Getting Pregnant While On The Pill: Yet Another Health Hazard Of Being
Overweight and obese women who take oral contraceptives are 60 percent to 70 percent more likely to get pregnant while on the birth-control pill, respectively, than women of lower weight, according to new findings from Fred Hutchinson Cancer Research Center that will be published in the January issue of Obstetrics &Gynecology. Hippie Society: The Youth Rebellion
Images, archival footage, and brief descriptions of events of the mid- to late 1960s, with an emphasis on the hippie movement in Canada. Also covers San Francisco's Haight Ashbury, the beatniks, and ex-hippies in the 1980s. Also includes material for teachers. From the Canadian Broadcasting Corporation (CBC). Zinc Plays Important Role In Brain Circuitry
To the multitude of substances that regulate neuronal signaling in the brain and spinal cord add a new key player: zinc. By engineering a mouse with a mutation affecting a neuronal zinc target, researchers have demonstrated a central role for zinc in modulating signaling among the neurons. Significantly, they found the mutant mouse shows the same exaggerated response to noise as children with the genetic disorder called "startle disease,"or hyperekplexia. Virus Uses Tiny RNA To Evade The Immune System
HHMI researchers have found that a virus appears to cloak itself with a recently discovered gene silencing device to evade detection and destruction by immune cells. The study may be the first to show how a virus uses the gene silencing machinery for its own infectious purposes. 3-D Holiday Gift Could Help Scientists Regulate Iron
A new study co-authored by Children's Hospital Oakland Research Institute senior scientist, Elizabeth Theil, Ph.D., is the first to show that partial copies of DNA called mRNA (or messenger RNA) morph into specific three dimensional shapes when it combines with a protein regulator called IRP1. This discovery is incredibly important to researchers who design medications based on the specific characteristics of a disease. [Odd] A Romanian couple has named their son Yahoo as a sign of gratitu
Daily Libertatea said on Thursday Cornelia and Nonu Dragoman, both from Transylvania, met and decided they were meant for each other following a three-month relationship over the net.They married and had a baby this Christmas, whom they decided to name after one of the worldwide web's most popular portals."We named him Lucian Yahoo after my father and the net, the main beacon of my life,"Cornelia Dragoman was quoted as saying. 'Sex' Helps Bacteria Cope With A Changing World
Bacteria feel pressures to evolve antibiotic resistance and other new abilities in response to a changing environment, and they react by 'stealing' genetic information from other better-adapted types of bacteria, according to research published in Nature Genetics. Professor Drives Scientific Stake Into The Heart Of Ghost, Vampire Myt
As the weather cools and Halloween approaches, chilling creaks in the stairs, bloodcurdling screams from the attic and other paranormal activity become more believable -- but not to UCF physics professor Costas Efthimiou. The laws of physics and math debunk popular myths about ghosts and vampires, according to a paper published by Efthimiou and Sohang Gandhi, a UCF graduate now studying at Cornell University. Global Changes Alter The Timing Of Plant Growth, Scientists Say
Different plant species mature at different times. Scientists studying plant communities in natural habitats call this phenomenon "complementarity."It allows species to co-exist because it reduces overlap in the time period when species compete for limited resources. Now, in a study posted online the week of Sept. 4 in Proceedings of the National Academy of Sciences, ecologists working at Stanford's Jasper Ridge Biological Preserve report evidence that climate change may alter this delicate balance. Why Organs Fail Following Massive Trauma -- Top Cause Of Death Among Y
A team of researchers is working on the problem of post-trauma immune system and organ failure, and has discovered several new biochemical pathways that play a central role, according to a study published in the Proceedings of the National Academy of Sciences. The work is changing emergency room guidelines, building the foundation for earlier diagnosis of post-trauma organ failure and making possible the design of drugs to reverse it.
