Why Hurricane Helene was so devastating
The tempest caused record-breaking storm surge on the coast and widespread and deadly flooding and debris flows in the Appalachian Mountains.

Do science dioramas still have a place in today’s museums?
Science dioramas of yesteryear can highlight the biases of the time. Exhibit experts are reimagining, annotating — and sometimes mothballing — the scenes.

A biogeochemist is tracking the movements of toxic mercury pollution
Exposing the hidden movements of mercury through the environment can help reduce human exposure.

This protist unfolds its ‘neck’ up to 30 times its body length to scout prey
With geometry’s help, 'Lacrymaria olor' can extend its long, necklike protrusion in less than 30 seconds.

How did an ancient shark parasite end up fossilized in tree resin?
A worm preserved in 99-million-year-old amber resembles modern flatworms in shark intestines. The rare finding has scientists stumped.
- Genetics
Freeze-drying turned a woolly mammoth’s DNA into 3-D ‘chromoglass’
A new technique for probing the 3-D structure of ancient DNA may help scientists learn how extinct animals functioned, not just what they looked like.

Migratory fish species are in drastic decline, a new UN report details
The most comprehensive tally of how migrating animals are faring looks at more than 1,000 land and aquatic species and aims to find ways to protect them.

Tiger beetles may weaponize ultrasound against bats
In response to recordings of echolocating bats, tiger beetles emit noises that mimic toxic moths that bats avoid.
- Neuroscience
Lampreys have ‘fight or flight’ cells, challenging ideas about nervous system evolution
The discovery of sympathetic nervous system cells in lampreys draws a closer tie between the animal and complex vertebrates — such as humans.
- Animals
Glowing octocorals have been around for at least 540 million years
Genetic and fossil analyses shine a light on how long the invertebrates have had bioluminescence — a trait thought to be volatile.
