In the scientists’ lounge aboard the BIO Hespérides one evening last March, Jordi Dachs points at the schedule for the next day’s oceanographic observations. The Spanish research vessel is chugging across the Indian Ocean at a speed of about ten knots. “The storm has put us seven hours behind,” warns Dachs, an environmental chemist at the Institute of Environmental Assessment and Water Research in Barcelona, Spain, whose responsibilities as chief scientist on the ship include planning researchers’ time and instrument use. About two dozen scientists brace themselves against the rhythmic pitching of the vessel. “We might not lower the sampling rosette all the way on some days,” says Dachs, “to save time.”
His suggestion fills the room with tension. Lowering and retrieving the rosette can take many hours, but the water samples it retrieves from the ocean’s depths — as much as 4 kilometres down — hold the biggest potential for new discoveries. Sampling excursions in the Indian Ocean’s deep waters are relatively rare, making the samples particularly valuable.
The quality of a wine is still in the palate of the beholder, but tasters agree that fruitiness is an important contributor. Spanish researchers now report that chemicals responsible for a wine’s foul, sweaty smells also produce its fruity flavor (J. Agric. Food Chem., DOI: 10.1021/jf1048657).

Monsanto acquired a stake in Sapphire Energy, a San Diego–based algae fuel company known for its prominent backers, including Bill Gates’s firm Cascade Investment, in Kirkland, Washington, and the Wellcome Trust, in London. Through the deal (figures were not disclosed), the St. Louis agriculture giant gains access to Sapphire’s expertise and technology for isolating algal traits that could be applied to agricultural genetic research.

Thirty years ago this month, scientists first reported the existence of AIDS, and in the intervening decades researchers have focused steady efforts on prevention, long-term treatments such as antiretroviral drugs, and patient care. What has fallen in and out of fashion during that time is seeking a ‘cure’ for HIV. That changed when scientists reported that they had cured one man of the virus through a bone marrow transplant (Blood117, 2791–2799, 2011). But the circumstances of that 2007 transplant were unique, and researchers say they are uncertain about how to fund additional cure-directed research without cannibalizing other components of the global HIV/AIDS research machine.
