Catalyst returns

In previous years, when Getaway used to be on Channel 9 on Thursday nights, watching attractive people have good holidays in beautiful parts of the world used to win out over watching Catalyst on the ABC. Now that Getaway has skulked away (I thought it had finished altogether, but it seems to be a half hour show on Saturdays now?) I should be able to catch Catalyst every week this year. Wait a minute - there's normally a child to pick up from Scouts on Thursday nights at 8.30. Dang.

Anyway - last night's Catalyst was really interesting.

The first story was about psychopathy and its childhood signs, and research projects aimed at whether it is possible to "re-wire" callous and unemotional children by the way their parents interact with them. That involves lots of getting the kid to look into their eyes, and telling them they love them. Apparently there was a paper published about this last year. Sounds kind of simple, and I would expect you would have to start really early, but it's an interesting idea.

The second story was about the difficulty in getting reliable communications with Antarctica, particularly the inland bases. I have wondered about this, because last year I unsuccessfully searched to see whether any researcher from that continent kept a regular blog. The reason is, it seems, that communications are currently via some rather old satellites in less than ideal orbits, and bandwidth to the place is therefore limited and not always reliable.

Australia is building a couple of microsatellites to fix this. They are really small (20 cm square!) but apparently will greatly improve communication to the place.

There is also this extended interview on the website in which the guy building the satellites is asked "how come these as so cheap, and the NBN satellites will be so expensive?)

And the final story was on a new, very cool, flight and motion simulator at Deakin university that looks like incredible fun to try out.

What a great show.
