treatment because it allows us to target tumours throughout the body as opposed to just those that we can directly inject. The study is also important because it shows that we can use this approach to selectively express foreign genes in tumours, opening the door to a whole new suite of targeted cancer therapies."

The green anole lizard is an agile and active creature, and so are elements of its genome. This genomic agility and other new clues have emerged from the full sequencing of the lizard's genome and may offer insights into how the genomes of humans, mammals, and their reptilian counterparts have evolved since mammals and reptiles parted ways 320 million years ago. The researchers who completed this sequencing project reported their findings August 31 online in the journal Nature.
Scientists have discovered a genetic cause of extreme thinness for the first time, in a study published today in the journal Nature.
The research shows that people with extra copies of certain genes are much more likely to be very skinny. In one in 2000 people, part of chromosome 16 is duplicated, making men 23 times and women five times more likely to be underweight.
DENVER, Aug. 31, 2011 — The technology in "fire paint" used to protect steel beams in buildings and other structures has found a new life as a first-of-its-kind flame retardant for children's cotton sleepwear, terrycloth bathrobes and other apparel, according to a report presented here today at the 242nd National Meeting & Exposition of the American Chemical Society (ACS).
DENVER, Aug. 31, 2011 — A new birth control vaccine for white-tailed deer — a growing nuisance in urban areas for gardens and landscaping — eliminates the dangerous reproductive behavior behind the annual autumn surge in automobile-deer collisions. The vaccine, just becoming commercially available in some states, was the topic of a report here today at the 242nd National Meeting & Exposition of the American Chemical Society (ACS).
BLOOMINGTON, Ind. -- It's all about the grandkids! That's what a team led by an Indiana University biologist has learned about promiscuous female birds and why they mate outside their social pair.
Many humans find the idea of mating for life a romantic ideal, but in the natural world, non-monogamous relationships may have their benefits. According to new research published online today (Aug. 31) in Proceedings of the Royal Society B, IU postdoctoral research associate Nicole Gerlach and colleagues have uncovered one of the benefits of this promiscuity: more grandkids!
Women who breast-feed are far more likely to demonstrate a "mama bear" effect — aggressively protecting their infants and themselves — than women who bottle-feed their babies or non-mothers, according to a new study in the September issue of Psychological Science, a journal of the Association for Psychological Science.
PHILADELPHIA (August 31, 2011) – Scientists from the Monell Center report that approximately one third of patients with unexplained body malodor production test positive for the metabolic disorder trimethylaminuria (TMAU). A definitive diagnosis offers relief to these individuals, as symptoms of TMAU can hinder social and workplace interactions and cause psychological distress. But once the disease is identified, these debilitating symptoms can be ameliorated using changes in diet and other approaches.
Ophthalmologists and scientists can now better understand a rare genetic disease called Enhanced S-Cone Syndrome or Goldman-Favre Syndrome that causes increased susceptibility to blue light, night blindness, and decreased vision.
A new study shows that donations collected by check boxes on state income tax forms, fees from license plates and revenue from state lottery tickets have raised millions for breast cancer research and prevention programs across the country, according to researchers at Washington University in St. Louis.
Researchers have created and tested miniature devices that are implanted in tumors to generate oxygen, which boosts the killing power of radiation and chemotherapy and can help treat solid tumors that are hypoxic at the center, meaning the core contains low oxygen levels.
Their new implantable micro oxygen generator is an electronic device that receives ultrasound signals and uses the energy to generate a small voltage to separate oxygen and hydrogen from water ╨ a chemical operation called water electrolysis.
As a crippling drought grips much of the Southern and Southwestern United States, the population continues to grow and water resources become scarcer. One way to address the problem is by a combination of modern engineering and ancient social principles, outlined in a new paper on rainwater harvesting that will be presented at the 2011 ASME International Mechanical Engineering Congress and Exposition.
Bethesda, MD—For millions of people who live under the constant threat of Leishmania infection, a new discovery by Brazilian scientists may lead to new breakthroughs, preventing these parasites from taking hold in the body or reducing the severity of infections once they occur.
A Johns Hopkins Children's Center study of more than 3,000 hospitalized children shows that those colonized but not sick with the antibiotic-resistant bacterium MRSA are at considerable risk for developing full-blown infections.
Washington, DC, August 31, 2011 – More than 60 percent of hospital nurses' and doctors' uniforms tested positive for potentially dangerous bacteria, according to a study published in the September issue of the American Journal of Infection Control, the official publication of APIC - the Association for Professionals in Infection Control and Epidemiology.
