Researchers at New York University Abu Dhabi (NYUAD) have developed Spheromatrix, a simple and low-cost technology that enables tumor models to be grown, frozen, and stored for future use in cancer drug testing.

Vanderbilt University and EPB of Chattanooga, home of America’s most comprehensive quantum commercialization infrastructure, today announced plans to establish the Institute for Quantum Innovation, further positioning Chattanooga—and Tennessee—as a national hub for advancing quantum science and technology.  

Like a growing vine, a new robotic gripper can snake around and lift a variety of objects, including a glass vase and a watermelon, offering a gentler approach than conventional gripper designs. A larger version of the robo-tendrils can also safely lift a human out of bed. 

Researchers at Brown University have developed a wearable sensor that uses polarized light to improve the accuracy of photoplethysmography (PPG) signals across different skin tones. Conventional pulse oximeters often underperform on darker skin due to light absorption and scattering by melanin. The new device combines two wavelengths with cross-polarized detection to reduce superficial scattering and enhance deeper vascular signals. In tests with volunteers of light, medium, and brown skin tones, cross-polarization significantly increased perfusion index—a measure of signal strength—compared to co-polarized detection. This approach could help make wearable health technologies more equitable and reliable.
