Researchers from the University of Cambridge used a numerical experiment to determine the limits of matt structural color – a phenomenon which is responsible for some of the most intense colors in nature – and found that it extends only as far as blue and green in the visible spectrum. The results, published in PNAS, could be useful in the development of non-toxic paints or coatings with intense color that never fades.

 

Structural color, which is seen in some bird feathers, butterfly wings or insects, is not caused by pigments or dyes, but internal structure alone. The appearance of the color, whether matt or iridescent, will depending on how the structures are arranged at the nanoscale.

Measurements of trace gases in planetary atmospheres help us explore chemical conditions different to those on Earth. Our nearest neighbor planet, Venus, has clouds that are temperate but hyperacidic. Here we report the apparent presence of phosphine (PH3) gas in Venus’s atmosphere, where any phosphorus should be in oxidized forms. Single-line millimeter-waveband spectral detections (quality up to ~15σ) from the JCMT and ALMA telescopes have no other plausible identification.

(CNN)A Japanese company has announced the successful test drive of a flying car.

Sky Drive Inc. conducted the public demonstration on August 25, the company said in a news release, at the Toyota Test Field, one of the largest in Japan and home to the car company’s development base. It was the first public demonstration for a flying car in Japanese history.
The car, named SD-03, manned with a pilot, took off and circled the field for about four minutes.
"We are extremely excited to have achieved Japan’s first-ever manned flight of a flying car in the two years since we founded SkyDrive… with the goal of commercializing such aircraft," CEO Tomohiro Fukuzawa said in a statement.

A chemical you’ve likely never heard of has burst into the news thanks to scientists’ announcement that they have detected phosphine, which they say may be a sign of life, in the clouds of Venus.

Here’s everything you need to know about phosphine, the strange chemical detected in the atmosphere of Venus.

Using a new machine-learning algorithm, MIT researchers have identified a powerful antibiotic that can kill a wide range of species of pathogenic bacteria, including some that are resistant to all known antibiotics.

 

The computer model, which can screen more than a hundred million chemical compounds in a matter of days, is designed to pick out potential antibiotics that kill bacteria using different mechanisms than those of existing drugs. "We wanted to develop a platform that would allow us to harness the power of artificial intelligence to usher in a new age of antibiotic drug discovery," says James Collins, the Termeer Professor of Medical Engineering and Science in MIT’s Institute for Medical Engineering and Science (IMES) and Department of Biological Engineering. "Our approach revealed this amazing molecule which is arguably one of the more powerful antibiotics that has been discovered."

By detecting subtle differences in the way that Alzheimer’s sufferers use language, researchers at Stevens Institute of Technology have developed an A.I. algorithm that promises to accurately diagnose Alzheimer’s without the need for expensive scans or in-person testing. The software not only can diagnose Alzheimer’s, at negligible cost, with more than 95 percent accuracy, but is also capable of explaining its conclusions, allowing physicians to double check the accuracy of its diagnosis.

Artificial skin reacts to pain just like real skin, opening the way to better prosthetics, smarter robotics and less invasive options for skin grafts.

 

Researchers have developed electronic artificial skin that reacts to pain just like real skin, opening the way to better prosthetics, smarter robotics and non-invasive alternatives to skin grafts. The prototype device developed by a team at RMIT University in Melbourne, Australia, can electronically replicate the way human skin senses pain. The device mimics the body’s near-instant feedback response and can react to painful sensations with the same lighting speed that nerve signals travel to the brain.

In ten years artificially intelligent robots will be living and working with us, according to Dr. Mark Sagar, CEO of Soul Machines, an Auckland, New Zealand-based company that develops intelligent, emotionally responsive avatars.

 

Sagar, an AI engineer, is the inventor of a virtual nervous system that powers autonomous animated avatars like Baby X — a virtual infant that learns through experience and can “feel” emotions.

 

“We are creating realistic adult avatars serving as virtual assistants. You can use them to plug into existing systems like IBM Watson or Cortana — putting a face on a chatbot,” said Sagar.

Within a decade humans will be interacting with lifelike emotionally-responsive AI robots, very similar to the premise of the the HBO hit series Westworld, said Sagar.

 

But before that scenario becomes a reality robotics will have to catch up to AI technology. “Robotics technology is not really at the level of control that’s required,” he said.

Elon Musk demonstrated a working Neuralink brain-machine interface device implanted on a pig during a live broadcast.  He said the purpose of the presentation was to recruit employees that would like to help develop the system. – “We’re not trying to raise money or do anything else, but the main purpose is to convince great people to come work at Neuralink, and help us bring the product to fruition; make it affordable and reliable and such that anyone who wants one can have one,” he said. Neuralink aims to solve brain-related issues with the brain chip called ‘Link’. Musk said the device could help solve memory loss, strokes, addiction, depression, anxiety, even monitor a users’ health to warn if they are about to have a heart attack. The interface could also help return mobility to paralyzed individuals through artificial limbs. The user would be able to move prosthetics with their thoughts via the Link brain-machine interface.
