Wearable sensor technologies are essential to the realization of personalized medicine through continuously monitoring an individual’s state of health. Sampling human sweat, which is rich in physiological information, could enable non-invasive monitoring. Previously reported sweat-based and other non-invasive biosensors either can only monitor a single analyte at a time or lack on-site signal processing circuitry and sensor calibration mechanisms for accurate analysis of the physiological state.

Nature has created excellent technologies around us, and as such, it is the chief mentor to humans on creativity and technology development. Nature uses fibre as a building block – natural structures like wood, bamboo, bone, muscle, etc. all have fibrous structure. Fibre spinning and weaving technologies are available in nature since time immemorial. Nature has also demonstrated sophisticated technologies useful in the development of technical textiles like functional surfaces, camouflage, structural colour, thermal insulation, dry-adhesion, etc.

Heterogeneous photocatalytic oxidation (PCO) is one of the most active research areas in environmental purification. Recently, research on PCO technologies-based air cleaners and building materials has been intensively conducted for indoor/outdoor air treatment. The innovative technology is dedicated to decompose gaseous pollutants using photocatalysts under illumination of UV or solar light without extra energy added. Comprehensive knowledge on the properties and performance of PCO for treatment of air using batch reactors or continuous reactors has been established.

Self-consciousness would seem to be a sine qua non for moral competence in a social world. You and we are morally competent in no small part because you know what you ought to do, and we know what we ought to do. A mouse, in contrast, cannot say to itself: “I ought to share this cheese, even if my brother refuses to do so.” But can robots be self-conscious?

In 2010 an estimated 31% of the food in U.S. stores and homes went uneaten, and Americans shipped approximately 34 million tons of food waste to landfills. When food decomposes under anaerobic conditions—for instance, buried beneath other waste in a landfill—it produces methane, a highly potent greenhouse gas. According to the U.S. Environmental Protection Agency, landfills are the third largest producer of methane in the United States, accounting for about 18% of methane emissions in 2013.2
