Australian company directors call for more infrastructure spending and a Green New Deal
Company directors want a more radical policy reset to recover from the Covid-19 recession including bigger investments in infrastructure, reforms of industrial relations and a Green New Deal. The Australian Institute of Company Directors’ sentiment index, released on Thursday, found…
Prebiotic chemistry: In the beginning, there was sugar
Organic molecules formed the basis for the evolution of life. But how could inorganic precursors have given rise to them? Chemists now reports a reaction pathway in which minerals catalyze the formation of sugars in the absence of water.
A renewable solution to keep cool in a warming world
(International Institute for Applied Systems Analysis) Month-on-month, year-on-year, the world continues to experience record high temperatures. In response to this and exacerbated by a growing global population, it is expected that air-conditioning demand will continue to rise. A new IIASA-led study explored the pros and cons of seawater air-conditioning as an alternative cooling solution.
Metal-poor globular cluster forces astronomers to rethink theories
The discovery of the most metal-poor globular cluster recorded to date has forced scientists to rethink how both galaxies and globular clusters form.
Energy system 2050: Solutions for the energy transition
To contribute to global climate protection, Germany has to rapidly and comprehensively minimize the use of fossil energy sources and to transform the energy system accordingly.
TECHNOLOGY: Analysts skeptical of ‘green hydrogen’ future
Bets on renewable energy-derived hydrogen in the fight against climate change likely will come up short, market analysts are now predicting.
Long-term data show a recent acceleration in chemical and physical changes in the ocean
(Bermuda Institute of Ocean Sciences) New research published in Nature Communications Earth & Environment uses data from two sustained open-ocean hydrographic stations (Hydrostation ‘S’ and the Bermuda Atlantic Time-series Study) in the North Atlantic Ocean near Bermuda to demonstrate recent changes in ocean physics and chemistry since the 1980s. The study shows decadal variability and recent acceleration of surface warming, salinification, deoxygenation, and changes in carbon dioxide (CO2)-carbonate chemistry that drives ocean acidification.
Physicists observe room-temperature superconductivity
Physicists have made a breakthrough in the long sought-after quest for a room-temperature superconductor, what they call the ‘holy grail’ of energy efficiency.
