Aromatics cause swelling in rubber and plastic gaskets, O-rings, and hoses in airplanes, so those parts are sized and engineered accordingly. Take the aromatics away, and the parts shrink and start leaking. Because most routes to SAF don’t make aromatics, for now, airplanes are allowed to fly on no more than 50% SAF.

We should share experiments with as many people as possible, of all ages, sizes, races, backgrounds, cultures, and abilities. This is the goal of outreach! The work of the American Chemical Society Committee on Community Activities is centered around these goals. Our vision is to promote understanding and appreciation of chemistry, and our mission is to support the global chemistry community through engaging outreach, resources, training, and recognition.

“Bite-size changes that are digestible lead to asking more questions like, ‘What’s next—what else can I do?” he says. Minimizing the usage and waste of toxic and environmentally harmful reagents remains a taller order. Some chemicals, such as radioisotopes or mutagens, pose a direct risk to humans, animals, and the environment and are considerably difficult and expensive to dispose of safely.

But the uniformity of Gonzales’s injuries hinted at a different cause: the babysitter kept exotic pets, and bites from venomous animals can turn skin black and blue. Unable to search the babysitter’s home, police requested help from the local scientific community to identify potential toxins in blood and urine samples collected from the child’s body.

This year, Bryan Shaw and colleagues at Baylor University proposed a new kind of aid: bite-size and detailed models of complex structures that students can feel with their lips and tongue (Sci. Adv. 2021, DOI: 10.1126/sciadv.abh0691). Since the mouth is more sensitive to touch than fingers, Shaw’s group wanted to see if the oral sense of touch could help students perceive structures.

CRISPR gene editing also has the same packaging-size restrictions as gene therapy and carries the risk of making permanent problematic changes to DNA. In 2017, Prashant Mali’s lab at the University of California San Diego published early work describing how suppressor tRNAs and another technology called RNA editing could be a “genomically scarless” alternative to gene editing—a bold claim from a scientist who in 2013 became among the first to test CRISPR on human cells in the lab.

—Protein models are literally on the tips of students’ tongues “Bite-size molecular models could lower barriers to learning chemistry for students who are blind or visually impaired” Many chemistry and biochemistry textbooks include thousands of pictures of molecules. These images help many students learn to recognize molecules and the structural features that affect their properties.

Bite-size memories Cooking, chemistry, and Twitter intersected in a different way for chemist David K. Smith of the University of York. His new cookbook—a first for him—is Tw-eat, which Smith describes as a cookbook and a memoir. The project started as a collection of recipes for the family of his late husband, Sam, and for Smith and Sam’s son.
