Scientists look to hack photosynthesis for a ‘greener’ planet
Photosynthesis turns sunlight into energy for plants. Scientists want to know more about it, imitate it — even improve it.
- Animals
Scientists Say: Species
This word describes organisms grouped by their similarities in genetics and physical traits. But defining species can be tricky.

Meat-eating pitcher plants feast on baby salamanders
Scientists didn’t think meat-eating plants in North America ate vertebrates. They now know differently.

A million species could vanish, and people are to blame
Human activities are putting a million plant and animal species at risk of extinction, a new study finds. But it’s not too late to save many of them, scientists add.
- Environment
City living makes trees grow fast but die young
Many cities plant trees to absorb carbon dioxide. But city trees grow fast and die young, which means they absorb less carbon dioxide than forest trees do.

Need a little luck? Here’s how to grow your own
A 2019 Intel ISEF finalist used a plant hormone and extra fertilizer to boost the numbers of multi-leafed clovers — including lucky four-leafed plants — she could reliably grow.

Warming pushes lobsters and other species to seek cooler homes
Plants and animals are moving toward the poles, changing timing of important events and more — all in response to climate change.
- Environment
Life on Earth is mostly green
A new survey of life on Earth finds that plants and microbes dominate. But even though humans are in the minority, they still play a major role.

This houseplant can clean indoor air
Houseplants may be able to help clean up polluted indoor air. Scientists gave this one a boost by givng it a gene from a rabbit.

Rare-plant hunters race against time to save at-risk species
One in five plants is at risk of extinction. Meet the rare plant hunters who rappel down cliffs and trek through forests to save them.
- Plants
Scientists Say: Nectar
Nectar is a fluid filled with sugar that plants — especially flowers — produce. They use it to attract animals that will then spread their pollen to another plant.

Plants don’t grow well when always on high alert
Plants make bitter-tasting chemicals to defend themselves against hungry bugs. But they pay a cost for always being on alert, scientists find.
