Researchers at the University of Pennsylvania have discovered a critical regulatory role of protein CTCF in controlling gene imprinting in eggs. The study found that lower levels of CTCF resulted in higher DNA methylation and reduced fertility in female mice.
A study by the Lister Fertility Clinic in London found that women who participated in an egg-sharing program did not have a lower chance of getting pregnant or having a live birth compared to those who didn't participate. The researchers also found no evidence of increased risk of ovarian hyperstimulation syndrome among donors.
Marine biologists have discovered a unique undersea nursery off Northern California, where groups of fish and octopus brood their eggs. The discovery represents a new type of biological hot spot, with potential implications for conservation efforts.
Researchers isolated a honeybee gene called csd, revealing that female bees have two different versions of the gene that form an active protein triggering female development. This discovery explains how male and female bees develop from fertilized and unfertilized eggs, respectively.
A team of Australian researchers has received a five-year grant from the National Institute of Child Health and Development to investigate how environmental stress affects embryonic development. The study aims to understand the long-term health implications for children conceived during poor maternal health or adverse lifestyle choices.
The research team successfully cloned a mule, marking the first time a hybrid animal has been cloned. The cloning process uses fetal cell culture established in 1998 at the University of Idaho and demonstrates potential for advancing understanding of human cancer.
Researchers used fruit flies to study how age affects meiosis, a specialized cell division that gives rise to eggs and sperm. The study found that as fruit fly eggs 'age', errors in cell division increase, mirroring the phenomenon in humans, where birth defects like Down syndrome rise with maternal age.
Researchers have discovered that Solanum sisymbriifolium can eliminate potato cyst nematodes from the soil, which are difficult to control. By cultivating this plant between potato harvests, farmers may be able to reduce the need for pesticides and improve crop yields.
Female coots can accurately count their own eggs in a mixture, rejecting parasitic eggs and altering clutch size. This remarkable feat provides insight into the complex defense mechanisms used by coots to thwart brood parasitism.
A new study published in Breast Cancer Research found that higher levels of egg consumption during adolescence are associated with a decreased risk of breast cancer. Eating dietary fiber and vegetable fat was also attributed to a reduced risk, while butter appeared to increase the risk.
Researchers found that the interaction between Lithophragma parviflorum and Greya politella is a rare example of coevolution in action, with outcomes ranging from mutualism to antagonism. The study highlights the importance of considering large geographic scales to understand how coevolution shapes biodiversity.
Researchers have identified a human gene that appears to be the counterpart to the mouse Mater gene, essential for fertilized egg development. The discovery may lead to new approaches in studying and treating female infertility, as well as understanding the role of the immune system in premature ovarian failure.
Researchers discovered that parasitic worms develop normally into adults when in contact with specific immune cells in their host's liver, producing fewer eggs if disconnected. This adaptation allows the worms to thrive by exploiting their host's immune response.
Researchers found that mitochondrial organization in eggs is crucial for developing embryos. The study showed that the symmetry or asymmetry of mitochondria-carrying microtubules may determine an embryo's viability and success.
Researchers at Cornell University have found that releasing an early army of beneficial Trichogramma ostriniae wasps can halve European corn borer damage. The study suggests that growers only need to release around 30,000 wasps per acre and that subsequent releases may not be necessary.
A recent study by Dutch fertility experts suggests that women undergoing IVF treatment who have a low number of eggs retrieved are more likely to enter an early menopausal state. The research indicates a correlation between the age of menopause and the number of eggs produced, supporting one of the concepts of reproductive ageing. Howe...
Researchers develop novel method of membrane fusion to transfer infertile woman's nucleus into donor egg, enabling nearly full genetic contribution. The technique could help women with embryo development failures due to cytoplasmic defects in their own eggs.
Research suggests that children allergic to eggs are not at a higher risk of anaphylaxis from the measles, mumps and rubella (MMR) vaccine. A growing body of evidence shows that only minor reactions may occur in some cases.
Two companies, GeneWorks and AviGenics, are developing genetically engineered chickens to produce human growth factor and interferon for treating diseases. The birds can produce up to 100 milligrams or more of a drug in each egg, making the yields lucrative.
A team of scientists, led by Frankie Jackson of Montana State University, has uncovered a vast dinosaur nesting site in Patagonia, containing over 200 eggs and fossilized skin. The discovery provides valuable insights into the behavior, biology, and nesting strategies of long-necked sauropod dinosaurs.
Biologists have successfully developed a new method for preserving human eggs using a choline-based solution, which allows for higher survival rates compared to traditional methods. The breakthrough could pave the way for easier egg banking at fertility clinics and improve chances of motherhood for women with damaged ovaries.
A team of scientists, including MSU's Frankie Jackson, discovered a rare dinosaur embryo in Patagonia, Argentina, with implications for understanding sauropod reproduction. The find confirms the identity of the embryo as belonging to a type of plant-eating dinosaur.
A team of researchers announces the discovery of thousands of eggs and dozens of unhatched dinosaur embryos containing fossilized skin, representing a number of scientific firsts. The embryos belong to giant plant-eating dinosaurs called sauropods and are found in the southern hemisphere.
Researchers have made a groundbreaking discovery of dinosaur embryos with fossilized skin, providing the first glimpse into the soft tissue covering baby dinosaurs. The ancient eggs were found to contain patches of delicate skin and tiny teeth, shedding light on the reproductive habits of giant plant-eating sauropods.
Researchers successfully incorporated and reprogrammed genes from adult cells of various animal species into bovine eggs. The study's findings suggest a conserved molecular mechanism in mammals for embryonic reprogramming, enabling the use of cow eggs as a 'universal recipient' for genetic material from other species.
In a new study, biologist David Anderson found that masked boobies kill their own young to maximize reproductive success. By laying two eggs, the birds decrease their risk of total reproductive failure to about 16 percent.
Researchers at the USDA's Agricultural Research Service have developed new corn germplasm lines that resist two key nematode pests, Meloidogyne incognita and M. arenaria. These resistant plants can help farmers reduce yield losses of up to 30% in southern US states, with little or no treatment required.
