Greg Landsberg, professor of physics at Brown, is the physics coordinator for the Compact Muon Solenoid (CMS) at CERN in Switzerland, part of a Brown team that includes professors David Cutts, Ultich Heintz, and Meenakshi Narain. The giant instrument’s primary mission is finding the Higgs boson, a particle whose existence would confirm the best guess physicists have made about why things have mass. (more…)
It’s been a decade since a swarm of relatively mild earthquakes shook up parts of Spokane. Now, armed with the right tools, scientists want to find out what was at fault.
“It was always something not as well understood as we thought it should be,” said Douglas Gibbons, a University of Washington researcher in Earth and space sciences, who is guiding installation of strong-motion sensors as part of a project called NetQuakes.
NetQuakes will install a half-dozen seismometers in the Spokane area by the end of June, mostly in volunteers’ homes, to help improve understanding of what lies beneath the city. (more…)
Compared to normal cells, cancer cells have a prodigious appetite for glucose, the result of a shift in cell metabolism known as aerobic glycolysis or the “Warburg effect.” Researchers focusing on this effect as a possible target for cancer therapies have examined how biochemical signals present in cancer cells regulate the altered metabolic state.

Researchers from North Carolina State University have found a way to create much slimmer thin-film solar cells without sacrificing the cells’ ability to absorb solar energy. Making the cells thinner should significantly decrease manufacturing costs for the technology.
“We were able to create solar cells using a ‘nanoscale sandwich’ design with an ultra-thin ‘active’ layer,” says Dr. Linyou Cao, an assistant professor of materials science and engineering at NC State and co-author of a paper describing the research. “For example, we created a solar cell with an active layer of amorphous silicon that is only 70 nanometers (nm) thick. This is a significant improvement, because typical thin-film solar cells currently on the market that also use amorphous silicon have active layers between 300 and 500 nm thick.” The “active” layer in thin-film solar cells is the layer of material that actually absorbs solar energy for conversion into electricity or chemical fuel.

The Microsoft Local Impact Map helps nonprofits illustrate the difference they make in a visual, dynamic way.
REDMOND, Wash. — June 28, 2012 — The benefits of storytelling and the need for nonprofits to communicate their impact to various audiences has been a focus of late among nonprofit organizations and corporate social responsibility groups. It has been a hot topic at recent social innovation industry events such as Nonprofit Technology Network, the Cause Marketing Forum and the Social Innovation Summit. (more…)
COLLEGE PARK, Md. –– A University of Maryland scientist and an undergraduate Indian student he mentored in India have uncovered a major new finding about El Nino — the cyclical climate event that appears every 2-7 years, sometimes with major global weather impacts such as massive flooding in some regions and severe droughts in others and resulting major economic impacts.

Berkeley Lab scientists, major contributors to the ATLAS experiment at the Large Hadron Collider, explain what the excitement is about
CERN, the European Organization for Nuclear Research headquartered in Geneva, Switzerland, will hold a seminar early in the morning on July 4 to announce the latest results from ATLAS and CMS, two major experiments at the Large Hadron Collider (LHC) that are searching for the Higgs boson. Both experimental teams are working down to the wire to finish analyzing their data, and to determine exactly what can be said about what they’ve found.
“We do not yet know what will be shown on July 4th,” says Ian Hinchliffe, a theoretical physicist in the Physics Division at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), who heads the Lab’s participation in the ATLAS experiment. “I have seen many conjectures on the blogs about what will be shown: these are idle speculation. Things are moving very fast this week, and it’s an exciting time at CERN. Many years of hard work are coming to fruition.” (more…)
HAWAI’I ISLAND, Hawai‘’— Three of Hawai’i Island’s rarest endangered forest birds have been detected at lower elevations of Hakalau Forest National Wildlife Refuge for the first time in 30 years.
The rediscovery of the three endangered species at lower elevations than expected was part of a joint U.S. Fish and Wildlife Service and U.S. Geological Survey project on the potential impact of climate change on avian disease. All three species are believed to be highly susceptible to mosquito-transmitted diseases, limiting their distribution to the cooler, higher elevations of the refuge. These new observations significantly extend the current known range of these species at the refuge. (more…)
