Chemists at the University of Bristol analyzed the air around tiny fragments of Egyptian mummies to identify volatile organic compounds linked to embalming materials. The study, covering remains from 3200 BC to 395 AD, found 81 distinct compounds from oils, resins, beeswax, and bitumen. These clues show mummification practices grew more complex over time.

A new analysis indicates that two key quantum computing algorithms for chemistry problems have limited practical use, even with advancing hardware. Researchers suggest that calculating molecular energy levels may not justify the technology's investment as hoped. This challenges the view of quantum chemistry as a major application for quantum computers.

Researchers at the University of California, Los Angeles, have synthesized cage-shaped molecules featuring unusually warped double bonds, defying long-held principles of organic chemistry. This breakthrough builds on their 2024 overturning of Bredt's rule and could influence future drug design. The findings appear in Nature Chemistry.

A new study suggests that hydrogen cyanide, a highly poisonous chemical, could have played a key role in the origins of life by forming reactive ice crystals in extreme cold. Computer simulations show these crystals promote unusual chemical reactions that produce building blocks for life. The findings highlight the chemical potential of frozen environments, including those beyond Earth.

Zwei Arbeiter sind gestorben und zwei weitere wurden bei der Explosion am Montag im Werk Elkem Silicones in Saint-Fons bei Lyon verletzt. Die Gewerkschaften CGT und CFDT kündigten an, sich als Nebenkläger in der Untersuchung wegen fahrlässiger Tötung zu stellen, und bezeichneten den Vorfall als 'untragbar'.

Google DeepMind's AlphaFold artificial intelligence system has marked its fifth anniversary, continuing to evolve after revolutionizing biology and chemistry. The project earned the Nobel Prize in Chemistry last year for its groundbreaking contributions. WIRED recently discussed its trajectory with DeepMind's Pushmeet Kohli.
