Microscope Can Scan Tumors During Surgery

When women undergo lumpectomies to remove breast cancer, doctors try to remove all the cancerous tissue while conserving as much of the healthy breast tissue as possible. But currently there's no reliable way to determine during surgery whether the excised tissue is completely cancer-free at its margins...

Changing the Nature of Optics in One Step

Optical lenses that can see features smaller than the wavelength of light cannot be made from conventional materials. Creating “hyperlenses” that can take ultra-sharp images needs both designer materials (metamaterials) and innovative optics to be developed. Current methods for fabricating such...
