Carbon dioxide has been getting a bad rap for the last few years, what with "Waterworld" and the IPCC's preference for French nuclear plants, but laser resurfacing appears to be an effective long-term treatment for facial wrinkles, according to a report in the July/August issue of Archives of Facial Plastic Surgery. So at least aging rich women will look good when the planet dies.

The carbon dioxide laser vaporizes water molecules inside and outside of cells, causing thermal damage to the surrounding tissue, the authors write as background information in the article. In response to this insult, the skin produces more of the protein collagen, which fills in wrinkles. "In addition to structural changes, the healing process frequently leads to pigmentary [coloring] changes," the authors write. "These changes in skin pigmentation may be desirable, such as when patients wish to remove solar evidence of aging; however, changes in pigmentation after treatment can often be a troubling adverse effect."

- Expansion of Reseller Channel Key Component of Company's Strategy

Avistar Communications Corporation (Nasdaq: AVSR), a leading provider of unified visual communications solutions, has signed a strategic partnership agreement with City Information Services Limited (CityIS Ltd.), a global visual communications company. The agreement offers CityIS' clients a cost-effective, user-friendly and proven desktop videoconferencing solution that is built to easily interoperate with room solutions and extend video to the desktop, office, home or on the road.

After completing one of the longest running experiments ever done on a lake, researchers from the University of Alberta, University of Minnesota and the Freshwater Institute, contend that nitrogen control, in which the European Union and many other jurisdictions around the world are investing millions of dollars, is not effective and in fact, may actually increase the problem of cultural eutrophication.

The dramatic rise in cultural eutrophication—the addition of nutrients to a body of water due to human activity that often causes huge algal blooms, fish kills and other problems in lakes throughout the world—has resulted from increased deposits of nutrients to lakes, largely from human sewage and agricultural wastes.

If you really love the outdoors, you should never experience it, according to a new study by conservation biologists from the University of California, Berkeley.

The study compared parks in the San Francisco Bay Area that allow only quiet recreation such as hiking or dog walking with nearby nature reserves that allow no public access. Evidence of some native carnivore populations - coyote and bobcat - was more than five times lower in parks that allow public access than in neighboring reserves where humans don't tread, the researchers report.

The dearth of these animals in the parks carries implications beyond just these species. Since the carnivores in the study are often the top predators in their areas, these animals also shape the rest of their surrounding ecosystems. The flight of large animals from heavily visited parks for more serene surroundings could, in turn, influence populations of small animals and plants, the researchers said.

Elvira Fortunato and colleagues from the Centro de Investigação de Materiais (Cenimat/I3N), at Faculdade de Ciências e Tecnologia, Universidade Nova de Lisboa, made the first Field Effect Transistor (FET) with a paper «interstrate» layer.

There is an increased interest in the use of biopolymers for low-cost electronic applications. Since cellulose is the Earth’s major biopolymer, some international teams have reported using paper as the physical support (substrate) of electronic devices but no one had used paper as an interstrate component of a FET.

The electrical performance of the new device rivals oxide-based thin film transistors (TFTs) produced on glass or crystalline silicon substrates. Full results will be published in September's in IEEE Electron Device Letters.

- July 25th Marks 40th Anniversary of Vatican's Devastating Decision

Forty years ago, a decision was announced that has had a catastrophic impact on the poor and powerless around the world. On July 25, 1968, Pope Paul VI slammed the door on the hopes of the vast majority of Catholics and confirmed a complete prohibition on modern methods of contraception. The papal encyclical Humanae Vitae was a defining moment in modern church history and continues to be a source of great conflict and division in the church.

Oxytocin is a neuropeptide that is secreted by the body during massage, childbirth and breastfeeding to induce a calming, analgesic effect. Animal studies have also shown that oxytocin promotes social interaction, such as during the courting process. The hormone has a direct influence on the amygdala, a brain area that is important for social interaction and for identifying immediate emotional threats.

Swedish and British scientists have shown using functional magnetic resonance imaging (fMRI) that the hormone oxytocin can inhibit feelings of anxiety in specific individuals. Their discovery might lead to a better understanding and the improved treatment of psychiatric affections in which people feel distressed when meeting others, such as in cases of autism and social phobia.

Taking the epilepsy drug topiramate alone or along with other epilepsy drugs during pregnancy may increase the risk of birth defects, according to a study published in the July 22, 2008, issue of Neurology.

Research has shown that many epilepsy drugs increase the risk of birth defects, but little research has been done on topiramate. Studies have shown that topiramate increases the risk of birth defects in animals. Maintaining effective epilepsy treatment during pregnancy is crucial because seizures may cause harm to the fetus.

Even if you're a caricature of the worst kind of maintenance person, such as Groundskeeper Willie in "The Simpson", there's a lesson for real life teachers.

Apparently, the lesson is 'don't be like that.' And the rest of the Simpsons supporting cast can teach educators a thing or two as well, say two academics in their paper, “Images of the Teacher in The Simpsons: Subversive, Superficial, or Sentimental?” which was presented at “The Teacher: Image, Icon, Identity” conference in Glasgow, Scotland.

“Given the often central role that the figure of the teacher plays in ‘The Simpsons,’ there is a…rich vein that could be mined for the purposes of teacher education, whether through initial training or continuing professional development,” says Gavin Morrison, curator of the University Galleries at Texas Christian University in Fort Worth and co-author Alan Britton of the University of Glasgow.
