Chinese scientists from the Wuhan Institute of Virology said that 15 of the 102 cats studied had detected antibodies to the COVID-19 coronavirus.

102 cats that were taken to shelters or veterinary clinics during the coronavirus epidemic were examined. They took blood samples and smears. There was also a control group of 39 cats treated at clinics in spring 2019. Scientists have evaluated the ability of the body of cats to neutralize the virus.

In 15 cats found a high level of antibodies to coronavirus. In 12 of these antibodies were able to neutralize the virus. Thus, scientists have suggested that about 15% of Welsh cats were infected with a coronavirus. At the same time, there is no confirmation that the coronavirus is transmitted from cats to humans.

3D Tech modeling startup from Lviv has designed a contactless disinfectant design.

They can be handled simply by lifting them to the device and not touching anything. The developers have posted the drawings of the device online, so anyone could print it.

“We wanted to keep hands clean on our 3D farm, but we ran into the problem that there are no cheap, non-contact disinfectants, and expensive ones at $ 4,000 we can’t afford,” says startup founder Paul Joseph about the idea of ​​creating his own disinfectant.

So they decided to design and print their own disinfectant on a 3D printer. The result is a device that handles non-contact, and which can be refilled many times with any liquid solution. The company sells disinfectant at cost (583 UAH, without filler).

Astrophysicists from the University of Durham in England have found that the Milky Way is stretched for 1.9 million light-years.

Professors hope that this data will help them determine the mass of the galaxy in which the solar system is located and the number of galaxies that rotate around it.

To find the end of the Milky Way, astronomers simulated large galaxies on a computer. Scientists estimate that the edge of the Milky Way is about 950 light-years from the center of the galaxy itself.

Google, with the support of the Belgian city of Antwerp, digitizes over 100,000 books published in the 16th-19th centuries.

The Planen-Moretus Museum will provide more than 32,000 books for digitization and the Hendrick Library for more than 60,000 books. All digitized books will be freely available on Google Books and on museum and library sites.

Books will begin digitizing in early 2021. Google expects the whole process to take three years. However, the scanned books will gradually become available.

Flightradar24 has published a message from a pilot from Austria who, on his route, displayed the phrase “Stay home”.

He did this to encourage people to give up traveling because of the spread of the virus. On the Diamond DA40 Diamond Star, the pilot departed Wiener Neustadt and landed in Graz. It took him 24 minutes all the way. You can see how the aircraft prints the letters at this link (https://www.flightradar24.com/data/aircraft/oevds/#24333c62).

A few days later, in the skies above Sydney, Australia, an unknown pilot also “drew” in the sky one of the most important WHO recommendations for the prevention of coronavirus: “Wash your hands.”

NASA engineers have been able to repair an InSight landing gear that crashed while operating on Mars.

The engineers gave him a command to hit himself with a shovel. Scientists have found this the most reliable way. The breakdown occurred when InSight was drilling down Mars to insert a seismometer and examine the internal structure of Mars. Suddenly his drill jammed and even after several attempts to pull the device it remained in place.

It took several months to complete the design, as the impact could have damaged InSight mechanisms, so NASA’s experts first simulated it on Earth. After the impact, the drill bit is released from the adhering soil, and the machine can continue to carry out research.
