A small ventilation failure alarm which can be used with all types of lung ventilator is described. The entire patient circuit can be removed and autoclaved easily. Activation of the unit is by a removable key, a mains failure warning is provided, and alarm may be muted during aspiration of secretions from the tracheobronchial tree.

Most people find it profoundly difficult to name familiar smells. This difficulty persists even when perceptual odor processing and visual object naming are unimpaired, implying deficient sensory-specific interactions with the language system. Here we synthesize recent behavioral and neuroimaging data to develop a biologically informed framework for olfactory lexical processing in the human bra...

We studied the efficiency and effects of the multiple sensory cues of tiger moths on echolocating bats. We used the northern long-eared bat, Myotis septentrionalis, a purported moth specialist that takes surface-bound prey (gleaning) and airborne prey (aerial hawking), and the dogbane tiger moth, Cycnia tenera, an eared species unpalatable to bats that possesses conspicuous colouration and soun...

The diversity of courtship displays throughout the animal kingdom is immense and displays can range from seemingly simple, to incredibly complex. Signalers often possess elaborate morphological adaptations for signals directed at a specific sensory modality in receivers. In some cases, these signals are so compelling to human observers, the possibility that important signals exist in other sens...

Mice that lack the adaptor protein DAP12 defy deadly bacterial infections, according to Turnbull and colleagues on page 363. DAP12-deficient mice developed a muted inflammatory response, allowing the immune system to clear the bacteria without triggering septic shock. DAP12 is a transmembrane adaptor protein that is associated with an array of DAP12-deficient mice (dotted line) are resistant to...
