have been installed along ’s beachfront, injecting new life into the shoreline during the Canadian city’s winter months. Completed as a result of the annual , the six projects responded to this year’s theme of “Migration,” which sought installations that engaged with “complex social issues that surround humanity’s shaping of our global society, the flight of animals and the exchange of ideas."

Most reptiles and fish have multiple sets of teeth during their lifetime. However, most mammals, such as humans, have only one set of replacement teeth and some mammals, like mice, have only a single set with no replacement. This diversity raises both evolutionary questions -- how did different tooth replacement strategies evolve? -- and developmental ones -- which mechanisms prevent replacement teeth in animals that lost them?

A witness told authorities a gate blocked by a ball at a North Carolina animal preserve allowed a lion to reach three people cleaning an enclosure and begin a fatal attack, biting one intern's ankle and pulling her into the enclosure, according to a medical examiner's report.

Aggressiveness among animals may increase the longer individuals live together in stable groups. The study used the Amazon molly, a naturally clonal fish species that produces genetically identical individuals to isolate the effects of familiarity on behavior.

Animal experiments have shown that caloric restriction causes cellular changes that can prevent diseases.

Researchers have demonstrated that a peripheral nerve injury can trigger the onset and spread of the disease in an animal model of ALS.

According to new research published in the journal Nature Ecology & Evolution, land animal diversity has been similar for at least the last 60 million years, since soon after the extinction of the dinosaurs. “Our work provides an example of the combined power of the fossil record and modern statistical approaches to answer major questions [...]
