Fueling Clean Household Environments

Fueling Synapses

The transmission of information across neuronal synapses is an energetically taxing business. Sheng and colleagues monitored the localization of mitochondria following different levels of synaptic activation and discovered that these organelles change their distribution in interesting ways, stalling near synapses when neurons are activated and increasing their movement when neurons are silent (...

Classifying Human Activities in Household Environments

The recognition of daily human actvitities is becoming more and more important for humanoid robots. For the robot, being a daily companion of the human, it is crucial that it is able to understand what the human is doing in order to react accordingly. Although there exist many systems for recognising human activities there is a lack of having a structured classification of these activities. In ...

COVER A circulator for sound. The arrows represent acoustic signals fl owing through the device (diameter: ~20 centimeters), which circulates sound in a nonreciprocal fashion: Signals can fl ow from left to top, from top to right, and from right to left, but not in the opposite directions. This creates one-way communication channels for sound, allowing listeners to hear but not be heard in retu...

Exploiting Microbes and Plants to Clean up Pesticide Contaminated Environments

This journal is © The Royal Society of Chemistry 2002 Background Microbes and plants are among the most important biological agents that remove and degrade waste materials to enable their recycling in the environment. Whilst these agents are adapted to tackle most naturally occurring substances, many modern synthetic chemicals present a challenge to their remediating capabilities. The fact that...
