In a paper in this months PLoS Medicine, researchers from the Genome Institute of Singapore describe the identification of a human cellular protein that has a significant effect on the replication efficiency of Hepatitis B virus. Lisa F. P. Ng and colleagues found the protein--hnRNPK--when they noted an association between one particular sequence in the Hepatitis B virus and high levels of the virus in some infected patients. They discovered that how well the virus replicated is determined by a combination of sequence differences of the virus and how well hnRNPK binds to the viral DNA.
Hepatitis B is a serious global public health problem; more than 350 million people have lifelong infections. Chronically infected people are at high risk of death from cirrhosis of the liver and liver cancer, which both kill about 1 million people each year. Current antiviral therapies include lamivudine and alpha-interferon which also suppress viral replication by attacking the virus itself, but the identification of the action of this protein offers new therapeutic opportunities by targeting the human proteins that help the virus to replicate.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
