Can light itself cast a shadow? It may sound like a philosophical riddle, but researchers have found that under certain ...

The type of laser most often used is a carbon dioxide laser. Laser surgery through the mouth is a treatment for early stage and locally advanced laryngeal cancers. This treatment might not be suitable ...

Israel's 'Iron Beam', designed to use high-power laser to down projectiles, will be operational within a year, according to reports. The laser defense system will complement the country's Iron ...

Israel expects its “Iron Beam” laser defense system to be operational within one year, saying it will bring “a new era of warfare” as it engages in a war of drones and missiles with Iran ...

A laser level can fix that. You wouldn’t fire up the circular saw without using a tape measure and square first, and you shouldn’t eyeball what plumb and level are, either. Sure, you could hang plumb ...

Scientists have found that plants absorb 31% more carbon dioxide than previously estimated, improving climate predictions and highlighting the importance of natural carbon sinks. The new estimate of ...

A typical large tree can suck as much as 40 kilograms of carbon dioxide out of the air over the course of a year. Now scientists at UC Berkeley say they can do the same job with less than half a ...
