Organic transistors that can simulate basic synaptic functions and act as biomimetic devices are advantageous for next generation bioelectronics. Here, the authors realize non-volatile organic electrochemical transistors with optimized performance required for associative learning circuits.
If a key process for the production of coronavirus proteins is disrupted, viral replication in infected cells can be significantly reduced.

Ninety-three days, 4600 miles, and almost 2 million strokes. That’s what it took Chris Bertish to paddle across the Atlantic Ocean on a stand-up paddle (SUP) board.
“It was pretty radical, pretty incredible, driven by a passion and a purpose greater than yourself—and that powered me to get through everything, day in and day out,” said Bertish in a Skype interview with National Geographic.
Beginning off the coast of Morocco, he travelled for 93 days to reach English Harbour, Antigua, where he arrived haggard and grateful to still be standing.
We visited one of the longest-running cloud seeding operations in the country to get a full demonstration and walk-through of the equipment that aims to increase the rain we get from the clouds passing above our heads.

Israeli/American company Eviation is preparing for the first test flights of its gorgeous Alice, an all-electric 11-seat luxury plane with an impressive 506-mile (814-km) range from a single charge of its huge 820-kWh battery pack.
The company says it’s just taken delivery of its first electric motor, one of three Magnix Electric Propulsion Units the Alice will use to power its three variable pitch pusher props, one on a pod at the end of each wing and a third on the tail. The latter is designed to accelerate fast-moving air around the fuselage and turn the whole body into a bonus wing surface for extra lift.
The prototype is certainly a striking looking aircraft, all space-age looking with its big v-tail and that tastefully squashed high-lift fuselage. Once everything’s all hooked up, it’ll carry two crew and nine passengers at cruise speeds up to 253 mph (407 km/h), and Eviation says the low noise output of its electric powertrain will make a solid contribution to the comfort factor in the back.

A University of California San Diego engineering professor has solved one of the biggest mysteries in geophysics: What causes deep-focus earthquakes?
These mysterious earthquakes originate between 400 and 700 kilometers below the surface of the Earth and have been recorded with magnitudes up to 8.3 on the Richter scale.
Xanthippi Markenscoff, a distinguished professor in the Department of Mechanical and Aerospace Engineering at the UC San Diego Jacobs School of Engineering, is the person who solved this mystery. Her paper “Volume collapse instabilities in deep earthquakes: a shear source nucleated and driven by pressure” appears in the Journal of the Mechanics and Physics of Solids.
The team took the bold step of pointing ESO’s Very Large Telescope, equipped with the MUSE instrument coupled to the telescope’s adaptive optics system, at a single region of the sky for over 140 hours. Together, the two instruments form one of the most powerful systems in the world.[3] The region selected forms part of the Hubble Ultra-Deep Field, which was until now the deepest image of the cosmos ever obtained. However, Hubble has now been surpassed, since 40% of the galaxies discovered by MUSE have no counterpart in the Hubble images.
Universe Today.
Being able to look up at a clear, dark sky is becoming more and more rare in the rich world. Authors, artists, and even scientists have started to express concern about what our lack of daily exposure to a dark night time sky might mean for our psyche and our sense of place in the universe. Now a team has collected photometric data at 44 sites around the world in an attempt to quantify how dark the night sky actually is at different places on the globe. So where was the darkest place surveyed? The Canary Islands.
It just so happens that the lead researcher on the project, Dr. Miguel Alarcón is from that set of islands off the west coast of Africa. The paper he and his colleagues wrote, soon to be published in The Astronomical Journal, used a series of photometers, confusing called TESS (not to be confused with the Transiting Exoplanet Survey Satellite) to try to get a baseline of how dark the night sky is throughout the world.
The team collected 11 million points of data from places as far apart as Namibia, Australia, and the US. While this did not include some more popular astronomy spots, such as the highlands of Antarctica, it was a good sample of different conditions. As mentioned above, the Canary Islands had the lowest levels of background light of anywhere studied. Only about 2% of the light in the sky at night comes from artificial light at the Roque de los Muchachos Observatory in Garafia.
