Although cosmic rays were discovered 100 years ago, their origin remains one of the most enduring mysteries in physics. Now, the IceCube Neutrino Observatory, a massive detector in Antarctica, is honing in on how the highest energy cosmic rays are produced.
An international particle physics collaboration today (Thursday, March 8) announced its first results toward answering a longstanding question - how the elusive particles called neutrinos can appear to vanish as they travel through space.
After just three months of operation, the Daya Bay Reactor Neutrino Experiment has far surpassed expectations, recording tens of thousands of particle interactions and paving the way to a better understanding of neutrinos and why the universe is built of matter rather than antimatter.

Nacre -- or mother of pearl, scientists and artisans know, is one of nature's amazing utilitarian materials.
With the exterior doors temporarily removed from Sterling Hall, workers move a three-meter diameter, hollow aluminum sphere, an essential component of the Madison Plasma…
Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, University of Wisconsin–Madison engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that could lead to improvements in high-resolution 3-D imaging, signal processing, communications, energy harvesting, sensing, and actuators for nanopositioning devices, among others.
Eleven distinguished faculty members have received named professorships, some of the highest honors for established faculty.
Deep under a hillside near Hong Kong, a pair of new antineutrino detectors are warming up for some serious physics.
At the heart of most celestial objects is a dynamo. The Earth's dynamo, spun to life in the molten metal core of our planet, generates a magnetic field that helps us find north and, perhaps more critically, shields us from solar winds that would otherwise singe our planet.

To survive in a tumultuous environment, sea urchins literally eat through stone, using their teeth to carve out nooks where the spiny creatures hide from predators and protect themselves from the crashing surf on the rocky shores and tide pools where they live.
Culminating a decade of planning, innovation and testing, construction of the world's largest neutrino observatory was successfully completed today.
It is the start of the final Antarctic drilling season for IceCube, and as researchers descend on the South Pole, there is additional reason for celebration. The National Science Foundation has signed a five-year, $34.5-million agreement with the University of Wisconsin–Madison to operate the unique IceCube telescope - a cubic kilometer in volume - buried in the Antarctic ice sheet between 1,400 meters and 2,400 meters deep.
A pair of young fusion researchers will be working with the support of the Department of Energy as they work on graduate degrees at the University of Wisconsin–Madison.
Though still under construction, the IceCube Neutrino Observatory at the South Pole is already delivering scientific results - including an early finding about a phenomenon the telescope was not even designed to study.
Daniel Lecoanet, who will graduate with comprehensive honors from University of Wisconsin–Madison this spring with a double major in math and physics, has won a five-year, no-strings-attached fellowship to pursue graduate studies.
Energy is building at the Large Hadron Collider outside of Geneva, Switzerland, in more ways than one.
