It's a tiny marine invertebrate, no more than 3 millimeters in size. But closely related to humans, Botryllus schlosseri might hold the key to new treatments for cancer and a host of vascular diseases.
The evolution of the amniotic egg -- complete with membrane and shell -- was key to vertebrates leaving the oceans and colonizing the land and air but how bird eggs evolved into so many different shapes and sizes has long been a mystery. Now, an international team of scientists took a quantitative approach to that question and found that adaptations for flight may have been critical drivers of egg-shape variation in birds.
Researchers have found that genes for coronary heart disease (CAD) also influence reproduction, so in order to reproduce successfully, the genes for heart disease will also be inherited.
Paracetamol during pregnancy can inhibit masculinity Paracetamol during pregnancy can inhibit the development of 'male behavior' in mice. New research from the University of Copenhagen shows that it can reduce sex drive and aggressive behavior.
Scientists used human pluripotent stem cells to generate human embryonic colons in a laboratory that function much like natural human tissues when transplanted into mice, according to research published June 22 in Cell Stem Cell. The study is believed to be the first time human colon organoids have been successfully tissue engineered in this manner, according to researchers who led the project.
A developing fetus bathes in a mixture of cellular secretions and proteins unique to its mother's uterus. Before fertilization, the pH of uterine fluid helps create a conducive environment for sperm migration, and afterward, its volume supports the embryo as it implants onto the wall of the uterus. Recent evidence, presented in Trends in Molecular Medicine, suggests that uterine fluid may play another role in embryonic development: communicating the mother's outside conditions to the fetus,
Coronary artery disease may have persisted in human populations because the genes that cause this late-striking disease also contribute to greater numbers of children, reports Dr Sean Byars of The University of Melbourne and Associate Professor Michael Inouye of the Baker Heart and Diabetes Institute, Australia, in a study published June 22, 2017 in PLOS Genetics.
Researchers have identified structural changes in two genes that increase the risk of developing Tourette syndrome, a neurological disorder characterized by involuntary motor and vocal tics. The study, published in the journal Neuron, was supported by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health.
Researchers at The University of Texas Medical Branch at Galveston have shed light on how the developing brain ensures that connections between brain cells reach their intended destination but that they are also maintained during life-span.
Scientists studying a mystery link between the dangerous pregnancy complication pre-eclampsia and an increased risk of heart disease in later life for both mother and child have uncovered important new clues.
