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.

Decreasing biodiversity may promote spread of viruses      (via sciencedaily.com)     Original source 

How are environmental changes, loss of biodiversity, and the spread of pathogens connected? The answer is a puzzle. Researchers have now described one piece of that puzzle, showing that the destruction of tropical rainforests harms the diversity of mosquito species. At the same time, more resilient species of mosquitoes become more prevalent -- which also means the viruses they carry are more abundant. If there are many individuals of a given species, those viruses can spread quickly.

Exploring the effect of water on seismic wave attenuation in the upper mantle      (via sciencedaily.com)     Original source 

The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the effect of water on the seismic properties of olivine rocks, finding that water retention in the asthenosphere can induce sharp drops in shear wave velocity. This also explained other seismic changes observed at the lithosphere-asthenosphere boundary. These findings provide invaluable insights into the diverse seismic activities on Earth.

Ecological theory can help explain why segregation persists      (via sciencedaily.com)     Original source 

An ecological theory may help to explain why segregation is so widespread and persistent in US cities, according to a new article. The new way of framing segregation's endurance may provide a useful tool to study and address systemic racism, and could ultimately reveal novel ways of breaking the cycle.

Researchers build and test a framework for achieving climate resilience across diverse fisheries      (via sciencedaily.com)     Original source 

What makes for a successful climate-resilient fishery, one that sustainably produces resources for human benefit despite increasing climate stressors and human impacts? It's a question that faces present and future fisheries, their practitioners and fishing communities as the world turns to the ocean to feed its growing population.

How organic solar cells could become significantly more efficient      (via sciencedaily.com)     Original source 

The sun sends enormous amounts of energy to the earth. Nevertheless, some of it is lost in solar cells. This is an obstacle in the use of organic solar cells, especially for those viable in innovative applications. A key factor in increasing their performance: Improved transport of the solar energy stored within the material. Now a research group has shown that certain organic dyes can help build virtual highways for the energy.

Genetically engineering associations between plants and nitrogen-fixing microbes could lessen dependence on synthetic fertilizer      (via sciencedaily.com)     Original source 

Nitrogen is an essential nutrient for plant growth, but the overuse of synthetic nitrogen fertilizers in agriculture is not sustainable. A team of bacteriologists and plant scientists discuss the possibility of using genetic engineering to facilitate mutualistic relationships between plants and nitrogen-fixing microbes called 'diazotrophs.' These engineered associations would help crops acquire nitrogen from the air by mimicking the mutualisms between legumes and nitrogen-fixing bacteria.

Double trouble: Infamous 'eagle killer' bacterium produces not one, but two toxins      (via sciencedaily.com)     Original source 

The cyanobacterium Aetokthonos hydrillicola produces not just one, but two highly potent toxins. Scientists describe the second toxin, which had remained elusive until now. Even in low concentrations, it can destroy cells and is similar to substances currently used in cancer treatment. Two years ago, the same team established that the first toxin from the cyanobacterium is the cause of a mysterious disease among bald eagles in the USA.

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.
