The Wolf That Discovered California

Nearly a century after the last wolf was eradicated in the state, a lone female arrived and established a pack. Not everyone is cheering

Partially protected areas are often proposed as a way to bolster marine life and to improve people’s enjoyment of the ocean—neither of which seems to be happening.

Partially Protected Marine Areas Have Little Benefit, Scientists Say

Compared to fully safeguarded marine protected areas, the zones don’t show a lot of positive effects for marine life or people’s enjoyment

Sea beans, otherwise known as sea asparagus and pickleweed, belong to the genus Salicornia, marsh plants that thrive in salty soils.

Step Into the Mossy World Where Tiny Plants Play an Outsized Role in the Environment

Bryophytes are an important part of our environment, but in the tropics, there’s still much to learn about them

A blowfly on lavender flowers. Flies are the unsung heroes of pollination. They visit flowers to stoke up on energy-rich nectar and protein-rich pollen and transport pollen from flower to flower in the process.

How Much Do Flies Help With Pollination?

The much-maligned insect could be the key to ensuring future supplies of many of the world’s favorite foods

The cyanobacteria species that produces gatorbulin-1, tentatively identified as Lyngbya confervoides, forms these reddish-green, hair-like structures which are a collection of connected single cells rather than a true multicellular organism.

The health of corals on the Great Barrier Reef is routinely being threatened by hot water temperatures. The Australian government is investigating a range of techniques to try to protect the corals and stave off warming.

Could Flushing Cold Water Over the Great Barrier Reef Save Corals?

Lack of action on climate change is forcing scientists to devise ever more elaborate ways to stave off damage

Regenerative farming, which centers on building soil health, is one promising pathway for decreasing agriculture’s carbon footprint.

To Meet Ambitious Emissions Goals, Large Food Companies Are Looking to Lock Carbon in Soil

But the logistics of moving farmers in their supply chains to regenerative agriculture practices can be complicated

This is a giant spindle magnetofossil, created by a mysterious creature over 50 million years ago. So far, the iron fossils have only been found during two periods of intense global warming.
