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

Green and gold bell frogs in artificial hotspot shelter. Credit: Anthony Waddle Researchers from Macquarie University have used heat to develop a simple and effective way to help endangered frogs survive the devastating effects of a multi-species pandemic. In collaboration with the University of Melbourne, researchers have delved into the fungal disease chytridiomycosis, which has … Read more
Hackers can siphon data from a Neuralink computer chip embedded in a person’s brain, the first patient to receive the advanced medical device had admitted. Noland Arbaugh, the 29-year-old patient who was left paralyzed below the shoulder after a diving accident, discussed the threat of hackers in a candid podcast interview with Joe Rogan. Asked … Read more
Credit: AI-generated image A physicist who studies black holes has discovered that in an expanding universe, Einstein’s equations require that the rate of expansion of the universe at the event horizon of each black hole must be constant, and the same for all black holes. This in turn means that the only energy on the … Read more
Researchers from Tel Aviv University have successfully manufactured a new type of glass that, while retaining its transparency, is able to immediately merge with the touch of water at room temperature. The research was published in the peer-reviewed scientific journal Nature. The research, led by PhD student Gal Finkelstein-Zuta and Prof. Ehud Gazit of … Read more
