include spermidine, spermine, and putrescine. These molecules participate in many cellular processes. They interact with DNA, RNA, and proteins, helping regulate gene activity, cell growth, and stress responses. Previous research has shown that...

now points toward an unexpected origin, the gut. In a comprehensive international study, researchers analyzed microbial DNA from hundreds of individuals across multiple countries. Their findings suggest that disruptions in gut bacteria may quietly...

treatment. Vitamin B12 and folate deficiency as the primary drivers Both vitamin B12 and folate (B9) are essential for normal DNA synthesis in red blood cell precursors. When either nutrient is lacking, cells divide improperly and grow oversized,...

by hunters for the illegal bushmeat market, compared with museum specimens and existing databases, verified a unique DNA signature for Colobus congoensis, as detailed in the study. Genetic Insights Trace Deep Divergence Phylogenetic work identified the...

a universal bacterial gene marker to catalogue species present. Second, they applied shotgun metagenomics to sequence DNA fragments from the entire community, revealing functional genes across diverse taxa. Third, they employed GC‑MS/MS analysis to...

statistical frameworks unavailable to earlier studies. They highlighted that earlier work suffered from limited Zorapteran DNA and uneven sampling across relevant insect groups. By scaling up the dataset and employing models designed to filter...

that ultimately generate sperm. During this interval the cells underwent a genome‑wide epigenetic reset—a sweeping removal of DNA‑associated chemical tags that normally regulate gene activity [6]. The reset appeared “dramatic,” aligning the cells’...

work Classic of Mountains and Seas, a reference to the snail’s eyeless condition and unusual appearance. Mitochondrial DNA analysis of the cytochrome c oxidase subunit I (COI) gene placed Erhaia dijiang as a sister lineage to Erhaia daliensis, the type...

cut and clip these changes off of the proteins,” Cravens told The Scientist. Using artificial intelligence, the team screened DNA from more than 50,000 microbial species and modeled the structures of the encoded enzymes. They filtered candidates for...

After predator control saved a near‑collapsed population, DNA shows extreme inbreeding but surprisingly fewer harmful mutations. By 2008, fewer than 80 red-headed wood pigeons survived on Japan’s remote Ogasawara archipelago. The birds, found only on...

Influences a Black Fungus Ionizing radiation can strip electrons from atoms, damaging cellular components and fragmenting DNA. In experiments coordinated by Ekaterina Dadachova and Arturo Casadevall of the Albert Einstein College of Medicine, the fungus...

and Homo sapiens interbred during their migration out of Africa. These ancient unions left behind traces of Neanderthal DNA in modern human populations, a testament to the complex, fluid nature of our evolutionary lineage—one that is far more nuanced...

effort involving the University of Oxford and the National Museum of Namibia. By applying stable-isotope analysis and ancient DNA sequencing, researchers are successfully mapping the origins of this ivory to specific West African forest habitats. The...

a remarkable ability to survive the simulated lunar environment, likely due to its robust cell walls and effective DNA repair mechanisms. Researchers estimate that in certain shadowed niches, this fungus could persist for over a week. While the Moon...

Genetic Identity and Evolutionary Origins To confirm the species identity, Kakui and his co-author, Aoi Tsuyuki, utilized DNA extraction and microscopic sectioning. Genetic sequencing placed the worms within the order Tricladida, specifically the group...

in Global Ecology and Conservation, provided no evidence of cross-breeding. Sophisticated ancestry modeling and mitochondrial DNA analysis confirmed that the short-tailed individual was fully aligned with the wild leopard cat genetic cluster, with...

rats were discovered encased in spilled tar, their remains so well-preserved that they offer a rare opportunity for future DNA analysis. Tracing the Timber of a Medieval Trade Powerhouse A comprehensive dendrochronological study, published in May 2026...

a prototype that does not yet account for the complex, temporary “handshakes” between proteins or their interactions with DNA. Furthermore, while the model has shown potential in lab-grown cells, its ability to translate those findings into human...

while another focuses exclusively on the hindbrain. This distinction is dictated by chromatin, the structural complex of DNA and proteins that governs gene expression. Even when these cells appear visually identical under a microscope, their chromatin...
