Philosopher Writes on the Structure of a Quantum World

Philosopher Jill North ponders what quantum mechanics has done to reality. In a post-Einstein world where wave/particles apparently exist in multidimensions, why do we seem to live in a space of only three dimensions?

Engineered Diamond Samples May Help Realize Quantum Computing Architectures

From brain to heart to stomach, the bodies of humans and animals generate weak magnetic fields that a supersensitive detector could use to pinpoint illnesses, trace drugs – and maybe even read minds. Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes.

Rocky Debris Disc Discovered Around White Dwarf Stars

The stars, known as white dwarfs — small, dim remnants of stars once like the Sun — reside 150 light-years away in the Hyades star cluster, in the constellation of Taurus (The Bull). The cluster is relatively young, at only 625 million years old.

Supernova Iron Found in Bacteria Microfossils

Most of the chemical elements have their origin in core collapse supernovae. When a star ends its life in a gigantic starburst, it throws most of its mass into space. The radioactive iron isotope Fe-60 is produced almost exclusively in such supernovae.

Massive Muon g-2 Storage Ring to be Transported from New York to Illinois

Scientists from 26 institutions around the world are planning a new experiment that could open the doors to new realms of particle physics. But first, they have to bring the core of this experiment, a complex electromagnet that spans 50 feet in diameter, from the U.S. Department of Energy's Brookhaven National Laboratory in New York to the DOE's Fermi National Accelerator Laboratory in Illinois.

Pear Shaped Nuclei in Exotic Atoms may be Linked to New Fundamental Force in Nature

An international team of physicists has found the first direct evidence of pear shaped nuclei in exotic atoms. The findings could advance the search for a new fundamental force in nature that could explain why the Big Bang created more matter than antimatter---a pivotal imbalance in the history of everything.

Connected Universe Theory Sheds New Light on Gravity

A groundbreaking paper published last week sheds new light on the theory of gravity and the potential to significantly impact global issues facing the human race, including alternative energy sources.

Fundamental Finding May Help Advance Development of Spintronics

From powerful computers to super-sensitive medical and environmental detectors that are faster, smaller and use less energy — yes, we want them, but how do we get them?

Penn Professors Receive Grant to Study Particle Physics and Gravitational Theories

Two University of Pennsylvania professors have won the chance to pursue their research full-time this fall. The Simons Foundation has awarded fellowships to Mirjam Cvetic of the Department of Physics and Astronomy and Ron Donagi of the Department of Mathematics, both in the School of Arts and Sciences. They will receive funded year-long sabbaticals from classroom teaching and academic administration.
