Like a propeller, new drone spins too fast for the human eye to see clearly. It’s about 10 times less visually perceptible than a conventional quadcopter. AI designed and optimized the drone, determining ideal placement of each component to make it harder to see.
A comprehensive Cal Poly study examining North American bird population data reveals that environmental change does not affect all species equally. The research, assessing data collected across North America over nearly 30 years, found that no single environmental factor explained bird population changes across all species. Instead, species responded in highly individualized ways because of their interactions with their environment. While human-caused disturbances such as light pollution and air pollution can negatively affect bird populations, ecological traits can help predict species' sensitivity and forecast how well they will respond to ongoing environmental change. The study also highlights the importance of local conservation action. While climate change and regional air pollution require broad policy solutions, many environmental factors affecting birds can be addressed at the level of cities or counties.
Researchers have shown it is possible to expand the field of twistronics – literally. The researchers have demonstrated a technique allowing them to fabricate oxide twistronic materials at much larger sizes, while also controlling the twist angles between materials that dictate their structural and electronic properties.
Driving an electric current through a molecule can create a magnetic field. Yet in practice, such fields are often too weak to be detected experimentally. Through theoretical modeling, researchers at the Institute of Science and Technology Austria (ISTA) show how quantum effects can turn single molecules into effective magnets—including one shaped like a microscopic soccer ball, just in time for the FIFA World Cup final. The findings were published in Nature Communications.
