    Climate change might help pests resist corn’s genetic weapon

    Climate change might be great news for pests looking to munch on genetically modified crops, researchers propose.

    In particular, researchers analyzed 21 years of data from Maryland cornfields and suggest that rising temperatures might help corn earworms (Helicoverpa zea) develop resistance faster to a widespread genetically built-in crop protection.

    Some commercial varieties of...

    Changing climate could worsen foods’ nutrition

    A dinner plate piled high with food from plants might not deliver the same nutrition toward the end of this century as it does today. Climate change could shrink the mineral and protein content of wheat, rice and other staple crops, mounting evidence suggests.

    Selenium, a trace element essential for human health, already falls short in diets of one in seven people worldwide. Studies link...

    How to grow toxin-free corn

    Corn genetically engineered to make ninjalike molecules can launch an attack on invading fungi, stopping the production of carcinogenic toxins.

    These specialized RNA molecules lie in wait until they detect Aspergillus, a mold that can turn grains and beans into health hazards. Then the molecules pounce, stopping the mold from producing a key protein responsible for making aflatoxins,...

    Fleets of drones could pollinate future crops

    Eijiro Miyako gets emotional about the decline of honeybees.

    “We need pollination,” he says. “If that system is collapsed, it’s terrible.”

    Insects, especially bees, help pollinate both food crops and wild plants. But pollinators are declining worldwide due to habitat loss, disease and exposure to pesticides, among other factors (SN: 1/23/16, p. 16).

    Too many stinkbugs spoil the wine

    How many stressed-out stinkbugs does it take to spoil a batch of wine? More than three per grape cluster, new research says. 

    Stinkbugs are a pest among vintners because of the bugs’ taste for wine grapes and namesake foul smell. When accidentally harvested with the grapes and fermented during the wine-making process, the live insects can release their stink and ruin the wine (SN: 5/5/07...

    DNA points to millennia of stability in East Asian hunter-fisher population

    In a remote corner of eastern Russia, where long winters bring temperatures that rarely flicker above freezing, the genetic legacy of ancient hunter-gatherers endures.

    DNA from the 7,700-year-old remains of two women is surprisingly similar to that of people living in that area today, researchers report February 1 in Science Advances. That finding suggests that at least some people in...

    CRISPR used in cows to help fight tuberculosis

    Mooooove over CRISPR chickens, pigs and goats. Everyone’s favorite DNA-editing tool is another step closer to transforming the barnyard. 

    Researchers at China’s Northwest Agriculture and Forestry University devised a CRISPR/Cas 9 technique to give cloned dairy cows a leg up against the bacteria behind bovine tuberculosis (Mycobacterium bovis). Last year, another group used TALENs, an...

    CRISPR used in cows to help fight tuberculosis

    Mooooove over CRISPR chickens, pigs and goats. The powerful gene-editing tool is another step closer to transforming the barnyard.

    Researchers at China’s Northwest Agriculture and Forestry University tailored a CRISPR/Cas 9 technique to give cloned dairy cows a leg up against the bacteria behind bovine tuberculosis (Mycobacterium bovis), a threat to cows in many parts of the world. Last...

    Big genetics study blazes path for bringing back tomato flavor

    An analysis of nearly 400 kinds of tomatoes suggests which flavor compounds could bring heirloom deliciousness back to varieties that were bred for toughness over taste.

    About 30 compounds are important in creating a full-bodied tomato flavor, says study coauthor Harry Klee of the University of Florida in Gainesville. He and colleagues have identified 13 important molecules that have...

    Tweaking how plants manage a crisis boosts photosynthesis

    Enhancing just three genes helps plants harvest more light, raising new hopes for developing crops that can keep up with food demands from a crowded planet.

    Genetically engineered tobacco plants, chosen to test the concept, managed the unusual feat of growing 14 to 20 percent more mass — meaning more crop yield — than untweaked plants, says Krishna Niyogi of the University of California...
