Contrary to some previous, highly publicized, reports, ocean acidification is not likely to worsen the hearing of whales and other animals, according to a Woods Hole Oceanographic Institution (WHOI) scientist who studies sound propagation in the ocean.

Scientists at the University of Leicester are using an unusual resource to investigate ancient climates– prehistoric animal urine.
The fragrances used in many household and skincare products can cause contact allergy when exposed to oxygen in the air, reveals research from the University of Gothenburg's Faculty of Science in conjunction with the University of Gothenburg to be presented at the dermatologist conference in Gothenburg.
BOULDER--Changes in population growth and composition, including aging and urbanization, could significantly affect global emissions of carbon dioxide over the next 40 years, according to a new study out next week.
Geologists studying the Jan. 12 Haiti earthquake say the risk of destructive tsunamis is higher than expected in places such as Kingston, Istanbul, and Los Angeles.
Like Haiti's capital, these cities all lie near the coast and near an active geologic feature called a strike-slip fault where two tectonic plates slide past each other like two hands rubbing against each other.
RICHMOND, Va. (Oct. 8, 2010) – An international team of researchers has discovered a new class of highly electronegative chemical species called hyperhalogens, which use superhalogens as building blocks around a metal atom. The new chemical species may have application in many industries.
RUSTON, La. – Dr. Long Que, assistant professor of electrical engineering at Louisiana Tech University, has reported success in designing and fabricating a device that allows microscale electronic devices to harvest their own wasted energy.
The work was described in a paper published in the September edition of Applied Physics Letters and has also caught the attention of PhysOrg.com, a website that features breakthroughs in science and technology from all over the world.
Researchers believe that the puzzle of catalytic gold is now partially solved. Gold can catalyse an oxidation reaction by first oxidising itself. New research evidence on gold-oxide phase at room temperature and atmospheric pressure help us to finally understand the oxidation mechanisms of catalytic gold nanoclusters in these conditions.
Cambridge, Mass., October 7, 2010 – A collaborative, six-year study of carbon dioxide (CO2) levels in Beijing and surrounding provinces suggests that combustion efficiency, a component of overall energy efficiency, is improving in the region.
The findings, published in the September 21 issue of Atmospheric Chemistry and Physics, are generally consistent with official Chinese government statistics and could bolster their credibility as international negotiations proceed on commitments of China and other nations to combat climate change.
The "turtle and dugong capital of the world", the northern Great Barrier Reef (GBR) and Torres Strait region, faces increased pressure under climate change from human actions such as fishing, hunting, onshore development and pollution.
"Depletion of turtle and dugong numbers increases their vulnerability to other threats and lowers their ability to cope with climate change," Dr Mariana Fuentes of the ARC Centre of Excellence for Coral Reef Studies and James Cook University will tell the Coral Reef Symposium in Canberra today.
CHAMPAIGN, Ill. — University of Illinois chemistry professor Alexander Scheeline wants to see high school students using their cell phones in class. Not for texting or surfing the Web, but as an analytical chemistry instrument.
An approach pioneered by researchers at North Carolina State University gives scientists new insight into the way silicon bonds with other materials at the atomic level. This technique could lead to improved understanding of and control over bond formation at the atomic level, and opportunities for the creation of new devices and more efficient microchips.
