Scientists outline a bold solution to climate change, biodiversity loss, social injustice      (via sciencedaily.com)     Original source 

An international team of scientists has used a novel 500-year dataset to frame a 'restorative' pathway through which humanity can avoid the worst ecological and social outcomes of climate change.

Final supernova results from Dark Energy Survey offer unique insights into the expansion of the universe      (via sciencedaily.com)     Original source 

In the culmination of a decade's worth of effort, scientists analyzed an unprecedented sample of more than 1,500 supernovae classified using machine learning. They placed the strongest constraints on the expansion of the universe ever obtained with the DES supernova survey. While consistent with the current standard cosmological model, the results do not rule out a more complex theory that the density of dark energy in the universe could have varied over time.

Global study of extreme drought impacts on grasslands and shrublands      (via sciencedaily.com)     Original source 

A global study shows that the effects of extreme drought -- which is expected to increase in frequency with climate change -- has been greatly underestimated for grasslands and shrublands. The findings quantify the impact of extreme short-term drought on grassland and shrubland ecosystems across six continents with a level of detail that was not previously possible. It is the first time an experiment this extensive has been undertaken to generate a baseline understanding of the potential losses of plant productivity in these vital ecosystems.

Protecting coral 'nurseries' as important as safeguarding established coral reefs      (via sciencedaily.com)     Original source 

New research in the southwestern part of Hawai'i Island shows that identifying and protecting marine ecosystems both down-current and up-current of coral reefs, specifically areas where coral larvae are more likely to survive and thrive, is crucial to future coral conservation and restoration efforts -- especially as reefs face increasing pressure from the devastating effects of climate change.

Preventing the destruction of Eucalyptus forest plantations: Naturally occurring pathogenic fungi to control the Eucalyptus snout beetle      (via sciencedaily.com)     Original source 

Scientists have found naturally occurring pathogenic fungi infecting the Eucalyptus snout beetle in Eucalyptus forest plantations, and characterized them to develop a bio-pesticide for controlling the beetle.

Three iron rings in a planet-forming disk      (via sciencedaily.com)     Original source 

Astronomers have detected a three-ringed structure in the nursery of planets in the inner planet-forming disk of a young star. This configuration suggests two Jupiter-mass planets are forming in the gaps between the rings. The detailed analysis is consistent with abundant solid iron grains complementing the dust composition. As a result, the disk likely harbors metals and minerals akin to those in the Solar System's terrestrial planets. It offers a glimpse into conditions resembling the early Solar System over four billion years ago during the formation of rocky planets such as Mercury, Venus, and Earth.

Accounting for plastic persistence can minimize environmental impacts      (via sciencedaily.com)     Original source 

Researchers have developed a sustainability metric for the ecological design of plastic products that have low persistence in the environment. Adhering to this metric could provide substantial environmental and societal benefits, according to a new study.

Space oddity: Uncovering the origin of the universe's rare radio circles      (via sciencedaily.com)     Original source 

Astronomers believe they may have found the origin of the universe's giant odd radio circles: they are shells formed by outflowing galactic winds, possibly from massive exploding stars known as supernovae.

Use of habitat for agricultural purposes puts primate infants at risk      (via sciencedaily.com)     Original source 

Frequent visits to oil palm plantations are leading to a sharp increase in mortality rates among infant southern pig-tailed macaques (Macaca nemestrina) in the wild, according to a new study. In addition to increased risk from predators and human encounters, exposure to harmful agricultural chemicals in this environment may negatively affect infant development.

Monitoring the well-being of reservoir water through an uncrewed surface vehicle      (via sciencedaily.com)     Original source 

In a recent tragic incident, approximately 100 elephants in Africa perished due to inadequate access to water. The United Nations Environment Programme (UNEP) issues a warning that around 2.5 billion people worldwide could face water scarcity by 2025. In the face of water shortages affecting not only human society but also the entire ecological community due to the climate crisis, it becomes crucial to adopt comprehensive measures for managing water quality and quantity to avert such pressing challenges.

New images reveal what Neptune and Uranus really look like      (via sciencedaily.com)     Original source 

Neptune is fondly known for being a rich blue and Uranus green -- but a new study has revealed that the two ice giants are actually far closer in color than typically thought. The correct shades of the planets have now been confirmed.

Conflict in full swing: Forest bats avoid large areas around fast-moving wind turbines      (via sciencedaily.com)     Original source 

Not only do many bats die at wind turbines, the turbines also displace some species from their habitats over large areas. When the turbines are in operation at relatively high wind speeds, the activity of bat species that hunt in structurally dense habitats such as forests drops by almost 80 per cent within a radius of 80 to 450 meters around the turbine.

Microbial awakening restructures high-latitude food webs as permafrost thaws      (via sciencedaily.com)     Original source 

Wildlife biologists used a novel technique to trace the movement of carbon through Arctic and boreal forest food webs and found that climate warming resulted in a shift from plant-based food webs to fungal-based food webs for several high-latitude species, with potential indirect effects on nutrient cycling and ecosystem function.

A recent study assessed the perspectives of 76 diverse South Florida climate adaptation professionals. A new study explores the expectations and concerns of practitioners from the private sector, community-based organizations, and government agencies about the region's ability to adapt in the face of increasing sea level rise and diverse consequences for where people live and move, also known as climate mobility.

Hubble sights a galaxy with 'forbidden' light      (via sciencedaily.com)     Original source 

A whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core known as an active galactic nucleus (AGN) and is categorized as a Type-2 Seyfert galaxy. Seyfert galaxies, along with quasars, host one of the most common subclasses of AGN. While the precise categorization of AGNs is nuanced, Seyfert galaxies tend to be relatively nearby and their central AGN does not outshine its host, while quasars are very distant AGNs with incredible luminosities that outshine their host galaxies.
