Researchers have discovered evidence that plague may have been involved in epidemics a century before the Black Death, challenging previous assumptions about the disease's arrival in Western Eurasia. The study uses historical sources and genetic analysis to propose a new timeline for the plague's emergence.
A team led by biologist Thomas Mayer found that a small binding-pocket on cyclin B helps regulate the sequence of cell division events. Without this pocket, malformations occur due to incorrect kinase phosphorylation, leading to potential tumours or infertility.
Researchers at Rice University have made a groundbreaking discovery about protein evolution, revealing that pseudogenes can provide clues to the evolutionary journey of proteins. The team found that certain mutations can stabilize the folding of pseudogenes, but also disrupt their biological functions.
Researchers developed a new, accessible, and affordable sequence method using qPCR to identify touch DNA. The study found that male DNA was detected on the female's hand in 50% of trials, indicating secondary transfer, while male DNA on the coffee mug was recorded 27% of time indicating tertiary transfer.
Researchers found that impaired mitochondrial unfolded protein response causes accelerated telomere shortening in both oocytes and somatic cells of aging mice. This study highlights the link between loss of mitochondrial protein homeostasis, infertility, and somatic aging.
A Japanese research team has developed a technique that could lead to a new paradigm for genomic analysis using quantum computers. The breakthrough involves identifying single nucleotides, a crucial step toward creating a molecular sequencer of DNA.
Researchers have successfully visualized the three-dimensional structure of human tRNA splicing endonuclease TSEN, a crucial enzyme in tRNA maturation. The study reveals how TSEN recognizes and excises introns from precursor tRNAs, shedding light on its role in neurodegenerative disorders like pontocerebellar hypoplasia.
Researchers used machine learning to identify 'synthetic extreme' DNA sequences that are active in humans but not fruit flies. These rare sequences have potential practical applications in biotechnology and biomedical research.
DNA recombinations of specific genomic sequences are found in both normal and diseased states, challenging the idea of a single genetic code. The study identified millions of mutations caused by recombination of repeated sequences Alu and L1, which may contribute to cancer and other genetic disorders.
The T2T consortium's completed human genome has shown significant improvements in DNA sequencing accuracy, correcting tens of thousands of errors and revealing millions of genetic variations. This new reference genome can support the analysis of over 200 genes of medical relevance, potentially propelling research into genetic disorders.
A complete, gapless genome sequence has been completed for scientists and physicians, revealing new details about the region around the centromere. The newly sequenced genome provides insights into human genetic variation and may hold clues to the evolution of our ancestors in Africa.
Researchers analyzed DNA from Gibraltar Neanderthal remains found in 1848 and 1926, finding that some sequences were deaminated due to damage, while others showed significant human DNA contamination. The study suggests it is possible to analyze ancient DNA in highly contaminated specimens using a specific preparation method.
The ENCODE project has released a comprehensive guide to its DNA elements database, providing a framework for understanding the human genome's function. The dataset enables scientists to associate single nucleotides with diseases and identify new paths for studying noncoding variants.
A team of researchers discovered a novel RNA gene in the human genome that is rapidly evolving and plays a crucial role in brain development. The gene is transcribed into RNA in the brain and its changes are associated with schizophrenia and other mental disorders.
