BOSTON, Aug. 24, 2010 — Continuous research and development of alternative energy could soon lead to a new era in human history in which two renewable sources — solar and wind — will become Earth's dominant contributor of energy, a Nobel laureate said here today at a special symposium at the American Chemical Society's 240th National Meeting.

BOSTON, Aug. 24, 2010 — Crafting a fragrance for detergents that leaves laundry smelling clean and fresh. Developing a room freshener, scented oil, or scented candle that whispers "cool spring air." Giving toothpaste or mouthwash a refreshing aftertaste that lingers and lingers.

The process for putting the smell that sells into thousands of consumer products is much like composing a symphony, according to maestro fragrance designer Michael Papas, who spoke here today at the 240th National Meeting of the American Chemical Society (ACS).

In the aftermath of the explosion of BP's Deepwater Horizon drilling rig in the Gulf of Mexico, a dispersed oil plume was formed at a depth between 3,600 and 4,000 feet and extending some 10 miles out from the wellhead. An intensive study by scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) found that microbial activity, spearheaded by a new and unclassified species, degrades oil much faster than anticipated. This degradation appears to take place without a significant level of oxygen depletion.

Scientists map origin of large, underwater hydrocarbon plume in Gulf

Scientists funded by the National Science Foundation (NSF) and affiliated with the Woods Hole Oceanographic Institution (WHOI) have detected a plume of hydrocarbons at least 22 miles long and more than 3,000 feet below the surface of the Gulf of Mexico, a residue of the BP Deepwater Horizon oil spill.

LAWRENCE — Using powerful lasers, Hui Zhao, assistant professor of physics and astronomy at the University of Kansas, and graduate student Lalani Werake have discovered a new way to recognize currents of spinning electrons within a semiconductor.

Their findings could lead the way to development of superior computers and electronics. Results from their work in KU's Ultrafast Laser Lab will be published in the September issue of Nature Physics, a leading peer-reviewed journal, and was posted online in early August.

COLUMBUS, Ohio – Even after leaving a violent or controlling relationship, the mental health of mothers may actually get worse before it gets better, a new study suggests.

Researchers found that in the two years after the end of an abusive relationship, mothers showed poorer mental health, became more depressed and maintained high levels of anxiety. In those areas, they were no better off than women who stayed in abusive relationships.

Laughter can play key roles in group communication and group dynamics – even when there's nothing funny going on. That's according to new research from North Carolina State University that examined the role of laughter in jury deliberations during a capital murder case.

By autumn 2009, almost half of the population of Norway had been vaccinated against the pandemic influenza A (H1N1) virus. Many had also been infected by the virus during the summer and autumn outbreaks. The majority of those who were vaccinated or were infected are expected to have developed immunity to the virus. A study of the Norwegian population's immune status to the pandemic virus in January 2010 was recently published in the journal Eurosurveillance.

In the war against infectious disease, identifying the culprit is half the battle. Now, research professor Shaopeng Wang and his colleagues from the Biodesign Institute at Arizona State University, describe a new method for visualizing individual virus particles. Their research opens the door to a more detailed understanding of these minute pathogens, and may further the study of a broad range of micro- and nanoscale phenomena.

The group's findings appear in the August 23rd Proceedings of the National Academy of Science, advanced online issue.

LIVERMORE, Calif. -- Americans are using less energy overall and making more use of renewable energy resources.

The United States used significantly less coal and petroleum in 2009 than in 2008, and significantly more wind power. There also was a decline in natural gas use and increases in solar, hydro and geothermal power according to the most recent energy flow charts released by the Lawrence Livermore National Laboratory.

Overutilization of medical imaging services exposes patients to unnecessary radiation and adds to healthcare costs, according to a report appearing online and in the October issue of the journal Radiology that calls on radiologists to spearhead a collaborative effort to curb imaging overutilization.

BOSTON, Aug. 23, 2010 — Scientists reported progress today in using a common virus to develop improved materials for high-performance, rechargeable lithium-ion batteries that could be woven into clothing to power portable electronic devices. They discussed development of the new materials for the battery's cathode, or positive electrode, at the 240th National Meeting of the American Chemical Society (ACS), being held here this week.

Scientists at the Smithsonian Institution and the Hawaii Institute of Marine Biology at the University of Hawaii at Manoa have created the first frozen bank for Hawaiian corals in an attempt to protect them from extinction and to preserve their diversity in Hawaii. Mary Hagedorn, an adjunct faculty member at HIMB and a research scientist with the Smithsonian Conservation Biology Institute, leads the laboratory at the HIMB research facilities on Coconut Island in Kaneohe Bay, Oahu, that is banking the frozen coral cells.

CHAPEL HILL – Flu vaccine will soon be available at local pharmacies and doctor's offices, and government officials are urging everyone over 6 months of age to receive it. This year's vaccine protects against H1N1 and two other strains of seasonal flu.

The recommendation represents a break from past years, when the government focused on vaccinating people in certain "high-risk" groups and those in contact with people at high risk.
