Published Study of deep-sea corals reveals ocean currents have not fuelled rise in atmospheric carbon dioxide
(via sciencedaily.com) Original source Pioneering analysis of deep-sea corals has overturned the idea that ocean currents contributed to increasing global levels of carbon dioxide in the air over the past 11,000 years.
Published First detection of crucial carbon molecule
(via sciencedaily.com) Original source Scientists detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation of more complex carbon-based molecules. Methyl cation was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula.
Published Investing in nature improves equity, boosts economy
(via sciencedaily.com) Original source A new study shows that current trends in environmental degradation will lead to large economic losses in the coming decades, hitting the poorest countries hardest. But there is hope: investing in nature can turn those losses into gains.
Published Effect of volcanic eruptions significantly underestimated in climate projections
(via sciencedaily.com) Original source Researchers have found that the cooling effect that volcanic eruptions have on Earth's surface temperature is likely underestimated by a factor of two, and potentially as much as a factor of four, in standard climate projections.
Published Are viruses keeping sea lice at bay in wild salmon?
(via sciencedaily.com) Original source More than 30 previously unknown RNA viruses in sea lice have been identified. Sea lice are parasitic copepods (small crustaceans) found in many fresh and saltwater habitats, and have been implicated in the decline of wild salmon populations. The research sheds greater light on the types of viruses being carried by sea lice, and how the viruses and host are interacting.
Published Einstein and Euler put to the test at the edge of the Universe
(via sciencedaily.com) Original source The cosmos is a unique laboratory for testing the laws of physics, in particular those of Euler and Einstein. Euler described the movements of celestial objects, while Einstein described the way in which celestial objects distort the Universe. Since the discovery of dark matter and the acceleration of the Universe's expansion, the validity of their equations has been put to the test: are they capable of explaining these mysterious phenomena? A team has developed the first method to find out. It considers a never-before-used measure: time distortion.
Published Will engineered carbon removal solve the climate crisis?
(via sciencedaily.com) Original source A new study explored fairness and feasibility in deep mitigation pathways with novel carbon dioxide removal, taking into account institutional capacity to implement mitigation measures.
Published Never-before-seen way to annihilate a star
(via sciencedaily.com) Original source Astronomers studying a powerful gamma-ray burst, may have detected a never-before-seen way to destroy a star. Unlike most GRBs, which are caused by exploding massive stars or the chance mergers of neutron stars, astronomers have concluded that this GRB came instead from the collision of stars or stellar remnants in the jam-packed environment surrounding a supermassive black hole at the core of an ancient galaxy.
Published Rain gardens could save salmon from toxic tire chemicals
(via sciencedaily.com) Original source Specially designed gardens could reduce the amount of a toxic chemical associated with tires entering our waterways by more than 90 per cent, new research shows.
Published Smart farming platform improves crop yields, minimizes pollution
(via sciencedaily.com) Original source A new farming system aims to solve one of the biggest problems in modern agriculture: the overuse of fertilizers to improve crop yields and the resulting chemical runoff that pollutes the world's air and water.
Published PFAS found in blood of dogs, horses living near Fayetteville, NC
(via sciencedaily.com) Original source Researchers detected elevated PFAS levels in the blood of pet dogs and horses from Gray's Creek, N.C. -- including dogs that only drank bottled water.
Published New study reveals irrigation's mixed effects around the world
(via sciencedaily.com) Original source Trajectory of irrigation water use in many regions is unsustainable, but practice is vital in managing climate change and future agricultural development, researchers conclude.
Published Clean, sustainable fuels made 'from thin air' and plastic waste
(via sciencedaily.com) Original source Researchers have demonstrated how carbon dioxide can be captured from industrial processes -- or even directly from the air -- and transformed into clean, sustainable fuels using just the energy from the Sun.
Published To boost supply chains, scientists are looking at ways to recover valuable materials from water
(via sciencedaily.com) Original source Researchers are exploring the different ways of harvesting materials from water.
Published Study finds combustion from gas stoves can raise indoor levels of chemical linked to a higher risk of blood cell cancers
(via sciencedaily.com) Original source About 47 million homes use natural gas or propane-burning cooktops and ovens. Researchers found that cooking with gas stoves can raise indoor levels of the carcinogen benzene above those found in secondhand smoke.
Published Researchers demystify the unusual origin of the Geminids meteor shower
(via sciencedaily.com) Original source Princeton researchers used observations from NASA's Parker Solar Probe mission to deduce that it was likely a violent, catastrophic event -- such as a high-speed collision with another body or a gaseous explosion -- that created the Geminids meteoroid stream. Mysteries surrounding the origin of the Geminids have long fascinated scientists because, while most meteor showers are created when a comet emits a tail of ice and dust, the Geminids stem from an asteroid -- a chunk of rock that normally does not produce a tail. Until now, this unusual meteoroid stream had only been studied from Earth.
Published Discovery of white dwarf pulsar sheds light on star evolution
(via sciencedaily.com) Original source The discovery of a rare type of white dwarf star system provides new understanding into stellar evolution.
Published How will a warming world impact the Earth's ability to offset our carbon emissions?
(via sciencedaily.com) Original source New work deploys a bold new approach for inferring the temperature sensitivity of ecosystem respiration -- which represents one side of the equation balancing carbon dioxide uptake and carbon dioxide output in terrestrial environments. This will improve scientists' models for climate change scenarios.
Published Massive underwater plateau near Solomon Islands is younger and its eruption was more protracted than previously thought
(via sciencedaily.com) Original source The Ontong Java Plateau, a volcanically-formed underwater plateau located in the Pacific Ocean north of the Solomon Islands, is younger and its eruption was more protracted than previously thought, new research suggests.
Published Scientists discover urea in atmosphere revealing profound consequences for climate
(via sciencedaily.com) Original source Areas of the ocean that are rich in marine life are having a bigger impact on our ecosystems and the climate than previously thought, new research suggests.
