Excess emissions from Volkswagen diesels could cause 59 early US deaths
By Liz Kalaugher, environmentalresearchweb. In September 2015, Volkswagen Group of America admitted that it had installed "defeat devices" in certain models of its diesel vehicles. Such devices, which are barred by the US Clean Air Act, assess whether the vehicle is under test and reduce emissions if so. As a result, the 482,000 vehicles in […]

An interview with PASP Editor-in-Chief, Jeff Mangum
Earlier this year we announced a new partnership with the Astronomical Society of the Pacific (ASP) to publish their journal Publications of the Astronomical Society of the Pacific (PASP). With IOP Publishing (IOP) now accepting submissions for PASP and in advance of us publishing the first issue in January 2016, we talk to Editor-in-Chief of […]

Exploring the physics of a chocolate fountain
A University College London (UCL) mathematics student has worked out the secrets of how chocolate behaves in a chocolate fountain, answering the age-old question of why the falling ‘curtain’ of chocolate surprisingly pulls inwards rather than going straight downwards. The results are published today, 25th November 2015, in European Journal of Physics. “Chocolate fountains are […]

Graphene microphone outperforms traditional nickel and offers ultrasonic reach
Scientists have developed a graphene based microphone nearly 32 times more sensitive than microphones of standard nickel-based construction. The researchers, based at the University of Belgrade, Serbia, created a vibrating membrane – the part of a condenser microphone which converts the sound to a current – from graphene, and were able to show up to […]

IOP Publishing launches Quantum Science and Technology
Quantum information science has now become one of the fastest growing areas of research, characterised by its truly multidisciplinary nature and the significant potential it has for wide-ranging technological innovation. In response to this situation, and demand from the community itself, IOP Publishing is pleased to announce the launch of Quantum Science and TechnologyTM, a […]

Using cycling to explain why physics isn’t a drag
Scientists and teachers have combined to develop a simple spreadsheet-based method of teaching aerodynamic drag to 14 and 15 year olds. By measuring the speed of one of their classmates riding a bike, taking a photo to in order to measure the frontal area of the cyclist, the students were able to calculate the drag […]

Wearable energy generator uses urine to power wireless transmitter
Courtesy of the University of the West of England Press Office. A pair of socks embedded with miniaturised microbial fuel cells (MFCs) and fuelled with urine pumped by the wearer’s footsteps has powered a wireless transmitter to send a signal to a PC. This is the first self-sufficient system powered by a wearable energy generator […]

Tropical groundwater resources resilient to climate change
Courtesy of the University College London (UCL) Press Office. Tropical groundwater may prove to be a climate-resilient source of freshwater in the tropics as intense rainfall favours the replenishment of these resources, according to a new study published in Environmental Research Letters. As climate observations show that global warming leads to fewer but more intense rainfalls, […]
