A team led by Gabriel Blaj, a staff scientist at the SLAC National Accelerator Laboratory and Stanford University, has generated what may be the loudest possible underwater sound.

Researchers have, for the first time, used a semiconductor laser to send and receive radio signals. The hybrid electronic-photonic device uses a laser to extract and transmit microwave signals, providing a data rate that may one day lead to ultra-high-speed Wi-Fi.

Getting a tattoo certainly isn't known for being a comfortable process. It can also cause damage to the skin, plus it results in bio-hazardous used needles that need to be properly disposed of. A new needle-free technique, however, gets around all of those problems.

In 2015, a century-old prediction by Einstein was finally proven correct, as gravitational waves were detected for the first time. Now, the facilities behind this discovery, LIGO, are back up and running after a year-long upgrade, with a few new tricks up their sleeves.

Some people think it's funny to shine laser pointers at aircraft that are taking off or landing. Unfortunately, though, the glare of the lasers can temporarily blind pilots, potentially leading to crashes. Installed in planes' windshields, new liquid crystal technology may keep that from happening.

Traditionally, welding has been limited to materials that share similar properties. But now, scientists are claiming a breakthrough method that can weld together materials as different as glass and metal, thanks to ultrafast laser pulses.

Although it's already possible to create colored images on metal surfaces using lasers, different TYPES of lasers have to be used for different effects. Now, however, Russian scientists have developed a method of producing multiple effects using one commercially-available laser.

Diamond is a useful material, but its relative rarity on Earth makes it difficult to get. Now, researchers at NCSU have demonstrated a new way to convert carbon nanofibers and nanotubes into diamond fibers that can be performed in a lab more easily than existing techniques.

In the modern day, we’re used to sending messages to people over long distances, usually by way of a phone. But now, scientists at MIT have developed a way to use a laser to beam an audible message through thin air to a person standing on the other side of a room, so that only they can hear it.

NASA is poised to send larger and larger telescopes into space over the next couple of decades and a team of researchers at MIT is working out how to use laser-equipped CubeSats to keep them fixed on target.
