Comparative Analysis of Cytotoxic Effects of Caffeine and Theobromine in HEK293a Cells

This study was conducted to determine whether theobromine could be a less addictive, yet effective alternative to caffeine. 0.1mM Caffeine and theobromine were added to separate plates containing HEK293a and were incubated for 48 hours to observe the number of alive/dead cells on each plate. It was hypothesized that theobromine will yield less cytotoxic effects …

Levels of Programming Language

Maths, Uncategorized / By ergoscience

Programming is a set of codes to give instructions to the computer. Unlike us, computers don’t understand human languages. Therefore, we need to write a program that computers could understand. For example, Python, Java, and C++ are widely used. These languages are written in alphabets which is still understandable for us.

Fuel Cells

Chemistry, Uncategorized / By ergoscience

Unlike a battery, it does not store chemical or electrical energy; a fuel cell allows electrical energy to be extracted directly from a chemical reaction. When referring to fuel cells, the most commonly mentioned type is the PEM (Proton Exchange Membrane) cell. This cell uses hydrogen gas (H2) and oxygen gas (O2) as fuel to make electricity and water vapor. Oxygen is readily available in the atmosphere and hydrogen is gathered through the process of electrolysis of water.
