Infrared detection in a beetle

Article Abstract:

Buprestid beetles of the Melanophila genus need freshly burnt wood to develop their larvae, but neither olfactory nor auditory senses are used to detect forest fires. A study found that their pit organs respond to infrared radiation, providing evidence of an insect infrared receptor, which could be used in the identification of infrared emissions from a forest fire. The study used electrolytically sharpened tungsten electrodes to record activity of the sensillum, located at the bottom of each pit. It also found that the beetle's infrared receptors responded to mechanical deformation.

A new non-isotopic detection system for immunoassays

Article Abstract:

Origen, an electrochemiluminescent (ECL) detection system is a novel technique for conducting immunoassays. Developed by Igen, the system's major advantages include the number of ways the assays can be formatted for the instrument and low investment of labor. This system empowers the investigators to design both separation and nonseparation assays. Because it does not incorporate certain radioimmunoassay procedures, or enzyme-linked immunoabsorbent techniques, the ECL detection system is flexible.

Detection of environmental fine structure in the low-energy beta-decay spectrum of (super187)Re

Article Abstract:

Neutrino masses can be measured in principle from small distortions in electron spectra, emitted during low-energy beta-decay processes. A cryogenic microcalorimeter was used to to detect beta environmental fine structure in the beta-decay spectrum of (super187)Re. The results agree well with recent theoretical predictions and may help to further studies of molecular structures in a similar way to extended X-ray absorption fine structure.
