  1. Financial structure of early childhood education requires overhaul to make it accessible and affordable, report says
    High-quality early care and education (ECE) is critical to positive child development and has the potential to generate economic returns, but the current financing structure of ECE leaves many children without access to high-quality services and does little to strengthen the ECE workforce, says a new report from the National Academies of Sciences, Engineering, and Medicine.
  2. Short-term use of IV devices is common -- and risky -- study shows
    Many hospital patients get medicine or nutrition delivered straight into their bloodstream through a tiny device called a PICC. In just a decade, it's become the go-to device for intravenous care. But a new study finds that one in every four times a PICC gets inserted, the patient didn't need it long enough to justify the risks it can pose. And nearly one in ten of those patients suffered a complication linked to the device.
  3. Young children use physics, not previous rewards, to learn about tools
    Children as young as seven apply basic laws of physics to problem-solving, rather than learning from what has previously been rewarded, suggests new research.
  4. Metalens combined with an artificial muscle
    Inspired by the human eye, researchers have developed an adaptive metalens that is essentially a flat, electronically controlled artificial eye. The adaptive metalens simultaneously controls for three of the major contributors to blurry images: focus, astigmatism, and image shift.
  5. Charging ahead to higher energy batteries
    Researchers have developed a new way to improve lithium ion battery efficiency. Through the growth of a cubic crystal layer, the scientists have created a thin and dense connecting layer between the electrodes of the battery.
