Research from the University of Gothenburg estimates climate change to decrease the number of days with temperatures below zero degrees in West Midlands. It will also reduce the number of traffic accidents - and the need for winter road maintenance may decrease by almost 40 percent.
A study lead by Anna Andersson explores the link between winter road conditions and traffic accidents in Sweden and in West Midlands, UK. Andersson considers four different types of slipperiness, from snowy and icy roads to above-zero temperatures with slippery ice patches, and how climate change may affect these conditions in the next 90 years.
Andersson concludes that by the 2080s, West Midlands will have an average of 28 frosty days per year compared to today's 69. Theoretically, this will reduce the number of traffic accidents by 43%. It may also lead to a decrease in the need for winter road maintenance by 38%.
However, the total number of accidents is not determined entirely by the number of below-zero days per year, since the road conditions are in fact the most dangerous at temperatures close to zero.
'Roads can still be dangerous when the temperature rises above zero. When we don't think it's slippery, and even the thermometer tells us it's not slippery, we tend to drive as if it were summer roads. But temperatures around zero often lead to slippery spots, increasing the risk for accidents', says Andersson, at the Department of Earth Sciences.For more information:

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
