New 3D Color Imaging Joins Ultrasound and Photoacoustics to See Inside the Body

Caltech and USC researchers have developed RUS-PAT, a hybrid rotational ultrasound and photoacoustic tomography system that produces fast, three-dimensional color images showing both tissue structure and blood-vessel function. Demonstrations across multiple body regions suggest wide medical potential, including enhanced breast tumor imaging, monitoring nerve damage from diabetes, and concurrent brain structure and blood flow visualization. The technique reaches about 4 cm depth and can complete a scan in under a minute, with ongoing translational development for clinical use.

Portable Ultrasound Linked to First ISS Medical Evacuation

Four astronauts aboard the ISS returned to Earth early due to a medical concern—the first medical evacuation in the station’s 25-year history. NASA has kept details private, but astronaut Mike Fincke said a portable ultrasound helped identify the issue, and the crew was evacuated to Scripps Memorial Hospital for evaluation before being released. The others involved were Zena Cardman, Kimiya Yui, and Oleg Platonov. The incident tests NASA’s emergency response ahead of longer missions like Artemis II, with officials signaling no immediate disclosures about the diagnosis.

Plants click back: moths use plant distress sounds to pick egg sites

Researchers found female moths (Spodoptera littoralis) can hear ultrasonic sounds emitted by drought-stressed plants and use these cues to decide where to lay eggs. In experiments without real plants, moths preferred locations near a stress sound; when healthy plants were present, they avoided the stressed plants, showing context-based decision-making that integrates sound with smell.

Ultrasound Helmet Offers Non-Invasive Parkinson’s Treatment Hope

Researchers from UCL and Oxford have developed a non-invasive ultrasound helmet capable of precisely stimulating deep brain regions, such as the thalamus, without surgery, opening new avenues for neuroscience research and treatment of disorders like Parkinson's disease. The device uses 256 elements to focus ultrasound beams, demonstrated to modulate neural activity in human volunteers, with potential for clinical applications and personalized therapies.
