Scientists Discover How Embryos Develop Different Tail Types In a new study, scientists have uncovered the molecular mechanism responsible for the development of different tail types in embryos. New Method to Track Embryo Development in Real Time Researchers have developed a new method to track embryo development in real time that could revolutionize our understanding of how embryos form and grow. How Embryonic Cells Know When to Divide Researchers have discovered how embryonic cells know when to divide, providing an answer to a long-standing mystery about early embryo development.
Ancient viral DNA shapes early embryo development, study finds
Over half of our genomes consist of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the "dark side" of the genome, researchers at Helmholtz Munich and Ludwig-Maximilians-Universität (LMU) have now revealed their crucial role in early embryo development. The study is published in the journal Cell.
Many Roads Lead to... the embryo | ScienceDaily
Is there only one optimal configuration an organism can reach during evolution? Is there a single formula that describes the trajectory towards the optimum? And can we 'derive' it in a purely theoretical fashion? A team of researchers has answers. Their mathematical model forecasts the ideal body plan of a fruit fly's early embryo, suggesting that evolution might had many optimal options at its disposal.
How it is possible to see Awoman in mid twenties with Bilateral Choanal atresia ? | Research Communities by Springer Nature
Choanal atresia is a congenital anomaly characterized by an absence of the nasal choanae due to Failure to recanalize the nasal fossae during embryogenesis. Bilateral choanal atresia presenting in adulthood is an infrequent occurrence.
Birds have developed complex brains independently from mammals | ScienceDaily
New research has revealed that birds, reptiles, and mammals have developed complex brain circuits independently, despite sharing a common ancestor. These findings challenge the traditional view of brain evolution and demonstrate that, while comparable brain functions exist among these groups, embryonic formation mechanisms and cell types have followed divergent evolutionary trajectories.
Birds have developed complex brains independently from mammals, studies reveal
Two studies published in the latest issue of Science have revealed that birds, reptiles, and mammals have developed complex brain circuits independently, despite sharing a common ancestor. These findings challenge the traditional view of brain evolution and demonstrate that, while comparable brain functions exist among these groups, embryonic formation mechanisms and cell types have followed divergent evolutionary trajectories.
Spider development and vision: A genetic perspective
A new study provides detailed insights into the embryogenesis and eye development of the cave-dwelling spider Tegenaria pagana. The research, published in EvoDevo, examines key genetic mechanisms involved in eye formation and how they compare to other spider species.
Sperm breach blastocyst defenses in primates, providing new insights into reproductive competition
In a study of early embryonic development in primates, an international research team under the leadership of Berthold Huppertz and Thomas Kroneis from Med Uni Graz has shown for the first time that sperm can penetrate the outer layer of five- to seven-day-old embryos (blastocysts).
From dinosaurs to birds: the origins of feather formation | ScienceDaily
Feathers, essential for thermoregulation, flight, and communication in birds, originate from simple appendages known as proto-feathers, which were present in certain dinosaurs.By studying embryonic development of the chicken, researchers from the University of Geneva (UNIGE) have uncovered a key role of a molecular signalling pathway (the Shh pathway) in their formation. This research provides new insights into the morphogenetic mechanisms that led to feather diversification throughout evolution.
