Students from OSU's Radiation Physics Laboratory built and successfully launched a cosmic radiation detector this summer that reached the edge of outer space. Carried by a helium-filled balloon 12 inches in diameter, the detector flew for more than two hours and reached 104,000 feet in altitude. The device recorded radiation levels at the varying altitudes – information that will be used by NASA to develop instrumentation for space flight.
Ruins of a Roman temple from the second century CE have recently been unearthed in the Zippori National Park in Israel. Above the temple are foundations of a church from the Byzantine period. The excavations, which were undertaken by the Noam Shudofsky Zippori Expedition led by of Prof. Zeev Weiss of the Institute of Archaeology at the Hebrew University of Jerusalem, shed light on the multi-cultural society of ancient Zippori.
The Carbon Disclosure Project (CDP) and ICLEI-Local Governments forSustainability are joining forces with some of the United States' largestcities to help them voluntarily report their greenhouse gas emissions andother climate change-relevant data.
Hundreds of insect species live mainly underwater, but how do they breathe? University of Alberta researcher Morris Flynn did a study to find out how these species are able to remain underwater without drowning.
Trying to appear moderate is not always the best strategy for capturing votes during an election, reveals a new study. Extreme positions can build trust among an electorate, who value ideological commitment in times of uncertainty.
"The current political advantage of the Republican Party stems from the ability of its candidates to develop 'signature ideas.' This strategy is rewarded even when the electorate has ideological reservations," says University of Southern California economist Juan Carrillo, adding that this poses a challenge for the Democrats.
Virginia Key, Fla. – Climate models have long predicted that global warming will increase the intensity of extreme precipitation events. A new study conducted at the University of Miami and the University of Reading (U.K.) provides the first observational evidence to confirm the link between a warmer climate and more powerful rainstorms.
Volunteers who take part in conservation efforts may do it more for themselves than the wildlife they are trying to protect, a University of Alberta case study shows.
A study of purple martin landlords—those who keep and monitor special birdhouses on their land—revealed that they were more motivated to take part in the conservation project for egoistic rather than altruistic reasons.
B cells, the source of damaging autoantibodies, have long been thought to depend upon T cells for their activation and were not considered important in the initiation of autoimmune diseases like lupus or rheumatoid arthritis.
In the Aug. 7 online issue of the journal of Immunity, Yale University researchers turn this paradigm on its head by showing that in systemic autoimmune diseases B cells can be activated the absence of T cells.
The study suggests new ways to intervene in the immune system's chronic attacks on the body's own tissue.
Geneva, 7 August 2008. CERN has today announced that the first attempt to circulate a beam in the Large Hadron Collider (LHC) will be made on 10 September. This news comes as the cool down phase of commissioning CERN's new particle accelerator reaches a successful conclusion. Television coverage of the start-up will be made available through Eurovision.
Approximately 15 professors, deans and other professionals in the computing sciences from the People's Republic of China came to Arlington, Va. last month for a summit with their U.S. counterparts. The one-day meeting gave participants the chance to discuss challenges and opportunities facing computing scholars from both sides of the Pacific, and it reflected the growing level of cooperation between the academic research communities in both countries.
