Flavanols in cocoa may enhance brain blood flow, improve cognitive health: "A new study by boffins at the Brigham and Women's Hospital and Harvard Medical School has found that cocoa flavanols may enhance brain blood flow and improve cognitive health"
At last, an excuse to eat chocolate. The article reports the finding without description of what is going on.

BREITBART.COM - Science Finding Ways to Regrow Fingers
BREITBART.COM - Science Finding Ways to Regrow Fingers:" ACell Inc., that makes an extract of pig bladder for promoting healing and tissue regeneration.
It helps horses regrow ligaments, for example, and the federal government has given clearance to market it for use in people. Similar formulations have been used in many people to do things like treat ulcers and other wounds and help make cartilage.
The summer before Lee Spievack's accident, Dr. Alan Spievack had used it on a neighbor who'd cut his fingertip off on a tablesaw. The man's fingertip grew back over four to six weeks, Alan Spievack said.
Lee Spievack took his brother's advice to forget about a skin graft and try the pig powder.
Soon a shipment of the stuff arrived and Lee Spievack started applying it every two days. Within four weeks his finger had regained its original length, he says, and in four months 'it looked like my normal finger.'

This is how science used to be done. 'bubble,bubble toil and trouble' It is interesting and needs to be explained using conventional science.

BBC NEWS | Health | Mice cloned from skin stem cells
BBC NEWS Health Mice cloned from skin stem cells: "Mice cloned from skin stem cells
Many cloned mice survived into adulthood
US researchers have cloned healthy mice from skin cells for the first time.
Despite notorious difficulties in producing animals through cloning, nine of 19 mice who were born survived into adulthood.
The scientists replaced the nucleus from an unfertilised egg with the nucleus from an adult skin stem cell. Mice cloned from skin stem cells

This method can provide embryos from a male subject. Embryonic stem cells can be derived from that embryo.

Seeing Molecules
http://sciencematters.berkeley.edu/archives/volume4/issue25/story3.php
Yang is developing a better way to study biomolecules in motion. "What we hope is to visualize chemistry one molecule at a time."
For this feat, Yang uses a technique called single-molecule microscopy. The method employs probes that fluoresce red or blue when excited by a photon of light. The blue one can acquire photons from an external light source, while the red one only accepts photons from its blue counterpart. For his experiments, Yang affixes one blue and one red probe to opposite ends of a study enzyme. When the enzyme is relaxed, and both probes are far apart, the assembly glows blue. When the
enzyme closes, the blue probe can pass along its photon, and the assembly glows red.
Ultimately, Yang's work could result in advances in disease research, drug design, turbulence, materials analysis, and even our grasp of basic biochemical reactions. Says Yang, "I hope that in doing these experiments, we will get the chance to know how nature makes these things happen, and take that understanding to improve our quality of life."
Medical transformation is founded on advances like this are fundamental processes can first be observed and confirmed.

First Lady - Truth on Heart Disease by Carey Roberts
First Lady - Truth on Heart Disease by Carey Roberts: "Why the sex difference? Because men more often have high blood pressure and smoke cigarettes. And experts believe men are subtly discouraged from seeking help when heart disease lurks in its early stages. "
Because men have high blood pressure? Because men smoke cigarettes? Somebody is smoking something. I think it is the writer of this article. Men have been kicking the smoking habit recently. Unfortunatly, women have been taking a smoke more frequently.
Because men have high blood pressure? Because men smoke cigarettes? Somebody is smoking something. I think it is the writer of this article. Men have been kicking the smoking habit recently. Unfortunatly, women have been taking a smoke more frequently.
The whole course of heart disease is different in men. Men tend to get clogged arteries in specific locations. Women get them throughout the arteries-completely. Hormones protect women below a certain age. Men do not have that protection. Additionally, men tend to do the heavy lifting. That is always a good time to test your ability to have a heart attack. Extra strain on the fibrous cap causes it to break and you have a heart attack. Carey Roberts needs to explain the errors of her ways.

Nerve Regeneration with a Twist
Wang, an assistant professor in the Wallace H. Coulter Department of Biomedical Engineering at Georgia Tech and Emory University, discovered that he could integrate dopamine, a type of neurotransmitter, into a polymer to stimulate nerve tissues to send out new connections. The discovery is the first step toward the eventual goal of implanting the new polymer into patients suffering from neurological disorders to help repair damaged nerves. The findings were published online the week of Oct. 30 in the Proceedings of the National Academy of Sciences (PNAS).

April 7, 2006— New eyeglasses that shift focus from distant to near objects could soon replace bifocals and correct other vision problems.
The so-called switchable electro-optic diffractive lenses were reported in the Proceedings of the National Academy of Sciences by researchers at the University of Arizona in Tucson andf the Georgia Institute of Technology.
This is another example of things I have thought about that are invented almost as quick as you think of them. Could these self focusing glasses take on other roles. Binoculars for example or magnifying glasses. These would be neat if they work.

Australian Experts seek Samantic Nuclear Cell Transfer Rights
Forum chairman and Victoria's Chief Scientist Sir Gustav Nossal wrote: "We affirm that embryonic and adult stem cell research should be pursued as complementary avenues of investigation that hold promise for a better understanding of developmental processes, disease, assisted reproductive technology and stem cell-based human therapeutics. "There have been great advances in embryonic stem cell research in recent years, and sufficient evidence exists in animal models to justify the adoption of recommendations from the Lockhart review to enable the pursuit of this work in human systems."

This is another appeal to dishonest logic dealing with embryonic stem cells. This approach holds that somehow everyone has missed the fact that adult stem cells are an exact replacement for embryonic stem cells and that any money that is spent on ESC is taken away from adult stem cell work. Of course, stem cell research is not a zero sum game. Adult stem cell research is needed as is ESC. All claims to the contrary are at best ill informed and at worst dishonest.

Human Embryonic Stem Cells without Mouse Feeder Cells
A scientist in India is one of the first scientists to have created embryonic stem cell lines without using mouse feeder cells to grow them. Indira Hinduja, who created the country's first test-tube baby, used human feeder cells to grow the embryonic stem cell lines so they would not be contaminated.

Growing a finger to replace one lost due to war injury. This sounds like science fiction but that is the goal during the next five years for a group called 'Pittsburgh Tissue Engineering Initiative'.
"Dr. Anthony Atala, director of the Wake Forest center, said it's already possible to create some simple body tissues. He said the key will be learning how to combine those smaller tissues to form something larger, such as a finger or an ear."
These procedures will surely shock the public since so little is know about them generally and the possibility is not thought to be possible.
