Two-dimensional nanomaterial sets expansion record

It is a common hack to stretch a balloon out to make it easier to inflate. When the balloon stretches, the width crosswise shrinks to the size of a string. Noah Stocek, a Ph.D. student collaborating with Western physicist ...

Making ultra-fast electron measurements in multiple directions to reveal the secrets of the aurora

The energetic electrons that drive the aurora borealis (the northern lights) have a rich and very dynamic structure that we currently do not fully understand. Much of what we know about these electrons comes from instruments ...

Charting the night sky with exascale computers

Creating multiple universes to see how they run might be tempting to scientists, but it's obviously not possible. That is, as long as you need physical universes. If you can make do with virtual ones, there are far more options.

Eclipse chasers head to southern Illinois for 2nd total solar eclipse in 7 years

In 1999, Michelle Nichols saw her first total solar eclipse on a cruise in the Black Sea. It would be many years before she witnessed another one during a visit to southern Illinois in 2017.
