Biology
Surface Area to Volume Ratio Calculator
Calculates the surface area to volume ratio of a spherical cell given its radius. Essential in cell biology to understand nutrient exchange efficiency and why cell size is limited.

Biology
Gene Expression Fold Change Calculator
Quantify how much a gene is up- or down-regulated between two conditions using the 2^(−ΔΔCt) method from qRT-PCR data. Use this when comparing treated vs. control gene expression levels.
