Published Galaxy clusters yield new evidence for standard model of cosmology
(via sciencedaily.com) Original source A new study probing the structure and evolution of galaxy clusters shows good agreement with the predictions of standard cosmological models.
Published Innovative method predicts the effects of climate change on cold-blooded animals
(via sciencedaily.com) In the face of a warming climate that is having a profound effect on global biodiversity and will change the distribution and abundance of many animals, a research team has developed a statistical model that improves estimates of habitat suitability and extinction probability for cold-blooded animals as temperatures climb.
Published Rising temperatures alter 'missing link' of microbial processes, putting northern peatlands at risk
(via sciencedaily.com) Researchers show that rising temperatures in northern regions may damage peatlands: critical ecosystems for storing carbon from the atmosphere -- and could decouple vital processes in microbial support systems.
Published Path to net-zero carbon capture and storage may lead to ocean
(via sciencedaily.com) Engineering researchers have developed a novel way to capture carbon dioxide from the air and store it in the 'infinite sink' of the ocean. The approach uses an innovative copper-containing polymeric filter and essentially converts CO2 into sodium bicarbonate (aka baking soda) that can be released harmlessly into the ocean. This new hybrid material, or filter, is called DeCarbonHIX (i.e., decarbonization through hybrid ion exchange material). The research has demonstrated a 300 percent increase in the amount of carbon captured compared with existing direct air capture methods.
Published Ants took over the world by following flowering plants out of prehistoric forests
(via sciencedaily.com) Today, ants are pretty much everywhere. To learn more about how these insects conquered the world, scientists used a combination of fossils, DNA, and data on the habitat preferences of modern species to piece together how ants and plants have been evolving together over the past 60 million years. They found that when flowering plants spread out from forests, the ants followed, kicking off the evolution of the thousands of ant species alive today.
Published At the end of the dry season: CO2 pulses over Australia
(via sciencedaily.com) End-of-dry-season CO2 pulses recur each year in the atmosphere above the Australian continent, a discovery made by an international research team led by an environmental physicist. To investigate the carbon fluxes over Australia, the researchers studied atmospheric CO2 measurements. Their analyses show that CO2 emissions spike when heavy rain falls on dried-out soil, thus activating microorganisms in that soil.
Published Scientists observe flattest explosion ever seen in space
(via sciencedaily.com) Original source Astronomers have observed an explosion 180 million light years away which challenges our current understanding of explosions in space, that appeared much flatter than ever thought possible.
Published 'Taffy galaxies' collide, leave behind bridge of star-forming material
(via sciencedaily.com) Original source The Gemini North telescope, one half of the International Gemini Observatory, operated by NSF's NOIRLab, captured a dazzling image of UGC 12914 and UGC 12915, which are nicknamed the Taffy Galaxies. Their twisted shape is the result of a head-on collision that occurred about 25 million years prior to their appearance in the image. A bridge of highly turbulent gas devoid of significant star formation spans the gap between the two galaxies.
Published Scientists discover hidden crab diversity among coral reefs
(via sciencedaily.com) The Indo-West Pacific is the largest marine ecosystem on Earth, but scientists who study its diversity have to contend with a problem so well-known it was remarked upon by Charles Darwin: related species in the IWP have similar appearances, making it difficult to assess just how many there are. A new study reveals that nearly identical crab species have one consistently distinguishing feature, which only evolves when their ranges overlap.
Published Astronomers witness the birth of a very distant cluster of galaxies from the early Universe
(via sciencedaily.com) Original source Astronomers have discovered a large reservoir of hot gas in the still-forming galaxy cluster around the Spiderweb galaxy -- the most distant detection of such hot gas yet. Galaxy clusters are some of the largest objects known in the Universe and this result further reveals just how early these structures begin to form.
Published Deep ocean currents around Antarctica headed for collapse, study finds
(via sciencedaily.com) Antarctic circulation could slow by more than 40 per cent over the next three decades, with significant implications for the oceans and the climate.
Published AI could set a new bar for designing hurricane-resistant buildings
(via sciencedaily.com) Being able to withstand hurricane-force winds is the key to a long life for many buildings on the Eastern Seaboard and Gulf Coast of the U.S. Determining the right level of winds to design for is tricky business, but support from artificial intelligence may offer a simple solution.
Published How cosmic winds transform galactic environments
(via sciencedaily.com) Original source Much like how wind plays a key role in life on Earth by sweeping seeds, pollen and more from one place to another, galactic winds -- high-powered streams of charged particles and gases -- can change the chemical make-up of the host galaxies they form in, simply by blowing in a specific direction.
Published Earth prefers to serve life in XXS and XXL sizes
(via sciencedaily.com) Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
Published Most of world's salt marshes likely to be underwater by 2100, study concludes
(via sciencedaily.com) Salt marshes are some of the most biologically productive ecosystems on Earth. They play an outsized role in nitrogen cycling, act as carbon sinks, protect coastal development from storm surge, and provide critical habitats and nurseries for many fish, shellfish, and coastal birds. According to new research, more than 90 percent of the world's salt marshes are likely to be underwater by the end of the century. These findings come from a 50-year study of ecosystem changes in Great Sippewissett Marsh in Falmouth, Mass.
Published A reconstruction of prehistoric temperatures for some of the oldest archaeological sites in North America
(via sciencedaily.com) Scientists often look to the past for clues about how Earth's landscapes might shift under a changing climate, and for insight into the migrations of human communities through time. A new study offers both by providing, for the first time, a reconstruction of prehistoric temperatures for some of the first known North American settlements.
Published Detecting coral biodiversity in seawater samples
(via sciencedaily.com) Researchers have developed a method to measure coral biodiversity through extracting the environmental DNA (or eDNA) from a liter of surface seawater collected from above a reef. The method has been confirmed to work through observations made by scientific divers in the same areas of ocean. This has paved the way for large-scale comprehensive surveys of reef-building coral to take place and removes the reliance of direct observations made through scientific scuba diving or snorkeling.
Published Brightest gamma-ray burst ever observed reveals new mysteries of cosmic explosions
(via sciencedaily.com) Scientists believe the gamma-ray emission, which lasted over 300 seconds, is the birth cry of a black hole, formed as the core of a massive and rapidly spinning star collapses under its own weight.
Published SMART warnings could protect communities at risk from flooding
(via sciencedaily.com) Engaging communities in developing a real-time early warning system could help to reduce the often-devastating impact of flooding on people and property -- particularly in mountainous regions where extreme water events are a 'wicked' problem, a new study reveals.
Published How to prepare for ocean acidification, a framework
(via sciencedaily.com) An international research team develops a rubric for governments and policymaking bodies to evaluate preparedness for ocean acidification.
