Beating heart tissue produced in laboratories
sea-maid submitted, created time 6 months 3 weeks (www.nature.com)
An international team of researchers has used stem cells to create heart tissue, complete with beat. By treating embryonic stem cells with growth factors, they coaxed them into becoming cardiovascular progenitor cells, which then developed into cardiomyocytes, vascular smooth muscle cells, and endothelial cells, which together form blood vessels. When injected into the hearts of mice with induced heart disease, they improve heart function.
What this discovery does not include is fibroblasts, the cells that form the framework of the heart. 
What is the mechanisms of work stress and coronary heart disease?

As known, in mordern times, people are suffering more and more work stress, which would hurt our heart, But wether the inevitability exsist between them is not known. Recently, a new study suggested work stress may be an important determinant of CHD among working-age populations, which is mediated through indirect effects on health behaviours and direct effects on neuroendocrine stress pathways.
Embryonic stem cells coaxed into key heart cells

Scientists say they have coaxed human embryonic stem cells into becoming three of the major cell types in the human heart, and they improved cardiac function when transplanted into mice. The findings, published in the journal Nature on Wednesday, showed that scientists can efficiently make different kinds of human heart cells for use in basic and clinical research. The researchers said that in the short term, they could be used to test how heart cells respond to different drugs
Genetic Information Nondescrimination Act poised to pass
Darkfrog submitted, created time 6 months 4 weeks (www.nytimes.com)
The U.S. Congress is preparing a bill that would forbid employers and insurance companies from denying or terminating employment or coverage based on the results of genetic tests. Federal law already prohibits group policies, such as those attained through one's employer or other organization, from discriminating using genetic information, but this bill would apply accross the board.
This bill is likely to pass, and I think it will remove one of the main fears associated with genetic testing (finally finding out that one has a 40% chance of lung cancer is still there, though).
The findings about How Stomach Tumors Form

Stomach cancer is the second most common cause of cancer-related deaths worldwide. Many people are rightly concerned about this disease. In this article, the study shows us how stomach tumors form. Stomach cancer has been shown, previously, to be correlated with chronic inflammation.
Stomach hormone turns hungry people into junkies

In this paper ,the researchers point out that stomach hormone turns hungry people into junkies.When volunteers received a dose of a natural hunger-inducing hormone called ghrelin, their brains responded to pictures of food in the same way that addicted people's brains do to cigarettes or drugs, says Alain Dagher, a neurologist at McGill University in Montreal, Canada, who led the study.
And the study also tell us that hormone has its stimulant effects and Memory improvement,mood changes.
Drinking and the Shrinking Brain

Some researchers went looking for evidence that low to moderate alcohol consumption could stave off brain problems. That is not what they found.
Nobody wants to think about their brain's shrinking. But our brains do so as we
age, by about two percent every ten year. According to a new article in the Annals of Neurology, that figure is higher for people who drink.
The authors request that people remember that the correlation that was found is between drinking and decreases in brain size, not brain function.
High-calorie diet linked to boys

Recently, the researchers in the Universities of Exeter and Oxford suggests a high-calorie diet at pregnant time--and regular breakfasts--might increase the odds of a boy. And the modern trend to opt for low calorie diets might explain why the proportion of boys is falling in developed countries.
The study, by the Universities of Exeter and Oxford, appears in the Royal Society journal Biological Sciences.
A structural–functional basis for dyslexia in the cortex of Chinese readers

This study tell us that the scientists have found different structural and functional abnormalities in dyslexic readers of Chinese, a nonalphabetic language. Compared with normally developing controls, children with impaired reading in logographic Chinese exhibited reduced gray matter volume in a left middle frontal gyrus region previously shown to be important for Chinese reading and writing.

After more than a decade of research, the first gene therapy trials in people with a rare form of blindness are under way, and experts say they are thrilled with the early findings.
U.S. company recalls about 286,000 pounds of meat

A New York company is voluntarily recalling about 286,000 pounds (129,700 kg) of fresh and frozen meat and poultry products that may be contaminated with bacteria. The meat may be contaminated with Listeria monocyotogenes bacteria, which can cause a rare but potentially fatal disease known as listeriosis.
Proteins Decide Boys Become Boys

In research that could give doctors a way to reassign sex in cases of unclear gender, scientists report this week that they have figured out why some children with genes that should make them boys are instead born as girls.
Be still my beating stem cell heart
sea-maid submitted, created time 6 months 1 week (www.newscientist.com)
There's a new recipe in the embryonic stem cell cookbook. Scientists have announced the creation of a human master heart cell, able to transform into all the different cells that make up a beating heart. In this study, the scientists have begun experiments to transform iPS cells into the heart cells.
England's neonatal service reorganisation fails to iron out regional variation in death rates

Five years after a major reorganisation of England's neonatal services, large and unexplained variations between regions in mortality among neonates still exist, concludes a new report from the House of Commons Public Accounts Committee.
Spanish scientists create extra-long-lived mice
piggy submitted, created time 4 days 5 hours (www.enews20.com)
Spanish scientists have created "super-mice" that are cancer-resistant and live up to forty percent longer, media reported Friday.
The mice were subjected to genetic engineering by researchers from the cancer research centre CNIO and Valencia University.
The key to the experiment was an enzyme called telomerase, which lengthens chromosome ends known as telomeres.
Telomerase allows cells to keep dividing and is believed to increase longevity, but it also heightens the risk of cancer
