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.

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.

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.

Satellites for quantum communications      (via sciencedaily.com)     Original source 

Through steady advances in the development of quantum computers and their ever-improving performance, it will be possible in the future to crack our current encryption processes. To address this challenge, researchers are developing encryption methods that will apply physical laws to prevent the interception of messages. To safeguard communications over long distances, the QUICK space mission will deploy satellites.

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.

New study shows how AI can help us better understand global threats to wildlife      (via sciencedaily.com)     Original source 

Researchers used AI to scour information from websites and social media to map bat hunting and trade. Research found evidence of bat exploitation in 22 countries that had not previously been identified by traditional academic research. Following concerns about the reliability of the IUCN Red List, new research demonstrates how AI's ability to filter vast amounts of online data can support wildlife conservation.

Grounding zone discovery explains accelerated melting under Greenland's glaciers      (via sciencedaily.com)     Original source 

Researchers have conducted the first large-scale observation and modeling study of northwest Greenland's Petermann Glacier. Their findings reveal the intrusion of warm ocean water beneath the ice as the culprit in the accelerated melting it has experienced since the turn of the century, and their computer predictions indicate that potential sea level rise will be much worse than previously estimated.

AI analysis of historical satellite images show USSR collapse in 1990s increased methane emissions, despite lower oil and gas production      (via sciencedaily.com)     Original source 

An AI-powered analysis of 25 years of satellite images yields the surprising finding that methane emissions in Turkmenistan, a former Soviet republic and major oil-producing region, actually increased in the years following the dissolution of the Soviet Union.

Exploring arctic plants and lichens: An important conservation baseline for Nunavut's newest and largest territorial park      (via sciencedaily.com)     Original source 

A comprehensive study of the floristic diversity of Agguttinni Territorial Park, Nunavut's newest and largest Territorial Park, has documented 141 vascular plant, 69 bryophyte, and 93 lichen species from this unique protected area on northern Baffin Island. Through a combination of extensive fieldwork in 2021 and examination of hundreds of existing herbarium specimens, the authors have documented species newly reported for Baffin Island and have crafted a biodiversity baseline important for park management and conservation.

History repeats as Coral Bay faces mass loss of coral and fish life      (via sciencedaily.com)     Original source 

A perfect storm of environmental factors has seen a monumental loss of fish and coral life at a popular area of Ningaloo Reef in Western Australia's Gascoyne region -- however research into the event shows there is hope it will recover. In March 2022, during the annual coral spawning event, calm weather and limited tidal movement combined to trap the coral's eggs within Bills Bay, at the town of Coral Bay. This led to an excess of nutrients in the water which consumed more oxygen than usual -- causing massive numbers of fish and corals to die from asphyxiation.

Rice paddy snake diversification was driven by geological and environmental factors in Thailand, molecular data suggests      (via sciencedaily.com)     Original source 

A new study of rice paddy snakes in Southeast Asia gives key details to their diversification and natural history, adding molecular evidence that the rise of the Khorat Plateau and subsequent environmental shifts in Thailand may have altered the course of the snakes' evolution some 2.5 million years ago.

Mars attracts: How Earth's interactions with the red planet drive deep-sea circulation      (via sciencedaily.com)     Original source 

Scientists have used the geological record of the deep sea to discover a connection between the orbits of Earth and Mars, past global warming patterns and the speeding up of deep ocean circulation. The patterns they discover suggest that warming seas could produce deep whirpools in ocean currents.

Pronghorn population declining due to human development      (via sciencedaily.com)     Original source 

A new article looked at 40 years of data collected on 40 pronghorn herds residing in the Wyoming Basin Shrub Steppe. Overall, 80% of the herds saw a decrease in productivity, and nearly 43% saw a significant decrease. After looking at a number of variables that could potentially contribute to the decline, the researchers identified the two most strongly associated: development of oil and gas resources and woody encroachment.

Interstellar signal linked to aliens was actually just a truck      (via sciencedaily.com)     Original source 

Sound waves thought to be from a 2014 meteor fireball north of Papua New Guinea were almost certainly vibrations from a truck rumbling along a nearby road, new research shows. The findings raise doubts that materials pulled last year from the ocean are alien materials from that meteor, as was widely reported.
