The evidence is stacking up: Dietary supplements arent worth your money.The message from many doctors and scientists alike is simple: If you dont need them, dont bother taking them. But if people want to buy them, and they believe these pills, potions and powders make them healthier, whats the harm, right?
Perhaps its time for a rethink of this commonly held idea. A large new study has estimated that supplements send about 23,000 peopl Continue reading 23,000 People In The US End Up In ER Every Year Because Of Supplements
Charles Darwins theory of evolution offers an explanation for why biological organisms seem so well designed to live on our planet. This process is typically described as unintelligent based on random variations with no direction. But despite its success, some oppose this theory because they dont believe living things can evolve in increments. Something as complex as the eye of an animal, they argue, m Continue reading Intelligent Design Without A Creator? Why Evolution May Be Smarter Than We Thought
Researchers from the George Washington University have managed to switch consciousness on and off in an epileptic woman by stimulating a single region of the brain with electrical impulses. While this is a single case study, it provides an exciting insight into the neural mechanisms behind consciousness, a subject of great interest that is poorly understood despite decades of research. The <a href="http://www.newscientist.com/article/mg22329762.700-consciousness-onoff-switch-discovered-deep-in-brain.html?full=true# Continue reading Researchers May Have Discovered The Consciousness On/Off Switch
The red flowers and green foliage of the endangered Impatiens frithii grows on the surface of small trees and low branches in the mountains of western Cameroon. This bird-pollinated plant shares its main pollinator, the sunbird Cyanomitra oritis, with four other Impatiens species. But unlike others in the same genus—which have these downward curving sepal spikes that contain nectar—the “nectar spur” of Impatiens frithii curves slightly upward (pictured above).
In an example of evolution’s elegan Continue reading This Red Flower Curves to Conform to a Bird’s Bill

We often hear about the next big thing in stem cell therapy, though few of these promises eventuate or are backed up by evidence.
Well, we think were close to a genuine breakthrough in stem cell therapy, based on new research published today in Proceedings of the National Academy of Sciences.
We have developed a stem cell technique capable of regenerating any human tissue damaged by injury, disease or ageing.
The new technique, which reprograms bone and fat cells into <a h Continue reading Regenerating Body Parts: How We Can Transform Fat Cells Into Stem Cells To Repair Spinal Disc Injuries
