Buzzing off
to implement testing for MRSA amongst all farm animals. The association say the bacteria are widespread in the Netherlands, Belgium and Germany. In the Netherlands 39 per cent of pigs tested positive for the bacteria strain that can be passed to humans. And 13 per cent of calves carried a different strain from that found in hospitals. These studies also found that 50 per cent of farmers were al...
متن کاملWhy is the lawn buzzing?
Graminoids, including grasses, are frequently described in the botanical literature as being wind-pollinated. This paper offers visual evidence for insect pollination of a grass. Three of the bees involved were found to have 100% grass pollen in their pollen sacs. In reviewing the literature for this paper, it was evident that those working with bees are well aware that these insects often poll...
متن کاملAuditory Neuroscience: How to Stop Tinnitus by Buzzing the Vagus
Recent observations linking the vagus nerve to plasticity in the central nervous system could pave the way to new treatments for one of the most common and intractable disorders of the auditory system.
متن کاملArtificial buzzing lips and brass instruments: experimental results.
Experimental results of a special artificial trombone player are presented: A mechanical device is a substitute for the musician. Wind instruments, and particularly the brass, are self-sustained oscillators. The oscillations are induced by a mechanical oscillator (the lips of the player) acting as a valve which modulates the flow. Measured mechanical parameters of the artificial buzzing lips fo...
متن کاملBuzzing during biosonar-based interception of prey in the delphinids Tursiops truncatus and Pseudorca crassidens.
Echolocating bats and toothed whales probe their environment with ultrasonic sound pulses, using returning echoes to navigate and find prey in a process that appears to have resulted from a remarkable convergence of the two taxa. Here, we report the first detailed quantification of echolocation behaviour during prey capture in the most studied delphinid species, a false killer whale and a bottl...
