Flexible, wearable supercapacitors based on porous nanocarbon nanocomposites
Evening gowns with interwoven LEDs may look extravagant, but the light sources need a constant power supply from devices that are as well wearable, durable, and lightweight. Chinese scientists have manufactured fibrous electrodes for wearable devices that are flexible and excel by their high energy density. A microfluidic technology was key for the preparation of the electrode material was a microfluidic technology, as shown in the journal Angewandte Chemie.

Researchers find genes that help maintain the 50-50 balance between male and female offspring in mice — and that have major implications for male infertility.

The ways climate scientists explain their predictions about the impact of global warming can either promote or limit their persuasiveness.
Read moreA new stable form of plutonium discovered
Scientists have found a new compound of plutonium with an unexpected, pentavalent oxidation state. This new phase of plutonium is solid and stable, and may be a transient phase in radioactive waste repositories.
Read moreAll plastic waste could become new, high-quality plastic through advanced steam cracking
A research group has developed an efficient process for breaking down any plastic waste to a molecular level. The resulting gases can then be transformed back into new plastics – of the same quality as the original. The new process could transform today's plastic factories into recycling refineries, within the framework of their existing infrastructure.

An easy-to-use electrode set can assess sleep bruxism severity as well as a conventional polysomnography, a new study shows.
Read moreLifestyle is a threat to gut bacteria: Ötzi proves it, study shows
The evolution of dietary and hygienic habits in Western countries is associated with a decrease in the bacteria that help in digestion. These very bacteria were also found in the Iceman, who lived 5300 years ago, and are still present in non-Westernized populations in various parts of the world. The depletion of the microbiome may be associated with the increased prevalence, in Western countries, of complex conditions like allergies, autoimmune and gastrointestinal diseases, obesity.
Preventing streptococci infections
Researchers have discovered an enzyme they believe could be key to preventing Group A Streptococcus infections that cause more than 500,000 deaths worldwide each year. The enzyme works through a novel mechanism of action that can also be found in other streptococcal species, increasing the impact and relevance of this finding.
