Human Genome on a ‘memory crystal’ that will lasts billions of years

In case of extinction, scientists have stored a copy of the human genome on a ‘memory crystal’!

Memory Crystal Of Humans Genome

The 360 terabyte data crystal will remain stable at room temperature for 300 quintillion years—a lifespan that only drops down to 13.8 billion years (i.e., the universe’s current age) if heated to 374 degrees Fahrenheit. Throw in the ability to survive both higher and lower temperatures, direct impact forces up to 10 tons per square centimeter, as well as lengthy exposure to cosmic radiation, and it’s easy to see how it is still the Guinness World Record holder for the most durable digital storage medium.

Vincent Van Gogh's The Starry Nights Turbulent Flow

‘The Starry Night’ and turbulence theories The atmospheric motion of the painted sky cannot be directly measured, so Huang and his colleagues precisely measured the brushstrokes and compared the size of the brushstrokes to the mathematical scales expected from turbulence theories. To gauge physical movement, they used the relative brightness or luminance of the varying paint colors.

They discovered that the sizes of the 14 whirls or eddies in “The Starry Night,” and their relative distance and intensity, follow a physical law that governs fluid dynamics known as Kolmogorov’s theory of turbulence. In the 1940s, Soviet mathematician Andrey Kolmogorov described a mathematical relationship between the fluctuations in a flow’s speed and the rate at which its energy dissipates.

The researchers studied the brushstrokes made by van Gogh, who painted the work after admitting himself to an asylum in southern France. PHOTO

On display at the Museum of Modern Art in New York, “The Starry Night” is an enormously popular work of art that has been recreated in Lego bricks, drones and dominoes. Huang said that scientists had long struggled to describe turbulent flow in fluid dynamics in a way that would allow them to predict the phenomenon and that a complete explanation remains a prevailing mystery of physics.

Earths Moon Gets A Mini Me Moon

For nearly two months this year, Earth’s moon will have company — a second moon. Technically, it isn’t a second moon, but rather an asteroid from the Arjuna asteroid belt — named 2024 PT5 — that will be caught in the Earth’s gravitational pull, according to a study in the journal Research Notes of the American Astronomical Society. This is how many “mini-moons” are formed. An object in space can get caught in the Earth’s gravitational pull, make a full rotation around the planet and be classified as an orbiter — or be labeled a flyby if it doesn’t make a full rotation around the Earth, which is what 2024 PT5 is doing. 2024 PT5, discovered on Aug. 7, is following a horseshoe-shaped path, which means that it will make a semi-orbit of the Earth and then return to its normal sun-centered orbit. Researchers said the mini-moon will take place from Sept. 29 until Nov. 25.

Blackhole Plasma JETS Longest Ever Seen

Scientists have discovered the longest pair of jets streaming from a black hole in a distant galaxy.

The jets shooting hot plasma are the largest ever spotted – about as long as 140 Milky Way galaxies lined up end-to-end.

JET Haute Victorian Era Stones

Beautiful Wood turns to Stone!

Jet, a flat-black, opaque gemstone derived from wood that has experienced extreme compression over millions of years, was the haute stone throughout the Victorian era, a time when fashion and jewelry deftly signaled a person’s social status, financial wealth and even emotional state.

Radiant diamonds, sapphires, and rubies have been among the most coveted gemstones on the planet for nearly a century. But long before their reign, a far less dazzling gem captured the hearts of jewelry lovers — and now it’s making a comeback.

Jacqueline Cullen, whose work is produced in ateliers in London and Whitby, was one of the first fine fashion jewelry designers to use Whitby jet, roughly 20 years ago. Her “Dark Matter” collection ushered jet into the future: Rounded forms carved from hunks of Whitby jet are set with black diamonds, resulting in jewels that affect little galaxies flickering with dim, tonal sparkle.
