Skoltech researchers have shown genes involved in embryonic development to be at work in pupation—the drastic transformation that butterflies and some other insects undergo as their larvae mature. The discovery furthers ...

Can algae talk? "Well, although they don't have any mouth or ears, algae still communicate with their own kind and with other organisms in their surroundings. They do this with volatile organic substances they release into ...

Germ cells, the reproductive cells that eventually become eggs and sperm, are set aside early in embryonic development, when the embryo is just a hollow ball of cells called the gastrula. This means that the cells transferring ...

The phenomenon of regeneration was discovered over 200 years ago in the freshwater polyp Hydra. Until now, however, it was largely unclear how the orderly regeneration of lost tissues or organs is activated after injury. ...

The first mutation of the wingless gene was found by accident in Drosophila in the 1970s, following the observation of flies that did not possess wings, hence its name. Fifteen years after its discovery, the gene was found ...
