Silent Goodbye a sad reality. (Mom passes on & leaves small Children)

-
The quiet community of Ngodini, just outside Nelspruit in Mpumalanga, South Africa, woke up to heartbreaking news that left neighbours and relatives in disbelief. Twelve-year-old Ayanda had always been the responsible one. As the eldest of three children, she helped her mother care for her younger siblings, eight-year-old Sipho and four-year-old Amahle. Their mother, Nomsa, worked hard to provide for them, often reminding her children that no matter how difficult life became, they should always love and protect one another. One cold winter morning, the children woke up as usual. Ayanda prepared breakfast while waiting for their mother to get up for work. Minutes turned into an hour, but Nomsa never came out of her bedroom. Ayanda gently knocked on the door. "Mama?" she called softly. There was no answer. She knocked again, louder this time. "Mama, it's morning. You have to wake up." Still, there was only silence. Growing worried, Ayanda tried opening the door. H...

Nuclear scientists hail US fusion breakthrough

 Nuclear scientists using lasers the size of three football fields say they generated a huge amount of energy from fusion

Nuclear scientists using lasers the size of three football fields say they generated a huge amount of energy from fusion.

Nuclear scientists using lasers the size of three football fields said Tuesday they had generated a huge amount of energy from fusion, possibly offering hope for the development of a new clean energy source.

Experts focused their giant array of almost 200 laser beams onto a tiny spot to create a mega blast of energy—eight times more than they had ever done in the past.

Although the energy only lasted for a very short time—just 100 trillionths of a second—it took scientists closer to the holy grail of fusion ignition, the moment when they are creating more energy than they are using.

"This result is a historic advance for inertial confinement fusion research," said Kim Budil, the director of Lawrence Livermore National Laboratory, which operates the National Ignition Facility in California, where the experiment took place this month.

Nuclear fusion is considered by some scientists to be a potential energy of the future, particularly because it produces little waste and no greenhouse gases.

It differs from fission, a technique currently used in nuclear power plants, where the bonds of heavy atomic nuclei are broken to release energy.

In the fusion process, two light atomic nuclei are "married" to create a heavy one.

In this experiment scientists used two isotopes of hydrogen, giving rise to helium.

This is the process that is at work in stars, including our Sun.

"The NIF teams have done an extraordinary job," said Professor Steven Rose, co-director of the center for research in this field at Imperial College London.

"This is the most significant advance in inertial fusion since its beginning in 1972."

But, warned Jeremy Chittenden, co-director of the same center in London, making this a useable source of energy is not going to be easy.

"Turning this concept into a renewable source of electrical power will probably be a long process and will involve overcoming significant technical challenges," he said.

Picture: Karen Sandison/African News Agency(ANA) MultiChoice’s BEE scheme trying to find 22 000 shareholders who are missing out on millions By Edward West   Feb 16, 2021 CAPE TOWN - PHUTUMA Nathi, the MultiChoice black economic empowerment scheme of more than 80 000 shareholders, is looking for about 22 000 shareholders who owned shares and did not receive dividends of R207 million between 2006 and 2020. “This money belongs to our shareholders. We’re calling on them to contact us to get their money. In these tough economic times we want to do everything in our power to give them what is rightfully theirs,” Phuthuma Nathi chairperson Mandla Langa said in a statement yesterday. Phuthuma Nathi has been paying dividends every year since the start of the scheme in 2006. Am...

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....
