For the sixth year in a row, green algae have invaded the beaches of Quingdao, China (video). This year's algal bloom covers 28,900 km² (about the size of Massachussets or Albania), more than twice the 2008 record (13,000 km²). Bonus: two research papers (PDF) dealing with the identification of the species (Ulva prolifera) and the origin (possibly aquaculture ponds on land) of the 2008 bloom (5 years ago on MeFi).
The Puzzle of Plastid Evolution: A comprehensive understanding of the origin and spread of plastids remains an important yet elusive goal in the field of eukaryotic evolution. Combined with the discovery of new photosynthetic and non-photosynthetic protist lineages, the results of recent taxonomically broad phylogenomic studies suggest that a re-shuffling of higher-level eukaryote systematics is in order. Consequently, new models of plastid evolution involving ancient secondary and tertiary endosymbioses are needed to explain the full spectrum of photosynthetic eukaryotes.

Global warming quick fixes roundup, featuring the new water spray cooling method. There's also biochar carbon sequestration for the soil, or perhaps growing reflective crops, or growing crops with seawater in barren deserts. For the oceans, we have iron fed green algae management, and crop waste dumping too. In the skies, there's sunshading to reflect the problem rays, or perhaps a volcano simulation by filling the atmosphere with sulphur. Finally, there's an idea for a three-mile high superchimney that does it all.
