Scientists have joined forces in a groundbreaking assessment on the status of marine fisheries and ecosystems.
The two-year study, led by Boris Worm of Dalhousie University and Ray Hilborn of the University of Washington and including an international team of 19 co-authors, shows that steps taken to curb overfishing are beginning to succeed in five of the 10 large marine ecosystems that the
KIGALI, Rwanda (July 27, 2009) -- Government health officials from 13 African countries today launched the first-ever push for accreditation of the continent's medical laboratories, starting a process that the World Health Organization (WHO) and the U.S. Government believe will be an historic step to strengthen health systems and lead to better care for patients.
Researchers at the Johns Hopkins Malaria Research Institute have for the first time produced a malarial protein (Pfs48/45) in the proper conformation and quantity to generate a significant immune response in mice and non-human primates for use in a potential transmission-blocking vaccine.
London, 2 July 2009 -- The partners of Research4Life announced today at the World Conference of Science Journalists 2009 that a new research impact analysis has demonstrated a dramatic rise in research output by scientists in the developing world since 2002.
Banning or restricting the use of certain types of fishing gear could help the world’s coral reefs and their fish populations survive the onslaughts of climate change according to a study by the ARC Centre of Excellence for Coral Reef Studies at James Cook University, the Wildlife Conservation Society, and other groups.
The international team of scientists has proposed that bans on fishing gear
Baboons whose mothers have strong relationships with other females are much more likely to survive to adulthood than baboons reared by less social mothers, according to a new study by researchers at UCLA, the University of Pennsylvania and other institutions.
Los Angeles, London, New Delhi, Singapore and Washington DC (May 29, 2009) ? Those in the United States living with HIV/AIDS are more likely to use marijuana than those in Kenya, South Africa or Puerto Rica to alleviate their symptoms, according to a new study published in Clinical Nursing Research, published by SAGE.
A recently completed international multi-center clinical trial has found that acyclovir, a drug widely used as a safe and effective treatment to suppress herpes simplex virus-2 (HSV-2), which is the most common cause of genital herpes, does not reduce the risk of HIV transmission when taken by people infected with both HIV and HSV-2.
LINTHICUM, MD, April 26, 2009-Two studies presented at the 104th Annual Scientific Meeting of the American Urological Association (AUA) show that adult circumcision reduces the risk of contracting the human immunodeficiency virus (HIV) and the risk of coital injury!!--without reducing pleasure or causing sexual dysfunction.
Scientists have long debated the evolution of language. Did it emerge along with the appearance of modern homo sapiens, 130,000-200,000 years ago? Or did it happen as late as 50,000 years ago, explaining the cultural ferment at that time?
The first study to examine the probability of HIV infection per act of heterosexual sex among a population with multiple sexual partners has found that uncircumcised men have more than twice the risk of acquiring HIV than do circumcised men. In the study, published in the Feb. 15 issue of The Journal of Infectious Diseases, now available online, Jared Baeten and colleagues from the United States and Kenya collected detailed sexual data from a group of male Kenyan truckers and, using statistical models, developed infectivity measures that estimate the per-sexual-act probability of HIV transmission. The study is the first to calculate the probability of infection for men who have multiple, concurrent heterosexual partners, which was found to be significantly higher than infectivity rates calculated in the past from studies of monogamous couples. Their results may help explain the rapid spread of HIV in settings where circumcision is not common and multiple sexual partnerships are.
In a finding that surprised researchers, a recent three-year study of five baboon groups at the foot of Mount Kilimanjaro in Kenya reveals that baboon fathers overwhelming side with their offspring when intervening in disputes. The study, which appears in the Sept. 11 issue of the journal Nature, was funded by the National Science Foundation, the Chicago Zoological Society, the L.S.B. Leakey Foundation and the National Geographic Society. Not that baboons have a bad-dad reputation, but their links to females and immature baboons is rather loose by primate standards. For example, females and males have multiple mating partners, and they do not form permanent bonds with each other.
An international team of scientists has discovered a novel genetic trait that protects its carriers against the deadliest forms of malaria, while people without the trait are more likely to succumb to its fatal consequences. This trait -- a mutation or "polymorphism" in the NOS2 gene -- controls the production of nitric oxide, a small chemical that can kill parasites and prevent malaria disease.
