Discovery—literally, the act of uncovering—implies a new and fundamental observation that changes the way in which we view and respond to the world (Image 1). Eureka (‘‘I have found it’’) moments are rare in science. Given the physiques of many scientists, this may be a good thing. Legend has it that when Archimedes discovered while bathing that the volume of an object could be calculated by fi...

a study was carried out to determine whether naturally-occurring weeds and other cultivated plants in tomato growing regions could act as symptomless reservoirs of infection to fusarium oxysporum f. sp. lycopersici. a numher of f. oxysporum isolates from weeds and oubergines were used in this investigation. a susceptible tomato cultivar was used for comparison. the plants were artificially ...

Different species inhabit different sensory worlds and thus have evolved diverse means of processing information, learning and memory. In the escalated arms race with host defense, each pathogenic bacterium not only has evolved its individual cellular sensing and behavior, but also collective sensing, interbacterial communication, distributed information processing, joint decision making, disso...

The development of sensors for detecting foodborne pathogens has been motivated by the need to produce safe foods and to provide better healthcare. However, in the more recent times, these needs have been expanded to encompass issues relating to biosecurity, detection of plant and soil pathogens, microbial communities, and the environment. The range of technologies that currently flood the sens...
