No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.

As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?

It’s a monumental head-scratcher known as the ‘grandfather paradox’, but in September last year a physics student Germain Tobar, from the University of Queensland in Australia, said he has worked out how to “square the numbers” to make time travel viable without the paradoxes.

A tiny implant offers a new weight loss option, and a gastric bypass alternative, for people suffering from obesity.

The device uses light to stimulate the nerve responsible for regulating food intake. A tiny glow from the implant and users don’t feel as hungry — instead, they feel full.

Researchers at Texas A&M say that this dime-sized device could provide a far less invasive surgical option than the so-called stomach stapling surgery — which is currently a last resort surgery for obese patients. This could be a viable option for a gastric bypass alternative.

Automation ‘to keep people safe’

Hong Kong-based Hanson Robotics said four models, including Sophia will start to be mass produced in the first half of 2021.

This coincides with a rise in automation documented worldwide as robotics technologies are used to allow everyday tasks to be carried out amidst social distancing restrictions.… See More.

About the size of toenail clippings, planarians are freshwater flatworms that can re-form from tiny slivers. This feature not only lets them repair themselves, but it lets them reproduce by breaking apart and then creating new worms.

HOUSTON — (Jan. 252021) — Wireless communication directly between brains is one step closer to reality thanks to $8 million in Department of Defense follow-up funding for Rice University neuroengineers.

The Defense Advanced Research Projects Agency (DARPA), which funded the team’s proof-of-principle research toward a wireless brain link in 2018, has asked for a preclinical demonstration of the technology that could set the stage for human tests as early as 2022.

“We started this in a very exploratory phase,” said Rice’s Jacob Robinson, lead investigator on the MOANA Project, which ultimately hopes to create a dual-function, wireless headset capable of both “reading” and “writing” brain activity to help restore lost sensory function, all without the need for surgery.
