Researchers from Kazan Federal University, Texas A&M University and Institute of Applied Physics (Russian Academy of Sciences) found ways to direct high frequency gamma radiation by means of acoustics.
Their paper describes an optical ‘switch’—a device able to let through or stop gamma quanta by switching the acoustic field. Basically, the mechanism makes iron ‘transparent’ for gamma rays when needed.
The Mossbauer Spectroscopy Lab of Kazan Federal University showed acoustically induced transparency of a resonant medium for gamma radiation in an experiment. The essence of this phenomenon lies in the transformation of the spectrum of the absorption line into a comb structure consisting of satellite lines spaced from the main line by the frequency of the acoustic field. For the experiment, gamma quanta with an energy of 14.4 keV were used, which are emitted during the decay of the excited state of the iron-57 nucleus.
Synairgen, a drug company founded by professors from the University of Southampton, UK, has announced promising results from its clinical trial of SNG001 – an inhaled formulation of interferon beta, in hospitalised COVID-19 patients.

A video on Youtube claims a forecast of near-Earth objects (NEOs) shows one of these may hit Earth in November.
On November 2, 2020 an object labeled 2018 VP1″ is currently projected to come very close to Earth. The video is a little off on its math. Even so, Mike Murray of the Delta College Planetarium in Bay City, says don’t worry.
Mars in 4 K.
A world first. New footage from Mars rendered in stunning 4K resolution. We also talk about the cameras on board the Martian rovers and how we made the video.
The cameras on board the rovers were the height of technology when the respective missions launched.

Data storage technology continues to shrink in size and grow in capacity, but scientists have just taken things to the next level — they’ve built a nanoscale hard drive using a single atom.
By magnetising an atom, cooling it with liquid helium, and storing it in an extreme vacuum, the team managed to store a single bit of data (either a 1 or a 0) in this incredibly miniscule space.
