Tropical forests: human intervention changes tree species diversity

These small particles are reminiscent of paper flowers or desert roses. Physicians can use them to guide medicines to a precise destination within the body. Better yet, the particles can easily be tracked using ultrasound as they scatter sound waves.

Researchers have built a drone that can walk, hop, and jump into flight with the aid of birdlike legs, greatly expanding the range of potential environments accessible to unmanned aerial vehicles.

An interdisciplinary study from the University of Bern reveals that gut bacteria play a crucial role in converting arsenobetaine into toxic arsenic compounds. Results show that arsenobetaine, commonly found in seafood and previously considered harmless, is partly transformed into toxic arsenic compounds by the action of gut bacteria in the mammalian body. These findings raise new questions about the safety of seafood consumption.

For millennia humans have been inspired by the stars but this may soon be a thing of the past due to a significant increase in the numbers of satellites, potentially limiting our view of the night sky. scientists are part of a global initiative to better protect Earth's Dark and Quiet Skies.
