Published First detection of heavy element from star merger
(via sciencedaily.com) Original source A team of scientists has used multiple space and ground-based telescopes to observe an exceptionally bright gamma-ray burst, GRB 230307A, and identify the neutron star merger that generated an explosion that created the burst. Webb also helped scientists detect the chemical element tellurium in the explosion's aftermath.
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 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 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 Astronomers detect most distant fast radio burst to date
(via sciencedaily.com) Original source An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Large Telescope (VLT) in a galaxy so far away that its light took eight billion years to reach us. The FRB is also one of the most energetic ever observed; in a tiny fraction of a second it released the equivalent of our Sun's total emission over 30 years.
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.
Published Black holes could come in 'perfect pairs' in an ever expanding Universe
(via sciencedaily.com) Original source Researchers have shown it's theoretically possible for black holes to exist in perfectly balanced pairs -- held in equilibrium by a cosmological force -- mimicking a single black hole.
Published New study finds 50-year trend in hurricane escalation linked to climate change
(via sciencedaily.com) Original source New research by climate scientists indicates that there have been great changes to Atlantic hurricanes in just the past 50 years, with storms developing and strengthening faster.
