Cryptochrome magnetoreception: Time course of photoactivation from non-equilibrium coarse-grained molecular dynamics.

Magnetoreception, the ability to sense magnetic fields, is widespread in animals but remains poorly understood. The leading model links this ability in migratory birds to the photo-activation of the protein cryptochrome. Magnetic information is thought to induce structural changes in cryptochrome via a transient radical pair intermediate.

Closed genomes of commercial inoculant rhizobia provide a blueprint for management of legume inoculation.

Unlabelled: Rhizobia are soil bacteria capable of establishing symbiosis within legume root nodules, where they reduce atmospheric N into ammonia and supply it to the plant for growth. Australian soils often lack rhizobia compatible with introduced agricultural legumes, so inoculation with exotic strains has become a common practice for over 50 years. While extensive research has assessed the N-fixing capabilities of these inoculants, their genomics, taxonomy, and core and accessory gene phylogeny are poorly characterized.

An Information Manifold Perspective for Analyzing Test Data.

Modifications of current psychometric models for analyzing test data are proposed that produce an additive scale measure of information. This information measure is a one-dimensional space curve or curved surface manifold that is invariant across varying manifold indexing systems. The arc length along a curve manifold is used as it is an additive metric having a defined zero and a version of the bit as a unit.

Explanations for higher-than-expected all-cause mortality from April 2021: A scoping review.

Objectives: Many countries have continued to experience a higher-than-expected number of deaths following the peaks in mortality observed in the first year of the Covid-19 pandemic. This review aims to identify the different explanations proposed for sustained higher-than-expected mortality beyond the first pandemic year.

Study Design: Scoping review.
