Shaped like a splayed starfish with five legs, the stargate lies on the surface of a virus and remains sealed during much of its life cycle. But once inside a host cell, each leg of the stargate "unzips", allowing viral genetic material to slip through the resulting hole, said senior author Kristin Parent, an associate professor of Biochemistry and Molecular Biology at Michigan State University. The new study, published May 8 in the journal Cell, demonstrates that the stargate opens in response to acidic, salty and high-temperature environmental conditions. … [Read more...] about Giant viruses spew their DNA through a ‘stargate.’ Now, scientists know what triggers them.

Some bat species prefer to live in colonies, close to one another, creating a perfect setting for pathogens to spread between each other — and to other species who might also share the space. Bats are also the only mammals capable of true flight, making it easier for them to spread diseases through their guano (bat feces). … [Read more...] about Why bats don’t get sick from the viruses they carry, but humans can
Then you pop the sensor up somewhere -- Airthings recommend having it at breathing height, although you can place it on a shelf or even mount to the wall of ceiling using the supplied mount -- and then let if start monitoring. Some sensors start working right away, but other sensors such as the radon sensors take seven days to properly calibrate. … [Read more...] about Airthings Wave Plus: Indoor air quality monitor that also warns you if you’re breathing in deadly radon gas
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
Repeated absorption and re-emission of photons by atoms or molecules in the gain medium gives rise to quasiparticles called polaritons. In certain conditions — before the energy level required for conventional lasing is reached — the polaritons synchronize into a joint quantum state called a condensate, which gives off laser light. … [Read more...] about New Laser Created from Jellyfish’s Fluorescent Proteins
