Breaking: Shell backs down in its lawsuit against Greenpeace

Just over a year ago, Shell sued Greenpeace UK, Greenpeace International and nine individuals for millions over a completely peaceful protest. We showed them their bully tactics won’t intimidate us – and now they’ve backed down and settled out of court.  And we’ve made sure not a penny of our supporters’ money will go to Shell. Here’s … Read more

The cost of convenience: Why ditching plastic is a justice issue

Plastic products have been marketed to us as innocuous items of convenience. Plastic bags, food containers, candy wrappers, packaging of all kinds, meant to make life easier on the go, or to protect our purchases from damage. A cheap and forgettable addition to our increasingly cluttered lives. But of course, these petrochemical by-products are far … Read more

Spotlight on nature protection at COP 29

Preserved Forest Area in the Realidade District, Humaitá, Amazonas © Greenpeace Brasil Just ten days after Nature COP took place in Cali, Colombia, high-level negotiations kicked off at the annual climate summit or COP29, in Baku, Azerbaijan. While the Nature summit closed with some wins and some frustration on finance ambition, the climate summit now … Read more

Setting the scale: the life and work of Anders Celsius

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  … Read more

Cloudy with a chance of warming: how physicists are studying the dynamical impact of clouds on climate change

For all of us concerned about climate change, 2023 was a grim year. According to the World Meteorological Organisation (WMO), it was the warmest year documented so far, with records broken – and in some cases smashed – for ocean heat, sea-level rise, Antarctic sea-ice loss and glacier retreat. Capping off the warmest 10-year period … Read more

Venkat Srinivasan: ‘Batteries are largely bipartisan’

Which battery technologies are you focusing on at Argonne? We work on everything. We work on lead-acid batteries, a technology that’s 100 years old, because the research community is saying, “If only we could solve this problem with cycle life in lead-acid batteries, we could use them for energy storage to add resilience to the … Read more

Physics-based model helps pedestrians and cyclists avoid city pollution

Follow the particulates: Snapshot of airborne pollution produced when a car brakes. (Courtesy: Adapted from Si, Run and Stafford, Jason 2024 R. Soc. Open Sci. 11 241111)http://doi.org/10.1098/rsos.241111) Scientists at the University of Birmingham, UK, have used physics-based modelling to develop a tool that lets cyclists and pedestrians visualize certain types of pollution in real time … Read more

Operando NMR methods for redox flow batteries and ammonia synthesis

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 … Read more

Rheo-electric measurements to predict battery performance from slurry processing

The market for lithium-ion batteries (LIBs) is expected to grow ~30x to almost 9 TWh produced annually in 2040 driven by demand from electric vehicles and grid scale storage. Production of these batteries requires high-yield coating processes using slurries of active material, conductive carbon, and polymer binder applied to metal foil current collectors. To better … Read more
