NASA and the Air Force Office of Scientific Research, or AFOSR, have successfully launched a small rocket using an environmentally-friendly, safe propellant comprised of aluminum powder and water ice, called ALICE.
NASA satellites continue to capture important wind speed and cloud data that forecasters at the National Hurricane Center are using to help their forecasts. QuikScat has been particularly helpful in determining the extent of hurricane and tropical storm-force winds, and they go a great distance.
(PHILADELPHIA) -- The nation's home foreclosure epidemic may be taking its toll on Americans' health as well as their wallets.
WASHINGTON, Aug. 18, 2009 -- In a first-of-its kind study, scientists reported today at the 238th National Meeting of the American Chemical Society (ACS) that snack foods like popcorn and many popular breakfast cereals contain "surprisingly large" amounts of healthful antioxidant substances called "polyphenols."
PHILADELPHIA -- Patients who experience fatigue during radiotherapy for breast or prostate cancer may be reacting to activation of the proinflammatory cytokine network, a known inflammatory pathway, according to a report in Clinical Cancer Research, a journal of the American Association for Cancer Research.
Quantum mechanics and Einstein's theory of general relativity are both extremely accurate theories of how the universe works, but all attempts to combine the two into a unified theory have ended in failure.
PHILADELPHIA -- "A biologist, a physicist, and a nanotechnologist walk into a ..." sounds like the start of a joke. Instead, it was the start of a collaboration that has helped to decipher a critical, but so far largely unstudied, phase of how cells divide.
PHILADELPHIA -- A tissue-repair-and-regeneration pathway in the human body, including wound healing, is essential for the early lung to develop properly. Genetically engineered mice fail to develop lungs when two molecules in this pathway, Wnt2 and Wnt2b, are knocked out. The findings are described this week in Developmental Cell.
Honeybees in colonies affected by colony collapse disorder (CCD) have higher levels of pathogens and are co-infected with a greater number of pathogens than their non-CCD counterparts, but no individual pathogen can be singled out as the cause of CCD, according to a study by an international team of researchers.

In a study published this month in the Journal of Food Science, scientists from The Hershey Company and Brunswick Laboratories (Norton, MA) showed that over 85% of the cocoa flavanols were preserved in recipes for chocolate frosting, hot cocoa drink and chocolate cookies.
Three young adults who received gene therapy for a blinding eye condition remained healthy and maintained previous visual gains one year later, according to an August online report in Human Gene Therapy. One patient also noticed a visual improvement that helped her perform daily tasks, which scientists describe in an Aug.
(PHILADELPHIA) -- Breast cancer survivors who lift weights are less likely than their non-weightlifting peers to experience worsening symptoms of lymphedema, the arm- and hand-swelling condition that plagues many women following surgery for their disease, according to new University of Pennsylvania School of Medicine research published in the August 13 issue of the New England Journal of M
GAINESVILLE, Fla. -- Scientists have discovered that even in adults born with extremely impaired sight, the brain can rewire itself to recognize sections of the retina that have been restored by gene therapy.
PHILADELPHIA -- One year after a trio of young adults received gene therapy for an inherited form of blindness, researchers have documented that the patients are still experiencing the same level of remarkable vision improvements previously measured within weeks.
For many Americans who live on the Atlantic coast, Andrew, Ivan and Katrina are more than just names--they are reminders of the devastating impact of cyclonic activity in the region during hurricane season. If it seems like hurricane seasons have been more active in recent years, you're on to something.
