Taming the Butterfly

An interesting study by Netpop Research entitled Social Face-Off : A Comparison of U.S. and China Social Media Use finds that people in China are more involved in every type of social media activity of which they studied.  First, some general facts about the two internet communities: of the broadband users age 13 and above, the Chinese have a much younger, more educated internet population than the U.S.  They also spend more time online per weekday.

As Nasa prepares to retire its fleet of space shuttles, it is encouraging private companies to build new rockets to get its astronauts into orbit. Among the firms landing huge contracts to build the next generation of spacecraft is SpaceX. Science correspondent David Shukman visited the company's rocket factory in California for a look inside the prototype capsule.

Exposure to air pollution early in life and when a woman gives birth to her first child may alter her DNA and may be associated with premenopausal breast cancer later in life, researchers at the University at Buffalo have shown.

Chemical changes in tree leaves subjected to warmer, drier conditions that could result from climate change may reduce the availability of soil nutrients, according to a Purdue University study.

Google recently announced that it will help fund groundbreaking research by computer scientists and economists at Tel Aviv University.  The Blavatnik School of Computer Science is attempting to help computers make better decisions using a term they dubbed "regret." Head of the program Professor Yishay Mansour began this project earlier this year at the International Conference on Learning Theory in Haifa, Israel.  He and the other researchers are working on algorithms that would allow computers to learn from their past failures in an effort to make better predictions.  This is referred to as "minimizing virtual regret" by Mansour. "If the servers and routing systems of the Internet could see and evaluate all the relevant variables in advance, they could more efficiently prioritize server resource requests, load documents and route visitors to an Internet site, for instance," says Mansour.

While many Western retail giants have failed to translate their American success in this booming economy, Apple is winning simply by being Apple.

A recently released report of the General Social Survey, conducted by NORC at the University of Chicago, shows that for the first time since 1972, more Americans say that their financial situation has gotten worse in recent years rather than better. Understandably, also for the first time since 1972, the percentage of Americans saying that they are "not at all" satisfied with their financial situation (31.5%) notably exceeds those saying they are "pretty well" satisfied (23.4%).

Drug-resistant strains of Staphylococcus aureus, a bacteria linked to a wide range of human diseases, are present in meat and poultry from U.S. grocery stores at unexpectedly high rates, according to a nationwide study by the Translational Genomics Research Institute (TGen).

Easy-to-follow recipes for radioactive compounds like those found in nuclear fuel storage pools, liquid waste containment areas and other contaminated aqueous environments have been developed by researchers at Sandia National Laboratories.

The enormous kite, which looks like a paraglider, works in tandem with the ship's engines, cutting back on fuel consumption, costs, and carbon footprint. "Using kites you can harness more energy than with any other type of wind-powered equipment," said German inventor Stephan Wrage, whose company SkySails is looking for lift-off on the back of worldwide efforts to boost renewable energy.

German Economy Minister Rainer Bruederle said Friday that a switch from nuclear power to alternative forms of energy could cost Europe's top economy up to two billion euros ($2.9 billion) per year.

The breakthrough is the first-ever transfer, or teleportation, of a particular complex set of quantum information from one point to another, opening the way for high-speed, high-fidelity transmission of large volumes of information, such as quantum encryption keys, via quantum communications networks.

Scientists at the NRL Materials Science and Technology Division are providing solid evidence that there is a new route towards developing novel, lightweight energy storage devices. By moving away from centuries of caustic, hazardous aqueous-based battery cells and instead using non-volatile, thermally-stable ionic liquids, scientists predict multiple new types of batteries. Rather than depend on highly acidic electrolytes, ionic liquids are used to create a solid polymer electrolyte composed of an ionic liquid and polyvinyl alcohol, developing novel types of solid state batteries with discharge voltages ranging up to 1.8 volts.

GM's 135 patents represented nearly 14 percent of the 1,881 US patents obtained by 700 organizations in 2010, according to an analysis by the Clean Energy Patent Growth Index.

Renren, China's most popular social network, filed for an initial public offering in the United States on Friday hoping to raise as much as $583 million.

The exploitation and utilization of new energy sources are considered to be among today's major challenges. Solar energy plays a central role, and its direct conversion into chemical energy, for example hydrogen generation by water splitting, is one of its interesting variants. Titanium oxide-based photocatalysis is the presently most efficient, yet little understood conversion process. In cooperation with colleagues from Germany and abroad, scientists of the KIT Institute for Functional Interfaces (IFG) have studied the basic mechanisms of photochemistry by the example of titania and have presented new detailed findings.

essays in this book reflect pioneering efforts to study the global movement of ideas and institutions. They deal with topics of significant contemporary importance: initiatives to address the AIDS epidemic in East Africa; to protect the peoples and ecosystems of the Amazon; to advance the "truth and reconciliation" process in South Africa and in other areas of great conflict; to promote "civil society" in Eastern Europe and Central Asia; to advocate for environmental protection in the United States, Great Britain, Germany, and Japan; and to spread Rotary Clubs and encourage "social entrepreneurship" throughout the world. These essays highlight a wide range of research, paying close attention to the realities of particular situations and to current thinking about general processes.

Macro health news breaks when there is a natural disaster, a scientific breakthrough, or a new twist in a policy debate (see: "ACOs"). I read up on the facts and try to make sense of the latest turn of events, but usually from a comfortable distance. Micro health news breaks when a loved one gets a serious diagnosis. Then I follow the unfolding health care story with intensity and I care more about the outcome.

A high-tech entrepreneur has unveiled plans to launch the world's most powerful rocket since man went to the moon.

A new report on young people's use of social networking and cyber safety reveals that young people may be more aware and better able to manage online risks than their parents commonly think.
