Mutations in the BRAF gene predict sensitivity to a novel class of cancer drugs

...erapies will be more effective and less toxic than traditional chemotherapies." The study's other researchers were Christine A. Pratilas, Ayana Sawai, Andrea Basso, Qing Ye, Jose M. Lobo, and Yuhong She, all of Memorial Sloan-Kettering; Drs. Levi A.Galloway, Gad Getz, Todd R. Golub, and William R. Sellers of Da...

GROWing the next generation of water recycling plants

...of the system is that it is not 'high-tech' in the traditional sense. "It does not require sophisticated maintenance, just tending, like any garden," says Butler. The next aim for GROW is to see if it can be reduced in size to sit above a household water butt, making it serviceable for individual households. Th...

New maps reveal true extent of human footprint on Earth

...ts to grow soybean, a legume that has never been a traditional crop of Latin America. Scientists say the surge in soybean production there has a lot to do with the booming demand for soy all the way at the other end of the world - in China. Meanwhile, Monfreda notes, long-time soybean farmers in the U.S. - the w...

Ancient DNA helps UF researchers unearth potential hemophilia therapy

...lotting protein as an invader and rejects it after traditional gene therapy. But UF researchers bypassed this immune response by performing gene therapy on mice within 24 hours of their birth, when their immune systems were still naive and would accept the protein. This type of approach cannot be used in human ...

Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm

..., not previously flagged by or suspected from more traditional gene-hunting approaches, appears to influence significantly one particular risk factor - the so-called QT interval length - for sudden cardiac death. The work will be published online at Nature Genetics on April 30. "In addition to finding a geneti...

Carnegie Mellon scientists show brain uses optimal code for sound

...parameters like frequency and intensity as part of traditional sound signal processing. "Our new signal processing framework appears far more efficient, effective and concise in conveying a rich variety of natural sounds than anything else," Lewicki said. The approach by Smith and Lewicki dissects sound based...

Microbiology text tells stories, offers online resources

...compendium of facts, but rather a textbook in the traditional sense: a book that can be used for studying rather than for looking up factual information. "Not wanting to overload this book with information, we turn you to the wealth of material available on the internet," says Schaechter. Purchase of the Mic...

Mouse study reveals human X-SCID gene therapy poses substantial cancer risk

...post-transplant for less than 6 months, which is a traditional research protocol. The Salk research team, however, allowed the mice to live through their natural life span, which is about one-and-a-half years. Mice that developed lymphoma did so at an average of 10 months of age. In the human gene therapy tri...

Alcoholism, smoking and genetics among Plains American Indians

...n social settings. This may be a throwback to the traditional use of tobacco amongst American Indians." Enoch said that this study shows how there is no such thing as an "alcoholism gene" or "alcoholism allele." "Here you've got one gene, and in one population one allele of the gene is associated with a dis...

Satellites show Amazon parks, indigenous reserves stop forest clearing

... According to Nepstad, "Protecting indigenous and traditional peoples' lands and natural areas in the Amazon works to stop deforestation. The idea that many parks in the tropics only exist 'on paper' must be re-examined as must the notion that indigenous reserves are less effective than parks in protecting n...

Pleasing plant shapes explained by new computer model

...otanists can use to complement and interpret their traditional laboratory experiments. It also promises to lead to accurate models of how other organisms, including animals, develop from primordial stem cells. "This was a great example of the synergy you can have between biology and computer science and how the...

Junk DNA may not be so junky after all

... sequences in each species have changed over time, traditional methods of comparing DNA sequences between humans and zebrafish have failed to identify any potential enhancers around the RET gene because the DNA sequences differ too much. That drove the Hopkins researchers to seek and develop this new system, by...

Infused spleen cells found not to impact islet recovery and reversal of type 1 diabetes in mice

Anthrax spores may survive water treatment

Anthrax spores may survive traditional drinking water disinfection methods and can attach themselves to the inside surface of water pipes, suggesting water treatment facilities should be prepared to employ alternate disinfection methods in the unlikely event of the release of anthrax in t...

Researchers use dirt to stay one step ahead of antibiotic resistance

...ble to the drug development process, complementing traditional laboratory studies of clinical situations. By screening newly developed drugs for resistance in soil bacteria, not only can pharmaceutical companies can gain a better understanding of what may emerge in the future as clinical problems, but sufficien...

Warbling whales speak a language all their own

...hnique for animal communication research with more traditional models, such as the first order Markov model that is used to analyze bird songs, which are often shorter and simpler in structure than humpback whale songs. The Markov model proved inadequate for the whale song's complex structure. Information theo...

Growing crops to cope with climate change

...rown in the UK are suited to the soil, seasons and traditional cool, wet summers. Later flowering in barley means it has a longer growing period to amass yield. If British summers get hotter and drier we will need types of wheat, barley and other crops that flower earlier, like Mediterranean varieties, to beat s...

UCSD biologists find new evidence for one-way evolution

...ost in ancestral species. The authors suggest that traditional methods for reconstructing the history of trait evolution may be inaccurate. Discovering irreversible change for this sexual system trait highlights the importance of considering genetic data underlying the trait when reconstructing its evolutionary...
