CMOS Imaging sensors are the sensor of choice for most consumer digital cameras. They tend to be cheap, low power, compatible with the fabrication equipment that much of modern digital electronics is…

We've done articles on rainbows, and double rainbows and even showed you how to make a rainbow appear for that special someone - but have you ever seen a triple rainbow? Scientific reports of…

Optofluidic solar lighting systems could mean a real boost in solar energy - they capture sunlight from a roof using a light concentrating system that follows the sun's path by changing the angle of…

New nano-structured glass optical elements could significantly reduce the cost of medical imaging. In their Applied Physics Letters paper, the team describes how they have used nano-structures to…

What Color Is An Orange ? A question like that, here at science20.com, just has to be a trick question. It is possible, by the application of common sense arguments, to prove to a scientific level of…

One of the earliest lessons science students learn is that a beam of light travels in a straight line and fan out, or diffract, as they travel. Recently it was discovered that light rays can travel…

My wife and I once saw a rainbow and we discussed how it happened. She listened somewhat patiently for the first few sentences and then told me I was spoiling the magic of the rainbow, like it was…

The future of networking may mean streaming high-definition movies at blazing fast speeds and the routers are the lights in the room. Scientists at the Fraunhofer Institute for Telecommunications,…

Researchers from Cornell say that by using a bit of electromagnetics wizardry they can create a 'hole' in space and keep it hidden - spatial cloaking.   Invisible time. We see things using light…

Researchers are reporting the construction of what they term "artificial molecules" and say they can use the technology to engineer a new generation of nanomaterials that control and direct the…
