All-Optical Microfluidics: Leveraging Photothermal Effects to Create Reprogrammable, Non-Invasive Virtual Valves and Pumps for High-Throughput Single-Cell Analysis.

All-Optical Microfluidics: Leveraging Photothermal Effects to Create Reprogrammable, Non-Invasive Virtual Valves and Pumps for High-Throughput Single-Cell Analysis.

Conventional microfluidic systems, the "lab-on-a-chip" technologies that underpin much of modern biology and chemistry, rely on a hardware-based paradigm. Their channels, mixers, valves, and pumps are physically etched into materials like glass or PDMS, creating a fixed and immutable architecture. This approach, while powerful, suffers from inherent limitations:

Tomographic Volumetric Additive Manufacturing: Using Spatiotemporally Sculpted Light to Solidify an Entire Volume of Photopolymer Resin at Once, Enabling Support-Free, Millisecond-Scale 3D Fabrication.

Tomographic Volumetric Additive Manufacturing: Using Spatiotemporally Sculpted Light to Solidify an Entire Volume of Photopolymer Resin at Once, Enabling Support-Free, Millisecond-Scale 3D Fabrication.

Conventional 3D printing, or additive manufacturing (AM), has fundamentally changed prototyping and manufacturing by building objects layer-by-layer. However, this sequential approach suffers from inherent limitations: it is often slow, requires extensive support structures for complex geometries, and introduces anisotropic mechanical properties due to the layered interfaces. A revolutionary new paradigm,

Axion Haloscopes as a Probe for Dark Matter: Using Resonant Microwave Cavities in High Magnetic Fields to Detect the Conversion of Galactic Axions into Photons

The existence of dark matter is one of the most profound puzzles in modern physics, inferred from its gravitational effects on galaxies and the large-scale structure of the universe, yet its composition remains unknown. Among the leading candidates is the axion, a hypothetical elementary particle originally proposed to solve the

Sonocatalytic Degradation of Per- and Polyfluoroalkyl Substances (PFAS): Leveraging Acoustic Cavitation to Break Strong Carbon-Fluorine Bonds in Environmental Remediation

Per- and polyfluoroalkyl substances (PFAS) represent a class of thousands of synthetic chemicals characterized by chains of carbon atoms saturated with fluorine atoms. The carbon-fluorine (C-F) bond is one of the strongest in organic chemistry, granting these compounds exceptional thermal and chemical stability. This has made them invaluable in a

Magnetoencephalography with Diamond Nitrogen-Vacancy Centers: Using Quantum Defects to Non-Invasively Map Neural Oscillations at Unprecedented Spatiotemporal Resolution

Magnetoencephalography (MEG) stands as a powerful, non-invasive neuroimaging technique that directly measures the faint magnetic fields generated by synchronous neural activity. It offers superior temporal resolution to functional magnetic resonance imaging (fMRI), tracking brain processes on a millisecond scale. However, conventional MEG technology is fundamentally constrained by its reliance on

Closed-Loop Autonomous Systems for Accelerated Materials Discovery: Integrating Robotic Synthesis, In-Situ Characterization, and AI-Driven Hypothesis Generation

The discovery of advanced materials has historically been the engine of human progress, from the Stone Age to the Silicon Age. However, the traditional process of materials discovery is notoriously slow, expensive, and reliant on a combination of intuition, serendipity, and painstaking trial-and-error. In a world facing urgent challenges in

Myco-metallurgy: Engineering Fungal Networks for the Selective Bio-extraction of Rare Earth Elements from E-Waste

The exponential growth of consumer electronics has engendered a parallel crisis: a burgeoning mountain of electronic waste (e-waste) laden with both toxic materials and valuable metals. Within this waste stream lies a particularly critical resource: rare earth elements (REEs), which are indispensable for modern technologies ranging from smartphones and electric

Triboelectrification in Aeolian Sediment Transport: Unveiling the Role of Granular Electrodynamics in Dune Morphogenesis on Terrestrial and Martian Landscapes

Triboelectrification, the process by which materials become electrically charged after coming into contact and then separating, is a ubiquitous phenomenon in granular media undergoing aeolian (wind-driven) transport. This mechanism not only influences particle motion and aggregation but also shapes the morphogenesis of dunes and dust activity across Earth and Mars.

Reconstructing Endogenous Viral Elements from Paleogenomic Data to Model Ancient Host-Pathogen Immune Co-evolution

Reconstructing Endogenous Viral Elements from Paleogenomic Data to Model Ancient Host-Pathogen Immune Co-evolution

Endogenous viral elements (EVEs), remnants of ancient viral infections archived within host genomes, provide a unique molecular record of past host-pathogen interactions. Paleogenomic approaches have begun to unlock these traces from ancient DNA (aDNA) recovered from subfossil or permafrost-preserved remains, offering new perspectives on how viral insertions have influenced host
