Storage space on an iPhone is definitely at a premium, what with the quality and size of photos and videos increasing all the time and our photo libraries now stretching back years. If you use iCloud ...

There is a new sorting algorithm a deterministic O(m log2/3 n)-time algorithm for single-source shortest paths (SSSP) on directed graphs with real non-negative edge weights in the comparison-addition ...

If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle the easiest pieces first. But this kind of sorting has a cost.

When it comes to tipping points, one of the greatest worries is the status of what is known as the Atlantic Meridional Overturning Circulation, or AMOC—a key player in making the northern part of ...
