The health benefits of walking and cycling outweigh the negative effects on health of air pollution, even in cities with high levels of air pollution, according to a study led by researchers from the Centre for Diet and Activity Research (CEDAR) and Medical Research Council Epidemiology Unit at the University of Cambridge. This new evidence strengthens the case for supporting cycling even in polluted cities – an effort that in turn can help reduce vehicle emissions.
An international study of almost 120,000 women has newly identified five genetic variants affecting risk of breast cancer, all of which are believed to influence how breast cells respond to the female sex hormone oestrogen.
Researchers have modelled how wetlands might respond to rising sea levels, and found that as much as four-fifths of wetlands worldwide could be lost by the end of the century if sea levels continue to rise.
Researchers have shown that graphene can be used to make electrodes that can be implanted in the brain, which could potentially be used to restore sensory functions for amputee or paralysed patients, or for individuals with motor disorders such as Parkinson’s disease.
A major showcase of companies developing new technologies from graphene and other two-dimensional materials took place this week at the Cambridge Graphene Centre.
Researchers have successfully demonstrated how several of the problems impeding the practical development of the so-called ‘ultimate’ battery could be overcome.
Pollution causes 30,000 people a year in the UK to die early yet most of us are unaware of the degree to which we are exposed to it. Low-cost pollution detectors could provide the answer.
