Lens-Free Microscope Detects Cancer at Cell Level

Lens-Free Microscope Detects Cancer at Cell Level

UCLA researchers have developed a lens-free microscope that can be used to detect the presence of cancer or other cell-level abnormalities with the same accuracy as larger and more expensive optical microscopes.   The invention could lead to less expensive and more portable technology for performing common examinations of tissue, blood and other biomedical specimens. [...]

Scientists Measure Speedy Electrons in Silicon

Scientists Measure Speedy Electrons in Silicon

The entire semiconductor industry, not to mention Silicon Valley, is built on the propensity of electrons in silicon to get kicked out of their atomic shells and become free. These mobile electrons are routed and switched though transistors, carrying the digital information that characterizes our age.   An international team of physicists and chemists based [...]

Breakthrough in Flexible Electronics

Breakthrough in Flexible Electronics

A research team led by Prof. Keon Jae Lee of KAIST provides an easier methodology to realize high performance flexible electronics by using the Inorganic-based Laser Lift-off (ILLO), which enables nanoscale processes for high density flexible devices and high temperature processes that were previously difficult to achieve on plastic substrates.   Flexible electronics have been [...]

New Technique for Generating Electricity

New Technique for Generating Electricity

Research scientists at VTT Technical Research Centre of Finland have demonstrated a new technique for generating electrical energy. The new method can be used in harvesting energy from mechanical vibrations of the environment and converting it into electricity. Energy harvesters are needed, for example, in wireless self-powered sensors and medical implants, where they could ultimately [...]

Circuits That Melt Away When You’re Done

Circuits That Melt Away When You’re Done

Electronic devices that dissolve completely in water, leaving behind only harmless end products, are part of a rapidly emerging class of technology pioneered by researchers at the University of Illinois at Urbana-Champaign. Early results demonstrate the entire complement of building blocks for integrated circuits, along with various sensors and actuators with relevance to clinical medicine, [...]

Talking to Your Car Is Often Distracting

Talking to Your Car Is Often Distracting

Two new AAA-University of Utah studies show that despite public belief to the contrary, hands-free, voice-controlled automobile infotainment systems can distract drivers, although it is possible to design them to be safer.   “Even though your car may be configured to support social media, texting and phone calls, it doesn’t mean it is safe to [...]

Physicist Turns Smartphones Into Pocket Cosmic Ray Detectors

Physicist Turns Smartphones Into Pocket Cosmic Ray Detectors

Soon, the growing capability of your smartphone could be harnessed to detect cosmic rays in much the same way as high-end, multimillion-dollar observatories.   With a simple app addition, Android phones, and likely other smartphone brands in the not-too-distant future, can be turned into detectors to capture the light particles created when cosmic rays crash [...]
