Published A wetter world recorded in Australian coral colony
(via sciencedaily.com) Original source When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world. Some scientists are also looking at something a little more tangible: coral.
Published Fish species that move rapidly toward the poles due to global warming decline in abundance, study finds
(via sciencedaily.com) Original source A new study has found a decline in the abundance of marine fish species that move rapidly toward the poles to escape rising sea temperatures. The researchers explain that many animal species are currently moving toward cooler regions as a result of global warming, but the velocity of such range shifts varies greatly for different species. Examining thousands of populations from almost 150 fish species, the researchers show that contrary to the prevailing view, rapid range shifts coincide with widescale population declines.
Published Transforming wood waste for sustainable manufacturing
(via sciencedaily.com) Original source Research is exploring how to add value to lignin by breaking it down into small molecules that are structurally similar to oxygenated hydrocarbons. These renewable chemicals are key components in many industrial processes and products, but they are traditionally sourced from non-renewable petroleum.
Published Self-heating concrete is one step closer to putting snow shovels and salt out of business
(via sciencedaily.com) Original source Researchers recently reported on the science behind its special concrete, that can warm itself up when it snows, or as temperatures approach freezing.
Published Reimagining the future of solar energy
(via sciencedaily.com) Original source New research suggests that there might be other ways to generate solar energy than just trying to make individual solar cells super-efficient.
Published Oregon State researchers take deep dive into how much water is stored in snow
(via sciencedaily.com) Original source There's a new metric that provides a more holistic look at how much water is stored in snowpack, and for how long.
Published Even inactive smokers are densely colonized by microbial communities
(via sciencedaily.com) Original source Everything is everywhere -- under certain conditions microbial communities can grow and thrive, even in places that are seemingly uninhabitable. This is the case at inactive hydrothermal vents on the sea floor. An international team is presently working to accurately quantify how much inorganic carbon can be bound in these environments.
Published Meteorology: Weak polar vortex makes weather more predictable
(via sciencedaily.com) Original source Events in the stratosphere are making long-range weather in Northern Europe easier to forecast, researchers have discovered.
Published The atlas of unburnable oil in the world
(via sciencedaily.com) Original source In order to limit the increase in global average temperature to 1.5 C, it is essential to drastically reduce carbon dioxide emissions in the atmosphere. This would mean not exploiting most of the existing coal, conventional gas and oil energy resources in regions around the world, according to new research. The study presents the atlas of unburnable oil in the world, a world map designed with environmental and social criteria that warns which oil resources should not be exploited to meet the commitments of the Paris Agreement signed in 2015 to mitigate the effects of climate change.
Published Protein fragments ID two new 'extremophile' microbes--and may help find alien life
(via sciencedaily.com) Original source Perfectly adapted microorganisms live in extreme environments from deep-sea trenches to mountaintops. Learning more about how these extremophiles survive in hostile conditions could inform scientists about life on Earth and potential life on other planets.
Published Shark-bitten orcas in the Northeastern Pacific could be a new population of killer whale
(via sciencedaily.com) Original source Researchers believe a group of killer whales observed hunting marine mammals including sperm whales, as well as a sea turtle, in the open ocean off California and Oregon could be a new population. Based on available evidence, the researchers posit that the 49 orcas could belong to a subpopulation of transient killer whales or a unique oceanic population found in waters off the coast of California and Oregon.
Published Groundbreaking study reveals extensive leatherback turtle activity along U.S. coastline
(via sciencedaily.com) Original source A new study provides groundbreaking findings that offer insights on the migration and foraging patterns of leatherback sea turtles along the Northwest Atlantic shelf.
Published Diverse habitats help salmon weather unpredictable climate changes
(via sciencedaily.com) Original source Restored salmon habitat should resemble financial portfolios, offering fish diverse options for feeding and survival so that they can weather various conditions as the climate changes, a new study shows.
Published Information overload is a personal and societal danger
(via sciencedaily.com) Original source We are all aware of the dangers of pollution to our air, water, and earth. In a recently published letter, scientists are advocating for the recognition and mitigation of another type of environmental pollution that poses equivalent personal and societal dangers: information overload.
Published Researchers can reveal illegal timber exports
(via sciencedaily.com) Original source A new method of timber analysis can confidently identify the location in which the tree was harvested. The method has been developed with the aim of combating illegal timber imports from Russia and Belarus.
Published Surprising insights about debris flows on Mars
(via sciencedaily.com) Original source The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by liquid water, can also be formed by the action of evaporating CO2 ice, according to a new study.
Published It's hearty, it's meaty, it's mold
(via sciencedaily.com) Original source Scientists are exploring how tuning the genomes of mushrooms and molds can transform these food sources into gourmet, nutrient-packed meals made with minimal processing and a light environmental footprint.
Published Tropical birds could tolerate warming better than expected, study suggests
(via sciencedaily.com) Original source We expect tropical animals to handle a certain degree of heat, but not wild swings in temperature. That seems to be true for tropical ectotherms, or 'cold-blooded' animals such as amphibians, reptiles, and insects. However, in a new study of 'warm-blooded' endotherms, a research team found tropical birds can handle thermal variation just fine.
Published Asian aerosols' impact on Atlantic Meridional Overturning Circulation
(via sciencedaily.com) Original source A new study identifies the role aerosols over Asia is having on the AMOC, a complex system of currents in the Atlantic Ocean.
Published With discovery of roundworms, Great Salt Lake's imperiled ecosystem gets more interesting
(via sciencedaily.com) Original source Biologists announce the discovery of numerous species of roundworm in the highly saline waters of Great Salt Lake, the vast terminal lake in northwestern Utah that supports millions of migratory birds. Previously, brine shrimp and brine flies were the only known multicellular animals living in the water column. The scientists found nematodes, belonging to a family known for inhabiting extreme environments, in the lake's microbialites, reef-like structures covering about a fifth of the lakebed.
