Making Embryonic Stem Cells From Human Skin Cells
By not using actual embryos, scientists at two Oregon-based institutions sidestepped one of the largest issues surrounding stem cell technology. The breakthrough follows similar success with monkey skin cells in 2007.
What's the Latest Development?
A paper appearing in the online version of Cell this week describes the successful reprogramming of human skin cells into embryonic stem cells. Scientists from the Oregon Health & Science University and the Oregon National Primate Research Center figured out that the fragility of human egg cells -- into which a nucleus from another human cell, in this case skin, is transferred and begins to produce stem cells -- required a different approach. By chemically maintaining an important stage of the cell division process throughout the transfer, the team was able to get the stem cells to develop. They achieved similar success with monkey cells in 2007.
What's the Big Idea?
Stem cell therapies have long been seen as a holy grail treatment for many common diseases including multiple sclerosis and Parkinson's disease, yet many have questioned the ethics of using developing human embryos for this purpose. Although the method discovered by the Oregon team can be considered a type of cloning, team leader Shoukhrat Mitalipov says, "Our research is directed toward generating stem cells for use in future treatments to combat disease...[We do not] believe our findings might be used by others to advance the possibility of human reproductive cloning."

Meteorologists propose a stunning new explanation for the mysterious events in the Bermuda Triangle.
One of life's great mysteries, the Bermuda Triangle might have finally found an explanation. This strange region, that lies in the North Atlantic Ocean between Bermuda, Miami and San Juan, Puerto Rico, has been the presumed cause of dozens and dozens of mind-boggling disappearances of ships and planes.
Nazi supporters held huge rallies and summer camps for kids throughout the United States in the 1930s.
- During the 1930s, thousands of Americans sympathized with the Nazis, holding huge rallies.
- The rallies were organized by the American German Bund, which wanted to spread Nazi ideology.
- Nazi supporters also organized summer camps for kids to teach them their values.

- A new study finds drinking large amounts of coffee and tea lowers the risk of death in some adults by nearly two thirds.
- This is the first study to suggest the known benefits of these drinks are additive.
- The findings are great, but only directly apply to certain people.
