New research into this question shows that the second wave of an epidemic is very different if a population has a homogenous distribution of contacts, compared to the scenario of subpopulations with diverse number of contacts. The research, by American authors from Oakland University, Novi High School, and California Polytechnic State University, used a simulation...
New research has revealed the locations and industries in the USA where efforts to improve water consumption would have the greatest benefit for economic activity and the environment. The study, led by researchers from Virginia Tech, used a spatially detailed database of water productivity to set realistic benchmarks for more than 400 industries and products....
A new study has revealed how remora suckerfish detach themselves from the surfaces they’ve clung to – and how the mechanism could provide inspiration for future reversible underwater adhesion devices. The research, by an international, multidisciplinary team working across robotics, comparative biology, and electrical engineering, investigated the detachment mechanism of the remora’s suction disc, and...
Researchers in China have taken the first step towards a new way of treating gastric wounds by using a microrobot combined with the new concept of “in situ in vivo bioprinting” to carry out tissue repair inside the body. Their study, published today in the IOP Publishing journal Biofabrication, establishes proof-of-concept for this new method...
Large improvements of air quality in China during the COVID-19 lockdown have been widely reported, but new research reveals that the two pollutants most harmful to human health, fine particulate matter (PM2.5) and ozone, were only slightly reduced. The study, by scientists from the University of Leeds, UK and the Southern University of Science and...
Any uptake in electric vehicle use must be mirrored by the development of clean energy grids to mitigate both climate change and air pollution. That is the key finding of a new study by researchers at the Lawrence Berkeley National Laboratory, California, and Stanford University, California. Published in the IOP Publishing journal Environmental Research Letters,...
A study examining the urban microclimatic impact of the 2019-20 Australian bushfires has uncovered how they affect local meteorological and air quality. Its findings could help understand the potential consequences of an increased rate and extension of bushfires, and especially regarding improving risk preparedness and coping strategies. The research was carried out by scientists from...
Researchers in the USA have developed a graphene-based electrochemical sensor capable of detecting histamines (allergens) and toxins in food much faster than standard laboratory tests. The team used aerosol-jet printing to create the sensor. The ability to change the pattern geometry on demand through software control allowed rapid prototyping and efficient optimization of the sensor...
Researchers in the US have developed a new multi-organ-on-a-chip to test how new drugs affect the human body’s vital organs. Developing new drugs can come at enormous financial cost, which can be wasted if the drug must be withdrawn due to unforeseen side effects. The research team believes their new system – containing representations of...
The way research in bioprinting will be taken forward has been laid out in a roadmap for the field. Published today in IOP Publishing’s Biofabrication, leading researchers define the status, challenges and opportunities in the field, and forecast the required advances in science & technology to overcome the challenges to a range of bioprinting techniques...
A team of researchers in Canada have successfully trialled a new handheld 3D skin printer, which treats severe burns by ‘printing’ new skins cells directly onto a wound. Although the new system is in the early stages of development, it may eventually provide a way to treat patients whose burn injuries are too extensive to...
Encompassing more than 1,500 references and the knowledge of 70 co-authors from EU-funded Graphene Flagship partners and associate members, the article aims to provide a single source of knowledge on graphene and related layered materials (GRMs). Graphene is already being used in many commercial applications, with numerous new products on the horizon. However, lack of...
