Integrated spin wave storage advances quantum networks

The University of Science and Technology of China has achieved a significant milestone in quantum memory research, addressing a long-standing challenge in integrated solid-state devices. The team, led by Chuan-Feng Li and Zong-Quan Zhou, has demonstrated an integrated spin-wave quantum memory capable of extended storage times and on-demand retrieval. This development marks a critical step toward scalable quantum networks.

Quantum memories play a pivotal role in enabling long-distance entanglement by linking short-distance connections, overcoming photon transmission losses. Rare-earth ions doped crystals have emerged as promising systems for quantum memory, with integrated solid-state devices showing particular potential. However, prior implementations were limited to optically excited states, which inherently restrict storage time and retrieval flexibility due to the short lifetime of these states.

The breakthrough lies in the implementation of spin-wave storage. This approach encodes photons into spin-wave excitations in ground states, vastly extending storage times to the spin coherence lifetime and enabling on-demand retrieval. Nevertheless, the challenge of separating single-photon signals from noise caused by strong control pulses has hindered progress in integrated structures — until now.

One Step Closer to a Cure: Breakthrough “Harmine Pill” Sparks Hope for 500 Million Diabetics Worldwide

Mount Sinai researchers discovered that harmine, a beta cell regenerative drug, may transform alpha cells into beta cells, offering scalable diabetes treatment options for millions.

Researchers and bioinformaticians at the Icahn School of Medicine at Mount Sinai have unveiled new insights into the mechanisms behind human beta cell regenerative drugs, offering a potential breakthrough for the over 500 million people worldwide living with diabetes. These findings, recently published in Cell Reports Medicine, could mark a significant step forward in diabetes treatment.

Diabetes occurs when pancreatic beta cells lose their ability to produce insulin, a hormone critical for maintaining healthy blood sugar levels. Despite significant advancements, there are still no widely scalable therapeutic solutions capable of addressing the global diabetes crisis.

Stanford’s Vaccine Breakthrough Boosts Flu Protection Like Never Before

Stanford Medicine researchers have developed a new method for influenza vaccination that encourages a robust immune response to all four common flu subtypes, potentially increasing the vaccine’s efficacy.

In laboratory tests using human tonsil organoids, the modified vaccine showed promising results in combating both seasonal and bird flu strains. The approach involves a combined antigen methodology that might also protect against emerging flu variants with pandemic potential.

Breakthrough in Pain Relief: Scientists Unveil a Safer, Non-Addictive Approach

NUS researchers found that deuterated water (D₂O) reduces pain by modulating the TRPV1 ion channel, offering a non-addictive alternative to conventional painkillers.

Researchers from the National University of Singapore (NUS), in partnership with Peking University, China, have uncovered new insights into the TRPV1 (transient receptor potential vanilloid 1) ion channel and its role in pain perception. Their findings demonstrate how solvent molecules can influence pain signals, paving the way for potential development of safer, non-addictive pain management strategies.

Effective pain management is vital for improving quality of life and overall well-being. The TRPV1 ion channel, which plays a key role in detecting pain, expands its pore when activated, enabling ions and larger molecules to pass through. However, the ability of water molecules to permeate the TRPV1 channel has remained uncertain.

Trillium sixth-generation TPU is in preview

The rise of generative AI has ushered in an era of unprecedented innovation, demanding increasingly complex and more powerful AI models. These advanced models necessitate high-performance infrastructure capable of efficiently scaling AI training, tuning, and inferencing workloads while optimizing for both system performance and cost effectiveness.

Google Cloud has been pioneering AI infrastructure for over a decade, culminating in a unified architecture called AI Hypercomputer that seamlessly integrates workload-optimized hardware (TPUs, GPUs, and CPUs), open software, and flexible consumption models to power the most advanced AI models. This holistic approach optimizes every layer of the stack for optimal scale, performance, and efficiency across the broadest range of models and applications. AI Hypercomputer is one of the many reasons why Google Cloud was named a leader in Forrester’s AI Infrastructure Wave. Just last week, Google Cloud was also named a Leader in Gartner’s Magic Quadrant for Strategic Cloud Platform Services, where for the second consecutive year, we are the only Leader to improve on both vision and ability to execute.

A new structure design enables a dual-function system for infrared camouflage and thermal management

Combining metallic glass with the Berreman mode of epsilon-near-zero (ENZ) thin films achieves a dual-function system for infrared camouflage and thermal management within an identical wavelength region of the atmospheric window. In recent research, metallic glasses were selected for their tunable optical properties, providing adjustable emissivity for versatile thermal camouflage while maintaining effective thermal management.

Thermal infrared camouflage aims to reduce the detectability of a target using thermal imaging devices. Given the typically high thermal emissivity in everyday environments, the thermal emissivity of the background environment must be considered. The conventional low-emissivity strategy for thermal camouflage is only effective for targets at extremely high temperatures, making it unsuitable for applications near room-to-medium-high temperature range (350 °C).

In a study published in Materials Horizons, Professor Hsuen-Li Chen from the Department of Materials Science and Engineering at National Taiwan University led his research team in designing an innovative multilayer thin-film structure. This structure introduces metallic glass into infrared thermal camouflage technology, exploiting its adjustable emissivity to accommodate diverse infrared thermal camouflage scenarios.

Scientists uncover insights into neuron function by simultaneously measuring two key signals in living animals

Researchers from Kyushu University have developed an innovative technique to non-invasively measure two key signals, membrane voltage and intracellular calcium levels, at the same time, in neurons of awake animals. This new method offers a more complete understanding of how neurons function, revealing that these two signals encode different information for sensory stimuli. The research was published in Communications Biology on September 16, 2024.

Neurons are cells that act as the brain’s fundamental building blocks, transmitting information through . When a neuron receives a stimulus, changes in membrane voltage (the electrical charge across the neuron cell membrane) trigger the neuron to activate, causing rapid changes in membrane voltage to propagate along the neuron as an electrical signal. These changes in membrane voltage then lead to changes in intracellular calcium (calcium levels inside neurons).

Historically, measuring membrane voltage has involved invasive techniques using electrodes. As a non-invasive alternative, scientists have developed techniques to measure calcium activity using fluorescent proteins that are sensitive to calcium ions as sensors, providing an indirect proxy for neuron activity. However, these different methods mean that the two signals have almost always been studied separately, making it challenging to understand how they interact in real-time and to identify their distinct functions in living animals.
