The House She Built a Source of Conflict

-
There was a time when everything seemed to be going right for Amara . She was a beautiful woman, not only in appearance but in the way she carried herself. She grew up in a loving home, surrounded by parents who worked hard and believed that their children should never lack opportunities. Her father was a respected man who worked tirelessly to provide for the family, while her mother was equally hardworking. They raised their daughters with discipline, kindness, and the belief that education and hard work were the keys to a good life. Amara was the elder daughter. Her younger sister, Nadia , was also intelligent and ambitious. The two sisters grew up watching their parents work together, and they learned an important lesson from them: nothing worthwhile comes without sacrifice. As the years passed, both sisters became successful in their own ways. Amara worked hard, saved her money, and eventually achieved something she had dreamed about since she was young. She bought a beauti...

A diamond bigger than Earth

LONDON (Reuters) - Forget the diamond as big as the Ritz. This one's bigger than planet Earth.
Orbiting a star that is visible to the naked eye, astronomers have discovered a planet twice the size of our own made largely out of diamond.
The rocky planet, called '55 Cancri e', orbits a sun-like star in the constellation of Cancer and is moving so fast that a year there lasts a mere 18 hours.
Discovered by a U.S.-Franco research team, its radius is twice that of Earth's with a mass eight times greater. That would give it the same density as Earth, although previously observed diamond planets are reckoned to be a lot more dense. It is also incredibly hot, with temperatures on its surface reaching 3,900 degrees Fahrenheit (1,648 Celsius).
"The surface of this planet is likely covered in graphite and diamond rather than water and granite," said Nikku Madhusudhan, the Yale researcher whose findings are due to be published in the journal Astrophysical Journal Letters.
The study - with Olivier Mousis at the Institut de Recherche en Astrophysique et Planetologie in Toulouse, France - estimates that at least a third of the planet's mass, the equivalent of about three Earth masses, could be diamond.
Diamond planets have been spotted before but this is the first time one has been seen orbiting a sun-like star and studied in such detail.
"This is our first glimpse of a rocky world with a fundamentally different chemistry from Earth," Madhusudhan said, adding that the discovery of the carbon-rich planet meant distant rocky planets could no longer be assumed to have chemical constituents, interiors, atmospheres, or biologies similar to Earth.
David Spergel, an astronomer at Princeton University, said it was relatively simple to work out the basic structure and history of a star once you know its mass and age.
"Planets are much more complex. This 'diamond-rich super-Earth' is likely just one example of the rich sets of discoveries that await us as we begin to explore planets around nearby stars."
"Nearby" is a relative concept in astronomy. Any fortune-hunter not dissuaded by "The Diamond as Big as the Ritz", F.Scott Fitzgerald's jazz age morality tale of thwarted greed, will find Cancri e about 40 light years, or 230 trillion miles, from Park Avenue.

This New Ultralight Aircraft May Be World’s Fastest Single-Engine Business Jet

  The speedy LAR-01's automotive interior adds comfort and luxury. Plus: The wings detach, so the jet can be stored in a home garage. By  MICHAEL VERDON           Courtesy Flaris The  Flaris  LAR-01 has a number of striking stats, including being a ton lighter (literally) than its competitors, along with an unusually short-field landing capability, and detachable wings. But its most impressive number is the 250-knot true air speed, which its designers say makes it the world’s fastest business jet among single-engine very light jets and turboprop aircraft. Flaris says recent tests “confirmed the assumptions made previously” about the effectiveness of multiple systems, including its Garmin G600 avionics and Flaris Flight Assistance System flight computer, as well as the landing gear and emergency parachute system. But it also claims more impressive stats like the 250-knot TSA at 10,000 feet. Its 6,000-feet-per-minute climb rate, adds the compan...

Fighting Drug addiction

-
 Here's the story: We sat down with a man who had a harrowing journey with addiction. He began by telling us about his early days in tertiary education, where he would occasionally smoke dagga with friends. However, his focus remained on his studies, and he worked hard to graduate and secure a qualification. After landing a job, he started building a life for himself. He got married, bought a property, and even splurged on a car. Life was good, and he felt like he was on top of the world. But one fateful night, while out with friends, he was introduced to heavier narcotics. At first, the experience was exhilarating. He described it as an elevation from the mild high of dagga to a level 5 high, where he felt invincible and euphoric. The effects would last for days, allowing him to party from Friday to Sunday without sleep. The problem, however, began to manifest on Mondays and Tuesdays every week, when the withdrawal symptoms would kick in, and he'd struggle to function at work....

Ultra-Widebody Volkswagen Bus "Volkswide" Looks Like a Porsche Racing Van

  Home   >   News   >   Renderings It's easy to understand why a muscle car or a Ferrari is cool - the big engine and cool body. But car culture is also influenced by television, rarity, or simply a generation growing up with a particular vehicle. The Volkswagen Bus is a perfect example of this because it's slow, not sporty-looking, yet it can cost a lot of money.  16 photos The Bus is perhaps one of the least understood collectibles, right up there with bubble cars. You see them grabbing huge money at auctions, making it difficult to visualize why somebody wouldn't rather have a Ferrari or some 1960s Mustang. Comedian Gabriel Iglesias is known as the VW Bus King, as his collection of Vdubs is reportedly worth in excess of $3 million. The Hoonigan crew recently did a feature video, but we still had trouble picturing the value of these vehicles. Fortunately, there's a set of renderings that takes the visuals of the Microbus to the level where everybody...
