MRI for a quantum simulation
Magnetic resonance imaging (MRI), which is the medical application of nuclear magnetic resonance spectroscopy, is a powerful diagnostic tool. MRI works by resonantly exciting hydrogen atoms and measuring ...
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.
Spin-based electronics: New material successfully tested
Spintronics is an emerging field of electronics, where devices work by manipulating the spin of electrons rather than the current generated by their motion. This field can offer significant advantages to computer technology. ...
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 ...
How to better allocate research money and fix a flawed system
Taxpayers want to know that their money is well spent on research. Yet funding agencies persist in trying to explain research results in terms of papers and publications rather than in terms of people – ...
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 ...
Working group explores the 'frustration' of spin glasses
Spin glasses are frustrating. Although the ideas have been around for decades and form the foundation of countless complex systems models, they have nonetheless resisted researchers' efforts to understand exactly how they ...
Self-assembling nanoparticle could improve MRI scanning for cancer diagnosis
Scientists have designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier.
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 ...
