Capturing birds using mist nets to study behaviour, movement or the demographics of a species is one of the most common research techniques in ornithology, yet until now there have been no large scale studies into the risks mist nets pose to birds. Writing in the British Ecological Society's Methods in Ecology and Evolution researchers from California used a dataset of over 345,000 records to evaluate the risks of mist netting.

Mobile phones could hold the key to people giving up smoking after a programme involving sending motivational and supportive text messages to smokers doubled quit rates at six months.
The findings of the txt2stop trial, which was led by the London School of Hygiene & Tropical Medicine and funded by the Medical Research Council, are published in The Lancet today.
PROVIDENCE, R.I. [Brown University] — Research results from the National Lung Screening Trial, published online June 29 in the New England Journal of Medicine confirm that helical low-dose CT (LDCT) scans for lung cancer reduce deaths in heavy smokers by 20 percent compared to X-ray scans, but several other key findings from the data gathered in the study, including cost-effectiveness, will be released in the next six months, said a Brown University statistician who helped lead the massive government-funded study.
June 30, 2011 – The development of agriculture was a significant event in human cultural evolution, but we are not the only organisms to have adopted an agricultural way of life. In a study published online today in Genome Research (www.genome.org), researchers have sequenced the genome of a fungus farming leaf-cutting ant, revealing new insights into the genetics and molecular biology behind this unusual lifestyle.
Scientists have found a 20 percent reduction in deaths from lung cancer among current or former heavy smokers who were screened with low-dose helical computed tomography (CT) versus those screened by chest X-ray. The primary research results from the National Lung Screening Trial (NLST) were published online today in the New England Journal of Medicine.
Philadelphia — Results of the National Lung Screening Trial (NLST) published online in the June 30 New England Journal of Medicine report a twenty percent reduction in lung cancer deaths among study participants who were screened with low-dose helical computed tomography (CT) versus those screened with chest X-ray. Conducted by the American College of Radiology Imaging Network (ACRIN) and the National Cancer Institute's Lung Screening Study Group, the NLST enrolled 53,000 current and former heavy smokers aged 55 to 74 at 33 sites across the United States.
Modern humans never co-existed with Homo erectus—a finding counter to previous hypotheses of human evolution—new excavations in Indonesia and dating analyses show. The research, reported in the journal PLoS One, offers new insights into the nature of human evolution, suggesting a different role for Homo erectus than had been previously thought.
The work was conducted by the Solo River Terrace (SoRT) Project, an international group of scientists directed by anthropologists Etty Indriati of Gadjah Mada University in Indonesia and Susan Antón of New York University.
Current or heavy smokers who were screened with low-dose spiral computed tomography (CT) scanning had a 20 percent reduction in deaths from lung cancer than did those who were screened by chest X-ray, according to results from a decade-long, large clinical trial that involved more than 53,000 people.
HOUSTON - Current and former heavy smokers can now be screened more effectively for lung cancer. Results from the National Lung Screening Trial (NLST) revealed that detecting small lung cancers with computed tomography (CT) reduces lung cancer specific mortality by 20 percent.
Reston, Va. (June 29, 2011) – A new treatment option may soon be available for children with neuroblastoma according to research published in the July issue of The Journal of Nuclear Medicine. The study tested the principle that combined positron emission tomography and X-ray computed tomography (PET/CT) may be used to select children with primary refractory or relapsed high-risk neuroblastoma for treatment with a molecular radiotherapy known as 177Lu-DOTATATE. This therapeutic option was found to be viable option for children with neuroblastomas.
"Money, money, moneyMust be funnyMoney, money, moneyAlways sunnyIn the rich man's world."-ABBA, 1976
We rely on money in our day-to-day life and it is constantly in our minds. After all, money makes the world go round, doesn't it? Now, a new study, which will be published in an upcoming issue of Psychological Science, a journal of the Association for Psychological Science, tries to better understand the psychological effect of money and how it affects our behavior, feelings and emotions.
June 29, 2011 -- The onset of puberty is a critical moment for reaching girls with health messages and information, and the stakes are particularly high in countries where the HIV/AIDS epidemic rages and where threats to female reproductive health abound. Yet to date, the healthcare community in low-resource countries has tended to neglect this opportunity and instead concentrate efforts on young women who are older and of reproductive age.
(SACRAMENTO, Calif.) — Researchers at the UC Davis Cancer Center have discovered a way of sensitizing muscle-invasive bladder cancer cells so that they succumb to the toxic effects of chemotherapy. The finding adds to mounting evidence that tiny strands of RNA — called microRNA — play key roles in some of the deadliest types of cancer.
BOSTON--Researchers at Dana-Farber Cancer Institute have demonstrated a molecular strategy they say could make a much larger variety of tumors treatable with PARP inhibitors, a promising new class of cancer drugs.
Currently, the role of PARP inhibitors has mainly been restricted to cancers whose cells lack functioning versions of the damage-repair proteins BRCA1 or BRCA2 -- chiefly certain breast and ovarian cancers.
A paper published online today in Nature reveals that glia play a key role in preventing the progression of the most prominent Rett Syndrome symptoms displayed by mouse models of the disease: lethality, irregular breathing and apneas, hypoactivity and decreased dendritic complexity. The discovery, funded in part by the Rett Syndrome Research Trust (RSRT) was led by Gail Mandel, Ph.D., an investigator of the Howard Hughes Medical Institute at Oregon Health and Science University.
