ROS (Reactive oxygen species) are reactive oxidants in plant cells, including hydrogen peroxide (H2O2), superoxide anions (O2•−) and hydroxide anion radicals (·OH), which may stimulate the antioxidant system of plants and act as signaling molecules to regulate downstream reactions.

They seize suburbs.

Many contemporary studies have used methods designed to study dogs—a poor proxy, as our furry friends have fewer facial expressions than their ancestors.

(These techniques have previously been used to study facial expressions in cats.)

These expressions were common to all of the gray, arctic, and Canadian wolf packs the researchers observed.

However, this coding mechanism is not necessarily transferable to other locust species.

In experiments, they observed that the ants treated their nest members' femur injuries by cleaning the wound with their mouths before amputating the leg by repeatedly biting it, while the tibia wounds were treated with just cleaning.

The scientists are now extending their research to other ant species that don't possess special antimicrobial glands to see if other ants have the ability to perform surgeries.
