Inside the control room, physicists and engineers cautiously shot the beam down part of the tunnel, stopping it before it went all the way around.

在控制室内，物理学家和工程师们小心翼翼地在隧道的一部分将光束击落，在其完成全程之前把它拦截下来。

During that test, an onboard calorimeter captured the laser beam before it left the aircraft.

在这次测试中，机载的计量器在激光波束离开飞机时捕捉到了它。

While there's more experiments and development to go before we ever see a tractor beam at the hospital, the achievement brings us one step closer to the sci-fi future we were always told we'd get, right alongside the personal communicators and jetpacks.

ENGADGET: Researchers build a working tractor beam, on a very small scale

They would thus stick like limpet mines to clots, before being burst by an ultrasonic beam to wash the clots away.

But before worrying about the mote in a distant polluter's eye, it makes sense to consider the beam in thine own.
