Hello again Science fans!

How is it Thanksgiving already? Where has this year gone? When I was growing up in the northeast US, Thanksgiving seemed like a logical progression of the weather into winter. Later, when I moved to south Florida, it appeared as a surprise every year, as it was still summery there. It couldn’t possibly be the start of the Christmas season, what with 80 degree temperatures still common!

Here in northern California, we’re somewhere between the two extremes of heat and cold, but we really haven’t had cold days until this week, at least not what constitutes cold for us!

The solstice is weeks away.

Greetings Friends and Fans of Science, Reason, and Doubt!

You will notice that our calendar is a little less full than normal. The holidays do offer some nice diversions to the rigor that scientists practice and share with us. Don’t worry though, there is plenty of science to learn about and share.

The Science Schmooze would like to know.

The old phrase, “May you live in interesting times” seems particularly resonant these days. I have been trying to keep up with a lot of things going on in the news that seem to really be based in, or the denial of, science. I’m stunned by the proliferation of sources of information and how you really need to pay attention to the point of view they look f

Let’s start with a bit of science fun. The above Quantum Steampunk Power Generator was designed by quantum thermodynamics physicist Dr. Nicole Yunger Halpern. Built in collaboration with artist Bruce Rosenbaum, the “Generator” above is a facsimile of an engine that could extract energy by breaking quantum entanglement. The Steampunk Generator helps Dr. Halpern explain how a 'real' quantum generator would work. The Steampunk motif ties in nicely with Halpern’s book,

Hello again Science fans!

Up until 10 years ago, ripples in space-time, predicted by Albert Einstein, remained theoretical. On September 14, 2015, at 4:00 AM, the two LIGO observatories, one in eastern Washington State, the other in Louisiana, detected the signatures of two black holes colliding and merging, and cosmology changed forever. What had been Einstein’s prediction had now been proven. LIGO, and similar installations around the globe, have since detected gravitational waves over 300 times. That discovery, which only lasted 1/5 of a second, was the first, and justified the investment in the observatory in the first place.

Greetings Friends of Science, Reason, and Critical Thinking,

It certainly has been a weird week in news. Including science news. I want to highlight one science topic that has been mostly missed in the news. Most people heard about the Nobel Peace Prize… Sadly it overshadowed nine other people who received it for their work in science and one who received in in literature. (Side note: the Peace Prize winner actually

Hello again, fans of Science.

At the age of 26, Jane Goodall set off to study chimpanzees in Tanzania’s Gombe Stream Game Reserve, armed with little more than a notebook. Unassuming, modest, and optimistic, she literally changed the world with her pioneering discoveries, environmentalism, and general outlook on life and the planet.

Her name is known around the world, by young and old…the woman who lived with the chimpanzees. Her discovery of their tool use and family dynamics changed our understanding of ourselves.

Jane died this week at the age of 91. Here th

In the escalating war on science, our Secretary of Health & Human Services has once again shown his disdain for – or ignorance of – epidemiology by warning pregnant women off of Tylenol. “Hogwash” comes to mind, except that’s a slur against our porcine population. However, i’m not going to burden you with details – you can read about them in Nature magazine. Quick summary: A single study found a difference of 0.0009 in the number of autisms diagnosed with mothers who took Tylenol versus those who did not. That tiny difference disappeared when comparing children with the same mother, i.e. siblings. Other studies failed to find any differences.

Greetings Science Fans, Critical Thinkers, and Skeptics,

I hope that you managed to get in a bit of Sun Day. It is/was September 21st for two big reasons. First, because it’s the solar equinox - one of the two days of the year when all of the world gets an equal amount of sunlight, showing how the sun unites us. Second, September 21st is right before the UN General Assembly’s annual meeting, which means we have an opportunity to send a message to US and world leaders on the urgent need to accelerate and scale-up the just transition to clean ener
