For patients and their families, embryonic stem cell research offers the hope of cures for chronic and debilitating conditions, such as juvenile diabetes, Alzheimer’s disease, Parkinson’s disease, spinal cord injuries and blindness. For scientists, it represents a revolutionary path to discovering the causes and cures for many more human maladies. Embryonic stem cells are pluripotent, that is, they have the unique ability to develop into any of the 220 cell types in the human body. In addition to their versatility, embryonic stem cells are easier to grow in the laboratory than adult stem cells.

But many opponents, including some religious leaders, believe that stem cell research raises the same moral issues as abortion. Furthermore, opponents maintain that scientists have other promising ways of reaching the same goals, including non-controversial adult stem cell research.

Accommodated as we are to mass media, we must work to imagine the impact of commercial radio broadcasting in its early years. From the late 1800s, new electronic devices had been expanding the realm of shared human experience — people conversed on telephones, sent news through telegrams, played records on phonographs, and enjoyed films in local theaters. But until the radio, nothing offered such widely shared simultaneous mass experience. By turning on your radio set, you could listen to a jazz band, baseball game, religious service, even a president’s speech, live, along with millions of fellow listeners.

The bold new era of content distribution and technological efficiency has served up entire, original award-winning series series like Netflix' House of Cards and Orange is the New Black for consumption in one sitting, if the viewer desires.

Quite frankly, we've never had it so good.

After analyzing more than 3 million tweets, gigabytes of YouTube content and thousands of blog posts, a new study finds that social media played a central role in shaping political debates in the Arab Spring.

“Our evidence suggests that social media carried a cascade of messages about freedom and democracy across North Africa and the Middle East, and helped raise expectations for the success of political uprising,” said Philip Howard, the project lead and an associate professor in communication at the University of Washington.  “People who shared interest in democracy built extensive social networks and organized political action. Social media became a critical part of the toolkit for greater freedom.”

In a world where knowledge is revered and innovation equals progress, those able to bring forth greater insight and understanding are destined to make their mark and blaze a trail to greater enlightenment. "Critical thinking as an attitude is embedded in Western culture. There is a belief that argument is the way to finding truth," observes Adrian West, research director at the Edward de Bono Foundation U.K., and a former computer science lecturer at the University of Manchester. "Developing our abilities to think more clearly, richly, fully—individually and collectively—is absolutely crucial [to solving world problems]." To be sure, history is filled with tales of remarkable thinkers who have defined and redefined our world views: Sir Isaac Newton discovering gravity; Voltaire altering perceptions about society and religious dogma; and Albert Einstein redefining the view of the universe. But in an age of computers, video games, and the Internet, there's a growing question about how technology is changing critical thinking and whether society benefits from it. Although there's little debate that computer technology complements—and often enhances—the human mind in the quest to store information and process an ever-growing tangle of bits and bytes, there's increasing concern that the same technology is changing the way we approach complex problems and conundrums, and making it more difficult to really think. "We're exposed to [greater amounts of] poor yet charismatic thinking, the fads of intellectual fashion, opinion, and mere assertion," says West. "The wealth of communications and information can easily overwhelm our reasoning abilities." What's more, it's ironic that ever-growing piles of data and information do not equate to greater knowledge and better decision-making. What's remarkable, West says, is just "how little this has affected the quality of our thinking." According to the National Endowment for the Arts, literary reading declined 10 percentage points from 1982 to 2002 and the rate of decline is accelerating. Many, including Patricia Greenfield, a UCLA distinguished professor of psychology and director of the Children's Digital Media Center, Los Angeles, believe that a greater focus on visual media exacts a toll. "A drop-off in reading has possibly contributed to a decline in critical thinking," she says. "There is a greater emphasis on real-time media and multitasking rather than focusing on a single thing." Nevertheless, the verdict isn't in and a definitive answer about how technology affects critical thinking is not yet available. Instead, critical thinking lands in a mushy swamp somewhere between perception and reality; measurable and incomprehensible. It's largely a product of our own invention—and a subjective one at that. And although technology alters the way we see, hear, and assimilate our world—the act of thinking remains decidedly human. Back to Top Rethinking Thinking Arriving at a clear definition for critical thinking is a bit tricky. Wikipedia describes it as "purposeful and reflective judgment about what to believe or what to do in response to observations, experience, verbal or written expressions, or arguments." Overlay technology and that's where things get complex. "We can do the same critical-reasoning operations without technology as we can with it—just at different speeds and with different ease," West says. What's more, while it's tempting to view computers, video games, and the Internet in a monolithic good or bad way, the reality is that they may be both good and bad, and different technologies, systems, and uses yield entirely different results. For example, a computer game may promote critical thinking or diminish it. Reading on the Internet may ratchet up one's ability to analyze while chasing an endless array of hyperlinks may undercut deeper thought.

A thoroughknowledge of the community is required to be able to understand the group, as well asunderstand the individual’s place in the whole. This knowledge allows a group to build asocially imagined concept of communal belief. It creates a method for demarcating who is and isnot an insider, and allows the group to come to terms with their shared ‘canonical’ text(s).

Much of the organization and mobilization occurred through the Internet, particularly on social media such as Facebook and Twitter. But social media also played a vital role as a democratic model. Its inclusive space indirectly taught lessons in democracy to a wide sector of Egyptian youth that was not necessarily politically inclined. When the right moment arrived, they were ready to join the revolt.

What happened in January 2011 in Egypt did not start in January 2011. It began at least ten years earlier, and it’s not over yet

The main catalyst for the January 25 revolution was the Internet, so it may be accurate to describe this as an Internet-based revolution. Not that the Internet was the only factor involved, or that Internet users were the only ones protesting. But the Internet was the tool that showed every dissident voice in Egypt that he or she is not alone, and is indeed joined by at least hundreds of thousands who seek change.

The Egyptian resistance used web tools as well as physical space, and most importantly, they did so by looking at the intersection of both. They used the web to inform people how to behave in physical space, e.g., what to do with tear gas containers, who should stand in front of the crowds and how the crowds should move about the city. It makes little sense to argue about whether these are social media revolutions or not. Instead, we should recognize them as augmented revolutions. Only then can we debate just how and how much of a role the digital aspect played.
