History in the making: Whistleblowers and big tech

open access: yesFirst Monday
The recent history of computing has been drafted in the press as the story of corporations and the men who lead them. Another story, reported on widely but often less explicitly connected by the general public to the progress of computing history is the story of the people — mostly women, and mostly women of color — who have been engaged in various ...

Tyrosinase Driven‐Intracellular Polymerization of a Porphyrin Derivative Induced Immunogenic Death of Melanoma Cells and Strengthened Photodynamic Therapy

open access: yesAdvanced Science, EarlyView.
This study uses tyrosinase, which is highly expressed in melanoma, to drive porphyrins to polymerize and self‐assemble within tumor cells to form retented microstructures. This process induces immunogenic death and activates immune responses (M1 macrophages, dendritic cells, CD8+T cells), turning “cold” tumors into “hot” tumors.

Ultrafast, High‐Capacity Uranium Harvesting From Seawater via a Hierarchically Porous Polymer Electrode

open access: yesAdvanced Science, EarlyView.
A hierarchically porous AOPIM‐CNT electrode enables uranium harvesting from seawater via adsorption‐promoted electrodeposition. Rapid diffusion and selective adsorption are coupled with electrochemical crystallization and spontaneous detachment, creating a self‐refreshing process that sustains high‐capacity, continuous extraction from ultradilute ...

Big Tech in Österreich

open access: yes
‘Big Tech’ hat die Welt grundlegend verändert.  Wir profitieren von Big Tech durch eine Reihe neuer Technologien und Dienste, die oft unentgeltlich – allerdings gegen Preisgabe persönlicher Daten – angeboten werden. Viele sehen den Einfluss von Big Tech auf Bereiche des täglichen Lebens aber auch mit zunehmender Skepsis.

Selective Interfacial Barriers Drive High‐Performance GeTe Thermoelectrics

open access: yesAdvanced Science, EarlyView.
Carrier‐phonon decoupling is the key to developing high‐performance thermoelectric materials. Here, we demonstrate that selective interfacial barriers can decouple carrier and phonon transport, thus achieving an exceptional peak ZT of ∼2.7 at 773 K, along with a record‐high average ZT of 1.9 across 300–773 K in the (Ge0.82Mn0.04Bi0.04Pb0.1Te)0.99(VSe2 ...

Allosteric DNAzyme‐Enabled Sensitive and Multiplex Detection of Biomarkers for Rapid Diagnosis of Urinary Tract Infections

open access: yesAdvanced Science, EarlyView.
A catalytic allosteric DNAzyme assay (SMART) is developed by engineering DNAzyme into a unimolecular biosensor, enabling highly sensitive and multiplex detection of small molecules and nucleic acids. SMART enables extraction‐free, one‐pot, one‐step, isothermal, and cost‐effective detection of biological markers, achieving >95% accuracy for rapid ...

Virginia Tech Forestry Department Updates Virginia Big Tree Database

open access: yes, 2003
Virginia's Big Tree Program has an updated database, thanks to Virginia Tech's Department of Forestry. In the past, the big tree database was a table of the most common species of champion trees.

Giant Conductivity Modulation and Chemical Neuromodulation via Proton‐Electron Coupling in a Hydrogen‐Bonded Coordination Polymer

open access: yesAdvanced Science, EarlyView.
A “de‐doping” strategy positions mixed protonic–electronic conductors (MPECs) as adaptive neuromorphic platforms with dynamically tunable transport. Co‐BAND achieves giant conductivity modulation (>106) and chemically tunable synaptic plasticity. Analogous to biological neuromodulation, solvent vapors dynamically reprogram the device's learning rules ...
