Semicarbazide (SEM) is a metabolite of the banned veterinary antibiotic nitrofurazone [1]. In addition, SEM is a decomposition product of azodicarbonamide (which belongs to the hydrazine family of chemicals). SEM has in fact been found in food in glass jars sealed with plastic gaskets manufactured using azodicarbonamide as a blowing agent, such as baby foods, fruit juices, jams to prevent leaka...

The echolocation behavior of Pipistrellus abramus during exposure to artificial jamming sounds during flight was investigated. Echolocation pulses emitted by the bats were recorded using a telemetry microphone mounted on the bats' backs, and their adaptation based on acoustic characteristics of emitted pulses was assessed in terms of jamming-avoidance responses (JARs). In experiment 1, frequenc...

Chemical analyses of ancient organics absorbed into pottery jars from the beginning of advanced ancient Egyptian culture, ca. 3150 B.C., and continuing for millennia have revealed that a range of natural products--specifically, herbs and tree resins--were dispensed by grape wine. These findings provide chemical evidence for ancient Egyptian organic medicinal remedies, previously only ambiguousl...
