Significant Gas Resource Discovered In Gulf Of Mexico

Posted: 01 Jun 2009 08:00 AM PDT

The Gulf of Mexico contains very thick and concentrated gas-hydrate-bearing reservoir rocks which have the potential to produce gas using current technology. Recent drilling by a government and industry consortium confirm that the Gulf of Mexico is the first offshore area in the United States with enough information to identify gas hydrate energy resource targets with potential for gas production.

Genetic Risk Factor For Testicular Cancer Discovered: Gene Is Associated With A Three-fold Increase In Risk

Posted: 01 Jun 2009 08:00 AM PDT

Researchers have uncovered variation around two genes that are associated with an increased risk of testicular cancer, which is the most common cancer among young men -- it now affects seven out of 100,000 white men in the United States each year. The discovery is the first step toward understanding which men are at high risk of disease.

Regular Light Bulbs Made Super-efficient With Ultra-fast Laser

Posted: 01 Jun 2009 08:00 AM PDT

An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can.

Obese Women Should Not Gain Weight During Pregnancy, Study Suggests

Posted: 01 Jun 2009 08:00 AM PDT

A new study challenges the prevailing wisdom that to improve pregnancy outcomes, all women, even those who are obese, should gain weight during pregnancy. The study, first of its kind, found that obese pregnant women who followed a well-balanced diet and gained little or no weight had maternal-fetal outcomes that were equal to or better than those who gained substantial weight.

Positive Feedback Hint Between Tropical Cyclones And Global Warming

Posted: 01 Jun 2009 08:00 AM PDT

Tropical cyclones could be a significant source of the deep convection that carries moist air upward to the stratosphere, where it can influence climate, according to new research.

Pressure To Look Attractive Linked To Fear Of Rejection In Men And Women

Posted: 01 Jun 2009 08:00 AM PDT

People who feel pressure to look attractive are more fearful of being rejected because of their appearance than are their peers, according to a new study.

Combined Stem Cell-Gene Therapy Approach Cures Human Genetic Disease In Vitro

Posted: 01 Jun 2009 05:00 AM PDT

Scientists have catapulted the field of regenerative medicine significantly forward, proving in principle that a human genetic disease can be cured using a combination of gene therapy and induced pluripotent stem cell technology. The study is a major milestone on the path from the laboratory to the clinic.

Caffeine Shown As Effective At Reducing Exercise-induced Asthma Symptoms As An Albuterol Inhaler

Posted: 01 Jun 2009 05:00 AM PDT

A study found that the ingestion of caffeine within an hour of exercise can reduce the symptoms of exercise induced asthma (EIA).

Triage Technology With A Star Trek Twist: Tricorder-like Device

Posted: 01 Jun 2009 05:00 AM PDT

Scientists at the U.S. Department of Homeland Security are developing the Standoff Patient Triage Tool, a device that classic Star Trek fans will recognize for its resemblance to the medical diagnostic tool known as the tricorder.

Anemia Associated With Greater Risk Of Death In Heart Disease Patients

Posted: 01 Jun 2009 05:00 AM PDT

A new study has found that the presence of anemia in patients with chronic heart failure is associated with a significantly increased risk of death. The findings also show that anemia is associated with a poorer degree of left ventricular function and a lower left ventricular ejection fraction, an objective measure of cardiac function.

Environmental Pollution Increases Risk Of Liver Disease, Study Finds

Posted: 01 Jun 2009 05:00 AM PDT

A new study is the first to show that there is a previously unrecognized role for environmental pollution in liver disease in the general US adult population. This work builds upon the groups' previous research demonstrating liver disease in highly-exposed chemical workers.

Realistic Picture Of Dementia: Video Can Help Patients Make End-of-life Decisions

Posted: 01 Jun 2009 05:00 AM PDT

Viewing a video showing a patient with advanced dementia may help elderly patients plan for end-of-life care, according to a new study. The investigators found that participants who watched such a video in addition to listening to a verbal description of the condition were more likely choose receiving comfort care if they developed advanced dementia and also felt the video was helpful to their decision-making process.

Quicker, Cheaper SARS Virus Detector -- One Easily Customizable For Other Targets

Posted: 01 Jun 2009 02:00 AM PDT

Researchers say they've made a big improvement in a new breed of electronic detectors for viruses and other biological materials -- one that may be a valuable addition to the battle against epidemics.

Chicken Meat: Organic Acids, Plant Extracts And Irradiation Combine To Beat The Bacteria

Posted: 01 Jun 2009 02:00 AM PDT

A mixture of some organic acids and some extracts from plants turns out to be enough to greatly reduce pathogenic bacteria on chicken breast meat. Add some irradiation to the mix and it makes a lethal combination against the bacteria.

New Treatment Option For Patients With Chronic Hepatitis C

Posted: 01 Jun 2009 02:00 AM PDT

A new combination therapy of daily consensus interferon and ribavirin is effective for some people with chronic hepatitis C who do not respond to standard therapy.

Antibiotic-resistant Bacteria Found In Fertilizer, Finds Study Of Swedish Sewage Sludge

Posted: 01 Jun 2009 02:00 AM PDT

Vancomycin-resistant enterococci have been found in sewage sludge, a by-product of waste-water treatment frequently used as a fertilizer. Researchers point out the danger of antibiotic resistance genes passing into the human food chain.

Few Pharmacies Can Translate Prescription Labels Into Spanish

Posted: 01 Jun 2009 02:00 AM PDT

Surprisingly few pharmacies in the US are able to translate prescription medication instructions into Spanish, making it difficult for patients who speak only Spanish to understand how to take their medications properly, according to a new study. The first multi-state study investigating the ability of pharmacies to translate prescription labels found more than half of the pharmacies were unable to translate any labels or could do only a limited number of translations.

Satellite Detects Red Glow To Map Global Ocean Plant Health

Posted: 31 May 2009 11:00 PM PDT

Researchers have succeeded for the first time in measuring the physiology of marine phytoplankton through satellite measurements of its fluorescence -- an accomplishment that had been elusive for years. With this new tool, scientists will now be able to gain a reasonably accurate picture of the ocean's health and productivity about every week, all over the planet.

Protein 'Springs' Simplify Control Of Crustacean Limb Movements

Posted: 31 May 2009 11:00 PM PDT

Animals can simplify the brain control of their limb movements by moving a joint with just one muscle that operates against a spring made of the almost perfect elastic substance called resilin. This principle is analyzed and illustrated by striking photographs and high-speed video footage of the movements of the mouthparts of crabs and crayfish.

Study Expands Window For Effective Stroke Treatment

Posted: 31 May 2009 11:00 PM PDT

Once symptoms start, there's only a tiny window of time for stroke victims to get life-saving treatment. Now, research has cracked that window open a bit wider.
