Tiny Beams

Physicists have developed the smallest electrically pumped laser ever, with a beam that is 30 micrometers long, eight micrometers high, and has a wavelength of 200 micrometers.

Physicists have developed the smallest electrically pumped laser ever, with a beam that is 30 micrometers long, eight micrometers high, and has a wavelength of 200 micrometers. It is the first time that a laser has been created that is smaller than the wavelength its light emits. Scientists think this product could one day change the way that computer chips are made. "If we manage to approximate the transistors in terms of size using the microlasers, one day they could be used to build electro-optic chips with an extremely high concentration of electronic and optic components," said Christoph Walther, a PhD student in the Quantum Optoelectronics Group at ETH Zurich

Biohacking: Why I'll live to be 180 years old

From computer hacking to biohacking, Dave Asprey has embarked on a quest to reverse the aging process.

Videos
  • As a teenager, founder of Bulletproof, Dave Asprey, began experiencing health issues that typically plague older adults.
  • After surrounding himself with anti-aging researchers and scientists, he discovered the tools of biohacking could dramatically change his life and improve his health.
  • He's now confident he'll live to at least 180 years old. "It turns out that those tools that make older people young make younger people kick ass," he says.

Surprising Science
  • A new report calculated how much electricity Europe could generate if it built onshore wind farms on all of its exploitable land.
  • The results indicated that European onshore wind farms could supply the whole world with electricity from now until 2050.
  • Wind farms come with a few complications, but the researchers noted that their study was meant to highlight the untapped potential of the renewable energy source in Europe.
