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 Gray whales off Oregon Coast consume millions of microparticles per day
(via sciencedaily.com)
Original source 
Researchers estimate that gray whales feeding off the Oregon Coast consume up to 21 million microparticles per day, a finding informed in part by feces from the whales.
Published 'Toggle switch' can help quantum computers cut through the noise
(via sciencedaily.com)
Original source 
What good is a powerful computer if you can't read its output? Or readily reprogram it to do different jobs? People who design quantum computers face these challenges, and a new device may make them easier to solve.
Published Ancient marine reptile fossil, publish ground-breaking evolutionary insight
(via sciencedaily.com)
Original source 
Researchers who have unlocked new evolutionary information following the discovery of a 94-million-year-old mosasaur in the gray shale badlands of the National Park Service Glen Canyon National Recreation Area in southern Utah.
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 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 Do hummingbirds drink alcohol? More often than you think
(via sciencedaily.com)
Original source 
Animals that eat fruit or sip nectar often ingest alcohol because naturally occurring yeasts turning sugar into ethanol. But how do animals feel about that? A new study details an experiment to determine whether hummingbirds are turned off by alcohol in sugar water. At 1% by volume, no. At 2% by volume, they consume much less. The implication is that hummingbirds have adjusted to small amounts of alcohol likely present in flowers and backyard feeders.
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 Perovskite solar cells set new record for power conversion efficiency
(via sciencedaily.com)
Original source 
Perovskite solar cells have attained now attained the extremely high efficiency rate of 24.35% with an active area of 1 cm2. This ground-breaking achievement in maximizing power generation from next-generation renewable energy sources will be crucial to securing the world's energy future.
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 Inside-out heating and ambient wind could make direct air capture cheaper and more efficient
(via sciencedaily.com)
Original source 
Chemical engineers use coated carbon fibers and eliminate steam-based heating in their simpler design, which also can be powered by wind energy.
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 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 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.
