NIST Ytterbium Atomic Clocks Set Record for Stability

Posted: 22 Aug 2013 02:13 PM PDT

A pair of experimental atomic clocks based on ytterbium atoms at the National Institute of Standards and Technology (NIST) has set a new record for stability. The clocks act like 21st-century pendulums or metronomes that could swing back and forth with perfect timing for a period comparable to the age of the universe.

New Technique May Help Regenerate Heart Cells to Treat Heart Disease

Posted: 22 Aug 2013 11:26 AM PDT

Researchers have developed a new technique that might one day be used to convert cells from heart disease patients into heart muscle cells that could act as a personalized treatment for their condition. The research is published online on August 22 in the journal of the International Society of Stem Cell Research, Stem Cell Reports, published by Cell Press.

Study reveals how SARS virus hijacks host cells

Posted: 22 Aug 2013 08:40 AM PDT

UC Irvine infectious disease researchers have uncovered components of the SARS coronavirus – which triggered a major outbreak of severe acute respiratory syndrome in 2002-03 – that allow it to take over host cells in order to replicate.

This insight is critical for a full understanding of any outbreaks caused by such viruses and may prove beneficial in the development of therapies not only for human coronavirus infections but for other pathogenic illnesses as well. Study results appear online in the July/August issue of mBio.

Well-being not a priority for workaholics, researcher says

Working overtime may cost you your health, according to a Kansas State University doctoral researcher.

Two Studies Identify Potential New Drug for Crohn’s Disease and Ulcerative Colitis

Vedolizumab, a new intravenous antibody medication, has shown positive results for treating both Crohn’s disease and ulcerative colitis, according to researchers at the University of California San Diego, School of Medicine. The findings, published in two papers, will appear in the August 22 issue of the New England Journal of Medicine (NEJM).

Creating plants that make their own fertilizer

Posted: 22 Aug 2013 08:14 AM PDT

Since the dawn of agriculture people have exercised great ingenuity to pump more nitrogen into crop fields. Farmers have planted legumes and plowed the entire crop under, strewn night soil or manure on the fields, shipped in bat dung from islands in the Pacific or saltpeter from Chilean mines and plowed in glistening granules of synthetic fertilizer made in chemical plants.
