from their mothers where to eat, raising concern about their ability to find new places to feed if Earth's changing climate disrupts their traditional dining areas.

That gut feeling may actually reflect a reliable memory
You know the feeling. You make a decision you're certain is merely a

While focusing on heart disease, researchers discover new tactic against fatal muscular dystrophy
Based on a striking similarity between heart disease and Duchenne muscular dystrophy, researchers at Columbia University Medical Center have discovered that a new class of experimental drugs for heart failure may also help treat the fatal muscular disorder.

International study identifies gene variants associated with early heart attack
The largest study ever completed of genetic factors associated with heart attacks has identified nine genetic regions -- three not previously described -- that appear to increase the risk for early-onset myocardial infarction.

U of Minnesota-led study reveals mysteries of deep-sea nutrients
Iron dust, the rare but necessary nutrient for most life, can not only be washed into the ocean from rivers or blown out to sea, but it can bubble up from the depths of the ocean floor, a new study led by a University of Minnesota scientist shows.

Scientists deconstruct cell division
The last step of the cell cycle is the spectacularly dynamic and complicated mitosis phase, which leads to the duplication of one mother cell into two daughter cells.
