A new study from the University of South Australia confirms that eggs are not high in cholesterol and do not contribute to cardiovascular disease. In contrast, saturated fat intake was found to increase LDL levels, highlighting the importance of dietary balance for heart health.
Researchers from the Wellcome Sanger Institute mapped the multiple organ functions of the human yolk sac, revealing its role in producing key hormones and blood cells. The study provides novel insights into the earliest stages of immune cell development and has implications for understanding childhood diseases.
Scientists have developed an innovative method to create 'peri-gastruloids,' human embryo-like structures with extraembryonic tissues, including yolk sac and placenta. This breakthrough allows researchers to study early human development stages, mimicking the formation of vital organs.
Researchers at Monell Chemical Senses Center found that certain food proteins like egg yolk can suppress the bitter taste and pungency of extra virgin olive oil. This discovery may encourage increased consumption of healthy olive oil for cooking and medicinal purposes.
Elvira Mass has made a significant contribution to understanding the role of yolk sac-derived macrophages in maintaining healthy organs. Her research found that these cells can self-maintain for a lifetime, producing bioactive molecules and growth factors essential for tissue development.
Researchers found that rotational deceleration causes tremendous egg yolk deformation, shedding light on brain deformation during impacts. This finding suggests that rotational impact is more harmful to brain matter than direct translational impact.
Researchers develop novel template-directed approach to create hollow metal-organic framework (MOF) capsules for encapsulating soluble active species. The resulting yolk-shell MOF capsules exhibit superior activity, combining the merits of homogeneous and heterogeneous catalysts.
Researchers at IST Austria discovered that combined pulling and pushing forces within the embryo facilitate the segregation of cytoplasm from the yolk granules. Actin flows towards the animal pole drag along cytoplasm, while comet-like actin structures push yolk granules towards the vegetal pole.
A large study of nearly 30,000 adults found that consuming 300 mg of dietary cholesterol per day increases the risk of cardiovascular disease by 17% and death by 18%. The study also linked eating three to four eggs per week to a 6% higher risk of cardiovascular disease and an 8% higher risk of any cause of death.
Researchers Anthony Nash and Lauren von Blohn investigated the acoustic properties of exploding eggs in a microwave oven. They discovered that the yolk's temperature is consistently higher than the surrounding water bath, leading to superheated pockets that cause a chain reaction resulting in an explosion-like phenomenon.
A new species of bird, Eoconfuciusornis, has been found with exceptionally preserved soft tissues, including feathers, skin, and collagen. The discovery provides valuable insights into the evolution of flight in birds, revealing unique features such as wing patagia and plumage patterns.
A study on live-bearing sea anemones found that offspring transition from using egg yolks to pre-natal and post-natal parental feeding during development. The researchers also discovered a possible link between size variation within the clutch and parent-offspring conflicts or sibling rivalry.
Biologists from KU Leuven discovered that nematode eggs can hatch without egg yolk, defying the rule that no yolk means no offspring. The finding opens new avenues for deworming products without side effects on humans.
A UMass Amherst biologist is developing a new liver model using extra-embryonic tissue to study liver function and mechanisms. The model, which uses tissues from the yolk sac, offers a simpler alternative to traditional liver models, allowing for more efficient analysis of gene expression and protein production.
Researchers at MIT have developed a novel electrode made of nanoparticles with a solid shell, and a yolk that can change size without affecting the shell, improving cycle life and energy storage. The use of aluminum as the key material has proven to be high-rate champion among high-capacity anodes.
Regular egg yolk consumption accelerates atherosclerosis in a manner similar to smoking cigarettes, according to a new study published in the journal Atherosclerosis.

A new rapid-cooling process can extend egg shelf life by up to 12 weeks, maintaining protein quality and preventing bacterial invasion. The technology uses liquid carbon dioxide to cool eggs quickly, reducing the risk of salmonella illnesses.
Researchers at TUM discovered that macrophages can originate from two distinct cell lines: one from hematopoietic stem cells and the other from yolk sac cells. The study reveals that yolk sac-derived macrophages migrate to organs during embryonic development and remain there, while blood-circulating macrophages are replaced by stem cells.
Researchers found that egg yolks contain two amino acids with high antioxidant properties, making them comparable to apples in preventing cardiovascular disease and cancer. However, cooking methods significantly reduce these properties.
Researchers studied avian embryos to understand mechanisms of epiboly, a developmental process linked to wound healing and cancer. They discovered new molecules and protein expression patterns that may be unique to the avian embryo.
A new study reveals that female striped plateau lizards' colorful patches during reproduction season boost yolk antioxidants in their eggs, resulting in healthier offspring. The research suggests that females with more vibrant coloration may be more attractive to males and produce higher-quality offspring.
A review published in the Canadian Journal of Cardiology finds that consuming egg yolks can significantly increase cardiovascular risk for patients at risk of vascular disease. The researchers advise limiting dietary cholesterol to less than 200mg per day and recommend alternative protein sources like egg whites.
Research shows that in one lizard species, bigger eggs tend to produce females and smaller eggs tend to produce males. This discovery contradicts the long-held assumption that genetic factors control sex determination in reptiles.
A team of scientists studied how alligators grow and develop in different oxygen levels, discovering that low oxygen environments result in enlarged bellies and smaller organs, but also larger hearts. The study provides insights into the adaptations of dinosaurs to survive in a world with fluctuating oxygen levels.
Researchers found that fish raised with environmental features, such as small stones, had larger brains and a more developed cerebellum than those without. The study's findings could impact the design of hatcheries for breeding fish to restock wild populations.
The study found that enriched egg yolks increased red cell membrane DHA levels by 30-40% in both breast-fed and formula-fed infants. Additionally, plasma iron levels were improved in all groups, with no negative impact on cholesterol concentrations.
