Controlling the shapes of nanometer-sized catalytic and electrocatalytic particles made from noble metals such as platinum and palladium may be more complicated than previously thought.

COLUMBUS, Ohio—When renowned explorer Richard E. Byrd returned from the first-ever flight to the North Pole in 1926, he sparked a controversy that remains today: Did he actually reach the pole?
Studying supercomputer simulations of atmospheric conditions on the day of the flight and double-checking Byrd's navigation techniques, a researcher at The Ohio State University has determined that Byrd indeed neared the Pole, but likely only flew within 80 miles of it before turning back to the Norwegian island of Spitsbergen.
COLUMBIA, Mo. – Although no exact formula for marital bliss exists, a University of Missouri researcher has found that husbands and wives are happier when they share household and child-rearing responsibilities. However, sharing responsibilities doesn't necessarily mean couples divide chores equally, said Adam Galovan, a doctoral student in the MU Department of Human Development and Family Studies.
DURHAM, N.C. -- For more than 40 years, snowmelt and runoff from Morocco's High Atlas Mountains has been dammed and redirected hundreds of kilometers to the south to irrigate oases farms in the arid, sub-Saharan Draa Basin.
But a new study by American and Moroccan scientists finds that far from alleviating water woes for the six farm oases in the basin, the inflow of imported water has exacerbated problems by dramatically increasing the natural saltiness of their groundwater.
Scientists from Cardiff University and the University of Barcelona have discovered new clues about past rapid climate change.
The research, published this month in the journal Nature Geoscience, concludes that oceanographic reorganisations and biological processes are linked to the supply of airborne dust in the Southern Ocean and this connection played a key role in past rapid fluctuations of atmospheric carbon dioxide levels, an important component in the climate system.
Shaken, not stirred, is the essence of new research that's showing promise in creating the chemical reactions necessary for industries such as pharmaceutical companies, but eliminating the resulting waste from traditional methods. James Mack, a University of Cincinnati associate professor of chemistry, will present this research into greener chemistry on April 9, at the annual meeting of the American Chemical Society in New Orleans.
NEW ORLEANS, April 8, 2013 — Top leaders in chemistry — a $760 billion annual enterprise in the United States and $3.5 trillion worldwide — are gathering here today to consider a formula for ensuring the future success of the scientists whose work touches 96 percent of all the world's manufactured goods.
NEW ORLEANS, April 8, 2013 — With global climate change and the prospect of another record-hot summer on the minds of millions of people, experts have gathered here today to encourage scientists to take a more active role in communicating the topic to the public, policy makers and others. The symposium, "Understanding Climate Science: A Scientist's Responsibility," is part of the 245th National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society.
A new study has found that pollution from fine particles in the air – mainly the result of burning coal or volcanic eruptions – can shade corals from sunlight and cool the surrounding water resulting in reduced growth rates.
NEW ORLEANS, April 7, 2013 — The American Chemical Society (ACS) today announced awarding the first grants in a new initiative intended to increase understanding of the science underpinning global climate change among thousands of people around the country.

HOUSTON -- (April 5, 2013) -- Rice University physicists on the hunt for the origins of high-temperature superconductivity have published new findings this week about a material that becomes "schizophrenic" -- simultaneously exhibiting the characteristics of both a metallic conductor and an insulator.
Osmosis – the flow of a solvent across a semipermeable membrane from a region of lower to higher solute concentration – is a well-developed concept in physics and biophysics. The problem is that, even though the concept is important to plant and human physiology, osmosis is understood in biology and chemistry in a much simpler – and often incorrect – way.
