If a hydra is beheaded, a new organizer can form and prompt the animal to regrow its head. Meanwhile, the head that was lopped off will sometimes regrow the lower portion of its body.
Hydra vulgaris constantly replenish the cells in their heads and grow new ones to reproduce asexually. But gene expression analyses reveal that regenerating a head after an injury is a very different ...
Once established, governmental organizations never get the ax. They don't even die in their sleep. Like the Hydra, they grow more heads, claim new purposes for themselves and flourish. As Claudia ...
A new study suggests that stretchy skeletal structures play a crucial role in helping hydras (Hydra vulgaris shown) regrow their heads in the right place. Proyecto Agua/Flickr (CC BY-NC-SA 2.0) ...
New research describes how real-life hydra can use epigenetics to regenerate their heads, rendering them effectively immortal.
The researchers then compared gene expression during head regeneration with gene expression during budding, a form of asexual reproduction where a hydra grows a polyp that is basically a copy of ...
One day, a group of wise sages came to the kingdom and proposed a new way of securing the kingdom's communications using a new type of encryption called post-quantum cryptography.
This hydra grows heads out of its other heads, and to kill it, you need to cut off the shortest head branches, lest it regrow that entire section twice (which it does any time you cut off a head ...
Hercules, the Greek mythological hero, was tasked to pursue and defeat the Hydra. The battle of the Hydra proved difficult; when a head was severed, then more heads would grow in its place.
The researchers found that when the animals were confined lengthwise, the result was a regeneration of two heads and often more than one foot. The discovery calls back to Greek mythology, in which ...
The researchers found that when a hydra needs a new head, it releases Wnt3 that clings to beta-catenin/TCF, which then activates a bunch of genes that include more Wnt3 and Sp5.
