Luminous molecules      (via sciencedaily.com)     Original source 

Twisted molecules play an important role in the development of organic light-emitting diodes. A team of chemists has managed to create these compounds with exactly the three-dimensional structure that they wanted. In so doing, they are smoothing the path for new and better light sources.

Your fork could someday be made of sugar, wood powders and degrade on-demand      (via sciencedaily.com)     Original source 

Single-use hard plastics are all around us: utensils, party decorations and food containers, to name a few examples. These items pile up in landfills, and many biodegradable versions stick around for months, requiring industrial composting systems to fully degrade. Now, researchers have created a sturdy, lightweight material that disintegrates on-demand -- and they made it from sugar and wood-derived powders.

British flower study reveals surprise about plants' sex life      (via sciencedaily.com)     Original source 

A study of Britain's native flowering plants has led to new insights into the mysterious process that allows wild plants to breed across species -- one of plants' most powerful evolutionary forces.  When wild flowering plants are sizing up others they may often end up in a marriage between close relatives rather than neighbors, a new study has revealed.

Pollution monitoring through precise detection of gold nanoparticles in woodlice      (via sciencedaily.com)     Original source 

Researchers introduce a novel imaging method to detect gold nanoparticles in woodlice. Their method, known as four-wave mixing microscopy, flashes light that the gold nanoparticles absorb. The light flashes again and the subsequent scattering reveals the nanoparticles' locations. With information about the quantity, location, and impact of gold nanoparticles within the organism, scientists can better understand the potential harm other metals may have on nature.

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.

New atomic-scale understanding of catalysis could unlock massive energy savings      (via sciencedaily.com)     Original source 

In an advance they consider a breakthrough in computational chemistry research, chemical engineers have developed a model of how catalytic reactions work at the atomic scale. This understanding could allow engineers and chemists to develop more efficient catalysts and tune industrial processes -- potentially with enormous energy savings, given that 90% of the products we encounter in our lives are produced, at least partially, via catalysis.

Newly discovered probiotic could protect Caribbean corals threatened by deadly, devastating disease      (via sciencedaily.com)     Original source 

Researchers have discovered the first effective bacterial probiotic for treating and preventing stony coral tissue loss disease (SCTLD), a mysterious ailment that has devastated Florida's coral reefs since 2014 and is rapidly spreading throughout the Caribbean. The probiotic treatment provides an alternative to the use of the broad-spectrum antibiotic amoxicillin, which has so far been the only proven treatment for the disease but which runs the risk of promoting antibiotic-resistant bacteria.

Coral skeletons influence reef recovery after bleaching      (via sciencedaily.com)     Original source 

Natural disasters can devastate a region, abruptly killing the species that form an ecosystem's structure. But how this transpires can influence recovery. While fires scorch the landscape to the ground, a heatwave leaves an army of wooden staves in its wake. Storm surges and coral bleaching do something similar underwater.

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.
