Quantum Researchers Open Possibility of Submolecular Control of Bond-Selective Chemistry in Single Functionalized Molecule

Recently, Dr. Ying Jiang, from International Center for Quantum Materials of Peking University, and his co-workers open up the possibility of submolecular control of the bond-selective chemistry in a single functionalized molecule. This work is published in Nature Chemistry [Nature Chem. DOI: 10.1038/NCHEM.1488 (2012)], and the referee thinks highly of the work as an “experimental tour de force”.

Internet Growth Linked to Emergence of Universe’s Four-Dimensional Spacetime from Quantum Vacuum

The structure of the universe and the laws that govern its growth may be more similar than previously thought to the structure and growth of the human brain and other complex networks, such as the Internet or a social network of trust relationships between people, according to a new paper published in the science journal Nature’s Scientific Reports.

Comparing Types of Supernovae May Help Define Nature of Dark Energy

Supercomputer simulations have revealed that a type of oddly dim, exploding star is probably a class of duds—one that could nonetheless throw new light on the mysterious nature of dark energy.

Multi-Object Double Spectrograph Reveals Likely Origins of Bright Supernovae

A study using a unique new instrument on the world's largest optical telescope has revealed the likely origins of especially bright supernovae that astronomers use as easy-to-spot "mile markers" to measure the expansion and acceleration of the universe.

Study Reveals Preferred Direction of Time's Quantum Arrow

Time marches relentlessly forward for you and me; watch a movie in reverse, and you'll quickly see something is amiss. But from the point of view of a single, isolated particle, the passage of time looks the same in either direction. For instance, a movie of two particles scattering off of each other would look just as sensible in reverse – a concept known as time reversal symmetry.

Large Underground Xenon Experiment to Look for Dark Matter is Now Underwater

An experiment to look for one of nature's most elusive subatomic particles is finally underwater, in a stainless steel tank nearly a mile underground beneath the Black Hills of South Dakota. And among the dozens of scientists involved in the research collaboration is the University of Rochester's Professor Frank Wolfs.
