Dephasing enabled fast charging of quantum batteries
We propose and analyze a universal method to obtain fast charging of a quantum battery by a driven charger system using controlled, pure dephasing of the charger. While the battery displays coherent underdamped oscillations of energy for weak charger dephasing, the quantum Zeno freezing of the charger energy at high dephasing suppresses the rate of transfer of energy to the battery. Choosing an optimum dephasing rate between the regimes leads to a fast charging of the battery. We illustrate our results with the charger and battery modeled by either two-level systems or harmonic oscillators. Apart from the fast charging, the dephasing also renders the charging performance more robust to detuning between the charger, drive, and battery frequencies for the two-level systems case.

Extracellular vesicles from antler blastema progenitor cells reverse bone loss and mitigate aging-related phenotypes in mice and macaques
Antler blastema progenitor cells (ABPCs) are a distinct population of skeletal mesenchymal stem cells found in regenerating deer antlers, with strong stemness and renewal capacity in vitro. Stem cell-derived extracellular vesicles (EVs) are emerging as potential therapeutic candidates that can mediate donor cells’ beneficial effects. Here, we tested the effects of ABPC-derived EVs (EVsABPC) on aging in mice and rhesus macaques (Macaca mulatta). We identified a variety of unique factors in EVsABPC and showed that in vitro, EVsABPC attenuated phenotypes of senescence in bone marrow stem cells. In aged mice and macaques, EVsABPC substantially increased femoral bone mineral density. Further, intravenous EVsABPC improved physical performance, enhanced cognitive function and reduced systemic inflammation in aged mice, while reversing epigenetic age by over 3 months. In macaques, EVABPC treatment was also neuroprotective, reduced inflammation, improved locomotor function and reduced epigenetic age by over 2 years. Our findings position ABPCs as an emerging and practical source of EVs with translational value for healthy aging interventions.
Inspired by the regenerative capacity of deer antlers, Hao and colleagues report that antler blastema progenitor cell-derived extracellular vesicle treatment counteracts bone loss and epigenetic aging and is neuroprotective in mice and macaques.
Hunting for quantum-classical crossover in condensed matter problems
The intensive pursuit for quantum advantage in terms of computational complexity has further led to a modernized crucial question of when and how will quantum computers outperform classical computers. The next milestone is undoubtedly the realization of quantum acceleration in practical problems. Here we provide a clear evidence and arguments that the primary target is likely to be condensed matter physics. Our primary contributions are summarized as follows: 1) Proposal of systematic error/runtime analysis on state-of-the-art classical algorithm based on tensor networks; 2) Dedicated and high-resolution analysis on quantum resource performed at the level of executable logical instructions; 3) Clarification of quantum-classical crosspoint for ground-state simulation to be within runtime of hours using only a few hundreds of thousand physical qubits for 2d Heisenberg and 2d Fermi-Hubbard models, assuming that logical qubits are encoded via the surface code with the physical error rate of p = 10–3. To our knowledge, we argue that condensed matter problems offer the earliest platform for demonstration of practical quantum advantage that is order-of-magnitude more feasible than ever known candidates, in terms of both qubit counts and total runtime.

Subaru telescope uncovers ancient ‘fossil’ object in outer Solar System
Far beyond Pluto, icy wanderers known as Trans-Neptunian Objects (TNOs) drift through the vast cosmic depths. Some of them orbit at incredible distances, more than 200 times farther from the Sun than Earth, making them tough to spot, but priceless to study.
These elusive objects may hold secrets to how the Solar System formed, and even hint at the presence of a mysterious Planet Nine lurking in the shadows.
Now, the Subaru Telescope has spotted a new one: a small, distant body that’s helping scientists piece together the puzzle of our solar neighborhood’s past and its still-unfolding future.
