Not Aging but Calorie Restriction Strongly Affects Protein Oxidation in Heart and Brain Mitochondria

open access: yesAging Cell, Volume 25, Issue 1, January 2026.
Our comprehensive proteomic analysis reveals that calorie restriction (CR), not aging, is the primary driver of mitochondrial protein oxidation, with striking tissue‐specific effects. While CR reduces oxidation in the heart, it exerts a dual and opposing role within the cerebrum. ABSTRACT Aging is an inevitable consequence for all organisms.

The Samples and Binary Fractions of Red Supergiants in M31 and M33 by the HST Observations

open access: yesThe Astrophysical Journal
The binarity of red supergiants (RSGs) influences their evolution and the fate of supernovae. We investigate the binary fraction of RSGs in the Andromeda galaxy (M31) and Triangulum galaxy (M33) using photometry from the Hubble Space Telescope (HST ...

Can unsupervised machine learning gain new insights into urodynamic pressure flow pattern analysis?

open access: yesBJU International, Volume 137, Issue 1, Page 112-119, January 2026.
Objectives To explore the use of unsupervised machine learning (UML) to analyse segments of the pressure flow study (PFS) curve after maximum flow, and subsequently to analyse the urodynamic and patient characteristics of men in the detected clusters. Subjects and Methods In this study, we considered 1650 PFSs of men with lower urinary tract symptoms ...

Synthetic trap‐peptides identify a TOM complex phosphatase – PP2A dephosphorylates Tom6

open access: yesThe FEBS Journal, Volume 293, Issue 1, Page 271-294, January 2026.
Synthetic trap‐peptides facilitate the identification of complete holoenzymes that bind to the target sequence remarkably close to the phosphorylation site. PP4 bound to, but did not dephosphorylate, the peptide substrate taken from yeast Tom6 pSer16, showing that proximity alone does not induce phosphatase activity.

Unveiling the Proteomic Landscape of Extracellular Vesicles: Implications for Neurodegeneration and Neuroprotection

open access: yesJournal of Neurochemistry, Volume 170, Issue 1, January 2026.
Extracellular vesicles (EVs) are tiny, membrane‐covered packets that cells naturally release to send molecular information to one another. In the brain, they function as couriers that move proteins, lipids, and other signals between neurons, glial cells, and the blood–brain barrier.

Long‐term assessment of the Moss Layer Transfer Technique for the restoration of Sphagnum‐dominated peatlands

open access: yesRestoration Ecology, Volume 34, Issue 1, January 2026.
Abstract Introduction Peatlands are crucial for carbon storage and biodiversity but face increasing human degradation. The Moss Layer Transfer Technique (MLTT) has emerged as an effective method for restoring Sphagnum‐dominated vegetation in post‐extracted horticultural peatlands. Objectives This study evaluates vegetation restoration trajectories over
