Crested Auklet Birds Rub Tick-repelling Perfume On Their Mates During Courtship:

Hitting it off with members of the opposite sex takes chemistry. University of Alaska Fairbanks researcher Hector Douglas has found that, for crested auklets, chemistry has both amorous and practical applications. The birds rub a citrus-like scent, secreted in wick-like feathers on their backs, on each other during courtship, a behavior called alloanointing. It is well known among some mammals, such as peccaries, but until now was not documented among birds. His research also indicates that the behavior could help protect the birds from parasites, such as ticks.

Natural Insecticide Re-created In The Lab:

Twenty-two years of dedicated research has finally resulted in success: In the journal Angewandte Chemie, a British team headed by Steven V. Ley at the University of Cambridge reports the first synthesis of azadirachtin, a natural compound that stops predatory insects from feeding.

Martian Life? Small Percentage Of Martian Soil Samples Could Have Biological Origin:

A new interpretation of data from NASA's Viking landers indicates that 0.1% of the Martian soil tested could have a biological origin.

Are Homosexual Civil Unions A 600-year-old Tradition?:

A compelling new study from the September issue of the Journal of Modern History reviews historical evidence, including documents and gravesites, suggesting that homosexual civil unions may have existed six centuries ago in France. The article is the latest from the ongoing "Contemporary Issues in Historical Perspective" series, which explores the intersection between historical knowledge and current affairs.

First Out-of-body Experience Induced In Laboratory Setting:

A neuroscientist working at UCL (University College London) has devised the first experimental method to induce an out-of-body experience in healthy participants. In a paper published in Science, Dr Henrik Ehrsson, UCL Institute of Neurology, outlines the unique method by which the illusion is created and the implications of its discovery.
