A practical look at common tape measure use on the job site, with a focus on accurate measuring and better building habits. What small measuring mistake do you see most often? I’m a cardiologist – ...

A 2-in-1 digital laser tape measure can simplify home projects by combining two tools into one. This device features a 165-foot laser for large spaces and a 9.8-foot traditional tape for smaller jobs.

The U.S.military is paving the way for the regular deployment of high-energy laser weapons on American soil for air defense amid the expanding threat of low-cost weaponized drones. The Federal ...

The U.S. government can now use a counterdrone laser along the southern border after the Pentagon and Federal Aviation Administration (FAA) agreed the weapons are safe, the two agencies announced ...

Pulse ‘time of flight’ and interferometric measurement have long been two major approaches of laser ranging, with the former featuring simple and robust, suitable for long distance absolute ranging in ...

Scientists have taken lasers beyond light and into the realm of sound, creating a breakthrough “phonon laser” that manipulates tiny vibrations at the quantum level. By dramatically reducing noise in ...

Laser weapons are such an entrenched sci-fi trope that it's easy to forget just how real this tech can be (and is). While we're not exactly close to seeing real-life "Star Wars" space battles, the U.S ...
