Tech News Review Week 15-22 February 2021, by Stelios Iordanis



Scientists establish freaky two-way communications with lucid dreamers

This can establish two-way communications with people in the bizzare, hallucinatory state of lucid dreaming, making real-time “interactive dreaming” research possible.

Until now, only fragmented, fading scraps of memory people had once they’ve woken up were accessible, of course.


New plant-based plastics can be chemically recycled with near-perfect efficiency – The Academic Times

They can be recycled with a recovery rate of more than 96%, as low-waste, environmentally friendly replacements to conventional fossil fuel-based plastics.


A new approach for brain-controlled wheelchairs could achieve 99% driving accuracy – The Academic Times

For the first time, it is possible to achieve a highly reliable and nearly 100% accurate brain–computer interface system for use in brain-controlled wheelchairs, without imposing a high mental workload on the user acting as a direct communication pathway between a wired brain and an external device giving commands through brain signals without muscle activity.


New technology enables predictive design of engineered human cells

A design-driven process that uses parts from a very different kind of toolkit to build complex genetic circuits for cellular engineering that can lead to more sophisticated functions and make therapies safer and more effective.



Quantum computing

Toward the first quantum simulation with quantum speedup | PNAS

The proposed circuits are orders of magnitude smaller than those for the simplest classically infeasible instances of factoring and quantum chemistry, bringing practical quantum computation closer to reality.


Quantum Holograms Could Make Ridiculously Detailed Images of Our Bodies And Cells

holograms that decipher biological mechanisms in tissues and living cells are thus feasible that cam analyse red blood cells to detect the presence of malaria parasites and identify sperm cells for IVF processes, for instance.


New Physics Rules Tested by Using a Quantum Computer to Create a “Toy-Universe”

Several novel optical or microwave-based devices developed in recent times do seem to operate according to such phenomena and this research has synergies insimulating these devices on quantum computers.


Machine Learning

AI: IBM showcases new energy-efficient chip to power deep learning | ZDNet

This is the first AI accelerator chip that is built on high-performance seven-nanometer technology, while also reaching high levels of energy efficiency.



Military Engineering

US Army Testing Machine Gun-Style Laser Weapon That Vaporizes Targets


The new weapon, by contrast, is powerful enough to vaporize rather than melt metal, making it a far more effective armament while also acting as an electromagnetic pulse (EMP) and disrupting nearby electronics, and all this could befeasible with tech that already exists today.


Fighter Pilots Blacked Out From Gs, Got Saved by AI Co-Pilot

The system takes the speed, altitude, and flight paths of the aircraft into account before taking over flight control deciding if the jet is going to crash into the ground and corrects the flight path to avoid catastrophe.



U.S. Navy controls inventions that claim to change “fabric of reality” – Big Think

U.S. Navy holds patents for exotic borderline sci-fi inventions by aerospace engineer Dr. Salvatore Pais that can “engineer” reality, devising an ultrafast craft, a fusion reactor, and other incredible technological feats.

While mostly theoretical at this point, these inventions could transform energy, space, and military sectors and we cannot be sure to which degree they may have already been developed by the US Army already.




Scientists Invent Artificial Muscle That Gets Stronger With Exercise

These artificial muscles grow stronger — 66 times stronger, in fact — via an analogous orocess. A gel is embedded with nanomaterials that link together and build strong new bonds when the gel is compressed or mechanically stressed, ideal for robot’s muscles.
