Operator storefronts and portals now account for just 6% of content downloads worldwide, with Google Play and Apple's App Store now comprising nearly 70% between them. The increasing popularity of OTT (Over The Top) stores had led to many operators closing their own mobile storefronts.
 

Fluoride is good but too much of anything can be bad. However, a filter system developed in India using a medicinal herb is very, very good.

The  divergent lineage of the oldest known genetic branch of the human Y chromosome, the hereditary factor determining male sex, has been pushed back in time.

The new divergent lineage, found in an individual who submitted his DNA to Family Tree DNA, a company specializing in DNA analysis to trace family roots, branched from the Y chromosome tree before the first appearance of anatomically modern humans in the fossil record.

Deleting a specific gene in mice prevents them from becoming obese  - even on a high fat diet, according to a  two-year study funded by the National Institutes of Health and the U.S. Department of Agriculture and published in the Journal of Lipid Research.

Each year more than 40 million Americans become sick with foodborne infections. Among those who become ill, 128,000 will be hospitalized and 3,000 will die. Foodborne illness also takes a toll on our economy: Broad estimates are that the US loses $77 billion in lost productivity due to people who become sick - adding in more estimates of economic impact a foodborne illness outbreak has on the affected industry.

Usually, a great deal of effort has gone into preventing foodborne illness outbreaks. In 2010, the Obama administration got the Food Safety Management Act passed but it hasn't been funded or implemented, though they have scuttled other food testing divisions of the government that have been focused on preventing contamination of food supply.

The gravitational field surrounding the massive cluster of galaxies called Abell 68 acts as a natural lens in space to brighten and magnify the light coming from very distant background galaxies.

Like a fun house mirror, lensing creates a fantasy landscape of arc-like images and mirror images of background galaxies. The foreground cluster is 2 billion light-years away, and the lensed images come from galaxies far behind it.

In this photo, the image of a spiral galaxy at upper left has been stretched and mirrored into a shape similar to that of a simulated alien from the classic 1970s computer game "Space Invaders!" A second, less distorted image of the same galaxy appears to the left of the large, bright elliptical galaxy.
