WUSTL researchers have shed light on one of the most important events in earth history, the conquest of land by plants. No would-be colonizer could have survived without the ability to deal with dehydration, a major threat for organisms accustomed to soaking in water. Clues to how the first land plants managed to avoid drying out are provided by the drought-tolerant moss Physcomitrella patens.

The Eiffel Tower and other world-class icons viewable online via webcams are getting a new three-dimensional look thanks to an innovative, browser-based application recently unveiled by Austin Abrams, a Ph.D. candidate at Washington University in St. Louis.

Washington University School of Medicine in St. Louis has received a five-year, $13 million grant from the Bill & Melinda Gates Foundation to improve efforts to eliminate two parasitic diseases, elephantiasis and river blindness. The award is believed to be the largest global health grant so far to the University.

Younan Xia, Ph.D., the James M. McKelvey Professor of Biomedical Engineering, has been ranked as one of the top 10 chemists in the world by The Times Higher Education, a magazine based in London. 

Four WUSTL faculty have been named fellows of the American Association for the Advancement of Science (AAAS), the world’s largest general scientific society. The highest honor awarded by AAAS, the rank of fellow is bestowed upon members by their peers in recognition of scientifically or socially distinguished efforts to advance science or its applications.

The Alvin J. Siteman Cancer Center and Washington University have received from Alvin J. Siteman a commitment for an endowment that will provide at least $1 million annually to advance pioneering investigations into cancer prevention, diagnosis and treatment. The new endowment establishes the Alvin J. Siteman Cancer Research Fund, which will provide support for transformational scientific contributions that address the challenges associated with overcoming cancer. 

WUSTL geoarcheologist Jennifer Smith, Ph.D., is featured a History channel documentary that solves a series of geological mysteries about the Sahara’s past. The show, part of the “How the Earth Was Made” series, explains why there are marine fossils embedded in the blocks of stone from which the pyramids are made and drawings of people swimming are scratched into the walls of desert caves.

Physics professor Stuart Solin, Ph.D., a “classic physics thinker” according to colleagues, lives by the scientific code of honesty and respect for evidence.

New calculations by an international group of theorists paint a better picture of the nature of quark stars and suggest a way for astronomers to find the quark stars among the neutron stars. But WUSTL physicist Mark Alford, commenting on the journal publication in a news article posted Jan. 15 at PhysicsWorld.com, suggests that the new work may not be the last word. Alford, who uses mathematical modeling to explore the properties of quark stars, contends that the mathematical theory it uses is only truly accurate when the quarks are millions of times denser than they are in real neutron stars.

An international team of researchers, including Erik Trinkaus, Ph.D. professor of anthropology in Arts & Sciences, has reanalyzed the complete immature dentition of a 30,000 year-old-child from the Abrigo do Lagar Velho, Portugal. The new analysis of the Lagar Velho child shows that these “early modern humans” were modern without being “fully modern.”
