Scientists have created new way to characterise graphene oxide (GO) cheaper and quicker than ever before, helping get the emerging technology out of the lab and into the market. 

Groundbreaking research led by a Swansea University academic has revealed a synthetic glycosystem — a sugar-coated polymer nanoparticle — that can block Covid-19 from infecting human cells, reducing infection rates by nearly 99%.

A UNSW analysis of Sydney water has found at least 31 PFAS chemicals, including 21 not previously recorded in Australian tap water, and one detected in tap water globally for the first time.

Per- and polyfluoroalkyl substances (PFAS), or forever chemicals, are being identified in more places. Period products are on that list, likely because of the resistance to stains and liquids conferred by these chemicals. Building on previously presented research, a team publishing in ACS’ Environmental Science & Technology Letters found that some reusable products, namely period underwear and reusable pads, contained PFAS, which might be absorbed into the body through skin contact.
