A greener approach to finishing fabrics

A new method that chemically alters seed oil from the cotton plant to create an alternative to current finishing agents based on formaldehyde or per- and polyfluoroalkyl substances (PFAS) has been presented.

The new material is epoxidised cottonseed oil (ECSO). The ECSO molecules bond strongly to each other, forming a hydrophobic polymer that repels water and avoids wrinkling.

Less than 10% of plastics are produced using recycled materials

An analysis of the global plastics industry shows that only 9.5% of plastic was made from recycled materials in 2022. Almost a third of plastic waste produced during that year was allocated for recycling, but only half was actually recycled.

PFAS in fertilisers blamed for killing livestock in Texas and wreaking havoc

Synagro fertiliser made from biosolids (municipal wastewater-treated sewage sludge from the city of Fort Worth, Texas) has been blamed, as these kind of fertilisers have been known to contain PFAS-contaminated biosolids.

  Nanopore sequencing is a new protein sequencing method, which uses a biological motor to pull a protein through a tiny nanopore.

This method can detect post-translational modifications, including phosphorylation, in full-length protein structures at single molecule resolution.
