From the Chicago Tribune, April 23, 2019: Over the weekend, the first baby bison of the spring was born to the herd at Fermilab. Fermilab may be known for its cutting-edge scientific work, but its first director, Robert Wilson, always wanted to be reminded of his home in Wyoming where he lived before moving to Batavia, and so he brought bison with him.

From WBBM Newsradio, April 23, 2019: A baby bison was born Saturday at Fermilab — the first baby born this year. Fermilab expects between 12 and 14 new calves this spring. The new baby, and its mother, are doing well.

From Physics World, April 23, 2019: Fermilab Archivist Valerie Higgins discusses how the contributions of support staff should not be forgotten when it comes to celebrating scientific breakthroughs. Modern scientific research is often conducted through large organizational structures and thousands of participants. For archivists and others interested in the history of scientific research, developing a complete picture requires an understanding not only of the work that scientists and technical staff do but also the contributions of support staff too.

Can a theory that isn’t completely testable still be useful to physics? What determines if an idea is legitimately scientific or not? This question has been debated by philosophers and historians of science, working scientists, and lawyers in courts of law. That’s because it’s not merely an abstract notion: What makes something scientific or not determines if it should be taught in classrooms or supported by government grant money.

On Saturday, April 20, baby bison season officially began. The first calf of the year was born in the early morning hours, and mother and baby are doing well. Fermilab is expecting between 12 and 14 new calves this spring, and all of our neighbors are welcome to come on site to see and photograph the newborns.

Scientists think that, under some circumstances, dark matter could generate powerful enough gravitational waves for equipment like LIGO to detect. Now that observatories have begun to record gravitational waves on a regular basis, scientists are discussing how dark matter—only known so far to interact with other matter only through gravity—might create these gravitational waves.

From Windy City Live, April 17, 2019: Romanieo Golphin Jr. is a global scientific ambassador to CERN, and he’s only nine years old! He stopped by the Windy City Live Science Lab to share some of his favorite science experiments and mentions his visit to Fermilab in this 9-minute video.

From The Beacon-News, April 18, 2019: The 12th annual STEM Career Expo at Fermilab allowed high school students interested in careers in math and science to interact with scientists at the lab and other professionals. More than 30 local companies and research organizations were represented at the event.

One of the latest discoveries from the LHC takes the properties of photons beyond what your electrodynamics teacher will tell you in class. For most of the year, the LHC collides protons, but for about a month each fall, the LHC switches things up and collides heavy atomic nuclei, such as lead ions. The main purpose of these lead collisions is to study a hot and dense subatomic fluid called the quark-gluon plasma, which is harder to create in collisions of protons. But these ion runs also enable scientists to turn the LHC into a new type of machine: a photon-photon collider.

Fermilab scientists are preparing for future, high-power particle beams with a technological advance inspired by spinning sugar. It’s a new type of target — the material that beams collide with to produce other particles, such as neutrinos. The target is designed to be able to withstand the heat from high-intensity beams, expanding the potential of experiments that use them. Researching this new patent-pending technology already has led to a TechConnect Innovation Award and might have applications in the medical field.
