Mystery deepens in coffin-within-a-coffin found at Richard III site
A medieval stone coffin found at Grey Friars contains an inner lead coffin -- which archaeologists will now examine at the University of Leicester.

Molecular robots can help researchers build more targeted therapeutics
Many drugs such as agents for cancer or autoimmune diseases have nasty side effects because while they kill disease-causing cells, they also affect healthy cells.

Oregon team charts new understanding of actin filament growth in cells
University of Oregon biochemists have determined how tiny synthetic molecules disrupt an important actin-related molecular machine in cells in one study and, in a second one, the crystal structure of that machine when bound to a natural inhibitor.

Breakthrough in detecting DNA mutations could help treat tuberculosis, cancer
Researchers at the University of Washington and Rice University have developed a new method that can look at a specific segment of DNA and pinpoint a single mutation, which could help diagnose and treat diseases such as cancer and tuberculosis.

Statins suppress rett syndrome symptoms in mice
Statins, a class of cholesterol-lowering drugs found in millions of medicine cabinets, may help treat Rett Syndrome, according to a study published today in Nature Genetics.

New knowledge about permafrost improving climate models
New research findings from the Centre for Permafrost at the Department of Geosciences and Natural Resource Management, University of Copenhagen, document that permafrost during thawing may result in a substantial release of carbon dioxide into the atmosphere and that the future water content in the soil is crucial to predict the effect of permafrost thawing.

Water molecules control inactivation and recovery of potassium channels
Just 12 molecules of water cause the long post-activation recovery period required by potassium ion channels before they can function again.

Speed limit set for ultrafast electrical switch
Researchers from the US Department of Energy's SLAC National Accelerator Laboratory have clocked the fastest-possible electrical switching in magnetite, a naturally magnetic mineral.

Coronary artery disease continues to be neglected in women, despite it killing at least as many women as men
Despite coronary artery disease (CAD) killing at least as many women as men each year, women are still today less likely to receive preventive recommendations, such as lipid-lowering therapy, aspirin, and lifestyle advice, than are men at a similar risk level.
