| Prehistoric shark hid its largest teeth Posted: 18 Nov 2020 11:17 AM PST Some, if not all, early sharks that lived 300 to 400 million years ago not only dropped their lower jaws downward but rotated them outwards when opening their mouths. This enabled them to make the best of their largest, sharpest and inward-facing teeth when catching prey, paleontologists have now shown using CT scanning and 3D printing. |
| Studies focus on SARS-CoV-2 transmission in domestic cats, pigs Posted: 18 Nov 2020 11:17 AM PST Two recently published studies include important findings related to SARS-CoV-2 transmission and the COVID-19 pandemic: Domestic cats can be asymptomatic carriers of SARS-CoV-2, but pigs are unlikely to be significant carriers of the virus. |
| Blue Ring Nebula: 16-year-old cosmic mystery solved, revealing stellar missing link Posted: 18 Nov 2020 11:16 AM PST Astronomers have solved the 16-year-old mystery surrounding the Blue Ring Nebula - an unusual, large, faint blob of gas with a star at its center. This object is unlike any they'd ever seen before in our Milky Way galaxy. The team has discovered the nebula appears to be the first known example of a merged star system at this stage. |
| 3D bioprinted heart provides new tool for surgeons Posted: 18 Nov 2020 11:16 AM PST Surgeons will soon have a powerful new tool for planning and practice with the creation of the first full-sized 3D bioprinted model of the human heart. |
| Geoscientists discover Ancestral Puebloans survived from ice melt in New Mexico lava tubes Posted: 18 Nov 2020 05:07 AM PST New study explains how Ancestral Puebloans survived devastating droughts by traveling deep into the caves of New Mexico to melt ancient ice as a water resource. |
| Could your vacuum be listening to you? Posted: 17 Nov 2020 06:01 PM PST A team of researchers demonstrated that popular robotic household vacuum cleaners can be remotely hacked to act as microphones. |
| Oil droplet 'predators' chase oil droplet prey Posted: 17 Nov 2020 04:26 PM PST Oil droplets can be made to act like predators, chasing down other droplets that flee like prey mimicking behavior seen among living organisms. |
| Large predatory fish thrive on WWII shipwrecks off North Carolina coast Posted: 17 Nov 2020 04:25 PM PST Results of an expedition to a sunken U-boat and Nicaraguan freighter offer a detailed glimpse into unexpected 'islands of habitat.' |
| Quantifying quantumness: A mathematical project 'of immense beauty' Posted: 17 Nov 2020 08:31 AM PST Large objects behave in accordance with the classical laws of mechanics formulated by Sir Isaac Newton and small ones are governed by quantum mechanics, where an object can behave as both a wave and a particle. The boundary between the classical and quantum realms has always been of great interest. Research now considers the question of what makes something 'more quantum' than another -- is there a way to characterize 'quantumness'? |
