Study shows Aussie dingo may be world's oldest dog

A rare shark couple found for the first time off the coast of Australia may force a rethink of the species' range.

Modern dogs were around 33,000 years ago, a new fossil analysis suggests. Researchers tested the DNA of a tooth from a skull found in southern Siberia that they were able to confirm it was more closely related to modern dogs than to wolves.

TORONTO — Many Torontonians are going vegan, and that includes the four-legged ones. Vegan diets for dogs are becoming increasingly prevalent in Toronto as owners who follow the vegan lifestyle are implementing it on their pets. Ken Butland, 35, is a vegan who is passionate about his lifestyle and wanted to pass it down to his two dachshunds.

Scientists in Britain on Wednesday announced a breakthrough in the quest to turn DNA into a revolutionary form of data storage. A speck of man-made DNA can hold mountains of data that can be freeze-dried, shipped and stored, potentially for thousands of years, they said. The contents are "read" by sequencing the DNA -- as is routinely done today, in genetic fingerprinting and so on -- and turning it back into computer code.

Last month, North Americans were shocked at revelations of widespread fraudulent labelling of seafood. Oceana, the world’s largest marine conservation organization, surveyed seafood products being sold in American stores and restaurants, and found a third of over 1,200 samples were not as advertised, and almost half of the 674 retail outlets screened were selling mislabeled fish. Snapper was found to be tilapia; Atlantic cod was white hake; white tuna was escolar.

TORONTO — Viruses closely related to the new coronavirus that emerged last year in the Middle East have been discovered in specimens from a number of species of bats found widely throughout Europe and beyond, a new study shows. The work suggests bats common to Europe, Russia, parts of Asia and Africa and the Middle East may carry viruses that are very closely related to the new coronavirus, called EMC 2012. The study will be published in the March issue of the journal Emerging Infectious Diseases.

A new study in the journal Science today shows just how easy it is to link anonymous genetic data to an actual person. By using publicly available databases and resources, the researchers were able to identify the donors of anonymous genetic sequences.
