Second exoplanet detected orbiting an early G-type star
Astronomers report the detection of a second exoplanet orbiting a G-type star known as TIC 393818343, located some 300 light years away. The newfound alien world is about three times less massive than Jupiter. The finding ...
Cats associate human words with images, experiment suggests
A small team of animal scientists at Azabu University, in Japan, has found via experimentation that common house cats are capable of associating human words with images without prompting or reward. In their study, published ...
Physicists report emergence of ferromagnetism at onset of Kondo breakdown in moiré bilayer lattices
Moiré superlattices are materials consisting of two layers stacked on top of each other with either a small rotational misalignment or a lattice mismatch between them. The Kondo lattice model, on the other hand, describes ...
Using gamma-ray bursts to probe origin of star formation excess discovered by Webb
Among its other notable achievements and puzzles, the James Webb Space Telescope (JWST) has found a larger number of bright galaxies in the distant universe than was expected. While scientists are still debating the excess, ...
Explosive pollen wars: Plants fight for pollen-space on pollinators
Scientists from South Africa and Brazil have provided empirical evidence that pollen grains of rival plants may compete with one another for space on pollinators, thus influencing whose pollen is going to make it to the next ...
