New light on the 'split peak' of alcohols

WASHINGTON D.C., October 14, 2014 -- For scientists probing the electronic structure of materials using a relatively new technique called resonant inelastic soft X-ray scattering (RIXS) in the last few years, a persistent question has been how to account for "split peak" spectra seen in some hydrogen-bonded materials.

New discovery will enhance yield and quality of cereal and bioenergy crops

ST. LOUIS, MO – October 13, 2014 –A team of scientists led by Thomas Brutnell, Ph.D., director of the Enterprise Rent-A-Car Institute for Renewable Fuels at the Donald Danforth Plant Science Center have developed a new way of identifying genes that are important for photosynthesis in maize, and in rice. Their research helps to prioritize candidate genes that can be used for crop improvement and revealed new pathways and information about how plants fix carbon.

Jobs plentiful for college grads

EAST LANSING, Mich. — The job market for new college graduates is red hot.

After several years of modest growth, hiring is expected to jump a whopping 16 percent for newly minted degree-holders in 2014-15, according to key findings from Recruiting Trends. The annual survey, by Michigan State University economist Phil Gardner, is the nation's largest with nearly 5,700 companies responding.

ORNL researchers make first observation of atoms moving inside bulk material

OAK RIDGE, Tenn., Oct. 13, 2014 -- Researchers at the Department of Energy's Oak Ridge National Laboratory have obtained the first direct observations of atomic diffusion inside a bulk material. The research, which could be used to give unprecedented insight into the lifespan and properties of new materials, is published in the journal Physical Review Letters (06 October 2014, DOI: 10.1103/PhysRevLett.113.155501).

Satellite sees cold front headed to absorb Bermuda's Tropical Storm Fay

At 8 a.m. EDT on Saturday, October 11, 2014, the center of tropical storm fay was located near latitude 27.1 north and longitude 65.2 west. The storm was moving toward the north near 12 mph. Maximum sustained winds were near 60 mph.

Twenty four hours later on Sunday, Oct. 12, Fay's maximum sustained winds were near hurricane-strength at 70 mph (110 kph), although little change in strength is forecast during the next 24 Hours. Fay is expected to become a post-tropical cyclone at night (on Oct. 12).

Lose the weight, not the potatoes

Ninety overweight men and women were randomly assigned to one of three groups: (1) reduced calorie/high GI, (2) reduced calorie/low GI, (3) control group with no calorie or GI restrictions. All three groups were provided potatoes, healthful recipes and instructions to consume 5-7 servings of potatoes per week. At the end of the 12-week study period, the researchers found that all three groups had lost weight and there was no significant difference in weight loss between the groups.

Some sections of the San Andreas Fault system in San Francisco Bay Area are locked, overdue

SAN FRANCISCO – Four urban sections of the San Andreas Fault system in Northern California have stored enough energy to produce major earthquakes, according to a new study that measures fault creep. Three fault sections – Hayward, Rodgers Creek and Green Valley – are nearing or past their average recurrence interval, according to the study published in the Bulletin of the Seismological Society of America (BSSA).

Icebergs once drifted to Florida, new climate model suggests

AMHERST, Mass. – Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21,000 year ago, oceanographer Alan Condron of the University of Massachusetts Amherst has shown that icebergs and meltwater from the North American ice sheet would have regularly reached South Carolina and even southern Florida. The models are supported by the discovery of iceberg scour marks on the sea floor along the entire continental shelf.

Revving up fluorescence for superfast LEDs

DURHAM, N.C. -- Duke University researchers have made fluorescent molecules emit photons of light 1,000 times faster than normal -- setting a speed record and making an important step toward realizing superfast light emitting diodes (LEDs) and quantum cryptography.

Solid nanoparticles can deform like a liquid

CAMBRIDGE, Mass--A surprising phenomenon has been found in metal nanoparticles: They appear, from the outside, to be liquid droplets, wobbling and readily changing shape, while their interiors retain a perfectly stable crystal configuration.

The research team behind the finding, led by MIT professor Ju Li, says the work could have important implications for the design of components in nanotechnology, such as metal contacts for molecular electronic circuits.

Australian teams set new records for silicon quantum computing

Two research teams working in the same laboratories at UNSW Australia have found distinct solutions to a critical challenge that has held back the realisation of super powerful quantum computers.

The teams created two types of quantum bits, or "qubits" – the building blocks for quantum computers – that each process quantum data with an accuracy above 99%. The two findings have been published simultaneously today in the journal Nature Nanotechnology.

Climate change alters ecological impacts of seasons

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.

Rare 'baby rattle' molecules reveal new quantum properties of H2O and H2

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.

Getting sharp images from dull detectors

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.
