Blogging again.
This time it will most likely be from my delicious bookmarks. I’ve come up with the idea of using @[service] tags to send content to different services. Currently I’m using @twitter ;^) to tweet certain bookmarks and there’s no reason I can’t @tumblr as well from here in.
Tada! All of this content gets syndicated from bookmarks as a way to keep all of me in the one place,...

This paper describes a new automata which is Turing Complete. These algorithms use a data structure which can be described as an abstract graph representation. The construction of this machine can be…
In many fungi, reproductive spores are remarkably... →
In these species[ascomycetes], spores are held in fluid-filled sacs where pressure builds until they eventually explode, ejecting the spores into the surrounding air. An optimal drag-minimizing shape…

“A Fock state, in quantum mechanics, is any state of the Fock space with a well-defined number of particles in each state” “Technically, the Fock space is the Hilbert space made from the direct sum…
What is the effect of fluoxetine on mast cell? →
Chronic heterotypic stress may induce the immune responses in gastric mucosa. Treatment with fluoxetine can ameliorate pathological changes in gastric antrum of depressed rat model, suggesting that…
Increased daily travel in animals leads to more... →
The pair determined that over evolutionary time, increasing travel distance is often part of a strategy for procuring food energy and not necessarily a response to decreased food availability.
