    A Bronze Age tomb in Israel reveals the earliest known use of vanilla

    DENVER — Three jugs placed as offerings in a roughly 3,600-year-old tomb in Israel have revealed a sweet surprise — evidence of the oldest known use of vanilla.

    Until now, vanilla was thought to have originated in Mexico, perhaps 1,000 years ago or more. But jugs from the Bronze Age site of Megiddo contain remnants of two major chemical compounds in natural vanilla extract, vanillin and...

    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...

    Small doses of peanut protein can turn allergies around

    Carefully calibrated doses of peanut protein can turn extreme allergies around. At the end of a year of slowly increasing exposure, most children who started off severely allergic could eat the equivalent of two peanuts.

    That reversal, reported November 18 in the New England Journal of Medicine, “will be considered life-transforming for many families with a peanut allergy,” says...

    In an attempt to curtail an alarming rise in teenage vaping, the U.S. Food and Drug Administration announced restrictions on the sale of certain flavored e-cigarettes that appeal to young people on November 15. The agency also said it would seek to ban menthol cigarettes, long a goal of public health advocates, as well as flavored cigars.

    The flavor restrictions coincide with the release...

    Lyme and other tickborne diseases are on the rise in the U.S. Here’s what that means.

    There’s no sign that ticks are backing down.

    A record high of 59,349 cases of tickborne diseases were reported in 2017 in the United States. That’s a 22 percent increase in cases — or roughly 11,000 more — than were reported in 2016, the Centers for Disease Control and Prevention announced on November 14.

    Lyme disease accounted for most of the reported diseases, with nearly 43,000...

    Coffee or tea? Your preference may be written in your DNA

    Whether people prefer coffee or tea may boil down to a matter of taste genetics.

    People with a version of a gene that increases sensitivity to the bitter flavor of caffeine tend to be coffee drinkers, researchers report online November 15 in Scientific Reports. Tea drinkers tended to be less sensitive to caffeine’s bitter taste, but have versions of genes that increase sensitivity to the...

    Sound-absorbent wings and fur help some moths evade bats

    Some moths aren’t so easy for bats to detect.

    The cabbage tree emperor moth has wings with tiny scales that absorb sound waves sent out by bats searching for food. That absorption reduces the echoes that bounce back to bats, allowing Bunaea alcinoe to avoid being so noticeable to the nocturnal predators, researchers report online November 12 in the Proceedings of the National Academy of...

    How mammoths competed with other animals and lost

    The Gray Fossil Site, a sinkhole in northeastern Tennessee, is full of prehistoric treasures. Between 7 million and 4.5 million years ago, rhinoceroses, saber-toothed cats and other creatures, even red pandas, perished here by the edge of a pond. But that bounty of fossils pales next to the site’s biggest find: a mastodon’s skeleton, nearly 5 million years old, preserved in exquisite detail...

    A potent fish oil drug may protect high-risk patients against heart attacks

    Cholesterol-lowering drugs may one day gain a sidekick in the battle against heart disease. Taking a potent drug derived from fish oil along with a statin lowers the risk of heart attack and stroke in some high-risk people, researchers report.

    A clinical trial called REDUCE-IT tested the approach in more than 8,000 participants who either had cardiovascular disease or were at high risk...

    How a life-threatening allergic reaction can happen so fast

    Within minutes of biting into peanut-tainted food, people with a peanut allergy may find their pulse quickening, blood pressure plummeting and throat closing up. They’re experiencing a rapid and sometimes fatal allergic reaction called anaphylaxis.

    New research in mice explains how even a small amount of an allergen can quickly trigger such a strong, full-body reaction. The culprit is a...
