NASA Wants Green Jets

They might be best known for space travel, but the folks at NASA are determined to shape the future of commercial aviation. The agency says airliners need to be greener.

NASA’s goal is to develop technology that would enable future aircraft to burn 50% less fuel than current models, cut harmful emissions in half and shrink the geographic areas affected by obnoxious airport noise by 83%. The agency hopes to develop concepts for airliners that could go into service by 2025. Engineers from Lockheed’s famed-Skunkworks defense enclave in Palmdale won about $3 million to develop the concept. Northrop engineers, working out of the company’s space park in El Segundo, were given $2.65 million. The engineers will have 12 months to develop a concept for an aircraft that can fly near the speed of sound at a range of 7,000 miles, carrying up to 100,000 pounds of either passengers or cargo.

Why is 18 the age of adulthood if the brain can take 30 years to mature?

Neuroscience research suggests it might be time to rethink our ideas about when exactly a child becomes an adult.

Mind & Brain
  • Research suggests that most human brains take about 25 years to develop, though these rates can vary among men and women, and among individuals.
  • Although the human brain matures in size during adolescence, important developments within the prefrontal cortex and other regions still take pace well into one's 20s.
  • The findings raise complex ethical questions about the way our criminal justice systems punishes criminals in their late teens and early 20s.

Apparently even NASA is wrong about which planet is closest to Earth

Three scientists publish a paper proving that Mercury, not Venus, is the closest planet to Earth.

Strange Maps
  • Earth is the third planet from the Sun, so our closest neighbor must be planet two or four, right?
  • Wrong! Neither Venus nor Mars is the right answer.
  • Three scientists ran the numbers. In this YouTube video, one of them explains why our nearest neighbor is... Mercury!

Mini-brains attach to spinal cord and twitch muscles

A new method of growing mini-brains produces some startling results.

(Lancaster, et al)
Surprising Science
  • Researchers find a new and inexpensive way to keep organoids growing for a year.
  • Axons from the study's organoids attached themselves to embryonic mouse spinal cord cells.
  • The mini-brains took control of muscles connected to the spinal cords.
