Salk to Lead $41M ARPA-H Initiative to Make Ultrasound-Controlled Therapies a Reality

Salk Institute researcher Sreekanth Chalasani will lead a multi-institution ARPA-H program, funded up to $41.3 million over about 5.5 years, to advance sonogenetics—the use of ultrasound to control engineered cells—into a clinical therapy by building a protein toolkit, a wearable ultrasound delivery system, and preclinical data across partner sites toward trials, with potential applications such as peripheral neuropathies.

In-Flight Illness on ISS Stumps NASA; Cause Still Unknown

NASA says astronaut Mike Fincke suddenly fell ill aboard the International Space Station during dinner on Jan. 7, could not speak, and although doctors ruled out a heart attack or choking, the cause remains unknown after extensive testing. The 20-minute episode prompted NASA’s first medical evacuation and the early return of two crewmates, with ultrasound aiding the response. NASA is reviewing medical records from other astronauts for possible patterns while considering whether long exposure to weightlessness could be a factor.

Ultrasound Simulator Aims to Fast-Track Endometriosis Diagnosis

Endometriosis affects about 190 million people worldwide and is often diagnosed only after invasive surgery. A new ultrasound-based training simulator from Surgical Science teaches clinicians to use the sliding sign to detect adhesions and endometriosis, potentially shortening diagnostic delays and reducing unnecessary procedures. Early tests found 92% of trained clinicians could recognize signs of deep infiltrating endometriosis on ultrasound, with confidence up 150%, though ultrasound has limits compared with MRI/CT and some lesions remain hard to detect. If adopted, the simulator could standardize education and speed up access to relief for many patients.

Ultrasound Simulator Trains Clinicians to Detect Hidden Endometriosis

A Swedish company Surgical Science released an ultrasound-based Endometriosis Simulation Module to train clinicians to recognize deep infiltrating endometriosis by detecting adhesions (sliding sign), aiming to speed diagnosis and reduce the need for invasive exploratory surgery; tests showed 92% recognition of signs and about a 150% boost in clinician confidence, though the tool cannot detect all adhesions and some cases still require surgery; endometriosis affects roughly 190 million people worldwide.

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.

Ultrasound Helps ISS Medical Evacuation Highlighting Deep-Space Readiness

Four astronauts were flown back to Earth from the International Space Station after a medical concern, with NASA keeping details private. Public remarks from Mike Fincke revealed a portable ultrasound was instrumental in diagnosing the issue during the emergency, underscoring the crew’s preparedness as NASA eye’s longer missions such as Artemis II.

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

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.
