Published Fall snow levels can predict a season's total snowpack in some western states
(via sciencedaily.com) Original source Research found that, in some western states, the amount of snow already on the ground by the end of December is a good predictor of how much total snow that area will get.
Published Hot summer air turns into drinking water with new gel device
(via sciencedaily.com) Researchers have focused on the moisture present in the air as a potential source of drinking water for drought-stressed populations. They reached a significant breakthrough in their efforts to create drinkable water out of thin air: a molecularly engineered hydrogel that can create clean water using just the energy from sunlight.
Published Helicopter-based observations uncover warm ocean water flows toward Totten Ice Shelf in Southeast Antarctica
(via sciencedaily.com) Original source An international team of scientists has successfully conducted large-scale helicopter-based observations along the coast of East Antarctica and has identified pathways through which warm ocean water flows from the open ocean into ice shelf cavities for the first time.
Published Scientific ocean drilling discovers dynamic carbon cycling in the ultra-deep-water Japan Trench
(via sciencedaily.com) Original source Hadal trenches, with their deepest locations situated in the so-called hadal zone, the deepest parts of the ocean in water depth >6km, are the least-explored environment on Earth, linking the Earth's surface and its deeper interior. An international team conducting deep-subsurface sampling in a hadal trench at high spatial resolution has revealed exciting insights on the carbon cycling in the trench sediment.
Published Hybrid catalyst produces critical fertilizer and cleans wastewater
(via sciencedaily.com) Original source Synthetically produced fertilizer urea supports half of global population. Using pure metals, researchers develop hybrid catalyst with capacity to convert waste nitrogen and carbon dioxide to urea. The process could denitrify wastewater and runoff while creating a new revenue stream for water treatment facilities.
Published Water world? Methane, carbon dioxide in atmosphere of massive exoplanet
(via sciencedaily.com) A new investigation with NASA's James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. Webb's discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.
Published New insights into neutrino interactions
(via sciencedaily.com) Original source Elusive fundamental particles called neutrinos are predicted to interact unexpectedly with photons under extreme conditions.
Published Floating sea farms: A solution to feed the world and ensure fresh water by 2050
(via sciencedaily.com) Original source The sun and the sea -- both abundant and free -- are being harnessed in a unique project to create vertical sea farms floating on the ocean that can produce fresh water for drinking and agriculture.
Published Climate change can alter the risk of succumbing to infectious diseases
(via sciencedaily.com) Original source A new Europe-wide study investigated the prevalence of protozoans, bacteria and viruses potentially pathogenic to humans and domestic animals in birds and bats in varying climatic conditions. The prevalence of many of these pathogens was associated with temperature or rainfall.
Published Study reveals human destruction of global floodplains
(via sciencedaily.com) Original source A hydrologist's study provides a global estimate of human destruction of natural floodplains. The study can help guide future development in a way that can restore and conserve vital floodplain habitats that are critical to wildlife, water quality and reducing flood risk for people.
Published Study hints at the existence of the closest black holes to Earth in the Hyades star cluster
(via sciencedaily.com) A new article hints at the existence of several black holes in the Hyades cluster -- the closest open cluster to our solar system -- which would make them the closest black holes to Earth ever detected.
Published Beaver activity in the Arctic increases emission of methane greenhouse gas
(via sciencedaily.com) Original source The climate-driven advance of beavers into the Arctic tundra is causing the release of more methane -- a greenhouse gas -- into the atmosphere. Beavers, as everyone knows, like to make dams. Those dams cause flooding, which inundates vegetation and turns Arctic streams and creeks into a series of ponds. Those beaver ponds and surrounding inundated vegetation can be devoid of oxygen and rich with organic sediment, which releases methane as the material decays.
Published New bio-based glues form adhesive bonds that grow stronger in water
(via sciencedaily.com) Patent-pending adhesive formulations developed from fully sustainable, bio-based components establish bonds that grow stronger when underwater or exposed to wet conditions.
Published Ravenous black hole consumes three Earths'-worth of star every time it passes
(via sciencedaily.com) Massive burst of X-rays detected by astronomers indicates material three times the mass of Earth burning up in a black hole. They observed a star like our own Sun being eaten away every time it orbits close. First time a Sun-like star being repeatedly disrupted by a low mass black hole has been seen, opening the possibility of a range of star and black hole combinations to be discovered.
Published Revolutionizing lithium production on a string
(via sciencedaily.com) Researchers have developed a new approach that slashes the land and time needed to extract lithium from brine, which could dramatically expand access to the critical mineral.
Published Bursting air bubbles may play a key role in how glacier ice melts
(via sciencedaily.com) Original source New research has uncovered a possible clue as to why glaciers that terminate at the sea are retreating at unprecedented rates: the bursting of tiny, pressurized bubbles in underwater ice.
Published New cosmological constraints on the nature of dark matter
(via sciencedaily.com) New research has revealed the distribution of dark matter in never before seen detail, down to a scale of 30,000 light-years. The observed distribution fluctuations provide better constraints on the nature of dark matter.
Published Stability inspection for West Antarctica shows: marine ice sheet is not destabilized yet, but possibly on a path to tipping
(via sciencedaily.com) Original source Antarctica's vast ice masses seem far away, yet they store enough water to raise global sea levels by several meters. A team of experts has now provided the first systematic stability inspection of the ice sheet's current state. Their diagnosis: While they found no indication of irreversible, self-reinforcing retreat of the ice sheet in West Antarctica yet, global warming to date could already be enough to trigger the slow but certain loss of ice over the next hundreds to thousands of years.
Published New battery holds promise for green energy
(via sciencedaily.com) A chemist envisions a future where every house is powered by renewable energy stored in batteries. He has created a new battery that could have profound implications for the large-scale energy storage needed by wind and solar farms.
Published Researchers develop highly efficient and stable photoelectrode for water splitting using organic semiconductors
(via sciencedaily.com) A recent study has unveiled a significant breakthrough in photoelectrode development.
