Coin cells that utilize either a lithium metal or greatly oversized graphite negative electrode are common but can provide unrealistic testing results when compared to commercial pouch-type cells. Instead, single-layer pouch cells provide a more similar…

Region faces ‘extreme fire risk’ warnings and ‘significant risk of rapid fire spread’ as official death toll expected to riseAs forecasters warn of another “particularly dangerous weather situation” across northern Los Angeles, residents braced for new wildfire evacuation orders, even as the official death toll from last week’s fires in Altadena and the Pacific Palisades was expected to rise.Los Angeles, and parts of Ventura county to…

On Christmas Day in 1741, when Swedish scientist Anders Celsius first noted down the temperature in his Uppsala observatory using his own 100-point – or “Centi-grade” – scale, he would have had no idea that this was to be his greatest legacy. A newly published, engrossing biography – Celsius: a Life and Death by Degrees  – by Ian Hembrow, tells the life story of the man…

An innovative tech collaboration is helping to finesse a low-cost rubbish recycling process that relies on the insatiable appetite of black soldier fly larvae. Biotech company ARC Ento Tech, based on the NSW Central Coast, is helping to process landfill in the state by using the larvae of this common fly to eat the organic waste that’s part of mixed solid waste. Once all the organic…

Since January 5, 2025, vehicles are being tolled to enter the Congestion Relief Zone in Manhattan South, New York, under the Congestion Pricing Program of the City of New York.On February 19, 2025, the federal government, through the Department of Transportation, stated its disapproval of the program. A WhiteHouse social media post shows a TIME magazine-style cover featuring Trump wearing a crown with the text ‘Congestion pricing is…

Brice Böhmer is climate and environment lead at Transparency International. As the dust settles after COP29, a feeling of despondency and betrayal has set in. But amid the inevitable post-mortem, the international climate community must ask itself: are we really that surprised?  This is the third year running that a repressive petrostate has hosted COP, and the second where the summit – intended to help reduce…

New research out of the University of California, Davis and Stanford University has found that storing carbon dioxide in building materials could hugely reduce global greenhouse gas emissions. The study, conducted by civil engineers and earth systems scientists, has been published in the journal Science. “The potential is pretty large,” said Elisabeth Van Roijen, who led the study as a graduate student at UC Davis. Van…

The image below indicates that Arctic sea ice volume has meanwhile passed its annual maximum. Over the coming months, volume can be expected to decrease rapidly. The image also highlights that, over the past few months, Arctic sea ice volume has been the lowest on record for the time of year. The image below illustrates the decline of Arctic sea ice volume over the years. The…

Thirteen regional New South Wales councils have pooled their resources to make the shift to renewable energy via a power purchase agreement (PPA) coordinated by the Hunter Joint Organisation and Mid North Coast Joint Organisation. The Powering Tomorrow: Regional Councils NSW PPA will secure fixed pricing for the councils up until the end of 2030. Under the agreement, the councils will collectively receive over 390 gigawatt…

Magnetic resonance methods, including nuclear magnetic resonance (NMR) and electron paramagnetic resonance (EPR), are non-invasive, atom-specific, quantitative, and capable of probing liquid and solid-state samples. These features make magnetic resonance ideal tools for operando measurement of an electrochemical device, and for establishing structure-function relationships under realistic condition. The first part of the talk presents how coupled inline NMR and EPR methods were developed and applied to…

President Joe Biden has announced a US target to cut greenhouse gas emissions by 61-66% below 2005 levels by 2035, with White House officials saying the new goal can be achieved even if climate-change sceptic Donald Trump tries to roll back the country’s climate-action agenda. With just a month to go until President-elect Trump takes office, the outgoing administration called its updated Nationally Determined Contribution (NDC)…
