When a person gets a PET scan to find tumors and see how much cancer has spread, the machine is actually detecting sugar. This is because cancer has a sweet tooth, and this discovery, called the Warburg effect, could help us create better medicines and treatments for cancer. To learn more about how PET scans […]

South Korean scientists have allegedly created a superconductor that works at room temperature and regular pressure. This is a big deal because superconductors transmit electricity with zero resistance and have special magnetic properties that are very useful in technology. Normally, superconductors require extreme cold temperatures, but this new one can apparently work outside the lab […]

Researchers have successfully pinpointed the processes responsible for causing gray hair and conducted experiments aimed at its reversal. Surprisingly, some of these potential solutions have been available for several decades. Watch this episode of SciShow to learn more about how one day, people with grey hair could go reverse their greying condition.
