Early findings about the emerging pandemic of a new strain of influenza A (H1N1) in Mexico are published today in Science.

Researchers from the MRC Centre for Outbreak Analysis and Modelling at Imperial College London, working in collaboration with the World Health Organisation and public health agencies in Mexico, have assessed the epidemic using data to the end of April. Their key findings are as follows:

CORVALLIS, Ore. – Two Oregon State University researchers have uncovered a pattern of distrust – and sometimes outright antagonism – among physicians at hospitals and midwives who are transporting their home-birth clients to the hospital because of complications.

Oregon State University assistant professor Melissa Cheyney and doctoral student Courtney Everson said their work revealed an ongoing conflict between physicians and midwives that is reflective of discord across the country.

High-quality videoconferencing can increase patient access to stroke specialists, especially in rural or other underserved areas; and a transient ischemic attack (TIA), once known as a "mini" or "warning" stroke, should be treated with the same urgency as a full-blown stroke, according to two separate scientific statements and a policy statement published today in Stroke: Journal of the American Heart Association.

Telemedicine Statement Highlights:

CAMBRIDGE, Mass.--MIT engineers and colleagues have built a new tissue scaffold that can stimulate bone and cartilage growth when transplanted into the knees and other joints.

The scaffold could offer a potential new treatment for sports injuries and other cartilage damage, such as arthritis, says Lorna Gibson, the Matoula S. Salapatas Professor of Materials Science and Engineering and co-leader of the research team with Professor William Bonfield of Cambridge University.

INDIANAPOLIS – While child booster car seat use has increased across the United States, many seats are improperly installed, leading to increase risk of serious injury for their little passengers.

Researchers from the Automotive Safety Program at Riley Hospital for Children and Indiana University School of Medicine have found that an alarming two-thirds of the booster seats observed in a study conducted throughout Indiana were not being used appropriately.

PITTSBURGH—With the U.S. Congress beginning to consider regulations on greenhouse gases, a troubling hypothesis about how the sun may impact global warming is finally laid to rest.

Carnegie Mellon University's Peter Adams along with Jeff Pierce from Dalhousie University in Halifax, Canada, have developed a model to test a controversial hypothesis that says changes in the sun are causing global warming.

MADISON, WI, May 4, 2009--Contrary to the prevailing view, cereal crops derive the majority of their nitrogen from the soil, not fertilizer. Soils differ considerably in microbial activities that determine nitrogen-supplying power, and these differences must be taken into account if nitrogen fertilizers are to be used efficiently. The Illinois Soil Nitrogen Test (ISNT) was developed for this purpose, and involves estimation of gaseous ammonia liberated by heating the soil with strong alkali in a Mason jar.

Now, new Danish research may have come up with an explanation as to where and how North Sea oil clings to underground rocks. This explanation could turn out to be the first step on the way to developing improved oil production techniques with the intent of increasing oil production from Danish oil fields.

A hydrogen-rich compound discovered by Stanford researchers is packed with promise of helping overcome one of the biggest hurdles to using hydrogen for fuel--namely, how do you stuff enough hydrogen into a volume that is small enough to be portable and practical for powering a car?

Here's some sweet news for honey lovers: Researchers in France are reporting development of a simple test for distinguishing 100 percent natural honeys from adulterated or impure versions that they say are increasingly being foisted off on consumers. Their study appears in ACS' Journal of Agricultural and Food Chemistry.
