Random robots are more reliable      (via sciencedaily.com)     Original source 

New algorithm encourages robots to move more randomly to collect more diverse data for learning. In tests, robots started with no knowledge and then learned and correctly performed tasks within a single attempt. New model could improve safety and practicality of self-driving cars, delivery drones and more.

This highly reflective black paint makes objects more visible to autonomous cars      (via sciencedaily.com)     Original source 

Driving at night might be a scary challenge for a new driver, but with hours of practice it soon becomes second nature. For self-driving cars, however, practice may not be enough because the lidar sensors that often act as these vehicles' 'eyes' have difficulty detecting dark-colored objects. New research describes a highly reflective black paint that could help these cars see dark objects and make autonomous driving safer.

Details of hurricane Ian's aftermath captured with new remote sensing method      (via sciencedaily.com)     Original source 

Using aerial imagery data and LiDAR, a study remotely identified the hardest-hit areas of Southwest Florida's Estero Island in the aftermath of Hurricane Ian. Researchers estimated the extent of structural damage and compared pre- and post-storm beach structural changes. They identified 2,427 structures that were impacted. The value of the heavily damaged structures was estimated at more than $200 million. The study has applied an advanced multi-faceted approach that links damage assessment to post-storm change in the structure of barrier islands.

Warming Arctic reduces dust levels in parts of the planet      (via sciencedaily.com)     Original source 

Dust can have a huge impact on local air quality, food security, energy supply and public health. Previous studies have found that dust levels are decreasing across India, particularly northern India, the Persian Gulf Coast and much of the Middle East, but the reason has remained unclear. Researchers found that the decrease in dust can be attributed to the Arctic warming much faster than the rest of the planet, a phenomenon known as Arctic amplification. This process destabilizes the jet stream and changes storm tracks and wind patterns over the major sources of dust in West and South Asia.

Hurricanes jeopardize carbon-storing New England forests      (via sciencedaily.com)     Original source 

Many American companies are relying on carbon offsets to reduce their carbon footprint, especially those who have pledged to achieve 'net-zero emissions.' Sequestering carbon in forests is an example of a nature-based solution that is being used to address climate change, but a new study suggests that hurricanes could pose a risk. The results show that a single hurricane may wipe out 5% to 10% of total above-ground forest carbon, through tree damage, in New England.

Magnetic cilia -- artificial hairs whose movement is powered by embedded magnetic particles -- have been around for a while, and are of interest for applications in soft robotics, transporting objects and mixing liquids. However, existing magnetic cilia move in a fixed way. Researchers have now demonstrated a technique for creating magnetic cilia that can be 'reprogrammed,' changing their magnetic properties at room temperature to change the motion of the cilia as needed.

Shoreline model predicts long-term future of storm protection and sea-level rise      (via sciencedaily.com)     Original source 

Researchers have created a coastal evolution model to analyze how coastal management activities on barrier islands, meant to adapt to sea-level rise, can disrupt natural processes that are keeping the barrier islands above water. Replenishing beaches and clearing over-washed roads may not be the best long term strategy.

Marginalized communities developed 'disaster subculture' when living through extreme climate events      (via sciencedaily.com)     Original source 

An assistant professor conducted a study in which he lived among one of the poorest, most marginalized communities in Seoul, South Korea. In the ethnographic study, he asked residents how they dealt with extreme heat. He found they tended to accept the conditions, stating there was not much that could be done. That shows people accepted extreme climate events, despite evidence showing this should not be normal, which bodes the argument social work as a field has much to do to help address climate emergencies.

'Sunny day flooding' increases fecal contamination of coastal waters      (via sciencedaily.com)     Original source 

A new study finds that 'sunny day flooding,' which occurs during high tides, increases the levels of fecal bacteria in coastal waters. While the elevated bacteria levels in the coastal waters tend to dissipate quickly, the findings suggest policymakers and public health officials should be aware of potential risks associated with tidal flooding.
