After a couple of cold, stormy nights, my favorite spider has disappeared from the shed.
Only a sheet of ice protects you from falling 1000 feet down this Abyss
Photographer Aaron Huey, who is on assignment for National Geographic, recently shared a picture of a frighteningly deep hole on the Lower Ruth Glacier. The only thing stopping people from plummeting down the 1000 feet drop into the ground is a sheet of ice. One crack, though.
Staring down what could be a 1,000ft deep worm hole through the blue ice of the Lower #RuthGlacier. I was never afraid of the ones full of water, they’d just be cold, but some had no water and it was easy to imagine a long slide to an icy death. #yikes (on assignment for @natgeo in #DenaliNationalPark)http://sploid.gizmodo.com/only-a-sheet-of-ice-protects-you-from-falling-a-1000-fe-1614438185/all
I would have never guessed what these beautifully illustrated objects represent. They remind me of molecules and atoms or the various forms in which snowflakes appear to us. But instead of adding a beautiful white layer to the world, these little creatures can cause some of us a lot of trouble during the summer. Ueber den Pollen was published in 1837 by St. Petersburg based German pharmacist and chemist Carl Julius Fritzsche. Here you can flip through the whole book.

Wildlife photographer Nicolas Reusens spent hours crouched in a cave in Costa Rica, often up to his knees in water, to take this photo of a jumping frog

Crayfish Turn Blood Cells into Brain Cells
by Christie Lepisto
… Scientists (have been) studying crayfish, which continuously regenerate neurons in their sensitive smelling organs and exposed eyestalks. Studying the process, known as neurogenesis, in crayfish could help us understand how humans maintain their brain health, and where the process goes wrong.
Scientists found that crayfish have a natural circuit for harboring blood cells similar to our white blood cells in a ‘nursery’ where they are turned into neurons. The cells are converted to have properties of stem cells, which allows them to be reprogrammed to become neurons.
What surprised scientists in this discovery is the link between the immune system and the regeneration of neurons. The blood cells converted to neurons in crayfish, called hemocytes, are produced by the immune system, in a process that parallels the production of white blood cells that are the front-line troops of the human immune system. In the words of co-auther Dr. Irene Söderhäll, of Uppsala University in Sweden..
