First Atomic-Scale Real-Time Movies of Platinum Nanocrystal Growth in Liquids
Berkeley Scientists Create Graphene Liquid Cells for Electron Microscopy Studies of Nanocrystal Formation
They won’t be coming soon to a multiplex near you, but movies showing the growth of platinum nanocrystals at the atomic-scale in real-time have blockbuster potential. A team of scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley has developed a technique for encapsulating liquids of nanocrystals between layers of graphene so that chemical reactions in the liquids can be imaged with an electron microscope. With this technique, movies can be made that provide unprecedented direct observations of physical, chemical and biological phenomena that take place in liquids on the nanometer scale. (more…)
Political Leaders Play Key Role in How Worried Americans Are By Climate Change
COLUMBUS, Ohio – More than extreme weather events and the work of scientists, it is national political leaders who influence how much Americans worry about the threat of climate change, new research finds.
In a study of public opinion from 2002 to 2010, researchers found that public belief that climate change was a threat peaked in 2006-2007 when Democrats and Republicans in Congress showed the most agreement on the issue. (more…)
Caltech-led Researchers Measure Body Temperatures of Dinosaurs for the First Time
*Some Dinosaurs Were as Warm as Most Modern Mammals*
PASADENA, Calif.—Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold or warm blooded. When dinosaurs were first discovered in the mid-19th century, paleontologists thought the y were plodding beasts that had to rely on their environments to keep warm, like modern-day reptiles. But research during the last few decades suggests that they were faster creatures, nimble like the velociraptors or T. rex depicted in the movie Jurassic Park, requiring warmer, regulated body temperatures like in mammals.
Now, a team of researchers led by the California Institute of Technology (Caltech) has developed a new approach to take body temperatures of dinosaurs for the first time, providing new insights into whether dinosaurs were cold or warm blooded. By analyzing isotopic concentrations in teeth of sauropods, the long-tailed, long-necked dinosaurs that were the biggest land animals to have ever lived—think Apatosaurus (also known as Brontosaurus)—the team found that the dinosaurs were about as warm as most modern mammals.

Scientists identify key enzyme in microbial immune system
Imagine a war in which you are vastly outnumbered by an enemy that is utterly relentless – attacking you is all it does. The intro to another Terminator movie? No, just another day for microbes such as bacteria and archaea, which face a never-ending onslaught from viruses and invading strands of nucleic acid known as plasmids.
