Embryo-free Embryonic Stem-Cells

Simple switch turns cells embryonic. "Researchers have finally hit the jackpot: Embryo-free embryonic stem-cells!"
Is this the same trick that could cause cancer in humans?
But these so-called “iPS” cells still showed significant differences from embryonic stem cells. The three new papers report on creating iPS cells that proved virtually identical to stem cells in a variety of lab tests.posted by SansPoint at 12:11 PM on June 7, 2007
The technique used in the mouse studies could promote cancer in any patients getting therapy based on iPS cells, so researchers emphasized that a new approach that avoids that hazard would have to be developed.
Gearhart called that a major issue to be resolved. In addition, he said, scientists still must show that these cells can give rise to many cell types in the lab, as embryonic stem cells can.
Shit! We'd better cook up a new way to prevent the march of scientific progress, now that stem cells don't necessitate murder anymore.

Yeah, this is good. But it's really sad that scientific progress has to be hampered by tiptoeing around the anti-science fundamentalists. This wouldn't be as big of a deal if we didn't have to deal with them.

All potential embryonic stem cells must immediately be turned into actual embryonic stem cells so they can be protected!!!

YAY! We be not killing babies no more!
Now maybe all those rich right wing Christians nut bags will stop hurting the science and see how they really WILL be able to live forever.
Oh. Wait a minute.
Snark aside this is very cool.
Of course so far the benefits only seem to apply to mice.
Holy shit. IMMORTAL MICE!

From the second link in explanation why this is better than other methods of harvesting stem cells:
This will lead to animal-human hybrids? The reason for considering this method was based on the greater availability of animal eggs for use in therapeutic cloning, which would no longer be necessary.
What? Did people really suggest that using stem cells was going to create hybrids? Perhaps they were watching too much Dark Angel and thought the whole transgenic warrior thing was a little too scary.
Seriously, if animal-human hybrids was ever brought up then we have officially taken this FUD thing to a whole new level.
Otherwise this is good news. Yay for science. (Assuming they can make it work in humans.)

Maybe you need to watch less Dark Angel and read more about science. They're referring to chimeras here, and there are plenty of non-religious ethical concerns with these "hybrids."

I am immediately skeptical of scientific reporting where researchers "hit jackpots". There's no guarantee those genes work the same way in humans, or if there are massively bad side effects.

Well, there are plenty of reasons outside of political/religious considerations to pursue new methods for obtaining embryonic-stem-cell-like cells. For instance, in most therapeutic applications, you would want to have stem cells that genetically match the patient. The traditional approach (and an approach that hasn't yet successfully been performed in humans) is to transfer the nucleus of a cell from the patient to a "donor" egg cell. This is a difficult process, complicated by the fact that donated human egg cells are not very easy to come by (Hwang ran into a raft of ethical problems on top of his fraud seeking to obtain egg cells). This technique avoids these complications.
Plus, there's a value to fundamental science in doing this work. The researchers are learning important things about the genes that control the fates of cells during development and the "potency" of stem cells (the ability of these cells to become other types of cells). This fundamental understanding will be essential to the development of stem-cell-based therapies, particularly in guaranteeing that transplanted stem cells behave as we want them to instead of turning into tumors.
TungstenChef writes "They're referring to chimeras here, and there are plenty of non-religious ethical concerns with these 'hybrids.'"
quin isn't referring to chimeras (individuals containing two genetically distinct cell lines), but to hybrid cells created by transplanting human nuclei into animal cells. These cells would contain human nuclear genetic material but animal mitochondrial genetic material. Weird.
Blazecock Pileon writes "There's no guarantee those genes work the same way in humans, or if there are massively bad side effects."
When it comes to cutting-edge research, guarantees are few and far between.

They know Dubya will thow a veto at this.
The democrats are (wisely) pushing bills they know Bush will veto. It's a machiavellian strategy designed to force the republicans to vote again and again with their albatross of a sub-30% approval ratings president. These votes will like daggers in the eyes of republicans seeking (re)election in 08. It's awesome.

Well, the Democrats are at least (in many cases) fulfilling campaign promises by passing the legislation that their constituents want. That Bush asses himself and his party by constantly stamping out bills that have a load of popular approval is a convenient byproduct of this.
What is the alternative? To not waste any time or money fulfilling campaign promises that they knew would just get vetoed, and then in 2008 have to convince the voters that they really, really would have passed things if there had been a prayer of them getting past Bush, honest?

Ok The World Famous, time for a hypothetical.
You are standing next to a railway switch. Barreling down the track is a packed commuter train. With the switch as it is now, the train will plunge into a flooding river that has washed away the railway bridge, hundreds will die. Alternately, you can throw the switch, which will divert the train straight into a station wagon filled with nuns and puppies, which has become high centered on the rails in an attempt to flee the rising waters.
What do you do? If the ends never justify the means, I think it's pretty clear that you are obligated not to act. After all, you would have caused the unjustifiable deaths of several nuns, and an indeterminate number of puppies.

No, this is still a big deal. Cloning to produce embryonic stem cells is about 1% successful. If we need cells from you to fix a problem, we'd need hundreds of eggs and surrogates to get your clone. If they can figure out how to control the cells, with this method all they need is a skin sample and a Petri dish.
In terms of animal research, refinement of technique to reduce animal usage is mandated by law. This is one hell of an exciting refinement that will certainly result in a major reduction of animal usage while still granting us some spectacular potential benefits. Biopsy --> Cells in a dish --> potential for stem cell therapy? Everyone wins.

Well, possibly. However, this breakthough, and also that of Kevin Eggan's group, has been published just in time for a big international stem-cell conference in Oz.
Like "caution Live frogs", I would add that creation of EScells by SCNT is very, very inefficient and new routes to such cell-lines are of great interest both scientifically and also from the standpoint of possible future medical treatments.
