There's already plenty of angst out there about the prospect of jobs lost to artificial intelligence, but this week, artists got a fresh reason to be concerned. A new "Rembrandt" painting unveiled in Amsterdam is not the work of the Dutch master Rembrandt van Rijn at all, but rather the creation of a combination of technologies including facial recognition, AI, and 3D printing. Essentially, a deep-learning algorithm was trained on Rembrandt's 346 known paintings and then asked to produce a brand-new one replicating the artist's subject matter and style. Dubbed "The Next Rembrandt," the result is a portrait of a caucasian male, and it looks uncannily like the real thing. One particularly interesting detail about The Next Rembrandt project, which was a collaboration among several organizations including Dutch bank ING and Microsoft, is how the algorithm chose the subject for its painting, since it had to be entirely new.

The Japanese automaker already has a research lab in the Silicon Valley technology hub of Palo Alto, where it works with Stanford University, and another in Cambridge, Massachusetts, where it collaborates with MIT. Its new facility near the University of Michigan will have a staff of about 50 employees. The world's top-selling automaker announced in November that it would invest 1 billion in research and development over the next five years in artificial intelligence technologies, which are critical to the computer brains of self-driving cars. Toyota's investment in R&D comes as competition in the fast-moving field of autonomous vehicles expands beyond carmakers in Asia, Europe and the United States to non-traditional sources such as Alphabet's Google and Apple. The new Ann Arbor facility will focus primarily on fully autonomous driving, in which the car takes full control, the company said.

Last week I hired a personal assistant named Amy Ingram. She set up four meetings for me, adding them to my calendar with the relevant contact details included. She rescheduled twice when the person I was supposed to meet had to cancel at the last minute. Instead of sending half a dozen emails per meeting, I only needed to compose one to kick things off. This all sounds like pretty simple stuff, but Amy isn't a human being: it's a virtual assistant made by the New York City startup X.ai.

Today is christening day for DARPA's Sea Hunter, a full-scale prototype of an autonomous surface vessel that's designed to be able to launch from a pier and go out on its own for weeks or months at a time, for thousands of miles at a stretch. The 132-foot-long, diesel-powered vessel was built by U.S. defense contractor Leidos under DARPA's ACTUV program, a somewhat clunky nested acronym that stands for Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel. The ship, now a joint project with the U.S. Office of Naval Research, was originally conceived as a tracker of stealthy diesel-electric submarines, but it's a flexible platform. "What we've kind of realized over the course of the program is that it's a truck," program manager Scott Littlefield tells IEEE Spectrum. "It's got lots of payload capacity for a variety of different missions."

Years from now, a robotic astronaut named Val could walk across the dusty Martian terrain to greet a spaceship carrying humans ready to colonize the Red Planet. How well the robot does that job will fall to some Bay State universities, who are playing a key role in teaching Val how to be an astronaut's best friend. "What she will be able to do, hopefully, is just about everything that a suited astronaut in a planetary field could do," said Kris Ver deyen, NASA project manager for Val. "This is NASA's first foray into a bipedal motion robot, so we're basically learning the ropes as we go." Val -- short for Valkyrie -- is a 6-foot, 2-inch, 300-pound mass of metal, wires and plastic that was delivered to University of Massachusetts Lowell at 6:30 yesterday morning, along with a squad of NASA engineers, who put together the robot piece by piece.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

This week in Amsterdam, a team of computer scientists and Rembrandt experts unveiled a new portrait that looks alarmingly similar to the work of the famed Dutch artist. The portrait of a man wearing a broad hat is the latest example of how advanced computer methods are making it increasingly easy to mimic the style of history's most acclaimed artists. Art that hangs in museums, sells for millions and that has endured for generations is being emulated by computer wizards without the pedigree of Rembrandt and kin. When lined up against Rembrandt's work, it can be difficult to tell which portrait a machine created and which the Dutch painter created roughly 400 years ago. The creators of the "new Rembrandt" used computers to 3D scan and analyze 346 Rembrandt paintings.

It is almost an impossible choice - deciding whether to sacrifice the life of one innocent person to save the lives of five others. But scientists have discovered that the choice you make in this scenario could have a drastic impact on how trustworthy people think you are. The findings may help to explain why humans are often drawn to moral choices that do not benefit the greater good, such as refusing to make such sacrifices. Psychologists have explored why humans seen to be drawn to making'illogical' moral choices, like sacrificing the lives of many to save the life of one person, depicted in Saving Private Ryan (pictured). It suggests there may be certain rules about morality hardwired into human nature due to our evolution as a social species. Jim Everett, a psychologist at the University of Oxford who led the work, said such rule-based decisions - known as deontological morality which focuses on ideas of right and wrong – may have served to increase group cohesion in the past by helping people trust each other.

Once, a messenger app did just that – message. But with the rise of artificial intelligence, tech companies are falling over themselves to prove how much more useful and interactive their apps can be – which is why you're about to see an explosion of "bots". Kik, the mobile chat application popular with teenagers, launched its Bot Shop on 5 April, and Facebook is poised to launch its own bot store for Facebook Messenger next week. Every brand from Barbie to the Washington Post seems to be working on a chat bot of its own. For Kik, chat bots are the next step in the evolution of the internet.
