Department of Molecular Genetics, Weizmann Institute of Science, Rehovot, 76100, Israel. Electronic address:
Adaptation to environmental conditions occurs over diverse evolutionary timescales. In multi-cellular organisms, adaptive traits are often studied in tissues/organs relevant to the environmental challenge. We argue for the importance of an underappreciated layer of evolutionary adaptation manifesting at the cellular level.

The cell nuclei of Ophisthokonts, the eukaryotic supergroup defined by fungi and metazoans, is remarkable in the constancy of their double-membraned structure in both somatic and germ cells. Such remarkable structural conservation underscores common and ancient evolutionary origins. Yet, the dynamics of disassembly and reassembly displayed by Ophisthokont nuclei vary extensively.

Introduction: Lonicera caerulea L. (blue honeysuckle) is a noteworthy fleshy-fruited tree and a prominent medicinal plant, which possesses notable characteristics such as exceptional resilience to winter conditions and early maturation, and the richest source of functional anthocyanins, particularly cyanidin-3-glucoside. The molecular mechanisms responsible for its freezing tolerance and anthocyanin biosynthesis remain largely unknown.

December 2024
Department of Biochemistry, Kampala International University-Western Campus, Ishaka, Uganda.
Aptamers, single-stranded nucleic acids that bind to specific targets with high affinity and specificity, hold significant promise in various biomedical and biotechnological applications. The traditional method of aptamer selection, SELEX (Systematic Evolution of Ligands by EXponential Enrichment) takes a lot of work and time. Recent advancements in computational methods have revolutionized aptamer design, offering efficient and effective alternatives.
