Smallest Doppler Found!

Chrisharvey/Dreamstime.com

Scientists have detected the Doppler effect on the scale of a single molecule. The Doppler effect (or Doppler shift), named after Austrian physicist Christian Doppler who proposed it in 1842 in Prague, is the change in frequency of a wave for an observer moving relative to the source of the wave. It is commonly heard when a vehicle sounding a siren or horn approaches, passes, and recedes from an observer. The received frequency is higher (compared to the emitted frequency) during the approach, it is identical at the instant of passing by, and it is lower during the recession.

6 Ways Mushrooms Can Save The World

Entrepreneurial mycologist Paul Stamets seeks to rescue the study of mushrooms from forest gourmets and psychedelic warlords. The focus of Stamets’ research is the Northwest’s native fungal genome, mycelium, but along the way he has filed 22 patents for mushroom-related technologies, including pesticidal fungi that trick insects into eating them, and mushrooms that can break down the neurotoxins used in nerve gas.
There are cosmic implications as well. Stamets believes we could terraform other worlds in our galaxy by sowing a mix of fungal spores and other seeds to create an ecological footprint on a new planet.

“Once you’ve heard ‘renaissance mycologist’ Paul Stamets talk about mushrooms, you’ll never look at the world — not to mention your backyard — in the same way again.”
