New insect genus discovered in one of the most biodiverse rain forest regions in the world      (via sciencedaily.com)     Original source 

The Allpahuayo-Mishana National Reserve in Peru has often been described as the most biodiverse rainforest in the world. For example, in recent decades, scientist have discovered several new bird species from the region. Researchers from the University of Turku in Finland have studied the insect biodiversity in Allpahuayo-Mishana for over 20 years. In their latest study, the scientist described a new wasp genus, Capitojoppa, to science.

Scientists reveal what fuels wildfires in Sierra Nevada Mountains      (via sciencedaily.com)     Original source 

Wildfires in California, exacerbated by human-driven climate change, are getting more severe. To better manage them, there's a growing need to know exactly what fuels the blazes after they ignite. Scientists now report that one of the chief fuels of wildfires in California's Sierra Nevada mountains is the decades-old remains of large trees.

How climate warming could disrupt a deep-rooted relationship      (via sciencedaily.com) 

Trees depend on fungi for their well-being. As climate change and global warming cause higher temperatures and amplified drought, little is known about how these important fungi will respond. To investigate this issue, a research team conducted a climate change experiment where they exposed boreal and temperate tree species to warming and drought treatments to better understand how fungi and their tree hosts respond to environmental changes. Their findings revealed that the combined effects of warming and water stress will likely result in major disturbances of ectomycorrhizal networks and may harm forest resilience and function.

Sustainable energy for aviation: What are our options?      (via sciencedaily.com) 

Scientists and industry leaders worldwide are looking for answers on how to make aviation sustainable by 2050 and choosing a viable sustainable fuel is a major sticking point. Aerospace engineers took a full inventory of the options to make a data-driven assessment about how they stack up in comparison. He reviewed over 300 research projects from across different sectors, not just aerospace, to synthesize the ideas and draw conclusions to help direct the dialogue about sustainable aviation toward a permanent solution.

Plant and forest researchers do not 'anthropomorphize' plants      (via sciencedaily.com)     Original source 

Plants are often attributed with abilities similar to those known in the animal or human world. Trees are said to have feelings and can therefore care for their offspring, like mothers. Researchers analyzed the claims in two popular publications on forests and reached the conclusion that conjecture is equated with fact. They warn against 'anthropomorphizing' plants.

Researchers offer insights into solid-electrolyte interphases in next-gen aqueous potassium-ion batteries      (via sciencedaily.com) 

Aqueous potassium-ion batteries are a promising alternative to lithium-ion batteries owing to their safety and low cost. However, not much is known about the properties of the solid-electrolyte interphases (SEI) that form between the electrode and the aqueous electrolyte. To address this knowledge gap, researchers from Japan have now conducted a study using advanced scanning electrochemical microscopy and operando electrochemical mass spectrometry. Their findings provide a deeper understanding of SEI in next-generation batteries.

Almost half of koala habitats will be under high bushfire threat by 2070      (via sciencedaily.com) 

The research team generated a series of fire susceptibility maps. These show the proportion of Australia experiencing 'high' or 'very high' fire susceptibility increasing from 14.9% now to 15.66% by 2070 -- while fire susceptibility of areas suitable for the plants that koalas depend on is tipped to jump from 39.56% to 44.61% by 2070.

Study shows replanting logged forests with diverse mixtures of seedlings accelerates restoration      (via sciencedaily.com) 

• Twenty-year experiment finds that active replanting beats natural recovery for restoring logged tropical forests. • The higher the diversity of replanted tree species, the more quickly canopy area and biomass recovered. • Results emphasize the importance of preserving biodiversity in pristine forests and restoring it in recovering logged forest.

New research highlights opportunities to protect carbon and communities from forest fires      (via sciencedaily.com)     Original source 

As the climate and wildfire crises have intensified, so too have concerns regarding the loss of carbon captured and stored in forests from decades to centuries of tree growth. A new study describes where to optimize ongoing wildfire mitigation efforts and reduce carbon loss due to wildfire, benefitting communities and climate at the same time. The study evaluated where living trees and the carbon they store are at risk of burning in the future. They then compared these areas to communities that are vulnerable to wildfire as identified in the Forest Service's Wildfire Crisis Strategy. Areas of overlap highlight 'opportunity hot spots' where action can reduce the risk from wildfire to both carbon and communities.

Human shoulders and elbows first evolved as brakes for climbing apes      (via sciencedaily.com)     Original source 

Researchers report that the flexible shoulders and elbows that allow us to throw a football or reach a high shelf may have evolved as a natural braking system that let our primate ancestors get out of trees without dying. The researchers used sports-analysis software to compare the climbing movements of chimpanzees and small monkeys called mangabeys. While the animals climb up trees similarly, the researchers found that the shallow, rounded shoulder joints and shortened elbow bones that chimps have -- similar to humans -- allow them to fully extend their arms above their heads when climbing down, holding onto branches like a person going down a ladder to support their greater weight. When early humans left forests for the grassy savanna, these versatile appendages would have been essential for gathering food and using tools for hunting and defense. The findings are among the first to identify the significance of 'downclimbing' in the evolution of apes and early humans.

Efficient and mild: Recycling of used lithium-ion batteries      (via sciencedaily.com) 

Lithium-ion batteries (LIBs) provide our portable devices like tablets and mobiles -- and increasingly also vehicles -- with power. As the share of volatile renewable energy needing electricity storage increases, more and more LIBs are needed, lithium prices rise, resources dwindle, and the amount of depleted batteries that contain toxic substances increases. Researchers introduce a novel approach for the recovery of lithium from used LIBs.
