Ultra-high-speed optical communications link sets new power efficiency record
Ultrafast supercomputers that operate at speeds 100 times faster than current systems are now one step closer to reality. A team of IBM researchers working on a U.S. Defense Advanced Research Projects Agency ...
Ex nihilo: Dynamical Casimir effect in metamaterial converts vacuum fluctuations into real photons
Light-emitting bioprobe fits in a single cell
If engineers at Stanford have their way, biological research may soon be transformed by a new class of light-emitting probes small enough to be injected into individual cells without harm to the host. Welcome ...
Gap geometry grasped: New algorithm could help understand structure of liquids, how they flow through porous media
Theoretical physicist Moumita Maiti and colleagues at the Jawaharlal Nehru Centre for Advanced Scientific Research in Bangalore, India, have now implemented an algorithm for analysing void space in sphere ...
Real angry birds 'flip the bird' before a fight
Male sparrows are capable of fighting to the death. But a new study shows that they often wave their wings wildly first in an attempt to avoid a dangerous brawl.
New study reveals contribution of little known Austrian physicist, Friedrich Hasenöhrl, to famous Einstein equation
Two American physicists outline the role played by Austrian physicist Friedrich Hasenöhrl in establishing the proportionality between the energy (E) of a quantity of matter with its mass (m) in a cavity filled with radiation. ...
Research team discovers third type of volcanic eruption
Chemistry resolves toxic concerns about carbon nanotubes
Safety fears about carbon nanotubes, due to their structural similarity to asbestos, have been alleviated following research showing that reducing their length removes their toxic properties.
New insights into mosquitoes' role as involuntary bioterrorists
For many years scientists thought that mosquitoes provided the disease organisms which they spread with a relatively free ride because the insects didn't have much in the way of natural defenses to fight ...
New technology to revolutionise controlled ripening of fruit
(Phys.org)—Materials scientists from The University of Queensland (UQ) are set to revolutionise the fresh fruit industry with a new technology that converts gases into a powder form.
Size matters when reducing NiO nanoparticles
(Phys.org)—New research finds that size plays a major role in how nanoscale nickel oxide (NiO) shells behave when being reduced to solid nickel nanoparticles.
How does a volcanic crater grow? Grab some TNT and find out (w/ video)
A new University at Buffalo study in the journal Geophysical Research Letters examines maar craters, which resemble the bowl-like cavities formed by meteorites but are in some ways more mysterious.
Could insulin-loaded nasal gel mean the end of injections for diabetics?
(Phys.org)—Scientists have developed a once-a-day nasal gel formulation for the delivery of insulin that could put an end to injections for Type 1 diabetes sufferers.
