  • NASA orbiter spots carbon dioxide snowflakes on Mars
    NASA's Mars Reconnaissance Orbiter has found carbon dioxide snowflakes on the Red Planet, which makes it the only entity in the solar system known to have such weather. Scientists attest that the snow came from clouds around the south pole of Mars during Martian winter in 2006 and 2007. They expect the discovery will help them explain how the phenomenon develops and persists. Space.com (9/14) LinkedInFacebookTwitterEmail this Story

  • Curiosity captures partial solar eclipse on Mars
    Images of a brief partial solar eclipse on Mars were taken by NASA's Curiosity rover on Thursday using its Mast Camera. The images can aid researchers in understanding the evolution of the orbits of the Red Planet's moons Phobos and Deimos. Space.com (9/17) LinkedInFacebookTwitterEmail this Story
  • NASA delays Endeavour's journey due to thunderstorms
    NASA confirmed that the arrival of space shuttle Endeavour at the Los Angeles International Airport will be moved to Friday due to possible thunderstorms. The shuttle was originally set to leave the Kennedy Space Center in Florida for Houston early Monday before heading to Los Angeles. Los Angeles Times/L.A.

  • Subconscious signals could modify people's response to treatment
    Subconscious cues such as sights, sounds and smells can subtly change the way people respond to medical treatment, according to a study in the journal Proceedings of the National Academy of Sciences. Researchers examined the idea by showing two different images to participants coinciding with the volunteers receiving varying level of heat pulse to their arm. "The placebo response is emerging as an excellent model to understand how our brain works," said Fabrizio Benedetti of the University of Turin Medical School in Italy.

  • Neurons' shape plays a role in human brain's development
    The shape of neurons plays an essential role in the development of the human brain, according to a study in the journal Proceedings of the National Academy of Sciences. Researchers including Henry Markram, a neural microcircuitry professor at the Swiss Federal Institute of Technology, have created three-dimensional computer models of the somatosensory cortex of a rat that does not contain signalling chemicals, thought to be important in the way neurons select others they connect to. They expect the findings to help uncover the etiology of health conditions such as schizophrenia. New Scientist (9/17) LinkedInFacebookTwitterEmail this Story
 
  • Extracellular matrix helps stem cells regrow muscle
    Marine Sgt. Ron Strang, whose left thigh was damaged by a bomb in Afghanistan, was able to walk normally again after the implantation of extracellular matrix that helped him regrow muscle. The matrix was developed from pig tissue and breaks down in the body, where it directs a patient's stem cells to start to build muscle. Strang is one of the first patients in a trial that aims to eventually treat 80 people. The New York Times (tiered subscription model) (9/16) LinkedInFacebookTwitterEmail this Story
  • Large Roman poolside mosaic discovered in Turkey
    Researchers have uncovered a 1,600-square-foot poolside mosaic of intricate geometric patterns in the southern region of Turkey. The discovery, which dates to the third or fourth century, suggests the far-reaching influence of the Romans on the the city of Antiochia ad Cragum, established in the first century and known for having Roman features such as markets and bathhouses.

  • NASA grants funding for Thor-inspired initiative
    NASA awarded a $100,000 grant from its Innovative Advanced Concepts project to Tethers Unlimited's NanoTHOR initiative, which aims to use tethers to link nanosatellites to upper rocket stages. The idea is similar to the power of Norse-inspired superhero Thor, who can throw and swirl his hammer at fast speeds. "Using a few tricks, we could get that system spinning so the rocket upper stage could swing the nanosatellite out of Earth's orbit and on to the moon or an interplanetary trajectory," said Robert Hoyt, CEO and chief scientist of Tethers Unlimited.
