Modern forensics can detect a single cell deposited at a crime scene, but it cannot tell us how or when it got there. In this video, we explore vulnerabilities, human biases, and systemic flaws hidden within the forensic field we trust to deliver justice.

Do twin primes go on forever? It seems like a simple question, but proving something in mathematics is tricky, especially the twin prime conjecture.In 2013 however, there was a big break through. Not from one of the world's top mathematicians, but from a professor at the University of New Hampshire... who used to be a subway worker!If you’re looking for a molecular modelling kit, try Snatoms, a kit I invented where the atoms snap together magnetically - https://ve42.co/SnatomsV Sign up for the Veritasium newsletter for weekly science updates - https://ve42.co/Newsletter For early access to work in progress videos join our patreon https://ve42.co/VePatreon

Something is disrupting GPS signals across Europe. After noticing this disruption two scientists, Professor Todd Humphreys and Dr Zach Clements at the University of Texas at Austin, went on a hunt to find the source of this jamming.This is the story of how they tracked it down. If you want to read their full paper (out today!) click the link below! Clements, Z. L., Kriezis, A., & Humphreys, T. E. (2026).

Tap to pay is one of the most widely used ways of paying in the world. But it has one tiny flaw which if exploited can let you steal a lot of money from a locked phone. Here is how we hacked MKBHD and stole $10,000!▀▀▀If you’re looking for a molecular modelling kit, try Snatoms, a kit I invented where the atoms snap together magnetically - https://ve42.co/SnatomsV Sign up for the Veritasium newsletter for weekly science updates - https://ve42.co/Newsletter

Antimatter is the world's most volatile substance. When it comes into contact with matter they annihilate producing photons and energy. (This is due to Einstein's E=mc^2)There is only one factory in the world that makes it and it's at CERN. We went inside to find out how it works and why they're making it...

The history of credit cards has been a battle between speed and security. How can banks make you spend more without worrying about fraud or theft?In comes tap to pay, which now accounts for approximately for 45% of the world's purchases each year.But how does it work and what does it have to do with espionage during the Cold War?We dissolved a credit card in acetone to find out.

Newcomb's Paradox is a problem in decision theory where both answers seem equally obvious to those on each side.Your choice of one box or two says a lot about the way you make decisions and the way you view the world. Can you choices now affect a predetermined outcome? What does this say about free will? And what is the ultimate strategy to beat the supercomputer, is it even possible?
