Taco-shaped arthropod fossils gives new insights into the history of the first mandibulates      (via sciencedaily.com)     Original source 

Palaeontologists are helping resolve the evolution and ecology of Odaraia, a taco-shaped marine animal that lived during the Cambrian period. Fossils reveal Odaraia had mandibles. Palaeontologists are finally able to place it as belonging to the mandibulates, ending its long enigmatic classification among the arthropods since it was first discovered in the Burgess Shale over 100 years ago and revealing more about early evolution and diversification.

Butterflies accumulate enough static electricity to attract pollen without contact      (via sciencedaily.com)     Original source 

Butterflies and moths collect so much static electricity whilst in flight, that pollen grains from flowers can be pulled by static electricity across air gaps of several millimeters or centimeters.

Best bioenergy crops for sustainable aviation fuels by U.S. region, policy goals      (via sciencedaily.com)     Original source 

Researchers analyzed the financial and environmental costs and benefits of four biofuels crops used to produce sustainable aviation fuels in the U.S. They found that each feedstock -- corn stover, energy sorghum, miscanthus or switchgrass -- performed best in a specific region of the rainfed United States. Their study will help growers and policymakers select the feedstocks most suited to meeting goals like reducing production costs, lowering greenhouse gas emissions and building soil carbon stocks.

Children's exposome associated with changes in serum metabolites      (via sciencedaily.com)     Original source 

The combined effect of environmental exposures and unhealthy lifestyle habits can affect children's cardiometabolic health in a way that exceeds their separate effects. A new study shows the benefit of measuring the combined effect of multiple environmental and lifestyle factors.

Converting captured carbon to fuel: Study assesses what's practical and what's not      (via sciencedaily.com)     Original source 

A new analysis sheds light on major shortfalls of a recently proposed approach to capture CO2 from air and directly convert it to fuel using electricity. The authors also provide a new, more sustainable, alternative.

Deep-ocean floor produces its own oxygen      (via sciencedaily.com)     Original source 

An international team of researchers has discovered that metallic minerals on the deep-ocean floor produce oxygen -- 13,000 feet below the surface. Discovery challenges long-held assumptions that only photosynthetic organisms generate Earth's oxygen. Minerals at the abyssal seafloor appear to act like geobatteries to produce oxygen in a process that does not require sunlight.

Waste Styrofoam can now be converted into polymers for electronics      (via sciencedaily.com)     Original source 

A new study describes a chemical reaction that can convert Styrofoam into a high-value conducting polymer known as PEDOT:PSS. Researchers also noted that the upgraded plastic waste can be successfully incorporated into functional electronic devices, including silicon-based hybrid solar cells and organic electrochemical transistors.

New snake discovery rewrites history, points to North America's role in snake evolution      (via sciencedaily.com)     Original source 

A new species of fossil snake unearthed in Wyoming is rewriting our understanding of snake evolution. The discovery, based on four remarkably well-preserved specimens found curled together in a burrow, reveals a new species named Hibernophis breithaupti. This snake lived in North America 34 million years ago and sheds light on the origin and diversification of boas and pythons.

Converting wastewater to fertilizer with fungal treatment      (via sciencedaily.com)     Original source 

Creating fertilizers from organic waste can help reduce the consumption of fossil fuels and promote sustainable production. One way of doing this is through hydrothermal liquefaction (HTL), which converts biomass into biocrude oil through a high-temperature, high-pressure process. Two studies explore the use of a fungal treatment to convert the leftover wastewater into fertilizer for agricultural crops.

Small animals acquire genes from bacteria that can produce antibiotics      (via sciencedaily.com)     Original source 

A group of small, freshwater animals (bdelloid rotifers) protect themselves from infections using antibiotic recipes 'stolen' from bacteria, according to new research. This raises the potential that rotifers are producing novel antimicrobials that may be less toxic to animals, including humans, than those we develop from bacteria and fungi.

Minerals play newly discovered role in Earth's phosphorus cycle      (via sciencedaily.com)     Original source 

Plants and microbes are known to secrete enzymes to transform organic phosphorus into bioavailable inorganic phosphorus. Now, researchers found that iron oxide in soil performs the same transformation. Discovery is important for food security, which requires phosphorus as a crop fertilizer.

Although tiny, peatland microorganisms have a big impact on climate      (via sciencedaily.com)     Original source 

Polyphenols are generally toxic to microorganisms. In peatlands, scientists thought microorganisms avoided this toxicity by degrading polyphenols using an oxygen-dependent enzyme, and thus that low-oxygen conditions inhibit microbes' carbon cycling. However, a new study found that Arctic peatland microorganisms used alternative enzymes, with and without oxygen, to break down polyphenols. This suggests carbon stored in these ecosystems is more at risk than previously thought.
