A research team at Yunnan University has resolved a longstanding mystery regarding Earth’s earliest vertebrates, revealing ...

A research team led by the Universitat Autònoma de Barcelona (UAB) has revealed how the genome is reorganized in 3D during male germ cell formation in vertebrates, leading to important new insights ...

A better understanding of neuroimmune communication is crucial for identifying conserved and divergent mechanisms across ...

The researchers from the HiLIFE Institute of Biotechnology, University of Helsinki compared two central bearded dragon lizards (Pogona vitticeps): a normal one and a mutant with no body scales. They ...

Archaea are often mistaken as bacteria, given that both are small, single-cell organisms. However, archaea are as genetically different from bacteria as humans are from bacteria. While archaea are ...

Vertebrates have extremely different brain sizes: even with the same body size, brain size can vary a hundredfold. As a rule, mammals and birds have the largest brains in relation to their body size, ...

A team of herpetologists at the Universidade Estadual de Santa Cruz just reported that a tiny frog found only in a hilltop forest in southern Bahia, Brazil, may be the smallest vertebrate in the world ...

Researchers have long assumed that a tube in the famous Pikaia fossil ran along the animal’s back. But a new study turned the fossil upside down. By Carl Zimmer Over the past 500 million years, ...

Limb formation in vertebrates begins with the emergence of a limb bud from the lateral plate mesoderm beneath the surface ectoderm. Three orthogonal signalling centres establish the fundamental axes ...

Researchers report that ancient viruses may be to thank for myelin -- and, by extension, our large, complex brains. The team found that a retrovirus-derived genetic element or 'retrotransposon' is ...

Walking is a complex mechanism involving both automatic processes and conscious control. Its dysfunction can have multiple, sometimes extremely subtle causes, within the motor cortex, brain stem, ...
