Lightning strike creates phosphorus material      (via sciencedaily.com)     Original source 

A lightning strike in New Port Richey, Florida, led to a chemical reaction creating a new material that is transitional between space minerals and minerals found on Earth. High-energy events, such as lightning, can cause unique chemical reactions. In this instance, the result is a new material -- one that is transitional between space minerals and minerals found on Earth.

Warm liquid spewing from Oregon seafloor comes from Cascadia fault, could offer clues to earthquake hazards      (via sciencedaily.com)     Original source 

Oceanographers discovered warm, chemically distinct liquid shooting up from the seafloor about 50 miles off Newport. They named the unique underwater spring 'Pythia's Oasis.' Observations suggest the spring is sourced from water 2.5 miles beneath the seafloor at the plate boundary, regulating stress on the offshore subduction zone fault.

Family tree of 'boring' butterflies reveals they're anything but      (via sciencedaily.com)     Original source 

Important species often get overlooked if they lack flashy colors or charismatic behavior. This is true of euptychiine butterflies, one of the most common insects in the Amazon Rainforest that have been largely ignored by scientists and naturalists throughout the 20th century. A new study pieces together the natural history of the group, in which males can look so unlike females, they've been repeatedly mistaken for separate species, diversity has been drastically underestimated, and more than 100 unnamed species are waiting on scientific description.

Scientists advocate for integration of biogeography and behavioral ecology to rapidly respond to biodiversity loss      (via sciencedaily.com)     Original source 

An interdisciplinary team of researchers is advocating for convergent research that integrates the fields of biogeography and behavioral ecology to more rapidly respond to challenges associated with climate change and biodiversity loss.

Scientists show how we can anticipate rather than react to extinction in mammals      (via sciencedaily.com)     Original source 

Most conservation efforts are reactive. Typically, a species must reach threatened status before action is taken to prevent extinction, such as establishing protected areas. A new study shows that we can use existing conservation data to predict which currently unthreatened species could become threatened and take proactive action to prevent their decline before it is too late.

In Florida study, nonnative leaf-litter ants are replacing native ants      (via sciencedaily.com)     Original source 

A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants -- even in protected natural areas of the state, researchers report.

Environmental impact reports hugely underestimate consequences for wildlife      (via sciencedaily.com)     Original source 

Research shows that environmental impact reports hugely underestimate the consequences of new developments for wildlife. This is because they don't take into account how birds and other animals move around between different sites. The research shows how a planned airport development in Portugal could affect more than 10 times the number of Black-tailed Godwits estimated in a previous Environmental Impact Assessment. The team have been studying these Godwits across Europe for over 30 years but they say that any species that moves around is likely to be under-represented by such reports.

Sierra squirrels find their niche amid a changing climate      (via sciencedaily.com)     Original source 

A new study of squirrels in California's Sierra Nevada mountains finds that climate is just one factor impacting where species make their homes in a changing world.

Moving towards 3 degrees of warming -- the phasing out of coal is too slow      (via sciencedaily.com)     Original source 

The use of coal power is not decreasing fast enough. The Paris Agreement's target of a maximum of 2 degrees of warming appear to be missed, and the world is moving towards a temperature increase of 2.5 -- 3 degrees. At the same time it is feasible to avoid higher warming.

Underground water could be the solution to green heating and cooling      (via sciencedaily.com)     Original source 

About 12% of the total global energy demand comes from heating and cooling homes and businesses. A new study suggests that using underground water to maintain comfortable temperatures could reduce consumption of natural gas and electricity in this sector by 40% in the United States. The approach, called aquifer thermal energy storage (ATES), could also help prevent blackouts caused by high power demand during extreme weather events.

Lifting the veil on disease avoidance strategies in multiple animal species      (via sciencedaily.com)     Original source 

A framework has been developed to test disgust and its associated disease avoidance behaviors across various animal species, social systems, and habitats. Over 30 species have been predicted to exhibit disease avoidance strategies in the wild. With these predictions, the team accounts for models of specific ecological niches, sensory environments and social systems for a number of species including the native common octopus and the invasive red-eared slider, which are both relevant to Japan.

Researchers correlate Arctic warming to extreme winter weather in midlatitude and its future      (via sciencedaily.com)     Original source 

A warmer Arctic has been linked to extreme winter weather in the midlatitude regions. But, it is not clear how global warming affects this link. In a new study, researchers show, using weather data and climate models, that while the 'Warm Arctic-Cold Continent' pattern will continue as the climate continues to warm, Arctic warming will become a less reliable predictor of extreme winter weather in the future.

The unexpected contribution of medieval monks to volcanology      (via sciencedaily.com)     Original source 

By observing the night sky, medieval monks unwittingly recorded some of history's largest volcanic eruptions. An international team of researchers drew on readings of 12th and 13th century European and Middle Eastern chronicles, along with ice core and tree ring data, to accurately date some of the biggest volcanic eruptions the world has ever seen. Their results uncover new information about one of the most volcanically active periods in Earth's history, which some think helped to trigger the Little Ice Age, a long interval of cooling that saw the advance of European glaciers.

Was plate tectonics occurring when life first formed on Earth?      (via sciencedaily.com)     Original source 

Researchers used small zircon crystals to unlock information about magmas and plate tectonic activity in early Earth. The research provides chemical evidence that plate tectonics was most likely occurring more than 4.2 billion years ago when life is thought to have first formed on our planet. This finding could prove beneficial in the search for life on other planets.

A detailed map of the microverse: Microbial niches      (via sciencedaily.com)     Original source 

What defines the habitat -- the ecological niche -- of a microorganism? It is a combination of environmental factors such as temperature, moisture, and nutrient content. But the exact contribution of each of these factors is difficult to predict. A research team has redefined microbial niches by determining which microorganisms live together.

Insect decline also occurs in forests      (via sciencedaily.com)     Original source 

The number of insects has been declining for years. This has already been well documented for agricultural areas. In forests, however, temporal trends are mostly studied for insect species that are considered pests. Now, a research team has studied the trends of very many insect species in German forests. Contrary to what the researchers had suspected, the results showed that the majority of the studied species are declining.

Limiting warming to 2°C may avoid 80% of heat-related deaths in Middle East and North Africa      (via sciencedaily.com)     Original source 

Over 80% of predicted heat-related deaths in the Middle East and North Africa (MENA) by the end of the century could be prevented if global warming is limited to 2°C, according to a modelling study.
