What Works in Space

And what does not work in space?

This week’s essay is an interesting one for me, because I had written this nearly 30 years ago and amazingly it still makes sense. So, in all these intervening years, hasn’t there been much progress or have I not kept up with developments? The latter may be one reason, but it is also true that by 1989, when this essay was written some basic and important knowledge was already there. And here it is (with some few minor pieces of information added). A former colleague of mine, Prof. Asashima, was one of the founders of the “Society of Space Biologists” in Japan. But what is space biology and what do space-biologists in contrast to exobiologists, who ponder about life on Mars, Ganymede and Europa moons, actually do? —>

Life Between Two Sheets

Tight but nice

When I was living in Canberra (the capital of Australia) we had a pomegranate plant (it was more a bush than a tree) that produced the odd fruit and had beautiful shiny leaves. But some of the leaves contained whitish lines, a kind of roadmap seemingly scribbled onto (or perhaps into) them. And -not to be misunderstood- it is about the upper and lower leaf sheets and what’s between them I want to write. —>


You Hate Something?

So how about the animals: do they hate something too?

Somebody recently told me a vulgar joke about why cats hate dogs and dogs hate cats, but since I hate vulgarity I neither found the joke funny nor will I retell it. However, what the joke did, was to make me think whether animals can indeed hate and express such an emotion usually associated with human behaviour. Obviously, animals can express affection: the cat rubbing its head against your leg (or another cat’s head), dogs licking your hand, baby mice snuggling up to their mother and even a tame koi carp turning on its side to have its belly scratched. But is that love and if it is, is there also the opposite, namely hate? —>
