Wheels down on Mars, once again


First image from Perseverance

NASA folks land on Mars, again. I switched onto the NASA Channel to check on how they were doing…and the lander had chute deployed and about 7 kilometers above the surface of Mars.

It was just halftime in the Europa League football match I was watching; so, I quick ran to get my wet-and-snow walking shoes – to change while watching. I usually start a couple laps of our fenceline at halftime if I’m watching footie and we got a few more inches of snow, last night.

They spiked the landing. Truly fun to watch for an old time science and scifi geek like me. Nice to see reality match fiction.

Texas grid failed from weatherizing mistakes a decade old

Ten years ago, plunging temperatures forced rolling blackouts across Texas, leaving more than 3 million people without power as the Super Bowl was played outside Dallas.

Now, with a near identical scenario following another Texas cold snap, Texas power regulators are being forced to answer how the unusually cold temperatures forced so much of the state’s power generation offline when Texans were trying to keep warm…

To start, experts say, power generators and regulators failed to heed the lessons of 2011 — or for that matter, 1989. In the aftermath of the Super Bowl Sunday blackout a decade ago, federal energy officials warned the grid manager, the Electric Reliability Council of Texas or ERCOT, that Texas power plants had failed to adequately weatherize facilities to protect against cold weather…

But the repeat of the events of a decade ago is raising questions in Austin as to whether the state has failed to ensure power companies are adequately protecting equipment from the elements. At the peak of the blackout, some 45,000 megawatts of generation capacity were offline, leaving more than 4 million Texans without power.

RTFA. Texas’ political hacks seem to be as incompetent, ignorant, as any other politicians that complain about. State, federal, regional, maybe on Mars. They copout on their responsibilities to Texans. Then, try to blame someone else, somewhere else.

Unaffected by Covid? Maybe thank your Neanderthal ancestors

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%.
