Nothing is more frustrating that watching that hourglass in the center of your screen while you wait for your computer to load a program or access the data you need.  

Well, maybe status bars are worse. Those used to be a culture war in the political science community.

A team from the Universities of Sheffield and Leeds may have found a way to speed things up: sound.  The paper in Applied Physics Letters finds that certain types of sound waves can move data quickly, using minimal power.

The hepatitis A virus can trigger acute liver inflammation which generally has a mild course in small children but which can become dangerous in adults. The virus, which is found worldwide, has previously been considered to be a purely human pathogen which at most is found in isolated cases in non-human primates.

Now an international team of researchers under the direction of the University of Bonn has now discovered in a large-scale study with nearly 16,000 specimens from small mammals from various continents that the hepatitis A virus - like HIV or Ebola as well - is of likely animal origin.

Standing for at least one-quarter of the day has been linked to lower odds of obesity, finds a new survey in Mayo Clinic Proceedings. But don't tell all those waitresses with sore backs and varicose veins.

Inflammatory processes sound bad, but they actually occur to promote healing after injury. However, when too active, these inflammatory processes can damage the body and perhaps contribute to heart disease.

Stress is a contributor to inflammation in the body. So is sleep disturbance, according to some, and insomnia, one of the most common sleep disorders, is correlated with increased risk for depression, medical comorbidities, and mortality. A new study in Biological Psychiatry reports that treatment for insomnia, either by cognitive behavioral therapy or the movement meditation tai chi, reduces inflammation levels in older adults over 55 years of age.

Pregnant women and new mothers are inundated with messages regarding the benefits of exclusive breastfeeding for babies in the first year of life and if you don't do that, shame on you for giving your child asthma, food allergies and eczema.

Astronomers have discovered an adolescent protostar that is undergoing a rapid-fire succession of growth spurts. Evidence for this fitful youth is seen in a pair of intermittent jets streaming away from the star's poles.

Known as CARMA-7, the protostar is one of dozens of similar objects in the Serpens South star cluster, which is located approximately 1,400 light-years from Earth. This clutch of nascent stellar objects was first detected by and named for the Combined Array for Research in Millimeter-wave Astronomy (CARMA) telescope.
