Biodiesel study targets cleaner air, cleaner engines

...r recycled materials and oils and give farmers the chance to grow some of their own fuel. Recent government announcements supporting renewable fuels will help advance the demonstration and use of biodiesel on farms. ...

Gut research yields new anti-cancer approach

Researchers believe they have discovered by chance a new way to fight colorectal cancer, and potentially cancers of the esophagus, liver and skin. Early work shows that a group of compounds called peroxisome proliferator-activated receptor-gamma (PPARgamma) inhibitors may have an unexpected cancer-fi...

Cambodian vulture nests offer hope for species

...om conservation activities. I think we have a good chance of making it work here if we can find the support....both an additional food source for the birds and a chance to undertake coordinated counts to monitor the size and structure of the population. Chansocheat...

Metacognition: Faced with a test, rats can check their knowledge first

...r declining the test would, in principle, have the chance to weigh the likelihood that they would pass the test (and receive a large reward) against the option of declining the test and receiving a certain, but smaller, reward. In the new work, researchers utilized this approach to study the knowledge ra...

OHSU surgeon implants donated tissue allografts

...and restore joint function offers the patients the chance to return to a healthy, pain-free and productive life. Crawford said the collaboration between CTS, JRF and OHSU "has been exciting and I am delighted I could be an integral part of bringing this partnership to fruition. The result very well coul...

Study finds surfing safer than soccer

...dently, were significantly associated with a great chance of injury. "It would come as little surprise to most surfers that the injury rate more than doubles when surfing in larger surf (overhead) compared to smaller waves, as the energy of waves increases as it grows in height. In addition, a sea floor ...

Children who sleep more weigh less

...eeping an additional hour reduced young children’s chance of being overweight from 36 percent to 30 percent, while it reduced older children's risk from 34 percent to 30 percent. Although the National Sleep Foundation recommends that children ages 5 to 12 get 10 to 11 hours of sleep each night and adoles...

A genetic 'gang of 4' drives spread of breast cancer

...sed, "there are already treatments to diminish the chance of metastasis in breast cancer, so such trials would have to be designed very carefully to understand how and whether the new drug combination would be of additional benefit." In the article published in the Proceedings of the National Academy of Sci...

Protein fragments sequenced in 68 million-year-old Tyrannosaurus rex

... spectrometry methods. "This allows you to get the chance to say, ‘Wait, they really are related because their sequences are related.?We didn’t get enough sequences to definitively say that, but what sequences we got support that idea." In another study appearing in the same issue of Science, Mary Schwei...

Liver regeneration may be simpler than previously thought

...maining portion of their liver could be their only chance of survival. To investigate how the liver regenerates, Karp and his colleagues set out to determine which proteins are involved in the regenerating cells. The scientists were also interested in testing whether regenerating cells behave like embryo...

Research on grey mould offers possible breakthrough in tomato cultivation

...r atmospheric humidity that actually increases the chance of grey mould activity. By providing tomato varieties resistant to grey mould, De Ruiter Seeds will fill a worldwide need that has long been around. The research was partly financed by STW (the Technology and Sciences Association) and De Ruiter Se...

New study sheds light on 'dark states' in DNA

...A molecule can dissipate UV energy, the lesser the chance that it will sustain damage -- so goes the conventional scientific wisdom. So the dark states, which are much longer lived than previously known states created by UV light, may be linked to DNA damage. The existence of this dark energy state -- dub...

Autism gene identified by researchers at Yale working with a global research consortium

...a child has more of these genes, there is a higher chance of being born with autism or a more severe form of the disease. Autism is a complex brain disorder that inhibits a person’s ability to communicate and develop social relationships, and is often accompanied by extreme behavioral challenges. Autism...

Vasectomy may put men at risk for type of dementia

In addition, the men who had undergone a vasectomy developed PPA at a younger age (58 years) than men with PPA who hadn't had one (62 years.) While PPA robs people of their ability to speak and understand language, an unusual...

Wheat can fatally starve insect predators

...the weak, avirulent larvae on the same leaf have a chance to survive. The researchers discovered that Hessian fly larvae reprogramming of resistant plant cells only occurs at sites where the insects attack. The study also revealed that increased numbers of larvae on a plant caused a parallel increas...

Protein sensor for fatty acid buildup in mitochondria

... turn, provides the cell energy while reducing the chance that excess fatty acids will accumulate. The St. Jude discovery explains how the fatty acid-sensing enzyme PanK2 tailors production of this key molecule, coenzyme A (CoA), to the cell's energy demands. Understanding PanK2 function is also important...

Selective marker found to indicate aggressive form of breast cancer

...nd, in doing so, detect the cancer before it has a chance to come back." Basal epithelial tumors lack important molecular targets such as the estrogen receptor, progesterone receptor and Her2. This not only makes positive diagnosis difficult, say researchers, but also eliminates several important lines ...

Racing neurons control whether we stop or go

...teracts with ‘go?very briefly—it basically has one chance to knock ‘go?out of the race. It needs to react strongly and rapidly after the stop signal is given," Schall said. "If it is successful, the subject stops his or her planned movement. If it is unsuccessful, the subject goes ahead. In individuals with...

Antivirals effectively curb influenza virus

...er product reduced by 75 percent to 81 percent the chance that an exposed person would become ill with influenza. The researchers' analysis found a significant reduction in infectiousness, as defined by reductions in influenza illnesses in household contacts, when oseltamivir was used for treatment of ill...

Small molecule dervived from Rb2/p130 could act as cancer therapeutic

...o most gene therapies; therefore Spa310 has a good chance to succeed as an anti-cancer therapy. For these reasons, he believes it may be easier to get approval for clinical trials. "Fifteen years after discovering Rb2/p130, our research and hard work has led us to the discovery of this small molecule, w...
