“La NOAA, la célèbre agence états-unienne responsable de l’étude de l’océan et de l’atmosphère, vient de rendre public son rapport annuel sur l’état de l’Arctique. Il révèle, par exemple, que les températures de l’air s’y élèvent deux fois plus vite que celles de la moyenne globale.”

Scientists race to save 'genomic books' in the burning 'library of life'

Scientists race to save 'genomic books' in the burning 'library of life' | Science pour tous | Scoop.it

Researchers at the ARC Centre of Excellence for Environmental Decisions (CEED) have developed a cost-effective way to save a wide range of threatened species, including rare old ones that may be costly to protect. Their new technique to help maximise both the species and genetic diversity we save helps resolve the dilemma facing conservation managers worldwide: whether to rescue a larger number of recent and more common species or fewer, unique and older species that may be more costly to preserve.


The technology will help nations such as Australia and New Zealand to protect as much diversity of both species and their genes as possible, says lead researcher Dr Joseph Bennett of CEED and The University of Queensland (UQ). "The global extinction crisis is getting worse, and conservation funds are seldom enough to stop biodiversity from declining," says Dr Bennett. "This is like a library on fire – and we have to save as much of the precious information as we can.


"If we have to choose, do we carry out a few rare, old tomes, or do we carry a larger number of smaller books that may contain less information than the ancient tomes?" Dr Bennett explains that highly distinct species have few close relatives, and their lineage has been isolated on the tree of life for many millions of years. The platypus is one example of Australia's 'rare old tomes' – its ancestors diverged from other mammals somewhere between 160 and 200 million years ago.


As the distinct species are isolated from others, they also contain unique genes, which may in the future prove very important to the health of ecosystems, or even the development of medicine. For example, Ginkgo biloba is an old and genetically distinct species that was once close to extinction, but is now used traditional medicine, he says.


"So losing the more distinct species – akin to losing the rare old tome – could mean the loss of this genetic information, along with millions of years of evolution," he says. "But when these species are expensive to protect, it may mean spending money to save one or two species instead of five or ten other species."

The amount of ebooks being produced, we will soon have to take up the same exercise with real books in the real libraries of life

Voilà, il fallait bien que cela arrive.Que – par une pirouette ironique de l'histoire – des textes devenus numériques en raison du manque d'intérêt de la presse classique pour la vulgarisation scientifique suivent le chemin inverse et se transmutent...
