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 New research suggests that our universe has no dark matter
(via sciencedaily.com) Original source A new study challenges the current model of the universe by showing that, in fact, it has no room for dark matter.
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 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 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 Advanced army robots more likely to be blamed for deaths
(via sciencedaily.com) Original source Advanced killer robots are more likely to blamed for civilian deaths than military machines, new research has revealed. The study shows that high-tech bots will be held more responsible for fatalities in identical incidents.
Published An electricity generator inspired by the drinking bird toy powers electronics with evaporated water
(via sciencedaily.com) Original source Inspired by the classic drinking bird toy, scientists have developed an engine that efficiently converts energy from water evaporation into electricity to power small electronics. The device produces energy outputs exceeding 100 volts -- much higher than other techniques that generate electricity from water -- and can operate for several days using only 100 milliliters of water as fuel, according to a new study.
Published Chimp moms play with their offspring through good times and bad
(via sciencedaily.com) Original source A recent study observing wild chimpanzees over a period of more than 10 years revealed that when food gets scarcer, the adults put play aside and focus on survival, while mother chimps continue to be their children's primary playmate -- suggesting their indispensable role to foster their young's physical and social development.
Published What kinds of seismic signals did Swifties send at LA concert?
(via sciencedaily.com) Original source Seattle may have experienced its own Swift Quake last July, but at an August 2023 concert Taylor Swift's fans in Los Angeles gave scientists a lot of shaking to ponder. After some debate, a research team concluded that it was likely the dancing and jumping motions of the audience at SoFi Stadium -- not the musical beats or reverberations of the sound system -- that generated the concert's distinct harmonic tremors.
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 Robot ANYmal can do parkour and walk across rubble
(via sciencedaily.com) Original source The quadrupedal robot ANYmal went back to school and has learned a lot. Researchers used machine learning to teach it new skills: the robot can now climb over obstacles and successfully negotiate pitfalls.
Published The future is likely less skiable, thanks to climate change
(via sciencedaily.com) Original source Annual snow cover days in all major skiing regions are projected to decrease dramatically as a result of climate change, with 1 in 8 ski areas losing all natural snow cover this century under high emission scenarios, according to a new study.
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.
Published Marine heat waves disrupt the ocean food web in the northeast Pacific Ocean
(via sciencedaily.com) Original source Marine heat waves in the northeast Pacific Ocean create ongoing and complex disruptions of the ocean food web that may benefit some species but threaten the future of many others, a new study has shown.
Published New AI technology enables 3D capture and editing of real-life objects
(via sciencedaily.com) Original source Imagine performing a sweep around an object with your smartphone and getting a realistic, fully editable 3D model that you can view from any angle -- this is fast becoming reality, thanks to advances in AI. Researchers have unveiled new AI technology for doing exactly this. Soon, rather than merely taking 2D photos, everyday consumers will be able to take 3D captures of real-life objects and edit their shapes and appearance as they wish, just as easily as they would with regular 2D photos today.
Published Researchers develop a new control method that optimizes autonomous ship navigation
(via sciencedaily.com) Original source Existing ship control systems using Model Predictive Control for Maritime Autonomous Surface Ships (MASS) do not consider the various forces acting on ships in real sea conditions. Addressing this gap, researchers developed a novel time-optimal control method, that accounts for the real wave loads acting on a ship, enabling effective planning and control of MASS at sea.
Published You don't need glue to hold these materials together -- just electricity
(via sciencedaily.com) Original source Is there a way to stick hard and soft materials together without any tape, glue or epoxy? A new study shows that applying a small voltage to certain objects forms chemical bonds that securely link the objects together. Reversing the direction of electron flow easily separates the two materials. This electro-adhesion effect could help create biohybrid robots, improve biomedical implants and enable new battery technologies.
Published High resolution imagery advances the ability to monitor decadal changes in emperor penguin populations
(via sciencedaily.com) Original source Emperor penguin populations have been exceedingly difficult to monitor because of their remote locations, and because individuals form breeding colonies on seasonal sea ice fastened to land (known as fast ice) during the dark and cold Antarctic winter. New research that incorporates very high-resolution satellite imagery with field-based validation surveys and long-term data has provided the first multi-year time series that documents emperor penguin global population trends.
