The experiments were carried out on endofullerenes, molecules of C60 into which smaller molecules of Hydrogen (H2) had been inserted. The results, published in Physical Review Letters, represent the first known example of a quantum selection rule found in a molecule.
Similar techniques were also used by the same team to uncover an exciting new symmetry-breaking interaction of water molecules with C60 cages, published last month in Physical Chemistry Chemical Physics.
Observing the quantum behavior of light is a big part of Alan Migdall's research at the Joint Quantum Institute. Many of his experiments depend on observing light in the form of photons---the particle complement of light waves---and sometimes only one photon at a time, using "smart" detectors that can count the number of individual photons in a pulse. Furthermore, to observe quantum effects, it is normally necessary to use a beam of coherent light, light for which knowing the phase or intensity for one part of the beam allows you to know things about distant parts of the same beam.
WEST LAFAYETTE, Ind. – An emerging class of electrically conductive plastics called "radical polymers" may bring low-cost, transparent solar cells, flexible and lightweight batteries and ultrathin antistatic coatings for consumer electronics and aircraft.
Researchers have established the solid-state electrical properties of one such polymer, called PTMA, which is about 10 times more electrically conductive than common semiconducting polymers.
The largest migration on the planet is the movement of small animals from the surface of the open ocean, where they feed on plants under cover of darkness, to the sunless depths where they hide from predators during the day.
An international research team comprised of German, Israeli and American ecologists, including Dr. Claus Holzapfel, Dept. of Biological Sciences, Rutgers University-Newark, has conducted unique long-term experiments in Israel to test predictions of climate change, and has concluded that plant communities in the Holy Land can cope with climate change of "biblical" dimensions.
COLUMBIA, Mo. – As more people in the middle of their careers decide to return to school to further their education, the number of students applying to graduate school programs across the country has reached a record high in the past decade. With record numbers of potential students applying to their programs, many graduate school admissions evaluators are working to develop stronger admissions criteria that assure they are admitting students who will succeed academically.
Last spring, the Colorado River reached its delta for the first time in 16 years, flowing into Pacific Ocean at the Gulf of California after wetting 70 miles of long-dry channels through the Sonoran Desert.
The discovery of a new particle will "transform our understanding" of the fundamental force of nature that binds the nuclei of atoms, researchers argue.
Led by scientists from the University of Warwick, the discovery of the new particle will help provide greater understanding of the strong interaction, the fundamental force of nature found within the protons of an atom's nucleus.
Named Ds3*(2860)ˉ, the particle, a new type of meson, was discovered by analysing data collected with the LHCb detector at CERN's Large Hadron Collider (LHC) .
NOAA's GOES-East satellite has captured visible and infrared images of Hurricane Simon since birth, and a new animation of the data created by NASA shows Simon's landfall in Mexico and movement into the U.S. Southwest. The remnants are expected to move into the U.S. central Plains and Midwest on Oct. 9 and 10.
Mazhar Ali, a fifth-year graduate student in the laboratory of Bob Cava, the Russell Wellman Moore Professor of Chemistry at Princeton University, has spent his academic career discovering new superconductors, materials coveted for their ability to let electrons flow without resistance. While testing his latest candidate, the semimetal tungsten ditelluride (WTe2), he noticed a peculiar result.
Only recently, the UN Climate Summit came together in New York to further address the necessary measures to protect the Earth from a dramatic climate change. It has long been recognised that an increase of the average temperature will cause rising oceans and thus flooded landscapes. Particularly, regions close to the coasts are endangered. While it is well known that climate change has increased average temperatures, it is less clear how temperature variability has altered with climate change.
Last spring, the Colorado River reached its delta for the first time in 16 years, flowing into Pacific Ocean at the Gulf of California after wetting 70 miles of long-dry channels through the Sonoran Desert.
CORVALLIS, Ore. – A study of the removal of two dams in Oregon suggests that rivers can return surprisingly fast to a condition close to their natural state, both physically and biologically, and that the biological recovery might outpace the physical recovery.
New research has illuminated the movement and complete structure of the spikes on HIV that the virus uses to bind to the cells it infects. This research, led by scientists at the National Institutes of Health, Weill Cornell Medical College and Yale University School of Medicine, could help advance efforts to develop HIV vaccines and treatments.
As the effects of a changing climate become acute, organizations charged with overseeing refuge areas must take action to adapt. The US Fish and Wildlife Service (USFWS) maintains the National Wildlife Refuge System, which constitutes world's largest system of protected lands and waters. According to a November BioScience article by Robert Fischman and Vicky Meretsky of Indiana University and their coauthors, the service may not always be adequately planning for an altered future, but best practices from several plans point the way for improvement.
