New trigger for self-powered mechanical movement
This image illustrates pumping in two directions at once with an enzyme patch. A patch of enzymes immobilized on a surface acts as a fluid pump. The fluid, and the small particles (green spheres) carried by the fluid, can simultaneously be pumped away from the patch (blue) in some parts of the chamber and toward the patch (red) in other locations. This behavior changes over time and is due to the changes in fluid density that the reaction produces. Credit: University of Pittsburgh
New clues in the hunt for the sources of cosmic neutrinos
This illustration is an example of a hidden cosmic-ray accelerator. Cosmic rays are accelerated up to extremely high energies in dense environments close to black holes. High-energy gamma rays (marked by the “Y” gamma symbol) are blocked from escaping, while neutrinos (marked by the “V”nu symbol) easily escape and can reach the Earth.
