Although electric vehicles that reduce greenhouse gas emissions attract many drivers, the lack of confidence in charging services deters others. Building a reliable network of charging stations is difficult in part because it's challenging to aggregate data from independent station operators. But now, researchers reporting January 22 in the journal Patterns have developed an AI that can analyze user reviews of these stations, allowing it to accurately identify places where there are insufficient or out-of-service stations.
MIT researchers reveal the kinds of infrastructure improvements that would make the biggest difference in increasing the number of electric cars on the road, a key step toward reducing greenhouse gas emissions from transportation.
Newcastle University scientists have found that 269 airports are at risk of coastal flooding now. A temperature rise of 2C - consistent with the Paris Agreement - would lead to 100 airports being below mean sea level and 364 airports at risk of flooding. If global mean temperature rise exceeds this then as many as 572 airports will be at risk by 2100, leading to major disruptions without appropriate adaptation.
A recent McGill study published in Environmental Science and Technology finds that annual methane emissions from abandoned oil and gas (AOG) wells in Canada and the US have been greatly underestimated - by as much as 150% in Canada, and by 20% in the US. Indeed, the research suggests that methane gas emissions from AOG wells are currently the 10th and 11th largest sources of anthropogenic methane emission in the US and Canada, respectively.
The vital role of ventilation in the spread of COVID-19 has been quantified by researchers, who have found that in poorly-ventilated spaces, the virus spreads further than two metres in seconds, and is far more likely to spread through prolonged talking than through coughing.
New research addresses some of the technical issues that still need to be solved for 3D printed concrete to be strong enough for use in more free-form structures. Researchers found lobster-inspired printing patterns can make 3DCP stronger and help direct the strength where it's needed. And combining the patterns with a concrete mix enhanced with steel fibres can deliver a material that's stronger than traditionally-made concrete.
Supplier selection and pricing format decisions that reflect key characteristics of the project, such as the size of the project, duration, and type of customer, are best at reducing a significant part of cost overruns.
Skoltech researchers have found a way to use chemical sensors and computer vision to determine when grilled chicken is cooked just right. These tools can help restaurants monitor and automate cooking processes in their kitchens, and perhaps one day even end up in your 'smart' oven.
Nagoya University scientists find a rare mineral in nuclear power plant walls, significantly improving their strength following years of full operation.
Researchers have found a simple way to eliminate almost all sequencing errors produced by a widely used portable DNA sequencer (Oxford Nanopore Technologies' MinION device).
