BBC Science &Nature: Genes
Collection of content from the British Broadcasting Corporation (BBC) on topics related to the field of genetics. Covers basic information about human genetics, genetic modification of animals, cloning, "designer babies,"genetically modified (GM) food, and DNA as evidence in solving crimes. Includes interactive features and games. First Baby Is Born After Oocytes Were Matured In The Lab And Frozen
The first baby to be created from an egg that had been matured in the laboratory, frozen, thawed and then fertilized, has been born in Canada. Three other women are pregnant by the same process. The research was presented to the 23rd annual meeting of the European Society of Human Reproduction and Embryology on Monday, July 2. How Pain Distracts The Brain
Anybody who's tried to concentrate on work while suffering a headache knows that pain compellingly commands attention -- which is how evolution helped ensure survival in a painful world. Now, researchers have pinpointed the brain region responsible for pain's ability to affect cognitive processing. They have found that this pain-related brain region is distinct from the one involved in cognitive processing interference due to a distracting memory task. Cuter Scooter Defined By Electricity, Portability
It's energy efficient, it's clean, compact and simple, and, above all, it's very cool. Motor scooters are a very popular form of transportation in Asian and European cities, Mitchell said, because they provide convenient, inexpensive transportation. But conventional scooters, using inefficient two-stroke gas engines, are also a source of local air pollution. The new design "was all about providing a clean, green, silent electric scooter that would provide, even better, the same kind of urban mobility,"he said. High-maintenance Dynamics At Work May Affect Subsequent Performance
New research from Northwestern University shows that high-maintenance or difficult interactions indeed drain us. Most importantly, the study demonstrates how those draining social dynamics, in which an individual is trying so hard to regulate his or her behavior, can impair success on subsequent unrelated tasks. Chemical Warfare Ravages Mental Health Of Iranian Civilians
Iranian civilians exposed to high-intensity warfare and chemical weapons are experiencing significantly higher levels of psychological distress compared to those exposed to low-intensity warfare but not chemical weapons, researchers at Yale School of Medicine report in the August 2 issue of the Journal of the American Medical Association devoted to the theme of violence and human rights. Scientists Uncover New Target In Cancer Mutation Puzzle
University of Rochester scientists, while investigating the two most frequent types of mutations in cancer, discovered a possible new route to treatment that would take advantage of the mutations instead of trying to repair them. The research is reported online this week in the journal Nature Structural &Molecular Biology. New Gas Sensors Patterned With Conducting Polymer
An improved method for depositing nanoporous, conducting polymer films on miniaturized device features has been demonstrated by researchers at the National Institute of Standards and Technology (NIST). Described in the April 6 issue of the Journal of the American Chemical Society,* the method may be useful as a general technique for reproducibly fabricating microdevices such as sensors for detecting toxic chemicals. NOAA Reports Wet, Warm Year For The U.S. In 2004
With the end of 2004, it will rank among the top 10 wettest years on record for the contiguous United States and is expected to be warmer than average, according to scientists at the NOAA Climatic Data Center in Asheville, N.C. Can Hemp Help The Everglades?
Within Southern Florida, soil and water conditions indicate potential for leaching from the use of atrazine-based herbicides in corn crops. Scientists conducted studies to evaluate the specific groundwater risk from atrazine use by focusing on sunn hemp which seems to have the potential to greatly reduce that risk.
