A non-target screening method for hazardous substances in the marine environment

Marine species with important roles in the Baltic Sea ecosystem were selected for the study, and with the help of mass spectrometry “fingerprints” of the thousands of substances present in these animals were generated. By finding substances that were present in both prey and predators, and which were present in significantly higher concentrations in the… Continue reading A non-target screening method for hazardous substances in the marine environment

Setting the standard for calculating indirect emissions | Business

A group of chemical companies has developed guidance to help industry calculate the cradle-to-gate emissions of the chemical products it purchases. Together for Sustainability – which includes global players – said the ‘first of its kind’ guideline would harmonise product carbon footprint (PCF) calculation approaches across the industry, to provide quality footprint data that are… Continue reading Setting the standard for calculating indirect emissions | Business

A method to recycle pineapple leaf fibers into filaments for 3D printing

Credit: CC0 Public Domain An international team of researchers, led by Dr. Mansingh (Sri Ramakrishna Engineering College), Dr. JS Binoj (Center for Advanced Composite Materials, Universiti Teknologi Malaysia & Institute of Mechanical Engineering, SIMATS) and Associate Professor Eugene Wong (Newcastle University in Singapore), has successfully developed a method to recycle agriculture waste, namely pineapple leaf… Continue reading A method to recycle pineapple leaf fibers into filaments for 3D printing

Call for chemists to reorientate chemistry as a sustainability science | News

Many of the world’s most used chemicals are transgressing one or more of the nine planetary boundaries. If we are to address this crisis, chemists at all levels must work to reposition chemistry as a sustainability science, an international team of scientists has said.1 Developed between 2009 and 2015, the planetary boundaries framework describes nine… Continue reading Call for chemists to reorientate chemistry as a sustainability science | News

Challenging diversity in favour of equity | Opinion

This June, I attended the 71st Lindau Nobel laureate meeting. Each year, the conference brings together young scientists from all over the world with Nobel laureates of a dedicated discipline, chemistry in this case. Many of them experienced the conference as one of the most diverse they ever attended. Indeed, many attendants belonged to structurally… Continue reading Challenging diversity in favour of equity | Opinion

Scientists Uncover the “Chemistry Behind the Origin of Life”

Chemists discover a mechanism for peptide-forming reactions to occur in water, which leads to proteins and so to life on Earth. It could also lead to the faster development of drugs to treat humanity’s most debilitating diseases. Water Droplets Hold the Secret Ingredient for Building Life Chemists uncover key to early Earth chemistry, which could… Continue reading Scientists Uncover the “Chemistry Behind the Origin of Life”

First Theorized 70 Years Ago – “Rippled Beta Sheet” Created for the First Time

The rippled beta sheet is a variation of the pleated beta sheet, a well-known structural motif found in thousands of proteins. Linus Pauling and Robert Corey described the rippled beta sheet in 1953, but it remained a largely theoretical structure for decades. Scientists have now created rippled sheets in the laboratory and characterized the structure… Continue reading First Theorized 70 Years Ago – “Rippled Beta Sheet” Created for the First Time

Stretchy, bio-inspired synaptic transistor can enhance, weaken device memories — ScienceDaily

Robotics and wearable devices might soon get a little smarter with the addition of a stretchy, wearable synaptic transistor developed by Penn State engineers. The device works like neurons in the brain to send signals to some cells and inhibit others in order to enhance and weaken the devices’ memories. Led by Cunjiang Yu, Dorothy… Continue reading Stretchy, bio-inspired synaptic transistor can enhance, weaken device memories — ScienceDaily

Research team achieves breakthrough in the production of an acclaimed cancer-treating drug

Credit: Paul A. Wender et al, Nature Chemistry (2022). DOI: 10.1038/s41557-022-01048-2 Stanford University researchers have discovered a rapid and sustainable way to synthetically produce a promising cancer-fighting compound right in the lab. The compound’s availability has been limited because its only currently known natural source is a single plant species that grows solely in a… Continue reading Research team achieves breakthrough in the production of an acclaimed cancer-treating drug

Chemists discover key to early Earth chemistry, which could unlock ways to speed up chemical synthesis for drug discovery — ScienceDaily

Purdue University chemists have uncovered a mechanism for peptide-forming reactions to occur in water — something that has puzzled scientists for decades. “This is essentially the chemistry behind the origin of life,” said Graham Cooks, the Henry Bohn Hass Distinguished Professor of Analytical Chemistry in Purdue’s College of Science.”This is the first demonstration that primordial… Continue reading Chemists discover key to early Earth chemistry, which could unlock ways to speed up chemical synthesis for drug discovery — ScienceDaily
