| Beacon from the early universe Posted: 01 Jul 2020 01:01 PM PDT Often described as cosmic lighthouses, quasars are luminous beacons that can be observed at the outskirts of the Universe, providing a rich topic of study for astronomers and cosmologists. Now scientists have announced the discovery of the second-most distant quasar ever found, at more than 13 billion lightyears from Earth. |
| Higher concentration of metal in Moon's craters provides new insights to its origin Posted: 01 Jul 2020 12:17 PM PDT Life on Earth would likely not be possible without the Moon; it keeps our planet's axis of rotation stable, which controls seasons and regulates our climate. However, there has been considerable debate over how the Moon was formed. The popular hypothesis contends that the Moon was formed by a Mars-sized body colliding with Earth's upper crust which is poor in metals. But new research suggests the Moon's subsurface is more metal-rich than previously thought, providing new insights that could challenge our understanding of that process. |
| Jellyfish-inspired soft robots can outswim their natural counterparts Posted: 01 Jul 2020 12:17 PM PDT Engineering researchers have developed soft robots inspired by jellyfish that can outswim their real-life counterparts. More practically, the new jellyfish-bots highlight a technique that uses pre-stressed polymers to make soft robots more powerful. |
| Different tracks, same dinosaurs: Researchers dig deeper into dinosaur movements Posted: 01 Jul 2020 09:55 AM PDT Using X-ray-based technology, researchers uncover shared subsurface movement patterns between birds and dinosaurs, adding a new dimension of fossil track diversity. |
| Coordinating complex behaviors between hundreds of robots Posted: 01 Jul 2020 09:54 AM PDT Researchers propose a new approach to finding an optimal solution for controlling large numbers of robots collaboratively completing a set of complex linear temporal logic commands called STyLuS*, for large-Scale optimal Temporal Logic Synthesis, that can solve problems massively larger than what current algorithms can handle, with hundreds of robots, tens of thousands of rooms and highly complex tasks, in a small fraction of the time. |
| First exposed planetary core discovered allows glimpse inside other worlds Posted: 01 Jul 2020 09:54 AM PDT The surviving core of a gas giant has been discovered orbiting a distant star, offering an unprecedented glimpse into the interior of a planet. |
| A binary star as a cosmic particle accelerator Posted: 01 Jul 2020 07:01 AM PDT Scientists have identified the binary star Eta Carinae as a new kind of source for very high-energy (VHE) cosmic gamma-radiation. Eta Carinae is located 7500 lightyears away in the constellation Carina in the Southern Sky and, based on the data collected, emits gamma rays with energies up to 400 gigaelectronvolts (GeV), some 100 billion times more than the energy of visible light. |
| Posted: 01 Jul 2020 07:00 AM PDT Scientists create a theoretical carbon-based material that would be even harder than diamond. This work may have industrial applications for cutting and polishing in place of current synthetic diamond. |
| Tabletop quantum experiment could detect gravitational waves Posted: 01 Jul 2020 07:00 AM PDT Tiny diamond crystals could be used as an incredibly sensitive and small gravitational detector capable of measuring gravitational waves, suggests new research. |
| Hidden sources of mysterious cosmic neutrinos seen on Earth Posted: 01 Jul 2020 05:47 AM PDT A new model points to the coronoe of supermassive black holes at the cores of active galaxies to help explain the excess neutrinos observed by the IceCube Neutrino Observatory. |
| Scientists provide new explanation for the far side of the Moon's strange asymmetry Posted: 22 Jun 2020 06:50 AM PDT The Earth-Moon system's history remains mysterious. Scientists believe the two formed when a Mars-sized body collided with the proto-Earth. Earth ended up being the larger daughter of this collision and retained enough heat to become tectonically active. The Moon, being smaller, likely cooled down faster and geologically 'froze'. The apparent dynamism of the Moon challenges this idea. New data suggest this is because radioactive elements were distributed uniquely after the catastrophic Moon-forming collision. |
