From the spread of coronavirus to International Women's Day, these 10 images sum up all the big stories from the previous week.

Here's a presentation of some of the best photos from around the world in the month gone by.

A few days ago, Martín Borthiry contacted me with a question. He had been using the optimized asynchronous Google Analytics snippet for a while, and noticed an additional speed gain when wrapping it inside a setTimeout() with a delay of 0 milliseconds. His tests made it pretty clear that this technique was indeed slightly faster, but Martín had no clue why.

Collecting back-scattered X-rays from vacuum windows using a pinhole X-ray camera provides an efficient and reliable method of measuring the beam shape and position of the white synchrotron beam. In this paper, measurements are presented that were conducted at ESRF beamline ID6 which uses an in-vacuum cryogenically cooled permanent-magnet undulator (CPMU18) and a traditional U32 undulator as its radiation sources, allowing tests to be performed at very high power density levels that were adjusted by changing the gap of the undulators. These measurements show that it is possible to record beam shape and beam position using a simple geometry without having to place any further items in the beam path. With this simple test setup it was possible to record the beam position with a root-mean-square noise figure of 150 nm.
