Researchers at Purdue and Princeton universities have created a prototype firewall to block hackers from interfering with wireless medical devices such as pacemakers, insulin-delivery systems and brain implants.

Helping bridge the gap between photonics and electronics, researchers from Purdue University have coaxed a thin film of titanium nitride into transporting plasmons, tiny electron excitations coupled to light that can direct and manipulate optical signals on the nanoscale.

A new online application will help growers and pesticide consultants electronically track the number of insects in their crop fields so they can better control crop damage caused by insects and improve the use of insecticides.

Researchers are developing solar cells that might be manufactured using special ink printed onto sheets of a supporting material, an approach that could lead to new low-cost solar cells economically competitive with other energy technologies.

A two-year study of high school football players suggests that concussions are likely caused by many hits over time and not from a single blow to the head, as commonly believed.

The driving bass rhythm of rap music can be harnessed to power a new type of miniature medical sensor designed to be implanted in the body.

The smallest wires ever developed in silicon - just one atom tall and four atoms wide - have been shown by a team of researchers from the University of New South Wales, Melbourne University and Purdue University to have the same current-carrying capability as copper wires.

Researchers have created a new type of optical device small enough to fit millions on a computer chip that could lead to faster, more powerful information processing and supercomputers.
