A step closer to composite-based electronics
Composite materials are of increasing interest to physicists. Typically, they are made of electrically conducting elements - such as spherical metallic or elongated carbon particles - embedded in an insulating ...
Physics shows how the mushroom spews its spores
Plants use a variety of methods to spread their seeds, including gravity, forceful ejection, and wind, water, and animal dispersion. But what of the mushrooms, whose spores also need to be strewn far and ...
Ultra-sensitive force sensing with a levitating nanoparticle
A recent study led by researchers of the Institute of Photonic Sciences (ICFO) achieved the highest force sensitivity ever observed with a nano-mechanical resonator. The scientific results of this study have ...
How a leftover Thanksgiving dinner gave us LASIK surgery
It was the day after Thanksgiving in 1981, and like most others across the nation, Rangaswamy "Sri" Srinivasan, a researcher at IBM's Thomas J. Watson Research Center in New York, had brought some turkey ...
A new, flying jellyfish-like machine (w/ Video)
Up, up in the sky: It's a bird! It's a plane! It's a... jellyfish? That's what researchers have built—a small vehicle whose flying motion resembles the movements of those boneless, pulsating, water-dwelling creatures.
Diamond 'flaws' pave way for nanoscale MRI
Breakthrough offers high-sensitivity nanoscale sensors, and could lead to magnetic imaging of neuron activity and thermometry on a single living cell.
X-rays reveal another feature of high-temperature superconductivity
Classical and high-temperature superconductors differ hugely in the value of the critical temperatures at which they lose all electrical resistance. Scientists have now used powerful X-rays to establish another ...
Novel X-ray device developed
Using a compact but powerful laser, a research team at the University of Nebraska-Lincoln has developed a new way to generate synchrotron X-rays.
How losing information can benefit quantum computing
Suggesting that quantum computers might benefit from losing some data, physicists at the National Institute of Standards and Technology (NIST) have entangled—linked the quantum properties of—two ions ...
Scientists prove X-ray laser can solve protein structures from scratch
A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
Great lakes waterfowl die-offs: Finding the source
A deadly menace stalks the loons, gulls and other water birds of the Great Lakes region: Type E botulism, a neuromuscular disease caused when birds eat fish infected with toxin-producing bacteria. Cases of ...
The physics of beer tapping
An old, hilarious if somewhat juvenile party trick involves covertly tapping the top of someone's newly opened beer bottle and then standing back as the suds foam out onto the floor.
The secrets of owls' near noiseless wings
Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings – allowing them to hunt and capture their prey in silence.
New microscope captures movements of atoms and molecules
A new microscope invented at Michigan State University allows scientists to zoom in on the movements of atoms and molecules.
