Epigenetic Signatures Explain How Andean Highlanders Thrive in Low Oxygen

DNA sequencing technology makes it possible to explore the genome to learn how humans adapted to live in a wide range of environments.

Study Uncovers Principles Guiding Replication Initiation Across the Human Genome

When cells proliferate, genomic DNA is precisely duplicated once per cell cycle. Abnormalities in this DNA replication process can cause alterations in genomic DNA, promoting cellular aging, cancer, and genetic disorders.

Study Reveals How Cells Compensate for Missing Chromosomes

A hallmark of cancerous cells is an abnormal number of chromosomes or chromosome arms, known as aneuploidy.

New Evidence Shows Complex Life Began Far Earlier Than Previously Believed

Complex life began to develop earlier, and over a longer span of time, than previously believed, a groundbreaking new study has revealed.

Study Exposes Ancestry Biases in Current Gene Annotations

Human gene maps contain major blind spots because they were built largely from the DNA sequences of people with European ancestry, according to a study published today in Nature Communications.

Harnessing Triploid Loquat to Unlock Aneuploid Diversity for Advanced Breeding

Triploid plants are widely valued in horticulture for desirable traits such as seedlessness, yield improvement, and stress resilience.

New Label-Free Breakthrough for Studying Bacterial Shape Diversity

Scientists have long known that bacteria come in many shapes and sizes, but understanding what those differences mean has remained a major challenge, especially for species that can't be grown in the lab.

Unraveling How GFAP Mutations Disrupt Mitochondria in Alexander Disease

Some brain disorders are straightforward, such as the direct frontal lobe assault of a concussion or traumatic brain injury. Others, like Alexander disease, are akin to guerilla warfare.

Ambiguous Stop Codons Expand the Genetic Code in Archaea

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that's added to a chain of amino acids to make a protein.

Study Uncovers How Polyploid Plants Harness Transposons for Evolutionary Innovation

Polyploidization, the combination and duplication of genomes, is a major driver of plant evolution and diversification. Yet this process causes "genome shock," leading to rapid activation of transposable elements (TEs).

CRISPR Technologies Transform On-Site Detection of Animal Pathogens

The rapid spread of animal diseases and pathogen evolution have long posed significant threats to the healthy development of animal husbandry.

Real-Time Visualization Reveals the Transcriptional Gearbox

Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins.

New Regulatory Pathway Enhances Key Aroma Compound in Wine Grapes

β-Damascenone is a key norisoprenoid compound responsible for characteristic floral and fruity aromas in grapes and wines, particularly those from non-aromatic varieties such as Cabernet Sauvignon and Merlot.

Gene Transcription Start Sites Identified as Hidden Mutational Hotspots

Researchers have discovered new regions of the human genome particularly vulnerable to mutations. These altered stretches of DNA can be passed down to future generations and are important for how we study genetics and disease.

Scientists Map How Transcription Factors Interpret DNA Sequences

With a new study in the journal Cell, researchers at Stanford University and Stockholm University have contributed to increased knowledge about gene regulation in human cells.

DNA Rigidity Inside the Nucleosome Regulates INO80 Positioning

Researchers at The University of Texas MD Anderson Cancer Center have shown that DNA inflexibility, or rigidity, inside the nucleosome regulates the positioning of INO80. This highlights that the physical structure and shape of DNA, not just genetic information, are key components of DNA transcription.

Discovery Reveals Unexpected Role for OTULIN in Controlling Tau Expression

Scientists have uncovered a surprising mechanism by which a brain enzyme called OTULIN controls the expression of tau, the protein that forms toxic tangles in Alzheimer's disease.

Novel Mechanism for Epigenetic Patterning in Plants

Every cell within an organism shares an identical genetic blueprint. Their distinct identities stem from epigenetics—precise chemical markers that dictate gene expression.

Genetic Analysis Uncovers Six Distinct Lineages of Global Tea Germplasm

Using 150 single-nucleotide polymorphism (SNP) markers across 252 tea accessions from India and China, researchers identified six major genetic groups, including the small-leafed sinensis and five broadleaf assamica populations from India, Indochina, and Yunnan. The
