Flying cars are being developed by companies spanning from new startups like Ehang and Pal-V, to industry giants like Airbus and Rolls-Royce.

 

Not long ago, the idea of traveling by flying car was pure science fiction. The Jetsons made the concept famous, but turning such a machine into reality seemed like a step too far. How should they be governed? Would you need a license? Where would they land and take-off from?

Blood Falls is an aptly named feature in Antarctica. The 100-foot stream of water running down the side of a glacier is a deep, rich, blood red.

 

Though we’ve known for decades what causes the red color, it took more than 100 years for scientists to discover the source of Blood Falls: a secret, ancient, underground lake.

 

Blood Falls were first discovered by Australian explorer Griffith Taylor during an expedition in 1911. At the time, he and other explorers guessed that the red color might be caused by algae living in the water.

Observations made with ESO’s Very Large Telescope have for the first time revealed the effects predicted by Einstein’s general relativity on the motion of a star passing through the extreme gravitational field near the supermassive black hole in the centre of the Milky Way. This long-sought result represents the climax of a 26-year-long observation campaign using ESO’s telescopes in Chile.

The expression of a gene involved in female birds’ color vision is linked to the evolution of colorful plumage in males, reports a new study from the University of Chicago. The findings, published Nov. 26 in the Proceedings of the Royal Society B, confirm the essential role of female color perception in mate selection and sexual dimorphism.

 

"This is the first time an aspect of the visual system in birds has been directly associated with plumage evolution," said Natasha Bloch, PhD, who authored the study while a graduate student in ecology & evolution at the University of Chicago. "It tells us color perception plays an important role in the evolution of the spectacular diversity of colors we see in nature."

Professor Ishikawa Komuro’s Tokyo lab is better known for robot hands that can dribble and catch balls and spin pencils between their fingers. Now, two researchers have taken this speedy sensing tech and applied it to the ripping of paper books.

 

Books are different from other kinds of media, like music and movies – it’s very hard to get them into a computer. There is no equivalent of CD or DVD rippers like iTunes or Handbrake. This not only makes piracy laborious, it also stops you from turning your own books into e-books.

 

This high-speed scanner changes that, at least if you have the room and tech skills to build one. By using a high-speed camera that shoots at 500 frames per second, lab workers Takashi Nakashima and Yoshihiro Watanabe can scan a 200-page book in under a minute. You just hold the book under the camera and flip through the pages as if shuffling a deck of cards. The camera records the images and uses processing power to turn the odd-shaped pictures into flat, rectangular pages on which regular OCR (optical character recognition) can be performed.

 

The technique is unlikely to be coming to the home anytime soon (although ripping a book by flipping it in front of your notebook’s webcam would be pretty awesome), but it could certainly speed up large scanning efforts like Google’s book project.
