Lego down! Focused vibrations knock over minifigures

A tabletop covered in miniature Lego minifigures. There is a whooshing sound, a pause, and then a single minifigure in the center of the table topples over, leaving the remaining minifigures standing.

Super-fine sound beam could one day be an invisible scalpel

A carbon-nanotube-coated lens that converts light to sound can focus high-pressure sound waves to finer points than ever before. The University of Michigan engineering researchers who developed the new therapeutic ultrasound ...

Nanotube therapy takes aim at breast cancer stem cells

Wake Forest Baptist Medical Center researchers have again proven that injecting multiwalled carbon nanotubes (MWCNTs) into tumors and heating them with a quick, 30-second laser treatment can kill them.

Researchers effectively treat tumors with use of nanotubes

By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice. Researchers say ...

Making tumor diagnosis kinder to kidneys

Researchers at the Paul Scherrer Institute PSI, in collaboration with ETH Zurich, have optimized a method for tumor diagnosis using radionuclides. Potential side-effects can now be significantly reduced through a molecular ...

Sweet nanoparticles trick kidney

In the past decade nanomedicine has contributed to better detection and treatment of cancer. Nanoparticles are hundreds of times smaller than the smallest grain of sand and can therefore easily travel in the blood stream ...

Doctors embrace social networking

In the waiting room, the patient's family members circled a Blackberry. About every 15 minutes, Dr. Carlos Wolf of Miami Plastic Surgery gave them a few keystrokes of information about how the patient was doing.

Study reveals how a common virus eludes the immune system

Viruses have numerous tricks for dodging the immune system. In the September 7, 2009 issue of the Journal of Cell Biology, Stagg et al. reveal a key detail in one of these stratagems, identifying a protein that enables cyto-megalovirus ...
