The GOES-13 satellite captured images of the powerful weather system that triggered severe weather in the southern U.S. this weekend, and NASA created an animation to show its progression. GOES-13 satellite data showed the strong cold front as it moved eastward from Saturday through Monday and generated tornadoes before moving off-shore into the Atlantic Ocean. NASA's Aqua satellite also captured data from the system and took the temperature of the cold front's cloud tops and revealing severely cold temperatures of some of the thunderstorms.

CINCINNATI – A new biomarker-based diagnostic test is more effective than the current best practice for early detection of adverse outcomes after acute kidney injury (AKI), which can be fatal for an estimated 50 percent of the critically ill patients who get the condition.
Dietary and lifestyle changes significantly reduce elevated triglycerides (a type of blood fat) — which is associated with heart, blood vessel and other diseases — according to an American Heart Association scientific statement
Changes such as substituting healthy, unsaturated dietary fats for saturated ones, engaging in physical activity and losing excess weight can decrease triglycerides by 20 percent to 50 percent, according to the statement's authors. The statement is published in Circulation: Journal of the American Heart Association.
Surgical patients with do-not-resuscitate (DNR) orders appear to be at higher risk for poor surgical outcomes, according to a report published online today by the Archives of Surgery, one of the JAMA/Archives journals. The study will appear in the August print issue of the journal.
Excessive alcohol consumption appears to be associated with changes in some surgical skills performed on virtual reality simulator testing the following day, according to a report in the April issue of Archives of Surgery, one of the JAMA/Archives journals.
Airway abnormalities were uncommon among well-appearing infants hospitalized with apparent life-threatening events, and pediatric otolaryngology service was involved in their care only a small proportion of the time during five years after the episode, according to a report in the April issue of Archives of Otolaryngology – Head & Neck Surgery, one of the JAMA/Archives journals.
AMES, Iowa – When your family members gather at a picnic in your backyard, there may be 10 to 20 people -- maybe more -- enjoying your barbecue.
When flies visit your party, be glad they don't bring their entire family.
Houseflies have more than 152,000 cousins. And those are just the ones we know about.
An Iowa State University researcher is one of a team of scientists who have recently researched the fly family tree -- one of the most complicated in the animal world.
BOSTON--High-grade serous ovarian cancer (HGSOC), the fifth-deadliest cancer among American women, is thought by many scientists to often be a fallopian tube malignancy masquerading as an ovarian one. While most of the evidence linking HGSOC to the fallopian tubes has so far been only circumstantial, a new Dana-Farber Cancer Institute study suggests there is a direct connection, a finding that could aid in the development of better treatments for the cancer.
Medical researchers today held out promise that a simple injection is being developed to limit the devastating consequences of heart attacks and strokes.
Described by the lead researcher as 'a fascinating new achievement', work has already begun to translate the research into novel clinical therapies.
The University of Leicester led an international team whose research has been published today in the Early Online Edition of the Proceedings of the National Academy of Sciences (PNAS).
OTTAWA, ONTARIO, CANADA — Canada needs to modernize its pharmaceutical drug laws to ensure that new drugs as well as older drugs are safe for Canadians, states an editorial in CMAJ (Canadian Medical Association Journal) http://www.cmaj.ca/cgi/doi/10.1503/cmaj.110489.
Active efforts are required to preserve biodiversity in the seas – that far most people are in agreement. But in our enthusiasm to save uncommon species, we sometimes miss the common species that form the basis of marine ecosystems. 'Change strategy' is the challenge to the authorities from researchers at the University of Gothenburg, Sweden.
A new study of older diabetes patients has found that well-controlled blood sugar levels were associated with a lower risk of major complications such as heart attacks, amputation and kidney disease, but the very lowest blood sugar levels were associated with a small but significant increased risk of death. The study published in the June 2011 issue of the journal Diabetes Care, followed more than 70,000 type 2 diabetes patients from Kaiser Permanente who were over 60 years of age for four years.
Animals and plants may need extra habitats to survive the challenge of climate change, according to research by scientists at the University of York.
Human activities have reduced natural habitats to isolated "islands", making it more difficult for some species to re-locate to cooler regions in response to their existing locations growing warmer.
PROVIDENCE, R.I. [Brown University] — Adolescents who believe they matter to their families are less likely to threaten or engage in violence against family members, according to a new study led by Brown University sociologist Gregory Elliott. The research s published in the Journal of Family Issues.
COLUMBIA, Mo. – University of Missouri researchers believe both man and animal will benefit from their discovery that the same gene mutation found in Tibetan Terrier dogs can also be found in a fatal human neurological disorder related to Parkinson's disease.
