How "ice needles" weave patterns of stones in frozen landscapes
Nature is full of repeating patterns that are part of the beauty of our world. An international team, including a researcher from the University of Washington, used modern tools to explain repeating patterns of stones that form in cold landscapes......»»
The intricate mechanisms of epigenetic silencing
Epigenetic silencing, which involves the suppression of gene activity, is a fascinating and increasingly influential branch of biological sciences. It allows cells to remember and maintain specific gene expression patterns throughout development and.....»»
Astronomers capture formation of a powerful cosmic jet
Using a network of radio telescopes on Earth and in space, astronomers have captured the most detailed view ever of a jet of plasma from a supermassive black hole. The jet travels at nearly the speed of light and shows complex, twisted patterns near.....»»
Research finds global precipitation patterns a driver for animal diversity
Since the HMS Beagle arrived in the Galapagos with Charles Darwin to meet a fateful family of finches, ecologists have struggled to understand a particularly perplexing question: Why is there a ridiculous abundance of species some places on Earth and.....»»
"Frozen in time" landscape discovered under Antarctic ice
Scientists revealed Tuesday that they had discovered a vast, hidden landscape of hills and valleys carved by ancient rivers that has been "frozen in time" under the Antarctic ice for millions of years......»»
Ancient pots hold clues about how diverse diets helped herders thrive in southern Africa
The introduction of herding—a way of life which centers on keeping herds of mobile domesticated animals—significantly changed Africa's genetic, economic, social and cultural landscapes during the last 10,000 years. Unlike other parts of the world.....»»
Researchers develop novel data representation for transcription factor-binding sequences
The diverse characteristics of the human body's various cells are reflected in their gene expression patterns. The regulation of such gene expression is based on transcription factors that bind to specific sequences in the genome......»»
Rumors of all iPhone 16 models having an A18 processor make no sense
A stock analyst has put forth the rumor that the entire iPhone 16 lineup will have an A18-branded chip, but between his track record and Apple's recent patterns, it seems unlikely at this point.The iPhone 16 Pro, maybeIn a note to investors, Analyst.....»»
El Niño"s changing patterns: Human influence on natural variability
Two recent scientific studies led by Dr. Paul Wilcox from the Department of Geology at the University of Innsbruck provide new insights into Earth's climate dynamics, with a particular focus on the El Niño phenomenon. The results show how El Niño r.....»»
Scientists present the first set of global maps showing geographic patterns of beta-diversity in flowering plants
Beta-diversity serves as a crucial metric for gauging shifts in species composition over spatial or temporal scales, bridging the spectrum between localized (alpha) and broader regional (gamma) diversity. In the fields of ecology, biogeography and co.....»»
Scientists count huge melts in many protective Antarctic ice shelves. Trillions of tons of ice lost.
Four dozen Antarctic ice shelves have shrunk by at least 30% since 1997 and 28 of those have lost more than half of their ice in that time, reports a new study that surveyed these crucial "gatekeepers'' between the frozen continent's massive glaciers.....»»
Study investigates impact of extreme weather events on ocean circulation in tropical Pacific
The strength of the wind has an important influence on ocean circulation. This is particularly true for extreme events such as storm fronts, tropical storms and cyclones. These weather patterns, which last from a few days to a few weeks, will change.....»»
Runestones reveal the power of a Viking queen
Archaeologists have used 3D scanning to investigate inscriptions carved on two groups of Danish runestones, revealing that four stones were likely made in dedication to a powerful Viking Queen......»»
Size matters: How body size shapes dogs" aging patterns
Smaller dogs may live twice as long life as their larger counterparts. But does this size difference also impact how dogs age in terms of behavior and cognitive abilities? Based on the data of 15,000 dogs, researchers from ELTE Eötvös Loránd Unive.....»»
Isotope database will help Mexican communities better understand hydrology processes
With a population of 127 million and a land mass about a fifth the size of the United States, Mexico has a large spectrum of climates and landscapes, ranging from mountains to coastal regions and from deserts to glaciers. Because of these variations,.....»»
Study shows birds disperse eaten insects" eggs
Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis of natural populations in Japan by Kobe University.....»»
Research shows COVID-19 pandemic substantially changed commuting patterns, access to jobs
Patterns of movement in cities, especially office job commutes, were substantially changed in 2021 by telework, economic change and other responses to COVID-19, according to new research from the Accessibility Observatory at the University of Minneso.....»»
Researchers find pre-Columbian agave plants persisting in Arizona landscapes
A new paper in the Annals of Botany reveals that researchers have found unaltered agave plant species cultivated by several early cultures including the Hohokam people, a large Native American group in the Southwest that existed between 300 and 1500.....»»
Scientists gain powerful tool to scrutinize changing US weather patterns
An extraordinary new dataset of high-resolution weather simulations that span more than four decades over the continental United States is now available to the Earth system science community......»»
Climate change affecting ability to prevent US wildfires: study
Shifting weather patterns caused by climate change are limiting when controlled burns can be carried out to prevent wildfires in the western United States, a new study warns......»»
How Arctic landscapes and Canadian cityscapes share a similar pattern
The year 2023 has been one of extremes, from heat waves that baked millions across the globe and made the summer the world's hottest on record to the fires that forced tens of thousands to evacuate across Western Canada. From the feel of surprising w.....»»
