Advanced Science, EarlyView.This seminal study highlights the interwoven and tightly regulated functions of brain‐derived extracellular vesicles. Using microfluidics, proteomics, and AI‐based electric signal analyses of cortical brain explants, this work provides a useful resource dataset revealing the composition of human brain‐derived extracellular vesicles obtained from ...

Chemical abundance of comets [PDF]
Observations of NH2, (OI) and molecular ion spectra in comets represent virtually all of the volatile fraction of a comet nucleus. Their study leads to the N2, NH3, H2O, CO2, CO content of the nucleus, and thus to important constraints on models of comet

Advanced Science, EarlyView.The Bimetallic Nanozyme Amplifier (PEG@AuCZ@CC) to maximize hydrogen peroxide production and reprogram tumor metabolism from glycolysis to oxidative phosphorylation. This shift enhances ferroptotic/cuproptotic signaling cascades and creates a glucose‐enriched but lactate‐depleted tumor microenvironment (TME), effectively overcoming immune tolerance in ...

Near-Earth Asteroids as Possible Parent Bodies of Meteor Streams [PDF]
Учёные записки Казанского университета: Серия Естественные науки, 2016 The genetic relationship of meteor streams with near-Earth asteroids (NEAs) is being actively studied. A genetic link with the asteroid is possible only for streams in which meteoroids have the geocentric speed smaller than 50 km/s, thereby meaning the ...

Single‐Cell Nucleus Extraction with Cellular Indexing
Advanced Science, EarlyView.VacTrap is a multilayer, high‐throughput microfluidic system that isolates and spatially indexes single nuclei from hundreds of cells within minutes. Using dissolvable hydrogel trapdoors triggered by chemical and vacuum actuation, VacTrap synchronously transfers nuclei while preserving spatial links to parent cells.

GALEX FUV Observations of Comet C/2004 Q2 (Machholz): The Ionization Lifetime of Carbon
, 2010 We present a measurement of the lifetime of ground state atomic carbon, C(^3P), against ionization processes in interplanetary space and compare it to the lifetime expected from the dominant physical processes likely to occur in this medium.

Crater Observing Bioinspired Rolling Articulator (COBRA)
Advanced Intelligent Systems, EarlyView.Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.
