Published Past climate warming driven by hydrothermal vents
(via sciencedaily.com)
Original source 
An international drilling expedition off the Norwegian coast confirms the theory that methane emissions from hydrothermal vents were responsible for global warming about 55 million years ago. The study shows that the vents were active in very shallow water depth or even above sea level, which would have allowed much larger amounts of methane to enter the atmosphere.
Published New photocatalytic system converts carbon dioxide to valuable fuel more efficiently than natural photosynthesis
(via sciencedaily.com) 
A research team recently developed a stable artificial photocatalytic system that is more efficient than natural photosynthesis. The new system mimics a natural chloroplast to convert carbon dioxide in water into methane, a valuable fuel, very efficiently using light. This is a promising discovery, which could contribute to the goal of carbon neutrality.

Published Sensing and controlling microscopic spin density in materials
(via sciencedaily.com) 
Researchers found a way to tune the spin density in diamond by applying an external laser or microwave beam. The finding could open new possibilities for advanced quantum devices.
Published Nanorings: New building blocks for chemistry
(via sciencedaily.com) 
Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear. Recently, researchers made stacked sandwich complexes form a nano-sized ring. Physical and other properties of these cyclocene structures will now be further investigated.
Published Study highlights importance of mineral iron in ocean ecosystems
(via sciencedaily.com)
Original source 
New research has revealed the importance of mineral forms of iron in regulating the cycling of this bio-essential nutrient in the ocean. The findings pave the way for new work on the relationship between the iron and carbon cycles and how changing ocean oxygen levels may interact.
Published Sustainable mobility planning supported by doughnut thinking
(via sciencedaily.com)
Original source 
A new scientific article shows how the donut model, which examines the overall sustainability of societies, can be applied to transport.
Published Butterfly-inspired films create vibrant colors while passively cooling objects
(via sciencedaily.com)
Original source 
New films inspired by butterfly wings circumvent the heating effect usually experienced by colored objects absorbing light on a hot day. The new films could be used on the outside of buildings, vehicles and equipment to reduce the energy needed for cooling while preserving vivid color properties.
Published New research casts doubt on role of fungus in driving pancreatic cancer
(via sciencedaily.com)
Original source 
Four years ago, a report that a common species of fungus might fuel pancreatic cancer offered a promising new view of the deadly disease. But in working to validate the finding, researchers have found no such association.
Published Robots cause company profits to fall -- at least at first
(via sciencedaily.com) 
Researchers have found that robots can have a 'U-shaped' effect on profits: causing profit margins to fall at first, before eventually rising again. The researchers studied industry data from the UK and 24 other European countries between 1995 and 2017, and found that at low levels of adoption, robots have a negative effect on profit margins. But at higher levels of adoption, robots can help increase profits.
Published Researchers are using monkey poop to learn how an endangered species chooses its mates
(via sciencedaily.com)
Original source 
Northern muriquis, which live in the Atlantic forest of Brazil, are one of the most endangered species of monkey in the world. To better understand what goes on in the mating lives of muriquis, researchers turned to the monkeys' poop to help gain insight into how the primates choose their mates.
Published Scientists dig into wildfire predictions, long-term impacts
(via sciencedaily.com)
Original source 
Wildfires are an ancient force shaping the environment, but they have grown in frequency, range and intensity in response to a changing climate. Scientists are working on several fronts to better understand and predict these events and what they mean for the carbon cycle and biodiversity.
Published Sea urchins are struggling to 'get a grip' as climate change alters ecosystems
(via sciencedaily.com)
Original source 
As global climate change causes weather extremes ranging from heat waves and droughts to heavy rains and flooding, the large amounts of freshwater pouring into nearshore ecosystems are altering habitats. A team of biologists studied the impacts of low salinity and how it alters sea urchins' ability to grip and move within their habitat.
Published Quantum discovery: Materials can host D-wave effects with F-wave behaviors
(via sciencedaily.com) 
In a potential boon for quantum computing, physicists have shown that topologically protected quantum states can be entangled with other, highly manipulable quantum states in some electronic materials.
Published Super Radar: Breakthrough radar research overcomes a nearly century-old trade-off between wavelength and distance resolution
(via sciencedaily.com) 
New interference radar functions improve the distance resolution between objects using radar waves. The results may have important ramifications in military, construction, archaeology, mineralogy and many other domains of radar applications. It addresses a nine decades-old problem that requires scientists and engineers to sacrifice detail and resolution for observation distance -- underwater, underground, and in the air.
Published The history and future of ancient einkorn wheat Is written in its genes
(via sciencedaily.com)
Original source 
Researchers have sequenced the complete genome for einkorn wheat, the world's first domesticated crop and traced its evolutionary history. The information will help researchers identify genetic traits like tolerance to diseases, drought and heat, and re-introduce those traits to modern bread wheat.
Published Robotic grippers offer unprecedented combo of strength and delicacy
(via sciencedaily.com) 
New robotic grippers are flexible enough to handle soft and fragile objects as well as heavier ones.
Published New method simplifies the construction process for complex materials
(via sciencedaily.com) 
A new technique incorporates many different building blocks of cellular metamaterials into one unified graph-based representation. This can be used to make a user-friendly interface that can quickly and easily model metamaterials, edit the structures, and simulate their properties.
Published Gravitational arcs in 'El Gordo' galaxy cluster
(via sciencedaily.com) 
A new image of the galaxy cluster known as 'El Gordo' is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope images.
Published Nature's kitchen: how a chemical reaction used by cooks helped create life on Earth
(via sciencedaily.com)
Original source 
A chemical process used in the browning of food to give it its distinct smell and taste is probably happening deep in the oceans, where it helped create the conditions necessary for life. Known as the Maillard reaction after the French scientist who discovered it, the process converts small molecules of organic carbon into bigger molecules known as polymers. In the kitchen, it is used to create flavors and aromas out of sugars. But a research team argues that on the sea floor, the process has had a more fundamental effect, where it has helped to raise oxygen and reduce carbon dioxide levels in the atmosphere, to create the conditions for complex life forms to emerge and thrive on Earth.
