The problem is, of course, that we don’t have a cloned Neanderthal. Which is why we need to make one

The surface of the earth is the shore of the cosmic ocean
Recently we’ve waded a little way out
And the water seems inviting

Il nostro mondo si fa sempre più complicato e ad ognuno occorre una competenza sempre più affinata e aggiornata. I mestieri pericolosi sono molti e l’analisi dei pericoli (palesi ed occulti)
dovrebbe costituire l’alfabeto di ogni formazione professionale.
Non si riuscirà mai ad annullare tutti i rischi né a risolvere tutti i problemi ma ogni problema risolto è una vittoria, in termini di vite umane, salute e ricchezze salvate.
La competenza non ha surrogati
La buona volontà, il coraggio, lo spirito di sacrificio, l’ingegno estemporaneo non servono molto, anzi, in mancanza di competenza, possono essere nocivi.
Microbes survive 30,000 years inside a salt crystal - life - 22 December 2009 - New Scientist →
THRIFTY microbes entombed in a salt crystal have survived for 30,000 years by feeding off the remains of algae that were trapped along with them. This is the most convincing example to date of long-term survival. Brian Schubert, a microbiologist at the University of Hawaii at Manoa, and colleagues studied salt crystals in a sediment core taken from Death Valley in California. The crystals contained tiny pockets of liquid, and the team found that they could grow live colonies of archaeans from samples of it. The team dated the liquid at between 22,000 and 34,000 years old (Geology, vol 37, p 1059).

Could we create quantum creatures in the lab? - physics-math - 15 September 2009 - New Scientist →
In quantum theory, a single object can be doing two different things at once. This so-called “superposition” is a delicate state, destroyed by any contact with the outside world. The largest objects that have been superposed so far are molecules. It is hard to put a much larger object such as a cat or human into a superposition because air molecules and photons are always bouncing off it
il Bloop !
IN THE summer of 1997, an array of underwater microphones, or hydrophones, owned by the US government picked up a strange sound. For a minute, it rose rapidly in frequency; then it disappeared. The hydrophones, a relic of cold-war submarine tracking, picked up this signal again and again during those summer months, then it was never heard again. No one knows what made the sound, now known as “The Bloop” (hear it at www.thebloop.notlong.com).
