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.
Requiring drones to identify and authorise themselves before they can fly, which could be achieved by fitting them with SIM cards, could help to protect people's privacy by providing an effective way to register both users and machines, according to air traffic management expert Robin Garrity. He has been working on the U-space plan, which sets out a vision for how drones can be integrated into airspace, particularly in urban environments. It is part of work being conducted by the SESAR Joint Undertaking, a public-private partnership that coordinates EU research activities in air traffic management.
Evolution could be partly based on environmental adaptation and not just random mutations, re-opening a centuries-old debate between Charles Darwin and Jean-Baptiste Lamarck, according to Professor Thomas Carell from Ludwig Maximilian University in Munich, Germany.
There are likely to be many more ingredients for life on Saturn’s moon Enceladus than those identified so far, says Dr Frank Postberg from the University of Heidelberg, Germany, the lead author of a paper published on 27 June which revealed the presence of complex carbon-based molecules in the moon's core. He says a fresh mission could reveal a ‘rich zoo’ of such organic molecules and provide solid proof of life beyond Earth.
New observations may provide alternative explanations for dark energy.
The technology could work with existing infrastructures, says Prof. Lee Cronin
We need to double-check the evidence on dark energy, as it may not exist at all, says Prof. Subir Sarkar.
