Young Scientist Reveals Hidden Dangers in Pet Food Preservatives

Mackensey Wilson, a 14-year-old aspiring veterinarian, investigated the presence of the potentially harmful preservative BHT in three popular dog food brands, finding about 0.1% BHT in each, despite it not being listed on their labels. Her research, inspired by her dog's health issues, earned her a finalist spot in the 2024 Thermo Fisher Scientific Junior Innovators Challenge and a second-place Science Award. Mackensey highlights the importance of organization and encourages others to try science projects for the learning experience.

"Teen's Science Project Suggests Archimedes' Invention Was Plausible"

Brenden Sener, a 13-year-old from London, Ontario, recreated a miniature version of Archimedes' supposed "death ray" for a science project, using concave mirrors to focus light energy. His experiment showed a notable increase in temperature with each additional mirror, suggesting that the concept was plausible. While the practicality of the death ray is limited by factors such as weather and ship motion, Sener's project has garnered praise from scientists and could spark discussions among students.

"Teen recreates Archimedes' death ray for science fair experiment"

A 13-year-old Canadian student conducted a science fair project to test whether Archimedes' purported use of mirrors to set Roman ships alight was feasible. Using heat lamps and mirrors, he found that his setup significantly increased the temperature of the target, leading him to conclude that it could be possible on a larger scale. While many have attempted to recreate the "death ray" with varying success, historians and scientists have suggested alternative weapons that Archimedes may have used.
