Chinese Business Owner Admits Smuggling Nvidia High-End Chips; Deepseek Core Member Worked at Nvidia

The person in the video is Su Ji, the founder of Garage Café. After struggling to keep his business afloat, he turned to smuggling high-tech products from the US and created a platform called Kunlun Nest. In another video, Su Ji continued to boast about smuggling, explaining how he bypassed US sanctions to acquire 200 NVIDIA H200 graphics cards.

Study demonstrates phase-tunable spin-wave-mediated mutual synchronization of spin Hall nano-oscillators

Spin Hall nano-oscillators (SHNOs) are nanoscale spintronic devices that convert direct current into high-frequency microwave signals through spin wave auto-oscillations. This is a type of nonlinear magnetization oscillations that are self-sustained without the need for a periodic external force.

Theoretical and simulation studies found that propagating spin-wave modes, in which spin waves move across materials instead of being confined to the auto-oscillation region, can promote the coupling between SHNOs.

This coupling may in turn be harnessed to adjust the timing of oscillations in these devices, which could be advantageous for the development of neuromorphic computing systems and other spintronic devices.

The Quantum Twist: Scientists Unlock a New Way to Control Electrons

Electrons have a hidden feature — spin — that could revolutionize technology. Magnets can control it, but researchers are now exploring chiral molecules as an alternative. These uniquely shaped molecules might help direct electron spin just as well, opening new possibilities for future electronics.

Electrons are well known for their negative charge, which plays a key role in electric currents. However, they also possess another important property: spin, or magnetic moment. This characteristic has significant potential for improving data storage technologies, but controlling electron spin has proven challenging.

Specifically, isolating electrons with a particular spin direction, such as spin-up, is difficult. One established method involves passing an electric current through a ferromagnetic material, like iron. This process aligns the spin polarization of the electrons with the material’s magnetic field.

Forget Silicon — DNA Might Be the Future of Quantum Computing

Researchers have uncovered a way to manipulate DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

From desktop to benchtop with automated computational workflows for computer-aided design in asymmetric catalysis

Computational chemistry has remained largely inaccessible to the experimental chemistry community. Here we report the VIRTUAL CHEMIST, a software suite free for academic use, that enables organic chemists without expertise in computational chemistry to perform virtual screening experiments for asymmetric catalyst discovery and design.
