Sonic youth: Healthy reef sounds increase coral settlement      (via sciencedaily.com)     Original source 

Healthy coral reefs have rich soundscapes, full of the croaks, purrs, and grunts of various fishes and the crackling of snapping shrimp. Larval coral uses these sounds as cues to identify the best places to settle and grow. The authors found that sound could potentially be a vital tool in the effort to restore coral reefs. Broadcasting the sounds of a healthy reef to a reef that is degraded encourages coral larvae to settle there. This indicates that it's possible that 'acoustic enrichment' can be a key intervention to support imperiled reefs.

Molecular simulations of ammonia mixtures support search for renewable fuels      (via sciencedaily.com)     Original source 

Ammonia is an important molecule with many applications. The end product of the famed Haber-Bosch process, it is commonly synthesized to capture nitrogen for fertilizers, and is used for refrigeration, in cleaning products, and in the production of pharmaceuticals. Recently, this modest molecule has also attracted interest as a potential resource for addressing one of today's most pressing challenges -- the need for reliable and abundant renewable fuels.

New high-performance solar cell material      (via sciencedaily.com)     Original source 

A new study reports the discovery of an entirely new stable, earth-abundant, high-performance material for solar absorbers -- the central part of a solar cell that turns light into electricity. While identifying new solar materials is typically very time-consuming, the researchers used a unique high-throughput computational screening method to quickly evaluate around 40,000 candidate materials.

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.

Giant sequoias are a rapidly growing feature of the UK landscape      (via sciencedaily.com)     Original source 

Imported giant sequoia trees are well adapted to the UK, growing at rates close to their native ranges and capturing large amounts of carbon during their long lives, finds a new study.

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.

Vehicle brakes produce charged particles that may harm public health      (via sciencedaily.com)     Original source 

Scientists know relatively little about particles released into the air when a vehicle driver brakes, though evidence suggests those particles may be more harmful to health than particles exiting the tailpipe.

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.

A coral superhighway in the Indian Ocean      (via sciencedaily.com)     Original source 

Despite being scattered across more than a million square kilometers, new research has revealed that remote coral reefs across the Seychelles are closely related. Using genetic analyses and oceanographic modelling, researchers demonstrated for the first time that a network of ocean currents scatter significant numbers of larvae between these distant islands, acting as a 'coral superhighway.'

Scientists propose new theory that explains sand ripples on Mars and on Earth      (via sciencedaily.com)     Original source 

Sand ripples are symmetrical. Yet wind -- which causes them -- is very much not. Furthermore, sand ripples can be found on Mars and on Earth. They would be even more fascinating if the same effect found on Mars could be found here on Earth as well. What if one unified theory could explain their formation on both planets?

Rock weathering and climate: Low-relief mountain ranges are largest carbon sinks      (via sciencedaily.com)     Original source 

For many hundreds of millions of years, the average temperature at the surface of the Earth has varied by not much more than 20 degrees Celsius, facilitating life on our planet. To maintain such stable temperatures, Earth appears to have a 'thermostat' that regulates the concentration of atmospheric carbon dioxide over geological timescales, influencing global temperatures. The erosion and weathering of rocks are important parts of this 'thermostat.'
