Aerosol pollution, greenhouse gases must be reduced simultaneously to keep forest fires in check      (via sciencedaily.com)     Original source 

If we want cleaner air, fewer forest fires, and less severe climate change, a new study shows we must reduce aerosol pollution and greenhouse gases like carbon dioxide at the same time.

Fatal attraction: When endangered species try to mate with domestic relatives, both wildlife and people lose      (via sciencedaily.com)     Original source 

Sticks and stones aren't enough to thwart biological attraction, but sometimes those are the only tools available to pastoralists trying to prevent wildlife from eloping with their livestock. A new study brings awareness to both the human impacts of these encounters -- ranging from economic loss to death -- and conservation concerns for the wild animals that are often endangered.

Some species may tolerate climate change better than expected      (via sciencedaily.com)     Original source 

A new model reassesses the proportion of terrestrial and marine species threatened with extinction by climate change. While the forecasts of traditional models estimate that the diversity of terrestrial species in tropical areas could decrease by 54% between now and 2041-2060, this model is more moderate, predicting a decrease of 39%. Nevertheless, this proportion remains alarming and confirms the importance of taking urgent measures to mitigate climate change and its impact on biodiversity.

Biobased building materials less sustainable than concrete in South Africa, experts find      (via sciencedaily.com)     Original source 

Scientists have discovered that mycelium composites, biobased materials made from fungi and agricultural residues, can have a greater environmental impact than conventional fossil-fuel-based materials due to the high amount of electricity involved in their production.

Wild megalopolis: Study shows unexpected pockets of biodiversity pepper Los Angeles      (via sciencedaily.com)     Original source 

Researchers, in partnership with the city of Los Angeles, have developed the urban association index to help identify how well or poorly individual wildlife species are doing in the city. The researchers found unexpected pockets of biodiversity deep in the city, but they say it will still be a challenge to elevate Los Angeles' overall level of biodiversity.

Smarter foragers do not forage smarter      (via sciencedaily.com)     Original source 

Why do primates have big brains? In the Panamanian rainforest, scientists pitted large-brained primates against smaller-brained mammals to find out who was the smartest forager.

Bringing back an ancient bird      (via sciencedaily.com)     Original source 

Using ancient DNA extracted from the toe bone of a museum specimen, biologists have sequenced the genome of an extinct, flightless bird called the little bush moa, shedding light into an unknown corner of avian genetic history. The work is the first complete genetic map of the turkey-sized bird whose distant living cousins include the ostrich, emu, and kiwi.

Improved refrigeration could save nearly half of the 1.3 billion tons of food wasted each year globally      (via sciencedaily.com)     Original source 

A new study concludes that nearly half of the food waste, about 620 million metric tons, could be eliminated by fully refrigerated food supply chains worldwide. At the same time, fully refrigerated supply chains, or 'cold chains,' could cut food waste-related emissions of climate-warming greenhouse gases by 41% globally, according to a new study.

Prenatal exposure to air pollution associated with increased mental health risks      (via sciencedaily.com)     Original source 

A baby's exposure to air pollution while in the womb is associated with the development of certain mental health problems once the infant reaches adolescence, new research has found. The study examined the long-term mental health impact of early-life exposure to air and noise pollution.

Understanding the mechanisms for local amplification of 2024 tsunamis in Iida Bay      (via sciencedaily.com)     Original source 

Researchers uncover the unique mechanisms that resulted in severe tsunamis in Iida Bay caused by the 2024 Noto Peninsula Earthquake. The recent tsunamis in Iida Bay were locally amplified due to various factors, including ocean floor topology, the shape of the coastline, the location of coastal facilities, and seismic mechanisms associated with earthquakes, report scientists.

Study suggests 'biodegradable' teabags don't readily deteriorate in the environment and can adversely affect terrestrial species      (via sciencedaily.com)     Original source 

New research looked at commonly available teabags made using three different compositions of polylactic acid (PLA), which is derived from sources such as corn starch or sugar cane. The teabags were buried in soil for seven months, and a range of techniques were then used to assess whether -- and to what extent -- they had deteriorated. The results showed that teabags made solely from PLA remained completely intact. However, the two types of teabags made from a combination of cellulose and PLA broke down into smaller pieces, losing between 60% and 80% of their overall mass and with the PLA component remaining.
