China claims new world record for strongest steady magnetic field

The new world record of 45.22 tesla steady state high magnetic field. Credit: SHMFF team On August 12, the hybrid magnet of the Steady High Magnetic Field Facility (SHMFF) in Hefei, China, produced a steady field of 45.22 tesla (T), the highest steady magnetic field by a working magnet in the world. It broke the …

Revealing the salty secrets of the biggest environmental shift since dinosaurs

Credit: Unsplash/CC0 Public Domain A new Nature Geoscience study from The Australian National University (ANU) offers further clues about what happened to the Mediterranean during a tumultuous period that likely included the most catastrophic flooding event in Earth’s recorded history. The Zanclean megaflood happened around 5 million years ago following the collapse of the Gibraltar …

X-ray marks the spot in elemental analysis of 15th-century printing press methods

A photograph of a scanned Korean text. The white dotted box indicates the areas shown in the middle and bottom panels. Each element produces a unique X-ray fluorescence. After scanning the text, the researchers applied filters for the known XRF patterns of different elements and created a color-coded heat-map of their abundance, from lowest (blue) …

A simple way of sculpting matter into complex shapes

In the attached image, light which twists shines on a moving BEC, breaking it into clusters of BEC droplets that move following the light’s features. Credit: University of Strathclyde A new method for shaping matter into complex shapes, with the use of ‘twisted’ light, has been demonstrated in research at the University of Strathclyde. When …

Matter at extreme conditions of very high temperature and pressure turns out to be remarkably simple and universal

Credit: Pixabay/CC0 Public Domain Scientists at Queen Mary University of London have made two discoveries about the behavior of “supercritical matter”—matter at the critical point where the differences between liquids and gases seem to disappear. While the behavior of matter at reasonably low temperature and pressure was well understood, the picture of matter at high …

Nuclear fusion: Ignition confirmed in an experiment for the first time

A 2021 experiment achieved the landmark milestone of nuclear fusion ignition, which data analysis has now confirmed – but attempts to recreate it over the last year haven’t been able to reach ignition again Physics 11 August 2022 By Karmela Padavic-Callaghan The National Ignition Facility at Lawrence Livermore National Laboratory We have ignition. An analysis …
