Some physicists claim the popular landscape of universes in string theory may not exist.

Machine learning is everywhere these days, but it’s usually more or less invisible: it sits in the background, optimizing audio or picking out faces in images. But this new system is not only visible, but physical: it performs AI-type analysis not by crunching numbers, but by bending light. It’s weird and unique, but counter-intuitively, it’s an excellent demonstration of how deceptively simple these “artificial intelligence” systems are.
Machine learning systems, which we frequently refer to as a form of artificial intelligence, at their heart are just a series of calculations made on a set of data, each building on the last or feeding back into a loop. The calculations themselves aren’t particularly complex — though they aren’t the kind of math you’d want to do with a pen and paper. Ultimately all that simple math produces a probability that the data going in is a match for various patterns it has “learned” to recognize.
The thing is, though, that once these “layers” have been “trained” and the math finalized, in many ways it’s performing the same calculations over and over again. Usually that just means it can be optimized and won’t take up that much space or CPU power. But researchers from UCLA show that it can literally be solidified, the layers themselves actual 3D-printed layers of transparent material, imprinted with complex diffraction patterns that do to light going through them what the math would have done to numbers.

The year is 2050 and researchers have developed an advanced method of replacing 99% of your brain’s functions for digital software/hardware. The process is slow to ensure individuals aren’t simply making copies of themselves. But in return, “digital immortality” has been achieved.
In a future of mind-uploaded “immortals,” will we achieve unlimited freedom or will we simply become slaves to a private entity which owns the data that makes up our own digital minds?

Published in Scientific Reports, this study is the first to provide evidence of new neuron formation—and the presence of stem cells—in the leopard gecko brain.
University of Guelph researchers have discovered the type of stem cell allowing geckos to create new brain cells, providing evidence that the lizards may also be able to regenerate parts of the brain after injury.
This finding could help in replacing human brain cells lost or damaged due to injury, aging or disease.
“The brain is a complex organ and there are so few good treatments for brain injury, so this is a very exciting area of research,” said Prof. Matthew Vickaryous in the Department of Biomedical Sciences at the Ontario Veterinary College (OVC).
A very nice summary on everyone in the new space race.
Just a few months ago, SpaceX’s Falcon Heavy created History by not only sending a car to Outer Space but also landing the Boosters with Pin point accuracy. It may seem that the Future of Space Race will be dominated by SpaceX, or is it?
In this video we look into the Competitors of SpaceX, some of whom have great plans to take on SpaceX, by launching reusable rockets like Jeff Bezos’s Blue origin or by simple efficient and low cost manufacturing process as implemented by India, whose low cost seems to have baffled even the experts.
