The spacing, timing, and shape matched patterns usually found in animals with left and right sides. The process raised a question. Why would a sea anemone use what looked like a tool common in far ...

A frog belonging to an endemic Western Ghats species has been discovered by researchers with a severe limb abnormality, indicating possible environmental stress in the region’s fragile ecosystem. The ...

Neurons placed inside engineered living bodies built from frog cells self-organize, become active, and reshape movement ...

BEIJING -- After years of dedicated research, a team of Chinese scientists has unveiled critical mechanisms governing early human embryonic development, offering novel theories and potential ...

In mammals, the fusion of sperm and oocyte gives rise to a totipotent zygote, which undergoes a series of cleavage divisions and differentiation events. During this process, the embryo transitions ...

Multicellularity is one of the most profound phenomena in biology, and relies on the ability of a single cell to reorganize itself into a complex organism. It underpins the diversity in the animal ...

In July 1932, young pathology resident Elizabeth M. Ramsey was performing a routine autopsy with a colleague at New Haven Hospital when she made an extraordinary discovery: an apparently normal human ...

Studying the shape of tissues and organs is critical to understanding how they are formed. Embryonic development happens in three dimensions, but many studies are limited by the use of two-dimensional ...

Microtubule asters in cytoplasmic extract of the African clawed frog Xenopus laevis. The spatio-temporal growth of the aster is coordinated by cell cycle waves that drive the polymerization (brighter ...

New research from the University of Newcastle has revealed that PFAS levels matching those found in the Williamtown contamination zone could significantly alter male reproductive health in ...

Transposable elements are stretches of DNA that can move around the genome. Many of these DNA sequences originate from long ago, when viruses inserted their genetic material into our ancestors' ...

A stem-cell-based monkey embryo model that self-organizes into a comprehensive body plan could lead the way to more-sophisticated models of early human development. Xiangyu Kong is in the Department ...
