While hundreds of millions of dollars are spent on masking and treating male pattern baldness, surprisingly little is known about its cause at the cellular level. A Journal of Clinical Investigation study has found that stem cells play an unexpected role in explaining what happens in bald scalps. Using cell samples from men undergoing hair transplants, researchers compared follicles from bald scalps and non-bald scalps and found that bald areas had the same number of stem cells as normal areas in the same person but noted that another, more mature cell type called a progenitor cell was markedly depleted in the follicles of bald scalps.
In an ideal energy future, man-made solar cells would mimic much of the functionality of efficient plant life. Currently solar cell technology is expensive and a maintenance headache but Purdue researchers are working a new type of solar cell that uses carbon nanotubes and DNA to come closer to plant life that can be durable enough for commercials use,
Their design exploits the unusual electrical properties of structures called single-wall carbon nanotubes, using them as "molecular wires in light harvesting cells," said Jong Hyun Choi, an assistant professor of mechanical engineering in the Birck Nanotechnology and Bindley Bioscience centers at Purdue's Discovery Park.
“Anyone who knows history, particularly the history of Europe, will, I think, recognize that the domination of education or of government by any one particular religious faith is never a happy arrangement for the people.”
“Will people ever be wise enough to refuse to follow bad leaders or to take away the freedom of other people?”
Everybody knows that the orbital momentum is "quantized" and its z-projection has integer eigenvalues in units of . Too few, however, know that it is, in fact, a quasi-particle angular momentum which is integer-valued, not the particle one!
Environmental groups are concerned they have lost the trust of the public regarding global warming so they have taken to new marketing approaches. They started the last decade with runaway public interest and goodwill and ended it with scandals and black marks on the credibility of the climate field.
On Tuesday, September 11th, 2012, I will make the attacks of 2001 a political issue. For almost 10 years, these attacks have been used by Republicans as a political issue, justifying everything from conspicuous consumption to the Two War Economy of stopping (inflaming) Global Terrorism.
2000 years from now, if future researchers find our Science 2.0 mug, what would it tell them?
Quite a bit, it turns out - at least regarding the social structure of the period in which we live. Coffee is big in society. But America is a young country compared to an ancient empire like Greece. Studying drinks in ancient Greece over a long period can help researchers piece together what the social structure may have been like beyond select older writings.
Western thought, from the sciences to the arts, have been based upon the rich mythology and history of the Ancient Greeks and Romans. One which seems to guide the subconscious thought of many of our political and financial leaders is the myth of Saturn (Chronos). Saturn, the Roman name for the Greek God Chronos, became the ruler of the deities after overthrowing his own father. However, Saturn, like most power hungry individuals, quickly aged and forgot the crimes perpetrated by his own father --
Does it take effort to tell the truth or are you naturally honest? In other words, are you truthful or a liar? A Harvard neuroimaging study showed that you're wired to be one or the other.
The study watched subjects' brains as they were presented with the opportunity to win money through lying. When honest people told the truth, their brains were at peace. When dishonest people lied, the control centers of their brains crackled to overwrite the truth with a lie. And here's the cool part: even when dishonest people happened to tell the truth, researchers watched their brains actively override the temptation to lie.
