Quantitative analysis of the root posture of mutants with wavy roots.
Quant Plant Biol

Graduate School of Natural Science, Konan University, Kobe 658-8501, Japan.
Plant postures are affected by environmental stimuli. When the gravitational direction changes, the mutants () and () exhibit aberrantly enhanced organ bending. Whether their phenotypes are due to the same mechanism is unknown.

Background: This study aims to provide an estimated dataset of lens zonule balance tension (LZBT) measurements in cataractous lenses among Chinese patients and to conduct a statistical analysis of anterior segment parameters.
Methods: This is a cross-sectional study. We included a total of 833 eyes from 833 Chinese participants aged 23-91 years who underwent cataract surgery.
Oceanic and ionospheric tidal magnetic fields extracted from global geomagnetic observatory data.

Ocean tide generated magnetic fields contain information about changes in ocean heat content and transport that can potentially be retrieved from remotely sensed magnetic data. To provide an important baseline towards developing this potential, tidal signals are extracted from 288 land geomagnetic observatory records having observations within the 50-year time span 1965-2015. The extraction method uses robust iteratively reweighted least squares for a range of models using different predictant and predictor assumptions.

Polymers (Basel)
November 2024
School of Civil Engineering, Anhui Jianzhu University, Hefei 230601, China.
Self-oscillation enables continuous motion by transforming constant external stimuli into mechanical work, eliminating the necessity for supplementary control systems. This holds considerable promise in domains like actuators, wearable devices and biomedicine. In the current study, a novel suspended liquid crystal elastomer (LCEs) ball system consisting of a light-responsive hollow LCE ball and an air blower is constructed.

The sensation of gravity anchors our perception of the environment and is important for navigation. However, the neural circuits that transform gravity into commands for navigation are undefined. We first determined that larval zebrafish (Danio rerio) navigate vertically by maintaining a consistent heading across a series of upward climb or downward dive bouts.
