BC catalyst discovery promises faster, cheaper drug production

...ll significantly improve the efficiency with which biologically and medicinally active molecules can be prepared," said Prof. Hoveyda, who is also chair of the department. "Such a catalyst, by shortening synthesis routes, will significantly lower cost and reduce the waste generated in laboratory syntheses." The ...

Neural networking nanotubes

...WNTs) with a view to developing these materials as biologically compatible components of medical devices, sensors, and prosthetics. SWNTs are formed from carbon atoms by various techniques including deposition and resemble a rolled up sheet of chicken wire, but on a tiny scale. They are usually just a few nanomet...

Developing uses for sugar-cane bagasse: Biotechnology applied to the paper industry

...ists from the IRD and INRA studied an alternative, biologically based, solution. Laboratory experimentation enable...d for refining pulp from bagasse that had not been biologically treated. Another benefit came in the form of a 35% improvement in the paper's mechanical characteris...

Mayo Clinic: Gene expression profiling not quite perfected in predicting lung cancer prognosis

... are often overlooked, which may be quite relevant biologically to clinical questions. The authors of the study recommend that medical scientists engaged in gene expression profiling should: Clearly define a study aim. The main focus in microarray studies should explore the molecular explanations for ...

Extraordinary life found around deep-sea gas seeps

...nearest known cold seep communities that have been biologically described are off Chile and Japan. The seeps off New Zealand are also remarkable in the sheer extent of their chemosynthetic communities,' says Dr Baco-Taylor. The team pinpointed potential seep sites using sophisticated sonar to map seafloor topo...

Fragmentation rapidly erodes Amazonian biodiversity

...tation. The Amazon contains the planet’s most biologically diverse tree communities, with up to three hundred species occurring in an area the size of just two football fields. These forests are being rapidly felled and fragmented for timber operations, cattle ranches and industrial soy farms. The team, ...

Genetic 'roadmap' charts links between drugs and human disease

...enomic signatures of more than 160 drugs and other biologically active compounds. They next developed a computer program to compare the signatures of the drugs with each other and also with the signatures seen in diseases. Using the Connectivity Map, the scientists were able to discover the mechanisms underlying ...

African wetland managers armed with new technology

...n Africa. Abundant water makes wetlands the most biologically diverse ecosystems on Earth, more productive even than tropical rainforests. Unlike rainforests, they are scattered across the world, providing regional flood and erosion prevention, water purification and nutrient recycling. For much of the 20th C...

New study finds similarities between monkey business and human business

...s easily ameliorated through market incentives ?or biologically based, arising in novel situations and in spite of experience. In a groundbreaking new study from the Journal of Political Economy, Yale researchers extend this question across species, exploring how a colony of capuchin monkeys responds to economic ...

Surprising symbiosis: Glassy-winged sharpshooter eats with friends

...nt (in this case, B. cicadellinicola), as does the biologically similar aphid. University of Arizona evolutionary biologist Nancy Moran, who has extensively studied the co-evolution of insects and their resident bacteria, recruited Eisen to the current project. "My initial interest in sharpshooter symbiosis was...

Biofuels researcher searches for new sources

...cing biofuels using "biomass," which refers to all biologically produced materials like grains, straw, hay, trees and fruits. He and his collaborators are working on a project to evaluate the ethanol production potential of various straws, hays, and silages in Montana. People can make fuel from many kinds of p...

Ecosystem services and invasive species

...thern Cumberland Plateau supports some of the most biologically diverse ecosystems in North America, but much of the land is privately owned and not under any zoning growth restrictions. Deborah McGrath and Ken Smith (Sewanee - University of the South) and their students are studying the economic and ecological...

WWF captures first-ever photo of wild rhino on Borneo

...inuous natural forests, which are some of the most biologically diverse habitats on Earth, with high numbers of unique animal and plant species. It is one of only two places in the world –Indonesia's Sumatra island is the other ?where orang-utans, elephants and rhinos still co-exist and where forests are currentl...

Exxon Valdez oil found in tidal feeding grounds of ducks, sea otters

...hat only becomes dry during the lowest tides. This biologically diverse zone is a prime feeding ground for sea otters, ducks and other wildlife. Previously, scientists believed most of the oil was deposited on beaches at higher tide levels.> The researchers randomly dug 662 pits along 32 stretches of shor...

Beekeepers work hard for the honey, despite changing tupelo forest

...the Apalachicola River floodplain, one of the most biologically diverse ecosystems in North America. Although tupelo trees can be found elsewhere, the white tupelo from which the honey featured in the 1997 movie "Ulee's Gold" is derived is found in abundance only along the Apalachicola. "It's the preferred tree...

UC Davis researchers reveal apples' protective ways

CHAVI announces international search for genes affecting HIV response

...s, within the genome. Most of these variations are biologically meaningless, but a small fraction can alter the function of a gene. Combining the effect of many slightly altered genes may significantly increase the risk of disease -- in this case, HIV/AIDS. The genome studies will be carried out at the Duke Inst...

Brazil creates buffer zone around coral reefs off Atlantic coast

...d the Abrolhos National Marine Park to protect the biologically richest coral reefs in the South Atlantic. The buffer zone, created by Brazil's Institute of Environment and Natural Resources (IBAMA), encompasses nearly 95,000 square kilometers ?an area larger than Portugal ?and protects the entire Abrolhos regio...

How can identical twins be genetically different?

...ng to understand how two people who are so similar biologically can be so different when it comes to the development of diseases like rheumatoid arthritis. U-M researchers have discovered three genes that are over-expressed in rheumatoid arthritis, or RA, that were not known to be associated with the disease be...

Mitochondrial DNA sequencing tool updated

...ations in each person's mitochondrial DNA could be biologically informative in fields as diverse as cancer diagnostics, gerontology, and criminal forensics. According to Dr. Joseph Califano, a scientist at Johns Hopkins University School of Medicine in Baltimore and senior author on the paper, the MitoChip v2.0...
