Possible Hepatitis C Vaccine

Hepatitis C virus infects up to 500,000 people in the UK alone, many of the infections going undiagnosed. It is the single biggest cause of people requiring a liver transplant in Britain. Now scientists have found monoclonal antibodies which may make a successful vaccine a reality.

Protecting Beaches From Agricultural Pollution

Bathing beaches and lakes in Europe could fail the new cleanliness standards set by the 2006 Bathing Waters Directive, but a new risk assessment tool developed by rural studies and water management experts may help reduce the transfer of disease causing bacteria from the farmed environment, according to scientists.

Psychiatrists Are The Least Religious Of All Physicians

A survey of the religious beliefs and practices of American physicians has found that the least religious of all medical specialties is psychiatry. Among psychiatrists who have a religion, more than twice as many are Jewish and far fewer are Protestant or Catholic. The study also found that religious physicians, especially Protestants, are less likely to refer patients to psychiatrists, and more...

Rare Breeds Of Farm Animals Face Extinction

With the world's first global inventory of farm animals showing many breeds of African, Asian, and Latin American livestock at risk of extinction, scientists have called for the rapid establishment of genebanks to conserve the sperm and ovaries of key animals critical for the global population's future survival.

School-based Overweight Prevention Program May Cut Risk Of Eating Disorders Among Girls

Researchers set out to determine if an obesity prevention program called 5-2-1-Go! could reduce the risk of eating disorder symptoms and harmful weight-control behaviors in adolescents. The study showed that almost 4 percent of middle-school girls receiving only their regular health education began vomiting or abusing laxatives or diet pills, but just 1 percent of the girls in the 5-2-1-Go!...

Smokers Are More Likely To Develop Dementia

People who smoke are more likely to develop Alzheimer's disease or dementia than nonsmokers or those who smoked in the past, according to a new study. The study followed nearly 7,000 people age 55 and older for an average of seven years. Over that time, 706 of the participants developed dementia. People who were current smokers at the time of the study were 50 percent more likely to develop...

The Bonobo Handshake

What's it like to work with relatives who think sex is like a handshake, who organize orgies with the neighbors, and firmly believe females should be in charge of everything? On September 11, a group of young researchers will head to the Congo to study our mysterious cousin, the bonobo.

Tiny Carbon Nanotubes Show Big Germ-fighting Potential

In nanoscience's version of a David-and-Goliath story, scientists are reporting the first direct evidence that carbon nanotubes have powerful antimicrobial activity, a discovery that could help fight the growing problem of antibiotic resistant infections. Their research is in the area of single-walled carbon nanotubes.

What Men And Women Really Want In a Mate

While humans may pride themselves on being highly evolved, most still behave like the stereotypical Neanderthals when it comes to choosing a mate, according to new research. The researchers found that though individuals may claim otherwise, beauty is the key ingredient for men while women, the much choosier of the sexes, leverage their looks for security and commitment.


Aluminum In Breast Tissue: A Possible Factor In The Cause Of Breast Cancer

A new study has identified a regionally-specific distribution of aluminum in breast tissue which may have implications for the cause of breast cancer. Scientists have found that the aluminum content of breast tissue and breast tissue fat was significantly higher in the outer regions of the breast, in close proximity to the area where there would be the highest density of antiperspirant.

Baby's Conception And Birth Can Influence Dream Content In New Moms

The conception and birth of a child are emotional events that influence the dreams of most new mothers. In a surprisingly high number of cases, this influence reflects negative aspects of maternal responsibility, depicting the new infant in dreamed situations of danger and provoking anxiety in the mother that often spills over into wakefulness. These kinds of dreams are also accompanied by complex...

Faster Climate Change Means Bigger Problems

The debate about what constitutes "dangerous anthropogenic interference with the climate" has almost exclusively focused on how much the temperature can be allowed to increase. But we have perhaps just as much reason to be concerned about how quickly these changes take place. The UN Framework Convention on Climate Change (UNFCCC) aims to avoid what is called "dangerous anthropogenic interference...

Rosetta's Target Comet: Lumpy, Bumpy, Fluffy And Layered

Observational and theoretical studies of Comet 67P/Churyumov-Gerasimenko, the target of ESA's Rosetta mission, are building a detailed portrait of the comet's nucleus as it travels around the Sun. Surprisingly, although the comet was not active, they found that a faint dust trail is visible in the images of the comet, extending more than 500 000 km along the comet's orbital path.

Up, Up And Away -- To Venus

Scientists hope to learn more about climate changes here on Earth by studying Venus. A prototype balloon could eventually study the planet's surface and examine its atmosphere and the bizarre winds and chemistry within it. A team of JPL, ILC Dover and NASA Wallops Flight Facility engineers designed, fabricated and tested the balloon.

Biosensors To Probe The Metals Menace

New technology can warn people if their local water or air is contaminated with dangerous levels of toxic heavy metals and metal-like substances. They are studying the changes that take place in a unique water microbe when it is exposed to arsenic, cadmium and lead -- industrial and natural contaminants around the world.

Humpback Whales Recorded Clicking And Buzzing While Feeding For First Time

For the first time, researchers have recorded "megapclicks" -- a series of clicks and buzzes from humpback whales apparently associated with nighttime feeding behaviors -- in and around NOAA's Stellwagen Bank National Marine Sanctuary. This acoustically active species has been known to produce complex "songs" on their breeding grounds, but knowledge of sound production on northern feeding grounds...

Mice Used In Research Helpful In Multiple Research Areas

Mice that are part of the Collaborative Cross project at Oak Ridge National Laboratory are helping scientists around the world learn more about possible causes of drug abuse, diabetes, sleep disorders, stress and pain, kidney disease and a number of other conditions that affect millions of people.

Passive Smoking Could Cause 1.9 Million Excess Deaths From COPD In China

Exposure to passive smoking is linked to increased prevalence of chronic obstructive pulmonary disease (COPD). This association could cause 1.9 million excess deaths* among never smokers in China. The scientists found that people exposed to high levels of passive smoking (equivalent to 40 hours a week for more than five years) were on average 48% more likely to develop COPD.

Social, Church Activities May Protect Against Adolescent Smoking

Preventing youth smoking could take a village or a neighborhood. Church and school activities may help reduce smoking among youth in disadvantaged areas, according to a new survey. African-American youths reported less cigarette use overall than white youths. Across racial lines however, young people involved in extracurricular school activities or programs at church were less likely to smoke even...

Warning Signs Of Pregnancy Danger

Warnings signs such as increased stress could indicate that pregnancy-induced hypertension is reaching life-threatening levels. The condition is variable and can change quickly. A higher number of symptoms, such as headaches and dizziness, could also mean the condition is getting worse. Also known as preeclampsia and gestational hypertension, pregnancy-induced hypertension occurs at about 20 weeks...

Drug-sensitive 'Traffic Cop' Tells Potassium Channels To Get Lost

Our brains are buzzing with electrical activity created by sodium and potassium ions moving in and out of neurons through specialized pores. To prevent the constant chatter from descending into chaos the activity of these ion channels has to be tightly regulated. One possibility is to issue the channels a ticket straight to the cellular dumpster, discovered researchers.
