| Mach 1000 shock wave lights supernova remnant Posted: 25 Nov 2013 01:48 PM PST When a star explodes as a supernova, the material blasted outward from the explosion still glows hundreds or thousands of years later, forming a picturesque supernova remnant. What powers such long-lived brilliance? In the case of Tycho's supernova remnant, astronomers have discovered that a reverse shock wave racing inward at Mach 1000 (1,000 times the speed of sound) is heating the remnant and causing it to emit X-ray light.  |
| Search for habitable planets should be more conservative, experts say Posted: 25 Nov 2013 01:46 PM PST Scientists should take the conservative approach when searching for habitable zones where life-sustaining planets might exist, according to experts.  |
| Swarming insect provides clues to how the brain processes smells Posted: 25 Nov 2013 01:42 PM PST Our sense of smell is often the first response to environmental stimuli. Odors trigger neurons in the brain that alert us to take action. However, there is often more than one odor in the environment, such as in coffee shops or grocery stores. How does our brain process multiple odors received simultaneously?  |
| Materialism makes bad events even worse Posted: 25 Nov 2013 09:55 AM PST Materialism makes negative outcomes even worse, according to research.  |
| Pill-popping galaxy hooked on gas Posted: 25 Nov 2013 07:12 AM PST Our Galaxy may have been swallowing "pills" -- clouds of gas with a magnetic wrapper -- to keep making stars for the past eight billion years.  |
| Dying from food allergy less likely than being murdered Posted: 25 Nov 2013 06:15 AM PST A person with a food allergy is more likely to be murdered than to die from a severe reaction, according to a new study.  |
| Water-based imaging maps brain neurons before surgery Posted: 21 Nov 2013 03:42 PM PST Some neurosurgeons are using a new approach to visualize the brain's delicate anatomy prior to surgery. The novel technique allows neurosurgeons to see the brain's nerve connections thus preserving and protecting critical functions such as vision, speech and memory. No needles, dyes or chemicals are needed to create the radiology scan. The main imaging ingredient? Water.  |
| Mouse study finds gut microorganisms may determine cancer treatment outcome Posted: 21 Nov 2013 12:49 PM PST An intact population of microorganisms that derive food and benefit from other organisms living in the intestine is required for optimal response to cancer therapy, according to a mouse study.  |
