A team at South Korea’s Gwangju Institute of Science and Technology (GIST) developed a new technique to easily visualize viruses using an optical microscope.

Bridge to Life Ltd. has won FDA breakthrough device designation for its Lifecradle Heart Preservation Transport System enabling clinicians to affordably implement hypothermic oxygenated perfusion of heart grafts during organ transport. Lifecradle employs a “plug-and-play” design to differentiate it from historic static cold storage but also from “normothermic” preservation which provides oxygen delivery at near physiologic temperatures.

Four months after debuting W1 health watch at Arab Health 2022, Masimo Corp. reported a limited release of the consumer version of the device in the U.S. to 10,000 users on a first come-first served basis. The wrist-worn device, which measures oxygen saturation, pulse rate, perfusion index, pleth variability index and respiration rate, also counts steps and detects falls.

Hello Heart Inc. more than doubled its fundraising to date with a $70 million series D financing round showing heart-warming support from investors for its digital therapeutic solution. Growth equity firm Stripes led the round, which brought the heart-focused digital therapeutic company’s total raised to date to more than $138 million.

Researchers have uncovered a new pathway via which cancer cells evade the effects of radiation by deploying self-inflicted – but reversible – DNA breaks to stop the cell cycle and ensure their survival. The lesions are caused by caspase-activated DNase (CAD), an enzyme involved in DNA fragmentation during cell death. In response to radiation, tumor cells activate CAD, causing genome-wide DNA breaks at sites involved in DNA repair.
