Ghost particles: how galaxies helped us weigh the lightest neutrino – and why it matters

Even when you close your eyes at night, 100 billion neutrinos produced in the sun will pass through them – travelling close to the speed of light, but never hitting anything. Neutrinos are extremely elusive and only weakly interact with matter around them: nature’s true ghosts. Until very recently, these tiny particles were believed to…

Researchers produce first-ever videos of chemical synthesis at atomic resolution

Electron microscope images of the test sample at different magnifications. Credit: (c) 2019 Nakamura et al. For the first time, researchers have managed to view previously inaccessible details of certain chemical processes. They have shown there are significant discrete stages to these processes that build on existing knowledge of chemical synthesis. These details could aid…

A Rail Gun the Size of Manhattan Could Reveal the Secrets of the Higgs Boson

(Image: © Shutterstock) Nobody messes with the Large Hadron Collider. It’s the supreme particle smasher of the present age, and nothing can touch its energy capabilities or ability to study the frontiers of physics. But all glory is transitory, and nothing lasts forever. Eventually, somewhere around 2035, the lights at this 17-mile-long (27 kilometers) ring…
