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.

Artificial intelligence holds great promise for medicine, but safeguards are needed to ensure it does not harm patients.
Smoking is the biggest cause of preventable death in the U.S. A test for long-time smokers might be able to detect lung cancer earlier, thereby saving lives.

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?
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.
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.

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.
Radiotherapy treats cancer by directing beams of high energy x-rays at the tumour.

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.
Doctors know most scans for low back pain are useless, but they have trouble convincing patients.

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?

Cancer is not the modern disease many believe it to be. New fossil evidence from two South African caves suggests that its origins lie deep in prehistory.
