Researchers devise a way to mimic gravitational lensing in a way that can be seen
Bright, laser-based lighting devices
As a modern culture, we crave artificial white lights—the brighter the better, and ideally using less energy than ever before. To meet the ever-escalating demand for more lighting in more places and to ...
Scientists rig hospital-grade lightweight blood flow imager on the cheap
Tracking blood flow in the laboratory is an important tool for studying ailments like migraines or strokes and designing new ways to address them. Blood flow is also routinely measured in the clinic, and ...
Scientists create never-before-seen form of matter
Harvard and MIT scientists are challenging the conventional wisdom about light, and they didn't need to go to a galaxy far, far away to do it.
First real-time detector for IV delivered drugs may help eliminate life-threatening medical errors
Today, computerized smart systems can deliver drugs intravenously in exact volumes to hospital patients. However, these systems cannot recognize which medications are in the tubing nor can they determine ...
SLAC scientists create twisted light
(Phys.org) —Scientists at SLAC have found a new method to create coherent beams of twisted light – light that spirals around a central axis as it travels. It has the potential to generate twisted light ...
Researchers' smartphone 'microscope' can detect a single virus, nanoparticles
(Phys.org) —Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair.
Fastest rotating man-made object created
(Phys.org) —A team of researchers at the University of St Andrews has created the world's fastest spinning man-made object.
Ultra-high-speed nanomaterial synthesis process developed using laser beams
Dr. Jun Yeop, Yeo and the research team led by Professor Seung Hwan, Ko (both of the Department of Mechanical Engineering at KAIST) successfully developed a process enabling the location-determinable, ultra high speed synthesis ...
NIST ytterbium atomic clocks set record for stability
A pair of experimental atomic clocks based on ytterbium atoms at the National Institute of Standards and Technology (NIST) has set a new record for stability. The clocks act like 21st-century pendulums or ...
'Groovy' hologram creates strange state of light at visible and invisible wavelengths
(Phys.org) —Applied physicists at the Harvard School of Engineering and Applied Sciences (SEAS) have demonstrated that they can change the intensity, phase, and polarization of light rays using a hologram-like ...
Mobius strip ties liquid crystal in knots to produce tomorrow's materials and photonic devices
University of Warwick scientists have shown how to tie knots in liquid crystals using a miniature Möbius strip made from silica particles.
One-of-a-kind spectrometer reads vibrations between atoms to find structures of molecules
A Rice University laboratory has improved upon its ability to determine molecular structures in three dimensions in ways that challenge long-used standards.
Researchers use nanoparticles to fight cancer
Researchers at the University of Georgia are developing a new treatment technique that uses nanoparticles to reprogram immune cells so they are able to recognize and attack cancer. The findings were published ...
