Researchers at Columbia Engineering and Boston University have developed the first method to map evaporation globally using weather stations, which will help scientists evaluate water resource management, assess recent trends of evaporation throughout the globe, and validate surface hydrologic models in various conditions. The study was published in the April 1 online Early Edition of Proceedings of the National Academy of Sciences (PNAS).

Gases work with particles to promote cloud formation, study finds
Researchers at Columbia Engineering and Georgia Institute of Technology have published a study in the online Early Edition of Proceedings of the National Academy of Sciences (PNAS) showing—for the first time—that certain volatile organic gases can promote cloud formation in a way never considered before by atmospheric scientists. The study will be published the week of February 4, 2013.

Fast, low-cost device uses the cloud to speed up diagnostic testing for HIV, more
Samuel K. Sia, associate professor of biomedical engineering at Columbia Engineering, has taken his innovative lab-on-a-chip and developed a way to not only check a patient’s HIV status anywhere in the world with just a finger prick, but also synchronize the results automatically and instantaneously with central health-care records—10 times faster, the researchers say, than the benchtop ELISA, a broadly used diagnostic technique. The device was field-tested in Rwanda by a collaborative team from the Sia lab and ICAP at Columbia’s Mailman School of Public Health.
