This will take us away from the daily beat of life!
On the 18th. February the BBC News website carried an article that I found incredible. It was the story of Naica’s crystal caves in Mexico.
Naica’s crystal caves hold long-dormant life
By Jonathan Amos, BBC Science Correspondent, Boston, 18 February 2017.
It is a remarkable discovery in an amazing place.
Scientists have extracted long-dormant microbes from inside the famous giant crystals of the Naica mountain caves in Mexico – and revived them. [Ed: my emphasis]
The organisms were likely to have been encased in the striking shafts of gypsum at least 10,000 years ago, and possibly up to 50,000 years ago.
It is another demonstration of the ability of life to adapt and cope in the most hostile of environments.
“Other people have made longer-term claims for the antiquity of organisms that were still alive, but in this case these organisms are all very extraordinary – they are not very closely related to anything in the known genetic databases,” said Dr Penelope Boston.
The new director of Nasa’s Astrobiology Institute in Moffett Field, California, described her findings here at the annual meeting of the American Association for the Advancement of Science (AAAS).
I was delighted to find more details in many other places on the ‘web’.
Such as this one on the National Geographic website:
PUBLISHED February 17, 2017
Creatures that thrive on iron, sulfur, and other chemicals have been found trapped inside giant crystals deep in a Mexican cave. The microbial life-forms are most likely new to science, and if the researchers who found them are correct, the organisms are still active even though they have been slumbering for tens of thousands of years.
If verified, the discovery adds to evidence that microbial life on Earth can endure harsher conditions in isolated places than scientists previously thought possible. (See “Life Found Deep Under Antarctic Ice for First Time?”)
“These organisms have been dormant but viable for geologically significant periods of time, and they can be released due to other geological processes,” says NASA Astrobiology Institute director Penelope Boston, who announced the find today at a meeting of the American Association for the Advancement of Science. “This has profound effects on how we try to understand the evolutionary history of microbial life on this planet.”
Then there’s another article on that NatGeo website: (Apologies for some duplication in the message.)

In a nearly empty cantina in a dark desert town, the short, drunk man makes his pitch. Beside him on the billiards table sits a chunk of rock the size of home plate. Dozens of purple and white crystals push up from it like shards of glass. “Yours for $300,” he says. “No? One hundred. A steal!” The three or four other patrons glance past their beers, thinking it over: Should they offer their crystals too? Rock dust on the green felt, cowboy ballads on the jukebox. Above the bar, a sign reads, “Happy Hour: 8 a.m. to 9 p.m.”
This remote part of northern Mexico, an hour or so south of Chihuahua, is famous for crystals, and paychecks at the local lead and silver mine, where almost everyone works, are meager enough to inspire a black market. “Thirty dollars.” He leans in. “Ten.” It’s hard to take him seriously. Earlier in the day, in a cave deep below the bar, I crawled among the world’s largest crystals, a forest of them, broad and thick, some more than 30 feet long and half a million years old. So clear, so luminous, they seemed extraterrestrial. They make the chunk on the pool table seem dull as a paperweight.
Nothing compares with the giants found in Cueva de los Cristales, or Cave of Crystals. The limestone cavern and its glittering beams were discovered in 2000 by a pair of brothers drilling nearly a thousand feet below ground in the Naica mine, one of Mexico’s most productive, yielding tons of lead and silver each year. The brothers were astonished by their find, but it was not without precedent. The geologic processes that create lead and silver also provide raw materials for crystals, and at Naica, miners had hammered into chambers of impressive, though much smaller, crystals before. But as news spread of the massive crystals’ discovery, the question confronting scientists became: How did they grow so big?
It takes 20 minutes to get to the cave entrance by van through a winding mine shaft. A screen drops from the van’s ceiling and Michael Jackson videos play, a feature designed to entertain visitors as they descend into darkness and heat. In many caves and mines the temperature remains constant and cool, but the Naica mine gets hotter with depth because it lies above an intrusion of magma about a mile below the surface. Within the cave itself, the temperature leaps to 112 degrees Fahrenheit with 90 to 100 percent humidity—hot enough that each visit carries the risk of heatstroke. By the time we reach the entrance, everyone glistens with sweat.

Finally, lose yourself in this video. (If the voice doesn’t get to you!)
How to close today’s post?
Both by embracing the power of the natural order of things, life and death, and by reminding us all that there are in the order of over two billion stars in this universe.
That universe must be teeming with life, current and dormant, and the day when we truly confirm that will put everything into perspective!
Talk about synchronicity!
For yesterday, around 10am PST, the BBC News website carried this big news item: Earliest evidence of life on Earth ‘found’.
Here’s how that article opens:
Earliest evidence of life on Earth ‘found’
By Pallab Ghosh Science correspondent, BBC News
Scientists have discovered what they say could be fossils of some of the earliest living organisms on Earth.
They are represented by tiny filaments, knobs and tubes in Canadian rocks dated to be up to 4.28 billion years old.
That is a time not long after the planet’s formation and hundreds of millions of years before what is currently accepted as evidence for the most ancient life yet found on Earth.
The researchers report their investigation in the journal Nature.
As with all such claims about ancient life, the study is contentious. But the team believes it can answer any doubts.
The scientists’ putative microbes from Quebec are one-tenth the width of a human hair and contain significant quantities of haematite – a form of iron oxide or “rust”.
Matthew Dodd, who analysed the structures at University College London, UK, claimed the discovery would shed new light on the origins of life.
