Human Atlas of Tooth Decay Progression: Identification of Cellular Mechanisms Driving the Switch from Dental Pulp Repair Toward Irreversible Pulpitis

Advanced Science, Volume 13, Issue 8, 9 February 2026.
Tooth decay progression transforms the dental pulp response from repair to fibrosis. At early stages, stromal cells reprogram to repair the extra cellular matrix (ECM), blood vessels, and nerves, remodel and grow, keeping repair possible. In advanced decay, hypoxia, and vessel regression, in complement with an immune switch, fuel nerve degeneration and

Improved YOLOv5 for Efficient Elimination of Unwanted Video Frames From High‐Speed Video Arrays Capturing Bat's Kinematics

Applied AI Letters, Volume 7, Issue 1, February 2026.
Deep learning pipeline developed to filter high‐speed bat flight recordings captured inside a custom flight tunnel. ABSTRACT This research aims to investigate the flying kinematics of bats, drawing inspiration from nature to benefit humans in achieving vision‐independent flights. The project uses 50 cameras mounted inside a specially designed tunnel to

Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior

Advanced Physics Research, Volume 5, Issue 2, February 2026.
Diel vertical migration hides an unexpected twist: Phytoplankton quietly engineer their local pH landscape, splitting into behaviorally distinct sub‐groups which stay separated even in identical conditions. Circadian pH changes, occuring over the course of a day, reshape their gravitactic behavior and physiological functions in ways scientists have ...

Evaluating the Risk of Collision of Seals Swimming Within Metres of Operating Tidal Turbines

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT We used imaging sonar to continuously monitor wildlife at an operational tidal turbine in the Pentland Firth, Scotland, between May 2022 and June 2023. Of 704 detected seal tracks, 347 occurred during turbine operation and 122 of these were detected directly upstream of the rotating blades in the horizontal plane.

Systematically Reviewing the Rigour of Immersive Virtual Reality Research in STEM Education: A Deep Dive Into Threats to Internal Validity

Journal of Computer Assisted Learning, Volume 42, Issue 1, February 2026.
ABSTRACT Background There have been many initiatives focused on implementing IVR in the classroom to either replace or supplement conventional instruction. The efficacy of these initiatives is often informed by IVR media comparison studies that examine the learning outcomes of students who learn academic content in IVR versus conventional media ...
