WOW!  game changer!  Thanks for sharing Rajini Rao !!
 
How to Boil Water

❉ In breaking news, scientists have figured out how to boil water - at least 3 times more efficiently and producing twice as much steam. Before you shake your fist at "wasteful research spending", this isn't really about your whistling tea kettle! 

❉ Phase change heat transfer processes (boiling, condensation) are a big part of everyday technology from water purification and HVAC units, power plants and cooling electronics.   When water boils, a thin layer of steam can coat the heated surface, insulating it and drastically cutting down on the efficient transfer of heat to liquid. This can lead to surface burnout and a destructive condition known as critical heat flux. What is needed is a surface that discourages the vapor from sticking and wicks in water to quickly re-wet the heated surface. To create a superhydrophilic wicking surface, Drexel University scientist Matthew McCarthy turned to biotemplating with....viruses! 

❉ The tobacco mosaic virus causes mottling of tobacco leaves, as its name implies, but is harmless to humans. It was the first virus ever to be discovered (in the late 1880's) and is constructed simply of repeating units of a coat protein, wrapped around a single, helical strand of genetic material (RNA). A few tobacco plants can produce billions of virus particles, so it's cheap to make. Dr. McCarthy tweaked the coat protein so it sticks to any engineered surface- from silicon to steel. After dunking the surface in a viral broth, nickel and palladium are added to grow a metallic grass

❉ The viral tendrils work like a wicking surface, drawing down water to replace what's boiled away.  It's the same idea behind thermal fabrics designed for athletes which draws moisture away from the body. They say a watched pot never boils. I'd volunteer to test a virally coated tea kettle, how about you? 

Waterproofin' with Hydrophobin: This old post shows how a fungal spore protein can do the opposite, creating a superhydrophobic surface that repels water but allows gases to exchange.

It's my mom's dream to visit the Fjords, and I'd love to be the one who takes her there!
 
Magnific landscape, the Fjords, very beautiful place!

First carbon fiber 3D printer?  Love to see some raw print examples from the Mark One!
 
"Brilliant ideas need brilliant materials.
Designed to overcome the strength limitations of traditional 3D printed materials, the revolutionary Mark One 3D printer is the world's first 3D printer designed to print continuous carbon fiber. Now you can print parts, tooling, and fixtures with a higher strength-to-weight ratio than 6061-T6 Aluminum."

This pale blue dot is not Earth, but the 200 light years diameter about Earth into which human radio wave communications have dispersed so far. It's really small, isn't it? And it's worth remembering, though likely impossible to comprehend, that the extent of the visible universe contains an estimated minimum 100 million galaxies, of which the imaged Milky Way is just one.

Another post reported the finding of a planet smaller than our own orbiting (130 days) within the habitable region of a star smaller than our Sun 500 light-years away from our home planet. This picture helps give you a sense of how close and how far the Kepler discovery is from us, about two and one-half times the radius of the little blue dot!

This is the tri-corner intersection of Harris County (Houston, TX), Fort Bend County and Waller County in Katy, Texas.  This shows the Waller side of the old monument post with my GPS resting on top of it.  Each of the full stone pavers is six inches long and each full brick is 12" long, for scale.

Another year, another 2 parts per million.  December 2015 we will see over 400 ppm as the global average, with quite a bit more than that during the winter die-off in the northern high latitudes.

Another year, another 2 parts per million carbon dioxide residing in Earth's atmosphere.  By December 2015, the globe will average above 400 ppm while during the winter die-off the high northern latitudes will be sitting under quite a bit higher concentrations than that.

It's not easy to remember that at all times we ourselves consist of the dust of ancient exploded stars, as are the larger accumulations on which we and all life ride, swim and breathe, and that this our home planetary solar system circulates in an eddy 2/3 out along one arm of a trillion-star galaxy among some hundred billion galaxies within our limited perception of light (electro-magnetic radiation).  Thanks for the beautiful reminder, Brandon Leibowitz!
