Hippocampus | Tamily Weissman

"Brainbow" mice are engineered with a gene that includes three different fluorescent proteins, but only one color is actually expressed from each copy of the DNA construct. Pairs of "incompatible lox sites" are nested around different portions of the gene, allowing for recombination to snip out different parts of the gene randomly. Depending on what DNA is excised, a different color results.

Oh, tiny garden. How pretty thou art.

Turbulence is an excellent mixer. Here two fluorescent dyes are injected into a turbulent water jet. Flow is from the bottom of the image toward the top. The dyes are quickly mixed into the background fluid by momentum convection, their concentration decreasing with increased distance from the source. Large-scale structures like the eddies visible in this image drive this convection of momentum in turbulent flows. In contrast, consider laminar flows, where momentum and molecular diffusion dominate how fluids move. In such laminar flows, it’s even possible to unmix two fluids, a feat that cannot be accomplished in the jet above. (Photo credit: M. Kree et al.; via @AIP_Publishing)

The Moon on December 7, 1992, in a false-color mosaic built from 53 images taken through spectral filters by Galileo’s imaging system as the space probe flew over the northern lunar regions: “Bright pinkish areas are highlands materials, such as those surrounding the oval lava-filled Crisium impact basin toward the bottom of the picture. Blue to orange shades indicate volcanic lava flows. To the left of Crisium, the dark blue Mare Tranquillitatis is richer in titanium than the green and orange maria above it. Thin mineral-rich soils associated with relatively recent impacts are represented by light blue colors; the youngest craters have prominent blue rays extending from them.” (via)

Bees Close Up.

There are over 20,000 species of Bees either in solitary existence or within social communities and they are possibly one of the most important insects to us as a species. More on Bees here, here and here.

Yep, we did reblog this before, but we didn’t have quite so many images. I love the way the sheets of plant cells seem to form disparate planes in that last one. —MN

The Amazing Technicolor Landscape of Mars

High resolution digital terrain models, or DTMs, are topographic maps of Mars as imaged by the High-Resolution Imaging Science Experiment (HiRISE) on board NASA’s Mars Reconnaissance Orbiter (MRO). They are created by grabbing two separate images of the same region of the Martian surface during different orbits. These “stereo pairs” (with different angles of inclination) are used to precisely measure the elevation of the landscape after a complex and time consuming series of steps including calibration by mission scientists and calculations by a powerful algorithm. The result is nothing short of beautiful. So get immersed in Mars’ technicolor landscape and see the scale of some of those awesome geological formations on the Red (blue, green and yellow) Planet.
