The puffer fish is, as the narrator describes, "dull, almost to the point of invisibility. But to compensate, he is probably nature's greatest artist."
He can't flash shiny fins to attract passing females, so, instead he creates incredibly detailed artwork in the sand through the careful and methodical strokes of his fins. It takes him a week of working nonstop while battling the current, but the precision of the resulting design is nothing short of astounding.

Brainy Octopus and its Coconut
The footage, shot by a diver in Lembeh, Indonesia April 2015, shows the a small octopus, known as the ‘coconut octopus’ because of its habit of using coconuts and shells to protect itself. It’s found on sandy bottoms in bays or lagoons in tropical waters of the western Pacific Ocean.
More and more research is revealing that humans aren’t the only animals that use tools – chimpanzees, dolphins, and crows – use tools as well. But what about an octopus? Is the coconut octopus using tools? Some scientists say yes.
Researchers from the Melbourne Museum in Australia claimed the coconut octopus uses tools for concealment and defense by gathering available debris to create a defensive fortress. The researchers filmed octopuses collecting coconut half-shells discarded by humans from the sea floor. The octopuses carried the shells for up to 20 meters (66 ft) and arranged them around the body to form a hiding place.

How flocking birds move in unison:
  • Bottom line: According to Wayne Potts, a zoologist who published in the journal Nature in 1984, birds in flocks are able to change direction quickly not just because they are following a leader, or their neighbors, but because they see a movement far down the line and anticipate what to do next. Potts called this the chorus-line hypothesis for bird movement.

Here are some podcasts that you can check out if you see a topic that looks interesting to you. I suggest you try taking a break from the hectic, multi-tasking, over-stimulating world we live in and sit back, close your eyes and just listen to one of the podcasts below. It will be a bit like going back before TV, to the years of the radio, when a person's mind painted the pictures of the faces and the scenes to accompany the voices they heard and the stories that were told... except for the fact that these are all about science.

  • June 1, 2015 Something a little different – ever been in water that sparkles and glows? For the past week, some beaches in southern Tasmania have been illuminating this awesome blue; thanks to noctiluca scintillans, a bioluminescent phytoplankton! Yep, the color and light is 100% natural. Pretty neat, eh! Commonly referred to as ‘sea sparkles’, it’s exactly as that name suggests: stir up the water, or watch the waves, and the water glistens, glows and absolutely sparkles!
And don’t miss the video below, also by Paul Fleming, captured as he walked through the bioluminescent waves.

During a recent expedition to the Gulf of California scientists from MBARI discovered a new field of hydrothermal vents, the deepest yet discovered in the Gulf of California. These new hydrothermal vent fields were found over thirty-eight hundred meters below the surface in the Pescadero Basin, located off the east coast of Mexico’s Baja California, about one hundred miles east of La Paz. These hydrothermal vents result from a unique combination of geology and chemistry. Using a remotely operated vehicle, researchers found towering white columns emitting geysers of clear shimmering liquid with temperatures up to 290 degrees Celsius. The superheated water flowing from these vents starts deep underground. As the hot water rises, it flows through and reacts with the surrounding bedrock, becoming saturated with carbonate minerals, which build up over time to form the large chimneys that were observed.

The solar system to scale. Interesting video about creating a model of our solar system that is actually to scale. How cool a feat is that? It requires 7 miles of uninterrupted space to pull it off!

This gorgeous timelapse was created by Jack Fusco. He calls it Wonder Endlessly. Jack said:

The title is a reflection of the desire to always seek new adventures. There are few things that can match the overwhelming sense of wonder felt when you’re looking up at a sky full of stars. Keeping that strong sense of wonder is what makes me want to head in to the middle of nowhere in the dark, to climb across wet rocks and dodge waves to capture something new.
How did he create it? Jack said:
  • "Hours of scouting and planning went in to each of the 26 different sequences in the video. Some were planned months in advance to coordinate the tide with right moon phase."

Rare superbloom in California’s Death valley

Parts of California’s Death Valley, the driest place in North America, are blanketed in wildflowers of yellow, purple, pink and white, a so-called “superbloom” not seen since 2005.
Death Valley is the hottest place on Earth and the driest place in North America, averaging about 5 centimeters (2 inches) of rain per year. Summer temperatures in the valley, which contains the lowest point in the United States, can reach 49 degrees Celsius (120 degrees Fahrenheit). Most of the time, the landscape is stark – salt flats, sand dunes and rocky mountains with a few hardy shrubs and small trees.

This year’s profusion of colorful flowers happened due to a perfect combination of autumn rains, warm temperatures and reduced winds. This year’s intense El Niño has also brought more rain than usual to the valley. El Nino can affect Death Valley by shifting the track of winter and spring storms into the area. Previous superblooms of 1998 and 2005 also happened occurred in El Nino years.

A Mercury Transit Music Video from SDO

Explanation: What's that small black dot moving across the Sun? Mercury. Possibly the clearest view of Mercury crossing in front of the Sun earlier this week was from Earth orbit. The Solar Dynamics Observatory obtained an uninterrupted vista recording it not only in optical light but also in bands of ultraviolet light. Featured here is a composite movie of the crossing set to music. Although the event might prove successful scientifically for better determining components of Mercury' ultra-thin atmosphere, the event surely proved successful culturally by involving people throughout the world in observing a rare astronomical phenomenon. Many spectacular images of this Mercury transit from around (and above) the globe are being proudlydisplayed.

ISS and Mercury Too

Explanation: Transits of Mercury are relatively rare. Monday's leisurely 7.5 hour long event was only the 2nd of 14 Mercury transits in the 21st century. If you're willing to travel, transits of the International Space Station can be more frequent though, and much quicker. This sharp video frame compositewas taken from a well-chosen location in Philadelphia, USA. It follows the space station, moving from upper right to lower left, as it crossed the Sun's disk in 0.6 seconds. Mercury too is included as the small, round, almost stationary silhouette just below center. In apparent size, the International Space Station looms larger from low Earth orbit, about 450 kilometers from Philadelphia. Mercury was about 84 million kilometers away. (Editor's note: The stunning video includes another double transit, Mercury and a Pilatus PC12 aircraft. Even quicker than the ISS to cross the Sun, the aircraft was about 1 kilometer away.)
