Cannabis: Potent Anti-depressant In Low Doses, Worsens Depression At H
A new neurobiological study has found that a synthetic form of THC, the active ingredient in cannabis, is an effective anti-depressant at low doses. However, at higher doses, the effect reverses itself and can actually worsen depression and other psychiatric conditions like psychosis. Book Editors: Debut Novels, Book Publishers: First Novels
List of hundreds of U.S. book publishers who "have, at least once, bought the rights to first novels by unknown novelists or nonfiction writers."Also includes links to book publisher lists in the areas of business, children's books, cookbooks, health, reference, humor, religion, and sports. From an author of a book about ways to market books. Note: Includes commercial content for the author's book. New Factor Affects Fertility
A protein called TAF4b that helps regulate gene expression in the testis apparently affects the ability of those organs to produce and maintain levels of sperm needed for fertility in mice, according to research done by investigators at Baylor College of Medicine (BCM) in Houston. Better Bubbling Slurry
Dutch-sponsored researcher Keshav Ruthiya has made considerable improvements to a so-called slurry bubble column. The chemical industry uses these bubble columns for reactions between gases and liquids, for example, for organic wastewater purification or the synthesis of hydrocarbons. Various companies are interested in using Ruthiya's results in commercial reactors. [Ironic] Professional beggars prowling about the streets of Moroccan c
The government plans to crack down on the scam used by faux beggars in growing numbers for a kind of "emotional blackmail", a cabinet minister was quoted as saying... Who Should 'Own'Genetic Information?
We all share our genetic make up with relatives, but should we also share ownership of the results of DNA analysis or should this knowledge be considered private? A clinical geneticist believes that if anyone is to own genetic information, it has to be all those who have inherited it and, more importantly, it must be available to all those who might be at risk. The question, she says, is how to balance a right to privacy with disclosing risks to others. Preposterous Headdresses and Feathered Ladies: Hair, Wigs, Barbers, an
This companion to a 2003 exhibit at the Yale University's Lewis Walpole Library features "a selection of prints [from the second half of the 18th century] focused on hair and wigs, and on the hairdressers and barbers who created and tended them."Includes images of prints such as "A Doleful Disaster, or Miss Fubby Fatarmin's Wig Caught Fire"and "A French Hair Dresser Running through the Streets to his Customers." Light-sensitive Photoswitches Could Restore Sight To Those With Macula
The major cause of blindness in this country is the death of photoreceptors -- rods and cones -- in the retina, a disease called macular degeneration. A possible new therapy involves inserting photoswitches into surviving retinal cells, giving them the gift of sight. NIH's nanomedicine initiative just awarded UC Berkeley and Lawrence Berkekley National Laboratory scientists $6 million to pursue this technique in mice. Z Machine Melts Diamond To Puddle In Experiments On Capsule For Nuclea
Sandia's Z machine, by creating pressures more than 10 million times that of the atmosphere at sea level, has turned a diamond sheet into a pool of liquid, in an experiment to better understand the characteristics of diamond under the extreme pressure it would face when used as a capsule for a BB-sized pellet intended to fuel a nuclear fusion reaction. Measuring Carbon Nanotube Interactions At Atomic Level
Carbon nanotubes have been employed for a variety of uses including composite materials, biosensors, nano-electronic circuits and membranes. While they have proven useful for these purposes, no one really knows much about what?s going on at the molecular level. For example, how do nanotubes and chemical functional groups interact with each other on the atomic scale? Answering this question could lead to improvements in future nano devices.
