Healthier diets possible in low-income, rural communities in America
A team of investigators implemented a two-year intervention study in low-income, rural areas where a disproportionately higher risk of overweight and obesity habits among children persists, leading to increased risk of diabetes and heart disease in adulthood.

Disrupting an antioxidant pathway prevents heart disease caused by reductive stress
A deficiency of the antioxidant response protein Nrf2 downregulates antioxidant activity to delay harmful cardiac remodeling.

Fish genital shape linked to predation
When predators lurk nearby, male Bahamas mosquitofish (Gambusia hubbsi) change mating strategies, rejecting elaborate courting rituals for more frequent and sometimes forceful encounters with females.

Med schools improve conflict-of-interest standards, yet much room for progress remains
US medical schools have made significant progress to strengthen their management of clinical conflicts of interest, but a new study demonstrates that most schools still lag behind national standards.

Predators vs. alien: European shrimps win predatory battles with an American invader
British and Canadian ecologists have discovered that native European shrimps resist the invasion of lakes and rivers by an American shrimp, by killing and eating the colonists.

Uniformity: The secret of better fusion ignition
One of the ways to achieve thermonuclear fusion is through a controlled reaction between two light variants of hydrogen, called deuterium and tritium.

Behavioral therapy provided during dialysis sessions may combat depression among kidney failure patients
Behavioral therapy provided chair-side to kidney failure patients while they're undergoing dialysis may help fight depression and improve patients' quality of life, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology.
