A new formula protects against both UV light and heat from the sun using radiative cooling. The prototype sunblock kept human skin up to 6 C cooler than bare skin, or around 3 C cooler than existing sunscreens.
Opening new doors for the development of nanotechnologies in medicine and other fields, scientists recreate and compare two natural mechanisms to better program the timescale of molecular communication and functionality.
Researchers have forced light to travel in very different and unusual ways. Using nifty engineered chip-nanostructures, they observed that photons hop in a crystal lattice from one site to another, similar to how pieces move on a Go or checkers board, yet in 3D.
Scientists have developed porous ceramic materials that host living bacteria, enabling carbon capture from air and detection of harmful chemicals through biological processes.
A new way of thinking about how swirling magnetic textures and mobile electrons interact could lead to compact, efficient and robust electronic devices.
The technique provides researchers with a powerful tool for controlling magnetism, and could help in designing faster, smaller, more energy-efficient memory chips.
