Advanced Science, EarlyView.CDegSR, a new tool for imaging RNA at single molecule level in living cells was developed by researchers. Background noise was eliminated by protein engineering and making it degrade when not bound to its target. This allowed individual RNA molecules to be clearly imaged and tracked.

Brownian Motion on a Submanifold [PDF]
Communications in Analysis and Geometry, 2004 Consider an \(n\)-dimensional complete Riemannian manifold \(N\), and a closed \(m\)-dimensional submanifold \(M\). Using that the Laplacian on \(N\) is got by projection of the horizontal Laplacian on \(O(N): (\Delta^N\varphi)\circ\pi= \sum^n_{i=1} (H^N_i)^2(\varphi\circ\pi)\), one obtains classically the Brownian motion on \(N\) as \(\pi(p^N_t ...

Self‐Propelled HPB@Lip@AB Nanomotors Ameliorate Dry Eye Disease
Advanced Science, EarlyView.A self‐propelled HPB@Lip@AB nanomotor system is developed for dry eye disease (DED) therapy, facilitating rapid penetration across ocular surface barriers while integrating hydrogen therapy with multi‐enzyme‐like antioxidant activity. The nanoplatform restores mitochondrial function, suppresses oxidative stress, inflammation, and apoptosis, and ...

Flow and Heat Transfer to Sisko Nanofluid over a Nonlinear Stretching Sheet.
PLoS ONE, 2015 The two-dimensional boundary layer flow and heat transfer to Sisko nanofluid over a non-linearly stretching sheet is scrutinized in the concerned study. Our nanofluid model incorporates the influences of the thermophoresis and Brownian motion.

Physical Brownian motion in magnetic field as rough path [PDF]
, 2013 The indefinite integral of the homogenized Ornstein-Uhlenbeck process is a well-known model for physical Brownian motion, modelling the behaviour of an object subject to random impulses [L. S. Ornstein, G. E.

Advanced Science, EarlyView.High‐throughput Differential Dynamic Microscopy measures frequency‐resolved mechanical fingerprints from 3 to 10 μL$\umu{\rm L}$ mucus samples using only a few minutes of operator attention per sample. This automated analysis enables scalable mucus phenotyping for translational research by distinguishing mechanical heterogeneity among donors, disease ...

Detecting non-Brownian trait evolution in adaptive radiations.
PLoS Biology, 2006 Many phylogenetic comparative methods that are currently widely used in the scientific literature assume a Brownian motion model for trait evolution, but the suitability of that model is rarely tested, and a number of important factors might affect ...

A Continuous Super-Brownian Motion in a Super-Brownian Medium
, 1997 A continuous super-Brownian motion XQ is constructed in which branching occurs only in the presence of catalysts which evolve themselves as a continuous super-Brownian motion Q .

Advanced Science, EarlyView.The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.

Coacervate Droplet Sequestration of Heterogeneous Nanoplastics With Elastin‐Like Polypeptides
Angewandte Chemie, EarlyView.Phase‐separated polypeptide droplets captured incidental nanoplastics as a reusable nanoplastic sink. The engineered droplets selectively partitioned nanoplastics and exhibited unique interactions depending on droplet type and nanoplastic identity, establishing biopolymer coacervates as a potential platform for nanoplastic characterization and removal.
