In collaboration with staff from the Argonne Leadership Computing Facility, researchers at the National Cancer Institute have perfected a technique that accurately computes the 3-D structure of RNA sequences. This method, which relies on a computer program known as RS3D and supercomputer Mira gives researchers studying cancer and other diseases structural insights about associated RNAs that can be used to advance computer-assisted drug design and development.

In a first-of its kind study, researchers from the Icahn School of Medicine at Mount Sinai found an elevated risk of intellectual disability (ID) in children born to mothers treated with antidepressants, but the risk was not statistically significant and is likely due to other factors, including parental age and the parents’ psychiatric history.

New biological information gleaned from the red vizcacha rat, a native species of Argentina, demonstrates how genomes can rapidly change in size. Researchers from McMaster University set out to study this particular species because its genome, or its complete set of DNA, is the largest of all mammals, and appears to have increased in size very rapidly.

In a milestone for studying a class of chemical reactions relevant to novel solar cells and memory storage devices, an international team of researchers working at the Department of Energy’s SLAC National Accelerator Laboratory used an X-ray laser to watch “molecular breathing” – waves of subtle in-and-out motions of atoms – in real time and unprecedented detail.

To paraphrase the classic poem, no hair is an island entire of itself. Instead, University of California, Irvine scientists have discovered that all hairs can communicate with each other and grow in coordination across the entire body. This is regulated by a single molecular mechanism that adjusts by skin region to ensure efficient hair growth – so no bald patches form – and enable distinct hair densities in different body areas.

For the subset of women with BRCA mutations who have already had ovarian cancer, risk-reducing mastectomy might not be worth the price tag. New research from the Duke Cancer Institute finds that for many women in this unique group, prophylactic mastectomy does not produce a substantial survival gain versus breast cancer screening alone and is not cost-effective.

Sometimes, liquid drops don't drop. Instead, they climb. Using computer simulations, researchers have now shown how to induce droplets to climb stairs all by themselves. This stair-climbing behavior could be useful in everything from water treatment and new lab-on-a-chip microfluidic devices, to biochemical processing and medical diagnostic tools. The researchers describe their findings this week in the journal Physics of Fluids.

A study by researchers at the University of Chicago Medicine shows that when mice that are genetically susceptible to developing inflammatory bowel disease (IBD) were given antibiotics during late pregnancy and the early nursing period, their offspring were more likely to develop an inflammatory condition of the colon that resembles human IBD.

Bugs in your eyes may be a good thing. Resident microbes living on the eye are essential for immune responses that protect the eye from infection, new research shows. The study, which appears in the journal Immunity on July 11, demonstrates the existence of a resident ocular microbiome that trains the developing immune system to fend off pathogens. The research was conducted at the National Eye Institute (NEI), part of the National Institutes of Health.
