Four in ten children in Central London who travelled to school by car switched to more active modes of transport, such as walking, cycling, or public transport, following the introduction of the Ultra-Low Emission Zone (ULEZ), according to new research. In the comparison area with no ULEZ, Luton, only two in ten children made this switch over the same period.

Researchers have developed a sensor made from ‘frozen smoke’ that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors.

Cambridge Zero symposium gathers researchers to examine the connections between planetary and public health.

A new study led by Cambridge ̽»¨Ö±²¥ confirms that planting hedges between roadsides and school playgrounds can dramatically reduce children’s exposure to traffic-related particle pollution.

Analysis of global tracking data for 77 species of petrel has revealed that a quarter of all plastics potentially encountered in their search for food are in remote international waters – requiring international collaboration to address.

A conference organised by Pembroke College, Cambridge Conservation Initiative and WildFish Conservation has mobilised activists working to save chalk streams - one of the world's rarest habitats - from pollution and over-abstraction.

̽»¨Ö±²¥London Underground is polluted with ultrafine metallic particles small enough to end up in the human bloodstream, according to ̽»¨Ö±²¥ of Cambridge researchers. These particles are so small that they are likely being underestimated in surveys of pollution in the world’s oldest metro system.

Researchers have developed a new method for assessing the impacts of ozone-destroying substances that threaten the recovery of the ozone layer.
