Quick Take Boulenger’s backpack frog carries eggs in a dorsal pouch on its back instead of dropping them into water. This ...

Flexible electrodes were implanted into tadpole embryos when they were days old - Liu Lab/Harvard School of Engineering and Applied Sciences Cyborg tadpoles with electrodes grown into their brains ...

Bioengineering researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have developed a soft, thin, stretchable bioelectronic device that can be implanted into a ...

Deep in the Peruvian rainforest, a brilliantly colored frog lays one hand gently on top of a small clump of gelatinous eggs. Using his delicate sense of touch, he’s feeling for the embryos inside.

Scientists have newly described three extraordinary species of tree toad that leapfrog over the egg-to-tadpole stage. The females give birth on land to dozens of toadlets, each measuring just a few ...

Early brain development is a biological black box. While scientists have devised multiple ways to record electrical signals in adult brains, these techniques don’t work for embryos. A team at Harvard ...

1. High-latitude species (and populations within species) are adapted to short and cold summers. They often have high growth and development rates to fully use the short growing season and mature ...

With 8.2 billion people in the world, cities are constantly expanding, rapidly altering the environment. Animals that undergo complete metamorphosis, such as frogs, may face bigger challenges as they ...
