Title: Scientists have grown the embryos of a extinct species
Post by: nickiknack on March 16, 2013, 04:52:51 pm

At yesterday's TEDxDeExtinction event, University of New South Wales paleontologist Michael Archer announced the advance by the so-called Lazarus project. The bizarre gastric-brooding frog, the female of which incubated the prejuvenile stages of its offspring in its stomach, disappeared from the wild in 1979 and went extinct a few years later. However, Adelaide frog researcher Mike Tyler froze specimens of the frog prior to its extinction, leaving the door open for the species' possible resurrection.

Scientists extracted DNA from a frozen frog specimen, and employed somatic-cell nuclear transfer, the same process used to clone still-living animals. The team took eggs from the distantly related great barred frog, deactivated that frog's DNA with UV light, and inserted the gastric-brooding frog's DNA into the eggs. The cells inside the eggs began dividing, becoming blastulas. The embryos died after a few days, long before developing into tadpoles, but DNA tests confirmed that they were gastric-brooding frog embryos, and Archer says they have high hopes for seeing this frog up and hopping soon.

This is so cool.

Perhaps one day we can shoot for the Dodo...

Yes, Indikins, assuming certain issues with the technology are solved.  I suspect they will.

They're still a ways away from bringing back a species.  These embryos all died after a few days.  But it's a tremendous step forward, and they believe that the problems they've encountered are solvable.  And if anyone would know, it's them.

Allosaurus is actually my favorite animal, but as no dinosaur DNA has ever been found (or is likely to be found) I doubt there's any way to bring one back to life.

I think that as science improves, the viability of literally returning extinct species to life will become a reality. After managing to get something extinct to actually survive to adulthood, the next step is figuring out how to "customize" DNA to basically build our own  genetic material. That opens the door to unbelievable possibilities regarding cloning.

And actually, both of those parts are steadily progressing. The hard part is sequencing the genome of what you want; DNA doesn't last more than a million years usually, and you need a parent species anyways (at least until we're able to totally customize biology and build our own eggs to fertilize). Dodo? Pretty easy if we can find DNA. Dinosaurs? Not so much.

Sure. A bunch of carnivorous and highly dangerous monsters are built without government approval, but remain strictly under control and restricted to a single pair of islands until the protagonists break them out of captivity and intentionally sabotage the efforts of the only competent people around in the name of "wildlife preservation" until a T-Rex is unleashed on San Francisco.

I remember reading about that. It was actually a misquote of a scientist who was interviewed for a German magazine (Der Spiegel I think) and it was actually him talking about a hypothetical situation.

You know how birds are said to be some of the closest descendants to dinosaurs? Well I remember seeing a program on the Science Channel or something that explored this. One thing they did was take a chicken egg and they changed the DNA so that certain "switches" where either flipped on or off so as to achieve the result they wanted. As the embryo grew it was observed to be behaving as predicted in that it grew a longer tail, teeth like structures on the beak, and other traits that made it look very dinosaur like. They ended up destroying it before it was close to hatching. I've always wondered what would happen if such a creature was allowed to grow until it hatched... We need to use a ostrich egg next time though.

This is actually an interesting proposition: what will the meat and animal products industry look like if science is able to freely and cheaply clone all sorts of species, including extinct ones? Will dodo cutlet become the new filet mignon if they can be grown?

This goes hand-in-hand with the thread on "printing body parts" and "printing bacon", where lab-grown cells are rapidly combined into tissue. Proper scientific endeavors will be a great boon for agriculture, as there will be less restrictions on land usage and fewer ethical problems with lab-grown meat.

"Cloning dinosaurs" will probably turn out a lot like the Jurassic Park novel: Wu notes to Hammond that they're not REALLY cloning dinosaurs, but rather making new monsters that have never existed in nature that just seem like dinosaurs. While actually bringing a dinosaur back to life is extremely difficult, creating a custom species that greatly resembles dinosaurs is much easier.

If Wu continues with chicken embryo gene manipulation, he could sorta "resurrect" an  Archaeopteryx analog

I wanna see a giant sloth, though (use a grizzly bear to gestate it maybe?)

That's actually James Bond himself on a rocket platform, replacing the classic jet pack from Thunderball, a far superior film also starring Sean Connery as Bond and made with the regular EON cast and essentially the same plot. For people who aren't Bond fans, Never Say Never Again was basically a remake of the earlier film by a different company with the same actor as Bond, but in the 1980s. The only things of note were the black Felix Leiter before the Daniel Craig films did it and the first film appearance of the Beretta 93R machine pistol.

I know the movie.

It was a competing film and they had to fight with EON for a while to get it made. The movie has Bond using a Walther P5, probably because the use of PPK would have been too close to the "official" Bond movies or something.

But seriously, look at that guy: Blue skin, lightsaber, no pants. What the heck?

The lightsaber is I think a strap from his equipment or the rocket platform, and he's wearing one of those ridiculous decades-old wetsuits that has short shorts instead of full leg coverings.

The blue skin is just a shitty artist.

It would probably require civil rights to roll back a bit. Gattaca showed a society where the disabled (or even people simply predisposed to potential hereditary problems) literally lost rights and were given menial jobs. Scary as it seems with the realism behind the study of genetic research and manipulation, current society doesn't give two shits about hereditary disease as long as you can do the work and the disabled are outright encouraged to succeed and show their full potential in spite of their physical or mental problems. Not to mention that we're making very rapid headway in equal rights for all citizens (much faster than historical precedent before the 20th century). Gattaca would require society to simply drop all accomplishments made with civil rights and attempts to help the disabled and become perfectly fine with their friends and family being denied opportunity based on genetic profiling that isn't 100% accurate.

If they've got DNA handy, that's the first step. The biggest problem even if you can get DNA for cloning is finding an egg that can properly develop into a healthy baby. Cloned animals also tend to have a lot of problems due to the natural imperfections in the DNA; the biggest is premature aging, as the telomeres in the cells have already shortened with age because they're taken from another animal. If we could figure out how to keep telomeres from shortening, cloning's hardly our biggest advance. We'd have just discovered the cure to aging.
