Multiple uses of tropical mosaic landscapes      (via sciencedaily.com)     Original source 

Many landscapes in the tropics consist of a mosaic of different types of land use. How people make use of these different ecosystems, with their particular plant communities, was unclear until now. Researchers, many of them from Madagascar, have now investigated this. When considering biodiversity, forests often get the most attention. But this research shows that rural households use a wide range of plant species and services provided by many nearby ecosystem types.

Small-winged and lighter colored butterflies likely to be at greatest threat from climate change      (via sciencedaily.com) 

Small-winged and lighter colored butterflies likely to be at greatest threat from climate change. The family, wing length and wing colour of tropical butterflies all influence their ability to withstand rising temperatures, say ecologists. The researchers believe this could help identify species whose survival is under threat from climate change.

Using AI to save species from extinction cascades      (via sciencedaily.com)     Original source 

Algorithms can predict what movies or songs you might like, but they can also predict which species a predator would most likely eat. Researchers have been using machine learning to identify species interactions, and can predict which species are most likely to go extinct, so that intervention can be planned before this happens.

Marine fossils are a reliable benchmark for degrading and collapsing ecosystems      (via sciencedaily.com)     Original source 

Humans began altering environments long before records were kept of the things that lived in them, making it difficult for scientists to determine what healthy ecosystems should look like. Researchers show the recent fossil record preserves a reliable snapshot of marine environments as they existed before humans.

Caterpillar venom study reveals toxins borrowed from bacteria      (via sciencedaily.com)     Original source 

Researchers have found toxins in the venom of asp caterpillars are completely different to anything they have seen before in insects. Toxins in the caterpillar venom punch holes in cells the same way as toxins produced by disease-causing bacteria such as E. coli and Salmonella. Venoms are rich sources of new molecules that could be developed into medicines of the future, pesticides, or used as scientific tools.

First detection of crucial carbon molecule      (via sciencedaily.com)     Original source 

Scientists detect a new carbon compound in space for the first time. Known as methyl cation (pronounced cat-eye-on) (CH3+), the molecule is important because it aids the formation of more complex carbon-based molecules. Methyl cation was detected in a young star system, with a protoplanetary disk, known as d203-506, which is located about 1,350 light-years away in the Orion Nebula.

Towards efficient lithium--air batteries with solution plasma-based synthesis of perovskite hydroxide catalysts      (via sciencedaily.com)     Original source 

CoSn(OH)6 (CSO) is an effective oxygen evolution reaction (OER) catalyst, necessary for developing next-generation lithium -- air batteries. However, current methods of synthesizing CSO are complicated and slow. Recently, an international research team synthesized CSO in a single step within 20 minutes using solution plasma to generate CSO nanocrystals with excellent OER catalytic properties. Their findings could boost the manufacturing of high energy density batteries.

Surprise! Weaker bonds can make polymers stronger      (via sciencedaily.com)     Original source 

Chemists discovered a new way to make polymers stronger: introduce a few weaker bonds into the material. Working with polyacrylate elastomers, they could increase the materials' resistance to tearing up to tenfold by using a weaker type of crosslinker to join some of the polymer building blocks.

Stronger tape engineered through the art of cutting      (via sciencedaily.com)     Original source 

What if you could make adhesives both strong and easily removable? This seemingly paradoxical combination of properties could dramatically change applications in robotic grasping, wearables for health monitoring, and manufacturing for assembly and recycling. A team has adapted kirigami, the ancient Japanese art of cutting paper, into a method for increasing the adhesive bond of ordinary tape by 60 times. Developing such adhesives may not by that far off through the latest research conducted by the team of Michael Bartlett, assistant professor in the Department of Mechanical Engineering at Virginia Tech, and published in Nature Materials on June 22.
