5 Mind blowing Random facts

Dolphins have been trained to be used in wars

A military marine mammal is a cetacean or pinniped that has been trained for military uses. Examples include bottlenose dolphins, seals, sea lions and belugas. The United States and Soviet militaries have trained and employed oceanic dolphins for various uses. Military dolphins have been trained to rescue lost naval swimmers or to swim head first into active deep sea mines.

Copper door knobs are self-disinfecting

Copper and brass doorknobs impedes bacterial growth by the process of oligodynamic effect, and it’s the result of metal ions in brass and copper having a toxic effect on molds, spores, viruses, and other living cells. Unvarnished brass doorknobs magically disinfect themselves in about eight hours. But if your knobs are made of another material like stainless steel or glass, beware. These non-self cleaning surfaces could be a hotbed of bacteria, with some microorganisms surviving for more than a month.

The human body literally glows

Emitting a visible light in extremely small quantities at levels that rise and fall with the day, scientists now reveal.

Past research has shown that the body emits visible light, 1,000 times less intense than the levels to which our naked eyes are sensitive. In fact, virtually all living creatures emit very weak light, which is thought to be a byproduct of biochemical reactions involving free radicals.

The world’s smallest reptile was first reported in 2021

The scientists found two of the tiny lizards, one male and one female, in northern Madagascar, and named the new species Brookesia nana, or nano-chameleon. According to their study, published January 28, 2021 in the journal Scientific Reports, the male nano-chameleon has a body that’s only half an inch (13.5 mm) long – about the size of a sunflower seed – making it the smallest of all the roughly 11,500 known species of reptiles on the planet.

The total weight of ants on earth once equaled the total weight of people

Entomologists have estimated that there are at least one million trillion insects and only one percent of that number is ants, according to the BBC. And if you took all those ants (about ten thousand trillion) and put them on one side of a giant scale, you could almost put all of the people in the world onto the other and balance things out. Unfortunately, as humans have become heavier, this probably wouldn’t hold up today—but it once did. Francis Ratnieks, professor of Apiculture at the University of Sussex, told the BBC this might have held true around 2,000 years ago.
