How travel among synthetic populations reveals gaps in essential services
2024-07-24 23:39:08
Think about your neighborhood. Where are the stores or doctor's offices? How easy is it to access fresh food? Human mobility researchers at the Department of Energy's Oak Ridge National Laboratory are providing information on access to essential services in communities by creating synthetic populations that mirror real neighborhoods and observing how transportation routes around the area support or detract from the residents' quality of life.
Research team designs biomimetic vision system based on praying mantis eyes
2024-07-24 23:39:08
Self-driving cars occasionally crash because their visual systems can't always process static or slow-moving objects in 3D space. In that regard, they're like the monocular vision of many insects, whose compound eyes provide great motion-tracking and a wide field of view but poor depth perception.
Engineering team uses salt for thermal energy storage
2024-07-24 18:26:03
From keeping warm in the winter to doing laundry, heat is crucial to daily life. But as the world grapples with climate change, buildings' increasing energy consumption is a critical problem. Currently, heat is produced by burning fossil fuels such as coal, oil, and gas, but that will need to change as the world shifts to clean energy.
First meltdown-proof nuclear reactor passes loss of cooling test in China
2024-07-24 18:08:01
A team of engineers from Tsinghua University, working at China's high-temperature reactor with a pebble-bed module (HTR-PM), claims that the reactor has passed a critical cooling test. In their study, published in Joule, the group turned off external power to the reactor to test its cooling abilities over two days.
