In Brief

Giorgio Apollinari to speak at CERN's inauguration of the International Year of Light

On Feb. 4, Fermilab scientist Giorgio Apollinari will give a talk for the public via webcast at CERN's celebration of the International Year of Light.

The year 2015 has been proclaimed the International Year of Light and light-based technologies by the United Nations General Assembly. CERN is marking the proclamation with an evening of talks beginning at 1:30 p.m. Central time on Wednesday, Feb. 4.

As director of the U.S. LHC Accelerator Research Program, Apollinari will discuss advances in particle accelerator technology and how they can transform our everyday lives in areas such as diagnostic medicine and pharmaceuticals. His talk will follow a presentation by Lucio Rossi, head of the High-Luminosity LHC project.

View the agenda, and read more about CERN's International Year of Light inauguration.

Audiences and critics in Europe and Australia agree — Cirque Zuma Zuma is unlike anything they have ever seen before.

The Fermilab Arts Series will present the rhythmic, high-energy show in Ramsey Auditorium on Saturday, Feb. 7, at 7 p.m.

Cirque Zuma Zuma features talented performers who will present 90 minutes of nonstop action and amazing feats that will keep audiences breathless. The show includes dance, pole acts, acrobatics, chair and hand balancing, tumbling, contortion and juggling. This is a great evening of fun for the whole family.

Tickets are $30, $15 for those ages 18 and under. For more information or to make reservations, visit the Fermilab Arts Series Web page or call 630-840-2787.

Speck of interstellar dust obscures glimpse of big bang

From The New York Times, Jan. 30, 2015

Scientists will have to wait a while longer to find out what kicked off the big bang.

Last spring, a team of astronomers who go by the name of Bicep announced that they had detected ripples in space-time, or gravitational waves, reverberating from the first trillionth of a trillionth of a trillionth of a second of time — long-sought evidence that the expansion of the universe had started out with a giant whoosh called inflation.

The discovery was heralded as potentially the greatest of the new century, but after months of spirited debate, the group conceded that the result could have been caused by interstellar dust, a notion buttressed by subsequent measurements by the European Space Agency's Planck satellite that the part of the sky Bicep examined was in fact dusty.

Top 10 scientific mysteries for the 21st century

From Science News, Jan. 28, 2015

The last few centuries have been pretty good for science. In the 17th century, Isaac Newton solved the ancient controversy over the nature of forces and motion with his three laws. In the 18th, Ben Franklin figured out a lot about electricity. In the 19th, Darwin explained the diversity of species, Maxwell revealed the physics of light, Mendeleyev defined the families of chemical elements. In the 20th we had Einstein, who figured out all sorts of stuff, including gravity. No to mention Watson and Crick, who deciphered the molecular foundation for genetics and life. What more do you want?

Director's Corner

Electron neutrinos from supernovae

Fermilab Director
Nigel Lockyer

Neutrino research has the potential to lead to discoveries that rival the observation of the Higgs boson. And just as with the successful search for the Higgs, the question of the nature of neutrinos is being investigated by different teams using different methods.

Here at Fermilab we are very familiar with one method — the study of neutrinos created from high-power particle accelerators. But at last month's ELBNF collaboration meeting, Duke University Professor Kate Scholberg gave a fascinating introduction to the future use of a large, deep underground liquid-argon detector (currently referred to as ELBNF) to study neutrinos from supernovae in our galaxy. In Scholberg's words:

"When massive stars run out of nuclear fuel, they collapse in on themselves, forming ultradense neutron stars and, in some cases, even black holes. Just as gravitational potential energy turns to kinetic energy when you drop an object, the vast energy of the star's infall must be released somehow. Some will be released in an enormous supernova explosion, but 100 times more is released in the form of neutrinos, particles famous for their feeble interactions with matter. Because neutrinos interact so weakly, they escape the supernova with nearly all of the collapse energy within only tens of seconds, creating an intense burst of all three flavors of neutrinos and antineutrinos with energies of a few tens of MeV.

"Neutrinos are also known for their ability to transform from one flavor to another. The time, energy and flavor evolution of the burst not only tells the story of the star's destruction and the creation of its exotic compact progeny, but will also give us insight into the properties of neutrinos themselves. The different flavors tell different stories. The electron flavor neutrinos have a particularly interesting story to tell — they are emitted in an initial flash (tens of milliseconds) as protons and electrons are squeezed together to make neutrons and are more likely to bear the signatures of explosion processes and flavor oscillations.

"On Earth we have a chance to witness the unfolding of a Milky Way core-collapse supernova by observing the neutrino burst in large underground neutrino detectors. About four explosions per century are expected. Observing the different flavor components of the burst is a bit like making a movie in different colors.

"Different kinds of detectors are sensitive to different neutrino flavors. Existing large water and scintillator detectors (such as Super-K, IceCube, KamLAND, LVD Daya Bay and Borexino) are primarily sensitive to electron antineutrinos, which interact with free protons. Argon, in contrast, has unique sensitivity to electron neutrinos. A large underground liquid-argon detector like ELBNF would enable us to clearly record the birth of the neutron star and will bring new understanding of neutrino flavor transformation."
