Technological innovation has been crucial in the evolution of our lineage, with tool use and production linked to complex cognitive processes. While previous research has examined the cognitive demands of early stone toolmaking, the neurocognitive aspects of early hominin tool use remain largely underexplored. This study relies on electroencephalography to investigate brain activation patterns associated with two distinct early hominin tool-using behaviors: forceful hammerstone percussion, practiced by both humans and non-human primates and linked to the earliest proposed stone tool industries, and precise flake cutting, an exclusive hominin behavior typically associated with the Oldowan.

Bischofite salt (MgCl·6HO) has garnered significant attention due to its wide range of industrial applications. Efficient hydrogen production in arid or hyper arid locations using bischofite solutions is a novel and revolutionary idea.

- This review covers key aspects of corrosion inhibitors, the mechanisms behind corrosion and inhibition in NaCl, characterization techniques, theoretical models, and guidelines for selecting corrosion inhibitors to enhance research in this field.
Article Synopsis
- * The decay of ^{6}He into ^{4}He, a neutron, and a dark matter particle (χ) allows for clear detection when using an efficient neutron detector.
- * A recent experiment at Grand Accélérateur National d'Ions Lourds set an upper limit on the dark decay branching ratio and provided improved constraints on dark neutron decays, making them significantly more precise than previous findings.
Article Synopsis
- Automated high-throughput workflows are gaining importance for optimizing material stability, but many limitations exist, such as the use of unsuitable synthesis techniques and ambient conditions that hinder result transferability.
- This study focuses on MAPbI thin films to demonstrate a new combinatorial inert-gas workflow for assessing materials' intrinsic degradation under controlled environments, simulating encapsulated device conditions.
- Utilizing advanced automated characterization techniques and a custom UV-Vis aging setup, the research reveals insights into degradation kinetics and phase changes, supported by a machine learning model that connects optical spectra variations to aging processes, enabling better comparison of material stability across multiple samples.
