Researchers have shed new light on the fundamental mechanisms of heat dissipation in graphene and other two-dimensional materials. They have shown that heat can propagate as a wave over very long distances. This is key information for engineering the electronics of tomorrow.

Today, touch screens are everywhere, from smart phones and tablets, to computer monitors, to interactive digital signage and displays. Many touch screens are made of layered thin (billionths of a meter thick) films of indium-tin oxide, an inorganic material that is electrically conductive, which allows electrical signals to travel from the "touch" to the edges of the display, where they are sensed by the device--as well as optically transparent. But these and other inorganic materials have a downside, as anyone who has ever dropped their smart phone knows: they are brittle and shatter easily. The solution? Make the screens flexible and durable without sacrificing any of their electrical or optical properties. Researchers have now created thin sheets of hybrid materials that may enable the next generation of consumer electronics.

Researchers observed that the coiling action of the butterfly proboscis, a tube-like 'mouth' that many butterflies and moths use to feed on fluids, resembled a spiral similar to that of the Golden Ratio, and decided to investigate.

For once, slower is better in a new piece of technology. Scientists have developed a new, radio frequency processing device that allows information to be controlled more effectively, opening the door to a new generation of signal processing on microchips. One of the keys to the technology involves slowing information down.

Moves are being made to automate the identification of Saimaa ringed seals. This would bring new kinds of real-time information on how the extremely endangered species behaves, the movements of individual seals, and what happens to them. The final aim of an ongoing study on machine vision is to get a biometric passport for each individual Saimaa ringed seal. This happens on the basis of the unique fur patterns of each individual seal, using computer-based smart calculation and digital image processing. The aim is to store the information in a so-called Saimaa ringed seal database.

Women with alcoholic partners who face barriers to seeking help may benefit from an Internet-based, interactive support program, a study concludes. Approximately 7.7 million U.S. adults are currently married to or living with a partner with an alcohol use disorder. The burden of living with an alcoholic partner can cause considerable psychological distress, but many spouses do not or cannot seek help.

A study to better understand the factors influencing the spread of conservation news in online media has been concluded. Public awareness is often a crucial first step towards policy change and resolution of conservation issues because societal values determine whether initiatives gain support. There is evidence that public engagement positively influences civic participation. Therefore, conservation science needs to engage the general public to ensure successful conservation interventions, researchers say.
