Innovative SenMayo Gene Set Consistently Identifies Diverse Senescent Cells

A series of seven Mayo Clinic studies is helping reshape scientists' understanding of senescent, or "zombie," cells - aging cells that no longer divide but remain metabolically active and release inflammatory molecules that contribute to age-related diseases.

Dysfunctional Mitochondria Control Epigenetic Switches to Turn On Inflammatory Genes

Researchers have uncovered a previously unknown mechanism that helps aging cells drive the chronic inflammation linked to many age-related diseases.

University of Oklahoma Study Uncovers Internal Recycling System in Photoreceptors

For decades, scientists believed that photoreceptors in the retina relied primarily on neighboring support cells, known as the retinal pigment epithelium (RPE), to remove waste. While the RPE is still responsible for clearing away the worn-out tips of photoreceptors each day, new findings from the University of Oklahoma reveal that photoreceptors also perform much of their own internal housekeeping.

Harvard Biologists Discover Unique Ribosome Adaptation in Shallow Water Octopuses

The octopus is a biological oddity. It can use tools, open jars, and its complex nervous system supports as many neurons as a small primate.

Structural Proteins Control Stem Cell Division to Stop Tissue Tumors

In many animal tissues, stem cells continually divide to create new cells that replace old or damaged ones. However, this capacity requires strict regulation, as uncontrolled stem cell proliferation can disrupt tissue homeostasis and contribute to tumorigenesis.

Scientists Discover Molecular Mechanism Behind Red and Green Color Vision

Human color vision depends on three types of cone cells in the retina. Although all three contain the same light-absorbing molecule, 11-cis-retinal, differences in the surrounding protein determine sensitivity to red, green, or blue light.

Dengue Virus Replicates Inside Memory B Cells to Evade Immunity

Researchers at the University of Vermont Robert Larner, M.D. College of Medicine and Upstate Medical University in Syracuse, NY, have discovered that dengue virus can infect and replicate inside memory B cells, immune cells traditionally understood to help protect the body from infection.

Novel Dendritic Cell Vaccine Redirects Viral Memory to Fight Tumors

In a discovery that could redefine the future of cancer immunotherapy, scientists from Celloram Inc., University Hospitals and Case Western Reserve University have developed a novel cancer vaccine platform that transforms the impact of the largest immunological event in modern history

3D Mapping of Tonsil Genetic Structures Unlocks Antibody Optimization

About 2 meters worth of genetic material must fit into the nucleus of each and every one of most of our trillions of cells, coiling and winding to form what looks like a tangled mess.

Deep-Learning Holography Detects Elusive Circulating Tumor Cells in Prostate Cancer

Researchers combined microfluidic enrichment, AI-assisted holography, and fluorescence profiling to identify circulating tumor cell candidates in 13 men with metastatic castration-resistant prostate cancer and 8 healthy donors. The platform found higher median candidate counts in patients, while nearly two-thirds of PSMA-positive candidates lacked EpCAM, suggesting EpCAM-dependent assays could miss some cells.

New Molecule Restores Muscle Repair Signal Linked to Age-Related Muscle Loss

One of the first tissues to deteriorate with aging is skeletal muscle. Weakness, scarring, internal muscle fat accumulation, and the loss of fast-twitch muscle fibers—which are crucial for rapid and forceful movements—can result from this deterioration.
