Chicago—An 8 a.m. start time, 6 p.m. finish, and long walk to a far corner of Chicago’s McCormick Place Convention Center. These things did not deter attendees from the Division of Medicinal Chemistry’s perennially popular first-time disclosures session on Wednesday at the American Chemical Society Fall 2026 meeting (ACS publishes C&EN but is not involved in editorial decisions).
Woodside blue ammonia plant stumbles, though CF moves ahead
In the latest setback for low-carbon ammonia, the Australian natural gas development company Woodside Energy is launching a strategic review—which may include a sale—for its newly acquired blue ammonia plant in Beaumont, Texas. At the same time, a joint venture led by the US fertilizer maker CF Industries Holding has begun construction on a similar project in Louisiana with Japanese partners.
Chemistry in Pictures: Painting with plants
For more than 1,500 years, Osiris—Egyptian god of the afterlife and the underworld and the dead—has led a parade of deities down the side of this wooden coffin to a table of offerings presented by the deceased. A tiny fleck of pigment plucked from the procession’s decorative border has revealed a surprise in the ancient artist’s paint formulation: plant proteins.
Toxins from freshwater algae blooms can go airborne
Key Insights Freshwater algae toxins can travel through the air. Scientists, who have focused primarily on toxins in marine algae, are starting to research lakes. Airborne toxins, such as microcystins, may cause long-term health problems. Each August, Lake Erie’s fishermen develop a cough. Residents who live along the body of water, one of the Great Lakes situated between the US and Canada, feel their asthma kick up. Some have such trouble breathing that they end up in the hospital.
When water is pulled from the air in homes, pollutants come with it
For many across the globe, access to clean water is not guaranteed. In recent years, atmospheric water harvesting has started to look like a promising solution for water production. Some technologies are even being developed to pull water directly from the air inside a home or office building.
Hokkaido University student dies following hydrofluoric acid exposure
A graduate student at Hokkaido University has died after severe exposure to hydrofluoric acid (HF) during an experiment in a science faculty building, the university announced Aug. 27. Two students who attempted to rescue the victim sustained minor injuries but are in stable condition. HF is uniquely hazardous because of its ability to penetrate skin with a delayed onset of pain. The fluoride ion binds with systemic calcium and can cause severe tissue destruction or fatal cardiac arrest.
Policy Watch: EPA proposal on data center air permits comes under fire
NGOs reject EPA proposal that could end public input on data center air permits An aerial shot of several large buildings with roads on two sides and other buildings in the background. A data center in Ashburn, Virginia, July 16, 2023. The US Environmental Protection Agency has proposed allowing states to determine public input requirements for air permits for data centers and certain other facilities.
As clinical trials surge into Australia, HHS targets US bottlenecks
Key Insights The number of Phase 1 clinical trials launched in Australia has skyrocketed in recent years, largely driven by US biopharma companies seeking faster trials. In an effort to accelerate domestic Phase 1 trials, the US Department of Health and Human Services in June announced Operation TrialBlazer, with proposed measures aimed mostly at the Food and Drug Administration.
How AI is quietly reshaping chemical sciences
The AI Chemist is a column covering what artificial intelligence technologies can do now, what they could do in the future, and what they shouldn’t tackle—all written by expert contributors. Anyone working with modern artificial intelligence systems will appreciate the extraordinary pace of progress achieved over the last 2 years. In 2024, the frontier models of the time (such as OpenAI’s GPT-4 series) barely reached an IQ equivalent of 100.
