Breakthrough study examines evolution of snake venom genes

A new study from biologists at The University of Texas at Arlington and an international team of collaborators provides the first comprehensive explanation of how snake venom regulatory systems evolved—an important example ...

Important genetic origin of our senses identified

Having a head is quite an advantage. Although this may sound banal, it had to be tested in a long evolutionary process: As animal life developed, invertebrates initially dominated the oceans. These had already developed head ...

Building a human body through gastrulation

A collaboration of researchers from Japan, Spain and the U.S. offers a phylogenetic and ontogenetic overview of the primitive streak and its role in mediating amniote (vertebrate animals that develop on land) gastrulation, ...

Which animals can catch the coronavirus?

On Oct. 6, the U.S. Department of Agriculture's National Veterinary Services Laboratories announced confirmation of SARS-CoV-2—the virus that causes COVID-19—in two previously uninfected animal species at a zoo in Illinois. ...

A diversity of wildlife is good for our health

A growing body of evidence suggests that biodiversity loss increases our exposure to both new and established zoonotic pathogens. Restoring and protecting nature is essential to preventing future pandemics. So reports a new ...

All-purpose dinosaur opening reconstructed for first time

For the first time ever, a team of scientists, led by the University of Bristol, have described in detail a dinosaur's cloacal or vent—the all-purpose opening used for defecation, urination and breeding.
