pathogens. Experimental studies crossing the presence/absence of the bacteria with the presence/absence of a specialized garden pathogen — a fungus in the genus Escovopsis — have shown that ants with antibiotic-producing bacteria are better able to protect their fungal gardens from disease. These studies are among the best evidence that at least some antibiotics suppress infections in nature. T...

Dear Editor-in-Chief, Influenza, commonly known as the flu, is an infectious disease caused by an influenza virus (1). Symptoms can be mild to severe (2). The most common symptoms include: high fever, runny nose, sore throat, muscle pains, headache, coughing, sneezing, and feeling tired (1). Three of the four types of influenza viruses affect people, Type A, Type B, and Type C (3, 4). Type D ha...

In this paper we present a method of automatic color correction of face images and its application in a face detection algorithm. The color correction method is based on the phenomenon of color constancy observed in human visual perception. This technique is further applied in a face detection system, which draws upon the analogy to the parallel organization of visual neural pathways, the magno...

Three-dimensional spatiotemporal tracking of microscopic particles in multiple colors is a challenging optical imaging task. Existing approaches require trade-off between photon-efficiency, field view, mechanical complexity, spectral specificity and speed. Here, we introduce multiplexed point-spread function engineering that achieves photon efficient, 3D, multicolor particle over large view. Th...

Several lines of evidence indicate that the processing of motion by the primate visual system continues even when a moving stimulus differs from its surroundings by color alone. To illuminate the mechanisms by which our visual system uses color as a token for motion correspondence, we have developed an "apparent motion" paradigm in which red/green sine-wave gratings undergo reversal of chromati...
