A woman walking to a bus stop realizes that she forgot her keys; she suddenly turns around and runs home. Such spontaneous activities are hallmarks of animal behavior. Eager to capture the essence of the human brain, roboticists have tried … Continue reading

Journal Club: A new, twisted topological insulator
About a decade ago, physicists began identifying and probing materials that suffer something of an identity crisis. On the surface of these crystals, electrons flow and form currents, like in a conductor. But in the interior, electrons are pinned and … Continue reading
When to launch a cyber attack
The evolution of malicious software (“malware”) has proceeded so rapidly since the invention of the first computer virus three decades ago that the question is not whether but when a computer system will face a cyber attack. Such attacks were … Continue reading

Discovering overlapping communities in real-world networks
Naturally-occurring networks are naturally modeled as being made up of many overlapping communities — for instance, our work and friends when it comes to social networks, or those describing different protein complexes in biology. Detecting such overlapping communities is an … Continue reading
