Kinks and curves at the nanoscale
(University of Vermont) Since 2004, materials scientists and nanotechnology experts have been excited about a special of arrangement of atoms called a "coherent twin boundary" that can add enormous strength to metals like gold and copper. The CTBs are described as "perfect," appearing like a one-atom-thick plane in models and images. New research shows that these boundaries are not perfect. Even more surprising, the newly discovered kinks and defects appear to be the cause of the CTB's strength.
RNA capable of catalyzing electron transfer on early earth with iron's help, study says
(Georgia Institute of Technology) A new study shows how complex biochemical transformations may have been possible under conditions that existed when life began on the early Earth. The study shows that RNA is capable of catalyzing electron transfer under conditions similar to those of the early Earth.
NASA's STEREO detects a CME from the sun
(NASA/Goddard Space Flight Center) On 5:24 a.m. EDT on May 17, 2013, the sun erupted with an Earth-directed coronal mass ejection or CME, a solar phenomenon that can send billions of tons of solar particles into space that can reach Earth one to three days later and affect electronic systems in satellites and on the ground.
Attacking MRSA with metals from antibacterial clays
(Arizona State University) Shelley Haydel, a researcher at Arizona State University's Biodesign Institute has a new approach to developing effective, topical antibacterial agents -- one that draws on a naturally occurring substance recognized since antiquity for its medicinal properties: clay.
Study identifies new approach to improving treatment for MS and other conditions
(University of California - Davis Health System) Working with lab mice models of multiple sclerosis (MS), UC Davis scientists have detected a novel molecular target for the design of drugs that could be safer and more effective than current FDA-approved medications against MS.
First Atlanta Science Festival set for 2014
(Georgia Institute of Technology) Atlanta residents of all ages will celebrate the science and technology of the region and its impact on our daily lives during the inaugural Atlanta Science Festival, March 22-29, 2014. With scientists, engineers and educators from local museums, corporations, K-12 schools and universities, the festival will host more than 40 different events for children and adults at venues across the city.
UCSB assistant professor Michelle O'Malley receives 2013 DOE Early Career Award
(University of California - Santa Barbara) Michelle O'Malley, an assistant professor in UC Santa Barbara's Department of Chemical Engineering, has received a 2013 Early Career Award by the US Department of Energy's Office of Science. O'Malley is among 61 recipients of the annual research award, chosen from a pool of approximately 770 proposals.
SUMO wrestling cells reveal new protective mechanism target for stroke
(University of Bristol) Scientists investigating the interaction of a group of proteins in the brain responsible for protecting nerve cells from damage have identified a new target that could increase cell survival.
Promising doped zirconia
(Springer) Materials belonging to the family of dilute magnetic oxides are good candidates for spintronics applications. Davide Sangalli of the Microelectronics and Microsystems Institute at the National Research Council, Agrate Brianza, Italy, and colleagues explored the effect of iron doping on thin films of a material called zirconia. For the first time, the authors bridged the gap between the theoretical predictions and the experimental measurements of this material, in a paper in EPJ B.
Now we know why old scizophrenia medicine works on antibiotics-resistant bacteria
(University of Southern Denmark) An old medicine for schizophrenia is effective at treating something completely different than it was designed for: antibiotic-resistant bacteria. So far it has been a mystery how this old schizophrenia medicine works, but now researchers from the University of Southern Denmark have figured it out. This can lead to a new medicine against the increasingly threatening antibiotic-resistant bacteria.
