Like the flutter of a butterfly’s wings, sometimes small and minute changes can lead to big and unexpected results and changes in our lives. Recently, a team of researchers at Pohang University of Science and Technology (POSTECH) made a very small change to develop a material called “spin-orbit torque (SOT),” which is a hot topic in next-generation DRAM memory.

This research team, led by Professor Daesu Lee and Yongjoo Jo, a PhD candidate, from the Department of Physics and Professor Si-Young Choi from the Department of Materials Science and Engineering at POSTECH, achieved highly efficient field-free (i.e. SOT magnetization switching that does not require the assistance of a magnetic field) SOT magnetization switching through atom-level control of composite oxides.

Their findings were recently published in Nano Letters (“Field-Free Spin–Orbit Torque Magnetization Switching in a Single-Phase Ferromagnetic and Spin Hall Oxide”).

Make it so.

Brazilian physicist César Lattes, considered a national hero for his discoveries, paved the way for trailblazing research projects in particle astrophysics across Latin America and beyond.

The legendary electrical engineer held 112 U.S. patents. The post It’s Nikola Tesla’s birthday – here’s why that name sounds so familiar appeared first on MotorBiscuit.

Engineers at EPFL have developed a device capable of transforming heat into electrical voltage efficiently at temperatures even colder than those found in outer space. This breakthrough could significantly advance quantum computing technologies by addressing a major obstacle.

To perform quantum computations, quantum bits (qubits) need to be cooled to temperatures in the millikelvin range (close to-273 degrees Celsius) to reduce atomic motion and minimize noise. However, the electronics used to control these quantum circuits generate heat, which is challenging to dissipate at such low temperatures. Consequently, most current technologies must separate the quantum circuits from their electronic components, resulting in noise and inefficiencies that impede the development of larger quantum systems beyond the laboratory.

Researchers in EPFL’s Laboratory of Nanoscale Electronics and Structures (LANES), led by Andras Kis, in the School of Engineering have now fabricated a device that not only operates at extremely low temperatures, but does so with efficiency comparable to current technologies at room temperature.

Webb’s image of RX J1131-1231 uses gravitational lensing to explore the quasar ’s black hole and dark matter, revealing details about its growth and the universe’s mass composition.

This new James Webb Space Telescope image features the gravitational lensing of the quasar known as RX J1131-1231, located roughly six billion light-years from Earth in the constellation Crater. It is considered one of the best-lensed quasars discovered to date, as the foreground galaxy smears the image of the background quasar into a bright arc and creates four images of the object.

A global research team has devised a method to decompose plastics and other materials into their smallest components using a laser, enabling their future reuse.

The breakthrough involves placing these materials on two-dimensional structures called transition metal dichalcogenides and then exposing them to laser light. This technique could significantly enhance the disposal of plastics that are currently almost impossible to break down with existing technologies.

Why did the experience of consciousness evolve from our underlying brain physiology? Despite being a vibrant area of neuroscience, current research on consciousness is characterised by disagreement and controversy – with several rival theories in contention.

A recent scoping review of over 1,000 articles identified over 20 different theoretical accounts. Philosophers like David Chalmers argue that no single scientific theory can truly explain consciousness.

We define consciousness as embodied subjective awareness, including self awareness. In a recent article published in Interalia (which is not peer reviewed), we argue that one reason for this predicament is the powerful role played by intuition.
