Black holes help calibrate gravitational wave detector
Two powerful black hole collisions have allowed scientists to work out how a miscalibrated LIGO detector in Hanford, Washington, was distorting gravitational-wave signals – and use the signals themselves to correct the data.

Cosmic pile-up drives strongest geomagnetic storm in two decades
The strongest geomagnetic storm in two decades was not caused by a single solar eruption. Instead, ten clouds of superheated plasma caught up with one another, merged and compressed, creating a cosmic pile-up that made the storm particularly difficult to predict.

Polish researchers uncover clues to lost Roman temple in Cyprus
Polish researchers working in Cyprus have identified the remains of a monumental structure that may have been a rare Roman-era temple built outside an urban centre. The building, tentatively dated to the late 1st century CE, may have stood on a prominent hill near ancient Kourion, at a junction of routes connecting the region’s cities. Its location and monumental architecture raise the possibility that it was a rural sanctuary, although its exact function remains unknown.

Plant-based diets could strengthen One Health approach, Polish scientists say
Reducing consumption of animal products could lower the risk of chronic diseases and some infections while reducing environmental pressure and the use of antibiotics in farming, according to Polish scientists who argue that diet should play a greater role in the international One Health approach.

Scientists turn thunder into a tool for seeing underground
Sound waves that create thunder during a storm can cause not only window panes to vibrate, but also the ground. A study involving a Polish researcher has shown that the very weak seismic tremors created in this way can be used to image the structure of the subsurface to a depth of 100 metres.

Could life exist in the sulphuric acid clouds of Venus?
New experiments suggest that some of the building blocks of life can survive – and even form complex structures – in concentrated sulphuric acid, raising new possibilities for organic chemistry in the clouds of Venus and on other planets.
