A new generation of tabletop accelerators has the potential to accelerate electrons to near the speed of light, without the need for gigantic machines like the Large Hadron Collider. But that all-important energy beam is too spread out for optimal performance. An international team of physicists has figured out a way to address this shortcoming and described their method in a new paper in Physics of Plasmas.

Predicting the future is near impossible -- but that doesn‘t stop us all from having a red hot go. Human beings have been predicting the future since the beginning of history and the results range from the hilarious to the downright uncanny.

One thing all future predictions have in common: they‘re rooted in our current understanding of how the world works. It‘s difficult to escape that mindset. We have no idea how technology will evolve, so our ideas are connected to the technology of today.
