Chinese scientists announce stem-cell research breakthrough

2 Comments

Previously, I blogged about how scientists had discovered a way to prevent ethical adult stem cells from being infected with cancerous mutations. I’ve also written about some of the proven cures that have been developed with adult stem cells and compared it with the number of cures developed by unethical embryonic stem-cell research, i.e. – NONE.

But now we learn about a new source of functional stem cells: PIGS! That’s right, PIGS!

Check out this story from the BBC.

Excerpt:

Chinese scientists have given cells from adult pigs the ability to turn into any tissue in the body, just like embryonic stem cells.

They hope the breakthrough could aid research into human disease, and the breeding of animals for organ transplants for humans.

The study appears online in the Journal of Molecular Cell Biology.

…Tests showed that the reprogrammed cells were capable of becoming any of the cell types that make up the three layers in a developing embryo.

Now you say, “Wintery! What good are pig stem cells for human beings?” So I’ll tell you.

Dr Xiao said pigs were a potentially ideal source of organs for transplant, as their organs were similar in function and size to those found in humans.

He said reprogrammed stem cells could potentially be used to make a pig organ compatible to the human immune system, minimising the risk of rejection.

The cells could also be used to mimic human disease in pigs, allowing scientists to test new therapies without requiring human volunteers.

There’s more in the story, it’s worth a look!

BONUS (depressing, though)

My elusive friend Richard e-mails me this article from the CBC, which talks about Quebec’s plan to pay for screenings for pregnant women to see if their child has Down’s syndrome. The article states that “statistics in other countries show that 90 per cent of women end their pregnancy after a positive test.” Quebec is the most secular and left-wing province in Canada.

What is it about the weak that causes leftists to want to kill them? Is it because they desire happiness for themselves above all and do not believe that humans have certain inalienable rights guaranteed by God? Is it because they believe that there is no value in suffering a little in order to take care of others has no value in a mindless, accidental universe where the only purpose is to have happy feelings until you die?

Does the new Ida fossil prove evolution?

2 Comments

Well, if it does, doesn’t that mean that evolution wasn’t proved before?

But I digress. Whenever you have questions about evolution and culture, there is only one blog that you really need to read, and that’s Denyse O’Leary’s Post-Darwinist. She has written no less than THREE stories on the Ida fossil, so let’s take a look at see what she’s found.

First, on May 19th, she noted that the lemur-like fossil contradicted the current best naturalistic theory of human origins.

[The] fossil doesn’t “explain” human evolution; it complicates the picture. The theory that was gaining ground was that humans were descended from tarsier-like creatures, but this fossil, touted as a primate ancestor, is a lemur-like creature.

Second, on May 21st, she added:

This recent Messil Pit find bolsters the case of the lemur supporters against the previously dominant tarsier supporters.

That only creates more confusion about origins, it seems to me, rather than resolving anything.

Where you have opposing histories, evidence that strengthens one history must weaken the other.

It does not necessarily add up to a gain in information.

What if the tarsier advocates find a fossil that bolsters their case in, say, 2012?

And who’s to say that won’t happen – as it has happened already?

Everything gets so complicated, once you look past the “missing link” sound-bites. But many people looking for validation for their atheist lifestyle will never bother – so long as the cultural authorities can offer them some Piltdown Man or Archaeoraptor or Haeckel’s embryos or Peppered Moths, etc., to justify their atheistic faith.

Denyse also points to a round-up of links from Access Research Network, as well as a New Scientist story that is skeptical of Ida’s status as *the* missing link.

Third, on May 25th, she linked to this story from the UK Times Online:

… in the research paper detailing the discovery, the scientists had painted a rather different picture. Ida, they said, “could represent a stem group from which later anthropoid primates (including humans) evolved but we are not advocating this here”.

And more:

Robert Foley, professor of human evolution at Cambridge University, believes many people misunderstand the huge timescales involved in assessing fossils.

“This animal lived around 47m years ago but human-like creatures only appeared in the last 2m years,” he said. “That’s a gap of around 45m years with many other species lying between us and that era. Any one of them could be called a missing link. Really, the term is meaningless.”

Now I know what my many atheist readers are saying: “we’re only skeptical of your beliefs! Not our beliefs!”. Well, I’m sorry, true believers, to throw cold water on you.

HUGE natural gas discovery in Louisiana! And Texas, Arkansas and Pennsylvania!

GREAT NEWS! Oh, I know that I usually say some depressing things on this blog… but I’m going to make up for all that right now by bringing out the Bobby and Supriya Jindal picture to illustrate this exciting story.

Here’s the story from the Wall Street Journal, courtesy of commenter ECM. The title is “U.S. Gas Fields Go From Bust to Boom”.

Excerpt:

A massive natural-gas discovery here in northern Louisiana heralds a big shift in the nation’s energy landscape. After an era of declining production, the U.S. is now swimming in natural gas.

Even conservative estimates suggest the Louisiana discovery — known as the Haynesville Shale, for the dense rock formation that contains the gas — could hold some 200 trillion cubic feet of natural gas. That’s the equivalent of 33 billion barrels of oil, or 18 years’ worth of current U.S. oil production. Some industry executives think the field could be several times that size.

“There’s no dry hole here,” says Joan Dunlap, vice president of Petrohawk Energy Corp., standing beside a drilling rig near a former Shreveport amusement park.

Huge new fields also have been found in Texas, Arkansas and Pennsylvania. One industry-backed study estimates the U.S. has more than 2,200 trillion cubic feet of gas waiting to be pumped, enough to satisfy nearly 100 years of current U.S. natural-gas demand.

The discoveries have spurred energy experts and policy makers to start looking to natural gas in their pursuit of a wide range of goals: easing the impact of energy-price spikes, reducing dependence on foreign oil, lowering “greenhouse gas” emissions and speeding the transition to renewable fuels.

…The natural-gas discoveries come as oil has become harder to find and more expensive to produce. The U.S. is increasingly reliant on supplies imported from the Middle East and other politically unstable regions. In contrast, 98% of the natural gas consumed in the U.S. is produced in North America.

Coal remains plentiful in the U.S., but is likely to face new restrictions. To produce the same amount of energy, burning gas emits about half as much carbon dioxide as burning coal.
