Cornell researchers have uncovered the genetic triggers that cause male and female bovine embryos to develop differently, as early as seven to eight days after fertilization.

Hormonal birth control is a fact of life for millions of women. In the U.S. alone, more than 60 million women of reproductive age have used contraceptives according to the Centers for Disease Control and Prevention, most often to prevent pregnancy but also to manage conditions such as endometriosis, polycystic ovary syndrome and irregular cycles.

Gastric signet ring cell carcinoma (GSRCC) is a distinct subtype of gastric cancer (GC) with unique epidemiological and pathogenic characteristics.

Young children with attention deficit/hyperactivity disorder often receive medication just after being diagnosed, which contravenes treatment guidelines endorsed by the American Academy of Pediatrics, a Stanford Medicine-led study has found.

Increased testosterone levels are a consistent hormonal abnormality in women with polycystic ovary syndrome (PCOS). This study identified specific DNA variants in the gene DENND1A, which increase testosterone production in PCOS.

An international team led by researchers at Lund University in Sweden has identified the molecular tools needed to reprogram ordinary cells into specialized immune cells.

A new research paper was published in Volume 16 of Oncotarget on August 29, 2025, titled "In vivo manipulation of the protein homeostasis network in rhabdomyosarcoma."

A new scientific article, titled "Swine influenza surveillance in Italy uncovers regional and farm-based genetic clustering", has been published by Istituto Zooprofilattico Sperimentale delle Venezie as part of the Horizon Europe PAIR project.

When we think of child abuse, physical violence or emotional cruelty often comes to mind first. However, the most common form of maltreatment is actually much quieter: neglect.

Metals, particularly nickel and vanadium, and sulfate particles are the components of fine particulate air pollution (PM2.5) that most strongly contribute to the association between long-term exposure to air pollution and hospitalization among asthma sufferers, according to a new study led by Harvard T.H. Chan School of Public Health.

Taking low-dose colchicine daily may slow the progression of a common acquired gene mutation found in the blood of older adults that can lead to certain blood cancers and increased risk of cardiovascular disease, according to a subanalysis of the LoDoCo2 trial published in JACC, the flagship journal of the American College of Cardiology, and simultaneously presented at ESC Congress 2025.

Kidney diseases affect nearly 700 million people worldwide and are a growing cause of mortality and health care costs.

A new study has found that blood pressure synchronises to predictable phrase structures in music. Blood pressure was more affected by loudness than tempo and was more strongly influenced by phrase structures that were more predictable.

A new global systematic literature review and meta-analysis has shown that herpes zoster vaccination, used to prevent shingles, is associated with a statistically significant lower risk of heart attack and stroke.

In a new study published in the Journal of Hepatology, researchers from the San Raffaele Telethon Institute for Gene Therapy (SR-Tiget) show that only 15–20% of hepatocytes in newborn mice - dubbed clonogenic hepatocytes - are responsible for generating over 90% of the adult liver mass.

Pertussis, commonly known as whooping cough, is a vaccine-preventable disease which continues to circulate even in areas where vaccination coverage is high, and outbreaks may still occur. A study published in Eurosurveillance and conducted at Meyer Children's Hospital in Florence, Italy, has found a sharp increase in hospitalisations for pertussis among children and adolescents (patients aged 16 years or under) in 2024.

Anorexia is a serious mental health disorder that typically begins during adolescence. A study, conducted by the Research Unit of Population Health and Oulu Business School at the University of Oulu, examined how anorexia in adolescence affects labor market position in adulthood compared with peers.

Cardiologists have long known that up to half of all heart attacks and strokes occur among apparently healthy individuals who do not smoke and do not have high blood pressure, high cholesterol, or diabetes, the "standard modifiable risk factors" which doctors often call "SMuRFs."

Cellular differentiation of stem cells into specialized cells requires many steps, including division, to create more cells; fate determination, which is a commitment to a specific lineage or developmental path; and migration, to integrate the cell into its final location.

Chewing gum offers health benefits beyond oral care, enhancing performance and recovery, but research gaps for children and seniors need addressing.
