Hot-blooded T. rex and cold-blooded Stegosaurus: Chemical clues reveal dinosaur metabolisms Posted: 25 May 2022 08:08 AM PDT There's a new method for determining whether dinosaurs were hot- or cold-blooded, using clues in their bones that indicated how much the individual animals breathed in their last hour of life. The study shows that the bird-hipped dinosaurs like T. rex and Brachiosaurus were hot-blooded, while the lizard-hipped dinosaurs like Triceratops and Stegosaurus were cold-blooded. |
New discovery about distant galaxies: Stars are more massive than we thought Posted: 25 May 2022 07:29 AM PDT A team of astrophysicists has arrived at a major result regarding star populations beyond the Milky Way. The result could change our understanding of a wide range of astronomical phenomena, including the formation of black holes, supernovae and why galaxies die. |
Wake up and smell the burning rubbish? Secrets of disordered smell found Posted: 25 May 2022 07:29 AM PDT Researchers have discovered the secrets of why certain food and drinks smell (and likely taste) disgusting to people with parosmia. |
Hubble reaches new milestone in mystery of universe's expansion rate Posted: 24 May 2022 01:00 PM PDT NASA's Hubble Space Telescope has calibrated more than 40 'milepost markers' of space and time to help scientists precisely measure the expansion rate of the universe -- a quest with a plot twist. |
Breakthrough in quantum universal gate sets: A high-fidelity iToffoli gate Posted: 24 May 2022 09:49 AM PDT Researchers have demonstrated the first three-qubit high-fidelity iToffoli native gate in a superconducting quantum information processor and in a single step. This demonstration adds a novel easy-to-implement native three-qubit logic gate for universal quantum computing. |
Traveling wave of light sparks simple liquid crystal microposts to perform complex dance Posted: 24 May 2022 09:48 AM PDT Mastering control over the dynamic interplay among optical, chemical and mechanical behavior in single-material, liquid crystalline elastomers, results in microposts that combine bending, twisting and turning into complex dances. The advancement could contribute toward further development of soft robotics and other devices. |
