| Ankle exoskeleton enables faster walking Posted: 23 Apr 2021 06:54 AM PDT In lab tests, researchers found that an optimized ankle exoskeleton system increased participants' walking speed by about 40 percent compared with their regular speed. The researchers hope someday to help restore walking speed in older adults. |
| Quantum steering for more precise measurements Posted: 23 Apr 2021 05:57 AM PDT Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles. |
| Machine learning model generates realistic seismic waveforms Posted: 22 Apr 2021 03:18 PM PDT A new machine-learning model that generates realistic seismic waveforms will reduce manual labor and improve earthquake detection, according to a new study. |
| Scientists glimpse signs of a puzzling state of matter in a superconductor Posted: 22 Apr 2021 06:39 AM PDT High-temperature superconductors are famous for conducting electricity with no loss, but no one knows how they do it. Now scientists have observed the signature of an exotic state of matter called 'pair density waves' in a cuprate superconductor and confirmed that it intertwines with another exotic state -- a step toward understanding how these materials work. |
| Researchers use AI to empower environmental regulators Posted: 19 Apr 2021 03:21 PM PDT Monitoring environmental compliance is a particular challenge for governments in poor countries. A new machine learning approach that uses satellite imagery to pinpoint highly polluting brick kilns in Bangladesh could provide a low-cost solution. |
