IGF‐1 Deficiency Serves as an Integrated Biomarker Pathogenic Driver and Predictor in Poor Ovarian Response

open access: yesAdvanced Science, EarlyView.
IGF‐1 deficiency underlies poor ovarian response (POR), as reduced levels in follicular fluid and granulosa cells impair antral follicle formation and compromise reproductive outcomes. Including IGF‐1 as a biomarker significantly enhances the accuracy of models predicting both PORrisk and pregnancy success.

Protease‐Activated Plasmonic Nanosensors for Predictive Ultrasound‐Guided Photoacoustic Imaging of Tumor Responses to Adoptive T Cell Therapy

open access: yesAdvanced Science, EarlyView.
Protease‐activated plasmonic nanosensors are demonstrated to noninvasively monitor antitumor T cell activity in tumors with anatomical information upon adoptive T cell transfer via ultrasound‐guided photoacoustic imaging. These nanosensors are actuated by granzyme B, a protease secreted by activated cytotoxic T cells during tumor cell killing, which ...

Photocatalytically Activated Cu‐N1S3 Single‐Atom Nanozyme: Enhancing Enzyme Activities and Antibacterial Synergy for Highly Efficient Fruit Preservation

open access: yesAdvanced Science, EarlyView.
This study presents S‐coordinated Cu single‐atom nanozymes (Cu/CNS) fabricated via mild photocatalytic self‐assembly strategy. The nanozyme exhibits exceptional multi‐enzyme activity and near‐perfect antimicrobial efficacy. Incorporated into chitosan‐gelatin film, it enables pH‐responsive, broad‐spectrum fruit preservation, more than doubling the shelf‐

Retelling the Story of the Birds and the Bees in the Age of Biodiversity Extinction

open access: yesLanguages
John Lovejoy coined the term biological diversity in 1980, made the first projection of global extinction rates, and 43 years later we are still discussing biodiversity and extinction in an inconsequential fashion.

AI‐Driven Acceleration of Fluorescence Probe Discovery

open access: yesAdvanced Science, EarlyView.
We present PROBY, an AI model trained on large‐scale datasets to predict key photophysical properties and accelerate the discovery of target‐specific fluorescent probes. By screening a target‐annotated library, PROBY identifies candidate probes for diverse targets and could guide probe optimization, enabling a range of in vitro and in vivo imaging ...

Correlates of avian extinction timing around the world since 1500 CE

open access: yesAvian Research
Avian extinctions have been relatively well documented in modern history, and in the past millennia, more bird species are known to have gone extinct than species in any other vertebrate class.

Arbitrary 3D Organic Mixed Ionic‐Electronic Conductor Architectures via Self‐Fusion of PEDOT:PSS Microfibers

open access: yesAdvanced Science, EarlyView.
A general fabricating strategy for arbitrary 3D organic mixed ionic‐electronic conductor architectures is reported using PEDOT:PSS microfiber building blocks. A water‐assisted self‐fusion process is successfully developed in which adhesion can be modulated as reversible (PSS‐rich) or irreversible (PEDOT‐rich) self‐fusion depending on the post‐treatment

The rise and fall of Varanopidae† (Amniota, Synapsida)

open access: yesFrontiers in Earth Science
Study of past biological crises is now a timely topic because we may be in the midst of an anthropogenic mass extinction event. A skyline Fossilized Birth-Death (FBD) analysis of a dataset of 21 varanopid taxa, ranging in geological age from the mid ...
