12 October 12:24:29 Happy Throwback Thursday! This fish sure got the short end of the looks stick. Say hello to Lophius piscatorius, otherwise known as an angler fish. Native to the coastal waters of the northeast Atlantic, the Black Sea and the Mediterranean Sea, this unfortunate looking fish is made up mostly of a big ol’ head with a body that seems to be a bit of an evolutionary afterthought. It has long teeth that are pointed inward, making it easy for prey to swim in, but impossible to swim out. This scaleless fish also has pectoral fins that are utilized like feet, allowing it to “walk” along the ocean floor and camouflage itself in order to catch prey. Like what you see here on @Science?

10 October 19:42:12 Lava is a mixture of molten or semi-molten rock, volatiles, and solids that are found beneath the earth. Most magmas are in the range of 700 degrees to 1300 degrees CELSIUS 😏. During a volcanic eruption, the magma that leaves the underground is called lava and hardens quickly once exposed. Magma is generated within Earth’s mantle, the thick layer between Earth’s crust and outer core. The effect you are seeing here is caused by plate tectonics and was filmed by @pagefilms at the Kilauea volcano in Hawaii. They have an entire film available on Vimeo if you want to see more in HD.
10 October 01:42:30 This is a space shuttle tile that has been heated to 2200 degrees Fahrenheit. It can be held with your bare hands because of thermal conductivity. The tile may be hot, (really hot), but because it isn’t very conductive, it won’t transfer that heat fast enough to burn you. To illustrate this concept, picture a roast in your oven. You would easily touch the 350 degree food in your oven but touch the metal and 🔥🔥🔥. The metal in this case is far more conductive than the food. Cc: [reddit user: ChazDoge]
07 October 12:22:46 This unique rock formation of columnar basalt is known as Devils Postpile, and is located in eastern California near Mammoth Mountain within the Ansel Adams Wilderness. In the early 1900s, John Muir and other influential Californians persuaded the federal government to protect the site (due to the unique geology in the area) when a proposal to build a hydroelectric dam called for its demolition. Thankfully, they were successful, and the area now known as Devils Postpile National Monument received federal protection in 1911. Devils Postpile got its start much earlier, though. Roughly 80,000 to 100,000 years ago, hot basaltic lava began filling the Reds Meadow Valley north of the Monument. Basalt lava has a lower viscosity than other types of lava, allowing it to flow much more quickly. So, a river of lava flowed down the valley until it reached a natural blockage. The hot lava rich in iron and magnesium began to pool, forming a lava lake up to 120 meters deep. As the lava lake cooled (somewhat uniformly), contraction stresses developed because solid basalt has a lesser volume than its liquid form. To release the internal stress created by cooling and contraction, a ‘cracking’ process called “jointing” occurred. At Devils Postpile, jointing formed the hexagonal columns for which the location is now famous.

03 October 20:27:03 🐍✨ This is Epicrates cenchria, also known as the rainbow boa. This species can be found in Central and South America, although their vibrant coloration has made them a popular pet across the globe. These boas owe the majority of their fame to the mesmerizing iridescent sheen they exhibit due to structural coloration, which refers to the production of color by microscopically structured surfaces fine enough to interfere with visible light. As scientists Stéphanie Doucet and Melissa Meadows (2009) detail in their report on the topic, iridescence is the result of the interaction of light with biological tissues that are nanostructured to produce thin films or diffraction gratings. In the case of the rainbow boa, iridescence is generated by structures called ‘iridophores,’ tiny crystal-like cells that affect visible light. These iridophores diffract light, resulting in the ‘rainbow’ effect we see when looking at these beautiful creatures. What’s your favorite iridescent animal?

19 September 11:55:11 Meet the storm glass weather forecaster. 🤓 Containing a mixture of distilled water and camphor, the 19th century Europeans used weather predicting devices like this one as a tool to aid them in navigation. The liquid inside changes in appearance based on forthcoming weather conditions and is surprisingly accurate. During our testing, it predicted the weather accurately 4 out of 5 times, which is more than we can say for most weather stations. If you want one of your own to try out, they re absolutely stunning and surprisingly cheap. We ve found them for $24.99 and put a link in our bio for you to get one.
14 September 15:32:08 You may have come across this dazzling fish before. Native to the Pacific, the mandarinfish (Synchiropus splendidus) is popular in the saltwater aquarium trade, and has been displayed in aquariums across the globe. The mandarinfish is most famous for its vibrant coloration, which is not only beautiful, but also quite interesting. The fish is one of only two vertebrate species known to have blue coloring due to cellular pigment. Scientists Makoto Goda and Ryozo Fujii of the Zoological Society of Japan found dendritic chromatophores that contain blue pigmentary organelles in the bluish parts of the skin of the fish. They named these special pigment-containing and light-reflecting cells “cyanophores” and the organelles “cyanosomes.” The researchers found that the cyanophores respond to stimulatory cues by aggregating or dispersing cyanosomes. In most other cases of blue coloring, the color blue is structural, coming from thin-film interference from piles of purine crystals.

29 August 15:52:58 This image was released by the U.S. National Oceanic and Atmospheric Administration and shows Tropical Storm Harvey approaching Texas from the Gulf of Mexico. The picture was taken on the morning of August 24th by GOES-16, the most advanced weather satellite NOAA has ever developed. Harvey, a tropical cyclone, breached the coast of Texas late Friday, August 25th, bringing with it unprecedented levels of rainfall and catastrophic flooding. By some estimates, the affected areas are expected to see a year’s worth of rainfall in the course of a week. The situation is already dire, with thousands of people needing rescue in the Houston area alone due to a record-breaking 75 cm of rainfall so far. Officials anticipate the number of victims to continue to rise throughout the week, with potentially half a million people needing assistance in Texas and Louisiana. The U.S. National Weather Service expects flooding to worsen through Thursday, August 31st.
