| Wind and solar could power the world’s major countries most of the time Posted: 05 Nov 2021 10:46 AM PDT With the eyes of the world on the United Nations COP26 climate summit in Glasgow, Scotland, strategies for decarbonizing energy infrastructure are a trending topic. Yet critics of renewables question the dependability of systems that rely on intermittent resources. |
| Electron family creates previously unknown state of matter Posted: 05 Nov 2021 10:46 AM PDT Researchers have demonstrated a completely novel state of matter in a metal. It is created by the combination of four electrons -- until now, only electron pairs were known. This discovery could lead to a new type of superconductivity, an entirely new research direction, and revolutionary technologies such as quantum sensors. |
| Experts master defects in semiconductors Posted: 05 Nov 2021 10:46 AM PDT Researchers have discovered a novel way to manipulate defects in semiconductors. The study holds promising opportunities for novel forms of precision sensing, or the transfer of quantum information between physically separate qubits, as well as for improving the fundamental understanding of charge transport in semiconductors. |
| Just a game? Study shows no evidence that violent video games lead to real-life violence Posted: 05 Nov 2021 05:41 AM PDT As the latest Call of Duty video game is released in the UK today, and with Battlefield 2042 and a remastered Grand Theft Auto trilogy to follow later this month, new research finds no evidence that violence increases after a new video game is released. |
| Polymer-coated nanoparticles to promote drug delivery to the brain Posted: 05 Nov 2021 05:40 AM PDT Researchers are optimizing polymer-coated nanoparticles to increase their permeability across this barrier and consequently the delivery of encapsulated drugs in the brain. |
| Posted: 04 Nov 2021 01:26 PM PDT Researchers have developed a control framework that enables robots to understand what it means to help or hinder one another and incorporate social reasoning into the tasks they are accomplishing. |
| Repurposing carbon dioxide may be key to net-zero emissions Posted: 04 Nov 2021 01:26 PM PDT While only a mere 4% of the atmosphere, carbon dioxide plays a vital role in sustaining life on our planet. However, if this delicate balance is disrupted, excess carbon dioxide can pose a formidable threat to our environment and the living beings that reside within. |
| Lake’s radioactivity concentration predicted for 10,000 days after the Fukushima accident Posted: 04 Nov 2021 08:53 AM PDT Researchers investigated the long-term contamination of Lake Onuma in Japan resulting from the 2011 Fukushima Daiichi nuclear disaster. They devised a formula based on a framework known as the fractional diffusion model to predict the radioactive contamination of the lake for up to about 30 years after the Fukushima accident. The results suggest that the decrease in radioactivity concentration will be slower than predicted by the conventional two-component decay function model. |
| Novel tag provides first detailed look into goliath grouper behavior Posted: 04 Nov 2021 07:06 AM PDT A new study reveals detailed behavior of massive goliath groupers. Until now, no studies have documented their fine-scale behavior. What is known about them has been learned from divers, underwater video footage, and observing them in captivity. Using a multi-sensor tag with a three axis accelerometer, gyroscope and magnetometer as well as a temperature, pressure and light sensor, a video camera and a hydrophone, researchers show how this species navigates through complex artificial reef environments, maintain themselves in high current areas, and how much time they spend in different cracks and crevices -- none of which would be possible without the tag. |
