Thanks to advances in biotechnology and genetic engineering, we are finding ever more complex ways of converting nature into living protein factories that serve our needs. Engineered bacterial cells can churn out medically useful proteins such as insulin, the blood-clotting agent thrombin, and a host of other human enzymes and hormones. Plants, yeast and even other mammals can be given the genes needed to produce valuable proteins that they don’t make naturally. Most famously, even notoriously, genetically modified goats can secrete spider silk in their milk, which can be extracted and used to make tough fibres. But in many ways this is taking a sledgehammer to a nut. If all you want is a particular protein – whose chemical structure in encoded within a gene in DNA – then even a bacterium is an awfully complicated bit of machinery to make it.

I have been involved in alternative energy research for the last 4 plus years. My research into Nikola Tesla, Victor Schauberger and John Keely taught me that energy and the search for it in the universe is highly interrelated with energy of the body and the search for greater health. One hundred years ago there were more electric cars on the road than gasoline powered ones.
One of the four sons of Horus was Hapi. The four sons of Horus were a group of four gods in Egyptian religion , who were essentially the personifications of the four canopic jars , which accompanied mummified bodies. [ 1 ] Since the heart was thought to embody the soul , it was left inside the body. [ 2 ] The brain was thought only to be the origin of mucus , so it was reduced to liquid, removed with metal hooks, and discarded. [ 3 ] This left the stomach (and small intestines), liver, large intestines, and lungs, which were removed, embalmed and stored, each organ in its own jar. There were times when embalmers deviated from this scheme: during the 21st Dynasty they embalmed and wrapped the viscera and returned them to the body, while the Canopic jars remained empty symbols.

A cutaneous condition is any medical condition that affects the integumentary system — the organ system that encloses the body and includes skin , hair , nails , and related muscle and glands . [ 1 ] The major function of this system is as a barrier against the external environment. [ 2 ]

Over its first few decades, the human cerebral cortex — the brain’s wrinkled outer tissue — evolves in ways that parallel its evolution since we last shared a common ancestor with macaque monkeys.

The finding suggests the ability to produce sperm arose just once, 600 million years ago, and has been conserved through all subsequent animal evolution. <img class="alignright size-medium wp-image-24069" title="Various sperm" src="http://www.wired.com/images_blogs/wiredscience/2010/07/Picture-2-236x300.png" alt="" width="236" height="300" />
Chicago -- Children with even relatively mild concussions can have persistent attention and memory problems a year after their injuries, according to a study that helps identify which youths may be most at risk for lingering symptoms. In most children with these injuries, symptoms resolve within a few months, but the study suggests that problems may linger for up to 20 percent of them, said study author Keith Owen Yeates , a neuropsychologist at Ohio State University's Center for Biobehaviorial Health . Problems such as forgetfulness were more likely to linger than fatigue, dizziness and other physical complaints, the study found.
