Vision-based structural health monitoring methods offer non-contact, full-field vibration measurement, reducing costs by eliminating the need for physical sensors or surface modifications. However, conventional methods rely on pixel-level data, which is noise-sensitive and exhibits instability. Now, researchers have developed a new virtual sensor framework, where superpixels, instead of pixels, are used as virtual sensors for vibration measurements. This method enhances robustness and accuracy, even in complex environments, without physical markers or contact sensors.

Cilk1 deficiency disrupts normal tooth development by altering primary cilia function and weakening Hedgehog signaling. This reduction triggers extra diastemal teeth, enlarges them under further signaling loss, and can ultimately cause molar fusion. Researchers propose a progressive model linking Hedgehog signaling levels to sequential changes in tooth patterning. The study highlights a previously unknown role for Cilk1 in shaping tooth morphology and improving understanding of developmental dental disorders in humans.

Every week 400,000 people take part in parkruns across the world, with the launch of parkwalkers - to support those walking the 5k routes - shown to have increased the proportion of new female participants and reversed a decline in the average age of new attendees.

PITTSBURGH, Jan. 12, 2026—Scripted television often shows outdated CPR techniques for lay people, potentially fueling misconceptions that could delay bystanders’ lifesaving interventions in the crucial moments after a real-life cardiac arrest. That’s according to University of Pittsburgh School of Public Health and School of Medicine researchers in the first analysis of TV depictions of bystander CPR, published today in Circulation: Population Health and Outcomes.

Shedding pounds almost invariably brings health benefits. But until now, it has been unclear to what extent weight loss also restores the health of the fat tissue itself. A new study from University of Southern Denmark offers insights into the profound changes in fat tissue in response to weight loss.

Japanese researchers have developed a living sensor display that turns engineered skin into a biological monitor, visually indicating internal inflammation without requiring blood sampling.
