Greetings, dear reader. I trust you will find some delectable items in this week’s science smorgasbord.

SPACE

Learned geophysicists years ago concluded that Mars has a hot liquid inner core, unlike Earth with its hot solid inner core. They calculated that Mars’ gravitational pressure is insufficient to make molten iron solid, as is the case with our home planet. But there’s nothing like good data: the seismometers on NASA’s Insight mission clinched that theory using 

Greetings, I hope you're warming up, SciSchmoozers!

I hope that you are enjoying the weather. Soon it will either be too cold or hot aga

Hello Friends, Fans, and Supporters of Science,

I hope that you haven't started to miss the rain yet.

A couple of months ago I wrote about how science and well established practice were being ignored in our courts and in some parts of governme

Hello Science Fans,

I hope that the break in the weather we have been having has been enjoyable. Quite honestly I rarely check the weather forecast so I can’t comment on what’s ahead, except to let you know that I guarantee there will be weather and we have no option but to deal with it. The other side of that is that I am amazed at how accurate forecasting can be.

It’s time to plan to Eclipse, remember, there will be weather! On Oct 14, 2023 there will be an annu

Welcome again,

We get such good feedback from so many of you that i often think of you as colleagues.

Lately i’ve been living less than a hundred meters from a heavily-traveled 6-lane, 55 mph thoroughfare. (Quick question: ¿Of the world’s 190+ nations, how many officially use “miles” instead of kilometers for road signs? Answer below.) All but a tiny portion of the vehicles zooming by are gobbling up fossil fuel and spewing out CO². There’s not much i can do about that … but i did a little. I made up cards printed on one side, “Make your next vehicle F³ (Fossil Fuel Free). Buy Electric and refuel at home.” On the other side i printed the following:

Welcome dear science-aware reader,

I’ve been slogging through The Climate Book created through the efforts of Greta Thunberg. It is an astounding collection of 84 short ‘essays’ by scientists, economists, visionaries, philosophers, and respected authors. The book has 5 sections:

– How Climate Works
– How Our Planet is Changing
– How It Affects Us
– What We’ve Done About It
– What We Must Do Now

Welcome dear science-appreciative reader,

When Avian Influenza H5N1 is detected in one chicken on an egg farm, it and all of the tens of thousands of other chickens there are destroyed. Over 50 million birds in the U.S. were destroyed this way last year. ¿Why not vaccinate chickens? It isn’t expensive. It’s because eggs and chickens sold for food are tested for infection and the vaccine causes a positive result. A vaccinated bird appears to be an infected bird and cannot be exported for food. ¿What is the danger of eating an infected bird or egg?

Thank you, dear reader, for joining us again and for your kind comments.

Christmas Island Rat, Wooly Mammoth, Passenger Pigeon, Thylacine (a marsupial: carries newborns in a pouch). These animals are extinct but efforts are currently underway to “bring them back.” In each case, researchers are compiling the complete genomes of the extinct animals using frozen carcasses and museum specimens. This 26-minute video on current efforts to de-extinct the Thylacine is fascinating and well-crafted. Personally, i question efforts to de-extinct the Passenger Pigeon. It traveled in flocks numbering in the hundreds of millions that stripped crops and orchards and left towns covered in Passenger Pigeon poop. Best of course is to

Happy New Year, science fans. Thank you for joining me today.

As technology promises better and longer lives, the ‘situation on the ground’ is dismal for much of the world’s 8 billion people - but over the long arc of history, “it’s getting better.” As we and our neighbors and our children tune into how alike we all are - emotionally and physiologically - caring for ‘strangers’ becomes easier. I’m expecting 2023 to show progress in this regard. Consider this for a New Year’s Resolution: I will increase the range of people that I consider to be coequal with myself, deserving of the same rights, dignities, and protections. (Tim Minchin gives an 

Dear reader, so glad you’re reading this. Let me start by laying out some work we need to do.

I love maps of all kinds. The map above is based on Pew Research data of the percentage of people who agreed that "certain people can cast curses or spells that cause bad things to happen to someone." The stippled countries are those with insufficient data. No country had less than 9% of its population believing in wicked witchcraft.
