Biomedical imaging at one-thousandth the cost

MIT researchers have developed a biomedical imaging system that could ultimately replace a $100,000 piece of a lab equipment with components that cost just hundreds of dollars.

Graphene flakes as an ultra-fast stopwatch

Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR), working with colleagues from the US and Germany, have developed a new optical detector from graphene which reacts very rapidly to incident light of all different ...

The light of fireflies for medical diagnostics

In biology and medicine, we often need to detect biological molecules. For example, in cancer diagnostics, doctors need quick and reliable ways of knowing if tumor cells are present in the patient's body. Although such detection ...

Researchers cross a critical threshold in optical communications

Researchers from Lehigh University, Japan and Canada have advanced a step closer to the dream of all-optical data transmission by building and demonstrating what they call the "world's first fully functioning single crystal ...

Small signaling molecule gives green light for cell division

Generating offspring is the evolutionary goal of all living organisms. The multiplication of individual cells is coordinated by the cell cycle. For the discovery of how this process is regulated in eukaryotes the Noble Prize ...

Graphene pushes the speed limit of light-to-electricity conversion

The efficient conversion of light into electricity plays a crucial role in many technologies, ranging from cameras to solar cells. It also forms an essential step in data communication applications, since it allows for information ...

Engineers efficiently 'mix' light at the nanoscale

The race to make computer components smaller and faster and use less power is pushing the limits of the properties of electrons in a material. Photonic systems could eventually replace electronic ones, but the fundamentals ...
