New research is underway to decipher a fascinating biological puzzle—how some animals can naturally discard more than half of their genetic information during embryonic development. This radical ...

Chromosphaera perkinsii is a single-celled species discovered in 2017 in marine sediments around Hawaii. The first signs of its presence on Earth have been dated at over a billion years, well before ...

Scientists at the University of California, Santa Cruz (UCSC), used CRISPR to engineer cellular models of embryos that mimic what happens in the first few days after reproductive cells meet. These ...

Embryo development starts when a single egg cell is fertilized and starts dividing continuously. Initially a chaotic cluster, it gradually evolves into a highly organized structure. Scientists have ...

Intrauterine growth restriction contributes to high rates of “runt” piglets, which have a lower survival rate after birth.

CRCHUM researcher Sophie Petropoulos and her team reveal for the first time that the guinea pig pre-implantation embryo is very similar to the human embryo, spurring a better understanding of ...

Thermal manipulation during incubation represents an innovative approach to enhancing the physiological robustness of avian species in the face of escalating environmental temperatures. By ...

Konstanz researchers identify an enzyme that plays a role in the migration of cells in our body—not only during normal tissue formation and wound healing, but also when tumor cells metastasize. This ...

Every year, more than 100 million animals are used globally in biomedical research, yet over 90% of drugs that appear effective in animal trials fail during human clinical testing. 1 This staggering ...

Research cited from Duke University and Boston University, along with animal studies, clinical observations in IVF ...
