Alright readers…and by “readers” i mean, mostly me, but, i digress. My plan for this little corner of the internet…mostly i just surf around and and work sparingly throughout the work-week, so i’m thinking that i will just post the most interesting things i find throughout the day. Sounds pretty simple right? Really, not so much. Trying to write everyday, mixed with the fact that i’m bored spit less at my current job (but need to keep it because, you know, i need to pay rent) my inspiration is running a little low. However, my impediments shall not get me too down!
Red Bull Air Race is quickly becoming one of my favorite types of race to watch! These guys are in tiny planes, driving around a rather confined course going what looks like a billion MPH and they, mostly, do it flawlessly!
Now, what else do we have here?…Fucking science! The scientists have done it again folks…not only have they cloned something, but this time it’s an extinct creature. Oh, ya, you read that right…EXTINCT! As in does not exist on this planet any longer?! Ya, they fucking did it. Recently, scientists in Spain have cloned a Pyrenean ibex, a subspecies of Spanish ibex that went extinct in 2000. Sure, scientists have cloned endangered species before, but never one that had ceased to exist. “We are not especially disappointed for the death of the cloned newborn,” Folch explained in an email, because such deaths in cloning experiments are common.
But David Wildt, a senior scientist at the Smithsonian’s National Zoological Park in Washington, D.C., who did not participate in this study, warned that the successful cloning wouldn’t be the first step in creating a real-life Jurassic Park.
“The public should not leap to the conclusion that we are on the edge of cloning woolly mammoths or dinosaurs,” he said. “Even if such embryos could be constructed, there are no appropriate surrogate mothers for long-dead species.”
For 200 years, hunting had thinned the Pyrenean ibex population, and the last living bucardo died in 2000, hit by a falling branch.
Using frozen skin samples taken from this lone specimen in 1999, Folch and his colleagues made clone embryos by inserting the bucardo’s DNA into domestic goat eggs emptied of their original genetic material.
If the environment in which an embryo develops is not a close match, problems can occur during pregnancy. Of the 208 embryos the researchers implanted, only seven goats became pregnant, and just one bucardo made it to term.
The newborn bucardo died of respiratory failure immediately after birth. Dissection revealed the animal had lung abnormalities, although all its other organs looked normal.
Such abnormalities are common in cloning—while a clone’s DNA might be identical to its donors’, the act of shuffling DNA from one cell to another can lead to irregularities during development.
Reproductive biologist Bill Holt at the Zoological Society of London, who did not participate in this study, added that generating just one or a few animals via cloning “will not necessarily produce a viable population that would survive into the future.”
Even if all resulting offspring were healthy, he said, the fact that they only have a few genetic samples of the bucardo to work with would mean there would be no genetic diversity in the population, as in inbred groups.
“They would be very susceptible to disease or even climatic change and may not be able to survive for very long.”
Well folks, that’s it for today. I thought it was interesting, hope you did too.
Adios for now!
