The social brain hypothesis assumes the evolution of social behaviour changes animals' ecological environments, and predicts evolutionary shifts in social structure will be associated with changes in brain investment. Most social brain models to date assume social behaviour imposes additional cognitive challenges to animals, favouring the evolution of increased brain investment. Here, we presen...

Recently, there has been a growing interest in topics at the intersection of epistemology and externalist philosophy of mind in the form of active externalism. Active externalism, contrary to Putnam and Burge’s content (or passive) externalism, concerns the aspects of the environment that determine the content and the flow of cognition, not by acting as the background which cognition takes plac...

Many studies have demonstrated that the sensory and motor systems are activated during conceptual processing. Such results have been interpreted as indicating that concepts, and important aspects of cognition more broadly, are embodied. That conclusion does not follow from the empirical evidence. The reason why is that the empirical evidence can equally be accommodated by a 'disembodied' view o...

The complete sequence of ART-CH, a recently found chicken retrotransposon (A. V. Gudkov, E. A. Komarova, M. A. Nikiforov, and T. E. Zaitsevskaya, J. Virol. 66:1726-1736, 1992), was characterized. ART-CH has the structure of a 3,300-bp-long provirus, including two 388-bp long terminal repeats (LTRs) (U3, 245 bp; R region, 17 bp; and U5, 126 bp), a tRNA(Trp)-binding site, and a polypurine tract, ...

Using complementary physical-chemical methods including turbidimetry, quasielastic light scattering, gel filtration, and phase analysis, we examined the interactions between dilute concentrations of the common bile salt, taurochenodeoxycholate (TCDC), and uni- and multilamellar vesicles (MLVs) composed of defined molecular species of lecithin (L) and varying contents of cholesterol (Ch). Dissol...

The debate surrounding how emotion and cognition are organized in the brain has recently been drawn toward Damasio’s Somatic Marker Hypothesis. The theory endorses a highly interactive process that emotion has with cognition, but has been criticized for: 1) being too broad to capture the specific processes that emotion offers cognition, and 2) implicitly endorsing that emotion operates from a s...

Feferman is arguably the foremost critic of set theory since Weyl. His paper “Is the continuum hypothesis a definite mathematical problem?” provides a useful overview of his negatie answer, drawing on many papers over many years. The main thesis is that the continuum hypothesis (CH) is an “indefinite” statement and that the underlying reason is that the “concept of arbitrary set [which is essen...
