Scientists don’t yet know what dark matter is made of, but they are full of ideas.

Fermilab scientist Don Lincoln explains how particle physics research attempts to answer questions of the universe. For those with a more practical bent, he explains how this research is an excellent investment, with a high rate of return for society.

Scientists plan to use a newly awarded grant to develop a shoebox-sized particle accelerator in five years.

Although they might be invisible to the naked eye, contaminants less than a micron in size can ruin very sensitive experiments in particle physics.

The Proton Improvement Plan II, or PIP-II, is a proposed project to improve Fermilab’s particle accelerator complex with a major hardware overhaul and a powerful boost in its capabilities.

Fermilab’s popularity as a birding site is its diversity of species, a measure of the quality of the habitat. Birders have found 287 bird species at Fermilab.

Many physics degree programs excel at preparing students for an academic career, but more than half of those who complete the programs head to industry instead.
