Published Archaea in a warming climate become less diverse, more predictable
(via sciencedaily.com) Original source Using a long-term multifactor experimental field site researchers showed that experimental warming of a tallgrass prairie ecosystem significantly altered the community structure of soil archaea and reduced their taxonomic and phylogenetic diversity.
Published How seaweed has been misleading scientists about reef health
(via sciencedaily.com) Original source For decades, scientists have used the amount of seaweed at the ocean's surface as a proxy for the health of coral reefs below. However, a new global study of more than 1,200 marine locations over a 16-year period reveals that this approach has been misleading -- and may even have hidden signs of reef stress.
Published Vanishing glaciers threaten alpine biodiversity
(via sciencedaily.com) Original source With glaciers melting at unprecedented rates due to climate change, invertebrates that live in the cold meltwater rivers of the European Alps will face widespread habitat loss, warn researchers. Many of the species are likely to become restricted to cold habitats that will only persist higher in the mountains, and these areas are also likely to see pressures from the skiing and tourism industries or from the development of hydroelectric plants.
Published Indo-Pacific corals more resilient to climate change than Atlantic corals
(via sciencedaily.com) Original source In the face of global warming and other environmental changes, corals in the Atlantic Ocean have declined precipitously in recent years, while corals in the Pacific and Indian Oceans are faring better. By describing several species of symbiotic algae that these corals need to grow, an international team has found that these mutualistic relationships from the Indo-Pacific may be more flexible and ultimately resilient to higher ocean temperatures than those in the Atlantic.
Published 'Gluing' soft materials without glue
(via sciencedaily.com) Original source If you're a fan of arts and crafts, you're likely familiar with the messy, sticky, frustration-inducing nature of liquid glues. But researchers now have a brand-new way to weld squishy stuff together without the need for glue at all. They've demonstrated a universal, 'electroadhesion' technique that can adhere soft materials to each other just by running electricity through them.
Published Engineers tap into good vibrations to power the Internet of Things
(via sciencedaily.com) Original source In a world hungry for clean energy, engineers have created a new material that converts the simple mechanical vibrations all around us into electricity to power sensors in everything from pacemakers to spacecraft.
Published Self-folding origami machines powered by chemical reaction
(via sciencedaily.com) Original source Scientists have harnessed chemical reactions to make microscale origami machines self-fold -- freeing them from the liquids in which they usually function, so they can operate in dry environments and at room temperature.
Published Fossil find in California shakes up the natural history of cycad plants
(via sciencedaily.com) Original source According to researchers, a new analysis of an 80-million-year-old permineralized pollen cone found in the Campanian Holz Shale formation located in Silverado Canyon, California, offers a more accurate cycad natural history -- one where the plants diversified during the Cretaceous.
Published 'Zero plant extinction' is possible, says plant ecologist
(via sciencedaily.com) Original source Like animals, many plant species are struggling to adapt to a human-dominated planet. However, plants are often overlooked in conservation efforts, even though they are cheaper and easier to protect than animals and play a pivotal role in bolstering our food, fuel, and medical systems. A plant ecologist suggests an approach for preventing all future land plant extinctions across the globe which includes training more plant experts, building an online 'metaherbarium,' and creating 'microreserves.'
Published Quantum entanglement of photons doubles microscope resolution
(via sciencedaily.com) Original source Using a "spooky" phenomenon of quantum physics, researchers have discovered a way to double the resolution of light microscopes.
Published Prolonged power outages, often caused by weather events, hit some parts of the U.S. harder than others
(via sciencedaily.com) Original source New research found that Americans already bearing the brunt of climate change and health inequities are most at risk of impact by a lengthy power outage.
Published Machine learning helps scientists identify the environmental preferences of microbes
(via sciencedaily.com) Original source A machine-learning approach can give scientists insight into the environmental preferences of microbes, based only on their genes. The approach has practical research implications: it could help researchers more efficiently grow bacteria in the laboratory. It could also lead to smarter use of microbes in agriculture, ecological restoration, and even probiotics.
Published Previously unknown intercellular electricity may power biology
(via sciencedaily.com) Original source Researchers have discovered that the electrical fields and activity that exist through a cell's membrane also exist within and around another type of cellular structure called biological condensates. Like oil droplets floating in water, these structures exist because of differences in density. Their foundational discovery could change the way researchers think about biological chemistry. It could also provide a clue as to how the first life on Earth harnessed the energy needed to arise.
Published New research redefines mammalian tree of life
(via sciencedaily.com) Original source Scientists from around the globe are using the largest mammalian genomic dataset in history to determine the evolutionary history of the human genome in the context of mammalian evolutionary history. Their ultimate goal is to better identify the genetic basis for traits and diseases in people and other species.
Published Ecosystem evolution in Africa
(via sciencedaily.com) Original source New research pushes back the oldest evidence of C4 grass-dominated habitats in Africa -- and globally -- by more than 10 million years, with important implications for primate evolution and the origins of tropical C4 grasslands and savanna ecosystems across the African continent and around the world.
Published The reasons why insect numbers are decreasing
(via sciencedaily.com) Original source Researchers are investigating the causes and consequences of the worldwide insect decline as well as considering potential countermeasures.
Published Early-nesting ducks at increased risk due to changes in climate, land use
(via sciencedaily.com) Original source Each year approximately 10 million waterfowl fly north to their breeding grounds in the Prairie Pothole Region of North America, but the landscape that greets them has changed. Weather patterns and agricultural practices have significantly transformed the pothole-dotted native grasslands that waterfowl have used for thousands of years.
Published Elephant ecosystems in decline
(via sciencedaily.com) Original source Global space for Asian elephant habitats has been in rapid decline since the 1700s, a new report reveals. More than 3 million square kilometers of the Asian elephant's historic habitat range has been lost in just three centuries and may underlie present-day conflicts between elephants and people.
Published Ant mounds are more important for biodiversity than previously thought
(via sciencedaily.com) Original source The ant mounds on the heath, in the forest and in your garden are oases for life. The heat and nutrients from ant mounds make them the perfect home for unique plant and animal species, according to new research.
Published Researchers explore techniques to successfully reintroduce captive birds into the wild
(via sciencedaily.com) Original source Studies show that some species may require breeding in captivity within the next 200 years to avoid extinction. This reality places heavy importance on the reintroduction practices used to successfully transfer species from captivity to the wild. A new study looks at some of the most popular conservation techniques and identifies which have the highest likelihood of success for the reintroduction of bird species back into the wild.
