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 Towards efficient lithium--air batteries with solution plasma-based synthesis of perovskite hydroxide catalysts
(via sciencedaily.com) Original source CoSn(OH)6 (CSO) is an effective oxygen evolution reaction (OER) catalyst, necessary for developing next-generation lithium -- air batteries. However, current methods of synthesizing CSO are complicated and slow. Recently, an international research team synthesized CSO in a single step within 20 minutes using solution plasma to generate CSO nanocrystals with excellent OER catalytic properties. Their findings could boost the manufacturing of high energy density batteries.
Published How coral reefs can survive climate change
(via sciencedaily.com) Original source Similar to the expeditions of a hundred or two hundred years ago, the Tara Pacific expedition lasted over two years. The goal: to research the conditions for life and survival of corals. The ship crossed the entire Pacific Ocean, assembling the largest genetic inventory conducted in any marine system to date. The team's 70 scientists from eight countries took around 58,000 samples from the hundred coral reefs studied.
Published Lessons in sustainability, evolution and human adaptation -- courtesy of the Holocene
(via sciencedaily.com) Original source The El Gigante rockshelter in western Honduras is among only a handful of archaeological sites in the Americas that contain well-preserved botanical remains spanning the last 11,000 years. Considered one of the most important archaeological sites discovered in Central America in the last 40 years, El Gigante was recently nominated as a UNESCO World Heritage site.
Published New study reveals global reservoirs are becoming emptier
(via sciencedaily.com) Original source Over the past two decades, global reservoirs have become increasingly empty despite an overall increase in total storage capacity due to the construction of new reservoirs. Researchers used a new approach with satellite data to estimate the storage variations of 7,245 global reservoirs from 1999 to 2018.
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 Surprise! Weaker bonds can make polymers stronger
(via sciencedaily.com) Original source Chemists discovered a new way to make polymers stronger: introduce a few weaker bonds into the material. Working with polyacrylate elastomers, they could increase the materials' resistance to tearing up to tenfold by using a weaker type of crosslinker to join some of the polymer building blocks.
Published Sinking seamount offers clues to slow motion earthquakes
(via sciencedaily.com) Original source The first ever 3D seismic imaging of a subducting seamount shows a previously unknown sediment trail in Earth's crust off the coast of New Zealand. Scientists think the sediment patches help release tectonic pressure gradually in slow slip earthquakes instead of violent tremors. The findings will help researchers search for similar patterns at other subduction zones like Cascadia in the U.S. Pacific Northwest.
Published Making the most of minuscule metal mandalas
(via sciencedaily.com) Original source To unveil the previously elusive behavior and stability of complex metal compounds found in aqueous solutions called 'POMs', researchers have created a speciation atlas. This achievement has the potential to drive new discoveries and advancements in fields like catalysis, medicine, and beyond.
Published Flooding tackled by helping citizens take action
(via sciencedaily.com) Original source Scientists have developed a new method that empowers citizens to identify solutions to climate change threats.
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 Antarctic ice shelves experienced only minor changes in surface melt since 1980
(via sciencedaily.com) Original source A team of glaciologists set out to quantify how much ice melt occurred on Antarctica's ice shelves from 1980 to 2021. The results might seem to be good news for the region, but the researchers say there's no cause for celebration just yet.
Published Biodegradable gel shows promise for cartilage regeneration
(via sciencedaily.com) Original source A gel that combines both stiffness and toughness is a step forward in the bid to create biodegradable implants for joint injuries, according to new research. Mimicking articular cartilage, found in our knee and hip joints, is challenging. This cartilage is key to smooth joint movement, and damage to it can cause pain, reduce function, and lead to arthritis. One potential solution is to implant artificial scaffolds made of proteins that help the cartilage regenerate itself as the scaffold biodegrades. How well the cartilage regenerates is linked to how well a scaffold can mimic the biological properties of cartilage, and to date, researchers have struggled to combine the seemingly incompatible properties of stiffness and toughness. Now, new research outlines a method to marry these properties in a biodegradable gel.
Published Drug-resistant fungi are thriving in even the most remote regions of Earth
(via sciencedaily.com) Original source New research has found that a disease-causing fungus -- collected from one of the most remote regions in the world -- is resistant to a common antifungal medicine used to treat infections.
Published Caribbean seagrasses provide services worth $255B annually, including vast carbon storage, study shows
(via sciencedaily.com) Original source Caribbean seagrasses provide about $255 billion in services to society annually, including $88.3 billion in carbon storage, according to a new study. The study has put a dollar value on the many services -- from storm protection to fish habitat to carbon storage -- provided by seagrasses across the Caribbean, which holds up to half the world's seagrass meadows by surface area and contains about one-third of the carbon stored in seagrasses worldwide.
Published Scientists unearth 20 million years of 'hot spot' magmatism under Cocos plate
(via sciencedaily.com) Original source A team of scientists has observed past episodic intraplate magmatism and corroborated the existence of a partial melt channel at the base of the Cocos Plate. Situated 60 kilometers beneath the Pacific Ocean floor, the magma channel covers more than 100,000 square kilometers, and originated from the Galápagos Plume more than 20 million years ago, supplying melt for multiple magmatic events -- and persisting today.
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 A Tongan volcano plume produced the most intense lightning rates ever detected
(via sciencedaily.com) Original source New research showed that the plume emitted by the Hunga Volcano eruption in 2022 created the highest lightning flash rates ever recorded on Earth, more than any storm ever documented.
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.
