By observing visible “light echoes,” astronomers have assembled one of the first 3-D perspectives of a cosmic object. The new view of the supernova remnant Cassiopeia A confirms that it formed during a lopsided explosion.Astronomers see historical supernova from new angle
Most parts of the fruit fly brain, as well as the human brain, are devoid of neural stem cells, which means that once a nerve cell dies, it can't be replaced. A new study in fruit flies shows one way to keep these stem cells from disappearing as the brain matures.
When the Galileo probe descended through Jupiter's atmosphere in 1995, it found neon to be one-tenth as abundant as predicted. This unexpected finding has led two UC Berkeley researchers to propose that this is due to a rain of helium that depletes Jupiter's layers of neon as well as helium.
The Hubble Space Telescope has allotted an unprecedented 902 orbits of observing time to a project that will seek out distant supernovae and galaxies to study dark energy and galaxy evolution.
Eric Brewer, UC Berkeley professor of electrical engineering and computer sciences, is the 2009 recipient of the ACM-Infosys Foundation Award in the Computing Sciences, a prestigious honor that comes with a $150,000 prize.

Scientists have sequenced the genome of a weird creature that exists as an amoeba until the food runs out, then turns into a two-tailed swimmer to find new hunting grounds. The organism, called Naegleria, is an early eurkaryote ? a cell with a nucleus and internal organs ? and could shed light on the origin of complex cells like those in humans.
