Ultrafast Camera Takes 1 Trillion Frames Per Second of Transparent Objects and Phenomena

Emily Velasco
Lihong Wang has adapted his picosecond imaging technology to take pictures and video of transparent objects like cells and phenomena like shockwaves.
A blue dot on a black background spreads outward, indicating an expanding shockwave in water.

From the Break Through Campaign: What Makes Up a Mind

Since his years as a Caltech graduate student,Ralph Adolphs has wanted to learn how the biological brain produces the intangible mind, what the mind’s basic elements are, and how the two influence each other.

Visualizing DNA Labels in Cells and Tissues

Lori Dajose
A new bioengineering technique uses imaging to enable readout of the DNA barcodes of individual cells directly within tissues. This will allow researchers to combine information about the history of the cells, their present state, and their spatial position.

Coming to a Head: Insights from a Vampire of the Deep

Alison Koontz
Vertebrates, from fish to humans, have a backbone and a large head that includes jaws for efficient eating. By studying primitive jawless vertebrates, Caltech scientists show that gradual, progressive alterations to a cell type called the neural crest added new features, producing an ever-improving head.
