Species Detectives Track Unseen Evolution
New species are evading detection using a foolproof disguise -- their own unchanged appearance. Research suggests that the phenomenon of different animal species not being visually distinct despite other significant genetic differences is widespread in the animal kingdom. DNA profiles and distinct mating groups are the only way to spot an evolutionary splinter group from their look-alike cousins, introducing uncertainty to biodiversity estimates globally. Potential New Treatment For Insulin-dependent Diabetes
Scientists in Japan have found a way to improve on a promising diabetes treatment. In the October 3 issue of The Journal of Experimental Medicine, Masaru Taniguchi and colleagues report that transplanted insulin-producing cells survive better when the activation of a specific type of immune cell is blocked. New Model Of Cancer Syndrome Could Lead To Treatments
Scientists from MIT's Center for Cancer Research have developed a new mouse model that closely resembles Li-Fraumeni Syndrome (LFS) in humans, a syndrome that predisposes those affected to a broad range of cancers. Some 95 percent of LFS patients develop cancer by age 65. Oh, the (Lack of) Humanity
Next time a bum asks you for a quarter, look him in the eye. Give him a quarter or tell him no, but look him in the eye. We're all in this bloody mess together. Commentary by Tony Long. Yale Scientists Confirm How Crystals Form
A team of researchers at Yale University is the first to devise a way to predict the microstructure of crystals as they form in materials, according to a report in the September issue of Applied Physics Letters. Researchers in many fields including materials science, geology, physical chemistry and biochemistry will now be able to tailor material properties that are sensitive to microstructure. Researchers Observe Superradiance In A Free Electron Laser
A team of researchers at the U.S. Department of Energy's Brookhaven National Laboratory has generated extremely short light pulses using a new technique that could be used in the next generation of light sources. Published on Jan. 19, 2007, in Physical Review Letters, the research team's findings describe using a laser to control the pulse duration of light from a free electron laser as well as the first experimental observation of a phenomenon called superradiance. Drug Used In Coronary Artery Bypass Graft Surgery May Increase Risk Of
Aprotinin, a drug used for limiting blood loss in patients undergoing cardiac surgery, is associated with an increased risk of death during five years following the surgery, according to a new study in the Feb. 7 issue of JAMA. Cold Treatment Kills Fruit Fly On Citrus Fruits
Cold storage at temperatures of 2°or 3°C can effectively kill Queensland Fruit Fly in citrus stored for 14 to 16 days. This method provides an alternative to methyl bromide fumigation, which is toxic to citrus and shortens its shelf life. Methyl bromide is also being phased out in Australia because it is ozone depleting, according to researchers. Level Of Oxytocin In Pregnant Women Predicts Mother-child Bond
In animals, oxytocin, dubbed 'the hormone of love and bonding,'is critically important for the development of parenting, is elicited during sexual intercourse, and is involved in maintaining close relationships. These findings implicate oxytocin in the bonding process, but little research has been done on this relationship in humans. Now a new study demonstrates the links between oxytocin and bonding in human mothers. Inevitable Corruption of Indicators and Educators Through High-Stakes
This paper describes factors leading to corruption in K-12 standardized testing, such as cheating by teachers, administrators, and students, "teaching to the test"(often cutting out creative curriculum elements), and exclusion of low performers from the test process.
