There are large areas of the United States under Republican control where COVID-19 deaths and COVID-19-related deaths are openly undercounted. Unfortunately for the GOP and Trump death-cult followers, life insurance doesn’t care about your internet research degree at MAGA Meme University. Their entire business model is based on the gamble that they can figure out exactly who will die and when, based on the best actuarial science and statistical data available.

Comedian Greg Fitzsimmons once told a joke that the strange relationship a consumer has with life insurance can be summed up as the consumer placing a bunch of money on a table and saying, “I bet you I die this year,” and the insurance company picking up the money, counting it, and saying “We bet you don’t.”

Life insurance companies do not care about your feelings. People either die or they don’t. Different groups of people have higher mortality rates for a variety of reasons, and life insurance companies…

DNA in Unlikely Places Helps Piece Together Ancient Humans’ Family Trees

Excerpt:

 

One hundred thousand years ago, Neanderthals gathered in a cave perched 3,000 feet up in present-day Spain’s Atapuerca Mountains. While cooking and watching youngsters wrestle, they littered the floor with DNA in shed skin, spit and other bodily debris. 

Dirt accumulated and protected the genetic material for millennia, even as humans and animals sheltered there. At the site, known as Estatuas, archaeologists have uncovered abundant stone tools and animal bones since 2008. The sole Neanderthal bone found — a toe tip with Swiss cheese consistency — seemed too precious to crush for DNA analysis. The scientists therefore couldn’t elucidate the inhabitants’ genetic traits and ties with other Neanderthal clans.

Instead, they searched the dirt for loose DNA. In 2018, researchers dropped into pits at Estatuas and collected sediment from layers that formed between 70,000 and 113,000 years ago. They had fetched nearly 800 sediment samples in 2017 from the Chagyrskaya and Denisova caves in southern Siberia, promising locations that had already yielded DNA-bearing fossils of Neanderthals and their Denisovan relatives.

At the Max Planck Institute in Germany, Benjamin Vernot and colleagues separated the human DNA from sequences belonging to animals, plants and microbes. The resulting Science and Nature papers demonstrated that dirt devoid of fossils and artifacts can conceal a genetic treasure trove. At Denisova Cave, researchers extracted human DNA fragments from over 220 sediment samples — versus nine fossils with genetic material. The dirt indicated that lineages of Neanderthals, Denisovans or Homo sapiens lived there at different points.

Excerpt:

A key part of protecting endangered species is figuring out where they’re living. Now researchers say they have found a powerful new tool that could help: vacuuming DNA out of the air.

“This is a bit of a crazy idea,” admits Elizabeth Clare, a molecular ecologist at York University in Toronto, Canada. “We are literally sucking DNA out of the sky.”

But it works. Clare’s group was one of two to publish papers in the journal Current Biology Thursday showing that dozens of animal species could be detected by simply sampling the air.

Darkness caused by dino-killing asteroid snuffed out life on Earth in 9 months

From www.livescience.com
2021-12-22 15:57:07

Excerpt:

 

The years following the asteroid impact that wiped out non-avian dinosaurs were dark times — literally. Soot from raging wildfires filled the sky and blocked the sun, directly contributing to the wave of extinctions that followed, new research has found.

After the asteroid struck, around 66 million years ago, the cataclysm extinguished many forms of life instantly. But the impact also caused environmental changes leading to mass extinctions that played out over time. One such extinction trigger may have been the dense clouds of ash and particles that spewed into the atmosphere and spread over the planet, which would have enveloped parts of Earth in darkness that could have persisted for up to two years.

During that time photosynthesis would have failed, leading to ecosystem collapse. And even after sunlight returned, this decline could have persisted for decades more, according to research presented Dec. 16 at the annual meeting of the American Geophysical Union (AGU), held in…

Solar Winds Brought Water to Earth?

Solar winds blew dust onto the face of the earth, from which water was created.  This is the current theory emerging from a group of researchers out of the University of Glassgow.

Mystery surrounding origin of water on Earth solved by new research

Excerpt:

Researchers may have solved a mystery about the origins of Earth’s water, finding the Sun to be a surprising source.

The scientists describe how new analysis of an ancient asteroid suggests extra-terrestrial dust grains carried water to Earth as the planet formed.

According to the study, the water in the dust was produced by ‘space weathering’.

Researchers found the solar wind, made up of charged particles from the Sun, created water on the surface of dust grains carried on asteroids that smashed into the Earth during the early days of the Solar System.

Are We Pushing Girls Away from STEM?  One Study Says Yes

A study recently published in a medical journal suggests ‘gender-interest stereotypes’ contribute to a drop in the number of girls who might be interested in STEM by as much as 50 percent, a startling figure if true.

What’s not certain about the study is whether these gender-interest stereotypes emerged from a biological reality of whether they were imposed in an effort to hem in the dynamic of a particular group, in this case, the female of the species.   In other words, is it genes or is patriarchy?  It is probably a lot of both.

As a people, it is in all our interests for our girls to be given less expectations and more options, as well as our boys.  This study could potentially help us understand how to create more space for our children to discover more fully who they are, not who the world expects them to be, or it could become a cudgel used to beat on all things currently (allegedly) ‘orthodox’ and traditional.

My suspicion is if you apply the standard of creating space for boys and girls to discover more fully who they really are then the counter-coercive methodology of invalidating the orthodox and traditional and fetishizing anything the orthodox or the traditional is not would be a feckless tactic to try on such a people as that.

That respect of self becoming who they are by choice works to cut the orthodox and traditional from coercively stamping their assumptions on the next generations, but it also works to cut the non-orthodox and the non-traditional off from coercively stamping their assumptions on the next generation in a bid to become the NEW coercively imposed orthodoxy and tradition.

My suspicion is that a people raised in such liberties will produce remarkably similar ‘orthodox’ and ‘traditional’ patterns as before, just maybe not so overwhelmingly so, as the non-orthodox, the non-traditional are free to openly engage in all public space, respective of one another’s Bill of Rights ‘protections.’

The unity is the Bill of Rights, which makes the diversity possible.  A Bill of Rights constructed land, a Bill of Rights led people will be respecters of what our children choose to become, not coercive stampers of our assumptions onto their newly developing minds.

Just a caveat in closing, this is NOT to suggest I don’t believe we share our orthodoxies and traditions, nor that we don’t offer some boundaries to our children, and boundaries against the world in dealing with our kids in matters that belong between parent and child alone.

Gender stereotypes can drop girls’ interest in STEM by 50%

Even children as young as 6 can develop ideas that girls don’t like computer science and engineering as much as boys – stereotypes that carry over into teenagerhood and contribute to gender gaps at university, according to a study published in PNAS.

“Gender-interest stereotypes that STEM is for boys begins in grade school, and by the time they reach high school, many girls have made their decision not to pursue degrees in computer science and engineering because they feel they don’t belong,” says lead author Allison Master, of the University of Houston.

The study involved four different experiments to assess the beliefs of a racially diverse sample of children and teens right throughout school. Instead of exploring who children perceived as ‘good’ at STEM subjects, they investigated who children thought liked them, which can affect childrens’ sense of belonging and willingness to participate in STEM-related activities.

Chinese Silk Could Save Hot Summers

The Chinese are developing a new type of fabric  that can make humans feel 15 percent cooler when they put the clothes on in hot conditions.  The technology is sure to be duplicable by others, and, hopefully, will be duplicated by those committed to open source technology that gives all of humanity the opportunity to develop and exploit this type of technology.

With China working hard to colonize Africa, one can see how a product such as this could be a billions of yuan winfall for the CCP-controlled corporations that produce such products.  It would be better for Africa to develop their own engineered silk products and produce them in-continent than to pin such a dependence to such a totalitarian and supremacist state as China.

Fabric technology: Modified silk keeps skin 12°C cooler than cotton

Climate change is making summer days even hotter for some – but new clothing might helps us keep cool

A fabric made of engineered silk keeps skin about 12.5°C cooler than cotton clothing and provides relief from hot weather.

Approximately 15 per cent of global electricity goes towards keeping us cool. To reduce this energy demand, scientists have been searching for passive ways of cooling us that don’t require electricity.

Jia Zhu at Nanjing University in China and Shanhui Fan at Stanford University and their colleagues were inspired by silk, which feels cool against the skin because it reflects most of the sunlight that strikes it – mainly the infrared and visible wavelengths – and so readily radiates heat.

They were able to engineer silk to block even more sunlight – about 95 per cent – by embedding the fibres with aluminium oxide nanoparticles that reflect the ultraviolet wavelengths of sunlight.

Apparently, this is the 12th lowest-ever-recorded extent of arctic sea ice, this year, 2021. Twelf lowest is pretty low.  But the arctic ice expanse is 26 percent bigger than it was just a year ago.  Even though warming trends continued this year, it looks like ice melting has still managed to slow.  This is one  of those half glass of water being half empty or half full kind of things.

Whatever might be occuring or not occuring as a result of man-made climate change, the patterns are sure to be complex and yield results that, at least so far, no computer model seems to accurately be able to predict.  Let’s hope the ‘scientists’ don’t get locked into an easy fix that satisfies the political wants and needs of the mostpowerful when they come up with their surefire fixes to cure climate change.  Thank God something like that could never happen, though, ever.

Arctic Sea Ice Extent 26% Greater Than Last Year – But Still 12th-Lowest on Record

Sea ice covered more area this summer compared to recent years, but it was also much thinner.

Sea ice in the Arctic Ocean and neighboring basins appears to have hit its annual minimum extent on September 16, 2021, after waning in the spring and summer. The summertime extent is the twelfth lowest in the satellite record, according to scientists at the National Snow and Ice Data Center and NASA.

The map at the top of this page shows the sea ice extent on September 16, 2021. The ice extent (white) on that day—defined as the total area in which the ice concentration is at least 15 percent—measured 4.72 million square kilometers (1.82 million square miles)—higher than in recent years. Sea ice extents in 2020 and 2019 were the second and third lowest on record at 3.74 million square kilometers in 2020 and 4.14 million in 2019.

Less sea ice melted in 2021 even as the planet as a whole was warmer than usual—with new temperature records in North America and…
