A team at National Institute of Informatics, Japan and University of Waterloo developed a method that automatically transforms models of controller software into models that satisfy safety requirements even when uncertainty in sensing the state of the environment. In addition, the method generates formulas that represent the degree of uncertainty that the controller software can tolerate. The method can be applied to various controller systems that interact with the external environment, including autonomous vehicles.

Scientists from the National University of Science and Technology "MISiS" (NUST MISIS) in cooperation with their colleagues from the Siberian Federal University and the Research and Production Centre of Magnetic Hydrodynamics (Krasnoyarsk) have developed a technology for producing a unique heat-resistant aluminium alloy with improved durability. According to the researchers, this new alloy could replace more expensive and heavier copper conductors in aircraft and high-speed rail transport. The study results were published in an interdisciplinary, peer-reviewed journal, the Materials Letters.
An algorithm developed at Caltech lets machines teach themselves how to recognize landscapes, even amid the changing seasons.
An incredibly light new material that can reduce aircraft engine noise and improve passenger comfort has been developed at the University of Bath. The graphene oxide-polyvinyl alcohol aerogel weighs just 2.1kg per cubic metre, making it the lightest sound insulation ever manufactured.
Researchers at the University of Houston, in collaboration with Rice University, published a paper detailing how to improve energy density in a novel electric vehicle battery - a step toward a more cost-effective, easily recycled battery that would allow EVs to travel farther and charge faster at a low cost.
An innovative underwater robot known as Mesobot is providing researchers with deeper insight into the vast mid-ocean region known as the "twilight zone." Capable of tracking and recording high-resolution images of slow-moving and fragile zooplankton, gelatinous animals, and particles, Mesobot greatly expands scientists' ability to observe creatures in their mesopelagic habitat with minimal disturbance.
Optical cloaking allows objects to be hidden in plain sight by guiding light around anything placed inside the cloak. While cloaking has been popularized in fiction, researchers in recent years have started realizing cloaks that shield objects from view by controlling the flow of electromagnetic radiation around them. In Journal of Applied Physics, researchers examined recent progress of developing invisibility cloaks that function in natural incoherent light and can be realized using standard optical components.
Researchers at the University of Colorado Boulder are addressing one aspect of creating fuel cells that can convert hydrogen and oxygen safely into water by developing new computational tools and models needed to better understand and manage the conversion process.
An international team of collaborators has made the first direct observation of the anionic redox reaction in a lithium-rich battery material. The research opens up pathways for improving existing battery cathodes--and designing new ones.
