a study from researchers at Harvard Medical School develops and tests a synthetic microbial system capable of determining the origin of objects, with a view to identifying sources of foodborne illnesses. The team states their DNA-barcoded spores are incapable of growing in the wild, are derived from safe microbe strains, and can be sprayed onto goods such as crops or manufactured products to be detected months to years later.

Using synthetic, DNA-barcoded microbes to track food contamination.

Every year, a staggering 48 million people in the USA alone will suffer from foodborne illnesses, resulting in approximately 128,000 hospitalizations and 3,000 deaths. This public health epidemic is exacerbated … Continue Reading Using synthetic, DNA-barcoded microbes to track food contamination.

Neuroimaging shows the effect of hunger on the brain’s response to food cues.

The decision to engage in food-seeking behaviour depends on homeostatic signals relating to energy balance and the presence of competing motivational drives, as well as learned brain cues signaling food … Continue Reading Neuroimaging shows the effect of hunger on the brain’s response to food cues.
