Can lie detectors be trusted?

Lie detectors have never been so widely used. Claim on your insurance or apply for housing benefit, and you could find yourself having to satisfy a piece of machinery as well as a human inquisitor. But can the results be trusted? Patrick Barkham reports.

Scientists study Fla. coral reef changes (AP)

AP - A nine-day mission that began Monday in the world's only permanent working undersea laboratory is like living in a fishbowl in more ways than one: Anyone with an Internet connection can watch the researchers work and hang out 60 feet below the...

Mercury concentrations in fish respond quickly to increased deposition

A joint Canadian-American research team have, for the first time, demonstrated that mercury concentrations in fish respond directly to changes in atmospheric deposition of the chemical. The international team`s research began in 2001 at the Experimental Lakes in Northern Ontario and is featured in this week`s Proceedings of the National Academy of Sciences.

Scientists unlock secrets of protein folding

A team led by biophysicist Jeremy Smith of the University of Tennessee and Oak Ridge National Laboratory has taken a significant step toward unraveling the mystery of how proteins fold into unique, three-dimensional shapes.

Researchers shed new light on hybrid animals

What began more than 50 years ago as a way to improve fishing bait in California has led a University of Tennessee researcher to a significant finding about how animal species interact and that raises important questions about conservation.

Scientists identify fundamental brain defect, probable drug target in fragile X syndrome

Scientists have discovered how the gene mutation responsible for fragile X syndrome--the most common inherited form of mental retardation--alters the way brain cells communicate. In neurons cultured from laboratory rats, the scientists also were able to reverse the effects of the mutation using a drug targeted to the specific site in an upstream pathway of the defect. The finding could lead to...

Mars orbiter in safe mode after glitch (AP)

AP - The Mars Odyssey orbiter was in safe mode Monday after a computer glitch prevented the 6-year-old spacecraft from relaying data from the twin rovers rolling across the Martian surface.

Allergy-related Asthma More Common In Children Living In Affluent Countries

Children with allergic sensitizations in economically developed countries are much more likely to develop asthma than similarly sensitized children in poorer countries, according to a new article. Researchers tested allergic sensitization as well as asthma in 8-12 year old children. Altogether, children living in affluent countries with allergic sensitizations were 4 times as likely to have asthma...

Cholesterol Tests At 15 Months Of Age Proposed

Children could have their cholesterol levels tested at about 15 months of age to prevent heart disease later in life, according to doctors. High cholesterol which runs in families is known as familial hypercholesterolaemia. It affects about two in every 1000 people and causes very high levels of low density lipoprotein or "bad cholesterol" in the blood. It carries a high risk of death from...

Galaxy hunting made easy

Astronomers using the European Southern Observatory's Very Large Telescope have captured nearly a dozen galaxies, marking a major development in exploring the universe.

Adobe's 3Q Profit Beats Predictions

(AP) -- Adobe Systems Inc. reported Monday that its third-quarter profit more than doubled from last year, setting a revenue record and easily exceeding Wall Street's expectations as the software company comes off its biggest-ever product launch.

Prep schools revive agriculture programs (AP)

AP - At St. Andrew's School, where chestnut trees tower over the Tudor-style buildings and crisply manicured grounds filmed for "Dead Poets Society," it's a safe bet few of the future Ivy Leaguers plan to become farmers. Yet on the edge of exclusive boarding school's campus, just beyond the tennis courts and soccer fields, sprout rows of green peas, sunflowers, zucchini and squash in a 2-acre...

Glass Of Wine Can Help Find New Mineral Deposits

The key to finding new mineral deposits could be to start looking with a glass of wine or a soft drink. In a surprising piece of spare-time research, scientists has found that chemical ingredients in these drinks have the ability to dissolve weakly-bound metals into solution.
