Discovery of fastest ever magnetic wave propagation

Like light waves, magnetic waves move through materials at a fixed maximum velocity. However, at the smallest possible length scale (nanometres) and the shortest possible time scale (femtoseconds), magnetism behaves differently. ...

Autonomous nanomachines inspired by nature

Inspired by the way molecules interact in nature, UNSW medical researchers engineer versatile nanoscale machines to enable greater functional range.

The origin of life in an RNA pocket

This story begins several billion years ago. There's only chemistry, no biology—that is, plenty of chemical compounds exist on Earth, but life hasn't yet emerged. Then, among myriads of randomly self-assembled chemical ...

Implications of no-free-lunch theorems

In the 18th century, the philosopher David Hume observed that induction—inferring the future based on what's happened in the past—can never be reliable. In 1997, SFI Professor David Wolpert with his colleague Bill Macready ...
