We cast aspects of consciousness in axiomatic mathematical terms, using the graphical calculus of general process theories (a.k.a symmetric monoidal categories and Frobenius algebras therein). This calculus exploits the ontological neutrality of process theories. A toy example using the axiomatic calculus is given to show the power of this approach, recovering other aspects of conscious experience, such as external and internal subjective distinction, privacy or unreadability of personal subjective experience, and phenomenal unity, one of the main issues for scientific studies of consciousness. In fact, these features naturally arise from the compositional nature of axiomatic calculus.

It has been argued that fungi have cognitive capacities, and even conscious experiences. While these arguments risk ushering in unproductive disputes about how words like "mind," "cognitive," "sentient," and "conscious" should be used, paying close attention to key properties of fungal life can also be uncontroversially productive for cognitive science. Attention to fungal life can, for example, inspire new, potentially fruitful directions of research in cognitive science.

The existence of free will has been called into question by Benjamin Libet's seminal experiment, who argued that our conscious decision is preceded by an unconscious decision reflected in the readiness potential (RP). Alternatively, it has been argue that the RP rather reflects a decision process in which different signals accumulate until they reach the intention threshold, at which point an agent experience their intention simultaneously. This raises the question what type of signal is accumulated given that no external information is provided.

Importance: Black individuals have a twofold higher rate of prostate cancer death in the US compared with the average population with prostate cancer. Few guidelines support race-conscious screening practices among at-risk Black individuals.
Objective: To examine structural factors that facilitate or impede access to prostate cancer screening among Black individuals in the US.

Fluctuations in the presence, experiential quality and contents of consciousness occur naturally during sleep and wakefulness and are core features of the healthy human mind. The purpose of this article is to consider the possibility that such fluctuations, including mind wandering and dreaming, which we refer to collectively as spontaneous thoughts and experiences (STE), may also be important elements of experience in certain patients with disorders of consciousness (DoC). The presence of these states may have urgent implications for DoC diagnosis, which centres on the detection of consciousness.

Cyclists frequently experience task failure, an abrupt inability to maintain high-intensity effort, pushing both physiological and psychological boundaries. Although the physiological underpinnings of task failure are well-documented, the associated subjective and perceptual experiences remain underexplored. To address this gap, we surveyed 2,818 licensed cyclists, gathering extensive data on the subjective aspects of reaching the point of exhaustion.
