Researchers map the evolutionary history of oaks
Oaks have a complex evolutionary history that has long eluded scientists. New research, however, provides the most detailed account to date of the evolution of oaks, recovering the 56-million-year history that has made the oaks one of the most diverse, abundant and important woody plant groups to the ecology and economy of the northern hemisphere.
Lakes worldwide are experiencing more severe algal blooms
The intensity of summer algal blooms has increased over the past three decades, according to a first-ever global survey of dozens of large, freshwater lakes, which was conducted by Carnegie’s Jeff Ho and Anna Michalak and NASA’s Nima Pahlevan. They used 30 years of data from the Landsat 5 near-Earth satellite and created a partnership with Google Earth Engine to reveal long-term trends in summer a
Study shows a much cheaper catalyst can generate hydrogen in a commercial device
SLAC and Stanford researchers have shown for the first time that a cheap catalyst can split water and generate hydrogen gas for hours on end in the harsh environment of a commercial electrolyzer — a step toward clean, large-scale hydrogen production for fuel, fertilizer and industry.
Reading the past like an open book: Researchers use text to measure 200 years of happiness
Using innovative new methods researchers at the University of Warwick, University of Glasgow Adam Smith Business School and The Alan Turing Institute in London have built a new index that uses data from books and newspaper to track levels of national happiness from 1820. Their research could help governments to make better decisions about policy priorities.
Yale scientists help immune system find hidden cancer cells
