Berkeley Lab Climate Scientists See Better Climate Models, Warmer Future

Berkeley Lab experts contribute to IPCC 5th Assessment Report.

Over the next century, most of the continents are on track to become considerably warmer, with more hot extremes and fewer cold extremes. Precipitation will increase in some parts of the world but will decrease in other parts. These are some of the conclusions reached by Lawrence Berkeley National Laboratory (Berkeley Lab) scientist Michael Wehner and his co-authors on the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC).

Wehner, a climate scientist in Berkeley Lab’s Computational Research Division, and William Collins, head of the Lab’s Climate Sciences Department, were lead authors on the IPCC report’s chapters on long-term climate change projections and climate models, respectively. They are among more than 200 lead authors from more than 30 countries in IPCC’s Working Group I. Their report released today provides a comprehensive assessment of the physical science basis of climate change. (more…)

Gentechnikfreies Raps-Saatgut ist möglich

Greenpeace und Bioland fordern: Nulltoleranz muss bleiben

Deutsches Rapssaatgut ist frei von Gentechnik. Das geht aus den von Greenpeace und Bioland abgefragten Saatgutanalysen der Bundesländer hervor. Die zuständigen Behörden hatten 281 Rapssaatgut-Proben getestet. Verunreinigungen haben sie nicht festgestellt. Im vergangenen Jahr waren noch fünf von 337 Rapssaatgut-Proben positiv getestet worden.

“Staatliche Kontrollen sind wichtig. Die diesjährige Analyse zeigt, dass sauberes Saatgut möglich ist”, sagt Jan Plagge, Präsident von Bioland. “Die Nulltoleranz für Saatgut muss auch zukünftig bestehen bleiben”, fordert Plagge. Immer wieder wird auf EU-Ebene eine Aufweichung der Nulltoleranz ins Gespräch gebracht. Auch dieses Jahr forderte der Bundesverband Deutscher Pflanzenzüchter BDP, Schwellenwerte für gentechnische Verunreinigung von Saatgut einzuführen. (more…)

Simulation success

Engineering doctoral students win Composites Simulation Challenge

Two University of Delaware mechanical engineering doctoral students working in the Center for Composite Materials, Subramani Sockalingam and Raja Ganesh, took first prize at the American Society for Composites (ASC) inaugural Student Simulation Challenge held Sept. 9 at Pennsylvania State University.

The goal of the 12-hour competition, held during the annual ASC Technical Conference, was to see which student team could best predict the behavior of a composite laminate material that included a pattern of holes. (more…)

Science Benefits From Diverse Landing Area of NASA Mars Rover

PASADENA, Calif. — NASA’s Curiosity rover is revealing a great deal about Mars, from long-ago processes in its interior to the current interaction between the Martian surface and atmosphere.

Examination of loose rocks, sand and dust has provided new understanding of the local and global processes on Mars. Analysis of observations and measurements by the rover’s science instruments during the first four months after the August 2012 landing are detailed in five reports in the Sept. 27 edition of the journal Science.

MU Scientist Finds Late Cretaceous Period Was Likely Ice-free

Study results could foreshadow earth’s future climate, MU researcher says

COLUMBIA, Mo. – For years, scientists have thought that a continental ice sheet formed during the Late Cretaceous Period more than 90 million years ago when the climate was much warmer than it is today. Now, a University of Missouri researcher has found evidence suggesting that no ice sheet formed at this time. This finding could help environmentalists and scientists predict what the earth’s climate will be as carbon dioxide levels continue to rise.

“Currently, carbon dioxide levels are just above 400 parts per million (ppm), up approximately 120 ppm in the last 150 years and rising about 2 ppm each year,” said Ken MacLeod, a professor of geological sciences at MU. “In our study, we found that during the Late Cretaceous Period, when carbon dioxide levels were around 1,000 ppm, there were no continental ice sheets on earth. So, if carbon dioxide levels continue to rise, the earth will be ice-free once the climate comes into balance with the higher levels.” (more…)

Weltweit Wilderei-Exzesse stoppen

WWF fordert Sofortaktion der UNO gegen Wildereikrise

Mehr als geschätzt 19 Milliarden US-Dollar jährlich werden weltweit mit illegalen Wildtierprodukten umgesetzt. Derzeit stehen vor allem afrikanische Elefanten und Nashörner im Fadenkreuz der Wilderer. Dabei ist der illegale Artenhandel längst zur Bedrohung von Frieden und Sicherheit der betroffenen Staaten geworden. Mit welchen Maßnahmen die internationale Gemeinschaft die Wilderei bekämpfen kann, wird auf Einladung von Gabuns Präsident Ali Bongo Ondimba und Deutschlands Außenminister Guido Westerwelle am Donnerstag während der 68. Generalversammlung der Vereinten Nationen in New York mit  Staatspräsidenten und hochrangigen Entscheidungsträgern zahlreicher Staaten diskutiert. Ziel der UNO müsse sein, das Problem so ernst zu nehmen wie den Handel mit Drogen, Waffen und Menschen, fordert der WWF. (more…)

Initial positive results reported on vaccine to treat genital herpes

Initial, positive results have been reported for a therapeutic vaccine candidate for treating patients with genital herpes. This first-in-class, investigational, protein subunit vaccine, GEN-003, is under development by Genocea Biosciences Inc.

Dr. Anna Wald, University of Washington professor of medicine and laboratory medicine in the School of Medicine and professor of epidemiology in the School of Public Health, is among those leading clinical studies of GEN-003. The trials are also taking place at six other centers in the United States. (more…)

Mobile computing in the ‘bring your own device’ era

Early in September Yale passed a milestone in mobile computing, with a record 39,414 mobile devices connected to its wireless networks. As on most college campuses the growth of mobile computing at Yale has been explosive, from well under 10,000 devices three years ago to almost 40,000 today.

A recent Gartner study showed that smartphone ownership among college students went from 55% in 2011 to 62% in 2012, and the percentage of students using their smartphones for academic work doubled in the same period. The typical U.S. college student now routinely uses between 2-3 wireless devices, and higher education computing experts predict that average to grow to 3-4 devices over the next year. (more…)
