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 ...
Manipulating magnetic field effects in organic semiconductors
Changing the polarity of the magnetic field response of a material one thousandth the width of a human hair may seem like the stuff of science fiction, but that's exactly what's happening at NIST.
Can magnetically levitating trains run at 3,000km/h?
Trains that use magnets to levitate above the tracks might sound like something from Back to the Future, but the concept of magnetic levitation has been around for many years. Maglev trains, which use this ...
Speeding up data storage by a thousand times with 'spin current'
The storage capacity of hard drives is increasing explosively, but the speed with which all that data can be written has reached its limits. Researchers at Eindhoven University of Technology and the FOM Foundation ...
MESSENGER and STEREO measurements open new window into high-energy processes on the Sun
Understanding the sun from afar isn't easy. How do you figure out what powers solar flares – the intense bursts of radiation coming from the release of magnetic energy associated with sunspots – when ...
