Two machine learning algorithms can determine whether a whiskey is of American or Scotch origin and identify its strongest aromas, according to research published in Communications Chemistry. The results also suggest that the algorithms can outperfor.....»»
YouTube populists are driving South Korea"s political instability—a warning for the rest of the world"s democracies
In the space of three weeks, South Korea has seen a brief declaration of martial law, its sudden repeal and the impeachment of its president, Yoon Suk Yeol......»»
Harmful gas billowing from Texas and New Mexico comes mostly from smaller leaks, researchers say
The blob on the satellite image is a rainbow of colors. An analyst digitally sharpens it and there, highlighted in red, is the source: a concrete oil pad spewing methane......»»
Scientists recreate molecular timers to control nanomachine activation rates
Living organisms monitor time—and react to it—in many different ways, from detecting light and sound in microseconds to responding physiologically in pre-programmed ways, via their daily sleep cycle, monthly menstrual cycle, or to changes in the.....»»
Sentinel-1 data reveals Arctic glacier retreat
As Arctic temperatures rise, marine-terminating glaciers—especially in places like Svalbard—are undergoing rapid retreat and intensified calving. The Space for Shore project utilizes radar data from the Copernicus Sentinel-1 mission to provide pr.....»»
Machine learning offers new framework for heterogeneous catalyst data analysis
Machine learning (ML) transforms the design of heterogeneous catalysts, traditionally driven by trial and error due to the complex interplay of components. BIFOLD researcher Parastoo Semnani from the ML group of BIFOLD Co-Director Klaus-Robert Mülle.....»»

Two astronauts who traveled to space on the troubled Boeing Starliner spacecraft will have their stay extended a little longer......»»
Amazon’s RTO delays exemplify why workers get so mad about mandates
Amazon lacks space to accommodate its entire workforce. Amazon announced in September that it will require workers to be in the office five days a week starting in January. Emplo.....»»
Massive volcanic eruptions did not cause the extinction of dinosaurs, say climate scientists
Massive volcanic eruptions on the Indian peninsula have long been proposed as an alternative cause for the demise of the dinosaurs. This phase of active volcanism took place in a period just before Earth was struck by a meteorite, 66 million years ag.....»»
Clouds obscure link between extreme rainfall and rising temperatures
Extreme rainfall is usually defined as the heaviest 5% of rain events in a specific area. As global air temperatures rise, scientists expect extreme rainfall to increase. This is because warmer air can hold more moisture. Recent examples of more extr.....»»
Astronaut-on-a-chip: Multi-organ tissue chips simulate space radiation"s impact on human health
As astronauts venture further into space, their exposure to harmful radiation rises. Researchers from Columbia University are simulating the effects of space radiation here on Earth to determine its impact on human physiology using multi-organ tissue.....»»
