Most of the 350 million facebook users around the world spend more time searching for specific content than aimlessly browsing news feeds or friends lists, according to research conducted at the University of Missouri School of Journalism.

Researchers have dubbed the practices "social searching" and "social browsing."

 People engage in social searching when navigating facebook in search of certain information about a specific person, group, or event; users engage in social browsing, on the other hand, when surveying the general landscape, such as their newsfeed or wall, without looking for specific information.

Immunization against "swine flu" in 1976 might have partially protected some individuals from the 2009 pandemic H1N1 influenza virus, according to a new study in Clinical Infectious Diseases.

Researchers found that individuals who reported receiving the 1976 vaccine mounted an enhanced immune response against both the 2009 pandemic H1N1 virus and a different H1N1 flu strain that circulated during the 2008-09 flu season.

It is unclear if the response was enough to protect against the 2009 H1N1 virus, but the study points to a lingering benefit. The findings also raise hope that those vaccinated against the 2009 H1N1 pandemic strain might also enjoy a similar long-term advantage.

Sermeq Kujalleq - Jakobshavn Isbrae Retreat

The Jakobshavn Isbrae, or Jakobshavn glacier, now becoming known by its local name - Sermeq Kujalleq - has been observed retreating since about 1851.


Near the small town of Ilulissat, formerly Jakobshavn, Sermeq Kujalleq is the Northern hemisphere's largest glacier with an outlet to the sea.  It drains about 6.5% of Greenland's ice sheet. The ice stream's contribution to sea level rise is about 0.06 millimeters - about 0.002 inches - per year, roughly 4% of the 20th century rate of sea level increase.
