As I’ve noted over and over and over again, adult stem cells are a win-win situation; they have amazing curative powers and have none of the ethical issues associated with embryonic ones. Well now, we hear of yet another source of stem cells that fit that category.

Scientists have made ordinary human skin cells take on the chameleon-like powers of embryonic stem cells, a startling breakthrough that might someday deliver the medical payoffs of embryo cloning without the controversy.

Laboratory teams on two continents report success in a pair of landmark papers released Tuesday. It’s a neck-and-neck finish to a race that made headlines five months ago, when scientists announced that the feat had been accomplished in mice.

The “direct reprogramming” technique avoids the swarm of ethical, political and practical obstacles that have stymied attempts to produce human stem cells by cloning embryos.

The fact that adult stem cells have been reprogrammed and used successfully isn’t mentioned in the article. You’d think the didn’t exist or were still very experimental by reading it. It’s unfortunate that these successes don’t get more play from the media, but then again, it’s a liberal media, and liberals have a fixation on embryonic experimentation, so that’s to be expected, claims of objectivity notwithstanding.

Still, it’s wonderful to hear the press acknowledging that there are indeed ethical considerations and that this new research could very well remove the need to wrestle with them. This kind of research is something we can all get behind, I believe, regardless of political and/or religious pursuasion.

There are still some issues to be worked out, notable the cancer risk, but this quote is incredibly promising.

“People didn’t know it would be this easy,” [James] Thomson [of the University of Wisconsin-Madison]said. “Thousands of labs in the United States can do this, basically tomorrow.”

Let’s hope so.

Given this statement…

“There was a tendency toward alarmism, and that fit perhaps a certain fundraising agenda.”

…what subject is it referring to? Global cooling in the 1970s? How about global warming of the 2000s? Don Sensing has a poll going about what people think this refers to. One of the seven is the right answer, but the statement applies just as easily to the other six. Alarmism spurs research grants, “carbon credits”, and all sort of cash transfers,so it’s no wonder that there’s a tendency to make things worse than they are.

In this case, the statement is referring to the AIDS epidemic. While there’s no doubt it is a scourge, the UN is revising it figures down; way down.

The United Nations’ top AIDS scientists plan to acknowledge this week that they have long overestimated both the size and the course of the epidemic, which they now believe has been slowing for nearly a decade, according to U.N. documents prepared for the announcement.

AIDS remains a devastating public health crisis in the most heavily affected areas of sub-Saharan Africa. But the far-reaching revisions amount to at least a partial acknowledgment of criticisms long leveled by outside researchers who disputed the U.N. portrayal of an ever-expanding global epidemic.

The latest estimates, due to be released publicly Tuesday, put the number of annual new HIV infections at 2.5 million, a cut of more than 40 percent from last year’s estimate, documents show. The worldwide total of people infected with HIV — estimated a year ago at nearly 40 million and rising — now will be reported as 33 million.

Having millions fewer people with a lethal contagious disease is good news. Some researchers, however, contend that persistent overestimates in the widely quoted U.N. reports have long skewed funding decisions and obscured potential lessons about how to slow the spread of HIV. Critics have also said that U.N. officials overstated the extent of the epidemic to help gather political and financial support for combating AIDS.

“There was a tendency toward alarmism, and that fit perhaps a certain fundraising agenda,” said Helen Epstein, author of “The Invisible Cure: Africa, the West, and the Fight Against AIDS.” “I hope these new numbers will help refocus the response in a more pragmatic way.”

But…but…I thought the scientific community didn’t work this way. If the science is settled, it’s settled, not bought. Right?

Right?

One of the podcasts I listen to is Heading Right Radio with Ed Morrissey of “Captain’s Quarters”. He gets some great interviews, and last week (I’m behind in my podcast listening) he got Dinesh D’Souza and they talked about D’Souza’s book “What’s So Great About Christianity”. Fresh from his debate at King’s College with Christopher Hitchens, D’Souza covers a number of interesting topics from his book, including the truth about the Gallileo’s persecution, the limits of reason, why the recent increase in atheist apologetics, the supposed “war” between science and religion, thank-you letters to Portugese inquisitors, and other light topics. >grin<

Adult stem cells, that is.

University of Manchester researchers have transformed fat tissue stem cells into nerve cells — and now plan to develop an artificial nerve that will bring damaged limbs and organs back to life.

In a study published in October’s Experimental Neurology, Dr Paul Kingham and his team at the UK Centre for Tissue Regeneration (UKCTR) isolated the stem cells from the fat tissue of adult animals and differentiated them into nerve cells to be used for repair and regeneration of injured nerves. They are now about to start a trial extracting stem cells from fat tissue of volunteer adult patients, in order to compare in the laboratory human and animal stem cells.

Research continues in both adult and embryonic stem cells, but the big news from adult stem cells just keep coming and coming. What’s interesting is that this breakthrough could lead to the very result that the late Christopher Reeve and other supporters was suggesting could happen only if the feds paid for embryonic stem cell research. But here we have stem cells that could potentially repair nerves with nary an ethical or moral issue.

So why the exaggerated imperative over embryonic stem cells? One has to wonder.
