Televised direct-to-consumer advertising for testosterone therapies increased across US metropolitan areas between 2009 and 2013, and exposure to these ads was associated with greater testosterone testing, new use of testosterone therapies, and use without recent testing, according to a study published by JAMA.
With fracking, scientists have calculated the expected level of capillary rise with the Lucas-Washburn equation, a mathematical model whose earliest parameters were first devised nearly a century ago. The challenge, however, is that that the equation has not been completely accurate in predicting the actual rise observed in nano-capillary laboratory experiments. Researchers studying this deviation describe their findings this week in the journal Applied Physics Letters.
Cooking pasta chemically changes how the proteins and starches interact, making noodles sticky and springy. Therefore, what you do -- or don't do -- to the cooking water can change the edible result. With a little chemistry know-how, you can serve up a delectable al dente pasta instead of a an unappetizing ball of noodles.

Two studies published by JAMA examine the adverse effects and quality of life as reported by men with localized prostate cancer who chose treatment, observation or active surveillance.
A new study led by UNC Lineberger Comprehensive Cancer Center researchers identifies distinct patterns of side effects for modern-day prostate cancer treatments that patients could use to guide their choices.
Faced with the negative quality-of-life effects from surgery and radiation treatments for prostate cancer, low risk patients may instead want to consider active surveillance with their physician, according to a study released Tuesday by the Journal of the American Medical Association.
Longer-term follow-up of a randomized trial found strong evidence for the lack of benefit of prenatal DHA supplementation on IQ in children at 7 years of age, according to a study published by JAMA.
In just a few years, researchers have achieved remarkable power conversion efficiency with materials with perovskite crystal structure, comparable with the best photovoltaic materials available. Now, researchers have revealed the physics for how an important component of a perovskite solar cell works -- a finding that could lead to improved solar cells or even newer and better materials. They describe their experiments in this week's issue of the journal Applied Physics Letters.
With both tourism and casual 'hookup' sex on the rise among college-age adults, there's an urgent need for gender-sensitive and age-appropriate sexual health campaigns that are tailored to young women's motivations for taking sexual risks while traveling, a new study by University of Illinois scholar Liza Berdychevsky suggests.
Yale scientists have developed an ultra-thin coating material that has the potential to extend the life and improve the efficiency of lithium-sulfur batteries, one of the most promising areas of energy research today.
