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

open access: yesMolecular 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 ...

On the significance of polarization charge and isomagnetic surface in the interaction between conducting fluid and magnetic field

open access: yes, 2014
From the frozen-in field lines concept, a highly conducting fluid can move freely along, but not traverse to, magnetic field lines. We discuss this topic and find that in the study of the frozen-in field lines concept, the effects of inductive and ...

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

open access: yesCurrent 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

Hybrid Energy Management for Electric Vehicles: Enhancing Battery Lifespan and Efficiency With Marine Predator Algorithm and Dynamic Floating Mechanism

open access: yesEngineering Reports, Volume 8, Issue 3, March 2026.
An intelligent energy management system (IEMS) optimized by the MPA‐DFM approach dynamically regulates battery power using supercapacitor energy in hybrid electric vehicles. The proposed control strategy minimizes battery stress and power loss, extends lifetime, and ensures real‐time stability across transient and steady‐state driving conditions ...
