A highly efficient, wearable self-charging power system is reported, which consists of a triboelectric nanogenerator (TENG) with fabric coated by MXene paste as conductive layer and micro-supercapacitors (MSCs) with graphene films as electrode.

In a study now published in iScience, researchers from the University of Vienna (Austria), National Institute of Technology - Wakayama College (NITW; Japan), and Shimane University (Japan) present the largest cephalopod genome sequenced to date. Their analyses show that the vampire squid has retained parts of an ancient, squid-like chromosomal architecture, and thus revealing that modern octopuses evolved from squid-like ancestors.

Using a deep learning AI model, researchers identified the first-of-its-kind biomarker of chronic stress detectable through routine imaging, according to research being presented next week at the annual meeting of the Radiological Society of North America (RSNA).

Kyoto, Japan -- It's astonishing to realize how innovative our ancestors were in food and beverage production before modern science and technology. Without understanding or isolating them, ancient peoples made use of yeasts like Saccharomyces cerevisiae, the primary species behind the fermentation process that creates alcohol, though there are some non-Saccharomyces yeasts that can also produce alcohol with different characteristics.

While modern wineries typically use cultured S cerevisiae, it is thought that ancient wine production relied on the natural fermentation process of storing crushed grapes in jars. However, research has revealed that S cerevisiae rarely colonizes grape skins, casting doubt on the use of fresh grapes for alcohol fermentation.

This inspired a team of researchers from Kyoto University to investigate the humble raisin's ability to ferment into wine. In a previous study, the team had found that S cerevisiae was abundant on raisins, indicating that in ancient times they could have been used for wine production.

Research teams from Swinburne University of Technology and University of Southern Queensland have provided a deep overview of the current state of the art of fire-retardant recyclable epoxy systems (FRREs) based on covalent adaptable networks. By integrating dynamic covalent bonds (DCBs) and flame-retardant groups into the epoxy crosslinking network can effectively improve fire safety and recyclability. However, how to balance the recyclability, flame retardancy, and network stability of FRREs remains a key challenge. This review provides valuable insights into the directional design of high-stability FRREs.

A joint research team led by Dr. Hee-Eun Song of the Photovoltaics Research Department at the Korea Institute of Energy Research (President Yi Chang-Keun, hereafter “KIER”) and Prof. Ka-Hyun Kim of the Department of Physics at Chungbuk National University (President Koh Chang-Seup, hereafter “CBNU”) has successfully identified, for the first time, the specific types of defects responsible for efficiency loss in silicon heterojunction (SHJ) solar cells. The findings are expected to significantly contribute to improving solar cell efficiency when combined with defect-suppression (passivation) techniques.
