| Unprecedented control of genome editing in flies promises insight into human development, disease Posted: 23 Aug 2013 01:38 PM PDT In an era of widespread genetic sequencing, the ability to edit and alter an organism's DNA is a powerful way to explore the information within and how it guides biological function.  |
| Sea ice decline spurs the greening of the Arctic Posted: 23 Aug 2013 06:43 AM PDT Sea ice decline and warming trends are changing the vegetation in nearby arctic coastal areas, according to scientists.  |
| Posted: 23 Aug 2013 06:13 AM PDT When the teen drivers listened to their preferred music, virtually all (98 percent) demonstrated an average of three deficient driving behaviors in at least one of the trips. Nearly a third of those (32 percent) required a a sudden verbal warning or command for action, and 20 percent needed an assisted steering or braking maneuver to prevent an imminent accident. These errors included speeding, tailgating, careless lane switching, passing vehicles and one-handed driving.  |
| A fluffy disk around a baby star Posted: 23 Aug 2013 06:11 AM PDT Astronomers have observed a disk around the young star RY Tau (Tauri). The team's analysis of the disk shows that a "fluffy" layer above it is responsible for the scattered light observed in the infrared image. Detailed comparisons with computer simulations of scattered light from the disk reveal that this layer appears to be a remnant of material from an earlier phase of stellar and disk development, when dust and gas were falling onto the disk.  |
