Did Native Americans Originate from Japan?
The biological evidence "simply does not match up"
with archeological finds.
However, the authors of the new study say this scenario is highly unlikely because the biological evidence "simply does not match up" with the archaeological findings, according to a statement from the researchers.
Instead, the researchers suspect that Native Americans descended from a different group living somewhere in East Asia, although a lot of uncertainty remains about exactly where and when those ancestors lived.
"The artifact similarities between ancient Jomon and at least some of the earliest known Native American sites lie in the stemmed projectile points," co-author John Hoffecker, an archaeologist at the Institute of Arctic and Alpine Research at the University of Colorado Boulder, told Live Science. These similarities led previous researchers to suspect that the knowledge to make those tools had been passed down from one culture to the other, he added. READ MORE...
We Know Where to Look on Mars
"We're definitely in the right place."
There's an air of relief in the science team running the American space agency's (Nasa) Perseverance rover on Mars.
The researchers are sure now they've sent the robot to a location that provides the best possible opportunity to find signs of ancient life.
"Percy" touched down in Jezero Crater in February and ever since has been snapping thousands of images of its surroundings.
The interpretation of these pictures forms the basis of the first scholarly paper to make it into print, in this week's edition of Science Magazine.
The analysis confirms the rover is sitting on the floor of a once great lake that was fed by a meandering river entering the deep bowl from the west. We're talking of events over 3.5 billion years ago when the Red Planet's climate was far more benign.
From Perseverance's observations, it's now certain that where the river system met the lake water, the flows suddenly slowed and the sediment in suspension fell out to form a delta - the kind of wedge-shaped "landform" you'll see all over the Earth. READ MORE...

Earth Surrounded by Giant Tunnel
Mysterious structures in the sky that have puzzled astronomers for decades might finally have an explanation – and it's quite something.
The North Polar Spur and the Fan Region, on opposite sides of the sky, may be connected by a vast system of magnetized filaments. These form a structure resembling a tunnel that circles the Solar System, and many nearby stars besides.
"If we were to look up in the sky," said astronomer Jennifer West of the University of Toronto in Canada, "we would see this tunnel-like structure in just about every direction we looked – that is, if we had eyes that could see radio light."
We've known about the two structures for quite some time – since the 1960s, in fact – but they have been difficult to understand. That's because it's really hard to work out exactly how far away they are; distances have ranged from hundreds to thousands of light-years away.
However, no analysis had ever linked the two structures together. West and her colleagues were able to show that the two regions, and prominent radio loops in the space between them, could be linked, solving many of the puzzling problems associated with both.

West)"A few years ago, one of our co-authors, Tom Landecker, told me about a paper from 1965, from the early days of radio astronomy. Based on the crude data available at this time, the authors (Mathewson & Milne), speculated that these polarized radio signals could arise from our view of the Local Arm of the galaxy, from inside it," West explained.
"That paper inspired me to develop this idea and tie my model to the vastly better data that our telescopes give us today." READ MORE...

US Debt On Its Way UP...
The American debt is out of control, but America can afford it
because of the American dollar.
Image: Adobe StockThe US debt will reach $30T in the coming months. This is a certainty. While this seemed hardly imaginable only ten years ago when the US debt was still “only” $14.3T in 2011, it is now unavoidable as it reaches $28.8T at the time of writing.
In only ten years, the US debt has thus increased by +101%.
This would not be so serious if America’s GDP had grown at the same rate over this period. However, this is not the case, since the US GDP has stalled. Over the same period the US GDP grew by “only” +46.5%.
America Gross Domestic Product — Source: The FedUnder these conditions, it is not surprising that America’s debt-to-GDP ratio has risen well above 100% and currently stands at 127%. The time when having a debt-to-GDP ratio above 100% was taboo is over.
Among the world’s major economic powers, it has even become the norm.
The American debt is divided into two main categories
The US debt is managed by the US Treasury Department through the Bureau of Public Debt. The debt is divided into two broad categories: intra-governmental holdings and debt held by the public.
Intra-governmental debt is debt that the U.S. Treasury owes to other federal agencies. Some agencies, like the Social Security Trust Fund, collect more tax revenue than they need. Instead of putting this money under a giant mattress, these agencies invest in U.S. Treasury bonds.
Currently, this intra-governmental debt is about $6.4T. TO KNOW MORE ABOUT OUR DEBT... CLICK HERE...
Media Making Mistake
Jon Stewart says media making 'mistake' casting Trump as
'incredible supervillain'
'I think we make a mistake focusing this all on Donald Trump, as if he's ... some incredible supervillain that has changed the very nature and temperature of the US'
Comedian Jon Stewart said the media's hyperfocus on former President Trump is a mistake and that casting him as an "incredible supervillain" distracts from other threats.
The former "Daily Show" host told CNN's Jake Tapper in an interview airing Sunday that political pundits are "making a mistake" blaming Trump for the country's divisive discourse, arguing they should turn their focus to the threat posed by much larger institutions that have dangerously embraced "the idea that power is its own reward."
"I think we make a mistake focusing this all on Donald Trump, as if he's … Magneto and some incredible supervillain that has changed the very nature and temperature of the U.S.," Stewart said. "He's just been an effective vessel, but he's not singing new songs. … I think it's a mistake to focus it all on this one individual and not to focus it more on the idea that power is its own reward whether it be in the financial industry or government. Power doesn't cede itself, and unless we can figure out a better way to balance out that power … we'll be vulnerable." TO READ MORE ON STEWART"S THINKING, CLICK HERE...
What is VoIP?

What to look for in a VoIP provider
We've expanded this guide to take a closer look at what you need to know about Voice over Internet Protocol. We'll cover everything you need to know, including the benefits of VoIP phone service.
What is VoIP?
VoIP is an acronym for Voice over Internet Protocol that describes the method to place and receive phone calls over the internet. Most people consider VoIP the alternative to the local telephone company.
If you've heard of an IP address, that's your Internet Protocol address. An IP address is how computers and devices communicate with each other on the internet.
VoIP isn't actually all that new. Telephony has relied on digital lines to carry phone calls since the late 90s. VoIP is a cost-effective way to handle an unlimited number of calls.

Spain's Liquid Gold
For centuries, people have tapped pine trees to extract resin. But in one Spanish province, locals believe this age-old practice could save rural towns while also helping the planet.
Stretching north from Madrid, north-west Spain's autonomous Castilla y León region is a patchwork of vast mountain ranges, high plateaus and medieval towns. While most visitors come to marvel at the castillo castles that lend the region its name or admire the enchanting cathedrals in León and Burgos, much of the area is blanketed in scrubby sierra and high-altitude meseta plains that extend as far as the eye can see.
But in the provinces of Segovia, Ávila and Valladolid, a drastically different landscape emerges. Here, amid the Tierra de Pinares and Sierra de Gredos mountain ranges, a thick, 400,000-hectare protected forest of fragrant resin pines stretches up into the mountainous folds. Shielded from the hot Spanish sun and lined with trails and, this forested frontier is a popular hiking destination for locals and tourists. And, if you visit at the right time of year and look closely, you may see workers crouched next to the tree trunks, continuing a centuries-old tradition of collecting the pine's "liquid gold".

Pine resin has been used by different civilisations for thousands of years. In Spain and across much of the Mediterranean, it was used to waterproof ships, treat burns and light torches, among other things. But according to Alejandro Chozas, a professor in the forestry engineering department at Madrid Polytechnic University, it wasn't until the 19th and 20th Centuries that the extraction of pine resin became truly profitable in the Castilla y León region.
As technology and industrialisation helped turn the thick, milky sap into things like plastics, varnishes, glues, tyres, rubber, turpentine and even food additives in the mid-19th Century, the owners of Castilla y León's dense Pinus pinaster forests saw an opportunity. Soon, workers were hacking into the bark of resin pines across the region in order to collect the valuable sap. And while this time-consuming process has now ceased across much of the world, in the past decade it has experienced something of a rebirth in Castilla y León, which is home to more resin manufacturers than anywhere else in Europe and one of the last places on the continent where the practice persists.

African Tech Giant JUMIA
It could not have got off to a much better start for Jumia's historic stock market listing. The hoopla on the day it became the first Africa-focussed tech firm to list on the New York Stock Exchange was massive.
International media took note and investors piled in, its share price rose more than 70% in value on the day but the excitement would prove to be short-lived.
"In our countries where we operate there are 700 million people and last year we served more than four million consumers" co-chief executive officer Sacha Poignonnec told the BBC on the floor of the stock exchange.
When I sat down to speak with his co-CEO, Jeremy Hodara, in September the firm had had a humbling few years. Share prices plummeted and came back, backers had bailed out, and it had withdrawn from trading in three of the fourteen countries it was operating in - and that's not to mention reports of fraud lawsuits in New York courts and a public relations disaster over its identity.
But the promise of millions of consumers newly connected to the internet has not gone away and neither has interest in Jumia which is still by far the largest e-commerce company focussed on the African continent - although its management and much of technical expertise is based outside of Africa.

By 2030, consumer spending across Africa is expected to reach $2.5tn. Jumia still sells goods in 11 of those countries. It operates a marketplace where thousands of other businesses sell goods on its platform and has a finance arm, Jumia pay, so customers can go about their shopping, pay utility bills and order pizza, all without leaving the Jumia's platforms.
