Carbon nanotubes with a special coating of reactive fuel can, when ignited, create a thermal wave that not only spreads quickly but also pushes electrons along the tube, creating a substantial electric current. The energy created by MIT engineers far exceeds that predicted by thermoelectric calculations.

I typically attend the annual Pittsburgh Conference on Analytical Chemistry and Applied Spectroscopy each year in pursuit of specific coverage. This year, I sought out candidates for coverage in a vacuum technology article, and pulled together some instruments for a spectroscopy guide. But as busy as that kept me, it wasn’t all mass spectrometers and vacuum pumps on the show floor.

There is no doubt that developing and launching a new product is a challenge. Over the past 47 years, the R&D 100 awards have recognized the 100 most technologically significant new consumer, industrial, medical, and technical products, including multiple technologies (besides accelerator pedals) from Toyota.

Ancient tropical rocks that now reside in the remote northern reaches of Canada tell the tale: about 716.5 million years ago the Earth lay bound in a layer of ice that limited life to eukaryotes. Strangely, this glaciation—history’s most extensive at 5 million years, say researchers at NSF and Harvard—occurred at about the same time that animals appear in the fossil record.
What if space held the key to producing alternative energy crops on Earth? That's what researchers are hoping to find in a new experiment on the International Space Station. The experiment, National Lab Pathfinder-Cells 3, is aimed at learning whether microgravity can help jatropha curcas plant cells grow faster to produce biofuel, or renewable fuel derived from biological matter.
