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

Unraveling the mystery behind dogs' floppy ears

Dogs' floppy ears may be part of why they and other domesticated animals love humans so much.

Surprising Science
  • Nearly all domestic animals share several key traits in addition to friendliness to humans, traits such as floppy ears, a spotted coat, a shorter snout, and so on.
  • Researchers have been puzzled as to why these traits keep showing up in disparate species, even when they aren't being bred for those qualities. This is known as "domestication syndrome."
  • Now, researchers are pointing to a group of a cells called neural crest cells as the key to understanding domestication syndrome.
