On-chip topological light: First measurements of transmission and delay
Topological transport of light is the photonic analog of topological electron flow in certain semiconductors. In the electron case, the current flows around the edge of the material but not through the bulk. ...
A two-stage trap for single protons leads to measurement of their magnetic properties
Detailed knowledge of the physical properties of the building blocks of matter is fundamental to our understanding of the Universe. These building blocks include the protons, neutrons and electrons that make ...
Researchers develop treated surfaces that can actively control how fluids or particles move (w/ Video)
Researchers at MIT and in Saudi Arabia have developed a new way of making surfaces that can actively control how fluids or particles move across them. The work might enable new kinds of biomedical or microfluidic ...
Tiny magnets, huge fields: Nanoscale ferromagnetic electrodes create chemical equivalent of solid-state spin valve
Charging electric cars efficiently inductive
We already charge our toothbrushes and cellphones using contactless technology. Researchers have developed a particularly efficient and cost-effective method that means electric cars could soon follow suit.
Mercury's magnetic field tells scientists how its interior is different from Earth's
Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report.
Seeing is bead-lieving: Scientists create model 'bead-spring' chains with tunable properties
Rice University researchers are using magnetic beads and DNA "springs" to create chains of varying flexibility that can be used as microscale models for polymer macromolecules.
Measuring the smallest magnets: Physicists measured magnetic interactions between single electrons
Imagine trying to measure a tennis ball that bounces wildly, every time to a distance a million times its own size. The bouncing obviously creates enormous "background noise" that interferes with the measurement. ...
New theory predicts magnets may act as wireless cooling agents.
The magnets cluttering the face of your refrigerator may one day be used as cooling agents, according to a new theory formulated by MIT researchers.
Voyager spacecraft might not have reached interstellar space
In 2012, the Voyager mission team announced that the Voyager 1 spacecraft had passed into interstellar space, traveling further from Earth than any other manmade object.
Fermi finds a 'transformer' pulsar
(Phys.org) —In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at ...
Suddenly, the sun is eerily quiet: Where did the sunspots go?
The sun has gone quiet. Almost too quiet. A few weeks ago it was teeming with sunspots, as you would expect since we are supposed to be in the middle of solar maximum-the time in the sun's 11-year cycle when ...
A stunning image of our home star
Active regions 2108 and 2109 are now passing around the limb of the Sun, but not before solar photography specialist Alan Friedman grabbed a few pictures of them on Friday! The image above, captured by ...
Solar storm radiation can be harmful for frequent fliers
Space weather impacts many modern-day technologies. But one of the most concerning – and least reported – space weather effects is the increased radiation exposure to passengers on commercial long-distance ...
