Watching The Birth And Death Of Exotic Molecules
Researchers from Korea, Italy, France and the ESRF have just observed how a molecule changes structure after being hit with a short flash of laser light. Thanks to very intense pulses of X-rays from the synchrotron and novel data analysis, they were able to confirm a long standing hypothesis regarding the evolution of this molecule. The results are published in Science Express of 14 July. [Funny] A referee has sent himself off in an English amateur league ma
Andy Wain had to abandon the Sunday league match between Peterborough North End and a Royal Mail side in the 63rd minute after throwing down his whistle and marching up to confront North End's keeper. Arsenic Triggers Unique Mechanism In Rare Leukemia, Researchers Find
Dartmouth Medical School researchers have identified a new way that arsenite, a form of arsenic, acts in treating a rare cancer known as APL, or acute promyelocytic leukemia. Their study is published in the Jan. 3 issue of the Journal of the National Cancer Institute. Enduring Voices: Saving Disappearing Languages
"Every 14 days a language dies. By 2100, more than half of the more than 7,000 languages spoken on Earth ... will likely disappear."This goal of this project "is to document endangered languages and prevent language extinction."Features background about selected endangered-language hot spots around the world (with some sound clips), a discussion of global trends, descriptions of expeditions, and a glossary. From National Geographic and the Living Tongues Institute for Endangered Languages. Youth With HIV Take More Risks After New Meds Introduced
Teens with HIV are having more risky sex with more partners than their counterparts did in the years before powerful new medications for HIV were introduced in 1996, according to a new report in the American Journal of Health Behavior. Molecular Motors Cooperate In Moving Cellular Cargo, Study Shows
Researchers using an extremely fast and accurate imaging technique have shed light on the tiny movements of molecular motors that shuttle material within living cells. The motors cooperate in a delicate choreography of steps, rather than engaging in the brute-force tug of war many scientists had imagined. Non-invasive, Real-time Monitoring For Sepsis In Neonates Goes Nationa
Imagine being able to know ahead of time when a baby will get a serious infection and then being able to treat the infection before it can affect his or her tender life. More than a dream, researchers at the University of Virginia Health System have developed a way to monitor babies in neonatal intensive care units and predict sepsis before there is any indication of illness. HIV Domains Take On New Functions In Mediating Immunity
HIV evades the host immune system to cause infection. In a JCI study researchers examine the fusion peptide (FP) of HIV and show it plays two roles in HIV infection -- it mediates fusion of the virus with the cell membrane, while also downregulating the T cell responses that normally block infection. The authors show that FP ameliorates the autoimmune disease adjuvant arthritis in rats. This study shows that FP, independent of HIV, may provide a novel way to decrease undesirable immune responses. John Lennon
Compilation of materials about singer/songwriter John Lennon, who was a member of the British rock group the Beatles and who was killed in December 1980 in New York. Includes a biography, articles, album reviews, photos, and a discography. From Rolling Stone magazine. Desertification Alters Regional Ecosystem Climate Interactions
Using advanced remote-sensing techniques from a U-2 surveillance plane and field studies, scientists from the Carnegie Institution Department of Global Ecology have for the first time determined large-scale interactions between ecosystems and the climate during the process of desertification.
