Published Shifting nesting timing not enough to prevent fewer sea turtle hatchlings
(via sciencedaily.com) Original source New research shows that potential adaptive responses by sea turtles, such as shifting the timing of when they nest, may not be enough to counteract the projected impacts from climate change on hatchling production.
Published Humans are disrupting natural 'salt cycle' on a global scale, new study shows
(via sciencedaily.com) Original source A new paper revealed that human activities are making Earth's air, soil and freshwater saltier, which could pose an 'existential threat' if current trends continue. Geologic and hydrologic processes bring salts to Earth's surface over time, but human activities such as mining and land development are rapidly accelerating this natural 'salt cycle.'
Published Amazon deforestation linked to long distance climate warming
(via sciencedaily.com) Original source Deforestation in the Amazon causes land surfaces up to 100 kilometers away to get warmer, suggests a new study. The research suggests that tropical forests play a critical role in cooling the land surface -- and that effect can play out over considerable distances.
Published Study uncovers hundred-year lifespans for three freshwater fish species in the Arizona desert
(via sciencedaily.com) Original source New study finds some of the oldest animals in the world living in a place you wouldn't expect: fishes in the Arizona desert.
Published Offset markets: New approach could help save tropical forests by restoring faith in carbon credits
(via sciencedaily.com) Original source A new approach to valuing the carbon storage potential of natural habitats aims to help restore faith in offset schemes, by enabling investors to directly compare carbon credit pricing across a wide range of projects.
Published New species of mosasaur named for Norse sea serpent
(via sciencedaily.com) Original source Scientists have discovered a new species of mosasaur, large, carnivorous aquatic lizards that lived during the late Cretaceous. With 'transitional' traits that place it between two well-known mosasaurs, the new species is named after a sea serpent in Norse mythology, Jormungandr, and the small North Dakota city Walhalla near to where the fossil was found.
Published The importance of the Earth's atmosphere in creating the large storms that affect satellite communications
(via sciencedaily.com) Original source Large geomagnetic storms disrupt radio signals and GPS. Now, researchers have identified the previous underestimated role of the ionosphere, a region of Earth's upper atmosphere that contains a high concentration of ions and free electrons, in determining how such storms develop. Understanding the interactions that cause large geomagnetic storms is important because they can disrupt radio signals and GPS. Their findings may help predict storms with the greatest potential consequences.
Published Meltwater flowing beneath Antarctic glaciers may be accelerating their retreat
(via sciencedaily.com) Original source A new Antarctic ice sheet modeling study suggests that meltwater flowing out to sea from beneath Antarctic glaciers is making them lose ice faster.
Published Cold War spy satellite imagery reveals Ancient Roman forts
(via sciencedaily.com) Original source A new study analyzing declassified Cold War satellite imagery reveals 396 previously undocumented Roman forts and reports that these forts were constructed from east to west, spanning from what is now western Syria to northwestern Iraq. The analysis refutes Father Antoine Poidebard's claim that the forts were located along a north-south axis.
Published The race of water droplets
(via sciencedaily.com) Original source How fast does a droplet flow along a fiber? It depends on the diameter of the fiber... and also on its substructure! These are the findings of a study conducted by researchers who are interested in microfluidics, especially water harvesting in arid/semi-arid regions of our planet.
Published Alpine rock reveals dynamics of plate movements in Earth's interior
(via sciencedaily.com) Original source Examining how plates move in Earth's mantle and how mountains form is no easy feat. Certain rocks that have sunk deep into Earth's interior and then returned from there can deliver answers.
Published Venus had Earth-like plate tectonics billions of years ago, study suggests
(via sciencedaily.com) Original source Venus, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. The finding sets up tantalizing scenarios regarding the possibility of early life on Venus, its evolutionary past and the history of the solar system.
Published Algae's surprising potential to help ease climate change worries
(via sciencedaily.com) Original source The key to bringing global net-zero goals into reach may be algae, say researchers. Studies show impressive success of certain microalgae varieties to remove CO2 from the atmosphere then break it down into useful materials.
Published Bizarre new fossils shed light on ancient plankton
(via sciencedaily.com) Original source Recently discovered microfossils date back half a billion years. Resembling modern-day algae, they provide insight into early life in our oceans.
Published Biological fingerprints in soil show where diamond-containing ore is buried
(via sciencedaily.com) Original source Researchers have identified buried kimberlite, the rocky home of diamonds, by testing the DNA of microbes in the surface soil. These 'biological fingerprints' can reveal what minerals are buried tens of meters below the earth's surface without having to drill. The researchers believe it is the first use of modern DNA sequencing of microbial communities in the search for buried minerals. The research represents a new tool for mineral exploration, where a full toolbox could save prospectors time and a lot of money,
Published Adding crushed rock to farmland pulls carbon out of the air
(via sciencedaily.com) Original source Adding crushed volcanic rock to farmland can pull carbon dioxide out of the air. In a field test, scientists found that the process works even in dry climates.
Published Raining cats and dogs: Global precipitation patterns a driver for animal diversity
(via sciencedaily.com) Original source A team has identified several factors to help answer a fundamental ecological question: why is there a ridiculous abundance of species some places on earth and a scarcity in others? What factors, exactly, drive animal diversity? They discovered that what an animal eats (and how that interacts with climate) shapes Earth's diversity.
Published Climate report: 'Uncharted territory' imperils life on Earth
(via sciencedaily.com) Original source An international coalition of climate scientists says that the Earth's vital signs have worsened beyond anything humans have yet seen, to the point that life on the planet is imperiled.
Published Light, freshwater sticks to Greenland's east coast
(via sciencedaily.com) Original source Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island. In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.
Published Origin of ancient mummified baboons found in Egypt
(via sciencedaily.com) Original source Primatologists are using genetic analysis to determine the geographic origin of ancient mummified baboons found in Egypt. The team finds evidence that the two legendary trading regions of Punt and Adulis may have been the same place separated by a thousand years of history.
