A new research paper was published in Aging (Aging-US) Volume 17, Issue 3, on March 5, 2025, titled "Reproductive aging, preimplantation genetic testing for aneuploidy, and the diameter of blastocysts ...

"Preimplantation genetic testing for aneuploidy (PGT-A) has emerged as a powerful tool in assisted reproductive technology, offering the potential to enhance the chances of successful embryo ...

New research has revealed that fish embryos actively control their hatching timing through a neurohormone, Thyrotropin-Releasing Hormone (TRH), which triggers the release of enzymes that dissolve the ...

Amphibian embryos exhibit remarkable hatching plasticity, enabling them to adjust the timing of hatching in response to environmental cues, particularly those signalling predation risk. This adaptive ...

Extracellular vesicles (EVs) and their cargo microRNAs (miRNAs) are important regulators of embryo development to the blastocyst stage and beyond. Before implantation can take place, hatching of ...

Scientists report a documented case of a coral reef fish directly regulating when its offspring hatch. Male neon gobies hatch their embryos by removing eggs from the nest with their mouth, ...

A fossilized dinosaur embryo discovered inside a fossilized egg in southern China is reshaping scientific understanding of avian evolution. Preserved for more than 70 million years and left unexamined ...

A new study from the Smithsonian Tropical Research Institute (STRI) shows that red-eyed treefrog embryos hatch early when exposed to high ammonia levels — an environmental cue that it’s too hot and ...
