Bacterial ‘living wires’ could help protect the seas and climate
Long, thin bacteria that conduct electricity may be able to help clean up oil spills and reduce emissions of methane, a powerful greenhouse gas.

Eight billion people now live on Earth — a new record
The global population hit this milestone on November 15, according to an estimate from the United Nations.

Let’s learn about eating bugs
Eating more insects, rather than pork, beef or other kinds of meat, may be better for the planet.

Let’s learn about microplastics
Microplastics have turned up everywhere from the highest mountains to the bottom of the ocean — and even inside animals and people.

Some spikes in malaria cases may be tied to amphibian die-offs
Amphibian deaths from a fungal disease may have led to more mosquitoes — and an increase in malaria cases in Costa Rica and Panama.
- Climate
Heat waves appear more life-threatening than scientists once thought
This is bad news as a warming planet leads to growing numbers of excessive heat waves — and millions more people facing potentially deadly temperatures.

Palm-size marsupials may face extinction from wild ‘house’ cats
After surviving Australian bushfires, the Kangaroo Island dunnart is losing ground as it's targeted by hungry predators.

Let’s learn about amphibians
Amphibians are named after the Greek word for “double life” because many transform from water dwellers to landlubbers as they grow up.

Your bloodstream may be littered with the plastic you’ve eaten
For the first time, scientists have found plastic particles circulating in human blood. No one yet knows whether those polluting bits might pose a risk to health.

Ponds made to control floods can spew climate-warming gases, study finds
Younger stormwater ponds can release more carbon in gases than they absorb, a study finds. That could aggravate global warming.

Analyze This: Corals stash microplastics in their skeletons
Scientists have wondered where the ocean’s microplastic pollution ends up. Corals may trap about 1 percent of particles in tropical waters each year.

UN report calls for two-pronged approach to slow climate impacts
The latest IPCC climate change report underscores an urgent need for action to avoid the worst consequences of global warming.
