UC San Diego engineers created a soft, wearable ultrasound patch that can continuously monitor a fetus for hours at a time, even during constant movement. The technology could help doctors detect complications earlier in high-risk pregnancies and expand access to prenatal care in low-resource areas.

Researchers at Nanjing University developed platinum(IV)-antibody conjugates that enhance tumor immunogenicity without relying on strong cancer cell killing. The targeted system delivers low-dose platinum selectively to tumors, increasing MHC-I expression and improving immune recognition while reducing systemic toxicity. In mouse models, the strategy significantly enhanced the efficacy of anti-PD-1 immunotherapy.

People often say that seeking psychiatric care can feel intimidating. Patients may feel burdened when they first open up about their emotional distress, while medical staff must accurately understand a patient’s extensive history and symptoms within limited consultation time. Korean researchers have developed artificial intelligence (AI) technology that supports the initial psychiatric interview process, the first step in psychiatric care.

Lakes play a vital filtering role in the ecosystem: they remove excess nitrogen from the water. An international research team led by the University of Basel and Eawag has now shown that climate change could weaken this natural purification process. This would have consequences extending all the way to coastal marine ecosystems.

Researchers at the University of New South Wales and Monash University in Australia have developed a new method for covert communications. By taking advantage of the phenomena of “negative luminescence”, the opposite of the electroluminescence of conventional visible light emitting diodes (LEDs), they demonstrate that a data signal can be perfectly hidden in the thermal background, with only an outside observer with the same technology able to observe that a message was sent at all.

Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a tiny seed-sized robot that can navigate across soft and uneven surfaces to perform five surgical functions wirelessly, paving the way for developing robots to make surgeries and medical treatments more precise. The miniature robot, measuring just 4.4 mm in length and controlled by weak magnetic fields, can move, cut biological tissues, release drugs, grip and store tissue samples, or generate heat remotely at any one time. It takes under a second to switch between these functions.
