The TRAPPIST-1 system, located about 41 light years from Earth, has been a focal point of much exoplanetary discussion—mainly because it has seven confirmed planets orbiting a dim M-dwarf star. Two of those planets—TRAPPIST-1e and -1f—are thought to be in the star's habitable
A part of the Atlantic Ocean, just south of Greenland and Iceland, has been cooling off while the rest of the world gets hotter. This enigmatic patch is often referred to as the "cold blob" and scientists have been trying to figure out the mechanisms behind its cooling. While
Typically, the information encoded in DNA allows organisms to develop, function, and pass traits across generations. Yet DNA alone does not explain how genes are switched on and off in different cells and environments. This regulation is partly controlled by other factors
A common explanation for why waste management sometimes fails is that carelessness breeds more carelessness. Now, research from the University of Gothenburg shows that dirty waste disposal rooms can evoke feelings of disgust that increase the risk of people disposing of their
Colloidal photonic glasses offer an appealing way to produce vivid colors without any chemical dyes—but so far, a stubborn optical effect has long prevented them from generating a true red color. Now, Yuwon Jeon and colleagues at KU-KIST in Seoul have developed a new approach
Incorporating more plant-based proteins could help people save on their grocery bill, but new research has found that it's not so simple when it comes to choices at the supermarket. Simon Fraser University researchers peeked into more than 87,000 grocery carts in Canada and
Biophotonics is a multidisciplinary field that involves the development and application of light-based technologies to study, monitor and treat biological systems. The ability to directly image cells and molecules has led to many fundamental discoveries in the past century.
For millions of people, chatbots powered by large language models (LLMs) are now a key feature of everyday life. These AI systems are growing at a rapid pace, but scaling them up is becoming increasingly costly and resource-intensive.
An experiment with 2,520 participants backs Richard Feynman’s answer to every diner’s dilemma: do I want to try something new?
Computational point-of-care sensors can significantly improve access to diagnostics by enabling rapid patient testing outside centralized medical facilities. These tests rely on machine learning models to make diagnostic predictions, but such inference models are susceptible to
Imagine a train parked at the station. Passengers climb aboard and find their seats. Conductors move up and down the aisles, checking tickets. But there's a problem—the engineer's watch is broken. As a result, the doors never close, the whistle never sounds, and the train never
Scientists have discovered a previously unknown regulatory mechanism in plant photosynthesis in the unicellular green alga Chlamydomonas reinhardtii. It helps plants adapt to changes in light conditions. The results, published in the journal Nature Plants, show how a crucial
Thousands of small earthquakes, detected for the first time by a machine-learning process, reveal the distinct, razor-sharp edge of the Yakutat microplate as it subducts beneath the North American plate.
A traditional Chinese medicinal root used for over a thousand years is attracting new scientific attention for its potential to combat hair loss. Studies suggest Polygonum multiflorum can block harmful hormones, activate hair-growth signals, protect follicles, and boost blood
Researchers have finally resolved a key problem in a 100-year-old theory of color, showing that the qualities we perceive in colors are intrinsic to the mathematics of color space itself. The discovery sharpens our understanding of human vision and could lead to more precise
Having Black teachers and other educators of color improves students' classroom experiences, research shows. They often serve as role models, set high academic expectations and teach material that connects to students' lives outside of schools.
A new study published in the Proceedings of the National Academy of Sciences demonstrates how radiocarbon dating can reveal the maximum lifespan of Mediterranean hardwoods, uncovering hidden links between human history and long-term ecosystem dynamics. By analyzing mature and
Americans rarely marry outside of their race or class in a nation where residential segregation is relatively common. It is a dynamic widely viewed as a contributing factor to income inequality and intergenerational social mobility.
European fallow deer have faced a dramatic loss of genetic diversity since the last interglacial period. This was revealed by 120,000-year-old fossils from central Germany's Neumark-Nord site in Saxony-Anhalt, analyzed by researchers from the University of Potsdam, the MONREPOS
When you picture a cave, you probably think of an environment devoid of life. But for most caves on Earth, this couldn't be further from the truth.
Industrial-scale mining in Africa to support global supply chains is leading to unprecedented deforestation across the continent, with 34 hectares of forest removed for every single hectare of active mine site.
The classical drug discovery paradigm begins with a known molecular target: a protein whose modulation is expected to reverse the course of a disease. However, in many pathologies, such a target does not always exist or is not sufficiently characterized.
Chloromethane is a gas that is toxic to humans and contributes to the depletion of the ozone layer. It is produced during the combustion of coal, biomass and other raw materials. Natural sources such as algae, plants and fungi also release it. A research team led by biologist
