Fire caused tuberculosis according to new archaeological theory. Evolution is very powerful. A change in climate leads to the survival of those who suit the new climate more adequately. A series of ice ages meant hairy people with narrow nasal passages (to warm the damaging cold air on it way into the lungs) passed on their genes. People living in central Africa remained in a warm climate, so they did not have to adapt. A new premise is that the adoption of fire by early humans caused the emergence of tuberculosis. Apparently, many people crouching around a fire set the ideal conditions for TB to take hold. Just a minute though. Didn't Africans also cook meat on fires and kept near to it for warmth on cold nights? They certainly did. No, this new theory does not hold up. It is assumed that TB is mainly a thing of cold climates.  More correctly, molecular archaeological evidence shows that TB began in Africa. Just how scientists reached the conclusion that humans ...

Why do plant seeds in Australia start germinating after a fire? It is because of Karrikin Insensitive2 (KAI2) a protein which has been present in plants for millions of years. KAI2 has been important for all plants for 400 million years. When the KAI2 protein was removed from a higher, more recent plant, Arabidopsis thaliana, its leaves malformed. Yet splicing the KAI2 back by taking it from the ancient Selaginella resulted in improved A. thaliana growth, but it could no longer detect the presence of smoke the normal function of KAI2. This finding shows the more general function of KAI2. It not only identifies karrikins in smoke, it is important for plant growth. "Sensing" is the main purpose of KAI2. Apparently it can be tuned to detect different things. This could help farmers control seed germination times. Wheat is notorious for germinating in the grain during heavy rain periods. Being able to spray a chemical that stops this would save millions of...

Many answers have been found for mysterious things in nature. As time moves on most of the reasons why things are have been answered. A few common scientific "happenings" still persist. If sodium is placed in water it explodes. The why has now been identified. A sodium-water explosion was filmed on high-speed cameras. The flash is caused by sodium hydroxide and hydrogen gases being release when water upsets the balance. Heat creates a point of ignition. The mystery is that released hydrogen gas should enclose the sodium thus stopping the explosive reaction. Like life itself the answer lies in electricity. All life, such as the nervous system, functions by the flow of electrical current. When the film of a sodium-water explosion was slowed down electrons (as metal spikes) were seen to jump from sodium into the water. The sodium becomes positive while the water also remains positive because of its mass. Like with magnetism two positive poles repel. ...

Australia is fighting against the spread of red fire ants. This pest has invaded other countries such as the US. Nothing seems to work to stop their malicious takeover. They give a nasty bite. It was thought to be a simple kind of ant but studies have shown it to be a complex creature. It has two distinct variants in its social structure. Normally colonies keep their distance. On the other hand, many colonies do form a supercolony where queens work together and breed in safety. Ants of the supercolony do kill queens of isolated colonies. The ants are different genetically. Queens of individual colonies are fatter. This is to feed the first larvae when they start the colony. Queens who work together never need the "boost" fat. The change of a single gene dramatically changes physicality and behavior. It is contentious as to whether there will be an evolutionary winner. We just do not know at this stage. It is hoped that chemicals producing violent behavior can ...
