Tetraopes Milkweed Beetle Genomes Elucidate the Adaptive Basis of a Temperate Coevolutionary Radiation

Molecular Ecology Resources, Volume 26, Issue 3, April 2026.
ABSTRACT The coevolutionary radiation of 27 species of Tetraopes longhorned beetles and their Asclepias milkweed hosts represents a classic example of adaptive evolution driven by plant chemical defences and herbivore counteradaptations. Investigations to date, however, have focused on a single species, Tetraopes tetrophthalmus, which feeds on the ...

Experiments with eddy currents: The eddy current brake

, 2020
A moderate-cost experimental setup is presented to help students to understand some qualitative and quantitative aspects of eddy currents. The setup operates like an eddy current brake, a device commonly used in heavy vehicles to dissipate kinetic energy

2D Reluctance Model of an Eddy Current Brake with a Magneto Isotropic Material Structure [PDF]

, 2020
This work shows the model of an eddy current brake with an magneto isotropic material structure. For the modelling of the magneto isotropic material structure made of steel posts, a reluctance network is recommended, since a full FEM model would ...

An Optimized Protocol for the Generation of iPSC Lines from Lymphoblastoid Cell Lines Using the Non‐integrative Sendai Virus

Current Protocols, Volume 6, Issue 3, March 2026.
Abstract The choice of cell source for generating induced pluripotent stem cells (iPSCs) is influenced by several factors, including accessibility, reprogramming efficiency, and the invasiveness of the cell collection procedure. Traditional sources such as skin fibroblasts or peripheral blood mononuclear cells often require invasive sampling, which can
