“Why don’t you just find an HIV-negative man and settle down?” was the question that a psychotherapist posed to one HIV-negative man I interviewed whose lover had died of AIDS. I imagine the therapist’s tone was that of a Jewish mother chiding her daughter to “find a nice Jewish boy.”

The longstanding ‘polyelectrolyte theory of the gene’ proposes that a multiply charged backbone is the universal signature of all genetic polymer systems that support life. Now, the first tenable challenge to this theory has been mounted, through the successful engineering of enzymes which can synthesize and reverse-transcribe from an artificial ...

Negative Properties—Negative Objects?
Acta Analytica, 2018This paper starts with the presentation of an Aristotelian theory of negative properties. Against this backdrop, it then asks whether there could be objects that have solely negative properties, i.e., completely negative objects. This possibility is entertained by Wittgenstein in his Tractatus Logico-Philosophicus.

When is a negative study not negative?
International Journal of Radiation Oncology*Biology*Physics, 1997Results of Phase III randomized clinical trials can be categorized into three groups: positive, null, and negative. The jargon used in discussing results of comparative studies requires clarification because misclassification can result in incorrect interpretation.

Negative reaction to negative refraction
Physics World, 2002If you think science is a smooth progression towards objective truth then a dispute in the normally cordial world of optics research might make you think again. The disagreement concerns one of the most fundamental and best-known phenomena in optics – refraction.
