Seeing Previously Invisible Molecules For The First Time Posted: 24 Oct 2009 02:00 PM PDT Chemists have developed a new microscopic technique for seeing, in color, molecules with undetectable fluorescence. The room-temperature technique allows researchers to identify previously unseen molecules in living organisms and offers broad applications in biomedical imaging and research. |
Treatment For Epilepsy Is Possible Culprit For Development Of Schizophrenia Posted: 24 Oct 2009 02:00 PM PDT Researchers say antiepilectic drug treatments administered when the brain is developing appear to trigger schizophrenia-like behavior in animal models. In humans, having a history of seizures in infancy is a significant risk factor for development of schizophrenia later in life, but it is not known whether the elevated risk is due to seizures themselves, or from side effects antiepileptic drug treatment. |

Female Choice Benefits Mothers More Than Offspring Posted: 24 Oct 2009 08:00 AM PDT The great diversity of male sexual traits, ranging from peacock's elaborate train to formidable genitalia of male seed beetles, is the result of female choice. But why do females choose among males? Researchers found no support for the theory that the female choice is connected to "good genes." |
General Anesthetics Lead To Learning Disabilities In Animal Models Posted: 24 Oct 2009 08:00 AM PDT Blocking the NMDA receptor in immature rats leads to profound, rapid brain injury and disruption of auditory function as the animals mature. |

The research offers a new and highly promising candidate for enzyme replacement therapy for Fabry disease. |
New Artificial Enzyme Safer For Nature Posted: 24 Oct 2009 02:00 AM PDT Polluting industrial processes can be made safer with enzymes. But only a short range of enzymes have been available for the chemical industry. Researchers in Denmark have recently succeeded in producing an artificial enzyme that points the way to enzymes tailor-made for any application. |
Well-educated Women Hardest Hit By Breast Cancer Posted: 24 Oct 2009 02:00 AM PDT Well-educated women and those who live alone are emotionally the hardest hit by breast cancer, according to new findings. The study found that older women tended to experience lower levels of overall well-being compared to women of similar age in the community two years after their diagnosis. |
Long Night Falls Over Saturn's Rings Posted: 23 Oct 2009 05:00 PM PDT As Saturn's rings orbit the planet, a section is typically in the planet's shadow, experiencing a brief night lasting from 6 to 14 hours. However, once approximately every 15 years, night falls over the entire visible ring system for about four days. |
Pesticides Exposure Linked To Suicidal Thoughts Posted: 23 Oct 2009 05:00 PM PDT People with higher levels of pesticide exposure are more likely to have suicidal thoughts according to new research. The agricultural pesticides commonly used in China are organophosphates which are in wide use in many lower income countries but have been banned in many Western nations. |
The Lotus's Clever Way Of Staying Dry Posted: 23 Oct 2009 05:00 PM PDT Scientists finally understand how the lotus plant keeps itself clean and dry. It took an ultra high speed camera, a powerful microscope and an audio speaker to unlock a secret that has puzzled scientists for ages. |
Amino Acid May Help Reduce Cocaine Cravings Posted: 23 Oct 2009 05:00 PM PDT A new study in rats has found that N-acetylcysteine (NAC), a commonly available and generally nontoxic amino acid derivative, reverses changes in the brain's circuitry associated with cocaine addiction. The reversal appears to lessen the cravings associated with cocaine, thus providing protection against relapse. |
Iberian Wolves Prefer Wild Roe Deer To Domestic Animals Posted: 23 Oct 2009 05:00 PM PDT A Spanish researcher has analyzed the preferences of wolves from the north east of the Iberian Peninsula to demonstrate that, in reality, their favorite prey are roe deer, deer and wild boar, ahead of domestic ruminants (sheep, goats, cows and horses). |
IVF Insurance Coverage Yields Fewer Multiple Births, Researchers Find Posted: 23 Oct 2009 05:00 PM PDT The proportion of in vitro fertilization multiple births was lower in the eight states that provide insurance coverage for couples seeking IVF treatment, primarily due to fewer embryos transferred per cycle, researchers report. |

Boys With Urogenital Birth Defects Are 33 Percent More Common In Villages Sprayed With DDT Posted: 23 Oct 2009 11:00 AM PDT Women who lived in villages sprayed with DDT to reduce malaria gave birth to 33 percent more baby boys with urogenital birth defects between 2004 and 2006 than women in unsprayed villages, according to a new study. DDT can stay in the body for up to 20 years and the babies in the study were born five to nine years after official records showed their mothers were exposed to DDT spraying. |
Genome Of Microbe Silently Shaping Ecology Of Ocean Dead Zones Described Posted: 23 Oct 2009 11:00 AM PDT The expansion of oxygen minimum zones (OMZs) affects the processes by which carbon is captured and sequestered on the seafloor. Researchers describe the metagenome of an abundant but uncultivated microbe from a fjord on the coast of British Columbia, Canada that is silently helping to shape the ecology of OMZs worldwide. |
