| Learn that tune while fast asleep: Stimulation during sleep can enhance skill learning Posted: 24 Jun 2012 10:50 AM PDT Want to nail that tune that you've practiced and practiced? Maybe you should take a nap with the same melody playing during your sleep, new provocative research suggests. The research grows out of exciting existing evidence that suggests that memories can be reactivated during sleep and storage of them can be strengthened in the process.  |
| Significant sea-level rise in a two-degree warmer world Posted: 24 Jun 2012 10:49 AM PDT Even if global warming is limited to two degrees Celsius, global mean sea level could continue to rise, reaching between 1.5 and four meters above present-day levels by the year 2300, with the best estimate being at 2.7 meters, according to a new study. However, emissions reductions that allow warming to drop below 1.5 degrees Celsius could limit the rise strongly.  |
| New deglaciation data opens door for earlier First Americans migration Posted: 21 Jun 2012 11:13 AM PDT A new study of lake sediment cores from Sanak Island in the western Gulf of Alaska suggests that deglaciation there from the last Ice Age took place as much as 1,500 to 2,000 years earlier than previously thought, opening the door for earlier coastal migration models for the Americas.  |
| Dog-associated house dust protects against respiratory infection linked to asthma Posted: 19 Jun 2012 07:57 PM PDT House dust from homes with dogs appears to protect against infection with a common respiratory virus that is associated with the development of asthma in children.  |
