Warm Blooded Plants

Few people realize that some plants can actually thermo-regulate themselves. They behave as if they were mammals by altering heat production to keep their temperatures surprisingly constant. Plants with the ability to warm themselves include philodendron, Jack in the Pulpit, Skunk Cabbage and many members of the Lily family. Experiments on some species of philodendron…

Battling microbes is becoming increasingly important, since bacteria that are immune to antibiotics are now showing up in some food products. Since cutting boards and kitchen work surfaces are common bacterial breeding grounds, it’s important to carefully clean these. Wouldn’t it be nice to always count on having a microbe-free work surface? Well, this is…

Life In Your Microwave Oven

Microwaves are super high frequency electro magnetic waves often used in communication systems. Most of us meet microwaves when we cook in a microwave oven.  Microwave ovens generate super high frequency waves and scatter them throughout the oven.  The frequency of microwaves is just right to give energy to water molecules.  Microwaves cause them to…

Explosives

An important application of chemical energy is the use of explosives. Any substance that undergoes a very rapid chemical reaction which has a strong heat-liberating quality, or that produces a large volume of gases from a solid or a liquid, is potentially an explosive. The destructive power of an explosion is due to the shock…

Snow provides more than winter fun.  It supplies a measured supply of water to underground water reserves as it slowly melts and percolates down to the water table.  In contrast, rain water is often carried away quickly as surface runoff along with an accompanying soil erosion. Falling snow also purifies the air.  Every snow flake…

This time, Dr. Humphreys and Ron Hughes discuss the improbability of Chemical Evolution, which is a major problem for the theory of Biological Evolution. Ron Hughes:  People think of Biological Evolution, starting with single celled aquatic creatures and ending with man, but what most people don’t think is Chemical Evolution.  I mean, all the building…
