New Study from Affymetrix Laboratories Points to Changing View of How Genome Works

Scientists at Affymetrix, Inc. (Nasdaq: AFFX) reported today in Science magazine online that they have completed a high-resolution scan of structure and function for nearly 30 percent of the human genome sequence. In collaboration with the National Cancer Institute, the research team used high-density GeneChip(R) microarrays to study every fifth base, on average, of 10 human chromosomes; they fou...

Changing ecosystems throw scientists mega-challenges

Accelerating environmental changes have presented humanity with some significant scientific and engineering challenges, according to the new National Science Foundation (NSF) report, Pathways to the Future: Complex Environmental Systems: Synthesis for Earth, Life and Society in the 21st Century. Among the changes the report cites are rapid shifts in climate and ecosystems, the degradation...

Scientists must offer solutions for conserving tropical forests in a rapidly changing world

As the future of the tropics unfolds, scientists must explain the dimensions and mechanisms of forest responses to rapid human-population increase and environmental changesAs human populations and their impacts on the world increase, tropical forests are changing in many different ways. Forests are being cleared, burned, logged, fragmented, and overhunted and an unprecedented pace, and they are...

Drug-resistant bacteria patterns in intensive care units changing nationally

A dangerous drug-resistant bacterium is becoming more prevalent in many intensive care units, according to an article in the Feb. 1 issue of Clinical Infectious Diseases, now available online. Methicillin-resistant Staphylococcus aureus (MRSA) is responsible for a variety of infections that patients often acquire in the hospital. Skin infections are the most common, but MRSA can also infec...

Beekeepers work hard for the honey, despite changing tupelo forest

Van Morrison sang about it, Peter Fonda starred in a movie about it, and people from all over the world will pay top dollar just to get some of it. Florida State University geography Professor J. Anthony Stallin...

Tastes great! Study shows brain's response to pleasing -- and changing -- tastes

We all have tastes we love, and tastes we hate. And yet, our "taste" for certain flavors and foods can change over time, as we get older or we get tired of eating the same old thing. And although the study...

Changing length of days reverses how estrogen affects aggressiveness in mice

New research shows how simply varying the length of daylight to which mice are exposed to can change how aggressively they react to other mice. However, in the long days of s...

Paramecia adapt their swimming to changing gravitational force

For many single-celled organisms living in water, the force is always against them. The classic example is the slipper-shaped paramecium, which consistently swims harder going up than going down, just to keep from sinking. Now physicists Karine Guevorkian and James Valles of Brown University have worked out a way to turn gravity on its head and see how the creatures respond. The researcher...

Computer with brain connections changing quality of life of paralyzed

Fundamental theories regarding consciousness, emotion and quality of life in sufferers of paralysis from Amyotrophic Lateral Sclerosis (ALS, also known as 'Lou Gerhig's disease') are being challenged based on new research on brain-computer interaction. ALS is a progressive disease that destroys neurons affecting movement. The study appears in the latest issue of Psychophysiology. The article revi...
