Tooting our horn: Fermilab has the most expertise in constructing neutrino horns, which focus the particles that eventually decay into neutrinos. Learn how they work.

Fermilab’s house photographer of almost 30 years, Reidar Hahn, shares four of his most iconic shots.

From Science News, Aug. 11, 2016: Particle physicists, including Fermilab Director Nigel Lockyer, scrutinize latest LHC results to refine knowledge of the Higgs boson’s properties.

Fermilab’s TRAC program helps middle and high school teachers turn lab experiences into lessons or exercises for their students.

From Berkeley Lab, Aug. 9, 2016: DESI, the Dark Energy Spectroscopic Instrument, will measure light from 35 million galaxies to provide new clues about dark energy. Fermilab is a collaborator on the Berkeley Lab project.

How do scientists know what percentages of the universe are made up of dark matter and dark energy? Cosmologist Risa Wechsler of the Kavli Institute for Particle Astrophysics and Cosmology explains. Watch the 3-minute video.

The IceCube experiment reports ruling out to a high degree of certainty the existence of a theoretical low-mass sterile neutrino.

From the Kane County Chronicle, Aug. 3, 2016: When the Fermilab Natural Areas organization does habitat restoration, it means more than just pulling weeds. Volunteers may also end up learning about ecology.

From Nature, Aug. 5, 2016: The intriguing data “bump” at the Large Hadron Collider — first reported in December — turns out to be nothing more than a statistical fluctuation.

NOvA scientists have seen evidence that one of the three neutrino mass states might not include equal parts of muon and tau flavor, as previously thought. Scientists refer to this as “nonmaximal mixing,” and NOvA’s result is the first hint that this may be the case for the third mass state.
