Making organs transparent to improve nanomedicine

Treating a disease without causing side effects is one of the big promises of nanoparticle technology. But fulfilling it remains a challenge. One of the obstacles is that researchers have a hard time seeing where nanoparticles ...

The secret of resistance—shattering into a thousand pieces

Being all in one piece is not always a good strategy for resisting external strain. Biological tissues are well aware of it: they tend to crack simultaneously and gradually in several places, rather than catastrophically ...

A turning point in the physics of blood

Mike Graham knows that fluid dynamics can reveal much about how the flow of blood helps and hinders individual blood cells as they go about their work.

New technique detects microscopic diabetes-related eye damage

Indiana University researchers have detected new early-warning signs of the potential loss of sight associated with diabetes. This discovery could have far-reaching implications for the diagnosis and treatment of diabetic ...

Nanoparticles target anti-inflammatory drugs where needed

Researchers at the University of Illinois at Chicago have developed a system for precisely delivering anti-inflammatory drugs to immune cells gone out of control, while sparing their well-behaved counterparts. Their findings ...

A microchip for metastasis

Nearly 70 percent of patients with advanced breast cancer experience skeletal metastasis, in which cancer cells migrate from a primary tumor into bone—a painful development that can cause fractures and spinal compression. ...

Computer model predicts red blood cell flow

Adjacent to the walls of our arterioles, capillaries, and venules—the blood vessels that make up our microcirculation—there exists a peculiar thin layer of clear plasma, devoid of red blood cells. Although it is just ...
