This project tests whether an indoor cabinet garden can reduce grocery costs for Calgary families. Using a display cabinet with LED lights, I will grow microgreens and small vegetables, meas…
AJAS · 2026
Microbiology (inferred)
Infections caused by the bacteria Staphylococcus aureus are common and dangerous, and antibiotic treatments may not be available or appropriate in all cases. This creates the need for afford…
ISEF · 2026
Energy: Sustainable Materials and Design
The transition to a circular carbon economy is hindered by the low energy density of current storage and the inefficiency of biological carbon sequestration. The GSFG-Omni addresses this by…
ISEF · 2026
Biomedical Engineering
Neurocardiological emergencies claim over 18 million lives every year. With out-of-hospital survival dropping 10% every delayed minute, intervening early is critical. However, generalized ph…
