People who survive a bout of Covid-19 with mild symptoms or even no symptoms may be able to thank their Neanderthal ancestors, a new study suggests.
Researchers found a genetic mutation that reduces the risk of severe Covid-19 infection by about 22%. It was found in all the samples they took of Neanderthal DNA, and in about 30% of samples from people of European and Asian origin.
The genetic region involved affects the body’s immune response to RNA viruses such as the coronavirus, as well as West Nile virus and hepatitis C virus, the researchers reported Tuesday in the Proceedings of the National Academy of Sciences…
The finding could help explain why Black patients are so much more likely to suffer severe coronavirus disease. Neanderthals, who went extinct about 40,000 years ago, lived alongside and sometimes interbred with modern humans in Europe and Asia but not in Africa, and people of purely African descent do not carry Neanderthal DNA. Studies estimate that about 2% of DNA in people of European and Asian descent can be traced back to Neanderthals.
RTFA. Details on the research. And it’s certainly interesting to our household. Genetic analysis shows my wife with about 2% Neanderthal DNA. I’m actually at about 3%.
…and if there’s anyone consulting/advising investors with deserved reputation for good sense, honest analysis and understanding of political economy moving a whole society forward, it’s Barry Ritholtz. Not the first this proposal appeared on TWITTER; but, Barry makes a brief, concise argument for Tesla buying Ford.
Even though just a tad over 2 years ago, folks were suggesting the reverse deal.
An international team of researchers led by archaeologist Dr. Angela Perri, of Durham University, UK, looked at the archaeological and genetic records of ancient people and dogs.
They found that the first people to cross into the Americas before 15,000 years ago, who were of northeast Asian descent, were accompanied by their dogs.
The researchers say this discovery suggests that dog domestication likely took place in Siberia before 23,000 years ago. People and their dogs then eventually travelled both west into the rest of Eurasia, and east into the Americas…
The Americas were one of the last regions in the world to be settled by people. By this same time, dogs had been domesticated from their wolf ancestors and were likely playing a variety of roles within human societies.
Nicely enough, they still do.
As ever, Gary Larson rocks! Even when experimenting with “New stuff” on a digital pad.
Tell the average American voter to “Fish or cut bait!”…
The answer is “Huh?”

As someone who lives in the grays, I immensely appreciate a cold rainy weekend in San Francisco. This morning, I made myself a nice cup of tea and sat down on the writing table with my iPad, hoping to spend time reading some articles and catching up on books that have slowly started to pile up on the bed-stand. For some odd reason, I began to look at some of my older photos. I had edited them over the past twelve months.
As I flipped through the gigantic photoshop files, it felt as if I was looking at the work of someone else. I felt assaulted by the colors — even though I had stripped out the extraneous as much as I could. It is not as if I don’t enjoy a beautiful sunset or a glorious sunrise. It is not that I don’t enjoy the pinks, mauve, and gentle oranges over the breaking waves of the Pacific. However, when it comes to the visual interpretation of these same landscapes, I can’t help wrinkling my proverbial nose as if the color was a piece of rotting vegetation?
How did I end up here? Why? I often ask myself.
I always enjoy Om’s musings. Whether the topic is writing about the technical machinery that seems to be cranking full speed in his neck of the prairie…or photography…he’s just about always addressing something of interest to me.
I’m not the dedicated photographer I have been in decades past; but, my interest has never waned. Om’s style and commentary always finds the heart of whatever values he examines.
The voting patterns of religious groups in the U.S. have been scrutinized since the presidential election for evidence of shifting allegiances among the faithful. Many have wondered if a boost in Catholic support was behind Biden’s win or if a dip in support among evangelicals helped doom Trump.
But much less attention has been paid to one of the largest growing demographics among the U.S. electorate, one that has increased from around 5% of Americans to over 23% in the last 50 years: “Nones” – that is, the nonreligious.
I am a scholar of secularism in the U.S., and my focus is on the social and cultural presence of secular people – nonreligious people such as atheists, agnostics, humanists, freethinkers and those who simply don’t identify with any religion. They are an increasingly significant presence in American society, one which inevitably spills into the political arena.
The voters characterized as the “religious Right” continue at least as noisy as ever…while their economic and political power diminishes outside of the opportunist brigade in the Republican Party. And Trump has shattered that segment badly enough that it may be reduced to the same sort of historic footnote as George Wallace’s American Independent Party.
Meanwhile, I find Professor Zuckerman’s article encouraging – offering hope for scientific realism, hard facts, playing more of a role in American politics. Finally!
