‘Vampire’ parasite challenges the definition of a plant

Langsdorffia are stripped down to their essentials. Lacking green leaves for photosynthesis, they steal energy and nutrients from other plants.

Agriculture

Scientists Say: Carbohydrate

Carbohydrates are molecules with carbon, oxygen and hydrogen. Animals break down these chemicals in food to get energy.

On an Alaskan glacier, little green moss balls roll in herds

Oval balls of moss, nicknamed ‘glacier mice,’ roll across some glaciers. A new study explores the mysteries behind their herd-like motion.

Bumblebees may bite leaves to spur plant blooming

In a pollen shortage, some bees nick holes in tomato leaves. This can speed up flowering and pollen production by weeks.

Plants

Silk-based microneedles may help treat diseased plants

Engineers have invented silk microneedles to inject medicines into plants. One day farmers might use drones to dart their sick plants with meds from the air.

Chemistry

Ancient recipes helped scientists resurrect a long-lost blue hue

Led by medieval texts, scientists hunted down a plant and used its fruit to make a blue watercolor with mysterious origins.

Plants

Let’s learn about trees

These long-lived woody plants provide shade for people, homes for animals — and help protect the planet against climate change.

5 things to know about the climate-saving benefits of tree planting

A recent analysis of the benefits of massive efforts to plant more trees triggered a firestorm of controversy.

Chemistry

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.
