Experimental Protocol Proposed for Demonstrating Quantum Entanglement at the Macroscopic Scale

Quantum entanglement refers to the "pairing" of two subatomic particles in such a way that they form a whole quantum system. Interest in entanglement is increasing today, as it challenges the foundations of quantum mechanics itself, and is also key for achieving quantum information processing and communication.

Mysterious Effect in Superfluids Linked to Whirlpool-Like Structures

So long, solitons: University of Chicago physicists have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence of solitons—exotic, solitary waves.

CERN Celebrates 60 Years of International Collaboration

Today, CERN, the European Organization for Nuclear Research, is blowing out 60 candles at an event attended by official delegations from 35 countries. Founded in 1954, CERN is today the largest particle physics laboratory in the world and a prime example of international collaboration, bringing together scientists of almost 100 nationalities.

Primordial Stars May Have Died Unusually

Certain primordial stars—those 55,000 and 56,000 times the mass of our Sun, or solar masses—may have died unusually. In death, these objects—among the Universe's first-generation of stars—would have exploded as supernovae and burned completely, leaving no remnant black hole behind.

AMS Detector on ISS Measures Sum Flux of Cosmic Rays Electrons and Positrons

Latest results of the measurement of high-energy particles with the AMS detector on the international space station ISS provide for a deeper understanding of the origin and nature of cosmic rays. A young investigator group of Karlsruhe Institute of Technology (KIT), which is headed by Dr. Iris Gebauer, is involved in this experiment. It measured the sum flux of cosmic rays electrons and positrons. The spokesperson of the AMS project, Professor Samuel C. C. Ting, presented the results at the CERN Research Center last week.

Fusion of Electricity and Magnetism in a Single Material Paves Way for Advanced Computing Architectures

Electricity and magnetism rule our digital world. Semiconductors process electrical information, while magnetic materials enable long-term data storage. A University of Pittsburgh research team has discovered a way to fuse these two distinct properties in a single material, paving the way for new ultrahigh density storage and computing architectures.

Magnets Steer Particles at Swiss Light Source Accelerator Facility

Magnets are the unsung heroes in particle accelerators because they keep protons or electrons on track. But such magnets have very little in common with the small ones on the domestic fridge door. Quite a few of the magnets at PSI are heavier and bulkier than the fridge itself, yet despite this they are also masterpieces of precision and control.

Galaxy DDO 68 May Not be as Young as it Looks

Astronomers usually have to peer very far into the distance to see back in time, and view the Universe as it was when it was young. This new NASA/ESA Hubble Space Telescope image of galaxy DDO 68, otherwise known as UGC 5340, was thought to offer an exception. This ragged collection of stars and gas clouds looks at first glance like a recently-formed galaxy in our own cosmic neighbourhood. But, is it really as young as it looks?

Information Stored in Quantum Bits Exponentially Compressed Without Losing Information

CIFAR researchers have shown that information stored in quantum bits can be exponentially compressed without losing information. The achievement is an important proof of principle, and could be useful for efficient quantum communications and information storage.
