'Freak' ocean waves hit without warning, new research shows
Mariners have long spoken of 'walls of water' appearing from nowhere in the open seas. But oceanographers have generally disregarded such stories and suggested that rogue waves - enormous surface waves that have attained a near-mythical status over the centuries - build up gradually and have relatively narrow crests.
Fracking plays active role in generating toxic metal wastewater, Dartmouth study finds
The production of hazardous wastewater in hydraulic fracturing is assumed to be partly due to chemicals introduced into injected freshwater when it mixes with highly saline brine naturally present in the rock. But a Dartmouth study investigating the toxic metal barium in fracking wastewater finds that chemical reactions between injected freshwater and the fractured shale itself could play a major role.

A new spin on star-forming galaxies
Australian researchers have discovered why some galaxies are "clumpy" rather than spiral in shape--and it appears low spin is to blame.
Elevated testosterone levels may raise risk of uterine fibroids
Women who have high levels of both testosterone and estrogen in midlife may face a greater risk of developing benign tumors on the uterus called uterine fibroids than women with low levels of the hormones, according to a new study published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
Fossils enrich our understanding of evolution
Our understanding of evolution can be enriched by adding fossil species to analyses of living animals, as shown by scientists from the University of Bristol.
Researchers elucidate network of genes that control when puberty begins

Biophysicists have discovered why the bacteria that cause tuberculosis (TB) are naturally somewhat resistant to antibiotics known as fluoroquinolones.
Gamma rays from distant galaxy tell story of an escape
A flare of very high-energy gamma rays emitted from a galaxy halfway across the universe has put new bounds on the amount of background light in the universe and given astrophysicists clues to how and where such gamma rays are produced.
Study: Eliminating cost for colorectal cancer screening doesn't improve screening rates
Making colonoscopy available at no cost to eligible Medicare beneficiaries under the Affordable Care Act (ACA) did not increase the number of people in this target population who regularly undergo the procedure, says a new large scale national study from University Hospitals Case Medical Center Seidman Cancer Center.

East Antarctic Ice Sheet has stayed frozen for 14 million years, Penn team reports
Antarctica was once a balmier place, lush with plants and lakes. Figuring out just how long the continent has been a barren, cold desert of ice can give clues as to how Antarctica responded to the effects of past climates and can perhaps also indicate what to expect there in the future as Earth's atmospheric concentration of carbon dioxide grows.
