In considering materials that could become the fabrics of the future, scientists have largely dismissed one widely available option: polyethylene.
The stuff of plastic wrap and grocery bags, polyethylene is thin and lightweight, and could keep you cooler than most textiles because it lets heat through rather than trapping it in. But polyethylene would also lock in water and sweat, as it s unable to draw away and evaporate moisture. This antiwicking property has been a major deterrent to polyethylene s adoption as a wearable textile.

But polyethylene would also lock in water and sweat, as it’s unable to draw away and evaporate moisture. This antiwicking property has been a major deterrent to polyethylene’s adoption as a wearable textile.
Now, MIT engineers have spun polyethylene into fibers and yarns designed to wick away moisture. They wove the yarns into silky, lightweight fabrics that absorb and evaporate water more quickly than common textiles such as cotton, nylon, and polyester.

Italian and Russian researchers confirmed the hypothesis that the self-maintaining order in eukaryotic cells (cells with nuclei) is a result of two spontaneous mechanisms collaboration. Similar molecules gather into drops on the membrane and then leave it as tiny vesicles enriched by the collected molecules. The paper with the research results was published in the journal
The research was carried out by an international interdisciplinary team of biologists (from Polytechnic University of Turin, Italian Institute for Genomic Medicine of the University of Turin and Candiolo Cancer Institute) and physicists (from Landau Institute for Theoretical Physics and HSE University Faculty of Physics).
