Comments Off on These diamonds from outer space hint at a long-lost planet

Diamonds in a meteorite  that crashed into Earth years ago have now given scientists a glimpse into the universe’s past. Recently, a team of scientists led by the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Switzerland used transmission electron microscopy to examine the diamonds contained in a slice of the Almahata Sitta meteorite. Based on their research, the scientists think the meteorite came from a planetary embryo, between the size of Mercury and Mars , that was destroyed in a collision around 4.5 billion years ago. Nearly a decade ago, an asteroid exploded over the Nubian Desert in Sudan. Scientists collected fragments from what’s now called the Almahata Sitta meteorite, and these fragments have yielded intriguing new information. EPFL materials scientist Farhang Nabiei told The Washington Post , “These samples are coming from an era that we don’t have any access to…This is part of the story of how we came to be.” The meteorite fragments are largely ureilites, which EPFL said are “a rare type of stony meteorite” in which nano-sized diamonds can be found. Related: New theory suggests the Moon may have formed “from a giant donut of vaporized rock” Embedded in the diamonds were chromite, phosphate, and iron-nickel sulfides; the scientists call these inclusions, and they hold signatures of the mysterious long-lost planet . According to EPFL, the “particular composition and morphology of these materials can only be explained if the pressure under which the diamonds were formed was higher than 20 GPa (giga-Pascals, the unit of pressure). This level of internal pressure can only be explained if the planetary parent body was a Mercury- to Mars-sized planetary embryo, depending on the layer in which the diamonds were formed.” What exactly happened to the long-lost planet? Nabiei couldn’t say for sure. Researchers think that, in the early solar system , large protoplanets pulled on others’ orbits until they coalesced, crashed, or broke up into pieces. The ureilites could have come from the same protoplanet that existed for a few million years before its demise in a collision.

Rare "super-deep" diamond and mineral found in South African mine

Comments Off on Rare "super-deep" diamond and mineral found in South African mine

Scientists have uncovered a rare “super-deep” diamond in the Cullinan mine in South Africa’s Gauteng province. Wrapped in this diamond is the mineral calcium silicate perovskite, the fourth-most abundant mineral found on Earth — a significant discovery because, despite its abundance, this marks the first time in which calcium silicate perovskite has been found in nature. “This was very special because this mineral had been theoretically predicted, but it was not thought possible to see it preserved at the Earth’s surface for observation and measurement,” study co-author Graham Pearson told Inverse . “Finding a natural object that has never been seen by anyone before is always exhilarating! It’s what most natural scientists dream about.” Cullinan Mine is known for its rare blue diamonds as well as its scientific and commercial value. According to the authors of the study published in Nature , diamonds “provide access to the deepest intact material from the Earth’s interior through the minerals contained within their volumes.” The discovered diamond is called “super-deep” in reference to its origins 200 to 1,000 kilometers (about 125-621 miles) below the surface of the Earth , The first-ever natural discovery of calcium silicate perovskite (CaSiO3) wrapped in a rare diamond is providing scientists with a privileged glimpse into the deep inner workings of the Earth. Related: Scientists observe ‘diamond rain’ similar to that found on icy giant planets The super-deep diamond was determined to have formed approximately 760 kilometers below the surface of the Earth. Because the diamond formed in such a deep location, it was highly pressurized. This enabled the diamond to successfully hold CaSiO3, which exists only in very high pressure environments. “Only the super-strong nature of the diamond, and the particular nature of the fast eruption of the host kimberlite, in this case, provided a favorable set of circumstances that led to the preservation of this mineral ,” explained Pearson. “Many people predicted that we would never actually see a natural version of this mineral at the Earth’s surface because it is so unstable.” Via Inverse Images via Wikimedia and Petra Diamonds

Comments Off on Nature-inspired concert hall in Texas invokes the spirit of Buddy Holly

Though legendary Rock and Roll Hall of Famer and 1950s pop star Buddy Holly was tragically killed in a plane crash at only 22, he left an influential legacy. The $125 million, privately funded Buddy Holly Hall of Performing Arts dedicated in his honor will comprise a 2,200-seat main theatre , an additional 400-seat theater, a 5,000-square-foot multipurpose room, and a 22,000-square-foot dance center. The project will also spearhead downtown revitalization of Lubbock and the South Plains. The surrounding Llano Estacado plains and the local conditions “heavily shaped” the design of the building, said Diamond Schmitt principal Matthew Lella. “The fenestration has allowed long, horizontal views to the landscape to capture the beauty of the sky, which seems to go on forever and is continuously changing colour and mood. The long shallow slope on the main roof at the entrance is inspired by the angle of repose of the local soil.” Related: New Mexico Highlands University Student Centre Responds to Desert Climate with a Sun-Tracking Louvered Facade The earthy materials palette was selected to blend the building into the environment, while carefully designed overhangs protect the building from solar gain and provide shade. A dynamic light sculpture wrapped around a 200-foot-tall telecommunications tower anchors one side of the site and will serve as a symbol for the venue and of renewal for Lubbock. Construction of the concert hall is expected to begin this fall. + Diamond Schmitt Architects Via Dezeen Images via Diamond Schmitt Architects

Brilliant diamond highway interchange eliminates dangerous lefthand turns

Comments Off on Brilliant diamond highway interchange eliminates dangerous lefthand turns

Just about every time we drive, we’re forced to make left turns, risking head-on or 90-degree collisions with cars coming from the opposite direction. An innovative new highway interchange significantly reduces this risk. Called a diverging diamond, this design allows drivers to avoid the hazardous turns altogether. https://www.youtube.com/watch?v=24jMVZszPTY Diverging diamond interchanges may appear complicated at first glance, but research reveals that drivers consistently navigate them with few issues. Roads cross each other so drivers on the right hand side of the road cross to the left and vice versa. Therefore, drivers on a diverging diamond interchange don’t have to turn against traffic when they go left; they simply merge away to the left. The roads cross again further down the street after left turns for both sides. Drivers entering the interchange simply merge left or right, and only have to worry about oncoming traffic from one direction instead of two. Related: Germany opens the first 3 miles of a 60-mile bicycle superhighway France constructed some diverging diamond highways in the 1970’s, but they didn’t really catch on in America until a graduate student named Gilbert Chlewicki wrote about the design in 2000 and realized his idea had already been implemented overseas. Nearly a decade later, diverging diamonds began to gain popularity as states such as Missouri and Utah adopted the concept. Wired reports that since 2009 , 22 states have built 62 of these innovative, safe roads. Research shows they work. University of Missouri engineers, along with colleagues around America, performed ” the first in-depth safety analyses ” in 2015. These are the stats: five out of seven intersections experienced ” serious safety improvements .” Deadly crashes occurring on terminal ramps declined by more than 60 percent. And crashes that do occur don’t result in death as often. The team estimated that crashes overall on the new safe roads are reduced by 33 percent. Via Wired Images via screenshot

It’s sort of cute how people in the world of finance consider themselves. Compared to the diamond-hard certainty of chemistry, biology and physics, the so-called "reality" of economics is about as substantial as tissue paper.
