On a wing and a prayer - Alaska researchers seek clues to bird flu

...according to the World Health Organization, is the possibility that the present situation could give rise to an influenza pandemic in humans akin to the 1918 "Spanish Flu." On Friday, WHO warned that China is not rigorously following up on a recent deadly H5N1 outbreak among wild birds. The 1918 influenza pande...

Emerald Spectre haunts Ontario's ash forests

...of the firewall ?but MacIsaac doesn't rule out the possibility that beetles jumped the ash-free zone. The study notes that scientists still need to determine the maximum flight potential of adult borers. In Michigan, the borer was reported at 29 new sites in 2004. New infestations were also reported in Ohio and...

Gene therapy reverses genetic mutation responsible for heart failure in muscular dystrophy

... has antibodies to human AAVs, there is always the possibility that the effectiveness of this form of gene therapy may be blunted by a host immune response. However, Dr. Xiao is optimistic that will not be the case. "The AAV-8 we used in this study was isolated from monkeys, so we are very hopeful it will be ab...

Living anti-HIV gel shows early promise

...n's disease. Berger points out, however, that the possibility of genes transferring from the GM bacteria to other microbes in the body carries a potential medical risk that must be assessed. Although the approach has produced promising results in mice, trials on monkeys exposed to HIV or the primate equivalent...

New antifreeze protein found in fleas may allow longer storage of transplant organs

... from a person's system very quickly, reducing the possibility of harmful antibodies forming." An ancient species related to modern insects, snow fleas are also known as "springtails" because of the distinctive springing organ under their abdomen which allows them to leap hundreds of times their one-millimeter ...

Stem cells' electric abilities might help their safe clinical use

...eart cells derived from human ESCs, suggesting the possibility of transplanting unlimited supplies of healthy, specialized cells into damaged organs. "We do not want to be taking any chances of tumor formation. Based on our previous research, we therefore decided to explore the existence of ion channels in plur...

Building a better mouse model of lung cancer: FHIT counts

...t 1 issue of Cancer Research, open the door to the possibility of new, targeted treatments that could be offered at the very first signs of lung cancer, when the possibility of a cure is most likely. Creating the new mouse was basically a matter of FHIT ?the gene that form...

New vaccine platform may fight infections with causes from influenza to bioterrorism

... Dr. Kolls said. "This new technology opens up the possibility that therapeutic vaccine response can be achieved in populations of patients who face the greatest risk ?children, the immunosuppressed and the elderly. Although not discussed in the paper, Dr. Kolls says the vaccine approach is worth investigating ...

Life in deadly conditions

... The frugality of Natronomonas pharaonis, with the possibility of simplifying the nutrient solution, opens new possibilities for experimentally investigating the metabolic network. The data we thus acquire make up an important foundation for developing and testing metabolic models in the framework of systemic bi...

Delaware scientists make significant advance in study of small RNAs

...sis using MPSS when Green approached him about the possibility of sequencing small RNAs using the MPSS technology. "We knew MPSS could work in sequencing small RNAs but we were not sure how interesting the outcome would be," Meyers said. "But, as soon as we received the first complete data set, we quickly saw t...

New technique multiplies life span in simple organisms

... organisms lacking both SCH9 and SIR2, raising the possibility that the mutations that cause human cancers can be delayed or prevented," Longo said. "Notably, mutations that increase the activity of human homologs of the yeast SCH9 and RAS2 genes play central roles in many human cancers." Homologs are genes des...

Tsunami + 1 year: Reviving exhausted fisheries should trump replacing boats, gear, experts say

...s they are seeking to help. For fishers, the grim possibility that efforts to rebuild might actually send their communities on a downward path to economic misery is very real." WorldFish says data on fish stocks is lacking for the specific places most affected by the tsunami but suspects the situation mirrors ...

Ancient trans-Atlantic swarm brought locusts to the New World

...ad bodies, then take off and keep flying." Another possibility is that among the millions of swarming locusts were a few exceptional insects that somehow managed to survive the flight. Lovejoy adds that high-altitude winds would have been essential for the swarm's flight. There is a modern-day example of this ph...

Novel protein complex enables survival in hostile environment

..." Mukhopadhyay said. The challenge of the latter possibility attracted the group to the topic. They decided to see if methanogens that live in an environment where the early earth conditions are preserved ?deep-sea hydrothermal vents ?still have the ancient detoxification system. Inside a hydrothermal vent, s...

New GM mosquito sexing technique is step towards malaria control, report scientists

...ign gene into the mosquito genome. This raised the possibility that genetic manipulation could be used as a control method in mosquito populations. Professor Crisanti adds: "Although there have been a number of control programmes to eradicate malaria, none of these have been entirely successful, and many have a...

Clocking in Pillow Time without the Pillow

...y, Sam Deadwyler and colleagues have explored this possibility by giving dog-tired rhesus monkeys a drug shown to improve the functioning of alert brains. They found that sleepy monkeys taking the drug performed tasks better and had increased metabolic activity in several regions of their brains. This suggests t...

Noise And Delays Explain Why Some Genes Oscillate In Activity

...y, Sam Deadwyler and colleagues have explored this possibility by giving dog-tired rhesus monkeys a drug shown to improve the functioning of alert brains. They found that sleepy monkeys taking the drug performed tasks better and had increased metabolic activity in several regions of their brains. This suggests t...

UCLA discovery will aid in treatment of patients with a deadly brain cancer

...ed by molecular testing. The study also raised the possibility that patients whose tumors lack the genetic variations in the molecular signature could possibly be treated with drugs to make them more sensitive to EGFR blockers. Of the 8,000 to 10,000 glioblastoma patients diagnosed each year, about 10 to 20 per...

Common viruses may cause cancer

...apy or in other clinical applications owing to the possibility that such viruses might cause cancer. The idea that aberrations in the number or structure of chromosomes can spur tumor formation is more than a century old. Such aberrations--known collectively as "aneuploidy"--arise in two principal ways: as a co...

OHSU discovery sheds light into how stem cells become brain cells

...replace the lost dopamine-producing cells. Another possibility would be the replacement of lost or damaged motor neurons in patients who have suffered brain or spinal cord damage. This research was funded in part by the Medical Research Foundation of Oregon, the National Institute's of Health and the Christoph...
