Lovely images of glowworms from the cave of New Zealand – which I used in a book (can you name it?) The bioluminescent blue light is produced by the larval stage of a fungus gnat – and is used to attract prey to the sticky mucusy ‘fishing lines’ the larvae string throughout these caves on the North Island of New Zealand. Truly an eerie sight. 
These new shots show the otherworldly magic created by a carnivorous fungus gnat

From the Big Bang to the Big Rip? New models that take into account cosmic viscosity (stickiness) envision the death of the cosmos in a Big Rip, where the expansion rate of the universe accelerates until objects begin to fall apart and atoms disassemble into elementary particles and radiation…
Mathematicians and physicists have come up with a new approach to calculate cosmic viscosity and the formulation favors the 'Big Rip' scenario for the end of the universe.

Dolphins in space…Throwback Thursday looks at Startide Rising, “From the space battle that rages overhead to gain control of a crashed maiden voyage of a dolphin spaceship, to the complex relationship that humans have with the rest of the universe, this book is nonstop science-fiction/action goodness.”

That book is beyond awesome.  If you haven't read it, do yourself a friggin' favor.

Science or science fiction? Will we ever build ringworlds or Dyson spheres? 
Immense floating structures could become humanity’s home, harnessing the power of stars. But, Peter Ray Allison writes, building them will be a colossal challenge.

Interesting... for the discussion of ringworlds, the article didn't even mention that clith (the fictional material that Niven's Ringworld is made out of) would need a tensile strength on the order of the strong nuclear force.

A look at some of the space habitats portrayed in science fiction, from Deep Space 9 to Elysium….are they plausible?
Humanity’s future in space very much in the planning stages. Will we float among the stars in crazy spaceships? Will we set up small camps that sprawl into townships that grow into cities, or is an orbital mothership more human friendly? The question is, could any of these really be possible? Or do they deserve to be forever enshrined as sci-fi fever dreams?

Uplifted baboons? Signs of democracy seen in typically authoritarian baboon society: wild baboons apparently make democratic decisions when deciding where to travel…
When it comes to where to travel, the primates vote with their feet

When they decide collectively to go to the local baboon strip club, then we know we're in trouble!

Nice summary of the oceans in our solar system:  from the subsurface oceans on the dwarf planet Ceres to Jupiter’s moons Europa, Ganymede and Callisto and Saturn’s moons Titan and Mimas.

When scientists looked at Mars through early telescopes, they saw a fuzzy, rust-colored globe scored by mysterious dark gashes some believed were alien canals. Later, armed with sharper images, we scoffed at such naiveté.... read more

Wow.  Uttergloss!  A video animation of dwarf planet Ceres, based on images taken by NASA's Dawn spacecraft, provides dramatic flyover views of this heavily cratered, mysterious world. Note: YOUR civilization did this.  Just part of the best year in space exploration since the 1970s.
