A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has discovered that microscopic bacteria have a lot in common with earthquakes — when it comes to their jolting movements.
In a new study published in the peer-reviewed Proceedings of the National Academy of Sciences, the scientists also report that a molecular “glue” produced by the bacteria to help them adhere to surfaces also acts as a sort of transportation lubricant, helping them move and organize into rudimentary social structures. These discoveries, they say, could lead to new ways to combat harmful microbes in the long term. (more…)
Like the impact of an elephant herd grazing on grassland, multinational banks shape the financial environment to an extent that far outweighs their small number. And like a contagious person on a transnational flight, when these giant, interconnected banks succumb to financial ills, they are uniquely positioned to infect wide swaths of the financial system.
Researchers from Princeton University, the Bank of England and the University of Oxford applied methods inspired by ecosystem stability and contagion models to banking meltdowns and found that large national and international banks wield an influence and potentially destructive power that far exceeds their actual size.

When eight cities and five provinces in China were asked by the central government to develop a plan to become “low carbon,” many had no idea what to do. Some planted trees. Others decided to build up a solar panel industry. One city even thought about building a lake to be more “green.” Local government leaders were at a loss as to how to reduce their carbon emissions.
In 2008, China’s National Development and Reform Commission (NDRC) and the U.S. Department of Energy (DOE) initiated a joint effort to address energy and environmental challenges facing urban centers in both countries. Lawrence Berkeley National Laboratory’s China Energy Group was tasked by DOE to identify and recommend best practices, tools and technologies. With nearly 25 years experience analyzing energy use in China, the China Energy Group has tailored a variety of resources to help local Chinese officials turn government mandates into practical how-to guides for understanding their energy usage and reducing their carbon dioxide emissions.

College Park, MD – A University of Maryland study projects that Washington, D.C. city and federal property could suffer billions of dollars in damage if sea level rise from global warming increases over the next century. Potential for significant damage will be even greater in the event of extreme weather like Hurricane Sandy
The study by Civil and Environmental Engineering Professor Bilal Ayyub, Haralamb Braileanu and Naeem Qureshi, of the Clark School of Engineering’s Center for Technology and Systems Management, looks at possible long term effects of projected sea level rise on Washington, D.C. real-estate property and government infrastructure. They conclude that over the next 100 years, continuing sea level rise could cause damages of more than $24.6 billion to Washington’s commercial property, museums, and government agencies. (more…)
Developing a shared sense of global community could help reduce major episodes of violence
In the tribal societies of the Amazon forest, violent conflict accounted for 30 percent of all deaths before contact with Europeans, according to a recent study by University of Missouri anthropologist Robert Walker. Understanding the reasons behind those altercations in the Amazon sheds light on the instinctual motivations that continue to drive human groups to violence, as well as the ways culture influences the intensity and frequency of violence.
“The same reasons – revenge, honor, territory and jealousy over women – that fueled deadly conflicts in the Amazon continue to drive violence in today’s world,” said Walker, lead author and assistant professor of anthropology in MU’s College of Arts and Science. “Humans’ evolutionary history of violent conflict among rival groups goes back to our primate ancestors. It takes a great deal of social training and institutional control to resist our instincts and solve disputes with words instead of weapons. Fortunately, people have developed ways to channel those instincts away from actual deadly conflict. For example, sports and video games often involve the same impulses to defeat a rival group.” (more…)

At the heart of the immune system that protects our bodies from disease and foreign invaders is a vast and complex communications network involving millions of cells, sending and receiving chemical signals that can mean life or death. At the heart of this vast cellular signaling network are interactions between billions of proteins and other biomolecules. These interactions, in turn, are greatly influenced by the spatial patterning of signaling and receptor molecules. The ability to observe signaling spatial patterns in the immune and other cellular systems as they evolve, and to study the impact on molecular interactions and, ultimately, cellular communication, would be a critical tool in the fight against immunological and other disorders that lead to a broad range of health problems including cancer. Such a tool is now at hand. (more…)
