The study found that mild sleep apnea changed sugar levels during pregnancy and was connected to infant growth patterns related to increased risk of obesity.
The bird's trek between its breeding grounds in the central and western boreal forest of North America and its winter home in the Amazon Basin is one of the longest songbird migrations recorded. Describing a route arcing across North America and including a transoceanic flight to South America, the study confirms an epic migration journey that scientists had long suspected but not yet proved. Tracking their route is key to solving the birds' decline.
Women who develop diabetes in pregnancy but are not diagnosed are much more likely to experience stillbirth than women without the condition, according to new research.
Researchers, from the universities of York and Oxford, have discovered that a reinforcing outer-layer which coats the tails of human sperm is what gives them the strength to make the powerful rhythmic strokes needed to break through the cervical mucus barrier.
Results of a first-of-its-kind prospective study with a family planning app find it to be as effective as other modern methods for avoiding an unplanned pregnancy, according to Georgetown researchers.
Ram semen stored at the University of Sydney for 50 years has been used to successfully impregnate 34 ewes, with fertility rates as high as recently stored semen.
Scientists have found that sperm DNA from the testicles of many infertile men is as good as that of ejaculated sperm of fertile men. This may explain a major cause of male infertility and opens the possibility of using sperm taken directly from the testicles of these men; to overcome their infertility.
Researchers at the University of North Carolina School of Medicine used MRI brain scans and machine learning techniques at birth to predict cognitive development at age 2 years with 95 percent accuracy.
Puberty is much more than just a time of biological overdrive, propelled by sexual maturation. Progress in developmental science has greatly broadened the perspective of this critical maturational milestone.
The role played by symbiotic microorganisms isolated from the skin of anurans has been discovered by researchers in Brazil. The study is published in Proceedings of the National Academy of Sciences.
