Science Debate 2008 is a nonpartisan effort to promote a public discussion of science and technology policy in the coming U.S. Presidential election.
Supported by numerous university presidents, Nobel Laureates, and other scientific leaders, the effort appears to have reached viability with the announcement of its co-chairs, two congressmen from different political parties.

A type of beetle that lives its entire life burrowing through stored grain has been found to lack full colour vision, and what’s more the vision it does have breaks the rules. Most other insects have trichromatic vision – they are sensitive to ultraviolet, blue and long wavelength light. In a report published in the online open access journal Frontiers in Zoology, scientists reveal that this beetle has lost photoreceptors that are sensitive to blue wavelengths.

Scientists have for the first time identified brain sites that fire up more when people make impulsive decisions. In a study comparing brain activity of sober alcoholics and non-addicted people making financial decisions, the group of sober alcoholics showed significantly more “impulsive” neural activity.

Up to 20 meters long and weighing as much as 20 tons, its enormous size gives the whale shark (Rhincodon typus) its name. Known as the ‘gentle giant’ for its non-predatory behavior, this fish, with its broad, flattened head and minute teeth, eats tiny zooplankton, sieving them through a fine mesh of gill-rakers. Listed as a rare species, relatively little is known about whale sharks, which live in tropical and warm seas, including the western Atlantic and southern Pacific. However, a new study combines computer-assisted photographic identification with ecotourism to study the rare species and suggests whale shark populations in Ningaloo, Western Australia are healthy. The study appears in the Ecological Society of America’s January issue of Ecological Applications.

Archaeological evidence shows that bone skates (skates made of animal bones) are the oldest human powered means of transport, dating back to 3000 BC. Why people started skating on ice and where is not as clear, since ancient remains were found in several locations spread across Central and North Europe.

It’s good news that we are living longer, but bad news that the longer we live, the better our odds of developing late-onset Alzheimer’s disease. Many Alzheimer’s researchers have long touted fish oil, by pill or diet, as an accessible and inexpensive “weapon” that may delay or prevent this debilitating disease. Now, UCLA scientists have confirmed that fish oil is indeed a deterrent against Alzheimer’s, and they have identified the reasons why.

A new study of combat-exposed Vietnam War veterans shows that those with injuries to certain parts of the brain were less likely to develop post-traumatic stress disorder (PTSD). The findings, from the National Institutes of Health (NIH) and the National Naval Medical Center, suggest that drugs or pacemaker-like devices aimed at dampening activity in these brain regions might be effective treatments for PTSD.

A chair that undulates, a mouse that vibrates, a monitor suspended over a desk on a movable arm. These are some of the kinds of newfangled ergonomic products that Alan Hedge, international authority on office ergonomics, studies to see if they can prevent repetitive motion injuries among the estimated 100 million people who now use computers in the United States.

Inch by power-conserving inch, drivers on Earth have moved the Mars rover Spirit to a spot where it has its best chance at surviving a third Martian winter — and where it will celebrate its fourth anniversary (in Earth years) since bouncing down on Mars for a projected 90-day mission in January 2004.

Reading is an important skill, so it’s not surprising it gets a lot of attention from researchers. Reading is an ancient skill — at least in some parts of the world — but not so old that we don’t know when it was invented (as opposed to, for instance, basic arithmetic). And, unlike language, it appeared recently enough in most of the world that it’s unlikely that evolution has had time to select for reading skill…which would explain the high prevalence of dyslexia.
