While studying sediments in the Bay of Bengal, an international team finds evidence dating back millions of years that catastrophic events likely toppled fresh trees from their mountain homes on a long journey to the deep sea. The discovery may add to models of the Earth's carbon cycle.
Read moreThe secret of classic Belgian beers? Medieval super yeasts!
An international team of scientists has discovered that some of the most renowned classic Belgian beers, including Gueuze and Trappist ales, are fermented with a rare and unusual form of hybrid yeasts. These yeasts combine DNA of the traditional ale yeast, Saccharomyces cerevisiae, with that of more stress-resistant feral yeasts such as Saccharomyces kudriavzevii.

Our brains have a remarkable ability to pick out one voice from among many. Now, a team has uncovered the steps that take place in the brain to make this feat possible. Today's discovery helps to solve a long-standing scientific question as to how the brain's listening center can decode and amplify one voice over others. It also stands to spur development of hearing-aid technologies and brain-computer interfaces that more closely resemble the brain.
Read moreClosures affect 1 in 8 pharmacies in the US
Despite an overall increase in the number of pharmacies in the U.S. from 2009 to 2015, one in eight pharmacies, or 9,654, had closed during this period. Independent pharmacies in both urban and rural areas were three times more likely to close than chain pharmacies.
Read moreReplacing coal with gas or renewables saves billions of gallons of water
The transition from coal to natural gas in the US electricity sector is reducing the industry's water use, research finds. For every megawatt of electricity produced using natural gas instead of coal, the water withdrawn from rivers and groundwater drops by 10,500 gallons, and water consumed for cooling and other plant operations and not returned to the environment drops by 260 gallons. Switching to solar or wind power could boost these savings even more.
