OIST Study Illuminates Cancer's Avoidance of Cellular Stress Responses

When cell division (mitosis) takes too long, it can be a sign that something is wrong with the cells, for example DNA damage or chromosomal instability.

Scientists Discover First Human DNA-Cutting Enzyme That Responds to Tension

An international research team at the University of Hong Kong has discovered a human protein known as ANKLE1, which is recognized as the first DNA-cutting enzyme (nuclease) in mammals that can detect and respond to physical tension in DNA.

Breaking the Interspecies Immune Barrier to Advance Human Organ Generation

Failure of human pluripotent stem cells (PSCs) to survive when grown with the PSCs of distantly related species occurs because of an innate immune reaction in the nonhuman cells, a study led by UT Southwestern Medical Center researchers suggests.

Restoring Tenascin-C Protein Could Help Prevent Age-Related Muscle Loss

As we age, the muscles we rely on for daily activities tend to become less reliable. With enough decline, even normal movements such as getting out of bed become risky.

Senescent Fibroblasts in the Tumor Niche Rewire Lung Cancer Metabolism and Plasticity

Senescent fibroblasts are aging cells that no longer divide and protect against tumor development. Yet two decades have gone by since cell biologist Judith Campisi, PhD, paradoxically demonstrated that these same cells can promote cancer growth in a laboratory setting.

PLAMseq Revolutionizes Simultaneous Analysis of Genome Proteins and Their Locations

A team from the Andalusian Centre for Molecular Biology and Regenerative Medicine (CABIMER) has developed an innovative technique called PLAMseq (proximity-labelled affinity-purified mass spectrometry plus sequencing) that, for the first time, allows simultaneous analysis of chromatin-associated proteins and their location in the genome in a single experiment.

New Microscopy Reveals How Cells Actively Capture the Flu Virus

Researchers at ETH Zurich have achieved an unprecedented live, high-resolution visualization of influenza virus infection within living cells.

Nearly 1/3 of Pesticides and Industrial Chemicals Harm Gut Bacteria

A study reveals that common pesticides and industrial chemicals inhibit gut bacteria, highlighting risks to health and the need for revised safety assessments.

Cells Use Condensates to Save RNA Messages During Stress

All cells need to sense and respond to their environment, to know when to activate genes, build proteins, and carry out their basic functions.

New Tool Predicts Which Intrinsically Disordered Regions Drive Condensate Formation

Fusion oncoproteins arise when a gene fuses with another gene and acquires new abilities. Such abilities can include the formation of biomolecular condensates, "droplets" of concentrated proteins, DNA or RNA.

Benchmarking DNA Language Models for Precision Genomics

Researchers at The University of Texas MD Anderson Cancer Center have performed a comprehensive evaluation of five artificial intelligence (AI) models trained on genomic sequences, known as DNA foundation language models.

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.

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.

Engineered Gut Bacteria With MiRNA Nanoparticles To Reverse IBD

Biomimetic nanoparticles delivering microRNA to gut bacteria enhance protective metabolites, repair intestinal barriers, and alleviate colitis symptoms.

Light-Activated AR3 Triggers Alkalinity-Driven Apoptosis in Cancer Cells

One of the hallmarks of cancer cells is their ability to evade apoptosis, or programmed cell death, through changes in protein expression.

Decoding the Interaction Between SV2A Protein and Anti-Epileptic Drugs

A multi-institute team led by St. Jude Children's Research Hospital and UT Southwestern Medical Center investigators established for the first time how certain drugs used to treat epilepsy affect their target.

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.

2 Dec 2025

Study Reveals ATM-Driven Mechanism Behind Telomere-Induced Senescence

After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres-the protective caps at the chromosome ends-those caps eventually become too short to prevent chromosome ends from being recognized as DNA breaks.

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.
