Researchers have developed a new stem cell model of the mature human amniotic sac, which replicates development of the tissues supporting the embryo from two to four weeks after fertilization. This is ...

This valuable study reports the conservation of sperm-egg envelope binding by demonstrating successful recognition of the micropyle in fish eggs by the mouse sperm. However, the evidence supporting ...

Mammal's Lifespans Linked to Brain Size and Immune System Function, Says New Study May 8, 2025 — Why do cats generally live longer than dogs? New research suggests that longer lifespans of ...

The musculoskeletal system provides structural support, enabling movement such as walking and lifting, protecting internal ...

The evidence supporting most of the claims is convincing and this work will be of interest to the microbial rhodopsin community and neuro- and cardioscientists utilizing optogenetics in their research ...

The tool, the Duke Mouse Brain Atlas, combines microscopic resolution, three-dimensional images from three different techniques to create a detailed map of the entire mouse brain, from large ...

The embryo was made using a method called intracytoplasmic sperm injection (ICSI), a type of IVF that has been around since the 1990s. In regular IVF, an egg is put in a dish with many sperm cells, ...

as confirmed through comparisons with mouse brain data. “We humans quickly spot what matters in a crowded scene,” said Dr. C. Justin LEE, Director of the Center for Cognition and Sociality ...

Moreover, the researchers found that when the Lp-masks used in their method resembled a Gaussian distribution, the AI's internal processing patterns closely matched biological neural activity, as ...
