New research suggests for the first time that frequent bouts of sporadic activity could be just as beneficial to children's health as longer exercise sessions. A team from the University of Exeter measured the frequency, intensity and duration of bouts of physical activity in a group of children and analysed the results against a number of health indicators. http://www.physorg.com/news161257903.html Medicine & Health Mon, 11 May 2009 10:52:16 EST news161257903 (PhysOrg.com) -- As the 2008-09 Antarctic drilling season concludes, the IceCube Neutrino Observatory is on track to be finished as planned in 2011. http://www.physorg.com/news154792355.html Physics Wed, 25 Feb 2009 13:53:19 EST news154792355 Gamma-ray bursts are by far the brightest and most powerful explosions in the Universe, second only to the Big Bang itself. So it might seem a bit surprising that a group of them has gone missing. http://www.physorg.com/news143986294.html Space & Earth Thu, 23 Oct 2008 13:11:34 EST news143986294 For decades it was baffling. Out of the still night sky, astronomers peering through their telescopes would occasionally glimpse quick bursts of high-energy light popping off like flashbulbs at the far side of the universe. http://www.physorg.com/news143816869.html Space & Earth Tue, 21 Oct 2008 14:07:49 EST news143816869 (PhysOrg.com) -- Gamma-ray bursts, powerful glares of high-energy that wash through the Universe once every day or so are, for a brief time, the brightest objects in the gamma-ray sky. ESA`s Integral gamma-ray observatory has observed several low-luminosity gamma-ray bursts, confirming the existence of an entire population of weaker bursts hardly noticed so far. http://www.physorg.com/news143119977.html Space & Earth Mon, 13 Oct 2008 12:32:57 EST news143119977 (PhysOrg.com) -- While only on orbit for 40 days and still in the process of a two-month checkout, NASA's Gamma-ray Large Area Telescope (GLAST) has already detected 12 powerful gamma-ray bursts, an encouraging harbinger of good things to come for this mission. The gamma-ray bursts were detected by the GLAST Burst Monitor (GBM), one of two instruments on the spacecraft. http://www.physorg.com/news136564049.html Space & Earth Tue, 29 Jul 2008 15:27:29 EST news136564049
