These are consequential days for ride-sharing companies like Uber and Lyft. Drivers in many U.S. cities are going on strike today, protesting low pay, and analysts expect Uber will likely earn billions when it goes public on Friday. (The two events are not unrelated.)
But amidst the economic discussions, at least we can all agree that it’s good news in terms of traffic, right? The more people rely on professional drivers to get around, the fewer individual cars will be clogging up the str ...read more
In a first, researchers have used chemical fingerprints locked within coral skeletons to build a season-by-season record of El Niño episodes dating back 400 years — a feat many experts regarded as impossible.
That record, presented in a new study appearing in the scientific journal Nature Geoscience, reveals an "extraordinary change" in the behavior of El Niño, according to the researchers. That shift "has serious implications for societies and ecosystems arou ...read more
Coca-Cola has poured millions of dollars into scientific research at universities. But if the beverage giant doesn’t like what scientists find, the company has the power to make sure that their research never sees the light of day.
That’s according to an analysis published in the Journal of Public Health Policy that explains how Coca-Cola uses contract agreements to influence the public health research it financially supports.
The paper explains that Coca-C ...read more

This year, the featured event of #CitSciDay2019 was the StallCatche ...read more
Using nozzle-like extensions on the side of its head, a tropical velvet worm shoots streams of sticky slime when hunting or defending itself.
Within the fluid are “nanoglobules,” tiny balls made of lipids and proteins. Once the slime hits the target, it’s over fast: The movement of the struggling prey, such as beetles and termites, causes the globules to harden into fibers as strong as nylon, creating a netlike trap that immobilizes the unlucky insect.
Remarkably, the ball-to-f ...read more
(Inside Science) -- Science fiction books and films have frequently featured the threat of a giant asteroid colliding with our planet and making humans go the way of the dinosaurs. But smaller space rocks also pose threats, and they tend to be harder to spot in advance.
A massive asteroid on a collision course would sail through our atmosphere and explosively burst in the air or crater the ground. Its invasion would initiate blasts of fire and thermal radiation, and likely cause numerous ...read more
One million species are threatened with extinction, more than ever before in human history, according to a landmark report released Monday from the United Nations. And humanity is responsible.
"Ecosystems, species, wild populations, local varieties and breeds of domesticated plants and animals are shrinking, deteriorating or vanishing," said Josef Settele, an ecologist at the Helmholtz Center for Environmental Research in Germany, who co-chaired the new assessment, in a statement. "Th ...read more
