5:55 PM | Berkeley Lab Builds ‘Artificial Forest’ to Harvest Solar Energy
Devices for artificial photosynthesis are often called “artificial leaves”. This leaves, however, are of no use unless you can create an “artificial forest” from them. Now, scientists with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory have reported the first fully integrated nanosystem for artificial photosynthesis. Read more »

12:10 AM | “You’ll Do”: Lack of Choosiness in Female Strawberry Poison Dart Frogs
Mate choice is one of the most well-studied aspects of evolution. To prove that they’re worth the effort, animals will do just about anything. They dance, prance, sing, bellow, and fight for attention. When you look around the animal kingdom, the wild results of mate choice boldly stand out, from the impractically beautiful tails of [...]

7:07 PM | Parasitic wasps use calcium pump to block fruit-fly immunity
A parasitic wasp on the prowl for fruit fly larva to inject with her eggs. By Carol ClarkParasitic wasps switch off the immune systems of fruit flies by draining calcium from the flies’ blood cells, a finding that offers new insight into how pathogens break through a host’s defenses.“We believe that we have discovered an important component of cellular immunity, one that parasites have learned to take advantage of,” says Emory University biologist Todd Schlenke, whose lab led the […]

6:40 PM | Shale Gas Fracking Has No Impact on Groundwater in Arkansas, Study Concludes
A new study by scientists at Duke University and the U.S. Geological Survey (USGS) finds no evidence of groundwater contamination from shale gas production in Arkansas. “Our results show no discernible impairment of groundwater quality in areas associated with natural gas drilling and hydraulic fracturing in this region,” said Avner Vengosh, professor of geochemistry and water quality at Duke’s Nicholas School of the Environment.

11:00 AM | Tit-for-Tat: A Bacterial Counterattack System
Microbial ecology may be a young field but it is well understood already that there is a broad spectrum of interactions between bacterial species, ranging from cooperative to competitive. In a recent paper researchers from John Mekalanos’ lab further characterized a recently discovered mechanism for inter-cell communication. This system, called the Type VI secretion system (T6SS), is a multi-protein complex native to many bacterial strains and structurally and functionally similar to a […]
