Speeding 'fingertip' discovery -- 20 years of protein info in 1 place

...rature and the PhosphoMotif Finder tool allows any researcher to find potential phosphorylation sites in any protein of interest. “The power of this technique is not just in the numbers,?says Pandey. “Rather, we’ve found what you might call new information about old proteins, and we hope the new data will h...

Mother knows best: Plant knowledge key to childhood health in remote Amazon

... Victoria Reyes-García, PhD, coauthor and visiting researcher at Brandeis University. "However, many Tsimane' are pursuing new economic opportunities that undermine this aspect of their culture. It seems to be one of the many unintended consequences of globalization." The study evaluated the health of 330 ...

Gene hunters close in on Lou Gehrig’s disease

...tudy with lead author Jennifer Schymick and fellow researcher John Hardy, Ph.D., both of the Laboratory of Neurogenetics at the National Institute on Aging in Bethesda. Researchers from the National Institutes of Health, from the Packard Center for ALS Research at Johns Hopkins and from the University of Turin,...

New evidence of 'human' culture among primates

...mbridge researcher. Dr Antonio Moura, a Brazilian researcher from the Department of Biological Anthropology, has discovered signs that Capuchin monkeys in Brazil bang stones as a signalling device to ward off potential predators. While not conclusive, his research adds to a mounting body of evidence that s...

Scientists produce neurons from human skin

...s been achieved from human skin, according to lead researcher Professor François Berthod. This breakthrough could eventually lead to revolutionary advances in the treatment of neurodegenerative illnesses such as Parkinson’s disease. Berthod and his team described the method used to produce these neurons in a re...

MicroRNA helps prevent tumors

...ndividual microRNA, Christine Mayr, a postdoctoral researcher in the Bartel lab, picked Hmga2, a gene that is defective in a wide range of tumors. In these tumors, the protein-producing part of the Hmga2 gene is cut short and replaced with DNA from another chromosome. Biologists have mostly focused on the s...

Lizards 'shout' against a noisy background

... to 25 meters away, said Terry Ord, a postdoctoral researcher at UC Davis who is working with Judy Stamps, professor of evolution and ecology. The lizards' signals need to be strong enough for a rival to see, but not vivid enough to say "eat me" to a passing predator. But their forest home can be a visually ...

Targeting tumors the natural way

...aura Kiessling, who led the work with postdoctoral researcher Coby Carlson. "It's just not usually directed toward tumor cells." In a series of cell-based experiments, the researchers' system recognized and killed only those cells displaying high levels of receptors known as integrins. These molecules, which...

Honeydew honeys are better antioxidants than nectar honeys

...and among honeys, honeydew honey is the best,?says researcher Rosa Ana Pérez, who works at the Instituto Madrileño de Investigación y Desarrollo Rural, Agrario y Alimentario, in Madrid, Spain. Each of the 36 honeys was exposed to a range of physical and chemical tests. Honeys with high antioxidant properties...

Liposuctioned fat stem cells to repair bodies

...ttention, acknowledges Ernest Arenas, a EuroSTELLS researcher at the Karolinska Institute in Stockholm, Sweden. "Scientists in the stem cell field are starting to realise that for cell manipulations to succeed they need to pay attention to their epigenetic marks. Cells can’t be pushed along to become a differen...

'Juiced-up' battery fueled by sugar could power small portable electronics

Dutch researcher Harm Veling has demonstrated that our brains fend off distractions. If we are busy with something we suppress disrupting external influences. If we are tired, we can no longer do this. Social-psychologist Veling proved that the brain selects incomi...

Multiple malaria infection inhibits spread of parasite

...mmunity inhibits the spread of the parasite. Dutch researcher Mike van der Kolk discovered this during his research into malaria transmission under the inhabitants of Cameroon, Senegal and Indonesia. After just a few infections, people can develop immunity that inhibits transmission. Malaria is not caused by ...

'Terror bird' arrived in North America before land bridge, study finds

... igneous and metamorphic rocks, but only one other researcher worldwide has applied this technique to date the age of fossils: professor Clive Trueman from the University of Southampton in England. "It is very difficult to assess the age of fossil bones directly as they are too old to be carbon dated," Truema...

Brown team finds crucial protein role in deadly prion spread

...ar Biology, Cell Biology and Biochemistry and lead researcher on the project. The findings from Serio and her team, which appear online in PLoS Biology, build on their groundbreaking work published in Nature in 2005. That research showed that prions ?strange, self-replicating proteins that cause fatal brain ...

Cornell researcher helping develop quick, cheap HIV/AIDS test

A Cornell researcher is working to develop a quick, simple and cheap immune-system test for people in the developing world. It could help HIV/AIDS sufferers in the poorest countries get appropriate treatment to extend their lives, possibly by as much as 10 to 15 years. ...

Light-based probe 'sees' early cancers in first tests on human tissue

... on a study in hamsters, Wax and Duke postdoctoral researcher Kevin Chalut reported in the February 2007 issue of Cancer Epidemiology Biomarkers & Prevention that the technique might also be used in the identification of early lung cancer. Wax said he and his colleagues have launched a company, called On...

The influence of the menstrual cycle on the female brain

... Magnetic Resonance Imaging, Jean-Claude Dreher, a researcher at the Cognitive Neuroscience Center (CNRS/Université Lyon 1), in collaboration with an American team from the National Institute of Mental Health (Bethesda, Maryland) directed by Karen Berman, has identified, for the first time, the neural networks ...

How fish conquered the ocean

...t always been filled with fishes as nowadays" says researcher Dr. Roderick Nigel Finn at the Department of Biology, University of Bergen, Norway. "To the contrary", Dr Finn says, "the fossil record shows that the ancestors of the bony fishes (teleosts) inhabited fresh water environments for at least 150 million...
