Researchers in Tennessee have developed lasers that can map and then destroy cancerous tumors without damaging surrounding tissue. The technology uses a femtosecond laser, pulsing at speeds of one-quadrillionth of a second. Its speed allows it to focus in on one specific region to find and map the turmor. “Using ultra-short light pulses gives us [...]
Laser Device Performs Delicate Surgery

When surgeons use metal scalpels to cut away harmful tissue, there is a risk of cutting healthy tissue. This risk is especially acute for operations on critical organs, such as brains and intestines. Now there is a laser “scalpel” that targets diseased or damaged tissue while leaving healthy tissue intact. A team of researchers from [...]
