Past Events

Supercomputer performance now exceeds that of the earliest computers by thirteen orders of magnitude, yet science still needs more than they provide.  Prior to 1990, supercomputers were powered by one, or a few, sequential or vector processors.  But since 1990...

I present a new measurement of the positive muon anomalous magnetic moment a_μ=(g_μ-2)/2  from the Fermilab E989 experiment.    The quantity a_μ  is an exquisite probe of the quantum corrections of the muon interaction with the electromagnetic field.  The experiment...

I will describe the LHCb experiment that studies decays of b quarks (mass of 5 GeV), and charm quarks (1.5 GeV), and show how studying these particles we are sensitive to physics and new particles at very large mass scales...

In 2017 April, the Event Horizon Telescope (EHT) observed the near-horizon region around the supermassive black hole at the core of the M87 galaxy. These 1.3 mm wavelength observations revealed a compact asymmetric ring-like source morphology. This structure originates from...

While it is considered to be one of the most promising hints of new physics beyond the Standard Model, dark matter is as-yet known only through its gravitational influence on astronomical and cosmological observables. I will discuss our current best...

These are extraordinary times for immunology, vaccinology, and the world. In the few short months since its emergence, the devastating impact of the SARS-CoV-2 virus has radically transformed virtually every dimension of our lives and fueled an urgent global imperative...

The demonstration of nuclear fusion in the laboratory and eventual utilization as an unlimited energy source has been a grand challenge for physicists and engineers for 70 years. All life on earth depends on this process that powers our sun...

First discovered serendipitously in 1967, the phenomena known as gamma-ray bursts - short-lived, extremely bright flashes of high-energy radiation - mystified astronomers for decades. Despite many breakthroughs, key open questions - such as the mechanism responsible for the prompt gamma-ray...

New polls show 7 in 10 Americans support legislation to eliminate fossil fuel emissions from the transportation, electricity, buildings, industry, and agricultural sectors by 2050. Then why is nuclear power — our largest and best source of carbon-free electricity in...
