Two flu vaccine doses boost benefit for children younger than 3 years

A review in Clinical Epigenetics synthesizes growing evidence that paternal lifestyle and environmental exposures such as diet, obesity, smoking, endocrine-disrupting chemicals, and stress alter sperm epigenetic marks (DNA methylation, histone retention, and small non-coding RNAs). These changes can influence sperm quality and fertilizing ability, early embryo development, assisted reproduction outcomes, and long-term health risks in offspring.

When we are engaged in a task, our brain's auditory system changes how it works. One of the main auditory centers of the brain, the auditory cortex, is filled with neural activity that is not sound-driven—rather, this activity times the task, each neuron ticking at a different moment during task performance.

Air pollution is one of the world's leading health risks, contributing to nearly one in eight deaths globally. A new study published in Science Advances by the Euro-Mediterranean Center on Climate Change (CMCC) shows that stringent climate policies designed to avoid temporarily exceeding 1.5°C warming could prevent hundreds of thousands of premature deaths while avoiding trillions of dollars in economic damages.

When immune cells strike, precision is everything. New research reveals how natural killer and T cells orchestrate the release of toxic granules—microscopic packages that destroy virus-infected or cancerous cells.

Late nights, early risings and broken sleep schedules are hallmarks of youth, but those sleepless nights may leave marks deeper than dark circles under the eyes.

Researchers from Rutgers Health and other institutions have discovered why a powerful leukemia drug eventually fails in most patients—and found a potential way to overcome that resistance.

As artificial intelligence (AI) use continues to grow in nearly every industry, it is important to establish guardrails to make sure the technology is used ethically and responsibly. This is especially true in the field of medicine, where errors can be a matter of life and death and patient information must be protected.

Florida wildlife officials have confirmed the state's second case of a deadly and highly contagious infection known as "zombie deer disease" in a wild deer.

The accuracy of child car seat installation and restraint usage following education with a remotely located technician is noninferior to that with an on-site technician, according to a study published online Oct. 13 in Pediatrics.

Michael Gotthardt at the Max Delbrück Center and collaborators are developing a drug to treat a common type of heart failure characterized by impaired cardiac filling. In a recent study, his group and a US team showed the therapy improves cardiac function in a mouse model of the disease.

Two types of industrially processed hard fats, widely used in everyday foods such as bakery products, margarines and spreads, are unlikely to affect heart health when consumed in levels achievable in most people's diets.

A new analysis reveals how deeply the U.S. drug supply chain depends on China, and experts warn that a trade war could leave American patients at risk.

Scientists at University College London have engineered a rare type of immune cell to kill slow-growing bowel cancer cells that are resistant to current therapies, a breakthrough that could lead to new treatments in the future.

For people with medical conditions, stigma is a real problem they must worry about on top of their health. Stereotypes about health conditions often cause discrimination even by health care providers, as many may assume those affected don't take care of their health, when in reality they likely have no control over their condition.

Researchers led by Masako Tamaki at the RIKEN Center for Brain Science in Japan report a link between deep sleep and cerebrospinal fluid, the clear liquid that surrounds and supports the brain and spinal cord. Published in Proceedings of the National Academy of Sciences, the study demonstrates how changes in cerebrospinal fluid signals during sleep—as measured by MRI—are time-locked to slow brain waves and other neural events.

Preexisting hyperlipidemia in pregnancy is associated with heightened risks of obstetric complications and early cardiovascular events in the first five years postpartum, according to a new study being presented at ACC's Cardio-Obstetrics Essentials: Team-Based Management of Cardiovascular Disease and Pregnancy conference.

About half of women over 40 have dense breasts. The denser the breast tissue, the more difficult it is to spot cancer on a standard mammogram. Having dense breast tissue can make it harder to detect cancer and sometimes leads to consideration of supplemental screenings along with your mammogram.

When cancer spreads, tiny amounts of cells can break away from tumors and circulate in the bloodstream. A liquid biopsy is a means to detect the presence of cancer by detecting these cancer cells floating in blood samples. However, current state-of-the-art methods have necessitated trained specialists to comb through and review images of thousands of cells out of potentially millions of cells on a slide over a period of many hours.
