| Novel quantum effect discovered in naturally occurring graphene Posted: 06 Oct 2021 01:01 PM PDT Under special circumstances, the electrical resistance of a material can adopt a fixed value that is independent from the basic material properties and 'quantized'. This 'quantization' normally occurs within strong magnetic fields at very low temperatures when electrons move in two-dimensions. Now, a research team has succeeded in demonstrating this effect at low temperatures in the almost complete absence of a magnetic field in naturally occurring double-layer graphene, just two atoms thick. |
| LEONARDO, the bipedal robot, can ride a skateboard and walk a slackline Posted: 06 Oct 2021 01:00 PM PDT LEO carves out a new type of locomotion somewhere between walking and flying. |
| Highly porous rocks responsible for Bennu's surprisingly craggy surface Posted: 06 Oct 2021 01:00 PM PDT Using data from NASA OSIRIS-REx mission, scientists concluded that asteroids with highly porous rocks, such as Bennu, should lack fine-grained material on their surfaces. |
| Dwarf planet Vesta a window to the early solar system Posted: 06 Oct 2021 11:34 AM PDT The dwarf planet Vesta is helping scientists better understand the earliest era in the formation of our solar system. Two recent articles use data from meteorites derived from Vesta to resolve the 'missing mantle problem' and push back our knowledge of the solar system to just a couple of million years after it began to form. |
| How ‘ice needles’ weave patterns of stones in frozen landscapes Posted: 06 Oct 2021 10:49 AM PDT Experiments and modeling work offers new insights into the striking patterns of repeating stones seen in frost-prone landscapes. |
| Smart parrots need more stimulation Posted: 05 Oct 2021 04:09 PM PDT The smarter the bird, the more unique welfare needs it has in captivity, according to a new study that helps to explain why many intelligent animals struggle in captivity. The findings are also important to owners of intelligent birds to ensure they provide them with naturalistic diets rather than processed foods. |
