Businesses and consumers need to stop thinking of products as things to own and move towards a culture of sharing and repairing if we are to fulfil the ambition of creating a circular economy, according to Felipe Maya, project and innovation manager at sustainable engineering firm Exergy, headquartered in Coventry, UK.
Research suggests that where we live can affect our mental health but Dr Marco Helbich, an urban geographer at Utrecht University in the Netherlands, believes these studies only offer a limited snapshot of our lives. Using a smartphone app and register data, he is tracking people through their daily routines and their residential history to see whether mental health is affected by where we live, work and socialise. His findings could change how we design our cities.
A group of chemicals known as bi-metallics could help the pharmaceutical industry become more environmentally friendly by cutting the amount of energy used to produce drugs, according to Professor Eva Hevia from the University of Strathclyde, UK, who says that sustainability is a top priority for chemists.
One of the biggest drawbacks of electric vehicles – that they require hours and hours to charge – could be obliterated by a new type of liquid battery that is roughly ten times more energy-dense than existing models, according to Professor Lee Cronin, the Regius Chair of Chemistry at the University of Glasgow, UK.
The most mysterious phenomenon in cosmology – dark energy – may not exist at all, according to Professor Subir Sarkar, head of the particle theory group at the University of Oxford in the UK.
Fathers’ hormone levels and brain activity may change when they spend time with their children, helping them adapt to parenthood in a way that has been overlooked until now, according to Professor Marian Bakermans-Kranenburg, who studies children and family relations at Vrije Universiteit Amsterdam and was until recently at Leiden University in the Netherlands. She is conducting a series of studies with new fathers, to investigate the role that hormones can play in how they bond with their children.
We could get to the stage where atmospheric greenhouse gases are in decline – a point known as drawdown – and begin to reverse global warming before 2050, but it will require us adopting solutions at an aggressive rate, according to Chad Frischmann, vice-president and research director of Project Drawdown.Project Drawdown is a worldwide research and communications initiative with a plan to reverse global warming based on 100 existing and emerging solutions. An independent European arm, Drawdown Europe, has now been launched to galvanise the continent into action.
The pattern of heatwaves causing record breaking temperatures across the northern hemisphere would not be seen without climate change, and they have firmly focused the conversation on what we can do about it rather than whether it’s happening, according to Peter Stott, professor of detection and attribution of climate change at the University of Exeter, UK.
A fold of tissue hidden deep inside the human brain which collects inputs from both inside and outside the body could explain how our physical states influence our emotions and may be the key to understanding anxiety disorders, according to Dr Nadine Gogolla, a neuroscientist at the Max Planck Institute of Neurobiology in Munich, Germany. She is using cutting-edge scientific techniques to probe this poorly studied brain region, known as the insular cortex, to reveal the role it plays in regulating our emotions.
The first day that Jérôme Delafosse stepped aboard the Energy Observer, an experimental catamaran run on hydrogen, he knew the plan of sailing around the world on clean energy was a realistic one, he says. Now, the explorer and documentary maker is one year into a six-year odyssey around the globe with his friend Victorien Erussard, an ocean racer and former cruise ship officer, to prove that the technology can be used for pollution-free ocean travel in the future.
A circular economy needs new business models and reusable products, says Felipe Maya.
The first step in limiting global warming should be curbing energy demand, says Dr Keywan Riahi.
Professor Eva Hevia talks about chemistry’s green movement.
