Scientists uncovered a key genetic pathway in the origin of feathers, but they found that evolution is stubborn in turning ...

While a transient over-expression of the gene can permanently turn feet scales into feathers, it is much harder to disrupt ...

Inhibiting the sonic hedgehog (Shh) pathway strongly perturbs feather development in chickens by restricting feather bud ...

From two weeks onwards, feather development in the embryos partially returned to normal. The chicks with the altered pathway ...

Snakes are one of the most dangerous yet fascinating reptiles. With their stunning patterns, slithering noises and poisonous ...

Feathers are complex skin structures, and their evolutionary beginnings are still a subject of scientific debate. Scientific ...

Alteration of the expression of the co-called 'Sonic Hedgehog' gene can transform feet scale and wing feathers. While a transient over-expression of the gene can permanently turn feet scales into ...

Using an unbiased approach, this important study discovered a role of Ezh2 in the differentiation of granule neuron precursors, the cell of origin for Shh group of medulloblastoma. Furthermore, the ...

Scientists now believe that feathers didn’t just appear suddenly in birds. Instead, they evolved step by step from much ...
