    Prosecco production takes a toll on northeast Italy’s environment

    Sorry to burst your bubbly, prosecco lovers, but skyrocketing demand for the sparkling wine might be sapping northeastern Italy’s vineyards of precious soil — 400 million kilograms of it per year, researchers report in a study posted online January 10 at bioRxiv.org.

    That’s a lot of soil, but not an anomaly. Some newer vineyards in Germany, for example, have higher rates of soil loss,...

    This honeybee parasite may be more of a fat stealer than a bloodsucker

    Tests with fake bee larvae reveal that a “vampire” mite attacking honeybees may not be so much a bloodsucker as a fat slurper.

    The ominously named Varroa destructor mite invaded North America in the 1980s, and has become one of the biggest threats to honeybees. Based on research from the 1970s, scientists thought that the parasitic mites feed on the bee version of blood, called hemolymph...

    A new way to genetically tweak photosynthesis boosts plant growth

    A genetic hack to make photosynthesis more efficient could be a boon for agricultural production, at least for some plants.

    This feat of genetic engineering simplifies a complex, energy-expensive operation that many plants must perform during photosynthesis known as photorespiration. In field tests, genetically modifying tobacco in this way increased plant growth by over 40 percent. If...

  • 50 years ago, screwworm flies inspired a new approach to insect control

    Screwworm fly upsurge 

    Screwworms, the first pest to be eliminated on a large scale by the use of the sterile male technique, have shown an alarming increase, according to U.S. and Mexican officials…. The screwworm fly lays its eggs in open wounds on cattle. The maggots live on the flesh of their host, causing damage and death, and economic losses of many millions of dollars. —...

    Hemp fields offer a late-season pollen source for stressed bees

    VANCOUVER — Fields of hemp might become a late-season pollen bonanza for bees.

    Industrial hemp plants, the no-high varieties of cannabis, are becoming a more familiar sight for American bees as states create pilot programs for legal growing. Neither hemp nor the other strains of the Cannabis sativa species grown for recreational or medicinal uses offer insects any nectar, and all rely on...

    Plants engineered to always be on alert don’t grow well

    A tiny weed that slithers up through sidewalk cracks is helping scientists understand the sacrifices that plants make to protect themselves from pests.

    Most plants combat insects and other herbivores by sending out bitter chemicals through their leaves. Now by studying thale cress (Arabidopsis thaliana), a commonly found member of the mustard family, researchers found that energy spent...

    Add beer to the list of foods threatened by climate change

    Beer lovers could be left with a sour taste, thanks to the latest in a series of studies mapping the effects of climate change on crops.

    Malted barley — a key ingredient in beer including IPAs, stouts and pilsners — is particularly sensitive to warmer temperatures and drought, both of which are likely to increase due to climate change. As a result, average global barley crop yields could...

    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 map reveals the causes of forest loss worldwide

    If a tree falls in the forest, will another replace it?

    Of the roughly 3 million square kilometers of forest lost worldwide from 2001 to 2015, a new analysis suggests that 27 percent of that loss was permanent — the result of land being converted for industrial agriculture to meet global demand for products such as soy, timber, beef and palm oil. The other 73 percent of deforestation...

    How plant microbes could feed the world and save endangered species

    One fine Hawaiian day in 2015, Geoff Zahn and Anthony Amend set off on an eight-hour hike. They climbed a jungle mountain on the island of Oahu, swatting mosquitoes and skirting wallows of wild pigs. The two headed to the site where a patch of critically endangered Phyllostegia kaalaensis had been planted a few months earlier. What they found was dispiriting.

    “All the plants were gone,”...
