Eggs, long condemned for making raw cookie dough a forbidden pleasure, can stop taking all the blame. There’s another reason to resist the sweet uncooked temptation: flour.
The seemingly innocuous pantry staple can harbor strains of E. coli bacteria that make people sick. And, while not a particularly common source of foodborne illness, flour has been implicated in two E. coli outbreaks...
MINNEAPOLIS — Pesticides that kill insects can also have short-term effects on seed-eating birds. Ingesting even small amounts of imidacloprid, a common neonicotinoid pesticide, can disorient migratory white-crowned sparrows, researchers report.
Neonicotinoid pesticides were designed to be safer than traditional pesticides: toxic to insects, but comparatively harmless to other animals....
Two days before plunging into Saturn, the Cassini spacecraft took one last look around the planet it had orbited for more than 13 years.
The view of Saturn above, released November 21, is actually made from 42 images that have been stitched together. Six moons — Enceladus, Epimetheus, Janus, Mimas, Pandora and Prometheus — are faintly visible as dots surrounding the gas giant (see the...
Science & the Public
Self-driving vehicles passed a major milestone in November when Waymo’s minivans hit the streets of Phoenix without backup human drivers — reportedly making them the first fleet of fully autonomous cars on public roadways. Over the next few months, people will get a chance to take these streetwise vehicles for a free spin as the company tries to drum up excitement — and a customer base — for...
DENVER — An invasive beetle has unexpected — and potentially troublesome — tastes in trees. Now two new studies are clarifying the insects’ dining habits, researchers reported at the annual Entomological Society of America meeting.
Metallic-green Asian beetles called emerald ash borers (Agrilus planipennis) have devastated wide swaths of forest in North America. For years, researchers...
News in Brief
MINNEAPOLIS — Birds don’t need to be drenched in crude oil to be harmed by spills and leaks.
Ingesting even small amounts of oil can interfere with the animals’ normal behavior, researchers reported November 15 at the annual meeting of the Society of Environmental Toxicology and Chemistry North America. Birds can take in these smaller doses by preening slightly greasy feathers or eating...
Around the six-month mark, babies start to get really fun. They’re not walking or talking, but they are probably babbling, grabbing and gumming, and teaching us about their likes and dislikes. I remember this as the time when my girls’ personalities really started making themselves known, which, really, is one of the best parts of raising a kid. After months of staring at those beautiful, bald...

A newly fabricated material does more than just hold up under pressure. Unlike many ordinary objects that shrink when squeezed, the metamaterial — a synthetic structure designed to exhibit properties not typically found in natural materials — expands at higher pressures.
This counterintuitive material is made up of a grid of hollow 3-D crosses — shaped like six-way...

How do you observe the invisible currents of the atmosphere? By studying the swirling, billowing loads of sand, sea salt and smoke that winds carry. A new simulation created by scientists at NASA’s Goddard Space Flight Center in Greenbelt, Md., reveals just how far around the globe such aerosol particles can fly on the wind.
The complex new simulation , powered by...
Much of what happens on the Earth’s surface is connected to activity far below. “Beneath Our Feet,” a temporary exhibit at the Norman B. Leventhal Map Center in the Boston Public Library, explores the ways people have envisioned, explored and exploited what lies underground.
“We’re trying to visualize those places that humans don’t naturally go to,” says associate curator Stephanie Cyr...
