On Oct. 1, 1971, Godfrey Hounsfield’s invention took its first pictures of a human brain, using X-rays and an ingenious algorithm to identify a woman’s tumor from outside of her skull.
While we know that most chameleons have such a prehensile tail, it’s not yet clear how it works and what makes it simultaneously so flexible and strong.
This is a crucial dinosaur for palaeontologists; the variety of fossils available means researchers can study the species’ growth through its whole life span.
Through science, art and technology, we are able to reconstruct the faces of the dead based on their remains. The researcher who did this work for descendants in Sutherland explains the process.
Low-dose CT scans can detect lung cancer in smokers and former smokers at an early and sometimes treatable stage. Why are so few smokers and former smokers getting them?
The more we know about the animals that lived during this time, the more we can start to comprehend how species react and recover after an extinction event.
Museums’ collections are a priceless resource for scientists, but they’re not easy to access. Digitizing specimens – like the 700 bat skulls the author studied – is a way to let everyone in.
X-rays are like light rays, but they can pass through more stuff. Some of the x-ray’s energy is blocked by bone, which is why you can see bones so clearly on x-ray scans.
In a recent study of almost 11 million young Australians, we showed those exposed to a CT scan before the age of 20 had a small increase in cancer risk in the years after exposure.
Reducing health-care waste relating to unnecessary tests has been a major priority for researchers, governments and health services for decades. But how do we change the behaviour of doctors?
