Vitamin D deficiency widespread during pregnancy

...ickets ?a disorder characterized by soft bones and thought to have been eradicated in the United States more than 50 years ago ?as well as increased risk for type 1 diabetes, asthma and schizophrenia. "A newborn's vitamin D stores are completely reliant on vitamin D from the mother," observed Dr. Bodnar, ...

Biologists call for better choice of model organisms in 'evo-devo'

...nisms are chosen on the basis of how well they are thought to represent a particular ancestral organism. In connection to this practice, the researchers point to ‘basal bias?as another way that scientists may get it wrong when choosing new model organisms. This occurs when scientists choose an organism b...

Brain works more chaotically than previously thought

...nerate new electrical impulses. "It was previously thought that neurotransmitters are only released at synapses," points out Dr. Dirk Dietrich at Bonn University. "But our findings indicate that this is not the case." The messenger attracts insulating cells Together with his colleagues Dr. Maria Kukl...

Music genes and musical geniuses

...o highlight biological kinships. In this logic, we thought it would be interesting to gather musicians and researchers in a single event, to offer meetings and debates as well as entertainment to the general audience? Each participant may submit a poster abstract by filling in the appropriate form availabl...

'The eyes have it' -- Autism research yields surprising results

...at person’s eyes. Autistic children have long been thought to be poor at interpreting people’s mental states based on facial expressions, especially expressions around the eyes. Some researchers believe that this lack of ability could be central to the social problems experienced by autistic children and ...

Unique tomatoes tops in disease-fighting antioxidants

...getables their distinctive colors. Carotenoids are thought to have a number of health benefits, such as reducing the risk of developing cancer, cardiovascular disease and macular degeneration. "The tomato is a wonderful biosynthetic factory for carotenoids, and scientists are working on ways to enhance th...

MIT device draws cells close -- but not too close -- together

Dig deeper to find Martian life

...ly discovered in the sides of craters, as they are thought to have flowed with water in the last five years. The team developed a radiation dose model to study the radiation environment for possible life on Mars. Unlike Earth, Mars is not protected by a global magnetic field or thick atmosphere and for b...

On automatic pilot

...ions aligned in parallel. Up until now it had been thought that the climbing fibre and mossy fibre systems were organised in completely different manners. However, according to Pijpers they also exhibit similarities. By injecting a viral tracer agent in various muscles, the researcher traced the cerebell...

Prion disease treatable if caught early

...aused by aberrant, infective proteins. It has been thought that the disease is untreatable. However, in previous studies with prion-infected mice, Mallucci and colleagues found that early brain degeneration can be reversed if prions are depleted in neurons. In the new studies published in Neuron, they ...

White blood cells of cancer-resistant mice overwhelm natural defenses of cancer cells

...loys to fight off bacteria, but which had not been thought to be effective in fighting off cancer. Instead, in these cancer-resistant mice, three white-blood-cell types of the innate immune system ?neutrophils, macrophages and natural killer cells ?all infiltrate the tumor site in a multi-pronged killing res...

St. Jude announces breakthrough in eye cancer treatment

...ther problems. Until now, retinoblastoma experts thought that a mechanism called the p53 pathway triggered apoptosis in other types of cancer cells, but not in retinoblastoma. However, the St. Jude team proved not only that the p53 pathway was activated in early-stage retinoblastoma, but that excessive lev...

Researchers to study why dead zone returned to Lake Erie

...Act and stimulating the environmental movement. We thought the problem was solved, and the surprise is in the last few years the dead zone is back." Researchers from U-M, the Cooperative Institute for Limnology and Ecosystems Research, NOAA, and several other universities will study the possible causes of ...

Free drug samples influence prescribing, say one in three doctors

New study aims to stop sepsis in its tracks

...o measure blood levels of certain factors that are thought to cause severe sepsis. By examining how these levels change over time and with the different interventions, the scientists will discover whether the factors can serve as molecular markers to help track organ function and recovery progress in patient...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

... known to spray defensive venom," Dossey said. "We thought if this technique really can look at small samples, well, a milking of a single walking stick is very small. It's worth a try." They discovered compounds not previously known to be present in these animals, as well as chemical differences in secreti...

Novel experiment documents evolution of genome in near-real time

...te. "We expected to find many mutated genes and we thought our results would be very difficult to understand, but neither was the case," said Christopher D. Herring, a co-author of the paper and a former member of Palsson's team who is now a research scientist at Mascoma Corp. in Lebanon, NH. All the mutan...

UCSF study will test new vaginal microbicide for herpes and HIV

...n rates. "Nonoxynol 9 was used commonly and was thought to be an extremely safe type of anti-microbial spermicide. But researchers found that it actually increased the rate of HIV infection in women. So now we realize that we must approach new microbicides a little more carefully," Moscicki said. Accor...

Stem cells engage in dialogue with the cells that regulate their futures

... replace injured tissues. She mentioned that it is thought that most, if not all, adult tissues contain stem cells. Through self-renewing division," she explained, "stem cells replenish the stem cell pool. They also produce progeny that change into other, specialized cells. Importantly, stem cells have th...
