Less than 24 hours after Olympic onlookers watched the Rio diving pool turn a murky shade of green, it now looks like the water polo pool is slowly growing something, too.
As the women's synchronised diving teams took to the pool in Rio de Janeiro today, they were greeted by a strange sight. The diving pool had turned green overnight, while the neighbouring water polo pool remained a crystal clear blue. This confused the Olympic organisers, media, and the internet profusely. Long story short: It's most likely an algae bloom.
From powering aeroplanes to replacing nuclear energy, algae has been touted as a green energy miracle. So if our waterways are already filled with the stuff, why isn't it filling the world's skies with biofueled planes? Algae is a tricky creature that presents a lot of challenges and misconceptions. Here's why it's difficult to harness — and why it could big a big payoff.
Long ago, a clan of hardy microbes called cyanobacteria helped terraform the lifeless Earth into a vibrant biosphere. Today, the very same critters could be the key to colonizing Mars.
The image above, "Eye of an Algal Storm" was captured by the European Space Agency's Sentinel-2A satellite over the middle of the Baltic Sea on 7 August. With a spatial resolution of just 10 metres, ripples and waves are captured in stunning detail. In the top centre of the image, you can even make out the wake of a ship as it slices through cyanobacteria-laden waters.
A highway overpass is the last place most of us would think to install a farm. But algae, that wonderful little ecological miracle, is different. Since it consumes sunlight and CO2 and spits out oxygen, places with high emissions are actually the perfect growing area. Which is why this overpass in France has its own algae farm.
Bioluminescence is awesome. Essentially the production of light by a living organism, e.g. fireflies, certain types of jellyfish, etc — but it doesn't just occur in animals. There's even some plant life that has the potential to give off that lovely, ethereal glow. And as Mark Rober shows us in the video above, you can even harness that power to become your very own natural, eerie, and totally beautiful light source.
