    Hurricane Willa breaks an eastern and central Pacific storm season record

    From Hawaii to Mexico, powerful storms have buffeted a wide swath of the Pacific Ocean in 2018. Now, with Hurricane Willa bearing down on southwestern Mexico on October 23, the hurricane season across the central and eastern regions of the Pacific has become the most active on record — at least by one measure, known as accumulated cyclone energy.

    So far in 2018, there have been 22 named...

    Saturn’s moon Dione has stripes like no others in the solar system

    Saturn’s moon Dione is streaked with long bright stripes, and no one knows how they got there.

    Planetary scientists first noticed the stripes in pictures taken with NASA’s Cassini spacecraft, which orbited Saturn from 2004 to 2017 (SN: 4/14/18, p. 6). Found near the moon’s equator, the long, thin, bright lines run surprisingly parallel to each other for tens to hundreds of kilometers....

    This cloud-zapping laser could help scientists create a quantum internet

    On an overcast day, ultrafast lasers could clear a path through the clouds, allowing easier contact with satellites traveling high above Earth.

    Currently, cloudy weather limits scientists’ ability to send data to satellites via lasers, because the clouds scatter the lasers’ light. But a powerful, fast-pulsing laser can zap a tiny, cloud-free channel, allowing a second laser to slip...

    Teens use Juul e-cigarettes much more often than other vaping products

    Teens who try the latest, sleekest iteration of electronic cigarettes may be more likely to become regular users, compared with those who try other e-cigarettes or regular cigarettes, a new study suggests.

    These pod-mod e-cigarettes, which resemble a USB drive, come with a prefilled pod of flavored liquid that contains a higher concentration of nicotine than other e-cigarettes. And the...

    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...

    T. rex pulverized bones with an incredible amount of force

    ALBUQUERQUE — Tyrannosaurus rex had a special way of crunching bones.

    A lethal combination of a powerful bite, strong teeth and repeated crunching allowed these giant predators to pulverize the bones of their prey, researchers reported October 20 at the Society for Vertebrate Paleontology’s annual meeting.

    Bones have a nutritious inner cavity containing marrow and phosphate salts....

    An eye disorder may have given Leonardo da Vinci an artistic edge

    If Leonardo da Vinci had a good eye doctor, he might not have become such a great artist. At least that’s what an analysis of paintings and sculptures believed to be modeled after da Vinci suggests.

    Visual neuroscientist Christopher Tyler of the City University of London examined six pieces of art, including Salvator Mundi and Vitruvian Man. Five of the pieces depict an eye misalignment...

    How to make organ transplants last

    Trent Jackson’s life changed abruptly in early 2015. The computer engineer thought he had the flu. His then-wife, Donna Sylvia, thought differently. His skin was turning a dark golden yellow, almost brown, “like he was getting some kind of weird tan,” she says. On Wednesday, January 28, Sylvia and Jackson’s brother Todd finally persuaded Jackson to see a doctor.

    Sylvia’s suspicions were...

    DNA differences are linked to having same-sex sexual partners

    SAN DIEGO — For some people, choosing a same-sex partner may be in their DNA.

    In a large study of more than 490,000 men and women in the United States, United Kingdom and Sweden, researchers discovered four genetic variants that occur more often in people who indicated on questionnaires that they had had same-sex sexual partners. Andrea Ganna, a geneticist at the Broad Institute of MIT...

    New therapies pack a triple-drug punch to treat cystic fibrosis

    For years, scientists have struggled to find a therapy that works for most cystic fibrosis sufferers. Now, two new triple-drug approaches, still undergoing testing, are offering hope.

    Cystic fibrosis is caused by mutations in a gene called CFTR. These mutations mean the body either makes defective versions of a protein, also called CFTR, or none of the protein at all. The new therapies...
