Some countries no longer require you to remove your shoes when passing through security – but taking out your laptop is still mostly required.
Academic rigor, journalistic flair

Your brains can perceive some electromagnetic waves – but not without your body’s help.
Our new study demonstrates the enormous potential that machine learning has to help identify people with AS
Vegan wool, peanut coats and the discovery of DNA: the forgotten life of scientist William Astbury
Florence Bell’s work producing X-rays of DNA laid the foundations for one of the landmark discoveries of 20th century science.
Despite the name, some black holes effectively “shine” as they suck up nearby material with such force that it begins to glow. New research reveals a new method for detecting these active black holes.
The landscape artist bravely left her aristocratic life behind to help save lives on the Italian front.
Artificial intelligence holds great promise for medicine, but safeguards are needed to ensure it does not harm patients.
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?
With its strange bluish glow and cancer-killing qualities, meet the wundermetal that became one of the great cautionary tales of modern times.
Astronomers found something not predicted by current theory when they took a closer look at the emissions from a neutron star with a very strong magnetic field.
Could Canadian technology play a part in the newly announced U.S. Space Force? A team at McMaster University has developed an instrument that could keep Space Force troops safe from radiation.
An X-ray sensitive ink means future detectors could be printable, portable and flexible.
If an undocumented migrant is a minor or an adult can have far-reaching implications. A forensic anthropologist explains why relying solely on dental X-rays to determine age doesn’t work.
The little-known Rossi X-ray Timing Explorer spacecraft was like a Geiger counter for the universe, listening to black holes and zombie stars.
There could be thousands of black holes at the heart of the Milky Way.
Human eyes don’t have x-ray vision. But we can use radiography machines to allow our eyes to see inside things the human eye cannot.
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.
Getting the right amount of radiation is a fine balance between therapy and harm. A common way to improve the benefit-to-cure ratio is to fire multiple beams at the tumour from different directions.
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?
