By Bridget Heos

This new addition to the Scientists in the Field series spotlights Randy Lewis, who is at the forefront of researching golden orb weaver spiders' silk. There are many potential uses for spider silk, because it is so strong and flexible. It can be used for fishing line, or even parachute rope and bulletproof vests. The most interesting part of this research is that there are experiments happening with goats! Scientists are studying the effects of implanting the spiders' silk gene into goats, and then processing the silk proteins out of their milk. One of the labs is local, at Utah State University. There are similar studies being done with transgenic silkworms and alfalfa, so it remains to be seen who will reign supreme in mass silk production. Stronger than Steel has the potential to be used for science fair projects, as there is a lot of great information and a very cool experiment for separating the DNA from a strawberry.

Review: The Factory

By
The Factory By Catherine Egan New York, NY : Scholastic Inc., 2025. Fiction. 306 pages.  Thirteen-year-old Asher Doyle has been invited to join the Factory, a secretive research facility in the desert which ostensibly extracts renewable energy from the electromagnetic fields of its young recruits. But Asher soon realizes something sinister is going on. Kids are getting sick. The adults who run the Factory seem to be keeping secrets. And the extraction process is not only painful and exhausting, but existentially troubling. Asher makes a handful of new friends who help him with an investigation that turns into a resistance, which turns into...a cliffhanger! The Factory is a page-turning sci-fi with multidimensional characters, an intriguing plot, and refreshingly straight-forward writing. Egan weaves in detail about climate crises and social unrest, making the story's dystopian setting feel rich and plausible. With its sophisticated themes and accessible storytelling, I would recomm...
