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.....»»
An electrical change of phase using skyrmions
In a discovery that could have important implications for low-power computer memory, RIKEN researchers have shown that an entire sample can be switched between different magnetic states, or phases, simply by applying an electrical current......»»

Metomic has raised a $20 million Series A funding round. The round is led by Evolution Equity Partners with participation from Resonance and Connect Ventures. The investment will be used for U.S. expansion efforts and research and development initiat.....»»
Single gene causes stinging cell to lose its sting
When scientists disabled a single regulatory gene in a species of sea anemone, a stinging cell that shoots a venomous miniature harpoon for hunting and self-defense shifted to shoot a sticky thread that entangles prey instead, according to a new stud.....»»
Tested: Anker’s new 3-in-1 Charging Cube delivers its first 15W MagSafe experience
Anker is finally out with a 15W MagSafe charger, packing Apple’s full magnetic charging spec into a compact design. The new MagSafe 3-in-1 Cube delivers more than just the ideal iPhone 14 companion, with a fold up stand that reveals spot for AirPo.....»»
Novel quantum detection method for in-situ sensitive magnetic measurement under high pressure
Substances exhibit many novel properties under high pressure, for example, pressure can induce insulator-metal or even superconductor transitions. However, in-situ magnetic measurement is always a difficult problem in high pressure research and restr.....»»
Physicists make most precise measurement yet of magnetic moment of an electron
A combined team of physicists from Harvard University and Northwestern University has found the most precise value yet for the magnetic moment of an electron. In their paper published in the journal Physical Review Letters, the group describes the me.....»»
Frustrated ferromagnetic transition in AB-stacked honeycomb bilayer
In two-dimensional (2D) ferromagnets, anisotropy is essential for the magnetic ordering as dictated by the Mermin-Wagner theorem. The recently discovered van der Waals ferromagnets are largely considered to have uniaxial anisotropy. On the other hand.....»»
Polarized shockwaves shake the universe"s cosmic web
ICRAR researchers have discovered tantalizing evidence of magnetic fields in the universe's largest cosmic structures......»»
Study investigates magnetic field of an extremely ultraluminous X-ray pulsar
Using NASA's Swift spacecraft and ESA's XMM-Newton satellite, astronomers have observed NGC 5907 ULX1—the most luminous ultra-luminous X-ray pulsar known to date. Results of the observational campaign, published February 7 on the pre-print server a.....»»
Diamond-based power semiconductors may be available in 2030
Diamond-based power semiconductors are likely to hit the market as early as 2030 thanks to new development achievements in Japan in the past two years, although it is believed that diamond as the ultimate semiconductor won't be popularized until 2040.....»»
Chiral phonons create spin current without needing magnetic materials
Researchers from North Carolina State University and the University of North Carolina at Chapel Hill used chiral phonons to convert wasted heat into spin information—without needing magnetic materials. The finding could lead to new classes of less.....»»
Tested: elago’s Magnetic iPad Stand elevates your workstation with an iMac-inspired design
Lately across 9to5 we’ve been boasting about just how good of an experience Apple’s latest iPads make as a full-fledged computer. To help in elevating iPadOS from just a glorified mobile operating system, today we’re taking a look at the new M.....»»
Deposit insurance and depositor behavior: Evidence from Colombia
One of the feats that earned Douglas Diamond and Philip Dybvig the 2022 Nobel Prize in Economics (joint with Ben Bernanke) is a model of bank runs and related financial crises. In an article published in 1983, they noted that, in 1930s America, peopl.....»»
Explanation found for puzzling observation of Shiba states in superconductors
The origin of a mysterious experimental observation in a superconductor with a magnetic impurity sitting on top of it has been revealed in a theoretical study by a RIKEN researcher and a collaborator. This could help realize a robust quantum state re.....»»
Scientists propose novel NO2 sensor based on static magnetic field Faraday rotation spectroscopy
A low-power Faraday rotation spectroscopy (FRS) nitrogen dioxide (NO2) sensor basing on ring array permanent magnets was proposed by researchers led by Prof. Gao Xiaoming from the Hefei Institutes of Physical Science of the Chinese Academy of Science.....»»
Two spacecraft worked together to learn about Venus’ magnetic field
A pair of spacecraft happened to be passing by Venus on their way somewhere else, but they managed to grab some bonus data about the planet......»»
One of James Webb’s four instruments is offline following error
The James Webb Space Telescope is experiencing an issue with one of its instruments, the Near Infrared Imager and Slitless Spectrograph or NIRISS......»»
Instrument on JWST has gone offline
The JWST is having a problem. One of its instruments, the Near Infrared Imager and Slitless Spectrograph (NIRISS), has gone offline. The NIRISS performs spectroscopy on exoplanet atmospheres, among other things......»»
BepiColombo and Solar Orbiter compare notes at Venus
The convergence of two spacecraft at Venus in August 2021 has given a unique insight into how the planet is able to retain its thick atmosphere without the protection of a global magnetic field......»»
