Right now, such tattoos don’t exist, but the key technology is being worked on in labs around the world, including my lab at ...

A team of scientists has made the first experimental measurements of laser-induced motions of miniature lightsails in the lab.

While such light-induced transitions have been observed before, Gedik notes that they typically only last for picoseconds. The technique works because the terahertz source stimulates the atoms in the ...

For precision, speed, and fine-detail, only the best laser engraver will make the cut. I tested out a range of laser engraving machines, and these are my top-rated recommendations for crafters ...

Noise-induced hearing loss can be temporary or permanent. It’s not as much a matter of how loud a sound seems, but how forcefully the sound waves enter the structure of your ear. If someone ever ...

In the COVID-19 pandemic era, at-home, portable tests were crucial for knowing when to wear a mask or isolate at home. Now, ...

The best laser printer is often the top choice for office and home office use. Excelling at document printing, laser printers have a reputation for producing crisp text, fast print speeds ...

Inspired by the unique geometry of natural oxalis leaves, we here propose a novel approach that includes preetching, growth, and transfer process to fabricate laser-induced graphene (LIG) with a ...
