Jane Goodall has died at 91.

Her startling observations about chimpanzee behaviors revolutionized not only scientific understanding of the capabilities and inner lives of primates, but also long-held notions about what it means to be human. https://wapo.st/476clLO

Hear that? It’s 2 a.m. You’re in bed. The sun hasn’t risen, but the robin has. It is 🎶-ing at an unnatural hour, waking you.

If this has happened to you, you’re not alone. Artificial light is prompting birds to tweet for nearly an extra hour a day on average.

These birds won’t stop singing, and it’s our fault

These crabs probably saved your life. Can we save theirs?

The medical world relies on horseshoe crab blood in the production of vaccines and equipment. A synthetic is available, but companies have been slow to adopt it.

Knowing why they're wasting is key to breeding resistant starfish and restoring ecosystems. But not every scientist agrees the bacterium is behind the disease.

Even if it is, it will take a lot of work to bring them back (3/3)

It starts with a twist. One arm pretzels in on itself. Then another... and another...

Before long, the arms detach and crawl away zombielike

We finally may be able to rid the world of mosquitoes. But should we?

Gene editing holds the potential of suppressing mosquito species that carry deadly diseases — and raises ethical questions.

The Post’s staff also received a Pulitzer finalist nod in national reporting for coverage that helped awaken the nation to the disaster of Hurricane Helene, revealing the scale of the destruction and human toll for the climate-fueled weather calamity.

In North Carolina, there was before Helene. This is the after.

“A hundred years from now, they will be talking about this flood,” said one resident in Western North Carolina, where the extent of the disaster is only beginning to emerge.
