Researchers predict infinite genomes

...n-genome is more than mere syntax. The concept has real implications for molecular biology. Many important pathogens--including those responsible for influenza, Chlamydia, and gastrointestinal infections, all under study at TIGR--contain multiple strains with specific genomes. By bringing a pan-genome per...

Hopkins scientists uncover 'tags' that force proteins to cell surface

...elp us force proteins to the surface, which offers real hope for overcoming these hurdles." Laboratory studies in which the tags might be used to force a protein of interest to the cell surface are likely to be widely used fairly quickly, but Li cautions that any potential clinical applications will requ...

Organic farms produce same yields as conventional farms

...nd agriculture, concludes, "Organic farming offers real advantages for such crops as corn and soybeans." Pimentel is the lead author of a study that is published in the July issue of Bioscience (Vol. 55:7) analyzing the environmental, energy and economic costs and benefits of growing soybeans and corn org...

Naturally occurring asbestos linked to lung cancer

Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development

...s of seconds," said Melikyan. "How this happens in real life is hard to say. "But our model," he added, "is likely to apply to any virus such as HIV that fuses with the cell membrane and shares the same fusion proteins, so it certainly provides a new target. Also, existing drugs can be re-evaluated to pi...

UCSD study clarifies insulin's role in blocking release of energy in patients with type II diabetes

...scope and watch how the live cell activates PKA in real time. The PKA is normally activated inside the adipocyte cell, the major site of energy storage in the body where many aspects of metabolism are controlled. There, energy is stored in the form of triglycerides, commonly known as fat. If a person is o...

Unweaving amyloid fibers to solve prion puzzles

...--something that no one had done before him with a real prion. To do this, Krishnan took a variety of yeast prion strains and modified them in such a way that if particular designated regions came into contact with each other, they would emit a fluorescent signal, allowing him to map the pattern by which...

Researchers create functioning artificial proteins using nature's rules

...t of natural proteins," Dr. Ranganathan said. "The real test will be to put them back into a living organism such as yeast or fruit flies and see how they compete with natural proteins in an evolutionary sense." Other UT Southwestern researchers involved in the work are lead authors Michael Socolich, HHM...

Hanging baskets of sex and death help fruit growers

...es manage to have an actual encounter with another real moth. This results in direct contamination of eggs laid by the pest or contamination of the site where the moth lays its eggs. The larvae are killed after eating the virus on the egg or plant surface. This brings two key benefits to fruit growers: A...

From a Few Wild Ancestors, a Citrus Cornucopia

... known, until recently, just what the collection’s real breadth and scope were. “There were redundancies and gaps in the collection that needed to be sorted out,?says Krueger, “and some specimens had even been mislabeled.?Mistakes are costly for curators, since a few missing or added letters can change t...

No small feat: First ever gene therapy success for muscular dystrophy achieved

...percent of body weight, gene therapy can only have real therapeutic benefit if it is able to reverse genetic defects in every cell of the body's 600 muscle groups. By using a miniature gene, similar in function to the one defective in CMD, and applying a newly developed method for "systemic" gene deliver...

Toxic flood lifts lid on common urban pollution problem

...d to Hurricane Katrina. Though these are certainly real problems, it's also highly likely that the stagnant waters are contaminated because they've soaked up "legacy" pollutants that accumulated during normal conditions on the city's streets, sidewalks, roofs and other impermeable surfaces, Sansalone said...

Progress on HIV/AIDS significant but insufficient

Women now accounted for about half of all people living with HIV worldwide, but they were also the most courageous and creative champions in that fight. How the international community fared in the fi...

Evolution of life on Earth may hold key to finding life in outer space

"All known living organisms on Earth share various biochemical properties, such as the same genetic code, the same major amino acids in proteins, and ?with minor exceptions ?the use of DNA or occasionally RNA as genetic material," Fox sa...

Computers close in on protein structure prediction

The encouraging results come from a refinement of a sophisticated computer modeling program called Rosetta, first developed several years ago in ...

Sensor web simulation investigates technique to improve prediction of pollution across the globe

"Our goal here is improve our ability to monitor and assess the Earth's environment," Talabac added. "With the sensor web, policy and decision makers will have access to the most useful and timel...

Researchers report breakthrough against world’s deadliest viruses

...ctive in monkeys is a promising indicator of their real potential for use in humans. "When you see the tragedies these viruses cause, it's very frustrating that we can't do more to help people," said Dr. Feldmann, who (along with Dr. Jones and others from PHAC) has been providing on-site rapid diagnostic...

UCLA scientists reveal how Nipah virus infects cells

...ing that the receptor is the same doorway that the real Nipah virus enters to infect these cells. "We now can screen for small molecules that will block viral entry via Ephrin B-2 and develop them as therapeutic drugs," said Lee. "Because pigs are particularly susceptible to Nipah infection, public healt...

NASA satellite data provides rapid analysis of Amazon deforestation

While this study highlights the challenges of monitoring deforestation and the use of MODIS data in the Amazon, it also shows that similar MODIS analyses could form t...

Less virulent strains of avian influenza can infect humans

They commented, however, that very s...
