Women in high-income medical education positions still paid less than men

Thu, 07/05/2015 - 12:19pm
The existence of gender-based wage gaps in many occupations continues to be a hot-button topic in social and political debates. While much attention has been focused on medium- and lower-wage positions, some studies have shown that wage disparities extend to high-wage, high-prestige positions. According to a new study, women who serve as directors of internal medicine residency programs are paid less than their male counterparts.

Mobile tracking application may help users meet vitamin D Requirements

Thu, 07/05/2015 - 12:17pm
Vitamin D is essential for the maintenance of bone health and may be implicated in other chronic diseases, as well as immunity, but adults in Canada are consistently deficient in dietary vitamin D, by nearly 400 international units per day (IU/d) on average. Coupled with low vitamin D synthesis from the sun during fall and winter at Canadian latitudes, tracking intake of vitamin D is vital for those lacking the nutrient. In a new article, a group of researchers examined the validity of a mobile application for tracking vitamin D and calcium intake.

Potential for a more personalized approach to womb cancer

Thu, 07/05/2015 - 12:17pm
Traditionally, patients with endometrial cancer -- cancer of the womb lining -- have their disease risk classified using a combination of clinical and tissue characteristics, including their age and the growth and invasion of their tumor. Now high-risk womb cancer patients can be genetically profiled to allow them to receive more appropriate treatment, researchers have demonstrated.

When the baby comes, working couples no longer share housework equally

Thu, 07/05/2015 - 12:17pm
When highly educated, dual-career couples have their first child, both spouses think the baby increases their workloads by equal amounts -- but a new study suggests that's not true. Detailed results show that the mother takes on the lion's share of extra work. The results were especially surprising because before the baby was born, these couples were sharing household chores relatively equally.

New developments in personalized medicine could save billions of dollars in improved health

Thu, 07/05/2015 - 1:17am
Personalized medical interventions to prevent heart disease could generate $114 billion worth of heath gains in United States, experts say. These interventions tailor medical treatment to the individual characteristics of each patient, according to their susceptibility to a particular illness. But it goes beyond just targeting therapies at individuals who are ill; it includes the ability to identify those at highest risk of developing a disease, and who would benefit most from prevention measures.

Warm-blooded fishes swim faster and farther than cold-blooded counterparts

Wed, 06/05/2015 - 8:43pm
Marine scientists have long known that some species of fish possess a unique physiological characteristic -- a web of arteries and veins lying very close together -- that enables them to raise their internal temperatures higher than that of the water surrounding them. Now, a new study has demonstrated that species possessing the ability to warm their core -- a process called endothermy -- are able to swim two and a half times faster than those whose body temperature doesn't change.

Solomon Islands dolphin hunts cast spotlight on small cetacean survival

Wed, 06/05/2015 - 8:42pm
A new study on the impact of 'drive-hunting' dolphins in the Solomon Islands is casting a spotlight on the increasing vulnerability of small cetaceans around the world. From 1976 to 2013, more than 15,000 dolphins were killed by villagers in Fanalei alone, where a single dolphin tooth can fetch the equivalent of 70 cents -- an increase in value of five times just in the last decade.

What drives the evolution of bird nest structures?

Wed, 06/05/2015 - 8:42pm
How to protect your chicks from predators? Build a dome over them! There is tremendous diversity among the nests of birds, in nest location, structure, materials, and more, but we know very little about the forces that shaped the evolution of this incredible variety. A new study finds that domed-shaped nests arose as a result of species transitioning to nesting on the ground, where the risk from predators is greater.

Vulnerable grassland birds abandon mating sites near wind turbines

Wed, 06/05/2015 - 8:42pm
Shifting to renewable energy sources has been widely touted as one of the best ways to fight climate change, but even renewable energy can have a downside, as in the case of wind turbines' effects on bird populations. In a new paper, a group of researchers demonstrate the impact that one wind energy development in Kansas has had on Greater Prairie-Chickens (Tympanuchus cupido) breeding in the area.
