2107-08-01 (Mother Nature’s son)

Today, I learned that:

Regardless of what we say and think, we still respond to Her (Mother Nature). Sometimes She shares with us the most amazing scenarios, such as the one in today’s header photo. It shows a countryside highway with bamboo trees on both sides. And if you can read Portuguese, then you understand that this place is a sanctuary for wild animals. The road sign depicts an ocelot, and furthermore there is an alert that this is a road with a high degree of crashes between cars and animals. The location is close to the city of Assis, state of São Paulo, Brazil, where there is an ecological station.

It seems like a perfect coincidence that it is located in Assis, because as you probably remember, in a similarly sounding town in Italy, during the 12th century, there was born a person who later would be known as Saint Francis of Assisi. Among other things, he is known for his friendliness to the birds and in 1979 Pope John Paul II declared him the Patron Saint of Ecology. (The current Pope Francis I also honoured him by adopting his name as his own papal name.) See references #1 and #2 below.

But Mother Nature does not only present us with beauty, She is also very practical. Last Friday, I was reminded twice of that, when Radio Sweden interviewed professionals involved with creating and using practical solutions from Her in favour of humanity.

In the morning, I was told about a new kind of glue, which will permit heart surgeons to glue parts together within a beating heart. The origin of that invention is in the slime produced by a slug, which inspired scientists at Harvard. Hear and read about it in reference #3 below (Swedish), as well as read about in reference #4 (English).

Then in the evening, another sensational feat. As long as we can remember, the spider has impressed us with its production of ultra-thin, yet extremely strong threads. And now Swedish scientists have discovered a way of recreating such production without using toxic chemistry. Reference #5 contains an audio interview in Swedish with Anna Rising, one of the scientists, and reference #6 is a written interview in English, where she and her fellow colleague Jan Johansson explain more.

Then, over the weekend, I remembered a similar story from exactly 10 years ago. By using practical solutions from a gecko and a mussel, scientists at Northwestern University were able to create a glue that would stick well also under water, see reference #7 below. And in the beginning of 2017, see reference #8, was reported how the very same gecko had inspired researchers at Kiel University to invent a method of immediate grip and release.

But wait, there is more! As a bonus, look also at this article from 2010, reference #9 below, which reports about a combination of mussel glue and nanoparticles to create a proactive cover against corrosion.

To end today’s post, what could be better than listening to the fantastic song writher John Denver, so tragically gone in 1997, to describe his love to Mother Nature! See and here his poem in reference X below.

… That’s what I learned in school !
