NASA green lights upgrade of Apollo era lunar laser experiment

The first laser retroreflector experiment was placed on the Moon by the Apollo astronauts

One of the original designers of a pioneering Apollo Moon experiment is leading an effort to create an upgraded version for future lunar landing missions. A team under professor emeritus at the University of Maryland (UMD), Doug Currie are developing a more accurate version of the Lunar Laser Ranging experiment that was left behind by Apollo 11, 14, and 15 between 1969 and 1971 that allows scientists to measure the distance from the Earth to the Moon extreme accuracy.

Review: LaserCube, the world's smallest – and first – battery-powered RGB laser projector

The LaserCube: difficult to catch on camera, but the way it makes light dance is absolutely ...

Wicked Lasers' latest gadget is one of the most mesmerizing and compelling toys we've played with in a long, long time. It's also extremely dangerous, powerful enough to pop balloons, etch patterns on wood, and surely fry the odd retina if used incorrectly.

Laser tech is set to measure earthquake damage to buildings

A diagram illustrating how the Discrete Diode Position Sensor works

How safe would you feel, going back into a multi-story building that had just been through an earthquake? A new sensor system could allay your fears, as it optically measures how much a building has swayed, and thus how damaged it may be.

Laser "pinging" shows promise for fast and cheap water testing

The current setup incorporates a laser tattoo removal machine that's hooked up to a fiber optic ...

Looking for impurities in drinking water or other liquids typically involves chemical analysis, which may be time-consuming. Now, however, scientists have created an inexpensive system in which light – that's converted to sound – is used to instantly determine if water is safe to drink.

US Special Forces laser can ID your heartbeat from over 600 feet away

In the mobile world, there are arguments over the accuracy and security of biometrics such as fingerprints, irises, and faces. In the security and military sectors, however, people are turning to heartbeats. Just like fingerprints, the cardiac signature of a person is believed to be unique and infallible. But unlike fingerprints, heartbeats can be measured secretly from a distance with … Continue reading

Cytophone detects and blasts circulating cancer cells

The Cytophone laser/ultrasound-based device in action detecting circulating tumor cells in the blood of patients with ...

A team from the University of Arkansas for Medical Sciences (UAMS) has developed a non-invasive tool which not only detects circulating tumor cells (CTCs) in the bloodstream, but can blast them away at the same time. Dubbed the Cytophone, it employs a laser which heats the CTCs, subsequently detecting them via ultrasound before turning up the heat again to kill them.

Moonrise to bring 3D laser printing to the lunar surface

Artist's concept of Moonrise in operation on the lunar surface

By combining moondust and lasers, Laser Zentrum Hannover (LZH) and the Institute of Space Systems (IRAS) of the Technical University of Braunschweig are experimenting with ways to use 3D printing to build lunar colonies. Slated to fly in 2021, the new Moonrise laser system will be incorporated in the Berlin-based PTScientists unmanned lunar rover and will be used to demonstrate if it is possible to turn lunar regolith into practical building materials.
