Some caterpillers just don't want to grow up

...tadt, the project leader from Würzburg University, points out. The scientists conclude that low added mortality and intense competition among caterpillars in the nest are a prerequisite for the evolution of delayed development, but cannot explain it on their own. In contrast, sibling competition and "se...

Stem cell transplants explored at Stanford as a possible treatment for hearing loss

..."one of the leading auditory neuroscientists" and points to his stem cell regeneration research as a high priority for the institute. Heller's vision is to develop a variety of possible cures for deafness. For the past year and a half, since coming to Stanford from Harvard, he's been focused on two p...

Napoleon's mysterious death unmasked, UT Southwestern researcher says

The report, available online and in the January edition of Nature Clinical Practice Gastroenterology & Hepatology , indicates that the despot's demise was imminent. "This...

Batten down the hatches against HIV

...cing these receptors and the virus cannot find any points of attack on the surface of the cell. This could significantly slow down an HIV infection, as previous work have shown. But how to get the RNA fragments into the T-cells? The shells of nonpathogenic viruses can be used to smuggle genetic material ...

Living with water scarcity -- world must act now

...ist of the Stockholm International Water Institute points out that "reducing losses in the food chain and being careful with our diets can lead to significant water savings. Combined with other good agricultural production practices, water use could stabilize at present levels." In developed countries, pe...

Tears reveal some of their deepest secrets to researchers

...s based on electrical charges and mass. Nichols points out that researchers have used other techniques, such as chromatography, to characterize types of lipids in the tear film, but advances in mass spectrometry technology are improving research efforts. "Other scientists used different techniques to ...

Scientists produce neurons from human skin

...e beginning of synapse formation between neurons," points out Professor Berthod. In the short term, this breakthrough might have an impact in the field of neuroscience research. "Producing neurons from skin cells could solve the problem of human neural cell availability for research," explains Berthod. "...

Hay fever can send work productivity down the drain

...n a fact of life for millions of people, Szeinbach points out the importance of a proper diagnosis. The majority of study participants (405) had a traditional skin-prick test, in which a drop of allergen is placed on a patient's arm or back. The physician then pricks the skin through the drop, which lets th...

Magnetic system could be key to surgery without scars

...in humans, surgeons won’t know whether fewer entry points will result in fewer complications or faster healing, advantages usually seen in moving from conventional surgery to laparoscopic surgery. ...

Protein therapy may reduce infarct size in heart attack patients

...med tests to assess heart function at various time points and assessed safety and cardiac outcomes through six months. This trial was designed as an exploratory study to assess the potential impact of KAI-9803 in this “first-in-human?study. Results indicate that KAI-9803 may be associated with less myoc...

Fruit fly gene research may shed light on human disease processes

...ght on signal transmission in humans." Erickson points out that flies have evolved along with humans and that the two species are "close." Although he is quick to point out that the group's research has no short-term practical application, he believes down the road it has important implications for ...

How fish conquered the ocean

They show that teleost vitellogenins have undergone a post-R3 lineage-specific gene duplication to form pa...

A first glimpse of the influenza replication machine

...understand the flu polymerase and to look for weak points that could be targeted by drugs," says Darren Hart, whose team participated in the research at EMBL Grenoble. "But no one could get enough protein to analyse its structure. We developed a way to use robots to screen tens of thousands of experimental ...

...ged to make out the individual dancers." Addadi points out that, from above, isolated podosomes look like a tent with rope-like lines radiating from a central pole. "In effect," she says, "the podosomes may be more than just seals. They appear to act as highly connected nodes of communication between the...

100 percent juices found as beneficial to health as fruits and vegetables

...shed by leading health authorities. Taylor also points to a large epidemiological study, published in the September 2006 issue of the Journal of Medicine, which found that consumption of a variety of 100 percent fruit and vegetable juices was associated with a reduced risk for Alzheimer’s disease. In fa...

Researchers have been keen to characterize these glycans, but traditional analytical methods have not been sufficie...

Light wine intake is associated with longer life expectancy in men

... alcohol consumption rose and then fell at various points during the study. Users?consumption was eight grams a day in 1960, then survivors?consumption was 18 grams a day in 1985, dropping to 13 grams per day in 2000. The percentage of wine users increased during follow-up from 2 percent in 1960 to more t...
