The 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.

How the brain dials up the volume to hear someone in a crowd  

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.

Replacing 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 For every megawatt of electricity produced using natural gas instead of coal, the water withdrawn from rivers and groundwater drops by 10,500 gallons, and water consumed for cooling and other plant operations and not returned to the environment drops by 260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.

Plant physiology will be major contributor to future river flooding  

Researchers describe the emerging role of ecophysiology in riparian flooding. As an adaptation to an overabundance of carbon dioxide in the atmosphere, trees, plants and grasses constrict their stomatal pores to regulate the amount of the gas they consume, a mechanism that limits the release of water from leaves through evaporation. This saturates soils and causes more efficient run off and river flooding.
