text: Molecular motors are essential to the living, generating fluctuations that
boost transport and assist assembly. Active colloids, that consume energy to move,
hold similar potential for man-made materials controlled by forces generated from
within. Yet, their use as a powerhouse in materials science lacks. Here we show
a massive acceleration of the annealing of a monolayer of passive beads by moderate
addition of self-propelled microparticles. We rationalize our observations with
a model of collisions that drive active fluctuations and activate the annealing.
The experiment is quantitatively compared with Brownian dynamic simulations that
further unveil a dynamical transition in the mechanism of annealing. Active dopants
travel uniformly in the system or co-localize at the grain boundaries as a result
of the persistence of their motion. Our findings uncover the potential of internal
activity to control materials and lay the groundwork for the rise of materials
science beyond equilibrium.

text: Epigenetic reprogramming is required for proper regulation of gene expression
in eukaryotic organisms. In Arabidopsis, active DNA demethylation is crucial for
seed viability, pollen function, and successful reproduction. The DEMETER (DME)
DNA glycosylase initiates localized DNA demethylation in vegetative and central
cells, so-called companion cells that are adjacent to sperm and egg gametes, respectively.
In rice, the central cell genome displays local DNA hypomethylation, suggesting
that active DNA demethylation also occurs in rice; however, the enzyme responsible
for this process is unknown. One candidate is the rice REPRESSOR OF SILENCING
1a (ROS1a) gene, which is related to DME and is essential for rice seed viability
and pollen function. Here, we report genome-wide analyses of DNA methylation in
wild-type and ros1a mutant sperm and vegetative cells. We find that the rice vegetative
cell genome is locally hypomethylated compared with sperm by a process that requires
ROS1a activity. We show that many ROS1a target sequences in the vegetative cell
are hypomethylated in the rice central cell, suggesting that ROS1a also demethylates
the central cell genome. Similar to Arabidopsis, we show that sperm non-CG methylation
is indirectly promoted by DNA demethylation in the vegetative cell. These results
reveal that DNA glycosylase-mediated DNA demethylation processes are conserved
in Arabidopsis and rice, plant species that diverged 150 million years ago. Finally,
although global non-CG methylation levels of sperm and egg differ, the maternal
and paternal embryo genomes show similar non-CG methylation levels, suggesting
that rice gamete genomes undergo dynamic DNA methylation reprogramming after cell
fusion.

text: A central goal of computational physics and chemistry is to predict material
properties by using first-principles methods based on the fundamental laws of
quantum mechanics. However, the high computational costs of these methods typically
prevent rigorous predictions of macroscopic quantities at finite temperatures,
such as heat capacity, density, and chemical potential. Here, we enable such predictions
by marrying advanced free-energy methods with data-driven machine-learning interatomic
potentials. We show that, for the ubiquitous and technologically essential system
of water, a first-principles thermodynamic description not only leads to excellent
agreement with experiments, but also reveals the crucial role of nuclear quantum
fluctuations in modulating the thermodynamic stabilities of different phases of
water.

text: Glyphosate (N-phosphonomethyl glycine) and its commercial herbicide formulations
have been shown to exert toxicity via various mechanisms. It has been asserted
that glyphosate substitutes for glycine in polypeptide chains leading to protein
misfolding and toxicity. However, as no direct evidence exists for glycine to
glyphosate substitution in proteins, including in mammalian organisms, we tested
this claim by conducting a proteomics analysis of MDA-MB-231 human breast cancer
cells grown in the presence of 100 mg/L glyphosate for 6 days. Protein extracts
from three treated and three untreated cell cultures were analysed as one TMT-6plex
labelled sample, to highlight a specific pattern (+/+/+/−/−/−) of reporter intensities
for peptides bearing true glyphosate treatment induced-post translational modifications
as well as allowing an investigation of the total proteome.
