Detection of DNA on nanotubes offers new sensing, sequencing technologies

...rough the system," Jeng said. "Furthermore, optics yield high-resolution signals and require a relatively simple setup. And, because our detection setup is in solution, we can sense in a natural biological environment." ...

Mining for gems in the fungal genome

... metabolite gene clusters are already beginning to yield potentially useful medical agents. The team found an anti-tumor agent never before seen in Aspergillus nidulans. "It's just one of many [secondary metabolites to discover]," says Keller. "It's just the tip of the iceburg." Thirty or so secondar...

Climate change: The rice genome to the rescue

... tolerant of higher temperatures that can maintain yield and quality when extreme temperatures occur," Dr. Sheehy said. "We also need rice varieties that can take advantage of higher levels of CO2 in the atmosphere, rice that is vigorous enough to recover quickly from extreme weather events and disasters, ...

Intelligently designed molecular evolution

...ould evolve along a specific functional pathway to yield a desired molecular product, then introduce it into microbes for mass production. In addition to synthesizing therapeutic drugs, other possible applications would include flavors, fragrances and nutraceuticals. "Our ultimate goal is to be able to p...

Clawed frog helps Fanconi anemia research make leaps

...th frogs for more than two years, will continue to yield discoveries that may someday lead to a treatment of certain cancers and for Fanconi anemia, a devastating disease that primarily affects children. The lab already joined forces with other labs to isolate several of the dozen genes known to exist in t...

Cellular scale drug delivery from the inside out

...cell to produce a certain desired product, but the yield may drop significantly." By using externally controlled nanospheres, Lin explains that it may be possible to sequentially release genes, chemical markers and other materials within cells in order to track what happens and what specific changes take ...

Picking particles faster than one at a time

...o meet this challenge, but until now even the best yield more than 30 percent false positives -- either poor-quality images of particles or something else altogether, like debris or background noise. Therefore "a human still has to go through them and pick out the good ones," Adiga says. Adiga and his co...

Gene expression profile helps predict chemotherapy response in ovarian cancer patients

...first time that two profiles have been combined to yield such a powerful result in this disease." One of the most difficult types of cancer to treat, advanced ovarian cancer accounts for approximately 26,000 new cases and 16,000 deaths in the U.S. each year. "Being able to identify the expression pattern...

Jefferson scientists identify gene defect leading to abnormal skin development and cancer

...ers of water from tanks holding 35,000 larvae. The yield was less than a milligram, or 35 millionths of an ounce. Much of the work in isolating and purifying the pheromone was performed by Sorensen's graduate student Jared Fine, while Vadims Dvornikovs, Christopher Jeffrey and Feng Shao in Hoye's lab were ...

Leading lampreys to slaughter: Pheromone for scourge of Great Lakes identified

Adult stem cells aid recovery in animal model of cerebral palsy

...thesized to reside in the divergent regions should yield interesting clues to the identity of genes that drive speciation, and the mechanism by which they do so. This is a significant finding in the field of speciation research: in terms of methodology, this study shows that DNA microarrays can be used to...

Islands in the Genome Promote Speciation

University of Arizona plant scientists to unravel maize genome

...s on to develop corn varieties that produce higher yield and better quality with less water on less land," ... agriculture. Other improvements aim at increasing yield and nutritional value and optimizing the properties crucial for grain products such as flour, noodle...

Scientists pinpoint inflammation gene

...said the discovery of SEPS1 and its function could yield new approaches for inhibiting inflammation, perhaps through medications that regulate SEPS1. An expected search for other genes that influence SEPS1 also could lead to other potential areas for drug intervention. Researchers studying diseases impac...

Ancient anthropoid origins discovered in Africa

...ecies consist of tiny teeth and jaws, whose shapes yield critical clues about the species whose mouths they once occupied. For example, a tooth root from the species Biretia megalopsis is truncated, indicating that it had to make room for the larger eyesocket of a nocturnal animal. "These finds seem to in...

GM crop that holds on to its seeds offers higher yields

Researchers have found a way of boosting the yield of a major crop by stopping its seedpods from burs...eams' plants that do not shatter their seeds could yield crops that are well suited for the warmer climates of most developing countries. Link to abstrac...

UF study first to quantify validity of DNA I.D. tool using marine snails

..., the researchers determined that thresholds would yield a 17 percent error rate. Besides its benefits to ecology, DNA barcoding has some forensic applications, Meyer said. One applied use already being employed is identifying the bird species responsible when a carcass damages an airplane engine, he sai...

DNA size a crucial factor in genetic mutations, study finds

...e new traits that actually benefit the organism or yield no effect. These small-scale changes, collectively called genetic drift, play an important role in evolution, as does natural selection. To make their DNA bases, Kool started with a molecule similar to thymine-called an analog-and made five differen...
