Microbial exopolysaccharide production by polyextremophiles in the adaptation to multiple extremes
Polyextremophiles are microorganisms that endure multiple extreme conditions by various adaptation strategies that also include the production of exopolysaccharides (EPSs). This review provides an integrated perspective on EPS biosynthesis, function, and regulation in these organisms, emphasizing their critical role in survival and highlighting their ...

Nicotinamide (NIC) and nicotinic acid (NIA) are proposed as stress signaling compounds in plants. Oxidative stress may lead to single strand breaks (SSB) in DNA, which activate poly(ADP‐ribose) polymerase (PARP). NIC and NIA are then formed from NAD. NIC and NIA can promote epigenetic changes leading to the expression of defense genes specific for the ...

Women Traders of the Viking Age: An Analysis of Grave Goods [PDF]
The image of Viking culture that most of us carry in our heads is largely masculine and testosterone-driven. Where are women in the Scandinavian past? Examining grave goods associated with female burials—including items of personal adornment—this article

An Experiment on the Spectrum [PDF]
IN school and college courses little experimental work is done on the infra-red and ultra-violet parts of the spectrum. The student is, of course, told about these regions, and how they can be detected respectively by the heating and actinic properties of their rays. But he is not allowed to.

In this paper we give some continuity properties of the Weyl spectrum of a continuous linear operator on a Banach space and show that the Weyl's theorem holds for a spectral operator of finite type although the theorem fails for a spectral operator in general.

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

Background Melanoma is one of the most common causes of brain metastases (BM). Despite recent therapeutic advances, survival in patients with brain metastases from melanoma (MBM) is dismal.
