A view of the evolution of a coronal mass ejection and the associated wave trains at high spatial and temporal resolution

Astronomy & Astrophysics
Context. The study of the kinematic and dynamic evolution of fast, eruptive events from the middle to the high solar corona is one of the primary scientific objectives of the Metis coronagraph on board the Solar Orbiter satellite. During the spacecraft’s

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Solar prominences

, 2008
International audienceSolar filaments (or prominences) are magnetic structures in the corona. They can be represented by twisted flux ropes in a bipolar magnetic environment.

A comprehensive examination of camel (Camelus Dromedaries) otic prominence through morphological and CT imaging studies

Journal of Basic and Applied Zoology
Background This study explored the morphological anatomy of otic prominences in camels using advanced computed tomography (CT). Nine adult cadaver camel heads underwent CT scanning to generate detailed images of the otic prominences, mastoid process ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics

FEBS Letters, EarlyView.
Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...

Slingshot prominences : a hidden mass loss mechanism [PDF]

, 2021
Funding: The authors acknowledge support from STFC consolidated grant number ST/R000824/1.Whilst "slingshot" prominences have been observed on M-dwarfs, most if not all theoretical studies have focused on solar-like stars.

The role of ambipolar heating in the energy balance of solar prominences

Astronomy & Astrophysics
Solar prominence threads are typically located around magnetic dips, where cold and dense plasma is suspended against gravity in the hot corona due to the upward magnetic force.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
