Shouting into the wind may seem futile — but it’s really not
Sending a sound upwind, against the flow of air, actually makes the sound louder — only it doesn’t sound that way to the person making the noise.

The inner workings of microscopes, telescopes, eyeglasses and other lens-based devices rely on two important laws of optics.
The rainbow palette and cooling powers of new plant-based films comes from their microscopic surface patterns of tiny crystals.
At Regeneron ISEF, three teens debuted an infrared system to detect honeybees carrying mites. It can show beekeepers when a colony needs to be treated.
In a mountaintop experiment, a laser beamed at the sky created a virtual lightning rod that snagged several bolts.
Keeping buildings cool can use a lot of energy. Thanks to quantum computing, engineers designed a coating to cut the warming light that enters windows.
Piezoelectric materials turn mechanical energy into electrical energy — and vice versa.
The internet has a big environmental footprint. But this new type of tech could help reduce the climate impact of computing.
The sun creates energy through nuclear fusion. Now scientists have too. This achievement raises hopes for developing a new type of clean energy.
Seismology is the branch of science focused on seismic waves — vibrations that run through or around Earth.
