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 …

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) …

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 …

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 …

Evidence that giant meteorite impacts created the continents

Credit: Pixabay/CC0 Public Domain New Curtin research has provided the strongest evidence yet that Earth’s continents were formed by giant meteorite impacts that were particularly prevalent during the first billion years or so of our planet’s four-and-a-half-billion year history. Dr. Tim Johnson, from Curtin’s School of Earth and Planetary Sciences, said the idea that the …

Physics connects seismic data to properties of rocks and sediments

Credit: NASA/JPL-Caltech A new analysis of seismic data from NASA’s Mars InSight mission has revealed a couple of surprises. The first surprise: the top 300 meters of the subsurface beneath the landing site near the Martian equator contains little or no ice. “We find that Mars’ crust is weak and porous. The sediments are not …
