It wasn't his physical fitness that was subpar, although that did require some post-op retraining, but rather his mental capacity.

Whatever Happened to the Mars Rovers?
Natural Quasicrystals First cooked up in the lab in 1984, quasicrystals are unusual substances that lie somewhere between the crystalline and the amorphous.

Live recordings of cell communication
A new method for nanoscale imaging of vesicle-fusion -- vesicles are biological nanosized containers -- could add to our understanding of diseases of the nervous system and viral infections. This could be useful in developing a cure for neurological diseases and mental disorders.

Unstable proteins can cause premature ageing
The normal aging process has long been linked to problems with cell respiration, the process through which the cells extract energy from nutrients. Researchers at the Swedish medical university Karolinska Institutet have now shown how certain proteins that are synthesized in the cellular mitochondria -- popularly known as the cells' power plants -- become unstable and disintegrate, which in turn can impair cell respiration and cause premature aging.

Chicken-hearted tyrants
It will break every pre-schooler's heart: Tyrannosaurus rex and other predatory dinosaurs might not have been fearless hunters after all. Based on fossil evidence researchers at LMU Munich propose that the large carnivores hunted mainly juvenile dinosaurs instead of giant herbivorous adults.
