Tectonic activity on this exoplanet could mean one half is covered in volcanoes
Global tectonic activity has never been observed on a planet outside our solar system, but now a new study suggests that exoplanet LHS 3844b has interior flows......»»
The case for adding iron to the ocean for carbon dioxide removal
While the urgent reduction of carbon dioxide (CO2) and other greenhouse gas emissions is needed as the primary activity to curb climate change, there is broad agreement for the need to remove CO2 already in the atmosphere. Given its outsized role in.....»»
Theoretical model for multisite alloy catalyst design quantifies active site contributions
Two research teams have developed a novel theoretical model to describe the overall activity of multisite alloy catalysts. In their study published in Journal of the American Chemical Society, they propose a concept of equivalent site ratio and succe.....»»
The moon had surprisingly recent volcanic activity, samples from Chinese space mission confirm
Volcanoes were erupting on the moon as recently as 120 million years ago, evidence collected by a Chinese spacecraft suggests. Until the last few years, scientists had thought volcanic activity ended on the moon around 2 billion years ago......»»
How context-specific factors control gene activity
Every cell in our body contains the same DNA, yet liver cells are different from brain cells, and skin cells differ from muscle cells. What determines these differences? It all comes down to gene regulation; essentially how and when genes are turned.....»»
New Mo carbide catalysts show high stability and activity in CO₂ conversion
Molybdenum (Mo) carbides, known for their unique electronic and structural properties, are considered promising alternatives to noble metal catalysts in heterogeneous catalysis. However, traditional methods for preparing Mo carbides suffer from compl.....»»
Tiny glass beads suggest the moon had active volcanoes when dinosaurs roamed Earth
Volcanoes were still erupting on the moon when dinosaurs roamed Earth, new research suggests......»»
AI shines a new light on exoplanets
Researchers from LMU, the ORIGINS Excellence Cluster, the Max Planck Institute for Extraterrestrial Physics (MPE), and the ORIGINS Data Science Lab (ODSL) have made an important breakthrough in the analysis of exoplanet atmospheres......»»
Witness 1.8 billion years of tectonic plates dance across Earth"s surface in a new animation
Using information from inside the rocks on Earth's surface, we have reconstructed the plate tectonics of the planet over the last 1.8 billion years......»»
The Moon had volcanic activity much more recently than we knew
Eruptions seem to have continued long after widespread volcanism had ended. Enlarge / The eruptions that produced the dark mare on the lunar surface ended billions of years ago. (credit: NASA/GSFC/Arizona State University).....»»
Researchers prove 120-million-year-old volcanism on moon
Extensive geologic evidence of ancient volcanic activity can be found on the moon, but how long this volcanism persisted has been unclear. However, Prof. Li Qiuli's Lab at the Institute of Geology and Geophysics of the Chinese Academy of Sciences (IG.....»»
More water worlds than we thought might support life
Too much water on exoplanet surfaces would mean high pressure ices, not life. Enlarge / High pressure ices near the crust are a feature of water-rich worlds.` (credit: Benoit Gougeon (University of Montreal)) The possibi.....»»
For many animals sleep is a social activity, but the interconnections are not fully understood
Group sleeping can impact when animals sleep, how long they sleep for, and how deeply they sleep. For example, groups of meerkats time their sleep according to "sleep traditions"; olive baboons sleep less when their group size increases; bumblebees s.....»»
Astronomers discover iron winds on an ultra-hot exoplanet
An international team of astronomers, including scientists from the University of Geneva (UNIGE) and the PlanetS National Center of Competence in Research, has identified the presence of iron winds in the atmosphere of the ultra-hot Jupiter WASP-76 b.....»»
A space oddity—small exoplanet challenges existing theories on planet formation
A research team led by Lund University in Sweden has discovered a small planet that displays peculiar orbital motion. The shimmying planet, located 455 light-years from Earth, shows that planetary systems can be considerably more complex than researc.....»»
Beef industry can reduce emissions by up to 30%, says new research
Greenhouse gases resulting from human activity have been the largest driver of climate change since the mid-20th century—especially from agriculture. The U.S. beef industry alone is responsible for 3.3% of the nation's total emissions, and even wit.....»»
Why do typhoons like to cluster? Researchers identify key weather patterns
This August, Japan and South Korea, particularly Japan, have experienced a dramatic surge in typhoon activity. From August 8 to August 13, within just six days, Typhoons Maria, Son-Tinh, Ampil, and Wukong consecutively formed over the waters east of.....»»
Researchers say 40% of UK seabird species are in trouble—bird flu, climate change, overfishing to blame
A visit to a seabird colony in summer is an assault on the senses. First there's the noise, then the overwhelming ammonia smell that stains the memory, and then the swirl of color and activity on the white-washed cliffs......»»
How vegetation could impact the climate of exoplanets
The term "habitable zone" is a broad definition that serves a purpose in our age of exoplanet discovery. But the more we learn about exoplanets, the more we need a more nuanced definition of habitable......»»
Why every island"s wildlife ends up looking alike
Located to the east of Madagascar, the bountiful, volcanic French island of Réunion has sometimes been called a sister to Hawaiian volcanoes because of the similarity in their climate and geographical nature. Those familiar with its seemingly pristi.....»»
Understanding how human activity impacts zooplankton is essential for managing and protecting lakewater
Freshwater ecosystems are impacted by human activities, including climate change, pollution and invasive species......»»
