Physicists in the US have created an optical frequency comb that operates in the extreme ultraviolet (XUV). Touted as the first practical comb to work in this region of the spectrum, the device could ...

Harvard John A. Paulson School of Engineering and Applied Sciences Nature has a way of finding optimal solutions to complex problems. For example, despite the billions of ways for a single protein to ...

Russian physicists are building their first klystron generator, a critical particle accelerator component for which the country has previously had to rely on external suppliers in Europe or Japan. Now ...

This is the second article in a series. Since the advent of stealth technology, claims have abounded about ways low-observable aircraft can be detected. Chief among these are radars that operate at ...

Nature has a way of finding optimal solutions to complex problems. For example, despite the billions of ways for a single protein to fold, proteins always fold in a way that minimizes potential energy ...
