In a new study, pioglitazone reduced the risk for progression from impaired glucose tolerance to type 2 diabetes by 72% as compared with placebo. However, the drug was linked to significant edema and weight gain. Ralph A. DeFronzo, MD, and colleagues recruited 602 adults with IGT to study whether pioglitazone (Actos, Takeda) could reduce the [...]

Premature babies born at 23 weeks should not be resuscitated because their chances of surviving are so slim, according to an NHS official. Dr Daphne Austin explains her logic on BBC Radio 5 live: “There is sufficient evidence to suggest that we’re [currently] doing more harm than good. “Are we confident that we are providing [...]

“Electrical activity produced by the brain has a lot more information than we realized,” says researcher William Bosl, PhD, of Children’s Hospital Boston, in a news release. “Computer algorithms can pick out patterns in those squiggly lines that the eye can’t see.”

“The brain might have to reallocate resources to help with hearing at the expense of cognition,” says the lead researcher, Frank R. Lin, M.D., an ear surgeon at Johns Hopkins Hospital in Baltimore. That may explain in part why straining to hear conversations over background noise in a loud restaurant can be mentally exhausting for anyone, hard of hearing or not, he adds.

Scientists have invented a ballistic new way to treat burns and skin abrasions – shoot them with a stem cell gun. The gun – a sterile syringe that loads into a spraying nozzle – releases a patient’s own stem cells, generated from a piece of healthy skin, which can immediately begin repairing the skin. Amazing [...]

Scientists have sequenced the entire genome of Daphnia pulex, a small crustacean commonly used as a model organism for basic biological function studies, and revealed the largest number of genes of any animal genome. The paper, published last week in Science, reports that Daphnia has a total of 30,907 genes, significantly more than the 23,000 [...]

Vaccines prevent cancer? Some vaccinations routinely given to children, such as those for hepatitis B and polio, may lower the risk of certain cancers, like leukemia. Comparing 2,800 cases of childhood cancer in Texas to more than 10,000 healthy individuals, researchers found that children born in counties where the hep B vaccine was common were [...]

That was two years ago. Since that time, the Morgan Stanley executive decided to make some changes and reverse his diabetes. Although his doctor recommended he go on medication to control his illness, Legg took a different approach. Instead of meds, he began to exercise every day and changed his diet, cutting out alcohol, fatty foods and watching his carbs.

British researchers used a so-called “closed-loop insulin delivery system” or artificial pancreas, in 10 pregnant women with Type 1 diabetes and found it provided the right amount of insulin at the right time, maintained near normal blood sugar, and prevented dangerous drops in blood sugar levels at night.

You’ve no doubt heard about the Food and Drug Administration’s investigation of the “possible association” between breast implants and a rare form of cancer known as anaplastic large cell lymphoma, or ALCL. And you’ve heard the media reaction (and possibly concerned friends or relatives or coworkers or…) Now let’s hear from the folks who implant those implants.

Science is our most potent invention because it has given us a method to keep reinventing it. All our collective knowledge and expertise (that’s science) began with relatively simple arrangements of information. The simplest organization was the invention of the fact. Facts became codified not by science, but by the European legal system in the 1500s. In court lawyers had to establish agreed-upon observations as evidence that could not shift later. Science adopted this useful innovation. Over time, the novel ways in which knowledge could be ordered increased. This complex apparatus for determining the factual correctness of information, and relating it to old knowledge, is what we call science.

Scientists have partially reversed age-related degeneration in mice, an achievement that suggests a new approach for tackling similar disorders in people.
By tweaking a gene, the researchers reversed brain disease and restored the sense of smell and fertility in prematurely aged mice. Previous experiments with calorie restriction and other methods have shown that aspects of aging can be slowed. This appears to be the first time that some age-related problems in animals have actually been reversed.
