Curious Phenomenon during the Late Gale

Quorum sensing: the explanation of a curious phenomenon reveals a common characteristic of bacteria.

In the 1960s bacterial bioluminescence attracted increasing interest among microbiologists and biochemists. Plating seawater samples taken from virtually any place on the globe revealed the presence of bioluminescent bacteria, but at a rather low level of abundance, not more than a few cells per milliliter. A question frequently raised was what function the light emission might have in such “fr...

A curious instability phenomenon for a rounded corner in presence of a negative material

We study a 2D scalar harmonic wave transmission problem between a classical dielectric and a medium with a real-valued negative permittivity/permeability which models a metal at optical frequency or an ideal negative metamaterial. We highlight an unusual instability phenomenon for this problem when the interface between the two media presents a rounded corner. To establish this result, we provi...

the effect of e-64 on the developmental competence of sheep cocs during in vitro maturation

in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.

Interest—The Curious Emotion

Despite their interest in why people do what they do, psychologists typically overlook interest itself as a facet of human motivation and emotion. In recent years, however, researchers from diverse areas of psychology have turned their attention to the role of interest in learning, motivation, and development. This article reviews the emerging body of work on the psychology of interest, with an...
