Posted: 04 Jul 2014 10:46 AM PDT

The High Energy Stereoscopic System telescope in Namibia has detected gamma rays of only 30 Giga electron volts (GeV) from the Vela pulsar. This is the first pulsar to be detected by HESS and the second - after Crab in 2011- to be spotted by ground-based gamma ray telescopes.

A new report, Technological Breakthroughs for Scientific Progress, has been published today by the European Science Foundation. The five Overwhelming Drivers identified in this exercise are to reduce mass, maintain stiffness; Build a spacecraft and missions that can last 50 years; Deploy a 30m+ telescope into space; Enable humans to stay in space for more than 2 years; Autonomous geophysical survey of planets.

Finding real value in big data for public health

Posted: 02 Jul 2014 09:24 AM PDT

Media reports of public health breakthroughs from big data have been largely oversold, according to a new study. But don't throw away that data just yet. The authors maintain that the promise of big data can be fulfilled by tweaking existing methodological and reporting standards. In the study, the research team demonstrate this by revising the inner plumbing of the Google Flu Trends (GFT) digital disease surveillance system, which was heavily criticized last year (see here and here) after producing erroneous forecasts.
