Scientists Replicate Hepatitis C Virus in Laboratory

...infectious disease has suffered from the lack of a robust in vitro model system,?says T. Jake Liang, M.D., Chief of the Liver Diseases Branch of the NIDDK and co-author of the study. “Our model system produced viral particles that have all the properties of the whole virus. This evidence together with an an...

Essential mangrove forest threatened by cryptic ecological degradation

...ition of freshwater management that once sustained robust irrigation-based civilizations. The researchers show that, increasingly, the magnitude of these modern irrigation projects has been such that entire river basins have been diverted to those of other rivers. Whereas these projects certainly develop th...

Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

...and I thought we should do some studies to see how robust the idea is," Estes said. The team of researchers, accompanied by a small army of student assistants, conducted extensive surveys on the islands for several weeks each summer over three years. They surveyed dozens of islands from one end of the arch...

Kinovate Life Sciences Launches Nittophase?High Performance Solid Support For Oligonucleatide Synthesis

...pplications. “Kinovate Life Sciences aims to be a robust partner to both oligonucleotide manufacturers and drug development companies by providing NittoPhase? a new support with superlative performance at a significantly reduced unit cost. In this way we see considerable potential to make it possible for p...

HIV vaccine trial breaks ground for future research

...ies, and an HIV vaccine will be found only through robust public and private investment as well as a well-informed public and scientific community. ...

Gray wolves maintain the food chain in winter

.... Crucially, Wilmers and Getz's study shows that a robust food chain - including this still embattled top predator - may be even more important as ecological conditions deteriorate. ### Citation: Wilmers CC, Getz WM (2005) Gray wolves as climate change buffers in Yellowstone. PLoS Biol 3(4): e92. ...

Alzheimer's cognitive decline slowed

...ssue of a study participant who had died and found robust growth of extensions from the dying cholinergic cells near the site of growth factor gene delivery. Cholinergic neuron loss is a cardinal feature of Alzheimer's disease, a progressive brain disorder affecting memory, learning, attention and other cog...

Microbial forensics: The next great forensic challenge

Building a protein name dictionary from full text: a machine learning term extraction approach

...ty names. It is also computationally efficient and robust to noise commonly found in full text material. We use the method to create a protein name dictionary from a set of 80,528 full text articles. Only 8.3% of the names in this dictionary match SwissProt description lines. We assess the quality of the di...

Scientists discover global pattern of big fish diversity in open oceans

... bode well for the future health of open oceans. A robust portfolio of different species is a key to maintaining our supply of fish in the long term and the ability of these living resources to rebound from environmental changes. Open Ocean Hotspots Coral reefs have long been known for their rich diversit...

Breakthrough: Scientists create world's tiniest organic particles

...ecause they involved baking, etching or processing robust metals and such with solvents that would have destroyed far more fragile organic matter such as genes or drugs. The new method avoids harsh treatment but also allows formation of uniform particles in any shape designers choose ?spheres, rods, cones,...

Fluorescing lab worms signal longer life spans

...ld ultimately be able to find what makes an animal robust to many different insults." Johnson authored a milestone paper in 1988 showing that mutating a single gene in roundworms could double their life span -- the first evidence that the lifespan of an animal could be increased by genetic alteration. Sinc...

A new molecule discovered in the battle between plants and disease

...egulare than wild-type plants, evidenced by a more robust leaf and root growth upon infection. ProAtPep1 belongs to a seven member gene family in Arabidopsis with tissue-specific paralogs that exhibit differential expression profiles. Orthologs of the proAtPep1 gene have been identified in important crop sp...

Nose odors and mouth odors: The brain distinguishes

...n the nose demonstrates that olfactory referral is robust and cognitively impenetrable." To begin to penetrate the neural cause of olfaction's duality, the researchers devised the first experiments to directly compare the same odorants introduced through the nose and the mouth. "Although several studies h...

Nanowires can detect molecular signs of cancer, scientists find

...ht, however, provide the information necessary for robust diagnosis of disease ?[and] detection of markers associated with different stages of disease pathogenesis could further facilitate early detection." While initial rounds of cancer testing today identify only whether or not cancer is present, nanowir...

Geckos: It's not always about sex

...horse and a donkey," said Kearney. "Mules are very robust animals, but they cannot reproduce." Kearney's research suggested that the hybrid forms of Bynoe's geckos could not only reproduce through parthenogenesis, but were "super tough," just like a mule. Kearney shipped Bynoe's geckos from Sydney, Austral...

Researchers find molecule that inhibits regrowth of spinal nerve cells

...hen we achieve those three things, then we'll have robust regeneration of injured nerves." Other Center for Developmental Biology researchers involved with the study were Dr. Mark Lush, postdoctoral research fellow, and Dr. Q. Richard Lu, assistant professor. Dr. Mario Romero, assistant professor of neurol...

Traditional models underestimate extinction rates

... continue to mount, biologists will need ever more robust methods to estimate extinction risk. Unfortunately, field biologists typically can't generate the large, high-quality datasets that led to the precise predictions reported here. Conservation efforts will depend on developing methods of generating rel...

Ancient DNA confirms single origin of Malagasy primates

...om additional taxa will overturn this increasingly robust hypothesis." Yoder said the researchers' results support the close relationship of sloth lemurs (Palaeopropithecus) to living indriids, but Megaladapis does not show a sister-group relationship with the living genus Lepilemur. "The classification of...

Stem cells bring fast direct improvement, without differentiation, in acute renal failure
