Molecular characterization of a marine turtle tumor epizootic, profiling external, internal and postsurgical regrowth tumors

open access: yesCommunications Biology, 2021
Yetsko, Farrell, Duffy, and colleagues conduct transcriptomic and immunohistological profiling of tumors from sea turtles with fibropapillomatosis. Internal tumors are distinct from more common external tumors, but share some oncogenic signaling pathways

Reprogrammable Phase‐Transition Composites for Adaptive Dynamic Shape Morphing

open access: yesAdvanced Science, EarlyView.
This paper reports a bio‐inspired reprogrammable phase‐transition composites that uses the stiffness change induced by reversible solid‐liquid phase transition to program and regulate the material deformation actuated by reversible liquid‐vapor phase transition, thereby achieving adaptive dynamic deformation in a controllable manner, and enabling ...

Comparison of Harvested and Nonharvested Painted Turtle Populations [PDF]

open access: yes, 2004
Painted turtles (Chrysemys picta) are commercially harvested in large numbers in Minnesota for sale to biological supply companies and the pet trade. We investigated the possible effects of this harvest by comparing size, demography, and catch rates of ...

Self‐Healing Starch‐Based Ionogels with Hydroneutral Dipole–Dipole Interactions

open access: yesAdvanced Science, EarlyView.
This work introduces starch‐based, conductive, underwater‐healable, and transparent ionogels for soft electronics (SCUTEs). Starch macromolecules are partially substituted with cyanoethyl groups and incorporated with hydrophobic ionic liquid. The polar yet hydroneutral cyanoethyl groups facilitate strong dynamic dipole–dipole interactions that remain ...

Automatic Determination of Quasicrystalline Patterns from Microscopy Images

open access: yesAdvanced Intelligent Discovery, EarlyView.
This work introduces a user‐friendly machine learning tool to automatically extract and visualize quasicrystalline tiling patterns from atomically resolved microscopy images. It uses feature clustering, nearest‐neighbor analysis, and support vector machines. The method is broadly applicable to various quasicrystalline systems and is released as part of
