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......»»
A not-so-solid lake ice season
Mountain lakes provide freshwater for roughly half the world's population. Yet a shifting climate could impact the reliability of this resource by altering the temperature patterns that govern lake conditions and influence lake biota......»»
Scientists map underwater topography of more than 1.4 million lakes and reservoirs worldwide
Lakes and reservoirs have a profound influence on ecosystem functions, local streamflow levels, and the movement of water across landscapes. But water managers often are in the dark when it comes to subsurface topography, which affects the ecology, v.....»»
Potential impacts of emerald ash borer on wildlife in black ash wetlands
Black ash wetlands cover approximately 1.2 million acres of wetland forest in the western Great Lakes. They are an ecologically significant part of Minnesota's landscapes and provide critical habitat for wildlife. .....»»
Monitoring Arctic permafrost with satellites, supercomputers, and deep learning
Permafrost—ground that has been permanently frozen for two or more years—makes up a large part of the Earth, around 15% of the Northern Hemisphere......»»
First-of-its-kind live imaging leads to major discovery in how cells pattern in tissues
The ability of cells to self-organize into specific patterns in tissues that serve a function is a universal feature of life. The stripes of a zebra, our eyelashes, the spiral of seeds in a sunflower and the maze patterns of snakeskins are just a few.....»»
Manufacturing industry needs to embrace digital transformation, says Google Cloud Taiwan director
The urgent need for digital transformation in manufacturing has been highlighted during the COVID-19 pandemic by job loss, materials shortages, cargo congestion, and changes in office and consumer patterns, according to Tony Hsieh, Taiwan country dir.....»»
Pine needles tell the story of PFAS in North Carolina
The humble pine tree is more than just a common sight in North Carolina—it's also a handy tool for monitoring the proliferation of per- and polyfluoroalkyl substances (PFAS) in our state over time......»»
The secret ultraviolet colors of sunflowers attract pollinators and preserve water
Flowers are one of the most striking examples of diversity in nature, displaying myriad combinations of colors, patterns, shapes and scents. They range from colorful tulips and daisies, to fragrant frangipani and giant, putrid-smelling corpse flowers.....»»
Grazing technique that mirrors natural patterns helps protect grasslands from drought
Ranchers who frequently rotate cattle between fields—resembling how bison once moved across Canada's prairie—build drought resistance into Western Canada's grasslands, according to a series of University of Alberta studies designed to find ways t.....»»
Soil pH drives the distribution of soil bacterial communities along a short elevational gradient
Soil microbes are highly diverse and play a key role in the regulation of biogeochemical cycling processes and the maintenance of ecosystem functions. Knowledge of the elevational distribution patterns of soil microbes and the driving mechanisms will.....»»
Heading Football and Head Impacts "Change Blood Patterns in Brain"
Repeated heading and accidental head impacts in football cause changes to blood patterns in the brain, potentially interfering with signalling pathways, according to a study of players in Norway. From a report: The peer-reviewed research, published i.....»»
Earth scientists simulate the future to model forest restoration impact
Replanting previously forested landscapes in the tropics is a nature-based solution that can play a role in removing carbon dioxide from the atmosphere, but whether those new forests will withstand the impacts of future climate change was a big uncer.....»»
Orangutans instinctively use hammers to strike and sharp stones to cut
Untrained, captive orangutans can complete two major steps in the sequence of stone tool use: striking rocks together and cutting using a sharp stone, according to a study by Alba Motes-Rodrigo at the University of Tübingen in Germany and colleagues.....»»
Lake evaporation patterns will shift with climate change
For many people, warm summer days feature spending time swimming in a lake. Lakes are important for more than just recreation and serve as a major global source of freshwater. But as temperatures continue to get warmer, so will lakes. As global avera.....»»
Nick of time: Temporal variation of light-matter interaction boosts photonic metamaterials
At the interface between two media, light is partly reflected backwards into the medium from where it came and partly transmitted into the neighboring medium, like a light ray entering a sparkling pool of water. The light wave patterns that arise fro.....»»
Growing the perfect diamond: Simulations reveal interesting geometric patterns
In today's societies, the word "diamond" brings to mind a series of images. It entails stories of strength, wealth, and status. But strip away these associations, and the scientific uses of the material are revealed. Diamonds are transparent, extreme.....»»
Solving the ice problem in cryo-electron microscopy
Cryo-EM requires protein samples to be frozen before they are imaged using an electron microscope. This revolutionary technique and its application to structural biology was the focus of the Nobel Prize for Chemistry in 2017 and has contributed to a.....»»
How El Niño and drought affected the transatlantic slave trade
El Niño, an oceanic phenomenon that affects worldwide weather patterns, significantly affected the number of enslaved Africans transported from West Africa to the Americas between the mid-1600s and mid-1800s, according to a study from the University.....»»
Trust in science rose in Germany after onset of COVID-19 pandemic
Surveys conducted in Germany suggest that public trust in science rose after the start of the COVID-19 pandemic in 2020, while revealing different patterns of trust among different subpopulations. Rainer Bromme of the University of Münster, Germany,.....»»
Immigration patterns are reflected in Facebook data on popular foods and drinks
Researchers have developed a novel strategy for using Facebook data to measure cultural similarity between countries, revealing associations between immigration patterns and people's food and drink interests. Carolina Vieira of the Max Planck Institu.....»»
