​Overwhelmed by speculators trying to cash-in on a prized medicinal fungus known as Himalayan Viagra, two isolated Tibetan communities have managed to do at the local level what world leaders often fail to do on a global scale — implement a successful system for the sustainable harvest of a precious natural resource, suggests new research from Washington University in St. Louis.​

The Asian tiger mosquito (Aedes albopictus) was spotted in Houston in 1985 but can now be found in all of the southern states and as far north as Maine. To reconstruct its spread, scientists turned to the new discipline of landscape genetics. Correlating genetic patterns with landscape patterns, they concluded that the mosquito had hitched a ride along highways. One of only a handful of landscape genetics studies to track an invasive species, this is the first to detect hitchhiking.

The School of Engineering’s Yasutaka Furukawa, PhD, combines 3-D computer vision of indoor scenes with the capabilities of Google Maps and Google Earth to create a unique, high-resolution, photorealistic mapping experience of indoor spaces. Though he is starting with spaces like the New York museum The Frick Collection, he intends to bring his technology to St. Louis — specifically to Washington University’s Danforth Campus.

In the digital age in which we live, monitoring, security breaches and hacks of sensitive data are all too common. It has been argued that privacy has no place in this big data environment and anything we put online can and probably will be seen by prying eyes. In a new paper, noted Washington University in St. Louis privacy law expert Neil M. Richards, JD, makes the case that when properly understood, privacy rules will be an essential and valuable part of our digital future.

Climate change, water shortages and the loss of farmland to pollution and urban sprawl are making it increasingly difficult for farmers to feed the world’s growing population, agricultural scholars from four continents said this week at an international symposium held at Washington University in St. Louis.

The government of India’s Department of Biotechnology, Indian corporate leaders and Washington University in St. Louis have invested $2.5 million to launch the Indo-U.S. Advanced Bioenergy Consortium for Second Generation Biofuels (IUABC). The goal of the center is to increase biomass yield in plants and algae, enabling downstream commercial development for cost-effective, efficient and environmentally sustainable production of advanced biofuels.

The topic of the 2014 Robert M. Walker Distinguished Lecture the evening of Oct. 23 will be black holes. The speaker is Ramesh Narayan, a Harvard astrophysicist who has studied the event horizon and the spin of these celestial enigmas. The talk, which starts at 7 p. m. in Whitaker Hall on the Danforth Campus, is free and open to the public.

Scientists from the School of Engineering & Applied Science at Washington University in St. Louis have shown a new way to reverse or eliminate energy loss in optical systems such as lasers. They are doing so by, ironically, adding loss to a laser system to actually reap energy gains. In other words, they’ve invented a way to win by losing.​​​

Pharmaceutical companies have largely abandoned the business of discovering and developing antibiotics and our stock of these “miracle drugs” is beginning to shrink. Michael Kinch and his colleagues at Washington University in St. Louis are working to create new models for drug discovery that could replace the failed private enterprise model.

Washington University in St. Louis alumnus W. E. Moerner, PhD, has been awarded the Nobel Prize in chemistry. Moerner shares the award, announced Oct. 8 by the Royal Swedish Academy of Sciences, with Eric Betzig, PhD, of the Howard Hughes Medical Institute, and Stefan W. Hell, PhD, of the Max Planck Institute for Biophysical Chemistry, in Germany. The trio received the award for developing super-resolved fluorescence microscopy.​
