Two covid vaccines share a common thread that might account for blood clotting in rare cases.

Note: I am not a doctor and am not advising anyone on a particular course of action. This piece is intended to inform the general reader.

Arrows point to small purple dots on micrcoscopic exam. These are platelets.

The common thread between the Oxford-AstraZeneca covid vaccine and a similar vaccine from Johnson and Johnson, is the way that instructions for making virus spike proteins are delivered to human cells. Both vaccines use an adenovirus to do the work. …

It’s been playing a shell game for decades. Although we don’t have definitive proof, running a few numbers and observing what real nuclear powers had to do to get nukes makes us suspicious. The world’s last feudal nation doesn’t have the brainpower or the cash that other members of the nuclear club had so we’re skeptical that NK really has the goods.

North Korea says it can launch nukes. Can it?

North Korea, the Hermit Kingdom, the most reclusive and suppressive country on earth has kept the world hostage for decades by threatening attacks against its neighbors, notably South Korea if any nation attempts to interfere with it. …

The pandemic exposed some long-existing gaps in our civic life that had been dismissed or simply overlooked as we ran our busy lives. These gaps can be most easily explained as the duties we owe each other in a free society. Some duties are political like the duty we owe each other to abide by a common set of laws. Other duties are much more in the realm of commerce, the duties businesses owe customers for instance but also, the duties they owe employees and other stakeholders.

Corporate social responsibility means more than being profitable for shareholders.

These duties reveal a social contract, an agreement that’s implied by life in…

It’s not that all good things must pass away, it’s that the conditions that made them good very often evolve obviating their need or possibly turning their results against their initial benefits. Take the Communications Decency Act as an example and specifically Section 230. Passed in 1996, the Act was seen as a way of encouraging Internet use by telling platform providers like message boards that they were not responsible for the postings of their members.

The Declaration of Independence is a great example of Enlightenment thinking.

The act was eminently sensible back then but the nature of communications, exemplified by the rise of social media, has changed so drastically that…

There’s a worthwhile story in the New York Times about the invention of collage, that art form many of us experience in grade school that involves safety scissors that don’t really cut and glue that seems to get everywhere but on the object in question. Ah! Happy days!

What’s cool about Collage is not that it was invented over 100 years ago by the Cubist innovators Georges Braque and Pablo Picasso but what it has to say about the times we live in. These days, when serious people, or at least people with serious jobs, hold forth on space-based lasers…

Logical fallacies are an important part of life as we know it. Sometimes called rationalizations they are blips in logic that we most often use to get something we want though are not entitled to. We use fallacies and rationalizations daily. How important are they? I remember a line from a movie: you can go a day without sex but try going a day without a single rationalization.


Logical fallacies are a part of communicating and we all use them from time to time. They’ve been around so long some have Latin names like, Tu quoque which translates as…

We’re beginning to see social capital redefined as an attribute of corporations in addition to the more common use in describing society at an individual level. At the same time, good will, an imprecise corporate attribute is still very much in use but it’s entirely possible that corporate social capital could come to replace it.

Individual social capital can be brought down to the idea of paying it forward, doing something kind for someone else with no expectation of payback. For example, simple courtesies like yielding in traffic might qualify or holding a door for a stranger. …

Working in parallel, moving the goal posts and avoiding the point

Negotiation is difficult. Practicing it requires skill, patience and experience and like many things in life, it can be done well, or it can be hindered by practitioners who might say they want compromise and not mean it. How do you tell which is which? When is a negotiation on the level and when is it negotiating in bad faith? What are the warning signals that one or both sides might be wasting the other’s time? Here are a few thoughts.

Working in parallel

One reason that negotiations don’t seem to get anywhere is that the parties are discussing two different but related…

Have we been here before?

The new administration is gearing up for a long-awaited push to do something about climate change. And while that’s unarguably a good idea, there’s also a feeling that we’ve been here before. The papers are already running pieces about the anticipated pushback from various parties more fearful of having their profits squeezed than of having their grandchildren run out of potable water. It’s the political equivalent of running in mud and it shouldn’t be this way.

For reasons that aren’t clear Washington seems to have a focus on doing big headline grabbing pieces of legislation rather than smaller pieces that…

A few years ago, I thought the climate was in bad shape and that we weren’t doing enough, anything really, to change the picture. There were and are serious consequences to be faced by the global community regarding climate, I thought. So, to make a contribution, I did what I do best, I wrote a book about solutions. It was a good exercise too because it calmed my anxiety about the climate future. I have a lot of science, especially chemistry, in my background and it was reassuring to discover that, chemically at least, the climate situation was reversible.
