CDC today announced updates to its interim guidance for pre-pregnancy counseling and prevention of sexual transmission of Zika based on ongoing assessment of available data, primarily extending the timeframe for men with possible Zika exposure but no Zika symptoms to wait before attempting pregnancy with their partner and extending the time for use of condoms by these men to protect against sexual transmission of Zika virus infection.

The first Zika virus-related death in the continental U.S. occurred in June of this year, but even now, months later, two aspects of this case continue to puzzle health experts. First, why did this patient die? It is quite rare for a Zika infection to cause severe illness in adults, much less death. Second, how did another individual, who visited the first while in the hospital, become ill from Zika? This second patient did not do anything that was known at the time to put people at risk for contracting the virus.

Fat cells that amplify nerve signals in response to cold also affect blood sugar metabolism, researchers report

When exposed to cold, clusters of cells within the body’s white fat become beige — a color change that reflects the creation of more energy-producing mitochondria, cellular components that enable cells to burn calories and give off heat. But since white fat cells have very few nerves, how do beige fat cells get the message that it’s cold outside?

Noncoding mutations disrupt cooperative function of ‘gene families’ in rare genetic disorder

Scientists say they are one step closer to understanding the genetic mechanism of a rare, complex, multiple-gene disorder called Hirschsprung’s disease. Their results suggest that many patients develop the disease when multiple mutations in gene regulatory sequences of a specific gene combine to destroy the normal cooperative function of a whole network of genes.
