Quick rundown on menopause Things that we ignore

-
 1. What it is Menopause is diagnosed after 12 consecutive months without a period. The average age in most countries is around 45–55, but it varies.  2. Key phases   Perimenopause: The transition period before menopause, often 4–8 years. Hormones fluctuate, cycles become irregular.   Menopause: The point when ovaries stop releasing eggs and estrogen/progesterone drop.   Postmenopause: The years after menopause. Symptoms often ease, but health risks like osteoporosis and heart disease increase. 3. Common symptoms   Hot flashes + night sweats Irregular periods → then no periods Sleep problems Mood changes, anxiety, or depression   Vaginal dryness, lower libido Bone density loss, joint pain 4. Why it matters for workforce diversity In companies like Amber Distributors, menopause affects women typically in their late 40s to 50s. If your workforce is predominantly male and older, you might miss how menopause impacts productivity, a...

The melting of ice from glaciers and landmasses such as Greenland and Antarctica is causing the Earth’s crust to warp slightly, a new study suggests.

As ice sheets and glaciers melt across the globe and water is redistributed to global oceans, the Earth’s crust is liberated from the overlying weight and lifts up, said the research published in the journal Geophysical Research Letters last week.

This melting could generate a complex pattern of three-dimensional (3D) motions at the Earth’s surface, even in places over 1,000 kilometres away from the ice loss, according to the scientists behind the study, including Sophie Coulson from Harvard University in the US.

“This 3D surface motion is on average several tenths of a millimetRE per year, and it varies significantly year to year,” the study noted.

In the research, scientists used satellite-derived data on early 21st century ice loss from Greenland, Antarctica, mountain glaciers and ice caps, to predict how the Earth’s crust deforms with changes in its mass.

Between 2003 and 2018, ice melting from Greenland and the Arctic glaciers have “caused the ground to shift horizontally” across much of the Northern Hemisphere, changing by as much as 0.3 millimetres (mm) a year in large parts of Canada and the US, said researchers.

“We show that, rather than only being localised to regions of ice loss, melting of the Greenland Ice Sheet and Arctic glaciers has caused significant horizontal and vertical deformation of the crust that extends over much of the Northern Hemisphere,” the scientists wrote in the study.

The study predicted a crust deformation of 0.05–0.3 mm per year in most parts of Canada and the US, with a deformation of 0.05–0.2 mm per year in Europe, including parts of Fennoscandia, which constitutes Finland, Norway and Sweden.

Climate researchers call for future work to further assess crustal warping due to ice melting to improve both horizontal and vertical measurements made by navigational satellite systems.

  USINESS REPORT COMPANIES MultiChoice’s black economic empowerment scheme is looking for about 22 000 shareholders who owned shares and did not receive dividends of R207 million between 2006 and 2020. 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...

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....

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...
