...roblem solving. The Patent Lens will also develop analyses and foster the capacity in the developing world to create patent maps of the key emerging technologies that could be constrained by complex intellectual property rights worldwide, including the rice genome itself. These patent 'landscapes' will be us...

Technique offers new view of dynamic biological landscape

...s," said Weissman. "But we wanted to approach such analyses in a systematic way and to use the new generation of high-throughput technology to quantitatively explore large numbers of epistatic genetic interactions at once." The E-MAP technique consists of selectively "dialing down" the activity of a multitu...

Mapping alcohol brain damage

...ve averaged more than 10 drinks a day. The group analyses samples using a microarray analysis, a process they pioneered with human brain samples in 2000. From a DNA sample applied to a microscope slide, the microarray computer produces about 50,000 coloured spots showing which genes are expressed or switc...

Hepatitis B accounts for 40 percent of 'missing' Asian women

...e child. This evidence includes both cross-country analyses and natural experimentation based on recent vaccination campaigns. In addition, hepatitis B is common in many Asian countries, particularly China, where some 10 to 15 percent of the population is infected. Using data on viral prevalence by country ...

Phenotype is influenced by nature, nurture and noise

...Gillespie algorithm and sophisticated mathematical analyses of sets of biochemical reactions, the team discovered how the combination of intrinsic noise and biochemical delays also generates oscillations in phenotype. "We think an analysis of such fine details of gene regulation explains not only the observe...

Key brain regulatory gene shows evolution in humans

...Ethiopia, India, Italy and Papua New Guinea. Those analyses showed higher differences among the individual populations, but reduced variation within them. Such a pattern is a signature of evolutionary selection acting on the genetic sequence, said Wray. Still mysterious, he said, is how the prodynorphin gene...

Genetic analysis of cavefish reveals more about evolution

...s caused by mutations in the same gene. Subsequent analyses revealed that Oca2 is the gene responsible for pigmentation in the cavefish and that the deletion of a specific exon, or protein- coding DNA sequence, produced albinism. What remains a mystery is why the same gene should be mutated independently i...

Mining biotech's data mother lode

...'s how it works. One element of the software suite analyses over-expressing genes discovered during micro assays to establish what proteins become encoded. This uses standard techniques.A second analysis tool in the suite predicts what possible protein-protein interactions are taking place. This is novel. Whe...

Multiple genes permit closely related fish species to mix and match their color vision

...hers performed physiological and molecular genetic analyses of color vision in cichlid fish from Lake Malawi and demonstrated that differences in color vision between closely related species arise from individual species' using different subsets of distinct visual pigments. The scientists showed that although...

Scientists pinpoint inflammation gene

...iations among individuals. These molecular genetic analyses were performed at the International Diabetes Institute in Melbourne, Australia, and directed by Curran and Dr Jeremy Jowett. Back in San Antonio, researchers used novel statistical methods developed by Blangero and other SFBR scientists to sift thro...

Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

...inable livelihoods than fishing. According to new analyses by the Malaysia-based WorldFish Centre (see ? Rebuilding Boats May Not Equal Rebuilding Livelihoods and ? Rehabilitating Livelihoods in Tsunami-Affected Coastal Communities in Asia, at http://www.worldfishcenter.org/tsunami/default.asp ), those hard...

Seaweed yields new compounds with pharmaceutical potential

... magnetic resonance spectroscopy and mass spectral analyses to determine how carbon, oxygen, bromine and hydrogen atoms connected to make up the molecular structures of the 10 new natural products. Much research is left to do before any of these compounds are used to formulate a drug available on the market...

Russian 'surrogate' alcohols are a killer

...and other spirits such as aftershave products. New analyses indicate that these products have either very high concentrations of alcohol, or toxic contaminants. "During the past decade we have been investigating reasons for the very high death rate among Russians," said Martin McKee, professor of European ...

Ancient anthropoid origins discovered in Africa

...thropoid activity patterns." According to Simons, analyses of the teeth of the two species clearly place them as members of a group called parapithecoids, known as "stem" anthropoids because they constitute the species of early creatures from which the subsequent "crown" anthropoid line arose."The finding of...

Molecular cabal contributes to stroke damage

... oxygen, and analyzed the molecular effects. Their analyses revealed that such deprivation triggered NMDARs, which in turn activated an important cell switch called CaMKII. This enzyme, they found, acts on a particular ASIC, called ASIC1a, to greatly enhance its sensitivity to the acid induced by ischemia. Th...

Embryonic stem cells accrue genetic changes

Human cerebellum and cortex age in very different ways

...of molecular and cell biology at UC Berkeley. "Our analyses suggest that the different functions of different regions of the brain influence how they age, and that we can learn about functional variation and evolution by studying gene expression changes with age." The researchers used data from gene chips to...
