A new study finds that low concentrations of the chemical methylisothiazolinone has subtle but measurable negative effects on the neural development of tadpoles. The chemical is found in some ...

Organisms living in seasonal environments are often limited by the time available to complete their development. Especially individuals in northern populations may face severe time constraints in ...

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 ...

Previous studies have shown how the thyroid hormone receptor alpha plays a key function in hind limb development in frogs. Using advanced gene mutation technology, scientists have been able to mutate ...

Amphibians face increasing risks from habitat loss, climate change, pollution and emerging diseases. One such disease, ranavirus, has been linked to mass die-offs of frogs and salamanders worldwide.

New research sheds light on a phenomenon called neuroplasticity. You could say Hollis Cline's lab at The Scripps Research Institute is building better tadpoles. To better understand how humans learn, ...

Couch's spadefoot toads (Scaphiopus couchii) breed in ephemeral desert ponds that are highly variable in duration. Rapid development is expected to be advantageous in short-duration ponds, but slower ...

Heritability characteristically shows large variation between traits, among populations and species, and through time. One of the reasons for this is its dependence on gene frequencies and how these ...

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 ...

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 ...

Though seemingly docile creatures, tadpoles can get snippy when hungry, and sometimes end up eating each other when the stakes are high. Now, new research suggests that the tiny creatures are not ...

Strawberry poison frogs (Oophaga pumilio) don’t create their own poison. The Central American frogs sequester the alkaloid chemicals from the mites, ants and other arthropods they eat and store it in ...
