For centuries, humankind has been captivated by the thought of life on other planets. But how will we recognise it when we see it? Researchers have developed an artificial intelligence system that can detect signs of life with 90 per cent accuracy. And they say it signifies a'significant advance' in our abilities to discover life across the solar system and beyond. Many of the components necessary for life, such as amino acids and nucleotides needed to make DNA, have been detected in space.

Thomas Fuchs, the Dean of Artificial Intelligence and Human Health at Mount Sinai in NYC, said AI will be needed to retain the standard of care in the U.S. Artificial intelligence (AI) is helping physicians to diagnose cancer more accurately at much faster rates and at a lower cost than previously possible, according to a scientist working in computational pathology. Dr. Thomas J. Fuchs, the Dean of Artificial Intelligence and Human Health at Mount Sinai in New York City, also works as the chief scientific officer at Paige AI, a company using AI to detect and treat cancer. The latest study from the company tasked 16 pathologists with the review of 610 whole-slide images prepared at multiple institutions globally. They reviewed the slides once without assistance, and then again with assistance from the Pathology Artificial Intelligence Guidance Engine (Paige AI). When Paige AI was used, diagnostic errors reduced by 70%.

The stunning detail of the Martian landscape was taken on a ridge of elevation 327 metres (1,073 feet). The image looks over the Gale Crater which is about 3.5-3.8 billion years old and covers an area 96 miles (154 kilometres) in diameter - about the same size as Rhode Island and Connecticut combined Nasa's Jet Propulsion Laboratory (JPL) in Pasadena, California, released the panorama, which gives an overview of much of the rover's 11 mile (18 km) path along the crater's outer edge. The photos were taken on October 25, 2017, by Curiosity's Mast Camera, or Mastcam. At an elevation of 327 metres (1,073 feet), the image looks over the crater, which is about 3.5-3.8 billion years old and covers an area 96 miles (154 kilometres) in diameter - about the same size as Rhode Island and Connecticut combined. Most of the scene's horizon is the crater's northern rim, roughly around 1.2 miles (two kilometres) above the rover.

What is it like to drive on Mars? Every movement on the rough terrain risks damage to the wheels on NASA's Curiosity rover, which would be stranded on the alien planet, a trip of several months away from any Earth help, should anything go seriously wrong. To avoid a terminal error, NASA has developed a new algorithm for driving its rover that changes the wheels' speed based on what rocks are beneath them. NASA's Jet Propulsion Laboratory said the software was uploaded onto the rover earlier this year, following months of testing on the ground, and the space agency started using it in June. It's geared toward traction control -- stopping the six wheels from spinning at different speeds when one or more of them climbs over a rock.
