Natural Sciences and Engineering Research Council grantee Peter Austin and three other researchers at the Institute for Clinical Evaluative Sciences in Toronto have just completed a survey of…

In his Jan. 23 State of the Union address, President George Bush outlined his plan to reduce the nation's dependency on foreign oil by requiring the production of 35 billion gallons a year of…

Modern human mothers are probably happy that they typically have one, maybe two babies at a time, but for early hominids, low birth numbers combined with competition often spelled extinction. "The…

A scientific panel revealed today that rising global demand for healthy seafood has exceeded wild capture fisheries' ability to provide all fish meals demanded by consumers. Aquaculture -- or the…

The notion that more information about the science of human-caused climate change will spur effective problem solving by American society is just flat wrong, according to a University of Colorado at…

  A University of Queensland microbiologist is part of an international team that has identified a bacterial gene that may affect climate and weather.   Dr Phil Bond, from UQ's Advanced…

An international team of researchers from 19 countries has identified one gene and a previously unidentified region of another chromosome as the location of another gene that may contribute to a…

Though the cell membrane is a protective barrier, it also plays a role in letting some foreign material in — via ion channels that dot the cell’s surface. Now new research from the Nobel Prize…

Liquid or gas flowed through cracks penetrating underground rock on ancient Mars, according to a report based on some of the first observations by NASA's Mars Reconnaissance Orbiter. These fluids…

“Regressive evolution,” or the reduction of traits over time, is the result of either natural selection or genetic drift, according to a study on cavefish by researchers at New York University’s…

A strong wind blows sand and dust across the Mediterranean Sea from the Libyan Desert, located in the northeast section of the Sahara Desert, to Sicily and the southern tip of the Italian Peninsula…

Imagine a cancer treatment tailored to the cells in a patient’s body, each person receiving a unique treatment program. This is what Natural Sciences and Engineering Research Council grantee Thomas…

Scientific studies of why foods such as Brussels sprouts and stout beer are horribly bitter-tasting to some people but palatable to others are shedding light on a number of questions, from the…

Industrial agriculture faces painful challenges: the end of cheap energy, depleted water resources, impaired ecosystem services, and unstable climates. Scientists searching for alternatives to the…

From roundworm to human, most cells in an animal’s body ultimately come from stem cells. When one of these versatile, unspecialized cells divides, the resulting “daughter” cell receives instructions…

Blurring boundaries High up on the bluffs overlooking the Pacific Ocean in southern California, strange animals scurry about in their cages. They eat, drink, copulate and occasionally try to run away…

There are always some kinds of records that you just can’t believe. These cases are outside the borders of rational thinking. The youngest mother was a 5 year old Peruvian girl. I thought that it’s…

Whether they're fighting postoperative soreness or relieving chronic discomfort from conditions such as cancer, morphine and other opioids are powerful weapons against pain. Now, in research…

Fundamental theories in evolutionary biology have long proposed that biological kinship is the foundation of the family unit. It not only creates the sense of altruism that exists among genetically…

Certain cancer risks can be passed down through families, the result of tiny changes in a family's genetic code. But not all genetic changes are deadly. To help medical counselors and physicians…
