Trees might not be acting in the way we thought - this forest fitted with pipes can tell us why

By simulating the future atmosphere, scientists hope to understand whether trees will continue to act as the lungs of the planet.

"The oak is the queen of her domain," says Rob MacKenzie as he gestures towards a giant towering above us. This oak tree has stood in this very spot since long before he or I walked the Earth. 

Chlamydia could make koalas extinct. Can a vaccine save them in time?

On the table, unconscious and stretched out on a pillow, Joe Mangy looks deceptively peaceful. The koala's watery, red-rimmed eyes are the only sign of the disease at war with his body.

Cal Academy Adds Over 100 New Species to the Library of Life in 2024

New species of sea slug, Bermudella lahainensis. 

Researchers at the California Academy of Sciences have unveiled a list of all the new animal, plant and fungi species that they added to the Library of Life in 2024.

The new species include a pygmy pipehorse camouflaged in sponges found off the coast of South Africa, an edible and endangered Oaxacan dahlia that looks like a succulent, and 136 other fishes, leaf bugs, worms, sea slugs, spiders, ghost sharks and more.

These discoveries expand our understanding of Earth’s biodiversity. Below, KQED has compiled a list of some of the most eye-catching of the new plants and critters.

Arctic tundra now emits planet-warming pollution, 2024 federal report finds

The Arctic tundra is warming up and that's causing long-frozen ground to melt as well as an increase in wildfires. The region is "now emitting more carbon that it stores, which will worsen climate change impacts," explained NOAA Administrator Rick Spinrad in a statement.

Arctic tundra, which has stored carbon for thousands of years, has now become a source of planet-warming pollution. As wildfires increase and hotter temperatures melt long-frozen ground, the region is releasing greenhouse gases into the atmosphere.
