T. rex had a body temperature of 36.3°C, almost the same as humans; fossil tooth chemistry reveals the 66-million-year-old predator was warm-blooded and could survive in cold climates

Representative Image via Canva For 66 million years, the body temperature of Tyrannosaurus rex (T.rex) lived only in speculation. Now, a new study has taken the dinosaur’s temperature using chemistry locked inside its fossilised teeth, finding an average of about 36.3°C (97.3°F), strikingly close to the human norm. The researchpublished in Science Advances, offers one … Read more

Norway’s Green Mountain data centre uses 8°C fjord water to cool its servers, turning a naturally cold resource into free refrigeration

Norway’s Green Mountain data centre uses 8°C fjord water to cool its servers, turning a naturally cold resource into free refrigeration

A data centre quietly produces heat every second it is operating. Behind the walls, rows of servers process data continuously, turning large amounts of electricity into computing power and, inevitably, excess heat. That heat has to be removed to keep the equipment within safe operating temperatures, adding significantly to the facility’s energy demand. Green Mountain … Read more

In 2004, Toronto began using cold water from 83 metres beneath Lake Ontario to cool downtown buildings; today the system serves 200 buildings across 40 million sq ft

In 2004, Toronto began using cold water from 83 metres beneath Lake Ontario to cool downtown buildings; today the system serves 200 buildings across 40 million sq ft

Representative Image (AI-generated) Deep beneath the surface of Lake Ontario, a layer of naturally cold water has become an unlikely part of Toronto’s urban infrastructure. Instead of relying entirely on conventional air-conditioning systems to cool its downtown buildings, the Canadian city uses the lake’s cold temperature as a source of cooling energy. According to a … Read more
