In the laboratory, forensic scientists analyze ink components regularly to determine what made a mark at a crime scene. In this video, we show you how to separate the different components of water-soluble markers and how to separate them with supplies at home. Video can be paused on supplies page for you to gather the necessary materials! Credit to Chaminade University I Am A Scientist for the production of this video.
This video shows an experiment attempting to make two batches of ice cream – one will work and one will not. The video shows you step by step instructions to try at home and a supply list you can pause to gather materials in advance. Have fun using chemistry at home!

In the search and recovery of human remains during mass disasters, homicides, and missing persons investigations, the odor evolved from decomposing bodies is crucial in the search process. One contributor to the odor evolved from remains are microorganisms, which contribute a portion of the chemicals released into the air. New technology is being used to profile the odor from postmortem microbes to improve techniques that rely on the detection of decomposition odor. Katelynn Perrault, PhD, (University of Honolulu) discusses the challenges of odor detection in forensic science and the benefits of 2D gas chromatography over conventional 1D gas chromatography.
Katelynn Perrault participates in Thermo Fisher Scientific’s celebration of International Women’s Day! We dedicate this post to all the fabulous women out there who shine bright and make the world a better place through science.
