Ida Carrie Seale in her nurse's uniform, shortly before her graduation from the Nurses Training School at Charity Hospital in New Orleans, Louisiana.

open access: yes, 1903
The following note accompanies the image: "Made 1903, a short time before graduation. The uniforms were two inches from the floor. The high stiff collars and long sleeves were worn summer and winter, along with three petticoats, a heavy corset, and other

Sticky Yet Slippery: Molecular Ordering Reconciles Bubble‐Surface Affinity With Ultralow Friction at the Nanoscale

open access: yesAdvanced Science, EarlyView.
By engineering the molecular order and thickness of PDMS layers, we reconcile the stickiness and slipperiness during bubble transport. AFM measurements and MD simulations further reveal how these nanoscale architectures tune hydrophobic interaction FHB and friction force f.

Wireless, Deep‐Seeing Smart Pill: A NIR‐II Fluorescence Imaging Capsule Endoscope for Gastrointestinal Cancer

open access: yesAdvanced Science, EarlyView.
A novel near‐infrared‐II fluorescent imaging capsule endoscope that detects specific fluorescence signals above 900 nm enables highly sensitive, targeted imaging of gastrointestinal cancer tissue. This wirelessly powered and magnetically controlled “smart pill” achieves high sensitivity and deep tissue penetration, allowing precise, non‐invasive ...

Unity Quantum Yield of High‐Entropy Quantum Dots Composited With Photonic Crystals for Information Encryption

open access: yesAdvanced Science, EarlyView.
This study first extends the high‐entropy concept to I‐III‐VI quantum dots (QDs) and synthesizes CZCrGSe/ZnSe/ZnS core/shell/shell QDs with a record photoluminescence quantum yield (PLQY) of 100%. Their ZnSe/ZnS double shell efficiently passivates defects and boosts structural stability.

Conservative management of low back pain

open access: yes, 2001
Back pain is prevalent worldwide, but back pain disability has reached epidemic proportions in many industrialised societies. Few patients have serious medical pathology or direct neurological involvement requiring surgery.

Inhibitory Decay and Supercritical Brain Dynamics During Sleep Deprivation

open access: yesAdvanced Science, EarlyView.
Sleep deprivation progressively shifts human brain dynamics from near‐critical toward supercritical states, as revealed by neuronal avalanche analysis of resting‐state fMRI. These changes track subjective sleep pressure rather than vigilance lapses and show marked network heterogeneity. A circuit model suggests that reduced inhibitory efficacy provides
