A single biohybrid robotic finger at work. The contracting and expanding muscles are those pink things at the top of the device

Incredible results from telescope aimed at black hole — Our own galaxy’s black hole is called Sagittarius A* and is four million times the mass of the Sun. The EHT scientists analysed 2013 data, which included the first southern hemisphere telescope added to the EHT’s network. Even using just this old data, scientists are getting really close to seeing the black hole. These are not the results of the impressive 2017 observations but even still, the scientists detected hints of structures near the black hole, at a distance three times the radius of the black hole’s event horizon.
~ I wonder what a black hole will look like … if only the name was more descriptive!

Hololens as a visual prosthesis — New research shows that Microsoft’s HoloLens augmented-reality headset works well as a visual prosthesis for the vision impaired, not relaying actual visual data but guiding them in real time with audio cues and instructions. TechCrunch reports:
The researchers, from Caltech and University of Southern California, first argue that restoring vision is at present simply not a realistic goal, but that replacing the perception portion of vision isn’t necessary to replicate the practical portion. After all, if you can tell where a chair is, you don’t need to see it to avoid it.
~ But will it help you sit down in it? 

Microsoft and Apple collaborated to make a new braille standard — The non-profit USB Implementers Forum (USB-IF) has announced a new standard for braille displays. It was developed in cooperation with Microsoft, Apple and other tech industry leaders. The USB Human Interface Device (HID) standard will make it easier for blind or low vision users to use braille displays across operating systems and hardware. It will also remove the need for specialised or custom drivers and simplify development.
~ Good feelings. 

Robotics combined with living cells — By growing muscles on an artificial skeleton, researchers from Japan have constructed an agile and surprisingly durable ‘biohybrid’ robotic finger joint. The breakthrough could eventually lead to more life-like robots and advanced prostheses.
~ Weird feelings.

Ancient coastal route to to America — The first people to cross into North America from Eurasia did so by travelling through the Bering Strait, or so the theory goes. A new theory has emerged proposing a coastal route into the continent, but evidence has been lacking. A recent analysis of boulders, bedrock, and fossils in Alaska is now providing a clearer picture, pointing to the emergence of a coastal route some 17,000 years ago. Archaeological evidence places humans in Chile around 15,000 years ago, and in Florida some 14,500 years ago yet the retreating ice sheets didn’t yield an interior pathway until about 14,000 years ago.
~ In Home Sapiens history – around 200,000–300,000 years – that’s still relatively recent. 

Ice Age Americas meet-up — As the last Ice Age was coming to an end, and as the first settlers arrived in North America, two distinct populations emerged. One of these groups would eventually go on to settle South America, but as new genetic evidence shows, these two ancestral groups – after being separated for thousands of years – had an unexpected reunion. The finding is changing our conceptions of how the southern continent was colonised and by whom.
~ But nothing prepared them for the Spanish.
