A Cornell University experiment on a fly-sized treadmill shows that tiny fly with super-acute hearing can not only match the species thought to have the best directional hearing -- Homo sapiens -- but it does so with a fraction of the head space.

UCSD researchers discover protein essential for formation of skin's outer layer
Using test-tube analysis and studies in mice, researchers identified a protein called a keratinocyte differentiation- inducing factor, or kDIF, which is required for the production of the thin layer of fibrous (keratinzed) epidermal cells on the skin's surface.

'Heart block' with pacemaker is safe treatment for atrial fibrillation
For patients who have not responded to medications, treating atrial fibrillation by permanently blocking a key portion of the heart's electrical system and replacing it with a pacemaker leads to survival rates that are as good as those for patients receiving conventional drug therapy, according to a Mayo Clinic study published in this week's New England Journal of Medicine.

Scientists find just how discriminating a worm can be: Unique system of overlapping odor sensors discovered
With only 32 of its 302 nerves dedicated to detecting the odors that drift through its world, the lowly roundworm seems hard pressed to smell food, let alone discriminate friend from foe.

Educator: Proposed federal trust fund would help make knowledge produced by universities available to all
A proposed $18 billion federal trust fund to underwrite a digital revolution in America's public and nonprofit institutions would help create an unparalleled opportunity to make knowledge produced by the nation's research universities available to everyone, an academic leader says.

Researchers discover an easier way to make a complex but useful molecule
The architecture of star-shaped molecules gives them valuable properties. Now Virginia Tech chemists have discovered a way to make these complex molecules more easily and efficiently.

Measurements of an exposed earthquake fault helps scientists understand subsurface faults' behavior, improve hazard forecasts
Geological scientists know something of the causes of earthquakes, and they know where many faults are located.

Amphibian mortality linked to climate change
Toad embryos in the Cascade Range of Oregon appear to be dying due to a chain of events that's ultimately linked to climate change, demonstrating both the importance of large scale global trends and the complexity of their impact on individual species.

Tobacco taxes put money where the mouth is, says Canadian Dental Association
New tobacco control initiatives announced today were music to the ears of Canadian dentists.

Officials design Web-based software for managing hazardous chemicals
Stanford officials have designed a commercially available software system to manage chemical inventories at major research institutions and large-scale industries.

Novel antibiotic provides rapid relief from symptoms of tonsillitis/pharyngitis, study shows
Study on a new investigational antibiotic KETEKĀ® (telithromycin) presented ECCMID, Istanbul today: NOVEL ANTIBIOTIC PROVIDES RAPID RELIEF FROM SYMPTOMS OF TONSILLITIS/PHARYNGITIS Five day treatment with KETEKĀ® (telithromycin) provides more rapid symptomatic and bacterial relief than a ten day course of treatment with penicillin V for patients with GABHS tonsillitis/pharyngitis.

Oral therapy for leukemia can treat an otherwise incurable form of abdominal cancer, study finds
A drug that made national headlines for its success against chronic myelogenous leukemia (CML) has shrunk and even eliminated some tumors in a patient with a rare and otherwise incurable form of gastrointestinal cancer, scientists at Dana-Farber Cancer Institute and collaborators in Finland and at Oregon Health Sciences University (OHSU) report in the April 5 issue of the New England Journal of Medicine.

'Good' cholesterol reduces stroke risk

Warming tropical oceans changing northern climate
A progressive warming of tropical oceans, likely due to the buildup of greenhouse gases in the atmosphere, is driving major climate changes observed in the Northern Hemisphere since 1950, according to a new study by NCAR's James Hurrell and NOAA's Martin Hoerling, published in the April 6 issue of Science.

Charged molecules may improve processing of polymers
Virginia Tech researchers have determined that adding ionic compounds to polyesters, such as are commonly used in soft drink bottles (PET), makes it easier to process the material.

Tree biomass is the same in tropic or temperate climes
Conventional wisdom that tropical regions have more tree biomass than temperate zones seems to be wrong.
