Miniature magnetic resonance imager made of diamond
The development of tumors begins with miniscule changes within the body's cells; ion diffusion at the smallest scales is decisive in the performance of batteries. Until now, the resolution of conventional imaging methods has not been high enough to r.....»»
Belkin Wireless Magnetic Charging Stand review: Minimalistic, gets the job done
Great MagSafe compatible accessories can be attached to a high price tag. Belkin, who has produced several MagSafe-compatible accessories, may have broken the stereotype with the affordable Wireless Magnetic Charging Stand.Usually, for charging stand.....»»
Researchers find potential mechanism of solar light bridge formation and penumbra disappearance
Sunspots are the most noticeable manifestation of solar magnetic field concentrations in the photosphere. A typical mature sunspot has an umbra and a penumbra. Light bridges (LBs) are the strip-like bright features, two ends of which connect the penu.....»»
Definite spectroscopic evidence for magnetic reconnection in splitting of solar filament structure
Magnetic reconnection is a universal process that changes magnetic topology and converts magnetic energy to plasma kinetic energy. Spatially resolved spectroscopic observations covering extended regions in the solar atmosphere are rare, and thus the.....»»
WaterField"s Magnetic Laptop Sleeve now fits MacBook Pro
WaterField Designs has released its Magnetic Laptop Sleeve in new sizes that can fit a 14-inch or 16-inch MacBook Pro.Magnetic Laptop SleeveThe company uses high-quality sleeve materials, including waxed canvas, full-grain leather, shock-absorbing ne.....»»
The mechanism of cosmic magnetic fields explored in the laboratory
Plasma is matter that is so hot that the electrons are separated from atoms. The electrons float freely and the atoms become ions. This creates an ionized gas—plasma—that makes up nearly all of the visible universe. Recent research shows that mag.....»»
New optical method to verify topological phases in magnetic materials
Topological phases are not restricted to electronic systems. They can also occur in magnetic materials whose properties are described in terms of magnetic waves—or so-called magnons. However, even though scientists have established techniques to ge.....»»
Hands-on: This magnetic stand gives your iPad a Pro Display XDR-like design
Apple accessory company, ChargenPro, recently announced pre-orders for their new MagFlött Pro Stand for iPad Pro. They hit the scene last year with their patented which touted a simple, yet elegant way of propping up an iPad on a magnetic stand......»»
Migrating birds: Disturbances in magnetic field suspected when birds go astray
It seems logical enough that bad weather can sometimes cause birds to become disoriented during their annual fall migrations—causing them to wind up in territory they're unaccustomed to. But why, even when weather is not a major factor, do birds tr.....»»
Astronomers create new microwave map of the Milky Way and beyond
An international team of scientists have successfully mapped the magnetic field of our galaxy, the Milky Way, using telescopes that observe the sky in the microwave range. The new research is published in Monthly Notices of the Royal Astronomical Soc.....»»
The US Just Greenlit High-Tech Alternatives to Animal Testing
Lab animals have long borne the brunt of drug safety trials. A new law allows drugmakers to use miniature tissue models, or organs-on-chips, instead......»»
Cosmic superbubble"s magnetic field charted in 3D for the first time
Astronomers at the Center for Astrophysics | Harvard & Smithsonian (CfA) have unveiled a first-of-its-kind map that could help answer decades-old questions about the origins of stars and the influences of magnetic fields in the cosmos......»»
Electrons take new shape inside unconventional metal
One of the biggest achievements of quantum physics was recasting our vision of the atom. Out was the early 1900s model of a solar system in miniature, in which electrons looped around a solid nucleus. Instead, quantum physics showed that electrons li.....»»
"Superdeep" diamond deepens our understanding of plate tectonics
A unique combination of minerals trapped inside a "superdeep" diamond that originated hundreds of kilometers beneath Earth's surface sheds new light on plate tectonics, the geological processes that give rise to mountains, oceans and continents......»»
Scientists find evidence for magnetic reconnection between Ganymede and Jupiter
In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team led by Southwest Research Institute used Juno data to examine the electron and ion particles and magnetic fields.....»»
Cooling 100 million degree plasma with a hydrogen-neon mixture ice pellet
At ITER—the world's largest experimental fusion reactor, currently under construction in France through international cooperation—the abrupt termination of magnetic confinement of a high temperature plasma through a so-called "disruption" poses a.....»»
Decoding mega magnetic explosions outside the solar system
Neutron stars and black holes may be stellar corpses, but they are among the most active celestial objects. They produce some of the highest-energy radiation ever observed, and scientists have long puzzled over the physics that underlies the process.....»»
Active terahertz beam steering based on mechanical deformation of a liquid crystal elastomer metasurface
Traditionally, active metasurface research has primarily focused on changing the dielectric constant and permeability of the substrate, which frequently results in resonance effect and ohmic loss. However, a reconfigurable metasurface based on mechan.....»»
Moon water imager integrated with NASA"s Lunar Trailblazer
Lunar Trailblazer, NASA's mission led by Caltech in Pasadena, California to understand lunar water and the moon's water cycle, is one step closer to launching next year. Earlier this month, the agency's Jet Propulsion Laboratory in Southern Californi.....»»
Researchers discover "dormant" magnetosome genes in non-magnetic bacteria
Magnetic bacteria can align their movement with the Earth's magnetic field thanks to chains of magnetic nanoparticles inside their cells. The blueprints for making and linking these magnetosomes are stored in the bacteria's genes......»»
Rapid test based on specially designed magnetic nanoparticles reliably detects pathogens in a few seconds
The current rapid tests for diagnosing infectious diseases are speedy, but not really fast. For example, antigen self-tests, PCR tests or ELISA tests for coronavirus take 15 minutes to several hours before a reliable result is available......»»
