Forever chemical pollution can now be tracked      (via sciencedaily.com)     Original source 

Researchers developed a way to fingerprint organofluorine compounds -- sometimes called 'forever chemicals' --which could help authorities trace them to their source when they end up in aquifers, waterways or soil.

Water delivered to the mantle by aluminum enriched hydrated slabs?      (via sciencedaily.com)     Original source 

Researchers found a notable effect of aluminum on the sound velocities of superhydrous phase B, a dense hydrous magnesium silicate and potential host of water in the deep Earth. Their results suggest that aluminous phase B could explain seismic velocity anomalies in the Earth's mantle transition region and uppermost lower mantle.

Advanced chelators offer efficient and eco-friendly rare earth element recovery      (via sciencedaily.com)     Original source 

The world is going to need a lot of weird metals in the coming years, according to chemistry professor. But he isn't talking about lithium, cobalt or even beryllium. He's interested in dysprosium, which is so hidden in the periodic table that you'd be forgiven for thinking he made it up.

The race to discover biodiversity: 11 new marine species and a new platform for rapid species description      (via sciencedaily.com)     Original source 

A new paper describes a ground-breaking experiment that united 25 independent taxonomists from 10 countries. The initiative boasts the discovery of 11 new marine species from all over the globe, occurring at depths from 5.2 to 7081 meters. It also represents a significant step forward in accelerating the pace at which new marine species are described and published.

Carvings at ancient monument may be world's oldest calendars      (via sciencedaily.com)     Original source 

Markings on a stone pillar at a 12,000 year-old archaeological site in Turkey likely represent the world's oldest solar calendar, created as a memorial to a devastating comet strike, experts suggest.

Antarctic-wide survey of plant life to aid conservation efforts      (via sciencedaily.com)     Original source 

The first continent-wide mapping study of plant life across Antarctica reveals growth in previously uncharted areas and is set to inform conservation measures across the region. The satellite survey of mosses, lichens and algae across the continent will form a baseline for monitoring how Antarctica's vegetation responds to climate change.

Study revisits Texas seismic activity occurring before 2017, confirming connection to wastewater injection      (via sciencedaily.com)     Original source 

A new study by seismologists reexamines earthquakes in the Permian Basin that occurred before 2017 against the real-time data collected from earthquakes taking place after 2020. Results confirm that the seismicity occurring from 2009-2017 was causally linked to the underground injection of wastewater that is a byproduct of oil and gas extraction.

Greenland fossil discovery reveals increased risk of sea-level catastrophe      (via sciencedaily.com)     Original source 

Seeds, twigs, and insect parts found under two miles of ice confirm Greenland's ice sheet melted in the recent past, the first direct evidence that the center -- not just the edges -- of the two-mile-deep ice melted away in the recent geological past. The new research indicates that the giant ice sheet is more fragile than scientists had realized until the last few years -- and reveals increased risk of sea-level catastrophe in a warmer future.

Link between global warming and rising sea levels      (via sciencedaily.com)     Original source 

A new study suggests that Earth's natural forces could substantially reduce Antarctica's impact on rising sea levels, but only if carbon emissions are swiftly reduced in the coming decades. By the same token, if emissions continue on the current trajectory, Antarctic ice loss could lead to more future sea level rise than previously thought.

Cold antimatter for quantum state-resolved precision measurements      (via sciencedaily.com)     Original source 

Why does the universe contain matter and (virtually) no antimatter? Scientists have achieved an experimental breakthrough in this context. It can contribute to measuring the mass and magnetic moment of antiprotons more precisely than ever before -- and thus identify possible matter-antimatter asymmetries. They have developed a trap, which can cool individual antiprotons much more rapidly than in the past.

Scientists find a human 'fingerprint' in the upper troposphere's increasing ozone      (via sciencedaily.com)     Original source 

Scientists confirmed that much of ozone's increase in the upper troposphere is likely due to humans. A team detected a clear signal of human influence on upper tropospheric ozone trends in a 17-year satellite record starting in 2005.

Retreat of tropical glaciers foreshadows changing climate's effect on the global ice      (via sciencedaily.com)     Original source 

As they are in many places around the globe, glaciers perched high in the Andes Mountains are shrinking. Now, researchers have uncovered evidence that the high-altitude tropical ice fields are likely smaller than they've been at any time since the last ice age ended 11,700 years ago.

Tipping risks from overshooting 1.5 °C can be minimized if warming is swiftly reversed      (via sciencedaily.com)     Original source 

Current climate policies imply a high risk for tipping of critical Earth system elements, even if temperatures return to below 1.5 C of global warming after a period of overshoot. A new study indicates that this risk can be minimized if the warming is swiftly reversed. That is why reducing emissions in the current decade is crucial for the stability of the Earth systems functions, researchers write. They analyzed the tipping risks for four interconnected core climate tipping elements: the Greenland Ice Sheet, the West Antarctic Ice Sheet, the Atlantic Meridional Overturning Circulation (AMOC), and the Amazon Rainforest.
