Rolls-Royce is building robot roaches and snakes to repair airplane engines

Posted by in categories: robotics/AI, transportation

The engines of an airplane are complicated machines with plenty of hard-to-reach places, and keeping them in working order requires a lot of time and maintenance. The future of this task, as Rolls-Royce sees it, could involve deploying different kinds of of robots that patrol these aircraft parts and quickly nip any problems in the bud.

Researchers develop new solar sailing technology for NASA

Posted by in categories: materials, space travel

Spacecraft outfitted with sails and propelled by the sun are no longer the stuff of science fiction or theoretical space missions. Now, a Rochester Institute of Technology researcher is taking solar sailing to the next level with advanced photonic materials.

Metamaterials—a new class of manmade structures with unconventional properties—could represent the next technological leap forward for solar sails, according to Grover Swartzlander, professor in RIT’s Chester F. Carlson Center for Imaging Science. He proposes replacing reflective metallic sails with diffractive metafilm sails. The new materials could be used to steer reflected or transmitted photons for near-Earth, interplanetary and interstellar space travel.

“Diffractive films may also be designed to replace heavy and failure-prone mechanical systems with lighter electro-optic controls having no moving parts,” he said.

No more zigzags: Scientists uncover mechanism that stabilizes fusion plasmas

Posted by in categories: nuclear energy, physics

Sawtooth swings—up-and-down ripples found in everything from stock prices on Wall Street to ocean waves—occur periodically in the temperature and density of the plasma that fuels fusion reactions in doughnut-shaped facilities called tokamaks. These swings can sometimes combine with other instabilities in the plasma to produce a perfect storm that halts the reactions. However, some plasmas are free of sawtooth gyrations thanks to a mechanism that has long puzzled physicists.

Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) have recently produced complex simulations of the process that may show the physics behind this , which is called “ pumping.” Unraveling the process could advance the development of fusion energy.

Scientists have created an AI inside a test tube using strands of DNA, and they hope it will soon start to form its own ‘memories’

Posted by in categories: biotech/medical, robotics/AI

An artificial neural network that’s made entirely from DNA and mimics the way the brain works has been created by scientists in the lab.

The test tube artificial intelligence can solve a classic machine learning problem by correctly identifying handwritten numbers.

CRISPR editing may cause more DNA damage than expected

Posted by in categories: biotech/medical, genetics

“The DNA chaos that CRISPR unleashes has been ‘seriously underestimated,’” study author and geneticist Allan Bradley of U.K.’s Wellcome Sanger Center tells STAT. “This should be a wake-up call.”

Scientists just found £150,000,000,000,000,000,000,000,000 of diamonds on Earth

Posted by in category: economics

Don’t tell the Hatton Garden gang: scientists just unearthed an eye-watering hoard of diamonds, so valuable it would completely destroy the world’s economy.

The scientists reckon there’s a quadrillion tonnes of diamond buried in the ‘cratonic roots’ in continents.

There’s just one, tiny, catch: the treasure trove is buried 100 miles down, deeper than any drill has ever penetrated, according to MIT researchers.
