An inexpensive paper sensor along with a smartphone-based reader can rapidly provide information on a person's personal smoke exposure during wildfire season.

A sponge-like device that captures water from thin air and then releases it in a cup using the sun's energy, even in low humidity where other technologies such as fog harvesting and radiative cooling have struggled.

Using a thermal sensor smaller than a grain of sand, engineers have measured the vibrations, or phonons, within individual molecules.

A new electronic skin sensor uses magnetic cilia to detect both pressure and magnetic fields for applications in health and touchless interfaces.

Researchers have developed a new type of pipette that can deliver ions to individual neurons without affecting the sensitive extracellular milieu. Controlling the concentration of different ions can provide important insights into how individual braincells are affected, and how cells work together.

Microcombs offer a compact, energy-efficient way to boost data transmission speeds beyond one petabit per second, helping solve global bandwidth bottlenecks.

Label-free nanophotonic sensing enables ultrasensitive protein and EV detection, offering a noninvasive, real-time alternative to traditional diagnostic methods.
