Copper makes seed pods explode

Plants have evolved numerous strategies to spread their seeds widely. Some scatter their seeds to the wind, while others tempt animals and birds to eat their seed-filled fruits. And a few rare plants—such as the popping ...

Tracking weeds to stop them in their tracks

Not that long ago, weeds spread at a much slower rate. Seeds would spread to nearby soil and move perhaps a few feet each year or would be transplanted by birds who flew with them several miles away. In today's interconnected ...

Siberian tundra could virtually disappear by mid-millennium

Due to global warming, temperatures in the Arctic are climbing rapidly. As a result, the treeline for Siberian larch forests is steadily advancing to the north, gradually supplanting the broad expanses of tundra which are ...

New 'CRISPR-Combo' method boosts genome editing power in plants

Ten years ago, a new technology called CRISPR-CAS9, made it possible for scientists to change the genetic code of living organisms. As revolutionary as it was, the tool had its limitations. Like the first cell phones that ...

Research unveils evolution and seed micromorphology in Impatiens

The species Impatiens linnaeus is notoriously difficult to classify morphologically, and the semi-succulent stems, fleshy leaves, and extremely fragile flowers make it challenging to prepare good herbarium specimens. Compared ...
