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.

Furthermore, the NSA has designated more than 150 colleges and universities as centres of excellence, which qualifies students and faculty members for extra support. It can also fund research indirectly through other agencies, and so the total amount of support may be much higher. A leaked budget document says that the NSA spends more than $400 million a year on research and technology — although only a fraction of this money might go to research outside the agency itself.

Many US researchers, especially those towards the basic-research end of the spectrum, are comfortable with the NSA’s need for their expertise.

“I understand what’s in the newspapers,” he says, “but the NSA is funding serious long-term fundamental research and I’m happy they’re doing it.”

But it took a long time for solar sails to go from concept to reality. The first successful demonstration of the propulsion system didn't come until 2010, when Japan's Ikaros probe deployed its 46-foot-wide (14 m) sail and became the first craft ever to cruise through space on the backs of photons.

The $27 million Sunjammer mission, which takes its name from the Arthur C. Clarke story, will use a sail built by California-based company L'Garde that measures 124 feet (38 m) on a side. The sail, made of an advanced material called Kapton, is just 5 microns (about 0.0002 inches) thick. It weighs less than 70 pounds (32 kilograms) and packs down to the size of a dishwasher, NASA officials have said.

Beginning in February, large nonhuman subjects have received weekly injections of cancer cells into their livers, creating a consistent model in a "controlled environment." This month, the subjects will undergo MRIs to determine whether they now have liver cancer. If affirmative, the Kanzius noninvasive radio-wave cancer treatment will be administered, allowing data to be collected and analyzed. The success of these tests is mandatory to move forward in approaching the U.S. Food and Drug Administration and ultimately advancing to human trials.

Presence is widely accepted as the key concept to be considered in any research involving human interaction with Virtual Reality (VR). Since its original description, the concept of presence has developed over the past decade to be considered by many researchers as the essence of any experience in a virtual environment. The VR generating systems comprise two main parts: a technological component and a psychological experience. The different relevance given to them produced two different but coexisting visions of presence: the rationalist and the psychological/ecological points of view. The rationalist point of view considers a VR system as a collection of specific machines with the necessity of the inclusion of the concept of presence. The researchers agreeing with this approach describe the sense of presence as a function of the experience of a given medium (Media Presence). The main result of this approach is the definition of presence as the perceptual illusion of non-mediation produced by means of the disappearance of the medium from the conscious attention of the subject. At the other extreme, there is the psychological or ecological perspective (Inner Presence). Specifically, this perspective considers presence as a neuropsychological phenomenon, evolved from the interplay of our biological and cultural inheritance, whose goal is the control of the human activity. Given its key role and the rate at which new approaches to understanding and examining presence are appearing, this chapter draws together current research on presence to provide an up to date overview of the most widely accepted approaches to its understanding and measurement.

Closer to home, private industries like Mars One seek to establish a permanent settlement on the Red Planet. At the Smithsonian Magazine's "The Future is Here Festival" in Washington, D.C. this month, former astronaut Mae Jemison and NASA engineer Adam Steltzner spoke optimistically about the future of manned space exploration

Although the idea that bacteria — and life — could hitch a ride on traveling rocks to spread life to other planets is not new, Steltzner suggested a deliberate program that sounds more like science fiction than science fact. Such bacteria could carry our genome and the instructions to reassemble it after landing on a planet (and, one assumes, after the planet has been terraformed to support such life). Steltzner described the process as "printing human beings organically over time."

In addition to curiosity-motivated exploration, Steltzner pointed out that as long as humans remain on a single planet, we are at risk of extinction when disaster strikes. "Our real estate portfolio suffers from a concentration of risk," he said.

Like a perfectly addictive drug, almost every aspect of the television viewing experience grabs and holds your brain’s attention, which explains why it’s so tough to stop watching after just one (or three) episodes of Orange is the New Black.

Characters run or shout or shoot accompanied by sound effects and music. No two moments are quite alike. To your brain, this kind of continuously morphing sensory stimulation is pretty much impossible to ignore, explains Robert F. Potter, Ph.D., director of the Institute for Communication Research at Indiana University.

“Our brains are hardwired to automatically pay attention to anything that’s new in our environment, at least for a brief period of time,” he explains. And it’s not just humans; all animals evolved this way in order to spot potential threats, food sources, or reproductive opportunities, Potter says.

The results: The patients who listened to music had less anxiety and lower cortisol than people who took drugs. Levitin cautioned that this is only one study, and more research needs to be done to confirm the results, but it points toward a powerful medicinal use for music.

Among participants, the researchers found synchronization in several key brain areas, and similar brain activity patterns in different people who listen to the same music. This suggests that the participants not only perceive the music the same way, but, despite whatever personal differences they brought to the table, there's a level on which they share a common experience.

On July 12, 1939, a few months before the beginning of World War II in Europe, Szilárd and Wigner visited Einstein[74] and they explained the possibility of atomic bombs, to which pacifist Einstein replied: Daran habe ich gar nicht gedacht ("I had not thought of that at all").[75] Einstein was persuaded to lend his prestige by writing a letter with Szilárd to President Franklin D. Roosevelt to alert him of the possibility. The letter also recommended that the U.S. government pay attention to and become directly involved in uranium research and associated chain reaction research. The letter is believed to be "arguably the key stimulus for the U.S. adoption of serious investigations into nuclear weapons on the eve of the U.S. entry into World War II".[76] In addition to the letter, Einstein used his connections with the Belgian Royal Family[77] and the Belgian queen mother[72] to get access with a personal envoy to the White House's Oval Office.[72] President Roosevelt could not take the risk of allowing Hitler to possess atomic bombs first. As a result of Einstein's letter and his meetings with Roosevelt, the U.S. entered the "race" to develop the bomb, drawing on its "immense material, financial, and scientific resources" to initiate the Manhattan Project. It became the only country to successfully develop an atomic bomb during World War II. For Einstein, "war was a disease ... [and] he called for resistance to war." By signing the letter to Roosevelt he went against his pacifist principles.[78] In 1954, a year before his death, Einstein said to his old friend, Linus Pauling, "I made one great mistake in my life—when I signed the letter to President Roosevelt recommending that atom bombs be made; but there was some justification—the danger that the Germans would make them ..."[79]

While viewers enjoy watching episodes of their favorite TV shows back-to-back, advertisers suffer because video-on-demand (VOD) providers do not want to alienate their viewers by running advertisements.

Critics say that the company’s reliance on subscriptions alone poses a problem, because an increase in price will translate into lost subscribers.

This loyal customer base can also be used to leverage the findings of a study by Annalect, – Omnicom Media Group’s marketing technology platform – which suggests that binge viewers don’t actually mind ads.
