New mechanism for nutrient uptake discovered

...of transporting nutrients individually, so we were really surprised to find that the pores simply can't act without stimulation from their neighbors." In earlier research the Carnegie scientists, with colleagues, identified the genes responsible for initiating nitrogen uptake in plants. That identificati...

Trusting your instincts leads you to the right answer

...gnition engages and examines whether the candidate really is the target or not. If the target is not distinctive enough in the 'eyes' of the conscious, failure of identification can occur." ...

MU researcher placing eye implants in cats to help humans see

...trical impulses in parts of the retina. "We are really excited about the potential uses for this technology and the potential to create improved vision in some of the millions of people affected worldwide with retinal blindness," Narfstrom said. "This technology also may be beneficial for pets that have ...

Iowa State University botanists identify new species of North American bamboo

...ld, and questions remained as to whether there was really more than just a single species. In 2003, with funding from the National Geographic Society, Clark and Triplett set off for the Southeast to find the switch cane and river cane in their native habitats. "Once we actually saw the plants in the fie...

Wheat can fatally starve insect predators

... active and the timing of the interactions, we can really understand what the insect says to the plant and how the plant responds," Williams said. The Hessian fly, which German mercenaries apparently introduced into North America during the Revolutionary War, causes catastrophic losses if not controlled ...

New study may show how to forestall a fatal, virus-caused immune-system meltdown

...n a disease like Lassa fever. “Early on, you can’t really differentiate these nasty hemorrhagic fever viruse...s, and one that may be very helpful, since there’s really no incentive for drug companies to go out and develop new antiviral compounds for viruses that may o...

FSU researchers determine a critical factor in workings of proteins

... between proteins, proposed by Zhou and coworkers, really works."...

Racing neurons control whether we stop or go

...hat has very different histories and approaches is really starting to come together." "You develop a model to explain behavior and in many ways it’s just made up," Logan said. "But then you find out that it says something about what the neurons are doing, and that’s exciting." ...

Researchers find hepatitis A and hepatitis C attack same protein to block immune defenses

...s. "With 30,000-plus proteins in the cell, it’s really remarkable that these two very different viruses have chosen to strike at the same one," said Dr. Stanley Lemon, director of UTMB’s Institute for Human Infections and Immunity and National Institutes of Health-funded Hepatitis C Research Center. Lemo...

Dual gene therapy suppresses lung cancer in preclinical test

... or normal cells when they are overexpressed. It's really just cancer cells where they seem to have their effect. Ultimately, the usefulness of this approach has to be proven in clinical trials." ...

Growth hormone is not the anti-aging bullet for healthy adults

... the scientific evidence, we found that there were really only about 500 patients involved in rigorous controlled trials. And only a few more than 200 actually received growth hormone. "Think about all the scientific claims made on anti-aging Web sites based on this small population of patients. The FDA ...

Amur leopard still on the brink of extinction, scientists say

...r is not the big question." Fomenko said, "What is really important is that the predator is on the brink of extinction. And still a unified protected area with national park status has not been established, which is the most important thing for the leopards' survival." At least four leopard litters were ...

Nanotechnology shows promise as next wrinkle fighter

...rinkle before it starts. "Everything starts at a really small scale, so if we can prevent the buckling at the very beginning ?at the nano level ?we can eliminate large scale wrinkles," Ilsoon said. "Wrinkles can initiate from the small scale, and when it grows we cannot remove it." Nanoparticles already...

Scientists unlock secret of what makes plants flower

...o carried out the research, said: "This could be a really important breakthrough in plant science. Since the 1930s when it first became clear that something was communicating the perception of changes in day length in leaves to the shoot apex, and causing flowering, scientists have been trying to work out e...

Study uncovers a lethal secret of 1918 influenza virus

... does something to the host that allows it to grow really well," says Kawaoka. "But we don't know what that is." Knowing that the virus does something early in infection to trigger such a devastating immune response may provide biomedical researchers with clues about how to intervene and stop or mitigate...

Scientists perform 'tricky' operation

...ataset the search for alternative drug targets can really take-off." Amazingly, the pesky parasite was found to have an exceptionally large collection of DNA, with the possibility of having more genes than humans. But Ms Dunne said while the sequencing of the genome project has largely elevated aware...

Studies yield insight into the numerical brain

...biguously establish that the subjects' brains were really reacting to numerical quantity, the researcher occasionally injected a "deviant stimulus" into the second presentation of a quantity as the brain was adapting to it. This deviant stimulus consisted of a different number that was either close to, or f...

No sex for 40 million years? No problem

... sexual organisms. Dr Barraclough adds: "These really are amazing creatures, whose very existence calls into question scientific understanding, because it is generally thought that asexual creatures die out quickly, but these have been around for millions of years. "Our proof that natural selection ...

RNAi shows promise in gene therapy, Stanford researcher says

...years and this is the first thing we've done that really looks promising," said Kay, professor of genetics and of pediatrics at the Stanford University School of Medicine. Kay will talk about future uses for RNAi gene therapy at the American Association for the Advancement of Sciences annual meeting i...

New test for most virulent HPV strains under study

...e something wrong,?he says, noting that Pap smears really don’t add much to the equation. Still, when he lectures around the country and asks for a show of hands of physicians using HPV tests in women over 30, few go up; he hopes that will change. “I think it’s a possibility in the future that we won’...
