Cells balance protein production and removal through passive adaptation

Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids but cannot simply accumulate inside the cell forever.

Viral DNA elements help control early embryonic development

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' genomes during infection.

Early embryos and the uterus engage in active communication during implantation

A new study shows that the embryo and the uterine lining conduct an active "conversation" from the very earliest stages of implantation. They engage in a back and forth of tiny packages called extracellular vesicles and lipid droplets, which carry metabolites and signals.

New insights into alcohol-related DNA damage and cancer risk

Alcohol consumption leads to the formation of a toxic compound called acetaldehyde, which damages DNA.

Study reveals stepwise formation of cerebellar projections in the developing brain

A team of researchers at the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and Miguel Hernández University of Elche (UMH), has reconstructed for the first time how the cerebellum establishes its connections with the rest of the brain during the earliest stages of life.

White bread vs wholegrain: which one is actually better for your health?

This review dispels common myths about white and wholegrain bread by examining their composition processing and health effects. It concludes that while wholegrain breads offer added benefits white bread remains a safe affordable and nutritionally meaningful staple when fortified.

Tenascin C as a key to restoring muscle regeneration in aging

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.

Researchers discover new mutation hotspot in the human genome

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.

Study uncovers role of mechanical forces in human gastrulation

Only two weeks after fertilization, the first sign of the formation of the 3 axes of the human body (head/tail, ventral/dorsal, and right/left) begins to appear.

Maternal age drives embryo arrest independently of chromosomal errors

A new research paper was published in Volume 17, Issue 10 of Aging-US on October 10, 2025, titled "Developmental arrest rate of an embryo cohort correlates with advancing reproductive age, but not with the aneuploidy rate of the resulting blastocysts in good prognosis patients: a study of 25,974 embryos."

Scientists investigate the role of the extracellular matrix in tissue growth

Growing from a single cell into a complex organism with specialized tissues and organs requires a complex and coordinated process.

Study finds increased rates of DNA mutations in mice pups conceived with IVF

Mice pups conceived with in vitro fertilization (IVF) in the lab have slightly increased rates of DNA errors, or mutations, compared to pups conceived naturally, a new study on artificial reproductive technologies suggests.

Terasaki Institute and Caltech join forces on groundbreaking embryo formation study

The Terasaki Institute for Biomedical Innovation (TIBI) is pleased to announce its collaboration with the California Institute of Technology (Caltech) on a newly awarded $2.8 million Discovery Stage Research (DISC0) grant from the California Institute for Regenerative Medicine (CIRM).

Hiiragi group and Prevedel group collaborate with Prospective Instruments to pioneer intravital multiphoton microscopy for early embryo research

Prof. Takashi Hiiragi (Hubrecht Institute), Dr. Robert Prevedel (European Molecular Biology Laboratory), and Dr. Lukas Krainer (Prospective Instruments) have launched an interdisciplinary collaboration to develop a novel intravital microscopy platform for studying mammalian embryo implantation.

Micro-RNA in sperm proves vital for human embryogenesis

The sperm is not a passive supplier of genetic material to the egg. A study from Linköping University, Sweden, shows that certain molecules that come with the sperm, so-called micro-RNA, contribute to the development of the embryo several days after conception. The findings, published in the journal Nature Communications, may in the long term contribute to better diagnosis and treatment of involuntary childlessness.

Scientists identify essential process that protects DNA integrity in reproductive cells

A team of scientists at the University of Seville has identified an essential process that protects DNA integrity in reproductive cells, providing new clues about how organisms avoid genetic defects during egg formation.

Columbia researchers report first successful pregnancy using AI-guided sperm recovery method

Researchers at the Columbia University Fertility Center reported the first successful pregnancy using an AI-guided method they developed to recover sperm in men with azoospermia, in which ejaculate contains little or no sperm.

Discovering the role of lingual and buccal cells in tooth development

A novel study on the natural coordination of tooth development in time and space, led by Dr. Han-Sung Jung at the Yonsei University College of Dentistry, Korea, has discovered that "lingual" cells on the side of the tongue form the tooth, whereas those toward the cheek, called "buccal cells," form the bones and gums, guided by signaling molecules like WNT and BMP.

Study: Common test to assess viability of IVF embryos may be flawed

A test deployed in many fertility clinics to assess the viability of embryos for use in IVF is likely to overestimate the number of embryos with abnormalities, suggests a study published today.

Researchers achieve proof of concept for generating eggs from somatic cells

Researchers at Oregon Health & Science University have accomplished a unique proof of concept to treat infertility by turning skin cells into eggs capable of producing early human embryos.
