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 Scientists discover molten layer covering Martian core
(via sciencedaily.com) Original source NASA's InSight mission to Mars helped scientists map out Mars' internal structure, including the size and composition of its core, and provided general hints about its tumultuous formation. But findings from a new paper could lead to reanalysis of that data. An international team of researchers discovered the presence of a molten silicate layer overlying Mars' metallic core -- providing new insights into how Mars formed, evolved and became the barren planet it is today.
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 Solar farms in space are possible
(via sciencedaily.com) Original source It's viable to produce low-cost, lightweight solar panels that can generate energy in space, according to new research.
Published Astrophysicists scan the Galaxy for signs of life
(via sciencedaily.com) Original source Astrophysicists are scanning the Universe for 'technosignatures' emanating from distant planets that would provide support for the existence of intelligent, alien life. Researchers plan to monitor millions of star systems.
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 Curiosity rover finds new evidence of ancient Mars rivers, a key signal for life
(via sciencedaily.com) Original source New analysis of data from the Curiosity rover reveals that much of the craters on Mars today could have once been habitable rivers.
Published Researchers capture first images of a radio 'ring of fire' solar eclipse
(via sciencedaily.com) Original source Researchers have recorded images of a solar eclipse with the 'ring of fire' effect in radio waves.
Published Superdeep diamonds provide a window on supercontinent growth
(via sciencedaily.com) Original source Diamonds contain evidence of the mantle rocks that helped buoy and grow the ancient supercontinent Gondwana from below, according to new research. These findings demonstrate that superdeep diamonds can provide a window through space and time into the supercontinent growth and formation process.
Published Researchers probe molten rock to crack Earth's deepest secrets
(via sciencedaily.com) Original source An international team re-created molten rock conditions deep within the Earth and measured the spin states of iron atoms within that rock melt. An iron atom's spin state drives its magnetic behavior and reactivity in chemical reactions, and can influence whether iron prefers to be in the molten or solid rock.
Published Researchers probe how a piece of the moon became a near-Earth asteroid
(via sciencedaily.com) Original source Two years after the striking discovery that a near-Earth asteroid could be a chunk of the moon, another UArizona research group has found that a rare pathway could have enabled this to happen.
Published Climate is increasing risk of high toxin concentrations in Northern US lakes
(via sciencedaily.com) Original source As climate change warms the Earth, higher-latitude regions will be at greater risk for toxins produced by algal blooms, according to new research. The findings identify water temperatures of 20 to 25 degrees Celsius (68 to 77 degrees Fahrenheit) as being at the greatest risk for developing dangerous levels of a common algae-produced toxin called microcystin.
Published The Moon is 40 million years older than previously thought
(via sciencedaily.com) Original source By analyzing tiny lunar crystals gathered by Apollo 17 astronauts in 1972, researchers recalculated the age of the Earth's Moon. Although previous assessments estimated the Moon as 4.425 billion years old, the new study discovered it is actually 4.46 billion years old -- 40 million years older than previously thought.
Published Land use: Producing more food and storing more carbon
(via sciencedaily.com) Original source Doubling food production, saving water, and increasing carbon storage capacity -- this may sound paradoxical, but would be theoretically feasible considering the biophysical potential of the Earth. Reaching this goal, however, would require a radical spatial reorganization of land use.
Published NASA's Webb discovers new feature in Jupiter's atmosphere
(via sciencedaily.com) Original source NASA's James Webb Space Telescope has discovered a new, never-before-seen feature in Jupiter's atmosphere. The high-speed jet stream, which spans more than 3,000 miles (4,800 kilometers) wide, sits over Jupiter's equator above the main cloud decks. The discovery of this jet is giving insights into how the layers of Jupiter's famously turbulent atmosphere interact with each other, and how Webb is uniquely capable of tracking those features.
Published New extremes in stratospheric water vapor
(via sciencedaily.com) Original source The focus of new research was to determine how deep, how much and how frequently water in the stratosphere was being increased by thunderstorms.
Published Scientists discover deepest known evidence of coral reef bleaching
(via sciencedaily.com) Original source Scientists have discovered the deepest known evidence of coral reef bleaching, more than 90 metres below the surface of the Indian Ocean. Identified during a research cruise, the damage to the deeper reefs in the Central Indian Ocean has been attributed to significant changes in the region's ocean temperature caused by the Indian Ocean Dipole. The researchers have also warned such incidences are only likely to increase as a result of present and future climate change.
