Chemical warfare

No, not amongst us humans. But rather as a way for the small hive beetle (Aethina tumida) to infiltrate bees hives. It seams they carry a yeast with them that releases the alarm pheromone that European honeybees use. When the beetles enter the hive, the rising alarm signal disorientates the bees and allows the beetles to do their worst. i.e feed. More details at New Scientist and PNAS. I’m sure Dr. Hellstrom would find this interesting 🙂

Nice use of satire

Peter Olofsson has written an excellent satirical review of the latest Anne Coulter book. Check it out at the Richard Dawkins’ site. Coulter is to be pitied rather than engaged with. Satire is a good way of doing it. 🙂

Papers – Public Preview 2

A 2nd public preview of Papers was released today. Papers is an app for searching PubMed and organising references and PDF files of journal articles. It can also be used to manage any local PDF files already on your Macintosh. It’s like iTunes for scientific papers. The new version interacts with EndNote X which is a nice addition. I’m hoping that Papers will be very useful for a chemistry project course I’ve just started.

Private space flights

There are several private organisations working towards the development of non-governmental space vehicles. See this video of a TEDtalk by Burt Rutan on his efforts with SpaceShipOne. Rutan is now working with Virgin Galactic and Richard Branson to offer private sub-orbital flights. They are also going to build a space port called Spaceport America in New Mexico. Initial flights will go (maybe in 2008) from the Rutan site in the Mojave Desert in California.

Another private venture that had a test flight recently is the Blue Origin group that is funded by Jeff Bezos of Amazon. There are videos of the test flight of their Goddard VTOL craft at the Blue Origin site. This is a prototype of a design called New Shepard thay want to fly sub-orbitally. Whilst it only takes off and rises a few hundred feet then lands safely, it’s a good initial flight.

I’ve been quite sceptical in the past about private space ventures. I’ve argued that it takes the resources of organisations like NASA, RFSA, ESA, JAXA, CNSA or ISRO to fund space programmes. Indeed I’ve argued that it might be better if they joined up and pooled resources.

I think I’ve changed my mind. For the big projects like Mars missions the big agencies are best placed to do them at present. But the smaller private ventures into sub-orbital space could be the start of a bootstrap process that leads to a commercialisation of space flight. This could lead to orbital and extra-orbital flights in time. If there is profit to be made then it’ll get done. It’s only a matter of time. So I now think there is room for both governmental space flight and private space flight.

I find this very exciting. Maybe one day we’ll get to a situation like that depicted in Elite where people can buy their own space craft and make a living wheeling and dealing amongst the asteroids, planets and, ultimately, the stars. For a modern port of this game get Oolite.

Bachelor of Science Open

I accepted a BSc Open from the Open University yesterday. I’m working towards a BSc (Hons) Molecular Science and will complete that next year by doing:

S343 Inorganic Chemistry
SXR343 Transition Metal Chemistry
SXM390 Frontiers of Chemistry

But the points I have, including some courses I’m not using for the Molecular Science degree, means i can take the BSc Open this year. I can now stick BSc Open after my name if I like. Not that I will. Here is the transcript of the courses I did for the Open Degree:
