Oregon State University researchers created and patented a new strain of the protein-rich red marine algae known as Dulse. When cooked, this new stuff really tastes like bacon. The engineered strain is high in protein, and purportedly offers twice the nutritional value of everyone's favorite vegetable-du-jour, kale. Read the rest
This is a picture of a wave crashing on the New Jersey shore. It glows because of dinoflagellates — little, single-celled plants, animals, and bacteria that float around on the water, moving about with the help of long, moveable protein strands called flagella. Some dinoflagellates are bioluminescent; that is, chemical reactions inside their bodies produce light. The result is glowing oceans. Or, as maker Caleb Kraft recently discovered, the dinoflagellates also make for a soft blue nightlight with really nifty special effects.
You can watch Kraft's nightlight project at YouTube. It's pretty simple to do at home. At it's most basic, all you need to do is purchase some bioluminescent dinoflagellates online, keep them alive in your home, and give them a good shaking occasionally to trigger the chemical reaction.

Beachgoers in Qingdao, Shandong province, China, were met with a fuzzy, green blanket of ocean last week, as the water there exploded with algae.
You've heard before about dead zones. These are patches of coastal ocean where river runoff full of fertilizer chemicals have produced massive algae blooms. As the algae die, their decomposition reduces the oxygen level of the water to the point that many fish and other aquatic life can no longer live there.
This is what a dead zone looks like, just before the death.
It's worth noting, when I pulled this photo out of the Reuters files, I could see similar shots, taken on the same beach, in 2010, 2009, and 2008. This isn't a fluke. It's an endemic problem.
