Magnetic memory states go exponential

Posted by in categories: computing, nanotechnology, particle physics

In a new study, a group of researchers led by Prof. Lior Klein, from the physics department and the Institute of Nanotechnology and Advanced Materials at Bar-Ilan University, has shown that relatively simple structures can support an exponential number of magnetic states—much greater than previously thought. They have additionally demonstrated switching between the states by generating spin currents. Their results may pave the way to multi-level magnetic memory with an extremely large number of states per cell; it could also have application in the development of neuromorphic computing, and more. Their research appears as a featured article on the cover of a June issue of Applied Physics Letters.

Spintronics is a thriving branch of nano-electronics which uses the spin of the electron and its associated in addition to the electron charge used in traditional electronics. The main practical contributions of spintronics are in magnetic sensing and non-volatile magnetic data storage, and researchers are pursuing breakthroughs in developing magnetic-based processing and novel types of .

Spintronics devices commonly consist of magnetic elements manipulated by spin-polarized currents between stable magnetic states. When spintronic devices are used for storing data, the number of stable states sets an upper limit on capacity. While current commercial magnetic memory cells have two stable magnetic states corresponding to two memory states, there are clear advantages to increasing this number, as it will potentially allow increasing memory density and enable the design of novel types of memory.

St. George-based inventor goes public with ZHeus 3, a weapon with big implications for police reform

Posted by in categories: military, weapons

ST. GEORGE — An invention that could lead to the end of gunpowder is not just an idea — it’s already been used in a real-world military mission.

Priced at $1 million, ZHeus 3 is not a gun; it’s a “platform” that has taken Harvester, a St. George-based inventor, 15 years to design. Harvester could not release his full name because he still has a commitment to national security.

The idea for this invention, along with an improved armor, began some 15 years ago when Harvester’s best friend died in his arms after being shot during an Air Force mission. The bullet shot straight through his friend’s bulletproof vest and kept going.

MIT’s New Diamond-Based Quantum Chip Is the Largest Yet

Posted by in categories: computing, particle physics, quantum physics

Researchers at MIT have developed a process to manufacture and integrate “artificial atoms” with photonic circuitry, and in doing so, are able to produce the largest quantum chip of its kind.

The atoms, which are created by atomic-scale defects in microscopically thin slices of diamond, allow for the scaling up of quantum chip production.

The F-16’s Replacement Won’t Have a Pilot at All

Posted by in categories: drones, military, robotics/AI, space

Innovation.


The U.S. Air Force plans to have an operational combat drone by 2023. The service plans to build out a family of unmanned aircraft, known as Skyborg, capable of carrying weapons and actively participating in combat. The Air Force’s goal is to build up a large fleet of armed, sort-of disposable jets that don’t need conventional runways to take off and land.

A Stem Cell Transplant Has Cured Two HIV Patients

Posted by in category: biotech/medical

Human immunodeficiency virus (HIV) has been traced as far back as a century ago, but it wasn’t identified until the 1980s, when it captured public attention for causing a sweeping wave of deaths.

About 32 million people have died from HIV and AIDS, which is the term for the range of conditions caused by the virus. A cure for HIV has so far been elusive, but hope has flickered anew because two people who received a stem cell transplant are now clear of the disease. Hope, though, can be held with only great reservation because of beliefs in previous efforts for a cure that failed. Not to mention, stem cell transplants are risky for those who don’t have cancer.

Still, any bit of hope for an end to HIV means that work for a cure continues apace, giving the nearly 38 million people living with the disease something to hold onto.
