Solid state battery design charges in minutes, lasts for thousands of cycles      (via sciencedaily.com)     Original source 

Researchers have developed a new lithium metal battery that can be charged and discharged at least 6,000 times -- more than any other pouch battery cell -- and can be recharged in a matter of minutes. The research not only describes a new way to make solid state batteries with a lithium metal anode but also offers new understanding into the materials used for these potentially revolutionary batteries.

Bottled water can contain hundreds of thousands of previously uncounted tiny plastic bits      (via sciencedaily.com)     Original source 

In recent years, there has been rising concern that tiny particles known as microplastics are showing up basically everywhere on Earth, from polar ice to soil, drinking water and food. Formed when plastics break down into progressively smaller bits, these particles are being consumed by humans and other creatures, with unknown potential health and ecosystem effects. One big focus of research: bottled water, which has been shown to contain tens of thousands of identifiable fragments in each container. Now, using newly refined technology, researchers have entered a whole new plastic world: the poorly known realm of nanoplastics, the spawn of microplastics that have broken down even further. For the first time, they counted and identified these minute particles in bottled water. They found that on average, a liter contained some 240,000 detectable plastic fragments -- 10 to 100 times greater than previous estimates, which were based mainly on larger sizes.

A novel strategy for extracting white mycelial pulp from fruiting mushroom bodies      (via sciencedaily.com)     Original source 

Mycelial fibers, the fibrous cells found in fruiting mushroom bodies, have gained momentum as a sustainable material for making faux-leather and packaging owing to their excellent formability. Recently, a team of researchers has found a simple way of obtaining mycelial fibers, called 'mycelial pulp,' from fruiting mushroom bodies and bleaching them using sunlight while keeping their mycelial structures intact.

Advancing the generation of in-vivo chimeric lungs in mice using rat-derived stem cells      (via sciencedaily.com)     Original source 

Creating a functional lung using interspecies chimeric animals is an attractive albeit challenging option for lung transplantation, requiring more research on the viable conditions needed for organ generation. A new study uses reverse-blastocyst complementation and tetraploid-based organ complementation methods to first determine these conditions in lung-deficient mice and then to generate rat-derived lungs in these mice. It provides useful insights on the intrinsic species-specific barriers and factors associated with lung development in interspecies chimeric animals.

High-performance stretchable solar cells      (via sciencedaily.com)     Original source 

Engineers have succeeded in implementing a stretchable organic solar cell by applying a newly developed polymer material that demonstrated the world's highest photovoltaic conversion efficiency (19%) while functioning even when stretched for more than 40% of its original state. This new conductive polymer has high photovoltaic properties that can be stretched like rubber. The newly developed polymer is expected to play a role as a power source for next-generation wearable electronic devices.

Nematode proteins shed light on infertility      (via sciencedaily.com)     Original source 

Biologists developed a method for illuminating the intricate interactions of the synaptonemal complex in the nematode C. elegans. The authors identified a trio of protein segments that guide chromosomal interactions, and pinpointed the location where they interact with each other. Their novel method uses a technique known as genetic suppressor screening, which can serve as a blueprint for research on large cellular assemblies that resist traditional structural analysis.
