The Case Of The Neutron Star With A Wayward Wake May 31, 2006
A long observation with NASA’s Chandra X-ray Observatory revealed important new details of a neutron star that is spewing out a wake of high-energy particles as it races through space. The deduced location of the neutron star on the edge of a supernova remnant, and the peculiar orientation of the neutron star wake, pose mysteries that remain unresolved.
Researchers Pinpoint Causes Of Adverse Reactions To Popular Type 2 Diabetes Drugs
Used by several million people worldwide, rosiglitazone (RSG) is an oral agent that helps patients with type 2 diabetes to maintain good blood glucose levels by improving how their bodies use insulin.
Taking Soldiers Out Of Harm’s Way: Research On Unmanned Ground Vehicles Could Make Surveillance …
Over the past three years, thousands of American soldiers in Iraq have been horribly injured or killed by improvised explosive devices (IEDs). At Florida State University in Tallahassee, Fla., one researcher is working on new technologies that could reduce the carnage. Emmanuel G. Collins envisions the creation of an unmanned ground vehicle that could patrol large areas without putting US soldiers in harm’s way.
Hormone’s Role In Insects Could Give Insight For Cancer Treatment, Malnutrition
New research shows that in the caterpillar of the tobacco hawkmoth, tissues called imaginal discs, which give rise to structures such as the legs and eyes, form and grow despite severe starvation unless a substance called juvenile hormone is present.
Sun’s Past Strength Took Toll On Tropical Glaciers, Worsens Today’s Outlook
Variations in the strength of the sun have played a major role in glacial fluctuations in the tropical Andes for hundreds of years, and combined with current greenhouse gases generated by humans, paint an alarming picture for tropical glaciers.
Passive TV Viewing Related To Children’s Sleeping Difficulties
A recent Finnish randomized population-based study shows that TV-viewing, and particularly exposure to adult-targeted programs, such as current affairs programs, TV series and police series and movies, markedly increases the risk of sleeping difficulties in 5-6 year old children. Also passive exposure to TV increases sleeping difficulties.
Big Bang In Antarctica: Killer Crater Found Under Ice
Planetary scientists have found evidence of a meteor impact much larger and earlier than the one that killed the dinosaurs — an impact that they believe caused the biggest mass extinction in Earth’s history. The 300-mile-wide crater lies hidden more than a mile beneath the East Antarctic Ice Sheet. And the gravity measurements that reveal its existence suggest that it could date back about 250 million years — the time of the Permian-Triassic extinction, when almost all animal life on Earth died out.
New Study Calculates Millions Of Years Saved In Lives Of AIDS Patients
This year, the US federal government will spend $21 billion for HIV/AIDS research, treatment, prevention, and related activities. Is this enormous expenditure paying off? A study published in the July 1 issue of The Journal of Infectious Diseases, now available online, indicates that it is — and more so than previously thought.
Worms Hold Clue To Link Between Cancer And Ageing In Humans
Proteins which prevent cancer in humans by ensuring that cells don’t divide if they have chromosomal damage have been shown to determine lifespan in the nematode worm C. elegans. A Buck Institute study, appearing in the June 2nd issue of the journal Science, shows that checkpoint proteins, traditionally thought only to be functional in cells that divide, are also active in cells that no longer divide. The fact that the proteins appear to have dual functions opens a new way to study the connection between aging and cancer.
Landmark Study On Diabetic Foot Unveils Startling Data About Infection-induced Amputation
Study emanating from Texas A&M, Rosalind Franklin University, and University of Washington reveals strong support for the link between infections and amputations, and has promising implications for prevention strategies.
