Microquasars near the Earth emerge as powerful radiation sources
Microquasar V4641 A source of high-energy cosmic rays near Sag. The left side has an energy of over tera electron volts, and the right side has an energy of several hundred tera electron volts. The location of the microquasar is marked with a yellow dot. Credit: IFJ PAN / HAWC Modern astronomy has clung to the idea that relativistic outflows…

Photoswitchable molecules allow writing by radiation or heat and erasing by visible light.
Ultraviolet rays disappear when you write the kanji “light” on treated paper and irradiate it with visible light. Next, marks are made on the treated paper with a soldering iron, and the marks disappear when exposed to visible light. Provided by: Osaka Metropolitan University In the age of cloud storage, few people back up their data to CD-RWs. Technology for…
