Avi Schiffmann has been procrastinating on his school work, but he has a good excuse. The 17-year-old high schooler is the creator of one of the most visited coronavirus trackers in the world, which he says now takes up “100 percent” of his free time.

The coronavirus pandemic doesn’t look like it will be over any time soon, and Schiffmann plans to continue actively tracking it until the end. As long as the site is up, he says he will keep working at it and adding new features. Once the pandemic is safely over, he’ll take the servers down, and maybe make a page that compares COVID-19 to SARS or the Spanish flu. He thinks it might be a historical piece on the coronavirus people can look back on.

Avi Schiffmann’s coronavirus tracker is a one-stop shop for all the information about COVID-19 the average person might want to know. It constantly updates with statistics for countries around the world on infections, deaths, recovered, and rates of change using data scraped from the WHO, CDC, and other government websites.

Shoes will invariably wear out with enough use, but scientists might have found a way to delay the shopping trip for their replacements. A USC team has created a self-healing 3D-printed rubber that could be ideal for footwear, tires and even soft robotics. The effort involves 3D printing the material with photopolymerization (solidifying a resin with light) while introducing an oxidizer at just the right ratio to add self-healing properties without slowing down the solidifying process.

Quantum entanglement – that strange but potentially hugely useful quantum phenomenon where two particles are inextricably linked across space and time – could play a major role in future radar technology.

In 2008, an engineer from MIT devised a way to use the features of entanglement to illuminate objects while using barely any photons. In certain scenarios, such technology promises to outperform conventional radar, according to its makers, particularly in noisy thermal environments.

Now, researchers have taken the idea much further, demonstrating its potential with a working prototype.

That strategy was unveiled in a directive on Wednesday by the Ministry of Industry and Information Technology (MIIT), which called on local authorities in 23 provinces, five autonomous regions and four municipalities to support the establishment of these new big data centres, which will help bolster efforts to upgrade the country’s manufacturing sector.

The Ministry of Industry and Information Technology has called on local authorities in 23 provinces, five autonomous regions and four municipalities to support the establishment of new ‘industrial big data’ centres, which would bolster the digital transformation of various industries.

Over the past several years, the increased application of unmanned air vehicles (UAVs) in a wide variety of industries has inspired both public and private research laboratories to not only continually improve this technology, but to also support the miniaturization of these devices. The development of both micro- and nano-UAVs is directly related to the ability of researchers to miniaturize the major components of these devices, some of which include micro-processors, sensors, batteries and all necessary wireless communication units that allow UAVs to function properly in any given settings.

With the help of the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory, Juliette Stecenko is exploring cosmology—a branch of astronomy that investigates the origin and evolution of the universe, from the Big Bang to today and into the future. As an intern through DOE’s Science Undergraduate Laboratory Internships (SULI) program, administered at Brookhaven by the Office of Educational Programs (OEP), Stecenko is using modern supercomputers and quantum computing platforms to perform astronomy simulations that may help us better understand where we came from.

Stecenko works under the guidance of Michael McGuigan, a computational scientist in the quantum computing group at Brookhaven’s Computational Science Initiative. The two have been collaborating on simulating Casimir energy—a small force that two electrically neutral surfaces held a tiny distance apart will experience from quantum, atomic, or subatomic fluctuations in the vacuum of space. The vacuum energy of the universe and the Casimir pressure of this energy could be a possible explanation of the origin and evolution of the universe, as well a possible cause of its accelerated expansion.

“Casimir energy is something scientists can measure in the laboratory and is especially important for nanoscience, or in cosmology, in the very early universe when the universe was very small,” McGuigan said.
