More light than heat

Osteonecrosis of the jaw: more heat than light.

Osteonecrosis of the jaw has received a great deal of attention in the past few years. The earliest case reports claimed that the only time it ever occurred was as a complication of therapy with bisphosphonates and that both oral and intravenous bisphosphonates were implicated (1). These reports led to use of terms such as BRONJ (bisphosphonate-related osteonecrosis of the jaw). The speculation...

The demand for information: More heat than light

This paper produces a theory of the value of Gaussian information given two states and two actions, tracing the solution of the option pricing formula, but for the process of beliefs. We derive explicit formulas for the value of information. The marginal value is convex and rising, concave and peaking, and finally convex and falling. As the price falls, demand is initially zero, and eventually ...

Light - Much More Than Vision

A brief overview of the impact of light on the circadian system is given, which underscores the importance of developing a framework for circadian photometry. The amount of light, its spectral composition, spatial distribution, timing and duration needed for vision is so different from that needed for circadian functioning, that generalizations about “good lighting” will have to be assessed by ...

Light Perception: More Than Meets the Eyes

Larval zebrafish lacking eyes and pineal organ show elevated activity levels and undirected light-seeking behaviour upon loss of illumination. This behaviour, termed dark photokinesis, is mediated by hypothalamic deep brain photoreceptors expressing melanopsin.
