Andrea Foster uses x-rays to determine the forms of potentially toxic elements in environmentally-important matrices such as water, sediments, plants, and microorganisms. In this free public lecture, Foster will discuss her research on arsenic, which is called the silent killer...

Archimedes (287-212 BC), who is famous for shouting 'Eureka' (I found it) is considered one of the most brilliant thinkers of all times. The 10th-century parchment document known as the “Archimedes Palimpsest” is the unique source for two of the...

The enigmatic neutrinos are among the most abundant of the tiny particles that make up our universe. They are a billion times more abundant than the particles of which the earth and we humans are made. Thus, to understand the...

According to Smith, protein crystallography allows scientists to design drugs in a much more efficient way than the standard methods traditionally used by large drug companies, which can cost close to a billion dollars and take 10 to 15 years...

When we explore Nature at distances much smaller than the size of an atom, we find new and mysterious physical principles. At such small sizes, particles are governed by "quantum theory". Quantum theory tells us that some aspects of particle...

Most people have intuitive associations with the word "magnetism" based on everyday life: refrigerator magnets, the compass, north and south poles, or someone's "magnetic personality". Few people, however, realize how complicated the phenomenon really is, how much research still deals...

The Universe appears to be flat, accelerating and lightweight. In this talk, I will explain what these terms mean, how we developed this view and its implications. I will also discuss the connection between cosmology and particle physics experiments being...

In our normal everyday lives we are exposed to an incredibly complex chemical soup consisting of an enormous variety of different chemical compounds. Many of these compounds contain metal atoms which, once inside us, can either fulfill roles that are...

Half of our universe appears to be missing, and scientists at SLAC and all over the world are trying to understand why. Don't miss this talk in which Steve Sekula will explain the core issues surrounding matter and anti-matter.
