    The water system that helped Angkor rise may have also brought its fall

    At the medieval city of Angkor, flooding after decades of scant rainfall triggered a devastating breakdown of the largest water system in the preindustrial world, new evidence suggests.

    Intense monsoon rains bracketed by decades of drought in the 1400s set off a chain reaction of failures in Angkor’s interconnected water network, computer simulations indicate. The climate-induced...

    This reflective paint could keep sunbaked buildings cool

    A new polymer-based paint that reflects nearly all incoming sunlight could help keep buildings, cars, airplanes and other sunbaked structures cool.

    This polymer paint, described online September 27 in Science, can be applied to various surfaces, including plastics, metals and wood. It also could be fashioned into recyclable tarpaulins for covering homes, cars or other enclosed spaces....

    Can science build a better burger?

    This isn’t as extreme as if the federal government had decided to regulate time travel. But it’s almost as surprising. The U.S. Food and Drug Administration is taking the first step toward rules for growing nutritious, delicious, juicy meat in labs, not farms.

    The notion of growing, say, just the beef instead of the whole cow has been floating around since at least the 1890s. This sci-fi...

    A new material harnesses light to deice surfaces

    A new material that converts light into heat could be laminated onto airplanes, wind turbines, rooftops and offshore oil platforms to help combat ice buildup.

    This deicer, called a photothermal trap, has three layers: a top coating of a ceramic-metal mix that turns incoming light into thermal energy, a middle layer of aluminum that spreads this heat across the entire sheet — warming up...

    A filter that turns saltwater into freshwater just got an upgrade

    Smoothing out the rough patches of a material widely used to filter saltwater could make producing freshwater more affordable, researchers report in the Aug. 17 Science.

    Desalination plants around the world typically strain salt out of seawater by pumping it through films made of polyamide — a synthetic polymer riddled with tiny pores that allow water molecules to squeeze through, but...

    As waters rise, coastal megacities like Mumbai face catastrophe

    Each year when the monsoon rain sheets down and the tides swell over coastal Mumbai, Saif shutters his soda shop on Juhu Beach and takes shelter up in the rafters. Still, the water invades through the roof and over the concrete floors, sometimes reaching as high as the freezers full of ice cream.

    For 36-year-old Saif, the coastal megacity’s chronic flooding is stressful. “What would...

    A big analysis of environmental data strengthens the case for plant-based diets

    From beef to beer, coffee to chocolate, there are environmental costs in what humanity chooses to eat and drink. Now a new study that quantifies the impact on the planet of producing and selling 40 different foods shows how these choices make a difference.

    Agricultural data from 38,700 farms plus details of processing and retailing in 119 countries show wide differences in environmental...

    Grapevines are more drought-tolerant than thought

    The latest word on the grapevine is promising.

    During more than a decade of observation, grapevines in Napa, Calif., and Bordeaux, France, never reached lethal levels of dehydration from seasonal drought, researchers report online January 31 in Science Advances. Plant ecophysiologist Guillaume Charrier, at the French National Institute for Agricultural Research in Paris, and colleagues...

    Worries grow that climate change will quietly steal nutrients from major food crops

    2017 was a good year for worrying about nutrient losses that might come with a changing climate.

    The idea that surging carbon dioxide levels could stealthily render some major crops less nutritious has long been percolating in plant research circles. “It’s literally a 25-year story, but it has come to a head in the last year or so,” says Lewis Ziska, a plant physiologist with the U....

    Chong Liu one-ups plant photosynthesis

    Chong Liu, 30Inorganic chemistUCLA

    For Chong Liu, asking a scientific question is something like placing a bet: You throw all your energy into tackling a big and challenging problem with no guarantee of a reward. As a student, he bet that he could create a contraption that photosynthesizes like a leaf on a tree — but better. For the now 30-year-old chemist, the gamble is paying off.
