Michigan State University scientists have pinpointed the molecular "switch" that supercharges sperm for their final sprint to an egg - a breakthrough that could reshape infertility treatments and pave the way for safe, nonhormonal male contraceptives.

Women living close to federally designated Superfund sites are more likely to develop aggressive breast cancers - including the hard-to-treat triple-negative subtype - according to new studies from Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine.

In a secondary analysis of a study of 200 classrooms, Mass General Brigham researchers found respiratory viral exposures were still high in those with HEPA purifiers, suggesting additional interventions are needed.

A new research paper was published in Volume 12 of Oncoscience on September 30, 2025, titled "Lifestyle and hormonal factors affecting semen quality and sperm DNA integrity: A cross-sectional study."

Liver fibrosis, a progressive scarring of the liver tissue, represents a major global health burden with limited treatment options.

UVA Health lung researchers are developing a promising approach to detecting patients at risk of interstitial lung disease (ILD), an increasingly common condition that is a leading reason for lung transplants.

New research has discovered that briefly altering how we perceive our own body can help unlock autobiographical memories – potentially even those from the early stages of childhood.

Respiratory viral diseases pose severe threats to animal health and global food security, especially in intensive pig farming systems.

Chikungunya is a vector-borne disease that affects both adults and children. While global efforts are ongoing to tackle chikungunya in adults, progress in addressing pediatric chikungunya remains inadequate.

Sepsis is a complex clinical syndrome characterized by dysregulated immune responses, systemic inflammation, and multi-organ dysfunction.

Conventional studies on stem cell fates are primarily focused on transcription factors, with the limited consideration for 3D genome architecture.

Abdominal aortic aneurysm (AAA) is a life-threatening vascular disorder that primarily affects elderly males.

Ischemic heart disease is the leading cause of death globally, causing approximately 9 million deaths annually.

Recently, a research team led by Professor Jian-Xun Wang and Professor Tao Yu from Qingdao University made a significant breakthrough in understanding the role of lactylation modification in aortic dissection (AD).

Hypertrophic cardiomyopathy (HCM), a common genetic heart disorder, is often caused by mutations in sarcomere-related genes.

Treatments for cancer are continuously improving, but they can still cause debilitating, even fatal, side effects.

A 6-year cohort study conducted by researchers from Japan, comprising nearly 39,000 older adults found that people living in rental flats and owner-occupied detached houses face higher risks of cardiovascular death compared with those in owner-occupied flats.

Higher levels of screen time in early childhood are associated with lower scores in reading and mathematics on Ontario's standardized tests, with each additional hour of daily screen time associated with a 10 per cent drop in the likelihood of achieving higher academic levels.

Scientists have identified an unusual type of brain cell that may play a vital role in progressive multiple sclerosis (MS), likely contributing to the persistent inflammation characteristic of the disease.

Caffeine's impact on pregnancy is nuanced; moderate consumption may not lead to major complications, but risks to fetal growth persist without a safe threshold.
