Novel therapy combinations gain ground in treating hepatitis

...s has become a worldwide health problem, affecting millions of people in the U.S. and abroad. Researchers are experimenting with combinations of anti-inflammatory medicines like interferons to improve hepatitis symptoms. In research presented today at Digestive Disease Week® 2006 (DDW), new combinations of ...

NHGRI announces latest sequencing targets

...matophyte fungi are highly communicable and infect millions of people worldwide leading to costs of approximately $400 million a year for treatment alone. The dermatophytes to be sequenced are Trichophyton rubrum, Microsporum canis and Microsporum gypseum, all of which will be sequenced to a high-density geno...

Seeing the serpent

...e," Isbell said. In South America, monkeys arrived millions of years before venomous snakes, and show less specialization in their visual system compared with Old World monkeys and apes, which all have good vision, including color. Having evolved for one purpose, a good eye for color, detail and movement la...

Elephants, large mammals recover from poaching in Africa's oldest national park

..., and Tanzania, the tourism business has generated millions of dollars, not only for the parks but also for local communities throughout the region. "Virunga Park will be the key to any tourism industry in Congo with its large mammals, gorillas, active volcanoes and biodiversity. It is clear that Congo need...

Scientists aim to thwart use of flu as bioweapon

... deadly ?witness the 1918 Spanish flu which killed millions of people ?and with modification, they can be made even more deadly," said Hulin Wu, Ph.D., professor in the Department of Biostatistics and Computational Biology and director of the modeling center. Wu's colleague, Martin Zand, M.D., Ph.D., co-direc...

DOE JGI finishes 100th microbial genome

...robes range in size from typically five to tens of millions of bases, several microbes could be sequenced in one day. However, the sequencing process, in order to meet rigorous quality standards and to satisfy the demands of the scientific community, is an iterative one, requiring six- to eight-times coverag...

Device effective in zapping the pain out of migraines

...efore it starts may be the next form of relief for millions of people who suffer from the debilitating disease. Results of a study found that the experimental device appears to be effective in eliminating the headache when administered during the onset of the migraine. The study, led by the Ohio State Uni...

Queensland scientists identify molecule that links both sides of the brain

... of the corpus callosum. The corpus callosum has millions of individual nerve fibres. If these fibres fail to reach their correct targets in the opposite hemisphere, people can suffer from epilepsy, and experience some degree of mental retardation. "Our study is the first to identify a growth molecule tha...

Study reveals how ADHD drugs work in brain

Although millions depend on medications such as Ritalin to quell symptoms of attention deficit hyperactivity disorder (ADHD), scientists have struggled to pinpoint how the drugs work in the brain. But new work at the University of Wisconsin-Madison is now starting t...

Pest control research leads to pain control discovery

...on, Acoxia. However, the class of drugs benefits millions of sufferers from inflammation and pain, Hammock said. The UC Davis study may mean a solution to the dilemma of whether to use the drugs. "Combination therapies have long been used to treat inflammation while reducing side effects," Schmelzer wrote...

New MRI technique shows emphysema in asymptomatic smokers

...ted States have been diagnosed with emphysema, and millions more are in the early stages of the disease before signs and symptoms appear. Smoking cigarettes triples the risk of developing the disease. The researchers had 19 volunteers inhale a special kind of "hyperpolarized" helium before they performed two...

Discovery may speed forest biotechnology

...red that the same genes had been conserved through millions of years of separate evolution and also performed similar functions in aspen trees. To their surprise, however, the researchers found that the CO/FT combination also controlled the cessation of vegetative tree growth in the fall ?something that Arab...

Study reveals mass migration of mormon crickets driven by hunger, fear

...th America. Throughout their seasonal migration, millions of Mormon crickets (relatives of locusts and grasshoppers) cover more than 50 miles of ground, destroying farmland and causing hazardous driving conditions along the way. The research team, led by Dr. Stephen J. Simpson, conducted field observation...

MIT researchers build tiny batteries with viruses

...o grow the electrode material, we can easily clone millions of identical copies of the virus to use in assembling our batteries. "For the metal oxide we chose cobalt oxide because it has very good specific capacity, which will produce batteries with high energy density," meaning it can store two or three tim...

Nanopore method could revolutionize genome sequencing

...ng a person's genome would take several months and millions of dollars with current DNA sequencing technology, the researchers say that the new method has the potential to usher in a revolution in medicine. "Current DNA sequencing methods are too slow and expensive for it to be realistic to sequence people...

Evolution of 'irreducible complexity' explained

...ient genes and their functions evolved hundreds of millions of years ago. We found that complexity evolved piecemeal through a process of Molecular Exploitation -- old genes, constrained by selection for entirely different functions, have been recruited by evolution to participate in new interactions and new...

Inside rocks, implications for finding life on Mars

... So, we can see how the fossils have degraded over millions of years, and learn what are real biological features and what has been changed over time." His research is published in the January issue of the journal Astrobiology, in which he reports confocal microscopy results of the ancient fossils. (He publi...

Amber reveals ecology of 30 million year old spiders

...y of ancient spiders trapped in amber more than 30 millions years ago. The study of fossilised spiders from the Baltic (Poland) and the Dominican (Caribbean) regions has revealed new insights into the ecologies of spiders dating back to the Cenozoic period. It is the first time ancient spiders from differen...
