A novel type of inter-particle binding predicted in 1970 and observed for the first time in 2006, is forming the basis for an intriguing kind of ultracold quantum chemistry. Chilled to nano-kelvin temperatures, cesium atoms---three at a time---come together to form a bound state hundreds or even thousands of times larger than individual atoms.

A year ago Northwestern University chemists published their recipe for a new class of nanostructures made of sugar, salt and alcohol. Now, the same team has discovered the edible compounds can efficiently detect, capture and store carbon dioxide. And the compounds themselves are carbon-neutral.
TORONTO, ON - Clean solutions to human energy demands are essential to our future. While sunlight is the most abundant source of energy at our disposal, we have yet to learn how to capture, transfer and store solar energy efficiently. According to University of Toronto chemistry professor Greg Scholes, the answers can be found in the complex systems at work in nature.
Spanish researchers have designed what they believe to be a new type of magnetic cloak, which shields objects from external magnetic fields, while at the same time preventing any magnetic internal fields from leaking outside, making the cloak undetectable.
The development of such a device, described as an 'antimagnet', could offer many beneficial applications, such as protecting a ship's hull from mines designed to detonate when a magnetic field is detected, or allowing patients with pacemakers or cochlear implants to use medical equipment.
An international team of researchers will begin gathering in the Indian Ocean next month, using aircraft, ships, moorings, radars, numerical models and other tools to study how tropical weather brews there and moves eastward along the equator, with reverberating effects around the globe.
The six-month field campaign, known as DYNAMO or Dynamics of the Madden-Julian Oscillation, will help improve long-range weather forecasts and seasonal outlooks and enable scientists to further refine computer models of global climate.
Changes in the ratio of nitrate to phosphorus in the oceans off the coasts of Korea and Japan caused by atmospheric and riverine pollutants may influence the makeup of marine plants and influence marine ecology, according to researchers from Korea and the U. S.
Why does a solid metal that is engineered for ductility become brittle, often suddenly and with dramatic consequences, in the presence of certain liquid metal impurities?
The phenomenon, known as liquid metal embrittlement, or LME, has baffled metallurgists for a century.
Now, a team of ceramics researchers has shed light on LME by obtaining atomic-scale images of unprecedented resolution of the grain boundaries, or internal interfaces, where LME occurs.
A study published by researchers at the RIKEN Advanced Science Institute (ASI) has shed first-ever light on a class of heterometallic molecular structures whose unique features point the way to breakthroughs in the development of lightweight fuel cell technology. The structures contain a previously-unexplored combination of rare-earth and d-transition metals ideally suited to the compact storage of hydrogen.
WASHINGTON -- Stereotypes suggest women are more cooperative than men, but an analysis of 50 years of research shows that men are equally cooperative, particularly in situations involving a dilemma that pits the interests of an individual against the interests of a group.
Additionally, men cooperate better with other men than women cooperate with each other, according to the research, published online by the American Psychological Association in Psychological Bulletin. Women tend to cooperate more than men when interacting with the opposite-sex, the analysis found.
After the magnitude 9.0 earthquake and resulting tsunami in Japan on March 11, 2011, the Fukushima Dai-ichi power plant was severely compromised and radioactive material was found in the water in many of the surrounding areas, but the extent of this contamination remained unknown. In a study published today in the online journal PLoS ONE, researchers report that the reactor accident fallout extended as far as the San Francisco Bay area, resulting in elevated levels of radioactive material that were nonetheless very low and posed no health risk to the public.
Global emissions of carbon dioxide (CO2) – the main cause of global warming – increased by 45 % between 1990 and 2010, and reached an all-time high of 33 billion tonnes in 2010. Increased energy efficiency, nuclear energy and the growing contribution of renewable energy are not compensating for the globally increasing demand for power and transport, which is strongest in developing countries.
The Universe wouldn't be the same without the Higgs boson. This legendary particle plays a role in cosmology and reveals the possible existence of another closely related particle.
EUGENE, Ore. -- (Sept. 21, 2011) -- University of Oregon researchers have devised a mathematically rich analytic approach to account for often-missing thermodynamic and molecular parameters in molecular dynamic simulations.
NEW BRUNSWICK, N.J.: – A new plant that buries its seeds, the first in its family, is discovered in the Atlantic forest of Bahia, Brazil, by an international team of scientists.
A University of Alberta research team has turned their newly developed 3-D microscope technology on ancient sea creatures and hopes to expand its use.
