Young hockey players who have suffered concussions may still show changes in the white matter of the brain months after being cleared to return to play, researchers at Western University have found through sophisticated Magnetic Resonance Imaging (MRI) techniques. “During the early teen years, the brain is still not fully developed and as it continues to grow and mature, it …

There are currently about fifty known exoplanets with diameters that range from Mars-sized to several times the Earth’s and that also reside within their stars’ habitable zone – the orbital range within which their surface temperatures permit water to remain liquid. A “water world” is an extreme case, an exoplanet defined as being covered by a deep ocean, perhaps as …

Interest in “Properties of Expanding Universes” is at an all-time high: Stephen Hawking’s doctoral thesis of that name crashed Cambridge University’s open-access repository on the first day the document was posted online. When an unknown physics student submitted his completed PhD thesis in 1966 he had no idea thousands would still be clamouring to read it more than 50 years …

Plastic in our seas is threatening coral, which researchers now believe may see it as tasty food. There are fears for the future of coral, such as the Great Barrier Reef, which stretches for 1,400 miles off the coast of Australia. “Corals in our experiments ate all types of plastics but preferred unfouled microplastics by a threefold difference over microplastics …

Researchers has discovered a new set of footprint fossils that suggests a large carnivorous dinosaur roamed southern Africa around 200-million years ago. The footprints belong to a new species, named Kayentapus ambrokholohali*, which is part of the group of dinosaurs called “megatheropod”. The term “Megatheropods” describes the giant two-legged carnivorous dinosaurs, such as the iconic Tyrannosaurus rex (T. rex) which …

Scientists have revealed a nature-inspired RoboBee that can dive into water mid-flight, and launch itself back out for a safe landing. The design uses a ‘Goldilocks combination’ of wing size and flapping rate, allowing for a system that’s 1,000 times lighter than any other aerial-to-aquatic robot, according to the creators. Once it dries off, the “robo-bee” can repeat the whole …

There’s something endearing about the crooked, gapped-tooth smiles of children whose permanent teeth are coming in. While it’s normal for adult teeth to show up at very different times, should we expect the same good oral health conditions for all children at all times? In Québec there has been no impact study on oral health promotion since provincial guidelines were …

New study at the University of Adelaide has found that a specific combination of techniques will increase people’s chances of having lucid dreams, in which the dreamer is aware they’re dreaming while it’s still happening and can control the experience. Although many techniques exist for inducing lucid dreams, previous studies have reported low success rates, preventing researchers from being able …

Footage of a mysterious moth-like insect flexing its pulsating tentacles has whipped the internet into a frenzy. The video shows what appears to be a moth with a huge orange belly. Attached to it are four enormous hairy tentacles which it is seen flexing in the air. Thousands of people reacted in horror after the footage was shared on Facebook …

Nissan was one of the first global automakers to put a full battery-electric vehicle in the market, but it’s been slower than some to expand that expertise into other market segments. This year’s Tokyo motor show suggests that’s all about to change, with the second-generation Nissan Leaf making its debut, alongside a Nismo-prepared variant and this – the IMx concept. …

Already rapidly disappearing Arctic sea ice is melting up to 25 per cent more quickly than initially believed, according to research conducted partly by University of Calgary researchers. Indeed, scientific predictions that foresaw the first ice-free Arctic Ocean in the summertime occurring between 2040 and 2050 may come to pass even sooner, according to Vishnu Nandan, Geography Eyes High doctoral …
