TL;DR: In this article, a class of π;-conjugated compounds that exhibit large δ (as high as 1, 250 × 10−50 cm4 s per photon) and enhanced two-photon sensitivity relative to ultraviolet initiators were developed and used to demonstrate a scheme for three-dimensional data storage which permits fluorescent and refractive read-out, and the fabrication of 3D micro-optical and micromechanical structures, including photonic-bandgap-type structures.

Two-Photon Laser Scanning Fluorescence Microscopy
TL;DR: The fluorescence emission increased quadratically with the excitation intensity so that fluorescence and photo-bleaching were confined to the vicinity of the focal plane as expected for cooperative two-photon excitation.

Association of human papillomavirus types 16 and 18 E6 proteins with p53.
TL;DR: This study shows that the E6 protein of HPV-16 is capable of binding to the cellular p53 protein, providing further evidence that the human papillomaviruses, the adenovirus type 5, and SV40 may effect similar cellular pathways in transformation.
