'Best of both worlds' -- Targeting a single gene could inhibit bone decay and stimulate bone growth

...asts, which cause bone decay. But there is also at least one that stimulates osteoblasts, enhancing bone formation. A combined treatment will not only prevent the occurrence of osteoporosis, but also make the quality of bone even better. "Our discovery proves that inhibiting osteoclasts while simultane...

Artificial cornea offers better results for infants, some blind patients

...how much he or she could see, every child could at least see fingers held at an arm's length, and some children improved to 20/30 vision. "Finally, we seem to have a method in hand to improve the vision of these children, many of whom have endured several surgeries that have failed," said James Aquavell...

Study highlights new and cheaper way to treat heroin addiction

...or drug users, which have proved controversial not least because of the high costs involved. In contrast to methadone –which comes in liquid not tablet form ?dihydrocodeine is much easier to store and comes under less stringent regulations because it is not as toxic and less likely to cause a fatal over...

Rising ocean temperatures, pollution have oysters in hot water

... 300 species reliant on oyster reefs, including at least 12 species important for their commercial or recreational value, such as blue crabs, sheepshead, croaker and stone crab," Sokolova said. "Some of these species, such as blue crabs, use oyster beds and reefs as nursery areas and as feeding grounds." T...

Pattern of human Ebola outbreaks linked to wildlife and climate

...ibodies to Ebola. Some people had been exposed at least three years before the first known Ebola outbreak in Gabon, while others lived in regions where no known epidemics had occurred. In 2003, Lahm was able to track down six of the people whose blood samples indicated that they had been exposed to the E...

Successful lung cancer surgery not enough to break nicotine dependence in many smokers

...d to lung cancer surgery patients, he added. At least seven studies of non-small cell lung cancer patients have shown that many of these patients continue smoking despite the risk, but the rate of relapse ranged from a low of 13 percent to about 60 percent. This study was unique in that it sought to inc...

Leading reason for corneal transplants comes into focus

... Hopkins have discovered the genetic origins of at least one form of Fuchs corneal dystrophy, FCD, the leading reason for corneal transplantation in the United States. In one form or another, FCD's trademark deterioration of the cells covering the clear, outermost lens of the eye affects more than 4 perce...

Slow brain waves play key role in coordinating complex activity

...ecause slow firings are detected when the brain is least active, while rapid firings accompany activity, neuroscientists think that information in the brain is carried by the high frequencies. Until recently, scalp recordings could detect gamma waves only up to 70 firings per second, but in 1998 researche...

Brain regions do not communicate efficiently in adults with autism

... Half the adults had autism and all had IQs of at least 80. The EEGs, which measure the activity of hundreds of millions of brain cells, were collected with an array of 124 electrodes while the people were seated and relaxed with their eyes closed for two minutes. The researchers found patterns of h...

Engineering faculty at McMaster are working closely with their colleagues in health sciences on this research, as well as with researchers at the Universities of Toronto, Wa...

Mass vaccination unnecessary in the event of a large bioterrorist US smallpox attack

...mallpox vaccination ended in 1972, which leaves at least 43 percent of the U.S. population unvaccinated, Longini said. Research suggests that those previously vaccinated may still have substantial residual immunity although, if infected, they could still transmit the virus to others. Those most vulnerable ...

Tiny bones rewrite textbooks

...The fact that even one land mammal lived there, at least 16 million years ago, has put paid to the theory that New Zealand's diverse prehistoric bird fauna had evolved there because they had no competition from land mammals.
