New technique shows how cells interpret genetic information
A surprising amount of the DNA sequence in the genes of humans and other higher organisms ends up on the cutting-room floor, so to speak, spliced out by the cellular machinery that turns genetic code into functional proteins.

Muddy Mayan mystery made clearer by researchers working in the bajos
University of Cincinnati professors Nicholas and Vernon Scarborough found evidence of a major environmental transformation that helps to explain a long-standing archaeological puzzle: Why would the Maya live in an area where the primary water source is little more than mud half of the year?

Research shows climate change could push bats northward
Research published in the most recent edition of Nature, shows that climate change will cause the northern limit of the winter range of the North American little brown bat (Myotis lucifugus) to extend northward by approximately 5 km per year over the next century.

New NW research institute will turn ag wastes into energy and useful products
Four Northwest research organizations are bringing together industry, processors, growers, universities and federal laboratories to develop new methods for converting agricultural and food processing residue and wastes into commercially valuable

Sprawl may threaten wildlife in reserves
Rural sprawl may be driving species toward local extinction. New research suggests that ranchettes in the Yellowstone area could degrade the best habitat for birds and so cut their population growth below sustainable levels.

More fallout from plaque ruptures in store for heart attack survivors
The blood clot that causes a heart attack may not act alone.

Faulty gene may explain why some fall ill at high altitudes
Two slight variations in a gene that helps maintain lung function increase the risk of high altitude sickness, a rare but potentially deadly breathing disorder, according to a report in today's rapid access issue of Circulation: Journal of the American Heart Association.

Ghostly asteroids clue to missing matter
Astronomers have lost thousands of comets. An Australian physicist thinks they may still be there, just invisible and some of them potentially on a collision course with Earth.

Researchers shed light on early brain growth and autism
Children with autism exhibit abnormal brain development during the very early years of life, according to two separate studies published in the current issue of Neurology, the scientific journal of the American Academy of Neurology.

New horizons of nerve repair
It's sticky, it's a gel, it comes in a tube, but this is no greasy kids' stuff.

ESA benefits grizzly bears
The debate over the Endangered Species Act ranges all the way from making it weaker to making it stronger, but there has been little good evidence for either side.

Brain reserve capacity and its role in preventing clinical signs of Alzheimer's disease studied
Identifying factors that increase the reserve capacity of the brain and enable people to tolerate the pathological changes that occur in the brains of people with Alzheimer's disease offers a new and potentially powerful approach to delaying the clinical signs of the Alzheimer's and other neurodegenerative diseases.

Dust in 'Earth's attic' could hold evidence of planet's earliest life
The dust has been piling up in Earth's attic -- the moon -- for billions of years.
