The future of plastics: reusing the bad and encouraging the good - Guest Work

Guest Work Dec 03, 2017

By Kim Pickering, University of Waikato Plastics have got themselves a bad name, mainly for two reasons: most are made from petroleum and they end up as litter in the environment. We’re reposting this article from The Conversation as part of our Consuming Science series. However, both of these are quite avoidable. An increased focus on … Read More

Anti-fluoride “expert” finds the real reason oral health has improved – and it’s not fluoride - Open Parachute

Ken Perrott Nov 15, 2017

 Anti-fluoride campaigners always promote people like Geoff Pain as “renowned” or “world experts.” They aren’t. Pain has no credible scientific publications on fluoride. No, in fact, he claims lead is responsible for tooth decay and the improvement in oral health is a result of removing airborne lead contamination. And the “proof” is even in the title of his report – … Read More

Severe weather changes may be due to air pollution - Pointing At Science

Steve Pointing Aug 01, 2017

One of the most worrying global trends in climate is a southward shift in the tropical rain belt during recent decades. This has significantly affected rainfall patterns and caused severe impacts on water availability, food production and natural hazards. The impacts have been most pronounced in tropical Africa and South America but this phenomenon may also affect tropical Asia including … Read More

Guest Work Jul 06, 2017

Natalie Welden, Research Associate: Marine Pollution / Ecotoxicology / Microplastics, The Open University After decades of intense observation and campaigning by conservation groups, awareness of microplastic pollution has fortunately grown. There is now worldwide concern about tiny pieces of plastic litter that are having a harmful impact on marine species and habitats. Large plastic litter has already … Read More

How we discovered pollution-poisoned crustaceans in the Mariana Trench - Guest Work

Guest Work Feb 21, 2017

By Alan Jamieson, Newcastle University Even animals from the deepest places on Earth have accumulated pollutants made by humans. That’s the unfortunate finding of a new study by myself with colleagues from the University of Aberdeen and the James Hutton Institute, published in Nature Ecology and Evolution. Up until now I have tended to stick to the nice … Read More

How microbeads in your bodywash could be helping chemicals enter the foodchain - Nano Girl

Michelle Dickinson Sep 06, 2016

In 1976 chemical engineer John Ugelstad invented a technique on earth that other scientists believed could only be carried out in the weightless conditions of space. His discovery enabled the mass production of monodisperse spheres, tiny microscopic spherical plastic beads. The beads were typically 0.5 to 500 micrometres in diameter, about the width of 1 to 5 strands of human … Read More

New Zealand is letting economics rule its environmental policies - Guest Work

Guest Work Aug 23, 2016

By Stephen Knight-Lenihan, University of Auckland Balancing the environment with development is tricky. One way for policymakers to include the value of ecosystems in development is to set limits for pollution and other environmental impacts, known as environmental bottom lines (EBLs). These can be a helpful way of embedding into an economy the value of ecosystems. They also help … Read More
