Last weekend I had the pleasure of talking to the Italian paralympian Martina Caironi. For those of you who might not know her, she won a Gold Medal in London in the 100 mtr T42 category in a new World Record time, Gold in the World Championships in the long jump and again in the 100 mtrs, and just last month took the World Record over 200 mtrs. This is her in the photo above, she is the fastest para-athletic woman on Earth.
We have all heard about the problem of the oceans getting cluttered up with plastic. Unfortunately, solving the problem of marine plastic pollution is not as simple as picking up all of the pieces of plastic. While a lot of plastic pollution is concentrated in the gyres, it is not floating in a single mass on the surface. Pieces of plastic are distributed vertically, through the water column. Plastic breaks down into tiny particles in the ocean, making clean-up efforts very difficult. One of the many challenges of cleanup is how to remove the plastics from the ocean without also removing or damaging marine life.
This week I want to put two of my little pets together. Nanotechnology and food might sound like two very different topics, like a cat and a gerbil to use the pet metaphor, but you would be surprised. Many products in fact have manufactured nanoparticles in them, and we eat them.
Now we might ask if this is safe, and some would say of course it is. Some have great reservations about it, and some point to the fact that there has been little research done into the matter and that it might be better not to eat them anyway.
The days of discovering planets by pointing a telescope at the skies are long gone. If you are interested in discovery you can join the Galaxy Zoo project.
The Galaxy Zoo project has been running for several years, and involves hundreds of thousands of people. One of the problems for scientists today is the analysis of the enormous amounts of scientific data generated. This example is that of The Hubble telescope. It captures such a large amount of images that they risk never being studied, but one way of getting round this problem is to invite non scientists to view the pictures online and classify what they see. The tutorial on their website is simple to follow and in a few minutes you are away and participating in scientific discovery.
There is always the possibility of finding something new too, as in the example of the dutch primary school teacher Hanny Van Arkel who now has an object known as “Hanny’s Voorwerp” named after her, an object that would probably never have been noted had it not been for Ms Arkel’s lay interest in star gazing.
Time moves like molasses as they say here, but it moves.
Almost exactly a year ago I wrote a post called Mining the Seabed. Almost exactly a year before that I wrote a post about the possibility of sending robots to mine asteroids. All science fiction I heard you say, but oh wait.
As regular readers may know, I am currently living my life straddled between two continents. I am based in Boston in the USA, but technically resident of Italy. To add to the confusion I am going to live in the Netherlands in June.
Why the Netherlands? I hear you all ask in unison. Bikes and technological advances in road safety might be one reason (although there are also others).
So first to bikes. I am a cyclist myself, I ride a 1973 Triumph 3 speed, it is a lovely machine. This winter has been a harsh one though, even for Boston standards, and the roads and pavements were covered in ice for long periods of time. As in many other places the city council sends trucks out to throw salt all over the place, which is not very good for the roads, cars, or water supply.
Today is Earth Day. It is the 44th time that we celebrate this planet that we call home. The celebration started in 1970, and is the brain child of US Senator Gaylord Nelson.
Nelson asked Denis Hayes to organize a day of awareness, on April 22nd, and by the end of 1970, the U.S. Environmental Protection Agency had been established, and efforts to improve air and water quality were gaining political traction.
Today is a time of celebration, of love for our little speck in space. And it is a lovely speck, there are some quite beautiful places to see and experience dotted across the surface.
