UD team says it’s time for a reboot
Science is poised to take a “quantum leap” as more mysteries of how atoms behave and interact with each other are unlocked. (more…)
Prof. Young-Kee Kim leads conference for aspiring female scientists
On a mid-January Friday night, Savannah Thais stood at the podium in International House’s Assembly Hall and shared some of her experiences as a female student in physics. She described the refusal of some male students to work with her, the difficulty in finding a female professor or mentor in math or physics, and the common message from adults that “I can’t be ‘girly’ and good at physics.” (more…)
New discovery is rooted in physics and the arts
In creating an entirely new way to compress data, a team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has drawn inspiration from physics and the arts. The result is a new data compression method that outperforms existing techniques, such as JPEG for images, and that could eventually be adopted for medical, scientific and video streaming applications.
In data communication, scientific research and medicine, an increasing number of today’s applications require the capture and analysis of massive amounts of data in real time. (more…)
ANN ARBOR — In events that could exacerbate sea level rise over the coming decades, stretches of ice on the coasts of Antarctica and Greenland are at risk of rapidly cracking apart and falling into the ocean, according to new iceberg calving simulations from the University of Michigan.
“If this starts to happen and we’re right, we might be closer to the higher end of sea level rise estimates for the next 100 years,” said Jeremy Bassis, assistant professor of atmospheric, oceanic and space sciences at the U-M College of Engineering, and first author of a paper on the new model published in the current issue of Nature Geoscience.

From a physics Ph.D. student-turned-app builder to chimps launching an indie game studio, app builders across the globe are bringing amazing experiences to Windows 8 and enjoying success along the way.
REDMOND, Wash. – Feb. 26, 2013 – This week, thousands have descended upon Barcelona, Spain, for Mobile World Congress, the world’s premier mobile industry event. In honor of this international gathering, we’re celebrating Windows Store apps from around the world, along with stories of the people working behind the scenes to bring those apps to life on Windows 8.

The long-sought Higgs boson—the particle that endows all elementary particles in the universe with mass—was elusive no longer when scientists at the CERN physics laboratory in Switzerland, discovered it last summer.
The July 4, 2012 announcement of the discovery appealed to both the general public and the media: Fifty-five media organizations and more than one billion television viewers made it an event that couldn’t be missed. Time even dubbed the Higgs boson “Particle of the Year.” (more…)
University of Missouri’s Sergei Kopeikin may have solved the Pioneer anomaly
COLUMBIA, Mo. – Former President Bill Clinton recently expressed his support for interstellar travel at the 100 Year Spaceship Symposium, an international event advocating for human expansion into other star systems. Interstellar travel will depend upon extremely precise measurements of every factor involved in the mission. The knowledge of those factors may be improved by the solution a University of Missouri researcher found to a puzzle that has stumped astrophysicists for decades.
“The Pioneer spacecraft, two probes launched into space in the early 70s, seemed to violate the Newtonian law of gravity by decelerating anomalously as they traveled, but there was nothing in physics to explain why this happened,” said Sergei Kopeikin, professor of physics and astronomy in MU’s College of Arts and Science. “My study suggests that this so-called Pioneer anomaly was not anything strange. The confusion can be explained by the effect of the expansion of the universe on the movement of photons that make up light and radio waves.” (more…)
Berkeley Lab Researchers Propose a Way to Build the First Space-Time Crystal
Imagine a clock that will keep perfect time forever, even after the heat-death of the universe. This is the “wow” factor behind a device known as a “space-time crystal,” a four-dimensional crystal that has periodic structure in time as well as space. However, there are also practical and important scientific reasons for constructing a space-time crystal. With such a 4D crystal, scientists would have a new and more effective means by which to study how complex physical properties and behaviors emerge from the collective interactions of large numbers of individual particles, the so-called many-body problem of physics. A space-time crystal could also be used to study phenomena in the quantum world, such as entanglement, in which an action on one particle impacts another particle even if the two particles are separated by vast distances.
A space-time crystal, however, has only existed as a concept in the minds of theoretical scientists with no serious idea as to how to actually build one – until now. An international team of scientists led by researchers with the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) has proposed the experimental design of a space-time crystal based on an electric-field ion trap and the Coulomb repulsion of particles that carry the same electrical charge.
