A carbon footprint life cycle assessment can cut down on greenwashing
As companies try to reduce their carbon footprint, many are doing life cycle assessments to quantify the full carbon cost of their products.

A coral pollution study unexpectedly helped explain Hurricane Maria’s fury
Tracking coral reef pollution in Puerto Rico, conservation researchers discovered by chance how the coastal ocean fueled Hurricane Maria.

In 2021, a deadly volcano erupted with no warning. Here’s why
Before the Nyiragongo eruption, underground magma was already close to the surface and so didn’t trigger instruments that look for lava movement.

Not one, but two asteroids might have slain the dinosaurs
A craterlike structure found off West Africa’s coast might have been formed by an asteroid impact around the same time the dinosaurs went extinct.

Extreme climate shifts long ago may have helped drive reptile evolution
The end-Permian extinction left reptiles plenty of open ecological niches. But rapid climate change may be what kick-started the animals’ dominance.

Common, cheap ingredients can break down some ‘forever chemicals’
Forever chemicals, or PFAS, are harmful compounds that are very difficult to degrade. But some are no match for lye and dimethyl sulfoxide.

The Arctic is warming even faster than scientists realized
The Arctic isn’t just heating up two to three times as quickly as the rest of the planet. New analyses show that warming is almost four times as fast.

Sea sponges launch slow-motion snot rockets to clean their pores
Sea sponges rely on a sneezing mechanism to clear their pores, using mucus to flush out debris. This mucus provides food for other marine life.

Relocated beavers helped mitigate some effects of climate change
Along a river in Washington state, the repositioned beavers built dams that lowered stream temperatures and boosted water storage.
