Unique gene regulation gives chilly bugs survival advantage at bottom of the world

...d development," he said. This mechanism seems to offer the larvae protection during their two-year life span, most of which is spent encased in ice. All animals, including humans, make heat shock proteins, but normally they only do so during times of extreme physical stress. Curiously, adult midges don...

Living view in animals shows how cells decide to make proteins

... of each tissue or organ. The findings also may offer insight into a number of diseases, including cancer, in which the genetic process -- called alternative splicing -- goes awry and produces the wrong proteins, the scientists said. The scientists published the findings in the Dec. 1, 2006, issue of...

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

...mystery how that is accomplished.? These findings offer “an unexpected and elegant explanation that’s both beautiful and simple, as nature invariably proves to be.? The fundamental mechanism of transcription is conserved among cellular RNA polymerases, the researchers explained. Common features include a...

Math model predicts cancer behavior

.... Such manipulations of the microenvironment could offer new directions for cancer treatment, he said. Next up for the group are in vitro and in vivo experiments designed to test, validate and refine the mathematical model. ...

Protein structure initiative launches new resources for the scientific community

...d biological function. The Knowledgebase also will offer experimental details about each stage of the protein structure determination process, regardless of whether the structure was successfully determined. Information about current PSI proteins being solved will be listed. In addition to searching these ...

'Protecting virus' offers instant flu protection and converts flu infections into their own vaccines

... animals against various strains of flu, and could offer protection against the full range of influenza A i...uenza. It can also counter an actual infection and offer protection if given up to 24 hours after first infection (and possibly longer). Existing vaccinati...

Cities change the songs of birds

...d between city and forest birds. The findings also offer strong support for a theory known as the acoustic-adaptation hypothesis, which states that some aspects of the vocal variety of animal communication sounds are shaped by the environment. The authors point out that song divergence within a species as ...

Tiny Tampa Bay fish key to evolution of immune system

...ews prove to be basically correct, the study would offer the prospect of enhancing our understanding of the structural requirements for molecules used by the adaptive immune response to recognize and counter components of invading microbes. If so, it would provide an illustration of the potential for studi...

Intravenous gene therapy protects normal tissue of mice during whole-body radiation

... that intravenous administration could potentially offer wide-reaching protection to the public in the event of a terrorist attack since experts believe a significant number of the population would die within 30 days of receiving a large dose of radiation to the entire body. In the study, mice were used...

Scientists design simple dipstick test for cocaine, other drugs

...dvanced Science and Technology. "The new sensors offer a quick and convenient test that can be utilized by first responders or emergency room staff to quickly screen individuals for a variety of drugs and other chemicals." Lu said. Aptamers are single-stranded nucleic acids that can bind to specific mo...

Study illuminates how the plague bacteria causes disease

...h incompletely understood mechanism. The findings offer important new insight into the factors that lend Yersinia their ability to spawn disease, the researchers said. The results might also contribute to new strategies for fighting the bug. "Yersinia injects several virulence factors into its host," sai...

End of deforestation in view? Experts advance new way to size up global forest resources

... of forest area and growing stock, the researchers offer a formula to calculate atmospheric carbon being stored incrementally in the trees of a given area, knowledge critical for mitigating climate change. Says Dr. Waggoner: "A rapid forest transition at a global scale would mean that atmospheric CO2...

Small, smaller, smallest -- The plight of the vaquita

...in conservation actions, particularly in ones that offer viable socioeconomic alternatives to fishermen. Mexico has a very good record in helping endangered marine mammals to recover. There are no better examples anywhere in the world than eastern Pacific gray whales and northern elephant seals, both of...

An advanced genetic diagnostic method for multiple myeloma

... too distant future, these tests will permit us to offer each patient a treatment adapted to the genetic modifications that he or she presents, which, while they may not provide a cure for the disease, will make it possible to transform it into a chronic and asymptomatic pathology. ...

Evolution and the workaround

...ng how cells adapt to internal perturbations could offer insight into how pathogens and cancer cells mutate to evade the body’s defenses and resist treatment with drugs. The Stowers researchers used the benign budding yeast Saccharomyces cerevisiae as their model organism and deleted a key cell divisi...

Muscle and bone from an ink-jet printer

... delivery of bio-inks with an ink-jet printer will offer the Pittsburgh researchers a whole new level of complexity and control. The custom built ink-jet printer, which was developed at Carnegie Mellon, can deposit bio-inks in virtually any design, pattern, or concentration, laying down patterns on fib...

Columbia University licenses next-generation DNA sequencing technology

We are poised to offer a simple, cost effective platform that will enable many researchers and clinicians to use this next-generation DNA sequencing technology in their own laboratories." Dr. Ju is a prolific inventor of new technologies for applications in genomics usin...

Replacing insulin is top-ranked breakthrough foreseen for health in developing world

...es facing developing countries, these technologies offer real promise in the field of health. It is a young field and there's great opportunity to shape it now while it is developing." says Heather Greenwood of the Canadian Program on Genomics and Global Health. Says co-author Halla Thorsteinsdottir of t...

Geneticists discover genes that make fruit fly hybrids sterile

...sult of the mating of two different species -- may offer interesting and beneficial traits, they are usually sterile or unable to survive. For example, a mule, the result of the mating of a horse and a donkey, is sterile. Now, Cornell researchers have made the first identification of a pair of genes in an...

'Trojan Horse' agent halts bone metastasis in mice
