The Body Electric June 7th, 2010
Are people electric? The idea that human beings have electrical current running through their bodies most likely is not something you think about very often. However, every living function, whether it is conscious or unconscious, physical or mental, is powered by low levels of electrical current.... [Read More] |  |

Temperature-sensing protein linked to skin cancer, hirsutism April 27th, 2010
New findings about a temperature sensor in the skin could lead to novel approaches to controlling excess hair growth and treating skin cancers.
The common denominator that unites these seemingly unrelated processes is a versatile protein called TRPV3. The new research shows that in addition to... [Read More] |  |

Scientists create artificial human skin with biomechanical properties using tissue engineering April 27th, 2010
Scientists from the University of Granada, Spain, have generated artificial human skin by tissular engineering basing on agarose-fibrin biomaterial. The artificial skin was grafted onto mice, and optimal development, maturation and functionality results were obtained. This pioneering finding will... [Read More] |  |

Programmable Tattoos April 3rd, 2010
Squid and octopi do it. They change their skins to blend into the color and textural patterns of their environment. Specialized skin cells, called chromatophores, allow them to change color, reflection or even refraction. This also allows them to communicate with other octopi for mating or to warn...

Mirror Neurons March 15th, 2009
The adage “Do as I say, not as I do” is as ineffective today as ever, and now we may be able to explain why. Research investigating specific brain structures called mirror neurons may provide insight into how we learn behaviors and skills.
What are Mirror Neurons?
Mirror... [Read More] |  |

Electroreception December 23rd, 2008
Like humans, all living creatures are electric beings and in many cases use their electroreception to guide them directionally and instinctually—an electric sense. For example, the electroreception of the great white shark allows up to 8 Hz of frequency to be detected from opposite sides of the... [Read More] |  |
