Discovery clarifies role of peptide in biological clock

...the SCN are VIP cells, and one of the things we'll try to do next is confirm this. We will also try to understand better how VIP synchronizes pacemakers," he said. It is surprising that the process i...

Breakthrough isolating embryo-quality stem cells from blood

...perties of these primitive cells have been used to try and isolate the 5% or so with the highest stem cell potential, but no single technology has proved completely successful for human stem cells. This is where the optical stretcher could come to the rescue, picking those cells one by one according to t...

Thai spice helps cut blood sugar swings

...ere HCA has an effect in rats, the next step is to try and uncover its mechanism. He said that "if we can reduce the peaks and valleys of insulin with HCA, then it might have some application in diabetes, both in slowing progression to diabetes 2 and since these people have an obesity problem, it could p...

Cousin of Asian super termite invades Florida

...hile, as UF researchers and pest control officials try to get an accurate estimate of the new termite's range in South Florida, the Formosan termite continues to spread its destruction across Florida and much of the southeastern United States. First identified by UF/IFAS researchers in Miami-Dade and Br...

While on trail of dioxin, scientists pinpoint cancer target of green tea

...r. The team had been working on other chemicals to try to stop AH activity. "We initially hypothesized that EGCG would work in the same way as other AH antagonists, by binding directly to it. We were completely surprised that this isn't the case," says Gasiewicz, whose work was funded by the National In...

Gene silencing technique offers new strategy for treating, curing disease

...s team saw that PNAs were working, they decided to try RNA as well. "The RNA is more important because it may reflect the body's own natural mechanism for controlling gene expression, while the PNAs are synthetic," Dr. Corey said. "The experiments worked beautifully," he said. "It's hard to believe tha...

Massey Cancer Center researcher helps to identify a piece of the cancer puzzle

...f the cell signaling that occurs when cancer cells try to co-opt nearby healthy cells into helping to feed and spread growing tumors. The structure of the protein, Ang2, will be published this week in "Structure" a peer-reviewed scientific journal. "By examining structures of proteins and learning how ...

Map of life on Earth could be used on Mars

...te trait development across the tree of life. "We try to construct the core with gene sequences, and then we look at the distribution of traits such as those involved in metabolism by laying it onto the tree," she said. Timely appearances of certain traits among prokaryotes on the tree of life can betr...

Enzyme's newly discovered role may make it target for arthritis treatment

...causes AIDS, inhibits proteases, so scientists who try to block cathepsin G's role in inflammation will already have an extensive body of research results to refer to. Pham's lab uses mouse models of arthritis to study the contributions of proteases and other factors to inflammation and arthritis. One s...

Two studies document rise of superbugs in the environment

...es common sense. "If you get a cut or an abrasion, try to keep it clean and dry" and don't share towels or washcloths with others, Dr. Kaplan said. Most importantly, he added, "Wash hands, wash hands, wash hands." And if regular drug-resistant bacteria weren't bad enough, some bacteria have become multi...

Researchers develop promising new gene network analysis method

...t the Università di Bologna, tested two methods to try to model this network. One was the linear Markov model, a decades-old tool used to crunch everything from sports statistics to language production. The other was a correlation method based on network theory, which has been used to explain complex sy...

One hit of crystal meth causes birth defects

...s consistent with his mouse findings. He will also try to determine whether the methamphetamine causes other lasting damage in mice, such as impacts on learning and memory. "Methamphetamine has very different toxic effects in the fetal brain than in adult mice, which surprised me," says Wells. "In adult...

Scientists reveal how disease bacterium survives inside immune system cell

...human genes or gene pathways within this model and try to determine which of these molecules help prolong cell life following infection." Information gathered from these and similar studies, he adds, could help researchers develop therapeutics to treat or prevent bacterial infections. ...

Achilles heel of the herpes virus possibly found

...art infection. We can use the receptor molecule to try to understand the process and perhaps combat infection at this vulnerable site," says A. Oveta Fuller, Ph.D. the leader of the U-M team, senior author on the two papers and an associate professor in the U-M Medical School's Microbiology and Immunolog...

Scripps research scientists identify infertility molecule

...ursuing basic research on LPA and its receptors to try to understand their roles, particularly in the brain -- looking, for instance, at the effect of LPA on mammalian brain development. Recently, they showed that LPA can induce neurogenesis­the formation of new neurons -- in mice, and can also participa...

Tufts researchers shine light on firefly mysteries

... Lewis explained. "Although males and females both try to maximize their reproductive output and contribute to the next generation, this is not necessarily a co-operative venture and conflict often arises in nature. "For example, in Drosophila fruitflies, males' efforts to maximize their sperm's competi...

Discoveries by UAB and Florida scientists may help transplanted organs survive longer

...The next step will be to evaluate the treatment to try to protect kidney transplants in non-human primates ?and if successful there, go on to clinical trials in humans, said Agarwal. ...

Why are coyotes getting more aggressive?

...The researchers also will develop and test ways to try to induce coyotes to fear humans without harming them. "We need to determine what people are doing, for example, to encourage coyotes into their yards, such as feeding dogs or cats outdoors and leaving the dishes out or leaving animals out at night,...

Size matters: Preventing large mammal extinction

...t rather than wait for accidents to happen. We can try to work out which species are the ones we can do something for, and do some pre-emptive conservation planning. Of course, prevention is always cheaper than cure." The research means large bodied mammals such as ungulates (which include rhino and zeb...
