Past Events

Electron microscopes achieve sub-Å spatial resolution through the introduction of the cold field-emitter and aberration correction optics. It is the interplay between atomic-scale structure and the associated ultrafast dynamics that governs the macroscopic functionality observed in matter. Ultrafast electron probe...

The Event Horizon Telescope (EHT) is an experiment that is being performed on a global array of millimeter wavelength telescopes that span the Earth from Hawaii to Chile and from the South Pole to Arizona. With the full array, it...

In recent years X-ray free-electron lasers (XFELs) have increased by ten or more orders of magnitude in coherence and brightness. XFELs allow for the first time the exploration of the structure and dynamics of atomic, molecular, and high energy density...

The quality, scope, and impact of U.S. science and technology is admired the world over. International scientific collaborations highlight key values including evidence, peer review, transparency, teamwork, and dialog. Scientific leadership and technological prowess are also elements of national power...

On the eve of Kepler's launch in 2009, astronomers knew of a few hundred planets orbiting other stars in the Milky Way. Today, the discoveries spill into the thousands, and the sensitivity boundaries continue to expand. NASA's Kepler Mission unveiled...

Retinal prostheses represent an exciting development in science, engineering, and medicine - an opportunity to create devices that exploit our knowledge of neural circuitry in order to replace or even enhance normal function. The lessons we learn in developing them...

Earthquake ground-motion data and magnitude-distance attenuation relationships, coupled with earthquake recurrence statistics and fault models, are the basis for our seismic hazard maps and building codes. Seismic hazard maps are constructed in a probabilistic sense for a given rate of...

As microelectronics technology nears the end of exponential growth over time, known as Moore’s law, there is a renewed interest in new computing paradigms such as quantum computing. A key step in the roadmap to build a scientifically or commercially...

Cryo-electron microscopy (cryo-EM) is technique capable of visualizing challenging systems that otherwise defy structural characterization, as it overcomes the need for crystallization, requires only small amounts of sample, and has the potential to deal with and describe compositional and conformational...
