Reservoir computing is a promising machine learning-based approach for the analysis of data that changes over time, such as weather patterns, recorded speech or stock market trends. Classical reservoir computing techniques are known to perform best at the "edge of chaos," or in simpler terms, at a "sweet spot" in which the behavior of systems is neither entirely predictable (i.e., order) nor completely unpredictable (i.e., chaos).

Scientists at the U.S. Naval Research Laboratory (NRL) have identified the true source of a magnetic effect seen in the material ruthenium dioxide (RuO₂), helping resolve an active debate in the rapidly growing field of altermagnetism. The study is published in the journal ACS Applied Materials & Interfaces.

Messages intended to suppress votes can be precisely delivered to particularly vulnerable and consequential groups of people via social media and keep millions of them from casting ballots, according to a new study that is the first to quantify the effect of this kind of microtargeting on voter turnout. A team led by a researcher at the University of Wisconsin–Madison recruited more than 10,000 people across the United States—a group representative of the country's voting population—to install an app that captured every ad they viewed for the six weeks leading up to the November election in 2016.

Every year, billions of birds undertake extraordinary migrations, crossing vast deserts and open seas with no place to stop, feed, or rest. A new international study published in iScience by a consortium of researchers from Tour du Valat, CEFE/CNRS, Muséum national d'Histoire naturelle and Swiss Ornithological Institute reveals that small migratory birds adjust how high they fly over these ecological barriers, and that their strategies depend on wing morphology and plumage color.

Green hydrogen production technology, which utilizes renewable energy to produce eco-friendly hydrogen without carbon emissions, is gaining attention as a core technology for addressing global warming. Green hydrogen is produced through electrolysis, a process that separates hydrogen and oxygen by applying electrical energy to water, requiring low-cost, high-efficiency, high-performance catalysts.
