Primates are thought to have evolved alongside other placental mammals after the K-T extinction event. They would continue to divide into numerous species over the next several million years. Around 30 million years ago monkeys had prehensile tails and eyes on the front of their head. Most are thought to have lived in Africa with some migrating to South America, possibly on a raft of vegetation. Five million years later primates would split into apes and monkeys, apes being notable for a ... more...

Transcranial magnetic stimulation is a non-invasive way of stimulating many different areas of the brain. Being addicted to drugs has a considerable toll on the individual. Now researchers are begining to use transcranial magnetic stimulation as a treatment for people who are addicted to various drugs. Depression and addiction often overlap on both the symptomatic and chemical level. States of both depression and addiction often share anhedonia the inability to experience pleasure. The reward... more...

The more we learn about human DNA the more apparent it becomes that Darwinists are blowing hot air with their claims that some apelike creature lurks in man's ancestral closet. Scientists who study such things say that human DNA molecules EACH contain enough hereditary data to fill a 500,000-page book. This data is translated by enzymes, all of which are encoded to protect against mutational defects. Both the genetic data and the enzymes that decode the information had to be there ... more...

Is society moving towards a future where people will be able to replace their biological neurons with computer chips or artificial neurons? Some researchers think that having implantable neural prostheses may be just around the corner. This currently science fiction scenario may actually not be that far off. There has been a continuing development of neural prostheses that are implantable in the brain. This type of implant will signal in a totally new era in bioengineering and also neuroscie... more...

Pheromones are natural chemical scents the body produces in order to attract others. They are well documented in the animal kingdom as the force that controls all social behavior, including mating. Scientists are now finding that human behavior is also heavily influenced by these invisible social magnets. A mystery chemical isolated from the sweat of young women seems to act as a romance booster for their older counterparts. When the researchers added the compound, Pheromone 10:13, to a p... more...

In Vitro Fertilisation (IVF) literally means fertilisation in glass. Instead of sperm penetrating the egg within the body (in vivo), fertilisation takes place in a sterile disposable dish in a laboratory (In vitro). Once the egg has been fertilised the resulting embryo is then transferred into the uterus with the hope of establishing a pregnancy. More than three million babies have been born using IVF and other assisted reproductive technologies (ART) since the worlds first IVF baby wa... more...

Scientists researching pheromones say that mammals think through their noses. Virtually all organisms, from yeast to insects to humans, produce volatile smelly pheromones that act as sexual magnets and send other messages such as dominance or fear. Pheromones are substances secreted by one animal that cause some behavioral response in a second animal. Pheromone is from the Greek words pherein, which means to bring or to transfer, and hormon, which means to excite. Most studied pheromones... more...

Darwinism can actually be scientifically refuted in SEVEN SECONDS FLAT or faster. I will time myself just before I finish writing this article and tell you how I did. Three facts are key to this demonstration. Fact No. One: The Code Barrier, best referred to as the DNA Code Barrier, is a scientific principle that one kind of plant or animal only has the genetic information in its gene pool to produce its own kind. Take a cow as a simple example. While there may exist t... more...

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 validated by real science later in this article. Darwinian or Neo-Darwinian-style evolution would be one kind of plant or animal changing into a different kind of plant ... more...

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 Henri Fabre, whose hobby was raising butterflies. Fabre demonstrated that antennae are the butterfly's organ of smell and that males are attracted to females for... more...

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 sex gland. She takes this calling posture for a short period in the early evening hours. Codling moth males casting through th... more...

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 vomeronasal organ, or VNO. There was ample evidence that human pheromones exist; babies show a clear preference for pieces of... more...

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. Releaser Pheromones Many mammals (e.g., dogs and cats) deposit pheromones in and/or around their "territory". As these vaporize, they sign... more...

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. As already discussed, Pheromones are powerful sex attractants. Till now hundreds of pheromones are known with which one sex (usually the fema... more...

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 kids experience is a science lesson waiting to be learned. Everything from the exchange of O2 and CO2 as Michael Phelps breathes between swimm... more...

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 no-longer-visible quasar; and the light, as it continues to travel through space, is echoing off a body of gas. For us who are science-challenged this is called a "... more...

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 although there are a variety of methods for obtaining a turbidity reading. Meters are normally best however as they are able to pick up on sediment particles that are so small that t... more...

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 myopic people suffering from sight-sightedness, and hyperopic sufferers with long-sightedness. However there is still the inevitable issue of age. Presbyopia is the condition wher... more...

Traumatic brain injury (TBI) is actually a major cause of disability and death in the world. It is a leading killer of people who are beneath the age of 45. The major causes of TBI include violence, falls, sports injuries and motor vehicle accidents. People can often prevent accidents when the proper safety precautions are taken. Traumatic brain injury can be devastating for those who have to undergo it. Those who have damage to their brain can have a range of negative side effects that can... more...

The Jurassic and Cretaceous periods are known as the time of the dinosaurs. During these two vast eras of time the world was dominated by these giant reptiles. Some of the sauropod herbivores are the largest animals to have ever walked the planet, and the Tyrannosaurus Rex is the largest ever land predator. The periods also saw the development of flowing plants, birds and mammals, all of which are still alive and thriving today. The start of the Jurassic period was signalled by the Triass... more...
