60 SECONDS

Reptile peril SNAKE oil, tortoise blood and caiman fat are lubricating a slippery slope towards extinction for many reptiles. At least 165 reptile species are used in concoctions prepared by folk healers around the world, and 88 are already on endangered species lists, according to a report

“While some reptile products are clinically proven, the efficacy of most is unknown” in Biodiversity and Conservation (DOI: 10.1007/s10531-007-93050). “East Asian freshwater turtles are under critical threat largely because of over-collection by the traditional medicine and food industries,” says lead author Rômulo Alves of the State University of Paraíba in Campina Grande, Brazil. While some reptile products are clinically proven, the efficacy of most of remains unknown. At worst, poor product hygiene can lead to dangerous illnesses such as salmonella infections, which have repeatedly occurred when people take rattlesnake pills. Alves has previously found that folk cures made from animal products fly off the shelves even in cities with good access to modern medicines, leaving him with scant hope of a fall in demand. “Conservation strategies will need to address the cultural aspects of folk medicine,” he says.

Australia’s federal court ruled on Tuesday that whaling by Japan in Australian waters is illegal. The conservation group Humane Society International estimates that more than 1300 whales were killed in Australian Antarctic waters between 2000 and 2006 by Kyodo Senpaku Kaisha, which has a permit to kill 985 whales this season. The government must now enforce the ruling.

Dying denied trial drugs

Gender bias IF YOU thought the glass ceiling for female scientists had been shattered, think again. Women are more likely to have their research published if the referees who peer review their work are unaware of their gender, a new study suggests. It has long been suspected that “single-blind” peer review – in which reviewers know a researcher’s identity but not vice versa – can lead to bias. Gender, nationality and nepotism have

“Double-blind peer review, in which no identities are revealed, would be fairer”

also been identified as biasing factors in the application process for research fellowships. Some suggest that double-blind peer review, in which neither side knows the other’s identity, would be a fairer system. To find out if this is true, Amber Budden at the University of Toronto in Canada and her colleagues looked at the gender of the authors of papers accepted by Behavioural Ecology before and after it switched to double-blind peer review in 2001. In the four years following the switch, 8 per cent more female authors had papers published compared to the previous four years (Trends in Ecology and –In need of protection– Evolution, DOI: 10.1016/
