Surprise! These animals can help fight climate change
Some animals help fight climate change by boosting the amount of carbon dioxide that plants, algae and bacteria absorb from the atmosphere.
- Environment
To limit pollution, new recipe makes plastic a treat for microbes
Microplastics made from fossil fuels take centuries to disappear. But the plant- and algae-based plastic can break down in weeks to months.

With measles outbreaks in 49 countries, should you worry?
By March, the United States had more measles cases than in all of 2023. It was part of a global trend. The way to halt measles’ spread: vaccinations.
- Archaeology

The findings challenge a common idea about how the mummified man got marked with dark lines.
- Animals
Dancing spiders inspired this biologist to teach others
Inspired by his research in animal communication, Echeverri began exploring ways to teach others about science while finishing his Ph.D. Today, he shares his passion for spiders as a science communicator.
- Chemistry
Air pollution can make it harder for pollinators to find flowers
Pollutants that build up in night air can break down the scents that attract pollinating hawkmoths to primrose blooms, disrupting their pollination.
- Animals
Among mammals, males aren’t usually bigger than females
In a study of more than 400 mammal species, less than half have males that are heavier than females.
- Health & Medicine
A new type of immune cell may cause lifelong allergies
These special memory cells were present in people with allergies and absent in those without.
- Plants
On hot summer days, this thistle stays cool to the touch
Its yellow flowers can cool themselves substantially, staying up to 10 degrees C (18 degrees F) cooler in extreme heat.

Experiment: Can plants stop soil erosion?
Soil erosion washes pollutants into streams and rivers — but plants may help limit that.
- Animals
Tardigrades survive harsh conditions by almost dying. Here’s how
Under stress, a chemical change signals these water bears to switch between live and mostly dead.
