Cells can sense 10x farther than expected and it may explain cancer spread
Cells can physically probe their surroundings up to 100 microns ahead — ten times farther than previously thought — by pulling on collagen fibers to gauge what lies beyond their immediate environment. This "depth sensing" plays a direct role in guiding cell migration, with cancer cells using the same mechanism to navigate and spread through tissue. The finding opens a new line of attack for therapies aimed at halting metastasis.

Scientists unlock a powerful new way to turn sunlight into fuel
Researchers have developed a new computational method to fast-track the discovery of materials that convert sunlight into chemical energy, focusing on a class of compounds called polyheptazine imides. By mapping how 53 different metal ions alter the structural and electronic properties of these carbon nitride materials, scientists can now predict top candidates for reactions like hydrogen production and CO2 conversion without exhaustive lab testing. The advance could significantly shorten the timeline for developing next-generation solar fuels.

Scientists create a cancer flashlight that lights up tumors
Researchers have developed a miniaturized antibody that binds to EphA2, a protein common in many cancers, causing tumors to visibly illuminate during PET scans. In animal trials, the technique reliably detected EphA2-positive tumors, offering a potential roadmap for matching patients to targeted therapies. If validated in humans, it could replace slower, more invasive diagnostic methods with a single imaging scan.

Scientists just discovered a tiny signal that volcanoes send before they erupt
Researchers have developed a seismic detection method called "Jerk" that can predict volcanic eruptions with 92% accuracy by picking up subtle ground movements caused by underground magma shifts. The system requires only a single broadband seismometer and, in over a decade of testing at one of the world's most active volcanoes, consistently provided warnings up to eight hours before an eruption. If widely adopted, the low-cost approach could significantly improve evacuation readiness in communities living near active volcanoes.
