Thousands of small, time sensors that secure time can collectively map chemical concentration in a narrow tube.
The human intestinal system (A) can be represented as a series of plugflow reaction devices (B), a model that describes a chemical reaction in the flowing cylindrical system. Time recognition particles (C) pass through the plugflow system and detect interest chemicals known as analysis. Credit: Manion et al. , 2025. A diagram made partially in a violence. When synthesizing chemicals,…

AI analysis shows chemical research often contains inaccurate mass measurement data
Examples of accurate mass calculations and miscalculations using ChemDraw. Credit: Organic Letters (2024). DOI: 10.1021/acs.orglett.4c03458 AI-powered data analysis tools have the potential to significantly improve the quality of scientific publications. A new study by Professor Matthias Christmann, professor of chemistry at the Free University of Berlin, reveals shortcomings in chemical publications. Christmann analyzed more than 3,000 scientific papers published in…

Environmentally friendly chlorine method could revolutionize pharmaceutical and chemical production
Gram-scale synthesis and mechanistic studies. Credit: Nature Synthesis (2025). DOI: 10.1038/s44160-024-00698-z Chlorine plays an essential role in everyday life, from keeping pools clean to preserving food. Now, a team of Rice University chemists has developed a more environmentally friendly way to incorporate chlorine into the chemical building blocks of pharmaceuticals, plastics, pesticides, and other essential products while reducing costs. The…

How chemical reactions deplete nutrients in plant-based beverages
Plant-based drinks in the lab. Credit: Jacob Helbig The global market for plant-based beverages has experienced impressive growth over the past decade, during which oat, almond, soy, and rice beverages have emerged as popular alternatives to milk in coffee and oatmeal. A possible reason why millions of liters of plant-based drinks end up in consumers’ shopping carts is because their…

Shipwreck bones suggest being right- or left-handed may influence chemical changes in the clavicle as you age
A living ship viewed from the center of the ship toward the bow. The scenery projected on the hull reflects the activities that took place in each area. The “players” are volunteers and staff, wearing copies of clothing and using replicas of artifacts. To the left is the main deck gallery containing authentic artifacts, located opposite where they were discovered…

Scientists discover chemical probe for previously ‘untreatable’ cancer target
Structural models predict that the small molecule binding site on FOXA1 is close to DNA. Credit: Scripps Research Cancers caused by hormones, such as breast and prostate cancers, often rely on a difficult-to-target protein called forkhead box protein 1 (FOXA1). FOXA1 mutations may enable these types of cancers to grow and proliferate. Currently, FOXA1 is notoriously difficult to block with…

Utilizing AI to elucidate the chemical composition of paints used in classical paintings
Restoration of the Baronchi Altarpiece by Raphael. In this work, the two paintings at the top, the Virgin Mary (left) and God the Father (right), are analyzed. The two paintings belong to the collection of the Capodimonte Museum (Naples). On the lower left is an angel holding a holy verse (Paris, Louvre Museum), and on the lower right is a…
