Parents need to be educated about HPV vaccinations for daughters

...st frequently acquired by women shortly after they start sexual activity. In a minority of women, the HPV infection persists and may result in pre-cancerous changes; these can develop into cancerous changes in these women, particularly if they are unscreened. Testing for HPV infection is becoming talked ...

Infants can organise visual information at just four months

... important to get a grip on what's going on at the start and how it develops longitudinally, so we can see how the developmental trajectory grows." According to Dr Farran, until recently Williams syndrome children were rarely diagnosed at an early enough stage. Now diagnosis is often earlier, plus there ...

New male contraceptive clears hurdle

... tests, so studies in North American men would not start for several years. Still, she notes that "We shouldn't be discouraged. We already know that RISUG works, which is half the battle in drug development. Men in studies in India have been using it for more than a decade. Now we just have to finish our h...

Cortex matures faster in youth with highest IQ

...ive" functions. The smartest 7-year-olds tended to start out with a relatively thinner cortex that thickened rapidly, peaking by age 11 or 12 before thinning. In their peers with average IQ, an initially thicker cortex peaked by age 8, with gradual thinning thereafter. Those in the high range showed an int...

K-State researchers study gene regulation in insects

"A fruit fly has a very specific shape and a beetle looks quite different. We thought it would be a good place to start, since they also develop very differently. "Once the...

Researchers reverse juvenile diabetes in animal model

...S. Food and Drug Administration (FDA) approved the start of a clinical trial to evaluate the safety and feasibility of the treatment (Phase 1 trial). The trial is expected to begin sometime this spring and will include at least 15 patients over the age of 18, with type 1 diabetes. Dr. Trucco, director of ...

Climate change: The rice genome to the rescue

... of climate change on rice production. "We need to start developing rice varieties that can tolerate higher temperatures and other aspects of climate change right now," he said. "Fortunately, the recent sequencing of the rice genome will allow us to do this much faster than we could have in the past," Dr....

Common bacteria pirate natural mechanism to get inside cells

...ne and use them to go inside, and that is how they start replicating inside the cell," he says. He and colleagues at Howard Hughes Medical Institute and Duke University Medical Center also have found that the short-lived, ubiquitous gas, nitric oxide, is a primary enabler for receptors and pathogens to m...

Marine mammals are on the frontline of failing ocean health

... of the NOAA. "Until we understand this, we can't start to say how to mitigate pollutants in the ocean." Krahn and her colleagues trace the flow of contaminants by studying the build-up of pollutants in killer whales. Different levels and timing of chemical use around the globe create distinct chemical ...

There's something fishy about human brain evolution

Natural selection at single gene demonstrated

... to infer selection at any given gene. "Once you start looking at enough cases then you realize that, oops, it's all under selection. I think a lot of that research is going to end up in the trash can," Nordborg said. The group's method can be applied to any organism, including humans. The PLoS paper ...

Diverse tropical forests defy metabolic ecology models

...r-Landau from the University of Minnesota. "So you start to think that there might be some general explanations. But the closer you look, the more differences you find '" differences that can'TMt be captured or even decently approximated by any single picture or formula." Tropical forests give modelers a...

Mayo Clinic collaboration discovers protein amplifies DNA injury signals

...ury to the repair processes, but it's an important start to understanding how we might one day design new treatments that help this repair system recover from injury or resist injury." Dysfunction of the DNA damage response pathway makes the gene unstable. Genomic instability is the driving force in tumor...

'Nano-keys' bind cell receptors and trigger allergic reactions

...t allow cells to sense their outer environment and start cellular processes within the cell. The so-called nano-keys are surfaces of silicon with a layer of polymer or a thin lipid (fatty molecules that make up cell membranes) bilayer. The surfaces, which are engineered on the micron scale (0.000001 meter...

Amazon rainforest greens up in the dry season

...is the opposite. As soon as the rains stop and you start to enter a dry period, the Amazon becomes alive. New leaves spring out, there's a flush of green growth and the greening continues as the dry season progresses." The finding holds true only for the undisturbed portion of the rainforest. Areas where ...

The American Museum of Natural History and Russian Academy of Sciences also collaborated on the new study. Lao PDR, the least densely populate...

"With this funding we can start our studies to understand how wounds in ear drums heal themselves by examining the cells and molecules in the replacement tissue," Dr Ghassemifar said. "Through DNA or gene profiling of animal models we hope to learn which molecules are active as th...
