The Adverse Effects of Diurnal Light Exposure on Aging Drosophila melanogaster

Creator:

Nash, Trevor N.

Abstract:

The proliferation of light emitting diodes (LEDs) are increasing human light exposure, yet the long-term effects of such exposure remains unknown. The current study aims to address this by measuring the longevity of Drosophila melanogaster kept in several light conditions. Initial longevity testing determined that flies kept in daily light-dark...

Light Transmittance Properties of Biological Tissues of the Red-sided Garter Snake, Thamnophis sirtalis parietalis, Between 450 and 850 Nanometers

Creator:

Bixby, Eric M.

Abstract:

Using a spectrometer and photomultiplier tube, I measured the electromagnetic radiation transmittance properties of three types of tissue-- ventral skin, cardiac muscle, and liver tissue--in the red-sided garter snake Thamnophis sirtalis parietalis between the wavelengths of 450 and 850 nanometers (nm). Control readings were taken using a 10⁻² neutral density...
