Galactic bloodlines: Many nearby star clusters originate from only three 'families'      (via sciencedaily.com)     Original source 

Astronomers have deciphered the formation history of young star clusters, some of which we can see with the naked eye at night. The team reports that most nearby young star clusters belong to only three families, which originate from very massive star-forming regions. This research also provides new insights into the effects of supernovae (violent explosions at the end of the life of very massive stars) on the formation of giant gas structures in galaxies like our Milky Way.

Basic income can double global GDP while reducing carbon emissions      (via sciencedaily.com)     Original source 

Giving a regular cash payment to the entire world population has the potential to increase global gross domestic product (GDP) by 130%, according to a new analysis. Researchers suggest that charging carbon emitters with an emission tax could help fund such basic income program while reducing environmental degradation.

Mushroom stump waste could be inexpensive, healthy chicken feed supplement      (via sciencedaily.com)     Original source 

Feed costs for producing broiler chickens accounts for 60% to 70% of total production costs, and stump waste from the production of button mushrooms comprises nearly 30% of total mushroom weight. Marrying the two has the potential to reduce both cost and waste, especially in Pennsylvania, which is a national leader in the production of broiler chickens and button mushrooms.

Climate crisis puts Australia's ski industry on slippery slope, but not all hope is lost      (via sciencedaily.com)     Original source 

Australia's ski industry is at risk of major disruptions and shorter seasons if the current level of climate pollution continues, according to new modelling. The report found the average ski season across all resorts in Australia will be 44 days shorter by 2050 under a mid-greenhouse gas emissions scenario and 55 days shorter under a high-emissions scenario.

Tropical forests adjust strategies to thrive even when soils are nutrient poor      (via sciencedaily.com)     Original source 

Tropical forests store a third of the world's carbon in their wood and soils. However, their future as a carbon sink has been uncertain. Scientists have long wondered whether nutrient-poor tropical soils would limit the ability of mature and recovering forests to thrive. A study offers a hopeful response, suggesting that forests have flexible strategies that help them overcome the challenge of scarce nutrients.

Uptake of tire wear additives by vegetables grown for human consumption      (via sciencedaily.com)     Original source 

Car tires contain hundreds of chemical additives that can leach out of them. This is how they end up in crops and subsequently in the food chain. Researchers have now detected these chemical residues in leafy vegetables for the first time. Although the concentrations were low, the evidence was clear, a finding that is also known for drug residues in plant-based foods.
