Dynamical fermionization involves velocity, as well as position.

On Tuesday, the first version of Dragon completed its 20th and final mission.

Tesla will cut pay for all of its salaried employees and will furlough hourly workers until May 4, when it intends to resume production of electric cars, according to an internal e-mail that multiple employees shared with CNBC. The pay reductions are expected to be in place until the end of the second quarter.

Health orders, implemented to curb the spread of COVID-19, forced Elon Musk’s electric car company to wind down production at its main vehicle assembly plant in Fremont, California.

The new pay cuts follow Tesla’s first-quarter vehicle production and deliveries report, which pleased investors — the company said it delivered approximately 88,400 vehicles and produced 103,000 in Q1. Tesla has yet to withdraw guidance it gave investors for 2020, saying it should “comfortably exceed” 500,000 vehicle deliveries for the year.

Researchers lifted the ancient Egyptian mummy out of her coffin for the first time in 100 years and, to their surprise, uncovered the ancient artworks.

New research shows that resveratrol, a chemical found in red wine, contributes to genomic stability by reducing the occurrence of DNA double-strand breaks and prolongs lifespan in genetically modified mice that are prone to carcinogenic mutations [1].

DSBs and genomic instability

Genomic instability, one of the hallmarks of aging, is a condition characterized by frequent mutations within the genome, and it has long been associated with cancer [2]. The authors of this study state that one of its major causes is the erroneous repair of DNA double-strand breaks (DSBs). High numbers of DSBs have been found in pre-cancerous cells, and DNA lesions caused by unrepairable DSBs accumulate with time, both in organisms and in cultured cells. One of the possible culprits is the degradation of DNA repair mechanisms in aged cells [3].

Utilizing the antibodies from the plasma of survivors of the coronavirus to help those who are critically ill from the coronavirus has been deemed successful:

The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers.

A heads up: Dyson has “created 44 engineering and science activities for children to try out while at home during the coronavirus pandemic, from making a balloon-powered car to building a bridge from spaghetti,” writes the Dezeen website. They go on to add: “Comprised of 22 science tasks and 22 engineering activities, the Challenge Cards can be completed by children using common household items such as eggs, string and balloons.” You can also find a related playlist of videos on YouTube, one of which appears above.

This engineering/science activities have been added to our refreshed collection, 200 Free Kids Educational Resources: Video Lessons, Apps, Books, Websites & More. If you know of any great K-12 resources, especially ones that are always free, please add them in the comments below, and we will try to add them to the list.
