Spatiotemporal light pulses could secure optical communication by masking data

Using self-developed drones and advanced sensors, researchers can now see both under the snow and into the ground. The scientists' goal is to reduce societal risk and environmental encroachment.

Red foxes and birds regularly cross between human-dominated and natural ecosystems. For this reason, they may be heralds of spreading antibiotic resistance into ecosystems unexposed to antibiotic pressures, a study done in Italy showed. Results indicated that the share of K. pneumoniae isolates resistant to third-generation cephalosporins—a key group of hospital antibiotics—was about five times higher in wildlife than in isolates from human hospital patients. This shows that studying wildlife re

The circular geologic feature in northwestern Africa can be hard to recognize from the ground, but it is obvious when viewed from space.

When lightning strikes a paddock, it does more than scorch grass and scare the cows. The electrical discharge breaks apart nitrogen molecules in the atmosphere, converting them into a form that falls to Earth in rain and becomes available to plants. It is a natural process, primordial and efficient, which has been fixing nitrogen into soils long before humans began to farm them.
