*Three-year series of scientific missions from Arctic to Antarctic produces new views of atmospheric chemistry*
A three-year series of research flights from the Arctic to the Antarctic has successfully produced an unprecedented portrait of greenhouse gases and particles in the atmosphere.
The far-reaching field project, known as HIPPO, ends this week, and has enabled researchers to generate the first detailed mapping of the global distribution of gases and particles that affect Earth’s climate. (more…)
*Scientists have successfully created synthetic crystals whose structures and properties mimic those of naturally-occurring biominerals such as seashells.*
*The findings, published in the journal Nature Materials, could be an important step in the development of high-performance materials, which could be manufactured under environmentally-friendly conditions.*
Professor Stephen Eichhorn, who has just moved to the University of Exeter from the University of Manchester, played a key role in the research. Professor Eichhorn has been appointed to a Chair in Functional Materials, through the University of Exeter’s £230 million investment in science, medicine and engineering. Exeter’s vision is for a multidisciplinary and interdisciplinary approach to the understanding and application of functional materials – from fundamentals to manufacture – exploiting world-leading materials knowledge to deliver new concepts, processes and products.

ANN ARBOR, Mich.— The ideal of equal housing opportunities is closer to becoming a reality in most major U.S. metro areas, according to a University of Michigan researcher.(more…)
EAST LANSING, Mich. — Researchers at Michigan State University have unraveled the mystery of how microbes generate electricity while cleaning up nuclear waste and other toxic metals.
Details of the process, which can be improved and patented, are published in the current issue of the Proceedings of the National Academy of Sciences. The implications could eventually benefit sites forever changed by nuclear contamination, said Gemma Reguera, MSU microbiologist. (more…)
Anatomically modern humans interbred with more archaic hominin forms even before they migrated out of Africa, a UA-led team of researchers has found
It is now widely accepted that anatomically modern humans of the species Homo sapiens originated in Africa and eventually spread throughout the world. Ancient DNA recovered from fossil Neanderthal bones suggests they interbred with more archaic hominin forms once they had left their evolutionary cradle for the cooler climates of Eurasia, but whether they exchanged genetic material with other, now extinct archaic hominin varieties in Africa remained unclear.(more…)
Pediatric obesity ends up costing $3 billion annually in the U.S., but a significant amount of that could be saved by streamlining medical coverage to address health issues affecting young obese patients now rather than waiting to treat conditions they develop as they get older, according UCLA researchers and colleagues.(more…)
In a detailed assessment of the Deepwater Horizon oil spill, researchers led by a team from the Woods Hole Oceanographic Institution (WHOI) have determined that the blown-out Macondo well spewed oil at a rate of about 57,000 barrels a day, totaling nearly 5 million barrels of oil released from the well between April 20 and July 15, 2010, when the leak was capped. In addition, the well released some 100 million standard cubic feet per day of natural gas. (more…)
UCL scientists are part of an international team which has developed a novel X-ray technique for imaging atomic displacements in materials with unprecedented accuracy.(more…)
