  1. Mathematical tool helps calculate properties of quantum materials more quickly

    Many quantum materials have been nearly impossible to simulate mathematically because the computing time required is too long. Now engineers have demonstrated a way to considerably reduce the computing time. This could accelerate the development of materials for energy-efficient IT technologies of the future.
  2. Computer scientists set benchmarks to optimize quantum computer performance

    Computer scientists have shown that existing compilers, which tell quantum computers how to use their circuits to execute quantum programs, inhibit the computers' ability to achieve optimal performance. Specifically, their research has revealed that improving quantum compilation design could help achieve computation speeds up to 45 times faster than currently demonstrated.
  3. Versatile new material family could build realistic prosthetics, futuristic army platforms

    Nature's blueprint for the human limb is a carefully layered structure with stiff bone wrapped in layers of different soft tissue, like muscle and skin, all bound to each other perfectly. Achieving this kind of sophistication using synthetic materials to build biologically inspired robotic parts or multicomponent, complex machines has been an engineering challenge.
  4. AI software enables real-time 3D printing quality assessment

    Researchers have developed artificial intelligence software for powder bed 3D printers that assesses the quality of parts in real time, without the need for expensive characterization equipment.
  5. A light bright and tiny: Scientists build a better nanoscale LED

    A new design for light-emitting diodes achieves a dramatic increase in brightness as well as the ability to create laser light -- characteristics that could make it valuable in a range of applications. The device shows an increase in brightness of 100 to 1,000 times over conventional submicron-sized LED designs.
  6. One step closer to bomb-sniffing cyborg locusts

    Research has determined that locusts can smell explosives and determine where the smells originated -- an important step in engineering cyborg bomb-sniffing locusts.
  7. An AI algorithm to help identify homeless youth at risk of substance abuse

    While many programs and initiatives have been implemented to address the prevalence of substance abuse among homeless youth in the United States, they don't always include data-driven insights about environmental and psychological factors that could contribute to an individual's likelihood of developing a substance use disorder. Now, an artificial intelligence (AI) algorithm could help predict susceptibility to substance use disorder among young homeless individuals, and suggest personalized rehabilitation programs for highly susceptible homeless youth.
  8. Linking sight and movement

    Researchers found that image-processing circuits in the primary visual cortex not only are more active when animals move freely, but that they receive signals from a movement-controlling region of the brain that is independent from the region that processes what the animal is looking at.
  9. This online calculator can predict your stroke risk

    Doctors can predict patients' stroke risk by using an online tool that measures the severity of their metabolic syndrome, a conglomeration of conditions that includes high blood pressure, abnormal cholesterol levels and excess body fat.
  10. Many medical 'rainy day' accounts aren't getting opened or filled

    One-third of the people who could benefit from a special type of savings account to cushion the blow of their health plan deductible aren't doing so, a new study finds. And even among people who do open a health savings account, half haven't put any money into it in the past year. This means they may be missing a chance to avoid taxes on money they can use to pay for their health insurance deductible and other costs.
