Yet these things generate up to 50 percent of the oxygen produced on the planet each year and make up about half of the organic material found in our oceans.
What amazes and delights this non scientist, is the relatively small magnifications required to examine life in such radically revealing ways.
So many of the images that are captivating me have been taken at between 50 and 100 times magnification.
This makes me think about how close human perception is to the ability to gain access to a vastly expanded understanding of our world, and yet we seem to have been made to live in a different scale of existence, one that maybe makes us the ideal scale for shaping the world around us with physics, but I am prompted by these images to wonder how much more sympathetic with our environment we might have been, had we ability to see even a little way into the micro scale.
As a former photographer and in advertising, but as a child you wouldn't have bet against me pursuing a career in the sciences and particularly biology and botany, I must particularly rue the relatively poor availability of photographic tools for micro photography. Macro and micro lenses almost disappeared from catalogues about the time when autofocus was introduced. Minolta sold the only 1-3 times magnification autofocus lens and I've never seen one. Only last month, Sony started selling the adapter that can enable Sony Alpha cameras to attach and correctly use old A mount lenses.
It's not quickly easy to find information about photomicography, but in case it's missed the Small World website links to this very good resource:
I've had many hours of enjoyment collecting moss and finding tardigrades, rotifers, and so many other experiments. Using a DSLR adapter and watching the results externally makes things much more comfortable (although you lose the stereo effect).

Without knowing which images you are referring to it's hard for me to say, but on many of the images I looked at that was only the objective lens magnification, so not the total magnification which includes the eyepiece magnification, typically 10x.
I wonder how plausible it is to genetically engineer algae to sequester more carbon e.g. make them bigger and heavier so they sink to the bottom of the ocean, and also make them reproduce faster.
Engineering RuBisCO (the enzyme in charge of carbon fixation and the rate-limiting step in photosynthesis) has been quite difficult, as some side reactions generate products that, for instance, inhibit RuBisCO itself. If you make the fixation reaction more efficient the other ones follow.
Another option is increase the amount of RuBisCO in the cell. In cyanobacteria the enzyme is encapsulated in compartments called carboxysomes. Some studies have introduced carboxysome-like components in non-cyanobacterial organisms with varying results.
They live in a hugely competitive environment. Any custom algae that weren't as competitive as natural ones would soon die out, and it's pretty hard to beat nature at its own game...
Many of the crystal photos wouldn't be too hard to reproduce on your own- a reasonably good microscope (Amscope) costs about $1K or less on Amazon, you need an adapter to plug in a DSLR, and a DSLR ($500). Then it's mainly a matter of mixing up supersaturated solutions. I've managed to get images of sugar forming crystal towers, which is fun to watch.
riffing off the 60's light show, sorry. The Lucy in the Sky part of Yellow Submarine is no longer up on Youtube, and I was too lazy to search out the old analogue days.
