Study shows microbial diversity differences in volcanic cones and craters
Volcanic activity alters the Earth's surface and promotes the development of new ecosystems, providing valuable models for studying soil formation processes such as microbial composition and vegetation succession. Increasing evidence suggests that so.....»»
Enzyme-inspired catalyst puts chemicals in right position to make ethers
Taking inspiration from enzymes, chemists at the University of Illinois Urbana-Champaign developed a catalyst to simplify the synthesis of ethers, key functional components of many drugs, foods, personal care items and other consumer goods. The catal.....»»
New findings in a decade-long study of enzyme catalysis
Synthetic chemistry provides an essential material basis for our clothing, food, housing, transportation, and medicine and is an important driving force for economic development. However, traditional chemical synthesis has bottleneck problems such as.....»»
Study reviews ginsenoside biosynthesis and regulation in Panax notoginseng
Panax notoginseng, a perennial herb central to traditional Chinese medicine, is celebrated for its health benefits, such as promoting blood circulation and reducing inflammation. Its key components, ginsenosides, are associated with various pharmacol.....»»
The olive tree"s blueprint: Key insights into high-quality oil production
A pivotal study has decoded the genetic basis of olive oil production, revealing a key regulatory mechanism that shapes oil biosynthesis. By mapping the olive tree's genome and metabolic pathways, researchers have identified how MYC2, a critical tran.....»»
Study links EV charging stations to increased local business activity
Countries globally are rapidly transitioning to a cleaner energy future—accelerating their push for electric vehicles alongside ambitious targets to phase out gasoline and diesel in transportation. Global electric car sales surged by around 25% in.....»»
Thanks to humans, Salish Sea waters are too noisy for resident orcas to hunt successfully
The Salish Sea—the inland coastal waters of Washington and British Columbia—is home to two unique populations of fish-eating orcas, the northern resident and the southern resident orcas. Human activity over much of the 20th century, including red.....»»
Surprising hormone-related gene activity discovered in the early larval stage of the Malabar grouper
Researchers at the Okinawa Institute of Science and Technology (OIST)'s Marine Climate Change Unit and Marine Eco-Evo-Devo Unit have highlighted patterns of gene activation during Malabar grouper larval development, revealing an unusual early peak of.....»»
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.....»»
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.....»»
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.....»»
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
