Localizable Fluorescent Metal Ion Indicators With Tunable Colors

Advanced Science, EarlyView.
A modular platform enables the generation of fluorescent metal ion indicators with tunable emission colors and precise subcellular localization. Conjugation to self‐labeling proteins yields bright, color‐tunable potassium probes that permit wash‐free live‐cell imaging, revealing dynamic potassium efflux in stimulated neurons.

Bayesian updating to estimate extinction from sequential observation data

, 2018
Several new approaches to estimating the probability that a species is extinct have emerged recently. Different foundational assumptions can lead to different interpretations of data and potentially to different conclusions.

Biological recycling theory: a cyclic network framework for evolutionary innovation and recovery

Frontiers in Ecology and Evolution
IntroductionLife’s macroevolutionary patterns—rapid post-extinction recoveries and bursts of novelty—are not fully explained by mutation and vertical descent alone.

A Dual‐Channel Synergistic Ultrasensitive Biosensor for Tumor Liquid Biopsy

Advanced Science, EarlyView.
ABSTRACT Liquid biopsy technology, which detects circulating tumor DNA (ctDNA) in cerebrospinal fluid, plays a crucial role in the early diagnosis and precision treatment of gliomas. However, the intrinsically low abundance and rapid clearance of ctDNA pose substantial challenges for conventional analytical techniques, such as droplet digital PCR and ...

HARVESTING STRATEGIES IN A FISH STOCK DOMINATED BY LOW-FREQUENCY VARIABILITY: THE NORWEGIAN SPRING-SPAWNING HERRING (CLUPEA HARENGUS)

Heavy positively autocorrelated natural fluctuations in a fisheries stock level are problematic for fisheries management, and collapses in the stock dynamics are difficult to avoid.

Detecting extirpation: A localized approach to a global problem

Plants, People, Planet
Societal Impact Statement The global biodiversity crisis stems from a cascading series of extirpations driving species toward extinction. Addressing this crisis requires methods for early detection of extinction at local scales, where communities can ...

Triple‐Mode Ferroelectric Thin‐Film Transistor for Hybrid Electrical–Optical Reservoir Computing

Advanced Science, EarlyView.
A triple‐mode ferroelectric thin‐film transistor is developed by integrating Si3N4/HZO/IGZO layers to realize three independent memory modes: electric long‐term, electric short‐term, and optical short‐term. This single‐device architecture functions as both a reservoir and readout layer, achieving 92.43% MNIST accuracy. It offers a fully hardware‐based,

A Novel Approach Based on Acceptor–Donor–Acceptor Type Molecules Enhances the Therapeutic Efficacy and Safety of Photothermal Therapy for Osteosarcoma

Advanced Science, EarlyView.
Jin et al. developed IEICO‐F nanoparticles with enhanced photothermal conversion efficiency via optimized push‐pull effect. Under 808 nm laser, these nanoparticles effectively generated heat to kill osteosarcoma cells and exhibited significant tumor suppression in vivo. Therefore, this novel A‐D‐A type molecule‐based photothermal therapy strategy holds

First extinction risk assessment of a bryophyte species in Antarctica

Oryx
Assessing extinction risk is important for protecting species, as it is the starting point for conservation efforts. However, in Antarctica, none of the c. 116 species of bryophytes (the main terrestrial plant group) have been assessed.
