science. Daytime science is made of the polished, linear, rigorous stories you can read in a journal such as this one, or hear in talks. Night-time science is the messy heap of intuition, despair or elation, association of seemingly unrelated ideas, absolute absence of rigour, that feeds daytime science. To me, night-time science is the creative, exciting bit. The polishing, rigor, and so on, h...

The field of artificial intelligence (AI) is all about creating systems that exhibit “intelligent” behavior. Computer games have been one of the most visible application areas for innovative AI research and, in part, this has led to numerous major success stories. However, fifty years of AI research has seen the recipe for building strong programs evolve from the early knowledge-intensive appro...

Storytellers have many strategies for luring in their audience and keeping them interested. These include standardized narrative structures, vivid characters, breaking down long stories into episodes, and subtle methods of reminding the readers of facts they may have forgotten. The typical style of writing mathematics systematically avoids these strategies, since the explicit goal is “proving a...

The Internet hosts an abundance of science video resources aimed at communicating scientific knowledge, including webinars, massive open online courses, and TED talks. Although these videos are efficient at disseminating information for diverse types of users, they often do not demonstrate the process of doing science, the excitement of scientific discovery, or how new scientific knowledge is d...

BACKGROUND/AIMS We have shown that A(3) adenosine receptor mediates apoptosis in human lung cancer cells such as A549 cells, an epithelial adenocarcinoma cell line, and Lu-65 cells, a giant cell cancer cell line, via each different signaling pathway. AMID, a pro-apoptotic protein, induces caspase-independent apoptosis by accumulating in the nucleus. The present study investigated AMID-dependent...
