Researchers discover new gene responsible for brittle bone disease

...ed gene and one normal gene, they have one-in-four chance of having a child with osteogenesis imperfecta. Funding for the research came from the National Institutes of Health, the Baylor College of Medicine Developmental Disabilities Research Center, and the Shriners of North America. Others institutes p...

Long-term cancer risk follows stem cell transplant recipients

...em with a compatible donor's stem cells offers the chance of cure for a disease that otherwise has a high mortality rate with non-transplant therapies. While the procedure can be lifesaving, it is associated with serious short-term adverse effects, such as mucostitis, infections, and liver vascular obstruct...

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

...he moles' performance dropped down to the level of chance ?the same as their performance with no-scent trails. In order to see if this capability was limited to the star-nosed mole or if other small semi-aquatic mammals also have it, Catania captured some water shrews and began testing them. He found that...

On the golf tee or pitcher's mound, brain dooms motion to inconsistency

...ficant movement are novel. Predators never get the chance to catch and kill prey in exactly the same fashion and in exactly the same conditions. "The nervous system was not designed to do the same thing over and over again," Churchland says. "The nervous system was designed to be flexible. You typically f...

Ocean temperature predicts spread of marine species

...d. "For many animals, the larval phase is the only chance for babies to get away from parents. Dispersal prevents inbreeding; for some species, this is a time to move from breeding ground to habitat where they'll mature," she said. But less than 1 percent of larvae survive dispersal. They are consumed by...

Parental genes do what's best for baby

...e to produce large offspring to give them the best chance of survival and carry on their gene line. But large offspring require greater maternal investment, so females will try to impose their genetic stamp so that smaller young are born. “The idea that imprinting evolves because of conflict between male...

Three-in-one virus killer prevents common, often fatal infections

...us have had little success ?there is an 80 percent chance of death following the development of adenovirus. "Not only were patients prevented from getting these infections after transplant, but those patients who had infections responded to the T-cell therapy and did not require any other treatment," sai...

UWM brain research supports drug development from jellyfish protein

Parasitic plants sniff out hosts

...rch was random and the location of a host simply a chance encounter. After four days, when the plant was growing flat on the filter paper, the researchers measured the direction of the shoot. The researchers report that 80 percent of the dodder plants grew onto the side of the filter paper nearest the tom...

With record resolution and sensitivity, tool images how life organizes in a cell membrane

...ack and forth. When you're in two dimensions, your chance of bumping into something else is a lot higher than when you're in three dimensions. This is the idea of the rafts. You get one of these pieces of grease stuck on you, and now you become associated with the membrane and you find yourself in one of th...

Test reveals effectiveness of potential Huntington's disease drugs

...ng of a person with Huntington's have a 50 percent chance of inheriting it. More than 250,000 people in the United States have the disorder or are at risk for it. There is no cure, but several drugs are used or are being tested to relieve symptoms or slow Huntington's progression. The disease affects...

Eminent inventor of DNA fingerprinting gains new recognition

Smokers invite to test vaccine against nicotine addiction

...moking is less rewarding. That gives the smoker a chance to change the behavioral and social factors that also influence smoking," said Victor Reus, MD, principal investigator for the study at UCSF. Because immune antibodies remain in the body for some time, Reus said it is hoped that the vaccine also wi...

Acidity in the brain could hold the key to stroke treatment

Current techniques often only enable one to see damage once it is too late to intervene."

Sleep deprivation doubles risks of obesity in both children and adults

Professor Cappuccio says: "The 'epidemic' of obesity is paralleled by a 'silent epidemic' of reduced sleep duration with short sleep duration linked to increased risk of obesity both in adults and in children.These tr...

Combined treatment extends life expectancy for lung cancer patients

With radiation alone, overall survival rates were as follows: one year ?57 percent two years ?36 percent three years ?21 percent With thermal ablation and radiation, they were significantly h...

Mussels evolve quickly to defend against invasive crabs

...present north of mid-coast Maine. "This set up a chance to look at populations that had been exposed to the predators for varying lengths of time," says Freeman. "We wanted to know, how is it that these mollusks can recognize a crab that is historically not present in North America?" Freeman exposed mus...

Brighter future for giant panda?

The scientists anticipate that these results are likely to be replicated in other key reserves indicating that there may now be many...

New egg freezing technique offers hope to hundreds of women

... hundreds of oocytes in order to have a reasonable chance of obtaining a child, but by using the technique of Dr Kuwayama and his colleagues, it will be possible to achieve the same rates of success with 10-20 frozen-thawed oocytes as with fresh oocytes. This is a major improvement, and for the first time, ...
