More Polar Bear Climate Porn: Bears Use 4X More Energy In Computer Models

Last week (24 February 2021), The Guardian was promoting a study that claims polar bears now use four times more energy than expected to survive because of ‘major ice loss’ in the Arctic, as a way of suggesting that the…

Climate change vs agriculture: Can one farming method—conventional, organic or agroecology—help slow global warming? – Genetic Literacy Project

Climate change and agriculture appear joined at the hip. Agriculture—through methane, carbon dioxide, and land use—has had an impact on the global climate. And climate change—through drought, heat, and pests—will have an impact on agriculture, reducing yields and making farming…

Assessing the aggregate and spatial economic impact of global warming | VOX, CEPR Policy Portal – voxeu.org

The effects of climate change are heterogenous across space. While some regions will be significantly negatively impacted, others may benefit from warmer temperatures. This column uses an integrated assessment model with rich spatial data that looks at interactions between regions…

Mechanistic understanding of oxygen-redox processes in lithium-rich battery cathodes

(The Faraday Institution) Scientists based at the University of Oxford as part of the Faraday Institution CATMAT project researching next-generation cathode materials have made a significant advance in understanding oxygen-redox processes involved in lithium-rich cathode materials. The paper, published in Nature Energy, proposes strategies that offer potential routes to increase the energy density of lithium-ion batteries.

Scientists Use Novel Ink With Calcium to 3D-Print ‘Bone’ With Living Cells

3D printers may one day become a permanent fixture of operating rooms, now that Australian scientists showed they could print bone-like structures containing living cells. Scientists from UNSW Sydney have developed a ceramic-based ink that may allow surgeons in the future to 3D-print bone parts complete with living cells that could be used to repair […]

Scientists Achieve Breakthrough, Talking With Lucid Dreamers in Their Sleep—And There’s Now An App For That

Dreams take us to an alternative reality while we’re fast asleep. So, you might not expect that a person in the midst of a vivid dream would be able to perceive incoming questions and provide answers to them. But a new study led by Northwestern University researchers shows that, in fact, they can—and they developed […]

Cosmic ray originated in cataclysmic event

Astronomers found a high energy neutrino – a cosmic ray – that apparently originated during a “tidal disruption event,” that is, when a supermassive black hole shredded a distant star.

New Plant-Based Plastics Can be Chemically Recycled With Near-Perfect Efficiency

With plastic pollution creating such a monumental problem, and recycling technology being too often inefficient, there seems to be a new biodegradable, bio-based, or more easily dismantled conventional plastic polymer, invented every month. In 2020, GNN reported on plastic item bags made from minerals that dissolve in boiling water, biodegradable flip-flops made from algae, additives […]
