A tiny, soft, flexible robot that can crawl through earthquake rubble to find trapped victims or travel inside the human body to deliver medicine may seem like science fiction, but an international team led by researchers at Penn State are pioneering such adaptable robots by integrating flexible electronics with magnetically controlled motion.

Most stars form in clusters, where hundreds to thousands of stars coevolve in proximal environmental conditions that dictate how planetary systems might develop. Nearby massive stars can also contribute intense ionizing radiation, adding external dynamics that form a shell of ionized gas around a protoplanetary disk and emit unique hydrogen recombination spectral lines. Now, a team of astronomers has used archived Atacama Large Millimeter/submillimeter Array (ALMA) observations to identify for the first time the characteristic radio recombination lines associated with these ionized shells surrounding Solar System-sized proplyd disks in the Orion Nebula Cluster, at a distance of 1000 light-years from Earth.

American Sign Language (ASL) recognition systems often struggle with accuracy due to similar gestures, poor image quality and inconsistent lighting. To address this, researchers developed a system that translates gestures into text with 98.2% accuracy, operating in real time under varying conditions. Using a standard webcam and advanced tracking, it offers a scalable solution for real-world use, with MediaPipe tracking 21 keypoints on each hand and YOLOv11 classifying ASL letters precisely.

Research published in ACS Central Science reveals a method that uses pulsed infrared light to identify molecular profiles in blood plasma that could indicate the presence of certain common cancers. In this proof-of-concept study, blood plasma from more than 2,000 people was analyzed to link molecular patterns to lung cancer, extrapolating a potential “cancer fingerprint.”
