Analyzing genetic data from nearly 140,000 IVF embryos, researchers linked maternal DNA variants to increased risk of ...

New findings offer insight into why some embryos fail to develop past zygotic genome activation (ZGA), pointing to an unexpected root of human infertility. A critical point in early development is ...

By Dr. Priyom Bose, Ph.D. A newly revealed “aging cliff” in sperm RNA marks a conserved molecular transition from youth to later life, offering fresh insight into how a father’s age may influence the ...

The asteroid that struck the Earth 66 million years ago devastated life across the planet, wiping out the dinosaurs and other organisms in a hail of fire and catastrophic climate change. But new ...

The neonatal period, which is defined as the first 28 days after birth, is known to be a crucial stage in the development of the human brain. During this stage, the brain is known to grow ...

Our prehistoric human ancestors relied on deliberately modified and sharpened stone tools as early as 3.3 million years ago.

Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines nearly every aspect of their functioning. This ...
