Use caution with the word ‘shelter’ in lightning safety

Progress in Disaster Science
In some countries, lightning causes more deaths than other weather events more commonly thought of as disasters, so there is a need for safe refuges during thunderstorms.

Temporal Interference Stimulation Enhances Neural Regeneration

Advanced Science, EarlyView.
Temporal interference (TI) stimulation is proposed as a non‐invasive approach to enhance neural regeneration in the deep brain. Theta‐band TI modulation selectively promotes neural progenitor cell differentiation in vitro and augments hippocampal neurogenesis in amouse model of Alzheimer's disease‐like amyloidosis.

MiR‐940 Suppresses Ferroptosis by Controlling Expression of Key Regulatory Genes

Advanced Science, EarlyView.
A CRISPR‐based screening identified miR‐940 as a critical suppressor of ferroptosis in cancer. By coordinating the downregulation of pro‐ferroptotic genes with the upregulation of GPX4, miR‐940 establishes a regulatory network that protects against ferroptosis and correlates with poor clinical outcomes in distinct cancer entities.

Assigning the causative lightning to the whistlers observed on satellites [PDF]

Annales Geophysicae, 2006
We study the penetration of lightning induced whistler waves through the ionosphere by investigating the correspondence between the whistlers observed on the DEMETER and MAGION-5 satellites and the lightning discharges detected by the European ...

An Implantable Phototriggered Prodrug Depot Patch Enables Actively Programmable Drug Release for Post‐Myocardial Infarction Therapy

Advanced Science, EarlyView.
An implantable phototriggered prodrug depot patch (iPDP) is presented that enables actively programmable drug release post‐implantation. Covalently conjugated prodrug ensures minimal leakage; illumination parameters serve as a code to precisely control dose per release.

Translating Blue Light Stimulation From Batch to Perfusion: Process and Intracellular Metabolic Analysis

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Improving cell‐specific productivity remains a central objective in biopharmaceutical manufacturing. In this study, the effect of blue light illumination on IgG1‐producing CHO DP‐12 cells was systematically evaluated across batch, fed‐batch, and perfusion cultivations in controlled 3 L bioreactor systems.
