Richard Mansell, Chief Executive Officer at IVO Limited gave the reasons he is optimistic about the Quantum Space Drive tests that will be done in orbital microgravity.
IF the orbital test works then it will lead to interstellar travel and shrinking it down would give material that would have anti-gravity like effects. We would spend the money to make nanocavities so that we could have propellantless thrust for floating cities. All of space and propulsion related science fiction would become possible within about three decades short of faster than light. This drive is in orbit now for a few months. I think DARPA gave them more money to conclusively prove if it works or not. All of the ground tests show it might work. But if it proves out then we first get 1,000 times better than a hall effect thruster but with no fuel limit. No fuel is used. So long as you have power, solar or nuclear the drive keeps working. So nuclear fuel supply for decades then thrust for decades. The theory proves out, then we make nanocavities which could act like antigravity then we get 1G or even 3G thrusters in space. This would be the Expanse TV show tech.
A team of engineers at the University of Massachusetts Amherst has recently shown that nearly any material can be turned into a device that continuously harvests electricity from humidity in the air.
Researchers describe the “generic Air-gen effect”—nearly any material can be engineered with nanopores to harvest, cost effective, scalable, interruption-free electricity.
In this video, we recount an incident that occurred at OpenAI while researchers were trying to finetune GPT-2 to be as helpful and ethical as possible. It’s narrated that inadvertently flipping a single minus sign led GPT-2 to become the embodiment of a well-known cardinal sin.

Using the valley degree of freedom in analogy to spin to encode qubits could be advantageous as many of the known decoherence mechanisms do not apply. Now long relaxation times are demonstrated for valley qubits in bilayer graphene quantum dots.
A breakthrough discovery of a new superconducting material sets a new record for transition metal sulfide superconductors with a transition temperature of 11.6 K and a high critical current density, marking a significant advancement in superconductor development.
With the support of electrical transport and magnetic measurement systems of Steady High Magnetic Field Facility (SHMFF), a research team from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), discovered a new superconducting material called (InSe2)xNbSe2, which possesses a unique lattice structure. The superconducting transition temperature of this material reaches 11.6 K, making it the transition metal sulfide superconductor with the highest transition temperature under ambient pressure.
The results were published in the Journal of the American Chemical Society.
How human-robot collaboration will affect the manufacturing industry — https://bit.ly/3S7Skfa
By Nitin Rawat, Manufacturing Head, Addverb
Robotics are employed to boost production and efficiency in the manufacturing sector, and they are capable of working in any hazardous setting. Robotic arms are also employed to perform effective work in the industries. It has been years since the introduction of collaborative robots in the manufacturing industry, and they have now been applied in several applications at manufacturing facilities. Robots these days are exceptionally programmable and controllable, allowing them to perform complex tasks using AI and automation.
Robot applications in manufacturing include assembly, welding, shipping, handling raw materials, and product packing. Robots nowadays collaborate with human workers (co-bots) on practically every task. In manufacturing, robotics is used to automate repetitive activities and streamline assembly workflows. Many industries are now using robots for hazardous and time-consuming tasks that can endanger workers.
Spectroscopic data suggest that thin films of a certain semiconducting material can exhibit altermagnetism, a new and fundamental form of magnetism.
By transferring laser-induced graphene to a hydrogel film at cryogenic temperatures, stretchable graphene–hydrogel interfaces can be created for application in wearable and implantable electronics.
