Jim Denevan
“The huge complex designs he carves into sandy beaches are out of this world. Jim Denevan makes freehand drawings in sand. At low tide on wide beaches Jim searches the shore for a wave tossed stick. After finding a good stick and composing himself in the near and far environment Jim draws, laboring up to 7 hours and walking as many as 30 miles.”
Imagine blowing through a straw into a nearly empty glass—we probably all did this as children and sent water, milk, and soda flying everywhere! In essence, this video shows that same act, but filmed by a high-speed camera. The “straw” blows a steady stream of helium into a shallow pool of silicone oil and slowly moves so that the angle the straw makes with the pool changes. As the angle changes, different regimes are visible. First waves appear on the surface of the pool, then a bulge forms, which develops into a droplet stream, then on into the chaos of bubbles and jets. It’s good I couldn’t see this in slow motion as a child or I would have never used my straw for drinking!

I assume it works…Mobius gear
From Wiki introduction to Möbius strip:The Möbius strip or Möbius band (…) is a surface with only one side and only one boundary component. The Möbius strip has the mathematical property of being non-orientable. It can be realized as a ruled surface. It was discovered independently by the German mathematicians August Ferdinand Möbius and Johann Benedict Listing in 1858.(Neatorama)

Meteor night by Hiroaki Koga
Trapped in a tiny perfect sphere of water, this unlucky ant is unable to escape. A sudden downpour gave it no time to take cover, and photographer Adam Gormley was there to snap the image. Adam, from Noosaville, Queensland, Australia, had been photographing spiders in his neighbour’s garden when the rain came down. He had no idea there was an ant in one of the three millimetre droplets until he viewed the images later. He said: “I thought it was some dirt inside the drop, and it was not my main focus, I liked the way the drop was sitting on the aloe-vera leaf, with the tiny hairs. When I uploaded the shot to my PC, I viewed it large, and I think I shouted out loud in excitement when I realised what I’d captured by accident!”

Tracking down the crafty neutrino
“It is very difficult to catch neutrinos, despite the fact that they are the commonest elementary particles in the universe. They may even have served as building blocks for all the matter that surrounds us. But they are nevertheless almost undetectable: in just one second several tens of billions of neutrinos pass through every square centimetre of our bodies without us ever noticing.”

Trees cocooned in spiders webs, an unexpected side effect of the flooding in Sindh, Pakistan
An unexpected side-effect of the flooding in parts of Pakistan has been that millions of spiders climbed up into the trees to escape the rising flood waters.
Because of the scale of the flooding and the fact that the water has taken so long to recede, many trees have become cocooned in spiders webs. People in this part of Sindh have never seen this phenomenon before - but they also report that there are now less mosquitoes than they would expect, given the amount of stagnant, standing water that is around.
It is thought that the mosquitoes are getting caught in the spiders web thus reducing the risk of malaria, which would be one blessing for the people of Sindh, facing so many other hardships after the floods.
