Astronomers have discovered two large mysterious objects erupting from the brightest black hole in the known universe. Discovered during a 1959 survey of the cosmos radio wave sources, the supermassive black hole 3C 273 is a quasar – short for “quasi-stellar object”, because the light emitted by these behemoths is bright enough to be mistaken … Read more
Andy Roberts/Getty Images The pop of a champagne cork turns out to have something in common with a rocket launcher, according to a recent paper published in the journal Physics of Fluids. French and Indian scientists have used computer simulations to reveal in detail what happens in the microseconds after a bottle of champagne is … Read more
Credit: ESA / ATG medialab The emergence of a mysterious area in the South Atlantic where the intensity of the geomagnetic field is rapidly decreasing, has led to speculation that the Earth is heading towards a magnetic polarity reversal. However, a new study that collates evidence dating back 9,000 years suggests the current changes are … Read more
We know that virtually all large galaxies, like our own Milky Way, have supermassive black holes at their center. We also strongly suspect that these huge monsters with millions or billions of times the mass of the Sun may have grown from small “seed” black holes called intermediate-mass black holes – or IMBHs – which … Read more

Beads of liquid gallium and platinum close-up. Credit: Dr. Md. Arifur Rahim, UNSW Sydney. Australian researchers have been able to use traces of liquid platinum to create cheap and highly efficient low-temperature chemical reactions, paving the way for dramatic emission reductions in crucial industries. When combined with liquid gallium, the amounts of platinum needed are … Read more
Polar bears and brown bears were still mating long after they split into two separate species, according to a new study. The two species are known to have split between 1.3 and 1.6 million years ago, but new genomic evidence suggests they inherited traits from each other much more recently. Scientists from the United States, … Read more
A next-generation spacesuit has been unveiled by NASA for future ISS and Artemis missions. The suits will be provided by Axiom Space, a private space infrastructure developer, in partnership with Collins Aerospace, an aerospace and defense products supplier. Collins officials said they are opting for a modern, sportier vibe for next-generation spacewear. The cosmonaut suit … Read more
Scientists have used a new tool to discover more than 100 asteroids which had not been previously identified. The method uses a complex computer method called an algorithm to search for asteroids that were undetectable in the past. They were not detectable because existing telescopes and image review tools could not recognize them. Historically, the … Read more
“We haven’t seen any indication of their drinking returning to baseline, so we believe this epigenetic modification may have a lasting effect,” Pandey said. “I think a lot more work needs to be done on how this can be translated into humans for therapy, but I have high hopes.” To test that the Bow gene … Read more
