Researchers investigate evolution of bipedalism in ancient dinosaur ancestors

Researchers discovered that ancient dinosaurs inherited bipedalism from smaller proto-dinosaurs, who developed strong tail muscles. This adaptation allowed early dinosaurs to run faster and for longer distances. However, mammals lost this trait due to the need for burrowing adaptations, which required strong front limbs and short tails.

How on Earth does geotagging work?

Computing science researchers at the University of Alberta have developed a technique to automate geotagging for news articles and other online documents. The model integrates two competing hypotheses: inheritance and near-location, achieving high accuracy in matching named entities to geographical locations.

Trash that pop can, trash yourself

A study by the University of Alberta and Boston University found that people are more likely to recycle items bearing their name or a national flag. This association helps individuals link the item to their sense of identity, making them feel more connected and reducing negative feelings associated with discarding it.

Supporting life on Earth

Scientists found evidence of O2 fluctuations in Western Australian rocks, suggesting a temporary increase in atmospheric oxygen levels around 2.5 billion years ago. The data supports the 'Great Oxidation Event' theory, where multiple 'whiffs' of O2 accumulated until a tipping point was crossed.
