Automated patch clamp electrophysiology of neurons in the living brain
Whole-cell patch clamp electrophysiology of neurons in vivo enables the recording of electrical events in cells with great precision, and supports a wide diversity of cellular morphological and molecular analysis experiments. However, high levels of skill are required in order to perform in vivo patching, and the process is time-consuming and painstaking. An automated in vivo patching robot would not only empower a great number of neuroscientists to perform such experiments, but would also open up fundamentally new kinds of experiment enabled by the resultant high throughput. We discovered that...

Circadian rhythms of the microscopic green alga Ostreococcus tauri: a robust and flexible clock in all weather and seasons
Circadian clocks rely on the alternation of light and dark to synchronize to the day/night cycle. However, a consequence of weather fluctuations and seasonal variations is that the driving signal received by the clock is highly variable not only from one day to the next but also throughout the year, which may compromise robust entrainment. The microscopic green alga Ostreococcus tauri has recently emerged as a promising circadian model in the green lineage. Its clock is based on a central loop featuring orthologs of Arabidopsis TOC1 and CCA1 clock genes, yet seems to have a simpler architecture than Arabidopsis. The...

Understanding an hourglass, and other granular flows in under an hour
Flows of particulate material, such as sand discharging in an hourglass, are ubiquitous in nature and industry. The flow and transport of granules, powders, or grains is complex and can differ considerably from that associated with a single-phase material. This presentation will highlight some unique features of granular materials (such as the discharge from an orifice) and describe some recent work at Caltech on wave propagation, booming sand dunes, and granular flow rheology.

Unraveling Knotted Fields
To tie a shoelace into a knot is a relatively simple affair. Tying a knot in a field is a different story, because the whole of space must be filled in a way that matches the knot being tied at the core. The possibility of such localized knottedness in a space-filling field has fascinated physicists and mathematicians ever since Kelvin’s 'vortex atom' hypothesis, in which the atoms of the periodic table were hypothesized to correspond to closed vortex loops of different knot types. Perhaps the most...
