Let’s learn about taste
Taste tells us what’s good to eat, but scientists are still learning about how it works.

Some electric eels coordinate their attacks to zap prey
Electric eels were thought be to lone hunters — until researchers observed more than 100 eels hunting together. Their coordinated electric attacks corralled prey.
- Ecosystems
Can people protect as much space as nature needs?
To save biodiversity, nations are drafting a plan to protect 30 percent of Earth by 2030. Up for debate is how best to do that.

Honeybees fend off deadly hornets by decorating hives with poop
Bees usually collect pollen and nectar. Scientists were surprised to find that Asian honeybees also gather animal dung to defend their hives.

Explainer: Insects, arachnids and other arthropods
Arthropods are all around us, but identifying them can be hard. To start, look at the four main groups: chelicera, crustaceans, myriapods and insects.
- Chemistry
Scientists Say: Molecule
A molecule is a group of atoms linked with chemical bonds. It’s the smallest particle of a substance that has all of its chemical properties.

Dew collector brings water to thirsty plants
This invention grabs water from the air at night. All it needs is the sun’s warmth the next day to release that moisture to growing plants.

Camels have been dying after mistaking plastic for food
Plastic waste has been building up in the guts of some camels. It may now be killing off one percent of them in the United Arab Emirates each year.

Africa’s poisonous rats are surprisingly social
Scientists confirm that the African crested rat can safely cover itself in poison and also find that the rodents may live in pairs — or even family groups.
- Brain
Loneliness makes our brains crave people
An area of the brain that lights up when hungry people see food also revs up when lonely people see social activities.
- Brain
A taste map in the brain is a scattering of tiny flavor islands
Some senses are highly organized in the brain. Taste is not. And that points to just how important it is.

Touching allows octopuses to pre-taste their food
Special sensory cells in their arms’ suckers sense chemicals. Those cells allow them to taste the difference between food and poison.
