Lost And Found At Magnetic Fields
I don’t consider myself a social butterfly, but more of an anti-social moth. In front of me now lay a Mount Doom-like task—to spend three days in the desert of Alsisar, attending the 2023 Magnetic Field Festival. Here, everyone was a stranger. Lost in my dilemma, I made two temporary best friends at the Jaipur
Magnetic plant biobots can be effectively used for pesticide and heavy metal removal
Schematic illustration of chlorpyrifos removal by propelled magnetic plant biobots (MPBs) under a transversal rotating magnetic field. Credit: NPG Asia Materials (2022). DOI: 10.1038/s41427-022-00425-0 Biohybrid micro/nanorobots that integrate biological entities with artificial nanomaterials have shown great potential in the field of biotechnology. However, commonly used physical hybridization approaches can lead to blockages and damage to
Magnetic reconnection breakthrough may help predict space weather
A West Virginia University postdoctoral researcher in the Department of Physics and Astronomy has made a breakthrough in the study of magnetic reconnection, which could prevent space storms from wreaking havoc on the Earth's satellite and power grid systems. Peiyun Shi's research is the first-of-its-kind in the laboratory setting and is part of the PHASMAproject,…
Skyrmions – Tiny Magnetic Swirls – Used To Generate True Random Numbers
Skyrmions, tiny magnetic anomalies that arise in two-dimensional materials, can be used to generate true random numbers useful in cryptography and probabilistic computing. Whether for use in cybersecurity, gaming, or scientific simulation, the world needs true random numbers, but generating them is harder than one might think. But a group of Brown University physicists has…
Magnetic surprise revealed in ‘magic-angle’ graphene
When two sheets of the carbon nanomaterial graphene are stacked together at a particular angle with respect to each other, it gives rise to some fascinating physics. For instance, when this so-called "magic-angle graphene" is cooled to near absolute zero, it suddenly becomes a superconductor, meaning it conducts electricity with zero resistance. Now, a research…
Inhibitory brain stimulation allows better memorization by reducing the power of beta-waves in the brain. Memories of past events and experiences are what define us as who we are, and yet the ability to form these episodic memories declines with age, certain dementias, and brain injury. However, a study publishing in the open access journal PLOS…
