Study reveals conflict between doctors, midwives over homebirth

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.

Videoconferencing can increase patient access to stroke specialists

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.

MIT: New tissue scaffold regrows cartilage and bone

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.

Riley Hospital-IU study finds booster car seats not being used appropriately

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.

Carnegie Mellon's Peter Adams finds no link

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.

Illinois Soil Nitrogen Test measures microbial nitrogen

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.

New Danish research shows how oil gets stuck underground

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.

High-pressure compound could be key to hydrogen-powered vehicles

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?

New test distinguishes impure honey from the real thing

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.

New nanocrystals show potential for cheap lasers, new lighting

For more than a decade, scientists have been frustrated in their attempts to create continuously emitting light sources from individual molecules because of an optical quirk called "blinking," but now scientists at the University of Rochester have uncovered the basic physics behind the phenomenon, and along with researchers at the Eastman Kodak Company, created a nanocrystal that constantly emits light.

First DNA Test Kit For H1N1 Influenza A (Swine Flu) Arrives One Week After Nancy Grace Has Moved On To New Hysteria

PrimerDesign Ltd, a UK firm founded by University of Southampton scientists, has won the race to produce the first DNA test kit for the Mexican swine flu.

The first shipment of rapid-results tests has been sent today directly to Mexico as well as many other territories to help authorities monitor the increasing number of suspected cases.

Project coordinator Dr Rob Powell said: "This past Sunday at midnight was a very special moment for us. We were able to show conclusively that the test works."

Nimbus rises in the world of cloud computing

Cloud computing is a hot topic in the technology world these days. Even if you're not a tech-phile, chances are if you've watched a lot of television or skimmed a business magazine, you've heard someone talking about cloud computing as the way of the future. While it's difficult to predict the future, a cloud computing infrastructure project developed at Argonne National Lab, called Nimbus, is demonstrating that cloud computing's potential is being realized now.

New nanotube coating enables novel laser power meter

The U.S. military can now calibrate high-power laser systems, such as those intended to defuse unexploded mines, more quickly and easily thanks to a novel nanotube-coated power measurement device developed at the National Institute of Standards and Technology (NIST).

Study examines novel patent foramen ovale closure system

LAS VEGAS, NV (May 8, 2009) — A new device designed to close a common heart defect known as a patent foramen ovale (PFO) is safe and effective at 90-days follow up, according to a new study released today at the Society for Cardiovascular Angiography and Interventions (SCAI) 32nd Annual Scientific Sessions in Las Vegas.

Vise squad: Putting the squeeze on a crystal leads to novel electronics

A clever materials science technique that uses a silicon crystal as a sort of nanoscale vise to squeeze another crystal into a more useful shape may launch a new class of electronic devices that remember their last state even after power is turned off. Computers that could switch on instantly without the time-consuming process of “booting” an operating system is just one of the possibilities, according to a new paper by a team of researchers spanning four universities, two federal laboratories and three corporate labs.*
