How does the 1st and 2nd law of thermodynamics apply to biological systems?
How does the 1st and 2nd law of thermodynamics apply to biological systems? Two fundamental concepts govern energy as it relates to living organisms: the First Law of Thermodynamics states that total energy in a closed system is neither lost nor gained — it is only transformed. The Second Law of Thermodynamics states that entropy […]
Do you think humans are still evolving?
Do you think humans are still evolving? Takeaway: Evolution means change in a population. That includes both easy-to-spot changes to adapt to an environment as well as more subtle, genetic changes. Humans are still evolving, and that is unlikely to change in the future. What do all humans have in common? Human nature: Six things […]
Is Boron 11 stable or unstable?
Is Boron 11 stable or unstable? Boron 11 Metal (Boron-11) is a stable (non-radioactive) isotope of Boron. It is both naturally occurring and a produced by fission. What is the half life of boron-10? 20.20 milliseconds Why is boron 9 not stable? Returning to our boron example, with only 4 neutrons, boron-9 is unstable, and […]

What happens if a hydrogen car catches fire?
What happens if a hydrogen car catches fire? The vehicles are designed with a thermal pressure relief device (TPRD) on the tank that would discharge if the car was engulfed in a fire. If a fuel leak were to occur, the hydrogen would disperse upward rapidly, and if the TPRD were activated, the tank would […]
How would sea turtles be affected by glacier melting?
How would sea turtles be affected by glacier melting? The Problem: Because sea turtles use both marine and terrestrial habitats during their life cycles, the affects of climate change are likely to have a devastating impact on these endangered species. With melting polar ice caps and rising sea levels, these beaches are beginning to disappear. […]

Do trees grow out of the air?
Do trees grow out of the air? But the truth is, trees are actually formed largely out of the air. (Yes, air!) Trees, and all photosynthesizing plants, use the energy of the sun to split atmospheric carbon dioxide into its constituents: oxygen and carbon. And carbon is the primary building block of the tree — […]
Can a population increase even though its growth rate is decreasing?
Can a population increase even though its growth rate is decreasing? Not only the population itself was growing, but also the doubling time was decreasing, which basically means that growth itself was growing. This rapid growth increase was mainly caused by a decreasing death rate (more rapidly than birth rate), and particularly an increase in […]
