Black girls who use marijuana are more likely to engage in risky sexual acts and contract a sexually transmitted disease, a new study finds.
The study, by Emory University public health researchers, is being presented at the International AIDS Conference in Mexico City. It analyzed the marijuana use and self-reported sexual behavior of 439 sexually active black females between the ages of 15 and 21.
The world's population of critically endangered western lowland gorillas received a huge boost today when the Wildlife Conservation Society released a census showing massive numbers of these secretive great apes alive and well in the Republic of Congo.
A new study in SCI's Journal of the Science of Food and Agriculture shows that konjac gum and sesame seed extract may offer protection against different strains of E. coli and Salmonella bacteria.
The study by Dr Petra Becker et al from Wageningen University and Research Centre, the Netherlands, shows that these foodstuffs act as binders for E. coli and Salmonella bacteria. The bacteria attach themselves to the fibrous foods instead of the gut cells of the host.
DURHAM, N.C. -- Tiny fossilized teeth excavated from an Indian open-pit coal mine could be the oldest Asian remains ever found of anthropoids, the primate lineage of today's monkeys, apes and humans, say researchers from Duke University and the Indian Institute of Technology.
COLUMBUS, Ohio -- A new study suggests that it may be easier for people living in small metropolitan areas to get out of poverty than it is for those living in large metro areas.
The study by researchers at Ohio State University and Oklahoma State University found that despite an increase in the number of jobs created during the 1990s, many people living in large metro areas across the United States failed to find jobs.
Using sophisticated computer modelling techniques they have also calculated that the bite force of the great white's extinct relative, the gigantic fossil species Carcharodon megalodon (also known as Big Tooth) is the highest of all time, making it arguably the most formidable carnivore ever to have existed.
Contrary to the belief that HIV-infected injection drug users (IDUs) receive less benefit from highly active antiretroviral therapy (HAART), new research finds little difference in the survival rate between IDUs and non-IDUs after 4-5 years of receiving HAART, according to a study in the August 6 issue of JAMA, a theme issue on HIV/AIDS.
BOSTON — Homeowners in disadvantaged neighborhoods are more likely to vote than renters and those who own homes in more privileged communities, according to research to be presented at the annual meeting of the American Sociological Association (ASA).
A University of North Carolina-Chapel Hill research team led by sociologist Kimberly Manturuk investigated the relationship between homeownership and political participation and found that as neighborhood disadvantage increases, homeowners become more likely to vote while renters are less likely to do so.
Criminals who use firearms may find it much harder to evade justice in future, thanks to an ingenious new bullet tagging technology developed in the UK.
The tiny tags – just 30 microns* in diameter and invisible to the naked eye – are designed to be coated onto gun cartridges. They then attach themselves to the hands or gloves of anyone handling the cartridge and are very difficult to wash off completely.
DAVIS, CALIF. — Those who know someone who died in the Iraq War or 9/11 terrorist attacks are less likely to approve of President Bush's performance in office than people who have no such connections, according to new research from the University of California, Davis. The pattern holds true for Republicans as well as Democrats, conservatives as well as liberals, and across all races, ages, education levels and incomes.
The research appears in the August issue of the American Sociological Review, the flagship journal of the American Sociological Association.
Tour operators and airlines are wasting an ideal opportunity to warn travellers about the risk of contracting malaria in specific countries, say infectious disease experts on BMJ.com today.
The authors reviewed 27 travel brochures from British tour companies and found that only 12 contained any information about malaria, yet they all featured holidays to African countries where the disease is endemic.
When academic articles are "open access" or free online, they get read more often, but they don't -- going against conventional wisdom -- get cited more often in academic literature, finds a new Cornell study.
The reason, suggest Cornell graduate student Philip Davis and colleagues, including three Cornell professors, is that most researchers probably already have all the access they need to relevant articles.
ROCHESTER, Minn. - The world-record pace for the marathon continues to improve for both men and women. For men, the record pace for the marathon is now about as fast as the record pace for the 10,000-meter run just after World War II. Today, champion athletes are running more than four times farther at speeds of well under five minutes per mile.
How can this be? Are humans simply built better or is there something else behind the mind-blowing speeds on the racetrack?
WASHINGTON, DC – The U.S. Climate Change Science Program (CCSP) today announced the release of the report "Climate Models: An Assessment of Strengths and Limitations," the 10th in a series of 21 Synthesis and Assessment Products (SAPs) managed by U.S. federal agencies. Developed under the leadership of the U.S. Department of Energy (DOE), this report, SAP 3.1, describes computer models of the Earth's climate and their ability to simulate current climate change.
Geoscientists have long presumed that, like today, the tropics remained warm throughout Earth's last major glaciation 300 million years ago.
New evidence, however, indicates that cold temperatures in fact episodically gripped these equatorial latitudes at that time.
