An analysis of patented university inventions licensed to biotechnology firms has revealed early bottlenecks on the path to commercialization. To open these roadblocks, the researchers suggest that better communication of basic research results during the discovery stage could lead to faster commercialization down the road.
Seismic events aren’t rare occurrences on Antarctica, where sections of the frozen desert can experience hundreds of micro-earthquakes an hour due to ice deformation. Some scientists call them icequakes. But in March of 2010, the ice sheets in Antarctica vibrated a bit more than usual because of something more than 3,000 miles away: the 8.8-magnitude Chilean earthquake. A new Georgia Institute of Technology study published in Nature Geoscience is the first to indicate that Antarctica’s frozen ground is sensitive to seismic waves from distant earthquakes.
