The 20-sided viruses included in the study represent just one class of giant virus, but the same research methods could be used to study many other species, "with genomes and particles never described before," Abrahão said. Giant viruses contain genes and proteins that "do not resemble anything in the cellular world," or even other viruses, Abergel added. Future studies could reveal when and how these viruses first evolved, and why they differ so drastically from more familiar forms of life. … [Read more...] about Giant viruses spew their DNA through a ‘stargate.’ Now, scientists know what triggers them.

The other reasons are grounded in evidence. Bats are the second-most species-rich order of mammals. There are more than 1,400 species distributed worldwide, except in Antarctica. They live in urban and natural areas, and they all have the potential to carry viruses. Bats are also mammals, and this relatedness to humans makes them more likely to be hosts of zoonoses than birds and reptiles, for example. … [Read more...] about Why bats don’t get sick from the viruses they carry, but humans can
Technology giants — including Amazon, Facebook, Hewlett Packard Enterprise (HPE), IBM, Microsoft, and Sandia National Laboratories — have announced that they are making all of their patents freely available to the public for use in the fight against Covid-19. The companies are doing this as part off joining the ‘Open Covid Pledge,’ which is a coalition of scientists and technologists to make their intellectual property available free of charge for use in ending the COVID-19 pandemic and minimising the impact of the disease. “Microsoft is always looking for ways to use our patents to contribute to positive outcomes, and the fight against Covid-19 is one of the most urgent issues of our time,” said Jennifer Yokoyama, chief IP Counsel of Microsoft. “Pledges and open licensing like this effort can help spur innovation, especially in a crisis like this one. Researchers, scientists, and others working against the virus should be able to develop and … [Read more...] about Amazon, IBM, Microsoft to make patents available for free to fight Covid-19
Traditional polariton lasers using inorganic semiconductors need to be cooled to incredibly low temperatures. More recent designs based on organic electronics materials, like those used in organic light-emitting diode (OLED) displays, operate at room temperature but need to be powered by picosecond (one-trillionth of a second) pulses of light.

"There are laser beams where the intense piece propagates on a curved trajectory," Clerici told Live Science. Such a beam is called an Airy beam, after the mathematician George Biddel Airy, who described why rainbows look curved. The lens that makes the Airy beam is shaped to do that to a laser — make the focused region of the beam into a curved shape. "It's essentially a badly designed lens," Clerici said. … [Read more...] about ‘Iron Man’ Laser: Beams Can Shape Electrical Discharges
