Comparison of galactolipid biosynthetic pathways in cyanobacteria, red algae, and green plants. The mgdE gene encodes the epimerase that catalyzes the conversion of glucolipids (GlcDG) to galactolipids (MGDG). Only cyanobacteria have this gene. In contrast, in red algae and green plants, MGDG is directly synthesized by transfer of galactose to diacylglycerol. © 2014 Naoki Sato. #UTokyoResearch

Superresolution image of the anti-diabetic protein complex in beta cells. KIF12 kinesin (green) simultaneously binds to the stress-regulating protein (blue) and its transcription factor (red) to maintain their expression levels. Overnutrition may disrupt this complex by KIF12 downregulation, resulting in progress of diabetes. © 2014 Wenxing Yang, Yosuke Tanaka and Nobutaka Hirokawa. #UTokyoResearch

Slime Mold - Alien Landscapes On Earth ~ Kuriositas

The base of an evolutionary tree diagram is composed of three bacterial lineages, each represented by a colored branch: the Cyanobacteria lineage is shown in blue; the Proteobacteria lineage is shown in red; and the Archaebacteria lineage is shown in purple. Mitochondria in eukaryotic lineages evolved over time as an archaebacterial host incorporated an ancient proteobacterium as a symbiont inside its cell. Eukaryotic chloroplasts evolved as ancestral eukaryotes acquired ancient…

An illustration of magnetic-field configuration of a magnetar. Dark blue curves indicate dipolar magnetic field lines that are externally observable, while red curves indicate toroidal field lines confined within the star. The dark-blue and red field lines cause oblate and prolate deformation, respectively. Possible regions of the soft and hard X-ray emission are indicated in green and orange, respectively. © 2014 Toshio Nakano and Kazuo Makishima. #UTokyoResearch

Ancient plants 'frozen in time' by space impacts

Ancient plant material was perfectly preserved in the glass formed when asteroids hit the Earth millions of years ago, scientists report. The "frozen in aspic" appearance of what are apparently blades of grass is spectacular enough. But a team writing in Geology journal says that delicate organic chemicals have also been conserved inside.
