Malaria infects more than 300 million people every year, and more than a million die— 90% of them children under five, according to the World Health Organization. The disease is rampant in Africa, largely because of the parasite's growing resistance to drugs and the mosquito's to insecticides. puking of the science of malaria into the era ofgenomics and all of A plethora of papers accompathe attendant advantages," says nying the sequences shows that reAnthony S.

U.S. CHEMICAL R&D QUESTIONED Alleged work on nonlethal weapons raises treaty compliance issues

W

IN BRIEF: HONORED The National Academy of Engineering on Oct. 6 presented its 2002 Founders Award to University of Pennsylvania chemical and biochemical engineering emeritus professor Stuart W. Churchill. NAE cites Churchill's "outstanding" contributions in combustion, heat transfer, and fluid dynamics over a half century.

ITH ALL EYES FOCUSED ON

Iraq's chemical weapons these days, the possible involvement of the U.S. in chemical weapons development may also be an issue—although a very confusing one. The Sunshine Project, a small activist group, is in The Hague this week trying to tell delegates to the annual Conference of States Parties to the Chemical Weapons Convention (CWC) of its conviction that the U.S. is violating the convention with R&D into nonlethal chemical weapons. It would like the delegates to immediately request an inspection of the U.S. activity un-

der the treaty—something that is extremely unlikely A spokesman for the Defense Department's Joint Non-Lethal Weapons Directorate (fNLWD) tells C&EN that there is nothing to the charges and that the directorate is not involved in chemical weapons research. However, in a presentation last November to an academic research symposium on nonlethal technology, J N L W D identified calmatives (a military euphemism for mind-altering drugs) and malodorants as "new capabilities" under "chemical-based technologies." Under "challenges," the C W C was listed first. Under "an-

cillary technologies," J N L W D listed microencapsulation and long-range, precision delivery The Sunshine Project claims that government documents it has gathered and placed on its website (http://www.sunshineproject.org) "demonstrate beyond reasonable doubt that J N L W D is operating an illegal and classified chemical weapons program." J N L W D maintains that the erroneous charges are based on misinterpretation of the data. One example is J N L W D ' s work on developing a nonlethal round for the standard U.S. Army 81-mm mortar. This, combined with a request for methodologies to characterize the aerosols it produces and calculate ground-area coverage of gas clouds from air bursts at different altitudes, is a clear treaty violation, according to the Sunshine Project. However, according to J N L W D , the round is being developed as a nonchemical, nonlethal weapon, using such things as rubber bulletS.-MICHAELHEYLIN HTTP://PUBS.ACS.ORG/CEN
