Collectively carrying a heavy load is a hard task and in fact is rarely seen outside ants and humans. Conflicts within the group must be suppressed to succeed with efficient collective transport. However, conformism may render the system unresponsive to new information. Collective transport by ants ...

Cell spreading and motility on an adhesive substrate are driven by the active physical forces generated by the actin cytoskeleton. We have recently shown that coupling curved membrane complexes to protrusive forces, exerted by the actin polymerization that they recruit, provides a mechanism that can ...

Cell motility is fundamental to many biological processes, and cells exhibit a variety of migration patterns. Many motile cell types follow a universal law that connects their speed and persistency, a property that can originate from the intracellular transport of polarity cues due to the global act ...

Migratory cells use distinct motility modes to navigate different microenvironments, but it is unclear whether these modes rely on the same core set of polarity components. To investigate this, we disrupted actin-related protein 2/3 (Arp2/3) and the WASP-family verprolin homologous protein (WAVE) co ...

Protrusions at the leading-edge of a cell play an important role in sensing the extracellular cues during cellular spreading and motility. Recent studies provided indications that these protrusions wrap (coil) around the extracellular fibers. However, the physics of this coiling process, and the mec ...

I will review the different components of the climate system and try to demonstrate why its behavior is very hard to predict. I will then continue discussing the relative roles of anthropogenic and solar climate driving, and its implications to future climate change (which is not as bleak as most of ...

We define a probe to be a single action sequence computed greedily from
a given state that either terminates in the goal or fails. We show that
by designing these probes carefully using a number of existing and new
polynomial techniques such as helpful actions, landmarks, commitments,
and consistent ...

The regulation of cellular protein levels is a complex process involving many regulatory mechanisms. These regulatory mechanisms introduce a cascade of stochastic events leading to variability of protein levels between cells. Previous studies have shown that perturbing genes involved in transcriptio ...

In this study, we develop methods to identify verbal expressions in social media streams that refer to real-world activities. Using aggregate daily patterns of Foursquare checkins, our methods extract similar patterns from Twitter, extending the amount of available content while preserving high rele ...

In recent years, huge progress in experimental flavor physics and CP violation was achieved. It led to significant progress in our theoretical understanding. In particular, it was proven that the Kobayashi-Maskawa mechanism is the dominant source of the observed CP violation. Yet, two flavor puzzles ...
