I once stumbled upon a paper that analyzed rat eating behaviour. They basically change their food source only rarely, and tend to eat whatever they smell other rats are eating. This behavior has lots of advantages. Since they only switch food source when they have to, they seldom eat something poisonous. Since they switch to food they smell other rats have eaten, it is unlikely that the other food is poisonous because otherwise the other rat would have been dead.
This is an extremely robust behavior, and I am sure it can be used in some form as a swarming algorithm, much like ant colony or particle swarm.

Submission + - UK can now hold people without charge for 42 days (bbc.co.uk)

I personally would like to say that I couldn't believe that this was could happen, but I can't. These sorts of laws have been drafted and voted in time and time again in the UK. This particular one holds the probability that even if you're found innocent, by the time the 42 days is up, chances are, everything you've ever had will be gone — job, home, family. Oh there is talk of compensation packages available for the falsely accused, chances of you getting that money however is slim to none, lets not forget, this is the same country that charges prisoners, who have been falsely accused for bed and boarding costs."

Submission + - A timetable for nuclear fusion

IAmTheRealMike writes: This article offers an in depth but readable review of the current state of fusion research, along with a timetable for the future, a description of what still needs to be figured out and a fascinating look at what it'd take to scale up to worldwide commercial generation levels. Executive summary, by 2100 if all goes according to plan fusion might be able to generate 30% of Europes present day demand. The delay is largely due to tightly limited tritium supplies. Whilst a sustainable fusion reactor will produce tritium, it would do so only in small amounts so a reactor would take 2-3 years to produce enough tritium to "give birth" and start another one. It looks like even with the most optimistic assumptions, by the time Tokamak based fusion can meaningfully contribute we will likely be deep in the midsts of an energy crisis.
