Self-dyeing vegan leather made by genetically engineered bacteria

Genetically engineered bacteria have been designed to produce self-dyeing, vegan, plastic-free leather. The work, carried out by UK-based researchers, could offer a more sustainable alternative to traditional leather and the associated chemical dyeing processes. ‘By 2050, after food and construction, materials for textiles and fabrics will be the third biggest polluter in the world – […]

First entirely roll-to-roll system points way to cheap printed perovskite solar cells

A new roll-to-roll system that can print perovskite solar cells could streamline the scale-up of the technology. ‘It marks a pivotal milestone in the field, showcasing the potential for the cost-effective production of high-performance solar cells,’ says lead author Doojin Vak from CSIRO Manufacturing in Victoria, Australia. ‘This breakthrough suggests the possibility of producing large-scale […]

Chemists and linguists unite to encode Confucian proverb using sequence-defined polymers

A unique collaboration between chemists and linguists links linguistic considerations with information storage for the first time. The interdisciplinary project has resulted in the successful encryption and subsequent decryption of a Confucius proverb in both Unicode and Zhèng Mă using sequence-defined polymers.1 DNA, the most famous naturally occurring information storage polymer, stores vast amounts of […]

A key chemistry journal disappeared from the web. Others are at risk

When Jonathan Goodman went looking for a paper published by the popular chemistry journal Heterocycles, he realised something odd. Not only was the paper he was looking for not available, all of the journal’s content had disappeared from the web. ‘I was looking for an article in Heterocycles because it’s a journal which contains a lot of […]

Telling left from right: chirality detection faces up to its weaknesses

Like Oscar Wilde’s Dorian Gray there are many molecules with a sinister mirror image twin. Failure to recognise the distinct properties of a molecule’s mirror image version can have tragic consequences, as demonstrated by the thalidomide scandal in the 1950s and 1960s. Chiral molecules interact with other chiral structures differently from their mirror image twin […]

US government scientists follow academics in unionising for better conditions

An organisation representing nearly 6000 professional scientists working for the US state of California has voted to affiliate to the nationally organised United Auto Workers (UAW). The decision follows the trend of academic researchers and scientists in the US unionising to improve their working conditions following several high-profile and successful strikes at major research universities […]

First mirror-image cyclodextrins come together ‘like Lego’

The first L-cyclodextrins have been synthesised in the lab – these rings of six to eight sugar units are the mirror-image structures of more common D-cyclodextrins. Fraser Stoddart’s team at Northwestern University in the US used a straightforward one-pot strategy to make the substances in half-gram amounts. ‘We have made L-cyclodextrins in a very efficient and scalable manner,’ […]
