This research offers both a scientific and ethical alternative to the use of embryos resulting from fertilized human eggs, and the appropriate ethical guidelines have been developed in parallel with the advances being made. A group of biologists and ethicists suggest additions to the current ethical framework that refine thinking about human embryology using embryo models to maximize benefits to society.

But certain sugars naturally found in breastmilk could also help prevent infections before a baby arrives. Researchers have found that these sugars can stop a common prenatal infection in human tissues and pregnant mice. This could someday help people avoid preterm births or complications without the need for additional antibiotics.

The research suggests that many babies exposed to steroids avoid preterm birth, but new risks for other future health complications are introduced.

It was previously understood that in rodents, prenatal stress affects microbiomes into adulthood, but how long after birth the effects lasted in humans was unknown. The changes to this community of microorganisms are likely among the ways that hardship affects a child's socioemotional development.

This is because human embryos are typically not cultured for longer than 14 days because of bioethical concerns, and gastrulation occurs between 17- and 21-days post-fertilization. In addition, current stem cell models that mimic gastrulation have not been able to include the necessary extraembryonic tissues that give rise to the yolk sac and the placenta. Researchers now report a new method to develop 'peri-gastruloids,' an embryo-like structure that includes one of the supporting tissues, the yolk sac, missing from previous models.

Aside from lifestyle, predisposition plays a role, but genes cannot fully explain the inherited propensity to accumulate excess weight. A new study shows that a kind of formatting of the DNA code in one gene that is associated with satiety is implicated in a slightly elevated risk of excess body weight -- at least in women. This 'epigenetic marking' is established early on during the embryonic stage.

The study established a new link between genomic instability and a protein from Mycoplasma fermentans, a kind of bacterium that commonly colonizes the urogenital tract. This bacterial protein also reduced fertility in mother mice and resulted in more birth defects in their newborn pups.

The model, or 'knowledge graph,' also has the potential to predict the involvement of pre-clinical compounds that may harm the developing fetus. The study is the first known of its kind to use knowledge graphs to integrate various data types to investigate the causes of congenital disabilities.

In the stage known as gastrulation, the transformation of embryonic cells into specialized cells begins. This initiates an explosion of cellular diversity in which the embryonic cells later become the precursors of future blood, tissue, muscle, and more types of cells, and the primitive body axes start to form. Studying this process in the human-specific context has posed significant challenges to biologists, but new research offers an unprecedented window into this point in time in human development.

Time-restricted fasting is an eating pattern where people limit their food consumption to certain hours of the day. It's a popular health and fitness trend and people are doing it to lose weight and improve their health. But the new study shows that time-restricted fasting affects reproduction differently in male and female zebrafish. Importantly, some of the negative effects on eggs and sperm quality can be seen after the fish returned to their normal levels of food consumption. The research team say that while the study was conducted in fish, their findings highlight the importance of considering not just the effect of fasting on weight and health, but also on fertility.

New evidence suggests that the answer may be 'no.' Researchers report that mothers are able to transfer microbes to their babies via alternative, compensatory routes.

Although gene editing technologies hold promise in preventing and treating debilitating inherited diseases, the new study reveals limitations that must be overcome before gene-editing to establish a pregnancy can be deemed safe or effective.
