One Form of Online Shopping Is Better for the Climate (It’s Not Amazon)

Photo: GettyI use dry red lentils, black peppercorns, and capers a lot. And now, I’m out.

Flat Earth advocate dies after homemade rocket crashes

Earlier this year, Starbucks said it was committed to a "resource-positive future," which includes expanding plant-based options and creating a more environmentally friendly menu.

After Math: Anything worth doing is worth overdoing

Did the Curiosity rover need to dutifully snap 1,200 images of the rugged Martian landscape?

Lettuce grown on the ISS is as nutritious as Earth harvests, scientists find

The main difference between the two is that the ISS vegetables have more microorganisms, but that's probably just because of the microflora that live on the space station. None of them, however, are harmful to humans, such as E. coli and Salmonella. The scientists' findings are significant, because they tell us that we can grow…

Scientists develop neuroprosthetic tech that amputees don’t need to learn

One of the biggest challenges in mind-controlled prosthetics is finding a strong and stable enough nerve signal to attach to the bionic limb. Scientists already know that peripheral nerves – the network of tiny nerves that fan out to the spinal cord and brain -- are liable to offer the most precise and intuitive control…
