Very pleasing

There is something peculiarly satisfying about publishing an experiment which has, for its central instrumentation, a small magnet suspended by a human hair.

Camels (and alpacas and equids)


There are camels, at least seven of them, in one of the vacant lots adjacent to the Institute. These (the lots, not the camels) are generally dominated by garbage-bespangled weeds and scrubby little trees. Today there is a circus truck, a tent with camel stalls, and a bunch of camels happily chomping the weeds down to the ground. I've seen goats, sheep and even cows used to clear brush, but the camels seem to be eating through the weeds faster than any of these could. The garbage has been removed (hopefully before the camels were let in), and there is a man who looks more like a circus worker than a government worker cutting and hauling away the woody stuff  the camels pass by (actually just throwing it into another one of the vacant lots). It seems like by tomorrow evening they will have to move them to another lot, or bring in fodder. I wonder if the circus is paying for, or being paid for, the use of the lot. Seems like a good deal for both parties.

It is 6C (43F) and sunny, which means that Rostockers think it is summer, and are walking around, admiring the camels. Some college kids have carried their couch onto the waterfront and are setting up a barbeque.  The ice on the harbor has all melted, and the gulls and mallards are looking for handouts.

Given all this, you might rightly ask why I am in the lab on a Sunday, instead of showing my daughter the camels, or walking with my wife, considering that I have excellent student assistants who are doing all of the actual lab work. The answer is that student assistants are not allowed to be in the lab by themselves, regardless of how mature or well trained they might be, or how routine or undangerous the work. So if the animals need to be checked every day, someone has to be here every day to baby-sit whichever student is in that day. This situation has actually gotten somewhat better. For 18 months that someone always had to be me, and I worked 7 days a week unless I was too sick and had to ask a colleague to cover for me. Now I am working with two wonderful post-docs, and only need to be in the lab every third weekend. Soon another graduate student will join us, and it will be every fourth weekend. Of course, the more experiments there are going on, the longer we have to be in the lab each day, and we are at about 6 hours now, and this will increase. So while those 7 day work weeks I was working included two pretty short days, the occasional work weekend will soon mean working almost full time.
This is honestly not so bad, but I’d rather be out watching the camels eat up that vacant lot.

Update: 10 camels, 6 alpacas, 4 miniature ponies, 3 donkeys and 9 horses. Only the camels are out grazing, fodder is being brought in and more tents are being set up in the areas already cleared.

Culturing culture

I am supervising/mentoring/collaborating with two post-doctoral researchers (a.k.a. postdocs), and greatly enjoying the process. They are both smart, hardworking and enthusiastic, and, unlike me, talented experimentalists. I am good at proposing experimental designs, and at inventing or improving upon experimental apparatus, but I managed to get through all my years of training as a biologist without ever being taught the nitty-gritty of laboratory work. I like to make things up as I go along, and work on twelve projects at a time, paying sporadic attention to each, and you can't really do experiments that way. But these two post-docs actually know what they are doing in the lab. It is impressive to see how thoroughly they train the students, how carefully they document their doings, and how well they know their organisms. As a grad student I started working with rotifers with almost no prior knowledge of rotifers, and without any advisor who knew rotifers. I read the literature, but there is a deep cultural knowledge about how to care for aquatic lab animals, with lore and practice around each group, and I had none of that. These two know, and it is wonderful to watch and learn.
