Seeing (and picking) spots

Perspective: microarray technology, seeing more than spots.

The publication in the mid-1990s of a new molecular tool, the DNA microarray, has led to a revolution in the way scientists approach the investigation of gene expression and regulation. This technology has made its impact upon many basic scientific disciplines including cancer biology, developmental biology, toxicology, investigation of growth-factor and hormonal signaling, and the applied area...

Seeing and not seeing.

Recent studies revealed that although subterranean mammals inhabit a dark underground environment, they can still perceive light stimuli and use this to entrain their circadian activity rhythm. Regarding spatial orientation, olfactory and tactile cues are employed for short-distance; whereas for long-distance, subterranean mammals employ the earth's magnetic field and self-generated (vestibular...

Seeing Seeing

This paper discusses several key issues concerning consciousness and human vision. A brief overview is presented of recent developments in this area, including issues that have been resolved and issues that remain unsettled. Based on this, three Hilbert questions are proposed. These involve three related sets of issues: the kinds of visual experience that exist, the kinds of visual attention th...

Seeing more is seeing better.
