The levitation of microscopic objects in vacuum and the control of their movements while they are suspended was first demonstrated several decades ago. Since then, various research groups have been working on new approaches to control levitated objects in vacuum with greater degrees of freedom. The levitation of microscopic objects in vacuum and the control of…
Using Spektr-RG and Fermi space observatories, German astronomers have investigated the supernova remnant SNR G309.8+00.0 in X-rays and gamma rays. Results of the new study, presented June 25 on the preprint server arXiv, deliver important insights into the properties of this supernova remnant.

In the time it takes you to read this sentence — say, four seconds — the world produces nearly 60 metric tons of plastic, almost entirely out of fossil fuels. That’s about 53,000 metric tons an hour, 1.3 million metric tons a day, or 460 million metric tons a year. Those numbers are fueling widespread…
