Julie Blaising, Discovery Project Leader in Immunology at F. Hoffmann-La Roche Ltd, tells us why protein kinases are an effective target for treating many chronic inflammatory disorders.

The different facets of biodiversity

Professor F. Guillaume Blanchet from Université de Sherbrooke explores the various aspects of biodiversity and the challenge involved in monitoring it.
Still image of highly dynamic chromatin (red) interacts with Arc pucta (green). Shown is a small detail of a neuronal nucleus imaged by high-resolution microscopy. Notice how finger-like extensions of the chromatin transiently visit Arc pucta. The movie is sped up 10 times.

Arc: A new target for treating alzheimer’s disease

Antonius M. VanDongen, Associate Professor from Duke University, walks us through Arc, a new target for treating Alzheimer’s disease.

Flipons: The discovery of Z-DNA and soft-wired genomes

Alan Herbert, Founder and President of InsideOutBio, discusses alternative DNA conformations and understanding of their biological functions.
Figure 1. Chemical evolution of type I and type II tRNAs. 3 31 nucleotide minihelices of known sequence were linked to form the 93 nucleotide tRNA precursor, which was processed to type I and type II tRNAs by internal 9 nucleotide deletion(s). The colors are consistent with the model. Molecular graphics were done using ChimeraX

Transfer RNA as a written molecular history of the life transition on earth

Zachary Burton, Ph.D., Professor Emeritus, Department of Biochemistry and Molecular Biology, Michigan State University, reports on tRNA (transfer RNA) as a written molecular history of the pre-life to life transition on Earth ~4 billion years ago.

Artificial intelligence (AI) tools in genetics

Vessela Kristensen and Dag Undlien uncover AI tools in genetics, from variant recognition to clinical implementation.
Figure 1. The reflexivity of AARS genes and the challenges of understanding its origin. The figure illustrates three main challenges. (I) We must construct a bidirectional gene (salmon background) that uses a minimal amino acid alphabet to encode ancestral AARS from Classes I and II on opposite strands. Polypeptide and nucleic acid sequences have directions indicated by (N,C) and (5’,3’). The genes are sequences of codons (colored ellipses) and use only two types of amino acids, A and B. (II) We must show that both coded proteins (I and II) fold into active assignment catalysts that recognize both amino acid and tRNA (colored letters, ellipses in cavities), producing (mostly) aminoacyl-tRNAs with correct amino acids and anticodons. (III) We have to show that the aminoacylated RNAs can assemble onto messenger RNAs (I) and (II), transcribed from the bidirectional gene (reversed dashed arrows).

Structural biology research and the origins of genetic coding

Charles W. Carter, Jr, Department of Biochemistry and Biophysics, University of North Carolina Chapel Hill, reviews the ways that recent research in Structural Biology, Biochemistry, Molecular Biology, and Phylogenetics have opened the origins of genetic coding to experimental study and their important implications.

Flame system: Computerised cognitive assessment for remote brain health monitoring

Monitoring brain health, particularly cognition, in older adults is increasingly recognised as a significant priority for research, healthcare and broader public health. Find out here about the development and validation of the FLAME System, a computerised cognitive assessment for remote brain health monitoring.

Protecting genetic diversity to benefit nature and society

There are three ways that governments and other conservation actors at all levels can monitor and protect genetic diversity, supporting the attainment of biodiversity goals and targets. But first, what is genetic diversity, and is there potential to safeguard it better?

Engineered endosymbionts as novel cancer therapeutics

Satyajit Hari Kulkarni and Christopher H. Contag from the Institute for Quantitative Health Science and Engineering focus on engineered endosymbionts, which they argue is a paradigm shift in anticancer bacteriotherapy toward killing tumors from the inside out.
Figure 1: The central nervous system (CNS) is protected from mechanical injury by the skull (A) and from chemical noxious agents by the blood-brain barrier (B, C). The latter consists of the endothelial barrier in most parts of the CNS (B) and the tanycytic barrier in the hypothalamus (C). We develop gene vectors transducing endothelial cells and tanycytes to treat genetic and non-genetic diseases of the brain.

Bridging brain barriers for gene therapy

Reflecting on the challenges in treating brain diseases, this article explores ways to transduce the blood-brain barrier as well as the critical role of tanycytes as a target for gene therapy vectors.

RNA and DNA flipons in health and disease

Flipons are the next step in DNA research. What they are, their role in DNA and RNA coding, their impact on medical science, and their relation to the immune system are discussed here.
Antibody binding to human cell receptors is a crucial aspect of the immune response and plays a fundamental role in various physiological processes, including immune defense, signaling, and regulation of cellular functions. Antibodies, also known as immunoglobulins, are proteins produced by the immune system in response to the presence of foreign substances, such as pathogens or abnormal cells.

High-resolution snapshots of antibody repertoires as potential correlates of protection

Klaus Eyer from ETH Zurich describes high-resolution snapshots of antibody repertoires as potential correlates of protection.
Figure 1. Elements of the operational RNA code in the tRNA acceptor stem. A. Bases in the tRNA acceptor stem encode two aspects of amino acid physical chemistry—size and polarity—that determine protein folding. B. Acceptor stem bases preceded the anticodon stem-loop and code other properties. C. The oldest parts of Class I and II AARS could already discriminate between both amino acid and RNA substrates (6) .
