New research from the Layden Lab at Lehigh has demonstrated that the gene mechanisms at work during neurogenesis in the brain actually predate the evolutionary development of the central nervous system. In other words, to ...

Although the Human Genome Project announced the completed sequencing of 20,000 human genes more than 20 years ago, scientists are still working to grasp how fully formed beings emerge from basic genetic instructions.

(Phys.org) —In many regards, a brief time-lapse video can teach more about embryonic development than any amount of reading. It is hard not to be impressed how a repeatable form reliably emerges despite considerable variation ...
A team of Duke researchers has identified a group of human DNA sequences driving changes in brain development, digestion and immunity that seem to have evolved rapidly after our family line split from that of the chimpanzees, ...

The search for the holy grail of regenerative medicine -- the ability to "grow back" a perfect body part when one is lost to injury or disease -- has been under way for years, yet the steps involved in this seemingly magic ...

A woman's supply of eggs is finite, so it is crucial that the quality of their genetic material is ensured. New work from Carnegie's Marla Tharp, Safia Malki, and Alex Bortvin elucidates a mechanism by which, even before ...

Tadpoles of frogs that can typically regrow amputated tails or limbs lost their ability to regenerate after researchers blocked the expression of a newly identified gene that is one of the drivers for this regrowth. Furthermore, ...

Life began on Earth more than 3.5 billion years ago, but the history of humans and other vertebrates accounts for only a fraction of this timescale. Chordates (a group that includes vertebrates) and echinoderms (like starfish ...
