Source: Pixabay/CC0 Public Domain For a wide range of industries, separating gases is an important part of both the process and the product. This includes separating nitrogen and oxygen from the air for medical purposes, separating carbon dioxide from other gases in the carbon capture process or removing impurities from natural gas. However, separating gases … Read more
Microtomographic reconstruction of the head and anterior trunk (“body”) limbs of the trilobite Protolenus (Hupeolenus) in ventral view. Credit: Arnaud Mazurier, IC2MP, Univ. Poitiers Researchers have described some of the best-preserved three-dimensional trilobite fossils ever discovered. The fossils, which are more than 500 million years old, were collected in the High Atlas of Morocco and … Read more
Spherical and star-shaped gold nanoparticles (top) and colon cancer cells after approximately five hours of exposure to them (bottom respectively). The photo at the bottom left proves that the cancer cells survived despite the small size of the spherical nanoparticles. False colors.

Ammonites bask in the Late Cretaceous sun. Credit: Artwork by Callum Pursall Scientists have discovered that ammonite species did not decline before their extinction. The coiled-shell marine mollusks, one of paleontology’s greatest icons, thrived in Earth’s oceans for more than 350 million years until they became extinct during the same accidental event that wiped out … Read more

This image of NASA’s Perseverance rover collecting data on the wear of the “Valhalla Glades” was taken June 14 in the “Bright Angel” area of ​​Jezero Crater by one of the rover’s forward hazard avoidance cameras. The WATSON camera on the SHERLOC instrument is closest to the surface of Mars. Credit: NASA/JPL-Caltech After six months … Read more
Shocked quartz grains, with cracks filled with molten glass. Credit: UC Santa Barbara Researchers continue to build the case for the Younger Dryas Impact hypothesis. The idea holds that a fragmented comet slammed into Earth’s atmosphere 12,800 years ago, triggering widespread climate change that led to, among other things, an abrupt reversal of Earth’s warming … Read more
Inspired by LEGO, ESA scientists have used dust from a meteorite to 3D print LEGO-style ‘space bricks’ to test out building ideas for a future moon base. Credit: The LEGO Group ESA scientists have investigated how a future moon base could be built from materials on the moon’s surface. Inspired by building with LEGO, they … Read more
