Worth Doing Right: How Climate Change Could Throw a Wrench Into Road repairs

Repairing with the wrong materials for shifting climates could be a road to nowhere, like this spot in the Suffolk village of Covehithe. Picture by Timothyansell123.

The American Society of Civil Engineers has given America’s roads a D rating. But a recent study shows that trying to raise that grade without accounting for climate change could put the country’s roadways at risk.

Scientific Glassblowing Fuses Art, Science and Innovation

Christine Roeger of the ASU glass shop wears sodium flare eye protection that filters out the orange flame of her torch.

Go to any major research university, and you’ll find the most advanced science relies on an art older than alchemy: glassblowing.

In this piece, we meet a third-generation scientific glassblower and go behind the scenes with some of her chief clients to see how this ancient art helps make cutting-edge research possible.

A Food and Drug Administration ban on over-the-counter antiseptic  soaps and cosmetics containing certain active ingredients goes into effect Sept. 6.  But it’s up to consumers to avoid products the ban doesn’t cover.

Improved imaging of the Earth’s interior has unlocked new subsurface mysteries, including an area 600 miles (1,000 kilometers) down where the mantle’s usual flow pattern changes.

Now, at a lab bench on the planet’s surface, a team of researchers might have found the reason why.

Is Progress Outpacing Precaution? Experts Weigh In

Illustration by An Arres.

No one expects the machinery of progress to roll backwards, but sometimes it seems that no one is watching the speedometer (or manning the brakes, assuming any exist).  Is this a fair assessment? If so, should we be worried — and what can we do about it?

In this feature, experts on technology, risk, science, policy and neuroscience discuss risk, innovation and how our values affect our conceptions of both.
