Dartmouth researchers have found that tweens (preadolescents aged 10-14) who participate in a coached team sport a few times a week or more are less likely to try smoking. Their findings on the relationship between extracurricular activity and health risk behaviors are reported in "The relative roles of types of extracurricular activity on smoking and drinking initiation among tweens," which was recently published in Academic Pediatrics.

Sell-side analysts lean towards high valuation companies for comparison, Rotman study shows.

Toronto – Brokerage-based analysts have a tendency to benchmark companies they are researching against others in the same category whose stock is already expensively-priced, shows a study from the University of Toronto's Rotman School of Management.

A gene known to repair DNA damage in healthy cells may also provide new insights about treating a genetic disorder of the bone marrow, Caltech researchers say.

This finding was published in the May 15 print edition of the journal Cell Cycle.

WASHINGTON -- When it comes to being perceived as effective leaders, women are rated as highly as men, and sometimes higher - a finding that speaks to society's changing gender roles and the need for a different management style in today's globalized workplace, according to a meta-analysis published by the American Psychological Association.

Barnacles might seem like a given part of a seasoned ship's hull, but they're literally quite a drag and cause a ship to burn more fuel. To prevent these and other hangers-on from slowing ships down, scientists are developing a sustainable paint ingredient from plants that can repel clingy sea critters without killing them. The report appears in the ACS journal Industrial & Engineering Chemistry Research.

In modern dentistry, amalgam fillings have become unpopular. Instead, white composite materials are more commonly used, which at first glance can hardly be distinguished from the tooth. The majority of these composites are based on photoactive materials that harden when they are exposed to light. But as the light does not penetrate very deeply into the material, the patients often have to endure a cumbersome procedure in which the fillings are applied and hardened in several steps.

A type of cell that builds mouse hearts can renew itself, Johns Hopkins researchers report. They say the discovery, which likely applies to such cells in humans as well, may pave the way to using them to repair hearts damaged by disease — or even grow new heart tissue for transplantation.

The University of Maryland School of Medicine (UM SOM) and Novavax, Inc. (NASDAQ: NVAX) today announced that an investigational vaccine candidate developed by Novavax against the recently emerged Middle East Respiratory Syndrome Coronavirus (MERS-CoV) blocked infection in laboratory studies. UM SOM and Novavax also reported that a vaccine candidate against Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV) developed by Novavax on a similar platform also inhibited virus infection.

New evidence shores up findings that whey protein, which is found in milk and cheese, could have health benefits for people who are obese and do not yet have diabetes. The study, which appears in ACS' Journal of Proteome Research, examined how different protein sources affect metabolism.

Molluscs are invertebrates that make up one of the most numerous groups in the animal kingdom. They are everywhere, from great heights of over 3,000m above sea level to ocean profundities of over 5,000m deep, in polar and tropical waters and they tend to be common elements on coastlines around the world. Within this animal group are found the nudibranchs, characterized among other things, for not having shells and being brightly coloured. This colouring alerts their predators to their toxicity. Within this group, in turn, we can find the Aeolidiidae family.

Asking NHS staff about what affects whether they would recommend their organisation for family and friends is an important source of intelligence for improving quality and safety of care, says a new study.

This finding by researchers in the Universities of Leicester, Aberdeen, and Bristol has been published in a paper, 'The friends and family test: a qualitative study of concerns that influence the willingness of English National Health Service staff to recommend their organisation', in the Journal of the Royal Society of Medicine.

TORONTO -- A possible therapeutic target for control of blood glucose in the treatment of type 2 diabetes and obesity has been identified by Dr. Anita Johswich and her colleagues. Their findings were published in Journal of Biological Chemistry, online April 17, 2014.

If you pull up a soybean or bean plant and shake off the dirt, you might see odd swellings or bumps, like rheumatic finger joints, on its roots. Inside the cool, soil-covered bumps are bacteria that are making nitrogen with the help of an enzyme, something chemical factories can do only with the help of a catalyst and at high temperature and pressure.

Decades after the genomics revolution, half of known eukaryote lineages still remain unstudied at the genomic level--with the field displaying a research bias against 'less popular', but potentially genetically rich, single-cell organisms.

This lack of microbial representation leaves a world of untapped genetic potential undiscovered, according to an exhaustive survey conducted by UBC researchers of on-going genomics projects. The survey results are published in the May issue of Trends in Ecology and Evolution.

Toronto, ON, Canada, April 30, 2014 – A new technique that brings CT imaging into the operating room will allow surgeons to precisely demarcate and remove small sub-centimeter lung nodules, leaving as much healthy tissue as possible, according to Raphael Bueno, MD, of Brigham and Women's Hospital in Boston. His team is presenting the results of this late-breaking research at the 94th AATS Annual Meeting in Toronto, ON, Canada on April 30, 2014.
