Working memory is genetic
People who can juggle a lot of information at the same time they should thank their parents, suggests new research. Working memory is used to store information in mind simultaneously, and some people have better memories than others. Gabriëlla Blokland University of Queensland in Brisbane, Australia, and colleagues scanned the brains 319 twins who were carrying out the tasks of the working memory. Twin Sisters performed together more brains similarly than twin, suggesting that working memory is strongly influenced by genetic factors. The results are displayed in the July 27 Journal of Neuroscience. – Laura Sanders
Shorter telomeres, cancer, breast
Cut gradually turns off the ends of chromosomes can lead to progressively earlier breast cancer in families with inherited risk of disease. Women with breast cancer, mutations of the genes BRCA1 and BRCA2, or from other Inherited mutations also had shorter telomeres — protective covers on chromosomes — than women in the public service, July 28, in PLoS Genetics researchers report in the Spanish National Cancer Research Center in Madrid. In families with hereditary breast cancer, breast cancer, the daughter of a younger age developed and had a shorter telomeres than their mothers. Measurement of Telomere length could help doctors better screening design plans. — Tina Hesman Saey
Quality over quantity in the conservation of avian influenza
The elderly provide for effective combating of avian influenza antibodies, but often do not make enough to keep the virus in check. This may explain why influenza vaccine work well in older people, researchers from Stanford and the University of Chicago report in the August Journal of clinical investigation. Study suggests that doctors, you can specify that generated the appropriate number of vaccinated patients safe from influenza antibodies. — Tina Hesman Saey
Diagnostics on CSI: Siberia
Thought that was a long time to come back for your lab tests consider the case of a man in Siberia. The man died in the late 17th century or beginning of the 18th century, but French and Russian scientists are only now finding how to diagnose the disease, which have killed him. DNA from the man's teeth and the lungs reveals that he was infected with a bacterium, which causes whooping cough. Teeth with other long-dead Siberians have shown that they were infected with bacteria that cause pneumonia and dysentery, researchers report online on July 13, in PLoS ONE. New technique may help scientists figure out where the disease had killed people in different times in history. — Tina Hesman Saey
