Energy drinks may give young sports teams an edge, study says

Consuming energy drinks during team sports could help young people perform better, a study suggests.

Sports scientists found that 12-14 year olds can play for longer in team games when they drink an isotonic sports drink before and during games.

Researchers at the University of Edinburgh measured the performance of 15 adolescents during exercise designed to simulate the physical demands of team games such as football, rugby and hockey.

Experts question claim that Alexander the Great's half-brother is buried at Vergina

The tomb was discovered during the excavation of a large mound – the Great Tumulus – at Vergina in 1977. Along with many treasures including ceremonial military equipment, bronze utensils, silver tableware, and gold wreaths, the tomb contained two sets of skeletal remains. Those of a man were found in a gold casket in the main chamber and those of a woman in a smaller gold casket in the second chamber. Both individuals had been cremated and evidence of a wooden funerary house containing a pyre was also found near the tomb.

Micro-RNA determines malignancy of lung cancer

Cancer becomes life-threatening when tumor cells start leaving their primary site. They travel through the lymph and blood streams to other tissues where they grow into metastases. This transition to malignancy is associated with characteristic changes in the cancer cells. The activity of several genes is reprogrammed and, thus, the production of proteins anchoring cells to a tissue is reduced. On the other hand, the amount of surface markers which make a cancer cell mobile increases.

Young, male, testosterone-fueled CEOs more likely to start or drop deals: UBC study

Too much testosterone can be a deal breaker, according to Sauder School of Business researchers at the University of British Columbia. Their paper, to be published in the INFORMS journal Management Science on September 10, shows that young CEOs with more of the steroidal hormone in their system are more likely to initiate, scrap or resist mergers and acquisitions.

NOAA designates the eastern North Pacific basking shark a 'species of concern'

NOAA's Fisheries Service has designated the eastern North Pacific basking shark, a "species of concern" because it has suffered a dramatic decline in population despite decreasing fishing pressure. The label "species of concern" may be given to a species when there are concerns regarding the population status.

NIH study shows how insulin stimulates fat cells to take in glucose

Using high-resolution microscopy, researchers at the National Institutes of Health have shown how insulin prompts fat cells to take in glucose in a rat model. The findings were reported in the Sept. 8 issue of the journal Cell Metabolism.

Institute for Aging Research study finds indoor and outdoor fall are different for the elderly

BOSTON—The risk factors for indoor and outdoor falls for older adults are different, according to a new study by the Institute for Aging Research of Hebrew SeniorLife, an affiliate of Harvard Medical School, a fact that is often missed when the two are combined and may affect how falls prevention programs are structured.

Smoking damages men's sperm and also the numbers of germ and somatic cells in developing embryos

Two new studies have shed more light on how smoking may damage fertility, and give further weight to advice that mothers and fathers-to-be should stop smoking before attempting to conceive. The research is published online in Europe's leading reproductive medicine journal Human Reproduction today (Wednesday 8 September).

Ghostwritten articles overstate benefits of hormone replacement therapy and downplay harms

The first academic analysis of the 1500 documents unsealed in recent litigation against the pharmaceutical giant Wyeth (now part of Pfizer) reveals unprecedented insights into how pharmaceutical companies use ghostwriters to insert marketing messages into articles published in medical journals.

International consortium contribute to turkey genome sequencing

An international consortium of researchers has completed the majority of the genome sequence of the domesticated turkey, thanks in part to the efforts of Virginia Tech faculty members.

The research team will publish "Multi-Platform Next-Generation Sequencing of the Domestic Turkey (Meleagris gallopavo): Genome Assembly and Analysis" in the journal PLoS Biology (Public Library of Science) on Sept. 7, 2010.

Compared to recent flu strains, 2009 H1N1 infection had lower risk of most serious complications

An analysis of data from influenza cases in Wisconsin indicates individuals with 2009 H1N1 infections were younger than those with H3N2 (2007-2008), and that the risk of most serious complications was not higher in adults or children with 2009 H1N1 compared with recent seasonal strains, according to a study in the September 8 issue of JAMA.

Young pneumococcal vaccine age linked to increased risk of getting multiresistant strain

Infants who received heptavalent pneumococcal conjugate vaccination (PCV-7) at 2, 4, and 11 months were more likely than unvaccinated controls to have nasopharyngeal (in the nasal passages and upper part of the throat behind the nose) acquisition of pneumococcal serotype 19A, a leading cause of respiratory pneumococcal disease, according to a study in the September 8 issue of JAMA.

Researchers find diet-induced obesity accelerates leukemia

LOS ANGELES (September 7, 2010) – The first study to demonstrate that obesity can directly accelerate the progression of acute lymphoblastic leukemia (ALL) has been conducted at The Saban Research Institute of Childrens Hospital Los Angeles and will be published in Cancer Prevention Research, on October 5, 2010. Obesity has been associated with an increased incidence of many cancers, including leukemia, but it has been unknown whether the increase in incidence was a direct effect of obesity or associated with genetic, lifestyle, health, or socio-economic factors.
