Climate change could hasten deterioration of US bridge infrastructure
Hussam Mahmoud is studying the toll climate change may take on aging US infrastructure, which includes over 600,000 bridges. Now, he is co-author of a new study linking the potential impacts of climate change with the structural integrity of thousands of bridges transecting America's highways and towns. Mahmoud's analysis demonstrates a need to rethink the nation's priority order of bridge repair, as climate change looms and infrastructure funding remains limited. (2019-10-23)

Predicting the impact of climate change on bridge safety
Climate change will increase the frequency and intensity of natural hazards like flooding. In turn, floodwaters erode a bridge's foundation, creating scour holes that compromise the integrity of the structure. But to date, it's been possible to quantify that scour risk. A new model developed by civil engineering researchers at Lehigh University takes a holistic approach combining climatology, hydrology, structural engineering, and risk assessment to determine the effects of climate change on bridges.

The brain inspires a new type of artificial intelligence
Using advanced experiments on neuronal cultures and large scale simulations, scientists at Bar-Ilan University have demonstrated a new type of ultrafast artifical intelligence algorithms -- based on the very slow brain dynamics -- which outperform learning rates achieved to date by state-of-the-art learning algorithms. In an article in Scientific Reports, the researchers rebuild the bridge between neuroscience and advanced artificial intelligence algorithms that has been left virtually useless for almost 70 years.

Scientists reveal close connections between the Northern Hemisphere mid-high latitudes and East Asia
In recent years, increasingly more observational and simulation evidence shows that the mid-high latitude climate variability has an important impact on the East Asian monsoon climate, and its impact is as significant as the tropical climate variability, which has been of more concern in previous studies. Among the evidence, Chinese scientists have produced systematic research results and played a crucial role in promoting the development of climate research in East Asia. (2019-07-09)

New high-definition satellite radar can detect bridges at risk of collapse from space

A new way to see stress -- using supercomputers
Supercomputer simulations show that at the atomic level, material stress doesn't behave symmetrically. Widely-used atomic stress formulae significantly underestimate stress near stress concentrators such as dislocation core, crack tip, or interface, in a material under deformation. NSF-funded XSEDE-allocated Jetstream and Comet supercomputers simulate force interactions of Lennard-Jones perfect single crystal of 240,000 atoms. Study findings could help scientists design new materials such as glass or metal that doesn't ice up. (2018-11-30)
