Deep inside super-Earths—rocky planets with masses between 1 and 10 times that of Earth—high pressure can cause familiar minerals to take forms rarely seen on Earth. Understanding more about the temperature and pressure conditions in which these phases are reached could help
Boreal forests and peatlands are shaped by hydrological changes caused by both human activity and natural processes. In a recent study carried out in the Evo area in southern Finland, researchers examined how forestry drainage and beaver-induced flooding have transformed the
Around 15 years ago, I created a Facebook page for my cat, Sandi. Friends thought it was weird. Today, social media accounts for cats attract millions of followers, cats travel in backpacks and strollers, and surveys consistently show that the overwhelming majority of owners
Many material properties depend on how electrons are arranged inside a material. Their distribution determines, for example, whether a material conducts electricity or displays magnetic behavior. Understanding how electrons organize themselves at the atomic scale is therefore
OpenAI released 10 AI-generated results over the weekend. Some mathematicians are unhappy with their approach
A new study analyzing the James Webb Space Telescope (JWST) spectra of more than 1,400 galaxies suggests a surprisingly small group of "leaky" galaxies was responsible for cosmic reionization. The paper outlining this work was posted to the arXiv preprint server on July 24.
Iguanodontians are a diverse group of herbivorous dinosaurs that lived from the Late Jurassic to the Late Cretaceous and had a worldwide distribution. Intercontinental dispersal events between Asia, North America and Europe played a key role in their diversification across
Investigators at Dana-Farber Cancer Institute have developed a platform for systematically discovering molecular glues that could become protein degradation drug candidates. The platform could help drug developers dramatically expand the range of disease-related proteins that
The recent confirmation of an atmosphere around a rocky exoplanet called LHS 1140b has created a wave of interest within the astronomy community. The planet orbits within the habitable zone around its parent star—a red dwarf located some 48 light-years from Earth.
Stanford researchers have shown that instruments primarily used to understand earthquakes can capture key details about hurricanes, helping meteorologists better predict how storms will evolve and intensify.
As consumers, we are constantly making choices about things like what to eat at a restaurant, what clothing to buy at a store and the type of car we'd like to purchase, and so much more. Savvy producers of such goods look to economists to help estimate what products people want
A new study led by a Duke University scientist overturns a long-held idea about how primates, including humans, came to have such large and sophisticated brains. The research finds that the dramatic expansion of the primate neocortex was driven largely by vision, not by the
The Arctic is warming at an accelerating pace. As permafrost thaws across vast areas and wildfires become more frequent, large amounts of methane (CH4) are being released. Together, these changes are reshaping the region's greenhouse gas emissions and further intensifying
Ants make up one of the most diverse groups of animals on the planet, with many species boasting remarkable physical abilities and social behaviors, and an overall species richness that far exceeds that of mammals. Various types of ants can carry up to one hundred times their
Fruit, honey and other naturally sweet foods may have helped fuel the evolution of the human brain, according to new research from the University of Sydney and the University of Glasgow.
