First ever reported cryo-EM visualization of E. coli TGT structure

The enzyme tRNA-guanine transglycosylase (TGT) chemically modifies transfer RNA (tRNA) and plays a key role in how disease-causing bacteria control the production of proteins needed to cause infection. E. coli TGT is nearly identical to the one found in Shigella, which causes the

How 'super' enzymes can transform recycling

From microplastics clogging up our oceans to landfills leaching dangerous chemicals, plastic waste is a serious and growing problem for human health and the environment. We need to recycle more and, crucially, recycle better.

2% minimum tax on richest households could raise £10 billion

Introducing a 2% minimum annual tax on households with more than £100 million in wealth could raise around £10 billion in 2026, while affecting fewer than 1,000 households in the UK, suggests a report by academics at King's College London, the Paris School of Economics and the Un

Hydra rebuilds the body by restoring its internal cellular map

Before a hydra can regrow a head or foot, its cells appear to rebuild the internal map that tells them where they are and what they should become next, FMI researchers report. The work suggests that cells need to interpret not only where they are in the body, but also what stage

Scientists revive a powerful antibiotic that superbugs had defeated

Scientists have found a way to revive vancomycin, a powerful antibiotic that some dangerous bacteria have learned to resist. Instead of creating an entirely new drug, researchers paired vancomycin with a small molecule called pghi-4, which blocks a bacterial enzyme linked to resi

Reusable magnetic invention removes microplastics plus some PFAS from water

Microplastics are an increasing global concern, with growing evidence of their presence in water systems. RMIT University researchers have developed a water treatment material that rapidly removes micro- and nanoplastics and some PFAS (per- and polyfluoroalkyl substances), bringi

AI and quantum chemistry combine to identify efficient blue OLED materials

Organic light-emitting diodes (OLEDs) have become a standard in modern devices with incredible contrast and sleek designs. While initially an expensive luxury, OLEDs are gradually becoming more financially accessible as the technology improves. Now, researchers at the Institute o
