Researchers in Japan led by the RIKEN Center for Biosystems Dynamics Research, Kobe and Osaka Metropolitan University, Osaka, have discovered that whale shark vision has uniquely temperature-dependent adaptations unseen in ...
Researchers at Tel Aviv University have developed a hybrid micro-robot, the size of a single biological cell (about 10 microns across), that can be controlled and navigated using two different mechanisms—electric and magnetic. ...

Scientists from Denmark and China have estimated germline mutation rates across vertebrates by sequencing and comparing genetic samples from 151 mother, father, and offspring trios from 68 species of mammals, fishes, birds ...
Different cell types—say, heart, liver, blood, and sperm cells—possess characteristics that help them carry out their unique jobs in the body. In general, those characteristics are hard-wired. Without intervention, a ...
