A chemical conspiracy?

Untangling a deadly conspiracy

Molecular mothbal ls for RNA S tressed-out cells pack away all but their crucial messenger RNAs for better times. The zipcode binding protein (ZBP1) functions as a preservative for the stored RNA, as Stöhr et al. report on page 527. By sheltering some cached molecules, the protein might help cells to recover quickly once conditions improve. Heat, reactive oxygen species, and other harsh stimuli...

Conspiracy theories in science.

Conspiracy theories are easy to propagate and difficult to refute. Fortunately, until a decade or so ago, few serious conspiracy theories haunted the natural sciences. More recently, however, conspiracy theories have begun to gain ground and, in some cases, have struck a chord with a public already mistrustful of science and government. Conspiracy theorists—some of them scientifically trained—h...

Sibling Conspiracy Number Search

For some two-player games (e.g. Go), no accurate and inexpensive heuristic is known for evaluating leaves of a search tree. For other games (e.g. chess), a heuristic is known (sum of piece values). For other games (e.g. Hex), only a local heuristic — one that compares children reliably, but nonsiblings poorly — is known (cell voltage drop in the Shannon/Anshelevich electric circuit model). In t...

Conspiracy in bacterial genomes

The rank ordered distribution of the codon usage frequencies for 123 bacteriae is best fitted by a three parameters function that is the sum of a constant, an exponential and a linear term in the rank n. The parameters depend (two parabolically) from the total GC content. The rank ordered distribution of the amino acids is fitted by a straight line. The Shannon entropy computed over all the cod...
