Scientists have grown the embryos of a extinct species

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.

And now I'm thinking of the Lazarus Pit.

...Assuming the DNA of a neanderthal was available, would they be able to grow one in a human or something?  :o

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.
