(University of Hawaii at Manoa) Patches of coral reef are often surrounded by very large 'halos' of bare sand that are hundreds to thousands of square meters. Two recently published studies and a third feature story led by Elizabeth Madin, assistant research professor at the University of Hawai'i at Mānoa, shed light on these enigmatic features that are visible from space.

(Ohio State University) New research on tube anemones is challenging everything that evolutionary biologists thought they knew about sea animal genetics. The mitochondrial DNA of the tube anemone, or Ceriantharia, is a real head scratcher, from its unexpected arrangement to its previously unimagined magnitude.

(PSE Healthy Energy) More than 80 percent of all waste from Pennsylvania's oil and gas drilling operations stays inside the state, according to a new study that tracks the disposal locations of liquid and solid waste from these operations across 26 years. Numerous human health hazards have been associated with waste from oil and gas extraction, including potential exposure to compounds known to cause cancer.

(Ecological Society of America) Researchers use GPS to track the timing and patterns of giant tortoise migration over multiple years. The tortoises often take the same migration routes over many years in order to find optimal food quality and temperatures. The timing of this migration is essential for keeping their energy levels high, and climate change could disrupt a tortoise's ability to migrate at the right time.

(Carnegie Mellon University) Researchers sought to estimate the effects of exposure to lead in topsoil on the cognitive ability of 5-year-olds in the United States. The study found that higher lead in topsoil significantly increases the probability that 5-year-old boys will have cognitive difficulties but does not seem to affect 5-year-old girls. The researchers found the adverse effects in boys even in U.S. counties where the government considers the levels of lead concentration in the soil to be low.

(Geological Society of America) Steps and pools are among the most stable and functionally important features in the mountain river landscape. Their stability is important for dissipating stream energy, withstanding ordinary floods and resisting erosion, and regulating the flow and sediment dynamics feeding into lowland areas.

(International Institute for Applied Systems Analysis) According to an independent study released today by the International Institute for Applied Systems Analysis (IIASA) and the Council on Energy, Environment, and Water (CEEW), more than 674 million Indian citizens are likely to breathe air with high concentrations of PM2.5 in 2030, even if India were to comply with its existing pollution control policies and regulations.
