Con un'operazione che ricorda vagamente quella portata a termine nel film "Jurassic Park", alcuni scienziati coordinati da uno specialista dell'Istituto di ricerca sul sangue di San Francisco sono riusciti a resuscitare un virus ibernato nelle feci di un caribù vissuto 700 anni fa in Canada.
Il microrganismo è poi stato iniettato in una pianta, riuscendo a infettarla.
Si tratta di un risultato molto interessante poiché la "riesumazione" ha permesso di studiare materiale genetico di antiche entità biologiche, rarissime da trovare in campioni intatti, e di ripercorrerne l'evoluzione.
