Carbon

NASA’s Curiosity rover has detected high amounts of an unexpected form of carbon on Mars. That might not sound too exciting, but the kicker is that here on Earth, this chemical signature is usually associated with life.

A new method quickly converts carbon dioxide into solid carbon, which can be stored indefinitely or turned into useful materials. The technology works by bubbling CO2 up through a tube of liquid metal, and could be used at the source of emissions.

As 3D-printed electrical circuits become more widely produced, the problem of electronic waste could correspondingly get worse. That's why Swiss scientists have developed a new natural-source "e-ink" that biodegrades once discarded.

Researchers at Carnegie Science have developed an ultrahard diamond glass. Made entirely of crushed “soccerballs” of carbon, the new material also has high thermal conductivity and could find use in electronics.

The largest XPrize competition ever conducted has given out its first prize money, with 23 student teams receiving cash injections to further technologies that take aim at the problem of mounting carbon dioxide in the atmosphere.

Although the deep ocean floor may seem isolated from life on the rest of the planet, it actually plays a vital role in the carbon cycle. Scientists are now gaining a better understanding of that role, thanks to a tracked robotic underwater rover.

An ambitious startup called Climeworks is looking to eat into the world's carbon emissions and has just taken its biggest bite yet, flicking the switch on the largest direct air capture and CO2 storage plant on the planet.

Carbon dioxide in the atmosphere attracts most of the attention in environmental concerns, but much of that ends up in oceans, making them more acidic. Now scientists have created nanojars that can easily capture this and other pollutants from water.

Climate change can feel inevitable, but we’ve stepped up to the challenge before. New modeling shows how bad things would be if CFCs hadn’t been banned decades ago – depleted ozone would've increased UV exposure and stopped plants capturing carbon.

Ordinarily, airliners have to run their engines in order to taxi along the runway – this uses a lot of fuel, plus it generates a lot of CO2. A new in-ground towing system, however, offers what could be a more efficient and eco-friendly alternative.

Audeze helped design a pair of headphones to facilitate communication between doctor and patient during an MRI scan, without affecting the imagery produced. And this led to the development of the CRBN Electrostatic headphones for audiophiles.

Astronomers have counted the number of neutrons inside carbon atoms from 2.8 quadrillion km away. The team managed to measure the ratios of carbon isotopes in the atmosphere of an exoplanet for the first time, which can tell us about how it formed.
