With North Korean leader Kim Jong-un pulling back out his nuclear card for the first time since 2018, a very natural and perhaps even urgent question is, what next? There are signs that the North is getting closer to unveiling its strategic weapon promised by Kim at the end of last year. But with the U.S. constrained and South Korea committed to global sanctions, there’s no sign of a dialogue breakthrough. We could be about to witness Pyongyang’s new way.

If a drop of creamer falls from a spoon into a swirling cup of coffee, the whirlpool drags the drop into rotation. But what would happen if the coffee had no friction—no way to pull the drop into a synchronized spin?
Circa 2015
Physicists have created a wormhole device that can tunnel a magnetic field through space. It sounds like Star Trek, but we won’t be zapping humans across the universe anytime soon. Still, the breakthrough could revolutionize certain magnet-based technologies, including MRIs.
The existence of a planet the size of Earth around the closest star to the Sun, Proxima Centauri, has been confirmed by an international team of scientists including researchers from the University of Geneva (UNIGE). The results, published in Astronomy & Astrophysics, reveal that the planet in question, Proxima b, has a mass of 1.17 Earth masses and is located in the habitable zone of its star, which it orbits in 11.2 days.
This breakthrough was possible thanks to radial velocity measurements of unprecedented precision using ESPRESSO, the Swiss-manufactured spectrograph, the most accurate currently in operation, which is installed on the Very Large Telescope in Chile. Proxima b was first detected four years ago by means of an older spectrograph, HARPS, also developed by the Geneva-based team, which measured a low disturbance in the star’s speed, suggesting the presence of a companion.
The ESPRESSO spectrograph has performed radial velocity measurements on the star Proxima Centauri, which is only 4.2 light-years from the sun, with an accuracy of 30 centimetres a second (cm/s), about three times more precision than that obtained with HARPS, the same type of instrument but from the previous generation.

“Pavegen creates high engagement with citizens by converting their footsteps into energy, data and rewards.
As pedestrians walk across the Pavegen system, the weight from their footsteps compresses electromagnetic generators below, producing 2 to 4 watt seconds of off-grid electrical energy per step.”

A team at Harvard has identified molecules that restore protective caps on the tips of our chromosomes that regulate cells ageing.
Israeli entrepreneurs and researchers have introduced facemask and face shield inventions we want to tell you about.
Let’s begin with an update on that first article highlighting washable masks from Sonovia and from Argaman. Each uses its own proprietary technology to embed microbe-killing metallic particles into textiles.

Paris (AFP) — An antibody from a patient who recovered from SARS has been shown to block COVID-19 infection in a laboratory setting, researchers said Monday in another potential breakthrough in the search for coronavirus treatment.
Scientists based in Switzerland and the United States previously isolated the antibodies from the patient in 2003, following the SARS outbreak that killed 774 people.
They experimented with 25 different types of antibodies — which target specific protein spikes on viruses — to see if they could prevent cells becoming infected with COVID-19.
