Distribution of the human OH field when a lotion or a fragrance is applied in the room. Human OH field with lotion (A and B) and fragrance (C and D). Spatial distributions of OH reactivity and gas-phase species under two conditions: (A) and (B) represent the scenario where lotion was applied to the exposed skin of four occupants, observed at 60 and 600 s, respectively, after O3 was introduced into the room from a perforated inlet on the floor. (C) and (D) depict the scenario where a fragrance was applied to the back of the hands of two occupants sitting in the chamber, observed at 40 and 90 s, respectively, after the fragrance application.

Perfume and Lotion Are Quietly Changing the Air You Breathe Indoors

Hierarchical architecture of El Agente Q. Inter-agent communication is illustrated with black arrows, where solid arrows represent task delegation from higher-level agents, and dotted arrows indicate feedback and reporting from lower-level agents. The agents can be broadly categorized into three functional modules- the geometry module (coral), the quantum calculation module (blue), and the file I/O module (yellow). Each module can be thought of as a department in a complex organization with its own manager, employees, and tools (violet). For example, the geometry generation agent gets to decide if the system should be handled by the organometallic complexes agent or Perplexity AI search, and decide the charge and multiplicity of the system.

Blue electrolyte-to-golden metal transition in solutions of lithium in liquid ammonia. Computer simulations predict that at intermediate concentrations the system by itself rapidly flips back and forth between a low conductivity electrolyte (blue) and a high conductivity metal (gold).

Quantum Leap in Chemistry as Molecules Reveal Their Dance with Light

The researchers' de novo protein design workflow begins with using a helical bundle as a framework for the new protein, left, using AI to design the amino acid sequences required for the desired protein structures, X-ray crystallography to assess the resulting protein structure, and further refinement to the design using tried-and-true methods and 'chemical intuition," until the optimal design is reached, right.

During the formose reaction, formaldehyde molecules (red) spontaneously and repeatedly react with each other to create larger molecules. Scripps Research scientists show that this reaction does not result in the production of linear sugars, like ribose (pink), which are the essential building blocks of life. Credit: Scripps Research
