Diabetic nerve therapy shows 'striking' results

...ing nerve damage. Progression to amputation is not inevitable but is always a threat. Problems may also occur in other organs, including the heart, kidneys, sex organs, eyes and digestive tract. The incidence of diabetes, a condition in which the amount of glucose in the blood is too high, is increasing drama...

Environmental lessons from tsunami as world's coastal population doubles

... insight into handling extreme coastal disasters - inevitable as the world's coastal population is set to double by 2030 and global warming continues to exacerbate extreme weather conditions. The research team from Australia, US, Sweden and UK, led by Dr Neil Adger of the University of East Anglia, is calling ...

Tiny roundworm's telomeres help scientists to tease apart different types of aging

The continual and inevitable shortening of telomeres, the protective "caps" at the end of all 46 human chromosomes, has been linked to aging and physical decline. Once they are gone, so are we. But there are more ways than one to grow old. Researchers at Salk Institute for Biol...

Retinal scans eyed for New Mexico show cattle

...rd and comfortable with ID technology because it's inevitable that it's coming to New Mexico," Encinias said. When the idea of mandatory cattle identification was introduced several years ago, cattle producers were concerned about expense, inconvenience and loss of privacy. But experts stress the importance ...

Polymer gel can block toxic leakage problem in gene therapy

...njection needle. Yuan said such viral escapes are inevitable since the needle's diameter is 30 times larger than the width of the microvessels that supply the tumor with blood. The needle is also wider than the spaces between each of those vessels, he added. The first author of the British Journal of Cancer s...

Scientists use stem cells to grow cartilage

...UK's increasing ageing population there will be an inevitable increase in problems created by people living longer. Although doctors have been able to carry out joint replacements for a number of years, it has not possible to replace the worn out cartilage. By replacing the cartilage it may be possible to avoid...

Gene Expression in the Aging Brain

...erns was the direct result of selection, or was an inevitable consequence of some other difference in brain evolution. The patterns seen in this study also provide a starting point for understanding the network of genetic changes in aging, and may even reveal targets for treatment of neurodegenerative diseases....

Navigating the brain for sense of direction as paradigm for higher cognitive functions

Switching to new anti-bacterial targets: Riboswitches

... antibiotics. According to the researchers, it is inevitable that bacteria will evolve and that the drugs we use to cure bacterial infections will eventually become ineffective. While it is often possible to alter existing drugs slightly, they suggest that a longer term and more attractive solution is to creat...

New U. of Colorado at Boulder flu chip may help combat future epidemics, pandemics

...atural catastrophes, she said. "A flu pandemic is inevitable since the virus continually mutates and is naturally spread by migratory birds. Whether this year or 10 years from now, it is important to be prepared for such an event." Most experts agree that preparations for a flu pandemic include early identif...

Screening blood for West Nile virus

...to ensure that the best policy is in place for the inevitable 2006 season. WNV can be detected in blood samples by recently developed and approved tests. These tests detect some but not all cases of contamination with the virus. This means that WNV infections that could result from contaminated blood products...

Confidence in memory performance helps older adults remember

...ts are more likely to judge their forgetfulness an inevitable fact of aging or even a warning sign of Alzheimer's disease, leading to anxiety and despair. Those who don't use adaptive strategies for remembering often have the expectation that there is nothing they can do to improve memory. The study's results ...

Contrary to common wisdom, scientist discovers some mammals can smell objects under water

...les come into contact with an object, it is almost inevitable that odorant molecules will mix with the air and be drawn into the nose when the bubble is inhaled." Just because the moles are getting whiffs of interesting odors underwater doesn't necessarily mean they smell them. So Catania devised some additi...

Statin treatment improves spatial memory in mouse models of Alzheimer's

...s for the gene for beta amyloid protein, making it inevitable that they develop an Alzheimer’s like disease as they age. In fact, they lose their memory by nine months of age. These animals, together with regular mice without the beta amyloid genes, were acclimated for one week, with as much food and water as t...
