Planets around stars are the rule rather than the exception

(January 11, 2012)

There are more exoplanets further away from their parent stars than originally thought, according to new astrophysics research. In a new paper appearing in the Jan. 12 edition of the journal, Nature, astrophysicist Kem Cook as part of an international collaboration, analyzed microlensing data that bridges the gap between a recent finding of planets further away from their parent stars and observations of planets extremely close to their parent star. The results point to more planetary systems resembling our solar system rather than being significantly different.

Lawrence Livermore National Laboratory, working with Loyola University, has won a $3.5 million grant from the National Institutes of Health to help develop a new anthrax vaccine. The grant is the first major NIH-funded biodefense grant focused on LLNL's nanolipoprotein technology, a potential breakthrough in vaccine development. Today, many vaccines are based on a single protein derived from a specific pathogen (bacterial, viral, fungal). The idea is that the body "sees" the protein as foreign and mounts an immune response to kill the invader, which keeps the body free from disease.

Fat turnover in obese slower than average

(September 23, 2011)

It may be more difficult for obese people to lose fat because the "turnover" rate is much slower for those overweight than average weight individuals. New research in the Sept. 25 online edition of the journal Nature shows that the turnover (storage and loss rate) of fat in the human body is about 1 1/2 years compared to fat cells, which turnover about every 10 years, according to Bruce Buchholz of Lawrence Livermore National Laboratory and one of the authors of the report.
