For years, policymakers have attempted to create communities where a diverse group of residents not only live close to one other but also interact freely – in other words, neighborhoods that are both integrated and socially cohesive. (more…)
Quantum entanglement, a perplexing phenomenon of quantum mechanics that Albert Einstein once referred to as “spooky action at a distance,” could be even spookier than Einstein perceived.
Physicists at the University of Washington and Stony Brook University in New York believe the phenomenon might be intrinsically linked with wormholes, hypothetical features of space-time that in popular science fiction can provide a much-faster-than-light shortcut from one part of the universe to another.

Hee Oh joined Yale’s math department this year from Brown. Here she talks about absolute abstraction, the joy of walking — and missing math during her years as a social activist.
You received your doctorate in mathematics from Yale in 1997, then served on the faculties of Princeton, Cal Tech, and Brown, among others. What drew you back to Yale?
The math department at Yale has been well known for its strength in Lie groups, geometry, and dynamics for a long time. It was an honor and in itself a big draw for me to be asked to participate in continuing this tradition. In the end, however, I felt in my Christian faith that God was leading me this way, and I made the final decision accordingly. (more…)
Noble gas molecules have been detected in space for the first time in the Crab Nebula, a supernova remnant, by astronomers at UCL. (more…)
NASA’s Hubble Space Telescope has observed water vapor above the frigid south polar region of Jupiter’s moon Europa, providing the first strong evidence of water plumes erupting off the moon’s surface. (more…)
A massive impact on the Moon about 4 billion years ago left a 2,500-mile crater, among the largest known craters in the solar system. Smaller subsequent impacts left craters within that crater. Comparing the spectra of light reflected from the peaks of those craters may yield clues to the composition of the Moon’s lower crust and mantle — and would have implications for models of how the Moon formed.
PROVIDENCE, R.I. [Brown University] — Researchers from Brown University and the University of Hawaii have found some mineralogical surprises in the Moon’s largest impact crater. (more…)
AUSTIN, Texas — In a finding of relevance to the search for life in our solar system, researchers at The University of Texas at Austin’s Institute for Geophysics, the Georgia Institute of Technology, and the Max Planck Institute for Solar System Research have shown that the subsurface ocean on Jupiter’s moon Europa may have deep currents and circulation patterns with heat and energy transfers capable of sustaining biological life.
Scientists believe Europa is one of the planetary bodies in our solar system most likely to have conditions that could sustain life, an idea reinforced by magnetometer readings from the Galileo spacecraft detecting signs of a salty, global ocean below the moon’s icy shell. (more…)
Originally predicted in the 1920s by Satyendranath Bose and Albert Einstein, applications could include energy-efficient lasers and optical switches, critical components for future computer systems processing Big Data
ZURICH – 10 Dec 2013: For the first time, scientists at IBM Research have demonstrated a complex quantum mechanical phenomenon known as Bose-Einstein condensation (BEC), using a luminescent polymer (plastic) similar to the materials in light emitting displays used in many of today’s smartphones.
This discovery has potential applications in developing novel optoelectronic devices including energy-efficient lasers and ultra-fast optical switches — critical components for powering future computer systems to process massive Big Data workloads. The use of a polymer material and the observation of BEC at room temperature provides substantial advantages in terms of applicability and cost. (more…)
