This concept could lead to a new energy source for deep-space exploration missions based on nuclear fusion in the space between the atoms of a metal solid. It also could be used on Earth for electrical power or creating medical isotopes for nuclear medicine.

 

Researchers develop ‘acoustic metamaterial’ that cancels sound

https://phys.org/news/2019-03-acoustic-metamaterial-cancels.html

the acoustic metamaterial could potentially be scaled “to fit inside the central bore of an MRI machine,” shielding patients from the sound during the imaging process. Moreover, the noise mitigation method can be customized to suit nearly any environment by mathematically designing an object that can block the sounds of anything,

 

Electronics

Future iPhones could use laser detection of poisonous gas, air quality, or pollen | AppleInsider

https://appleinsider.com/articles/20/09/29/future-iphones-could-use-laser-detection-of-poisonous-gas-air-quality-or-pollen

Future mobile devices will warn users about poisonous gas or pollen in the local environment, sensing the air using a combination of lasers and other sensors.

 

Apple patents hydrogen fuel cells for MacBooks and iPads | TechRadar

https://www.techradar.com/news/apple-patent-hydrogen-fuel-cell-macbook-ipad

The underlying patent uses “proton exchange membrane (PEM) fuel cells” that convert hydrogen into electricity and power a computer for “days or even weeks without refueling”.

AI System Tops One Billion Neurons on a Desktop Computer – Novus Light Today

https://www.novuslight.com/artificial-intelligence-system-tops-one-billion-neurons-on-a-desktop-computer_N10773.html

One billion neurons on a desktop computer comprised completely of off-the-shelf components. processed three billion synapses per second.

This machine exceeds the processing performance of the human neocortex as CPU alone contains nearly 40 billion transistors and each transistor is nearly a billion times faster than each of the neocortex’s 16 billion neurons.

Chemistry

Plastic-eating enzyme ‘cocktail’ heralds new hope for plastic waste — ScienceDaily

https://www.sciencedaily.com/releases/2020/09/200928152913.htm

The scientists have created an enzyme ‘cocktail’ which can digest plastic up to six times faster.

A second enzyme, found in the same rubbish dwelling bacterium that lives on a diet of plastic bottles, has been combined with PETase to speed up the breakdown of plastic.

 

A new way to automate sequences of chemical reactions

https://phys.org/news/2020-10-automate-sequences-chemical-reactions.html

This breakthrough automates sequences of chemical reactions via a new spinning device that performs multiple reactions and separations which could ultimately lead to cheaper pharmaceutical substances, that require a complex synthesis process.

 

Energy

Untapped potential exists for blending hydropower, floating PV

https://techxplore.com/news/2020-09-untapped-potential-blending-hydropower-pv.html

Adding floating solar panels to bodies of water that are already home to hydropower stations could produce as much as 7.6 terawatts of potential power a year from the solar PV systems alone, or about 10,600-terawatt-hours of potential annual generation. Those figures do not include the amount generated from hydropower.

 

Quantum Computing

D-Wave announces launch of new Advantage quantum computer for business use

https://phys.org/news/2020-09-d-wave-advantage-quantum-business.html

D-Wave has developed a new quantum computer for use by businesses with 5,000 qubits available over the Internet aiming at practical mathematical optimization problems from all industrials sectors, e.g. for designing new proteins, grocery chain business operations, or car painting systems optimization.
