  • A route for avoiding defects during additive manufacturing November 27, 2020
    Research reveals how pores form during metals additive manufacturing and become defects trapped in solidifying metal. The practical value of this research is that it can inform industry on how to predict and improve 3D printing processes.
  • CRISPRi screens reveal sources of metabolic robustness in E. coli November 24, 2020
    Metabolic robustness, the ability of a metabolic system to buffer changes in its environment, is not always a welcome feature for microbiologists: it interferes with metabolic engineering or prevents that antibiotics kill bacteria. Therefore it is important to understand the mechanisms that enable metabolic robustness. A massively parallel CRISPRi screen demonstrated that E. colimetabolism is […]
  • More skin-like, electronic skin that can feel November 24, 2020
    A research team has developed a multimodal ion-electronic skin that distinguishes temperature from mechanical stimuli. This skin can detect various movements and is applicable in fields including humanoid skin and temperature sensors.
  • AI system discovers useful new material November 24, 2020
    When the words 'artificial intelligence' (AI) come to mind, your first thoughts may be of super-smart computers, or robots that perform tasks without needing any help from humans. Now, a multi-institutional team has accomplished something not too far off: They developed an AI algorithm called CAMEO that discovered a potentially useful new material without requiring […]
  • Supersized wind turbines generate clean energy--and surprising physics November 23, 2020
    As wind energy scales up, researchers study the fluid dynamics challenges.
  • The science of windy cities November 23, 2020
    Researchers model urban airflows to help improve the design of drones, skyscrapers, and natural ventilation systems.
  • Lab closed? Head to the kitchen November 23, 2020
    Studies explore fluids in pancakes, beer, and the kitchen sink.
  • Optimizing complex modeling processes through machine learning technologies November 23, 2020
    Engineering a spaceship is as difficult as it sounds. Modeling plays a large role in the time and effort it takes to create spaceships and other complex engineering systems. It requires extensive physics calculations, sifting through a multitude of different models and tribal knowledge to determine singular parts of a system's design.
  • Showing robots how to drive a car...in just a few easy lessons November 19, 2020
    Researchers have designed a system that lets robots autonomously learn complicated tasks from a very small number of demonstrations -- even imperfect ones. While current state-of-art methods need at least 100 demonstrations to nail a specific task, this new method allows robots to learn from only a handful of demonstrations.
  • New tool to combat terrorism November 19, 2020
    Forensic science experts are refining an innovative counter-terrorism technique that checks for environmental DNA in the dust on clothing, baggage, shoes or even a passport.
