Measuring ocean acidification is possible to an extent with sensors fitted to stationary buoys and vessels, but a newly fitted out deep-diving underwater drone promises to fill in the blanks in a big way.

Because seeds may contain yield-reducing fungi, bacteria or viruses, they're often chemically treated before they're sold to farmers. A new mobile system, however, substitutes microbe-killing electrons for harsh and eco-unfriendly chemicals.

Changing up the recipe could help roads last longer. Researchers in Australia have now shown another advantage of adding rubber from old tires to asphalt – extra Sun protection that could help roads last up to twice as long before cracking.

Scientists are beginning to explore the relationship between climate change and sleep quality, based on the premise that rising ambient temperatures are impacting our rest. And a new study indicates it may already be costing us many hours per year.

Scientists are ramping up their efforts to better break down dangerous PFAS "forever chemicals" before they can cause harm, and a new breakthrough demonstrates how this might be done in a matter of hours using UV light.

The US Department of Energy's efforts to combat climate change are set to receive a massive cash injection, with the Biden administration announcing US$3.5 billion in funding for regional direct air carbon capture hubs to help reach net-zero by 2050.

The latest climate change report from the World Meteorological Organization shines the spotlight on some of the important markers of climate change, detailing a string of alarming new records set across 2021.

Rare coral bleaching brought on by abnormal sea temperatures is rapidly becoming the norm on Australia's Great Barrier Reef, which has just experienced its fourth such event in six years, and the first to ever occur in a La Niña year.

The damage sunscreen can do to corals is tied to a common ingredient called oxybenzone, and Stanford scientists have now shown how corals convert the compound into a potent toxin that brings about their demise.

The sludge that is created through sewage treatment processes is rich in nutrients like phosphorous and nitrogen, making it an excellent source of fertilizer for agriculture. But research has found it also contains significant amounts of microplastics.

Invasive freshwater zebra mussels are a problem in many areas, clogging structures such as water intake and water treatment pipes as they rapidly reproduce. A new technology could help, by getting them to eat "eco-friendly" poison disguised as food.

Nike looks to make shoe recycling simpler with its new ISPA Link, a glue-less sneaker that quickly separates into three pieces to presort itself for recycling. The company hopes to scale the program to make sneaker recycling a more universal concept.
