Elusive salamanders have role in developing new sampling models

...veloped during this project. These studies will be performed in coordination with the existing program, which includes sampling suspect ponds over the next six to 12 years. Researchers also will compare sampling effectiveness of the different methods, looking closely at cost, and also use several sites to cal...

...icularly ill or dying chickens. The investigators performed a serologic analysis of individuals exposed to infection during the outbreaks, collecting 983 blood samples from poultry farm workers in the outbreak regions. Blood was tested using three different techniques to ensure the validity of results. The o...

UW-Madison scientists zero in on drugs' sweet spots

...er precision and effect. The series of experiments performed by Thorson's team, for example, may help researchers enhance the anti-cancer effects of digitalis and downshift its influence on the heart, thus avoiding potential detrimental effects in cancer patients. "I think this (technique) is going to send us...

'Patient-choice' C-section rate rises 36%: HealthGrades study

...hows that 267,340 "patient-choice" C-sections were performed over those three years. These 17 states represent approximately 58 percent of the nation's total population. The study finds that the rate of "patient-choice" C-sections varies widely from state to state. Arizona had the smallest increase, with 1...

US/African project deciphers deadly parasite genome

... Much of the annotation of the T. parva genome was performed by two bioinformatics specialists at ILRI. "ILRI's involvement in the genome project supported the establishment of its bioinformatics unit," says Richard Bishop, the lead ILRI scientist on the genome project. The ILRI bioinformatics unit will in tu...

New research puts a fresh spin on current thinking of speech evolution in humans

...Neurosurgery, McGill University. "The researchers performed quantitative microscopic analysis of the cytoarchitecture of the region of interest and electrophysiological stimulation and recording within this region. When this area in the monkey was electrically stimulated, oral and facial motor responses were...

Bacteria in Household Dust May Trigger Asthma Symptoms

... for endotoxin. A disease association analysis was performed to correlate endotoxin concentrations to specific health outcomes. “When we analyzed the dust samples, we found that kitchen and living room floors had the highest concentrations of endotoxin,?said Darryl C. Zeldin, M.D., a Senior Investigator at NI...

PLoS Medicine publishes first trial of effect of male circumcision on HIV infection

...e, adult circumcision carries risks, especially if performed by medical personnel or traditional healers without proper training. Moreover, immediately after circumcision, men may be at a higher risk of acquiring infections (which is why the participants were asked to not to have sex for six weeks after the op...

Solexa and collaborating scientists illuminate the small RNA component of the transcriptome

...edge of the genes or sequences of interest. Solexa performed this research in its Genomic Services business unit. The Company also intends to develop this small RNA assay for use with its next-generation sequencing platform, which is scheduled to be introduced to the market by the end of this year. Using Sole...

Chernobyl: The true scale of the accident

... Strengthening those unstable structures has been performed recently, and construction of a New Safe Confinement covering the existing shelter that should serve for more than 100 years, starts in near future. The new cover will allow dismantlement of the current shelter, removal of the radioactive fuel mass f...

Regenerating worms help elucidate stem cell biology

Reddien (now an Associate Member at the Whitehead Institute for Biomedical Research), and led by Howard Hughes Medical Institute investiga...

The earliest animals had human-like genes

... clear story," says researcher Florian Raible, who performed most of the computer analyses. "The worm's genes are very similar to human genes. That's a much different picture than we've seen from the quickly-evolving species that have been studied so far." Raible is member of both Arendt's group and a second ...

Research Permits First-Ever Visualization of Psychological Stress in the Human Brain

...ical stress in a healthy human brain. Their work, performed at Penn's Center for Functional Neuroimaging, provides a neuro-imaging marker of psychological stress -- which will pave the way for the development of improved strategies for preventing or correcting the long-term health consequences of chronic stre...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality

... atmospheric mapping of nitrogen dioxide pollution performed by ERS-2's GOME and Envisat's SCIAMACHY reveals the world's largest amount of NO2 hanging above Beijing and northeast China, as reported in Nature this week. As part of ESA's Dragon Programme, European and Chinese researchers are using results retur...

Double trouble: Cells with duplicate genomes can trigger tumors

...re the paper's co-first authors. The research was performed in experimental animals, but such "double-value" cells are seen in a variety of early human cancers and in a precancerous condition called Barrett's esophagus. In addition to the extra chromosomes, the "double value" or "tetraploid" cells also duplic...
