3D-Printed ATLAS Platform Helps Scientists Probe How Cancer Spreads
Rice University bioengineers have created a scalable 3D-printed platform that mass-produces realistic cancer cell clusters, opening a new window into how tumors survive in the bloodstream and spread through the body. The work could guide future drugs that disrupt metastasis before it takes hold.

Continuous Wearable Monitoring Cut Dangerous Low-Oxygen Time After Surgery
A yearlong trial at Atrium Health Wake Forest Baptist found that surgical patients wearing continuous monitors spent far less time with dangerously low oxygen levels than those checked only every few hours. The findings suggest a practical way to catch complications earlier and make hospital recovery safer.

Sleep Apps Can Improve Rest — But May Worsen Insomnia, Study Finds
A new Norwegian study suggests sleep-tracking apps can be a useful tool for some users but may backfire for people with insomnia, fueling stress and sleepless nights. Researchers say it is crucial to understand how these apps work — and when to turn them off.

Scientists Use Sound Waves to Remotely Switch Material Stiffness
A team led by UC San Diego has shown that sound waves can act like a remote control for a material’s stiffness by moving tiny internal features called kinks. The work hints at future protective gear, soft robots and implants that can adapt on demand.

Roadside ‘EyeDAR’ Sensors Give Self-Driving Cars New Vision
A new radar “tag” called EyeDAR could give self-driving cars an extra set of eyes by turning streetlights and stop signs into smart, talking sensors. Rice University engineers say the low-power devices may help autonomous vehicles see around corners, through bad weather and beyond their own blind spots.
