While high school graduates in Oslo, Norway, partied hard for two weeks last spring during the so-called Russ graduation festivities, levels of the drug ecstasy spiked about 10-fold in the city’s sewer system, according to new research. In the past few years, water quality specialists have monitored such illicit drug use through sewage sampling there and in other cities, including London and San Diego, to observe the effects of drug control policies.
However, current analytical methods require expensive equipment to collect water samples and don’t allow for continuous sampling of wastewater. Now researchers demonstrate that so-called passive filters provide an efficient and inexpensive means to measure drug use over weeks in municipal wastewater. With the samplers, they studied the ebbs and flows of 11 drugs in Oslo’s sewers for a year, including during the Russ celebrations (Environ. Sci. Technol., DOI: 10.1021/es201124j).

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.
