A new capability to detect chemical weapons involves two existing methods
A new capability to detect chemical weapons involves two existing methods Stephanie Baum Scientific Editor Robert Egan Associate Editor In the aftermath of suspected chemical attacks, investigators from the Organization for the Prohibition of Chemical Weapons (OPCW) step in to collect chemical, environmental, and biomedical samples. Thorough forensic laboratory analysis of these samples is essential for proving what—if any—chemical agents were used and verifying their identities. Researchers...
China is killing Europe’s chemicals industry. Brussels wants to intervene.
TESSENDERLO, Belgium — The European Commission is preparing new measures to prop up the EU’s chemicals industry as a wave of cheap Chinese imports pushes the sector to the brink. EU leaders will discuss a Commission effort to curb the Chinese supply glut at a summit on June 18–19. But the Brussels machinery moves slowly, and drawing up measures could take months, or even years — time Europe’s chemical manufacturers say they don’t have. “The whole chemical industry is bleeding,”...
PFAS in ski wax: Despite bans, these forever chemicals linger in wax rooms—so does their health risk
PFAS in ski wax: Despite bans, these forever chemicals linger in wax rooms—so does their health risk Robert Egan Associate Editor For more than 30 years, manufacturers of ski and snowboard waxes have used PFAS—per- and polyfluoroalkyl substances—to make skis and snowboards glide faster over snow. These synthetic chemicals were highly effective and common in competitive racing just about everywhere. Then studies began finding PFAS in human bodies, and research suggested the chemicals could...
LatentChem: From Textual CoT to Latent Thinking in Chemical Reasoning
arXiv:2602.07075v5 Announce Type: replace-cross Abstract: Current chemical large language models (LLMs) predominantly rely on explicit Chain-of-Thought (CoT) to solve complex reasoning problems. However, forcing nonverbal tacit chemical logic into discrete natural language imposes a fundamental ``modality mismatch,'' creating an artificial bottleneck for reasoning. We introduce LatentChem, a reasoning interface that decouples chemical logic from linguistic generation, enabling the model to...

'Chemical incident' sees Glasgow residents evacuated in huge emergency response
'Chemical incident' sees Glasgow residents evacuated in huge emergency response A chemical incident was reported at a property on Lenzie Terrace in Springburn, Glasgow on Sunday afternoon, with the street sealed off as emergency services including hazmat crews rushed to the scene A Glasgow street has been placed on lockdown following a "chemical incident" this evening (Sunday). Emergency services rushed to Lenzie Terrace in the Springburn area after the alarm was raised at around 3.30pm on...
US chemical tank disasters remain rare despite recent incidents, experts say
Tragedy in Washington and near-miss in California cast in sharp relief the risk of chemical spills and explosionsFor several tense days last week, tens of thousands of southern California residents were left wondering whether a 7,000-gallon chemical storage tank would either explode or spill out into the streets. The episode cast in sharp relief the risk of chemical spills and explosions that lurk behind every corner of modern life. The methyl methacrylate that recently left the city of...
Canadian accused of selling lethal chemical online pleads guilty to aiding suicide
The man pleaded guilty to 14 counts of aiding suicide in connection with the sale of a legal but potentially lethal chemical online. The chemical, sodium nitrite, was sold to customers who used it to end their lives. The man, who was arrested in 2020, was charged with aiding suicide and possession of a controlled substance. He pleaded guilty to the charges and was sentenced to 14 years in prison. The case highlights the dangers of online sales of potentially lethal chemicals and the need for stricter regulations to prevent such incidents.
Lignin to adipic acid in a high-yield chemical and biological redox process
Abstract Viable manufacturing pathways to produce bio-based chemicals from renewable feedstocks, such as lignin derived from plant biomass, are needed to decarbonize the chemicals manufacturing sector. Converting the recalcitrant lignin polymer to valuable bioproducts remains a longstanding challenge in biorefining, with the highest reported single-product yield from lignin currently around 20 wt% (refs. Most existing lignin depolymerization strategies target aryl–ether bond cleavage, which...
Did this star eat its planets? A new study offers clues on 'chemical paradox' of a binary system
June 5, 2026 report Did this star eat its planets? A new study offers clues on 'chemical paradox' of a binary system Shreejaya Karantha Author Lisa Lock Scientific Editor Robert Egan Associate Editor Astronomers have investigated a puzzling binary star system in which two stars that may have formed together now show dramatically different chemical compositions.
