Pheromones are any chemical signal used to communicate between the members of a species. The existence of pheromones has been studied most thoroughly with respect to insects, but more complex species likely also possess pheromones.
The above diagram, by Peter Fluri, shows a female of the codling moth, Cydia pomonella, raising her abdomen and protruding her […]

Turbidity may sound like a complicated scientific term but in essence it is a simple definition concerned with the cloudiness of water. More specifically turbidity refers to the light that is able to pass through a water sample because of the sediment present in the liquid. In most cases it is measured using a meter […]

Scientists have found long-sought proof that people release potent chemical signals that can have profound effects on other people. Pheromones have been documented in many species, ranging from insects to elephants, as sex attractants, kinship identifiers or alarm signals.
In many species they are detected by a specialized organ inside the nose or mouth called […]

The exquisite specificity of insects chemical language is not surprising, considering that it is often the only means insects have for finding each other. Researchers have now broken the code for the pheromone communication of more than 1,600 insects. In so doing they have found that pheromones serve many more purposes than simply attracting mates. […]

Pheromones are chemicals emitted by living organisms to send messages to individuals of the same species. The idea that chemical communication takes place between individuals of the same species was advanced as early as the late 17th century the first evidence in support of this was obtained in the 19th century by the French priest […]

Almost all mammals do release these pheromones for attracting their partners and also in order to send alarm signals. The mammals have found out the best use of these pheromones than human beings and they are getting benefited in all senses. We can distinguish the pheromones in mammals into two categories depending on their functions.
1. […]

The word evolution has many meanings, but only one is testable, repeatable and observable. In other words, only one of the many definitions of the word evolution is a scientific fact.
This observable type of evolution is not Darwinian or Neo-Darwinian evolution. I will discuss that one form of evolution that is […]

Kids are all reeling from the excitement of the Olympic Games these last few weeks, but can they relate any of that to science? Absolutely!
Aspiring athletes, or students struggling with a scientific concept, may find that the perfect demonstration is sports. Many kids love sports, and sports are science. Every skill, movement, victory, and loss […]

A Dutch science teacher accidentally discovered what may be a new, astrological phenomenon. While Hanny van Artel was helping the Web site Galaxy Zoo identify galaxies, she spotted a greenish, gaseous object with a hole in it. Because it doesn’t have stars and thus can’t be a galaxy, astronomers think it is light from a […]

Heralded as a revolution by people who need glasses to read, laser eye surgery can eternally change your vision by reshaping the cornea. After a hinged flap is cut a portion of the cornea is revealed and exposed to laser pulses that vaporise the cornea and correct the shape permanently. This procedure can help […]
