RNA’s mysterious folding process — ScienceDaily

A new Northwestern University-led study is unfolding the mystery of how RNA molecules fold themselves to fit inside cells and perform specific functions. The findings could potentially break down a barrier to understanding and developing treatments for RNA-related diseases, including spinal muscular atrophy and perhaps even the novel coronavirus. “RNA folding is a dynamic process […]

Manufacturing process of ultra-thin sensor for smart contact lenses — ScienceDaily

Smart contact lenses could soon become mainstream thanks to a new manufacturing process that has allowed researchers to develop a multifunctional ultra-thin sensor layer. In a paper published by the journal Matter, engineers from the University of Surrey together with partners from Harvard University, University of Science and Technology of China, UK National Physical Laboratory, […]

Study revealing the secret behind a key cellular process refutes biology textbooks

COLUMBUS, Ohio – New research has identified and described a cellular process that, despite what textbooks say, has remained elusive to scientists until now – precisely how the copying of genetic material that, once started, is properly turned off. The finding concerns a key process essential to life: the transcription phase of gene expression, which […]

New solvent-based recycling process could cut down on millions of tons of plastic waste — ScienceDaily

Multilayer plastic materials are ubiquitous in food and medical supply packaging, particularly since layering polymers can give those films specific properties, like heat resistance or oxygen and moisture control. But despite their utility, those ever-present plastics are impossible to recycle using conventional methods. About 100 million tons of multilayer thermoplastics — each composed of as […]

New solvent-based recycling process could cut down on millions of tons of plastic waste

The solvent-targeted recovery and precipitation (STRAP) process recycles multilayered plastic waste into pure, reusable plastic materials, such as polyethylene (PE), ethylene vinyl alcohol (EVOH), or polyethylene teraphthalate (PET).

Closing the plastic loop with a one-pot recycling process

Image credit: Hans Braxmeier from Pixabay When we started using plastics about 70 years ago, not much thought — if any — was given to the implications of their lifespan and the fact that they can take centuries to decompose. Consequently, as plastics have diversified and become easier to manufacture, the planet is now straddling […]
