Exclusive or longer duration of breastfeeding (at least six months) is associated with reduced odds of developmental delays, according to a study published online March 24 in JAMA Network Open.

Mothers experience major metabolic adaptations during pregnancy and lactation to support the development and growth of new life. Although many metabolic changes have been studied, body temperature regulation and environmental temperature preference during and after pregnancy remain poorly understood.

A study led by Prof. Liu Feng from the Institute of Zoology of the Chinese Academy of Sciences has identified a crucial role for the tryptophan-aspartic acid (WD) repeat protein 5 (Wdr5) in maintaining the survival and genomic integrity of hematopoietic stem and progenitor cells (HSPCs) during embryonic development. The findings were published in the Proceedings of the National Academy of Sciences.

When skin is cut or damaged, tiny cell fragments circulating in the blood, called platelets, arrive at the injury and spread out to stop the blood from leaking out. Once enough layers of platelets accumulate, like stacks of sandbags against a flood, a blood clot is formed, trapping red blood cells. When the break occurs in a blood vessel, the clot contracts to facilitate smooth blood flow through the vessels.

Ever since 1993, when a deadly disease outbreak in the Four Corners first revealed the presence of hantavirus in North America, New Mexicans have been warned to be on the lookout for deer mice, which harbor the microbe and can spread it through their droppings.

Zika virus and dengue virus are very close relatives. Both are mosquito-borne flaviviruses, and both specialize in infecting a host’s dendritic cells.

By analyzing huge amounts of biological data, the use of machine learning accelerates the identification of critical control hubs that are sensitive to changes in the network structure of the total controllability network, thereby having potential as diagnostic biomarkers and therapeutic targets for disease and cancer treatment.

A new study explores how epigenetic markers—chemical modifications that influence gene activity—can help predict the risk of developing cardiometabolic diseases and guide personalized prevention strategies. The findings are particularly significant as the prevalence of major cardiometabolic risk factors such as hypertension, diabetes, and obesity continues to rise despite advancements in health care and treatment. This trend highlights the need for better early detection and intervention.

Motion sickness is a very common condition that affects about one in three people, but the brain circuits involved are largely unknown.

People with a complex heart, kidney and metabolic-related condition who got better quality sleep were less likely to have an advanced stage of the illness than those getting poor sleep, according to a new study.
