Sensor promises disease detection with naked eye

British scientists have come up with a super-sensitive prototype sensor that lets doctors detect early stage diseases with the naked eye, an innovation that could prove valuable in countries that lack the resources for expensive diagnostic equipment.

The sensor, created at Imperial College London, relies on nanotechnology to analyze serum derived from blood samples.

A positive reaction to p24, a protein that indicates early HIV infection, or PSA, a protein that at certain levels can indicate prostate cancer, generates irregular clumps of nanoparticles that emit a blue color in a solution kept in a disposable container.

A negative reaction, however, … Read more

Group promotes savings with open-source software

For about a year, a group of heavyweight automotive and technology companies has been working on a way to hasten development of in-vehicle entertainment systems. Their solution: share basic software development using the open-source Linux operating system.

Among the nearly 50 members of the group, called the Genivi Alliance, are automakers General Motors, BMW AG, Nissan Motor, and, as of February 17, Renault SA. Suppliers include Visteon, Delphi Automotive, and Continental AG.

The Genivi (pronounced jah-NEE-vee) Alliance is focusing on developing "middleware"--the layer of software that allows various kinds of information and entertainment applications to work together … Read more
