| Seeing the universe through new lenses Posted: 14 May 2020 11:36 AM PDT A new study revealed hundreds of new strong gravitational lensing candidates based on a deep dive into data. The study benefited from the winning machine-learning algorithm in an international science competition. |
| The carnivorous plant lifestyle is gene costly Posted: 14 May 2020 10:17 AM PDT The genomes of three carnivorous plants -- the Venus flytrap, spoon-leaved sundew and the waterwheel plant -- have been decoded. The result has caused some surprises. |
| Dynamic stimulation of the visual cortex allows blind and sighted people to 'see' shapes Posted: 14 May 2020 08:58 AM PDT A team of investigators has described an approach in which implanted electrodes are stimulated in a dynamic sequence, essentially 'tracing' shapes on the surface of the visual cortex that participants were able to 'see.' |
| TRAPPIST-1 planetary orbits not misaligned Posted: 14 May 2020 08:57 AM PDT Astronomers have determined that the Earth-like planets of the TRAPPIST-1 system are not significantly misaligned with the rotation of the star. This is an important result for understanding the evolution of planetary systems around very low-mass stars in general, and in particular the history of the TRAPPIST-1 planets including the ones near the habitable zone. |
| Beads made of boa bones identified in lesser Antilles Posted: 14 May 2020 08:57 AM PDT Today Boa snakes have a patchy distribution in the islands that form the Lesser Antilles in the Caribbean Sea, but the constrictors are nearly absent from archaeological deposits in the region. Whether this scarcity is due to biological or cultural factors remains unknown. The current study describes the first Boa finds on Martinique, Basse-Terre and La Désirade, and provides a new hypothesis concerning the relationship between indigenous human populations and Boa prior to Western colonization. |
| Planetary exploration rover avoids sand traps with 'rear rotator pedaling' Posted: 13 May 2020 11:38 AM PDT Built with wheeled appendages that can be lifted and wheels able to 'wiggle,' a new robot known as the 'Mini Rover' has developed and tested complex locomotion techniques robust enough to help it climb hills covered with granular material -- and avoid the risk of getting ignominiously stuck on some remote planet or moon. |
| Microscopic feather features reveal fossil birds' colors and explain why cassowaries shine Posted: 13 May 2020 11:34 AM PDT Some birds are iridescent because of the physical make-up of their feathers, but scientists had never found evidence of this structural color in the group of birds containing ostriches and cassowaries -- until now. Researchers have discovered both what gives cassowary feathers their glossy black shine and what the feathers of birds that lived 52 million years ago looked like. |
| T. rex was a champion walker, highly efficient at lower speeds Posted: 13 May 2020 11:33 AM PDT A new study suggests that long legs evolved among the biggest dinosaurs to help them conserve energy as they ambled along searching for prey, rather than for speed as previously assumed. |
| Real-time physics engine for soft robotics Posted: 11 May 2020 04:35 PM PDT Scientists have adapted sophisticated computer graphics technology, used to create hair and fabric in animated films, to simulate the movements of soft, limbed robots for the first time. The advance is a major step toward such robots that are autonomous. |
