Laser "microscalpel" to target individual cancer cells

Mechanical engineering Assistant Professor Adela Ben-Yakar at The University of Texas at Austin has developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases.

Researchers develop brain-machine interfaces that learn with the brain

Devices known as brain-machine interfaces could someday be used routinely to help paralyzed patients and amputees control prosthetic limbs with just their thoughts. Now, University of Florida researchers have taken the concept a step further, devising a way for computerized devices not only to translate brain signals into movement but also to evolve with the brain as it learns.

New discovery could lead to new treatments for Alzheimer's

Rutgers researcher Karl Herrup and colleagues at Case Western Reserve University have discovered that a protein that suppresses cell division in brain cells effectively "puts the brakes" on the dementia that comes with Alzheimer's disease (AD). When the brakes fail, dementia results.

Precision control of DNA separation using an electric field

An electric voltage can be used to propel DNA molecules through a channel a few nanometers deep, or to stop them in their tracks. In a strong electric field the molecules judder along the channel, while in weaker fields they move more smoothly. This enables DNA fragments to be 'captured' on a chip and separated for analysis.
