With a goal to reduce HIV risk behaviors, researchers investigated whether gay men and male sex workers in Mexico City would participate in a conditional cash transfer program that encourages HIV prevention education and regular testing. A new study in the European Journal of Health Economics reports the price that would get more than 75-percent participation: $288 a year.

PROVIDENCE, R.I. [Brown University] — Studies have found that conditional cash transfer programs, in which governments pay citizens if they consistently practice societally beneficial behaviors, have improved pediatric health care and education in Mexico, increased HIV testing in Malawi, and reduced sexually transmitted infections in Tanzania. Public health researchers therefore investigated whether the idea could be applied to HIV risk behaviors among gay men and male sex workers in Mexico City. A new study reports not only that some members of those populations would change behavior for conditional cash payments, but the exact prices they would accept. (more…)

Scientists Find Oldest Dinosaur – or Closest Relative Yet

Researchers have discovered what may be the earliest dinosaur, a creature the size of a Labrador retriever, but with a five foot-long tail, that walked the Earth about 10 million years before more familiar dinosaurs like the small, swift-footed Eoraptor and Herrerasaurus.

The findings mean that the dinosaur lineage appeared 10 million to 15 million years earlier than fossils previously showed, originating in the Middle Triassic rather than in the Late Triassic period. (more…)

New Global Subsidy that Provides Access to Most Effective Malaria Drugs Shows Promise

UCLA infectious diseases doctor played key role in finance strategy for therapy

A new international program, conceived in part by a UCLA physician, has rapidly transformed access to lifesaving anti-malarial drugs by providing cheap, subsidized artemisinin-based combination therapies in seven African countries that account for a quarter of the world’s malaria cases.

The first independent evaluation of the Affordable Medicines Facility–malaria (AMFm) program was recently published in the journal The Lancet. The program is based at the Global Fund in Geneva, an international financing institution dedicated to disbursing funds to prevent and treat infectious diseases. The evaluation shows that the program improved access to key artemisinin combination therapies, or ACTs, which offer broader protection and less antibiotic resistance than anti-malaria medications currently available in those African nations.

Hunter-Gatherers Expend Same Calories as Average Americans

Taking in too many calories far outweighs getting too little exercise as a cause of obesity, according to a study of a hunter-gatherer society co- authored by Yale anthropologist Brian Wood and recently published in the July issue of the journal PLoS One.

Using state-of-the-art technology to measure the daily energetic expenditure of the Hazda, a foraging people of Tanzania, Wood and co-authors Herman Pontzer (Hunter College) and David Raichlen (University of Arizona) discovered that even though these last remaining hunter-gatherers in Africa are quite physically active, they expend on average no more calories in a day than the adult population of the industrialized world. Given the total lack of obesity among the Hadza, whose average daily calorie consumption is far lower than that found in the developed world, the researchers concluded that increased caloric intake is the main source of rising obesity in Western populations.

Internet Use Promotes Democracy Best in Countries That Are Already Partially Free

COLUMBUS, Ohio — Although use of the internet has been credited with helping spur democratic revolutions in the Arab world and elsewhere, a new multinational study suggests the internet is most likely to play a role only in specific situations.

Researchers at Ohio State University found that the internet spurs pro-democratic attitudes most in countries that already have introduced some reforms in that direction. (more…)

*Some Dinosaurs Were as Warm as Most Modern Mammals*

PASADENA, Calif.—Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold or warm blooded. When dinosaurs were first discovered in the mid-19th century, paleontologists thought the y were plodding beasts that had to rely on their environments to keep warm, like modern-day reptiles. But research during the last few decades suggests that they were faster creatures, nimble like the velociraptors or T. rex depicted in the movie Jurassic Park, requiring warmer, regulated body temperatures like in mammals.

Now, a team of researchers led by the California Institute of Technology (Caltech) has developed a new approach to take body temperatures of dinosaurs for the first time, providing new insights into whether dinosaurs were cold or warm blooded. By analyzing isotopic concentrations in teeth of sauropods, the long-tailed, long-necked dinosaurs that were the biggest land animals to have ever lived—think Apatosaurus (also known as Brontosaurus)—the team found that the dinosaurs were about as warm as most modern mammals.

*An encounter with 35 young girls in Kenya prompted Margo Day to start a secondary school there. The school will also be a refuge for girls who fled their homes to avoid the traditional practice of female genital mutilation.*

REDMOND, Wash. — When Margo Day went on a safari last year in Africa, she more or less knew what to expect. She had traveled in Kenya and Tanzania 16 years earlier, where she had what she calls a life-changing experience watching lions, elephants and wildebeests roam the plains. She returned to Kenya last fall to share that experience with her 19-year-old niece, Gail.

What Day didn’t expect was meeting 35 young girls who would change her life. But Day, who serves as West regional vice president of U.S. Small and Midmarket Solutions and Partners at Microsoft, had also wanted to do some philanthropic work on her trip. So she and her niece spent the last four days of their tripin remote northern Kenya with a team from World Vision, an international nonprofit that helps children, families and communities overcome poverty and injustice. The day before Day and her niece flew back to the U.S., they visited a primary school that also housed a rescue center run by World Vision. (more…)
