One of the best ways to analyze Earth's past climate is with samples drilled from deep ice cores. Now, scientists have dated what may be the world’s oldest ice core, with some sections potentially preserving samples as old as 5 million years.

UC Berkeley chemists say they've created a simple, and very inexpensive way to capture carbon dioxide using a polymer called melamine, that's far cheaper than metal-organic frameworks. It could capture carbon emissions from smokestacks or tailpipes.

Siemens Gamesa has developed a fully recyclable blade that can be used to create new products when its wind-catching days are done, and it's just been installed on a turbine at a commercial wind farm in the North Sea.

Microplastics are a major environmental problem, but a new study could help cut out a decent chunk of them. Silk could be a biodegradable replacement for microbeads and particles that are often added to cosmetics, paints and other products.

We're seeing a growing emphasis on direct air capture technology in our efforts to combat climate change, and an interesting new take on this technology could see it put to use on railways around the world.

As an unprecedented heatwave takes hold in Europe, driving the mercury to record levels and causing devastating wildfires across the continent, authorities are scrambling to prevent disruptions to transport services.

Researchers stationed in Antarctica have been left mesmerized by the skies overhead, brought on by the aftereffects of a volcanic eruption and captured in jaw-dropping, unedited images by science technician Stuart Shaw.

Whether they're in cars, buildings or airplanes, most of today's noise-blocking acoustic tiles are made of petrochemical-derived foam. A more eco-friendly alternative may be on the way, however, in the form of seaweed-derived membranes.

A compound called salicylic acid is naturally produced when plants encounter things like drought and heat, and a new study demonstrates how this process might be leveraged to protect crops in the face of rising global temperatures.

Scientists in the Netherlands studying the spread of microplastics have turned their eye to meat and dairy products and discovered high rates of contamination in farm animals, raising new questions around the widespread nature of plastic pollution.

Microalgae is already being used as a fish-free alternative to the fish feed commonly used in aquaculture operations. Taking things a step further, scientists are now looking at using the plant-like organisms to replace the prawns eaten by humans.

Scientists studying plastic pollution in the UK have turned their eye to small land mammals and found traces of the material in more than half the species sampled, with a seemingly equal distribution across locations and even dietary habits.

Scientists have come up with a novel cleanup solution for microplastic pollution that takes its cues from nature, in the form of a fish-like robot that can move through the water and soak up small plastic fragments as it goes.

Swiss outfit Climeworks has today broken ground on its second direct air capture plant in Iceland, and one that marks significant progress in its ambitions of removing gigatons of CO2 from the atmosphere each year by 2050.

Scientists have discovered a genetically distinct subpopulation of polar bears that has adapted to survive on glacier slush instead of sea ice for large parts of the year, boding well for adaptability of the species.
