Science Upended Again: The Fountain of Youth and Living Clouds

Just when we think that we have a grasp on what's possible — on the outer limits of what science is likely to achieve or learn — something comes along to turn all that on its head. If, like many people (including myself), you thought that science would probably never discover anything resembling a fountain of youth, it turns out you were wrong. Not only have scientists recently succeeded in slowing down the aging process in mice, they have actually reversed it.

According to PopSci, scientists at Harvard "turned unhealthy old mice into youthful versions of themselves." Ronald DePinho, the lead scientist working on the project, told the Guardian:

"What we saw in these animals was not a slowing down or stabilisation of the ageing process. We saw a dramatic reversal – and that was unexpected... These were severely aged animals, but after a month of treatment they showed a substantial restoration, including the growth of new neurons in their brains."

Lake Mono in California

Other perspective-altering events that have occurred in the science world recently:

• The discovery of arsenic-based life in Mono Lake in California. This has shaken the biology world, suggesting that a previously unconsidered and entirely unexplored biosphere exists all around us, essentially redefining the meaning of 'life'. It has led some to consider again the possibility of living clouds. Seriously.

• A newly-identified species of bacteria, found in the wreckage of the Titanic, which eats steel.

• The Big Bang was the beginning of the universe, right? Two astronomy theorists say 'not so fast'. One of them, Britain's Sir Roger Penrose, has been getting some press lately with his assertion that there might have been many Big Bangs, in a repeating and possible never-ending cycle. He even purports to have evidence.

• As previously reported on TalkingSkull.com, the third dimension might just be an illusion.

Reading through all of these developments, I keep hearing in my head a line from Operation Ivy's song Knowledge: "All I know is that I don't know nothing." Despite the boundaries that we try to draw around the world we think we know, those boundaries come easily crashing down in the wake of new information. As our columnist Hewy pointed out recently, we really don't know much of anything.
