Taming the Butterfly

People who suffer from irregular heartbeat could see their episodes cut in half if they do yoga regularly, according to a study released Saturday in the United States.

In this July 15, 2008 file photo, a sign advocating buying fresh and local in the Shenandoah Valley is tacked on a bulletin board at the Shenandoah Valley Produce auction in Dayton, Va. A heightened consumer interest in produce grown nearby, which many assume to mean fresher food, fewer chemicals, and grown smaller farms, has led to popular use of the word on displays and menus. While good for many farmers, the trend can be misleading for consumers, as there is no one or regulated meaning for "local".

Purdue University researchers have developed a set of propagation and production protocols that will help Indiana greenhouse growers bring a tropical plant into flower for spring sales.

Cornell researchers are calling on their colleagues around the world to focus on how aging global populations will intersect with climate change and calls for environmental sustainability.

A new paper appearing in the Proceedings of the National Academy of Sciences (PNAS) suggests that people, governments, and institutions that shape the way people interact may be just as important for determining environmental conditions as the environmental processes themselves.

According to a report released by Freedom House titled Freedom on the Net 2011, Iran is the worst country when it comes to online freedom.  The top three countries, in order, are Estonia, The United States and Germany. The study judged countries based on three specific criteria: Obstacles to internet access, limits on content and violations of user rights.  They assigned each country a numerical score based on those criteria.  Countries scoring from 0-30 are designated "free," countries scoring from 31-60 are designated "party free" and those with score of 61-100 are labelled "not free."

A study recently released by a team from Northwestern University and the University of Arizona shows that religion and religious affiliations may be on the verge of extinction in the nine countries studied. Utilizing a mathematical model of nonlinear dynamics, the team analyzed data from censuses taken in nine different countries dating as far back as a century.

As Iran's nuclear plant attack and Chinese-based hackers attacking Morgan Stanley demonstrate how the Internet can wreak havoc on business and governments, a new paper by a fellow at Rice University's Baker Institute for Public Policy hypothesizes what an all-out cyberwar between the U.S. and China might look like.

Scientists have observed a "super-aggregation" of more than 300 humpback whales gorging on the largest swarm of Antarctic krill seen in more than 20 years in bays along the Western Antarctic Peninsula.

In Innovation Deep Dive, Lisa Strausfeld from Pentagram has contrasted the drivers and the impact of innovation of various countries by way of an interactive line ranking. The visualization uses quite a large set of different datasets, ranging from Gallup and business schools reports, to the usual suspects like the UNESCO and the World Bank. The interface requires some trial-and-error to get used to (e.g. the data categories at the top are clickable), but creates a compelling overview of how different nations actually perform versus how their business executives perceive the same issue.

After recently undertaking a journey to walk -- not fly -- across the United States in the "Grounded" storyline and reconnect with the country and everyday Americans, Superman appears to be taking another step that could have major implications for his national identity: in Action Comics #900... ...Superman announces that he is going to give up his U.S. citizenship. Despite very literally being an alien immigrant, Superman has long been seen as a patriotic symbol of "truth, justice, and the American way," from his embrace of traditional American ideals to the iconic red and blue of his costume. What it means to stand for the "American way" is an increasingly complicated thing, however, both in the real world and in superhero comics, whose storylines have increasingly seemed to mirror current events and deal with moral and political complexities rather than simple black and white morality.

John Hunter puts all the problems of the world on a 4′x5′ plywood board - and lets his 4th-graders solve them. At TED2011, he explains how his World Peace Game engages schoolkids, and why the complex lessons it teaches - spontaneous, and always surprising - go further than classroom lectures can.

High-performance nanotech materials arrayed on a flat panel platform demonstrated seven to eight times higher efficiency than previous solar thermoelectric generators, opening up solar-thermal electric power conversion to a broad range of residential and industrial uses, a team of researchers from Boston College and MIT report in the journal Nature Materials.

People who look at the past through rose-tinted glasses are happier than those who focus on negative past experiences and regrets, according to a new study published in the journal Personality and Individual Differences. The study helps explain why personality has such a strong influence on a person's happiness. The findings suggest that persons with certain personality traits are happier than others because of the way they think about their past, present and future.

A new study from the Karolinska Institute and Stockholm School of Economics shows that the brain has built-in mechanisms that trigger an automatic reaction to someone who refuses to share. In the study publishing next week in the online open access journal PLoS Biology, the subjects' sense of justice was challenged in a two-player monetary fairness game, and their brain activity was simultaneously measured using functional magnetic resonance imaging (fMRI). When bidders made unfair suggestions as to how to share the money, they were often punished by their partners even if it cost them. This reaction to unfairness could be reduced by targeting one specific brain region, the amygdala.

A two-year energy audit of Hamilton schools has identified energy conservation measures that could reduce their energy costs by almost $2.4 million annually. The audit was conducted by engineering faculty and students at McMaster University.

A new source of biomass grown on unused land could help the UK meet renewable energy targets without affecting food production or the environment, according to the results of a new study.

The high cost of health care is deterring parents from taking their children to the doctor or buying prescription medication, regardless of how much money they make or whether they have health insurance, according to a study to be presented Sunday, May 2, at the Pediatric Academic Societies (PAS) annual meeting in Denver.
