• Using machine learning to improve the toxicity assessment of chemicals
  

  Researchers of the University of Amsterdam, together with colleagues at the University of Queensland and the Norwegian Institute for Water Research, have developed a strategy for assessing the toxicity of chemicals using machine learning. They present their approach in an article in Environmental Sc more

• New insight into how long-banned chemicals unleash their toxicity inside the body
  

  Polychlorinated biphenyls (PCBs) were widely used in industrial and commercial products including plastics, paints, electronic equipment and insulating fluids. Their manufacture was extensively banned from the late 70s onwards due to their toxicity, however large amounts still remain in our environm more

• Artificial intelligence to help protect bees from pesticides
  

  Researchers in the Oregon State University College of Engineering have harnessed the power of artificial intelligence to help protect bees from pesticides. Cory Simon, assistant professor of chemical engineering, and Xiaoli Fern, associate professor of computer science, led the project, which involv more

The Chemistry of Petrol & The Tetraethyl Lead Story

18th May marks the date of birth of Thomas Midgley, who made significant contributions to something many of us make use of on a regular basis: petrol. Midgley was the research assistant to Charles Kettering, and the duo were responsible for the addition of the compound tetraethyl lead to petrol, an more

Chemical Warfare & Nerve Agents

It’s been a little while since the last post on chemical warfare agents on the site, in which we looked at the G series nerve agents, including sarin and tabun. The second of the two graphics looking at nerve agents focuses this time on the V series, including the infamous VX. The V series compounds more

The Chemistry of Deodorants vs. Antiperspirants

Deodorants and antiperspirants are products that the majority of us make use of everyday. The two terms aren’t interchangeable, however; there is a difference in the manner in which they act to reduce body odour. Today’s graphic is a collaboration with ACS Reactions looking at the chemical compounds more

• The Right Dose
  

  Although acute toxicity studies in animals are an indispensable prerequisite for the ­realisation of clinical trials in humans, these can only be projected to humans to a limited extent, and thus are scientifically problematic and ethically questionable. Therefore, the international regulatory authorities increasingly recommend the use of alternative in vitro methods in the framework of safety studies in accordance with the ”3R Principle“ (Replacement, Reduction, Refinement). more
