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.

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?

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
