researchers and some start-ups are already preparing the next, even more intrusive wave of computing: ingestible computers and minuscule sensors stuffed inside pills.

some people on the cutting edge are already swallowing them to monitor a range of health data and wirelessly share this information with a doctor

For years, politicians wanting to block legislation on climate change have bolstered their arguments by pointing to the work of a handful of scientists who claim that greenhouse gases pose little risk to humanity.

One of the names they invoke most often is Wei-Hock Soon, known as Willie, a scientist at the Harvard-Smithsonian Center for Astrophysics who claims that variations in the sun’s energy can largely explain recent global warming.

He has accepted more than $1.2 million in money from the fossil-fuel industry over the last decade while failing to disclose that conflict of interest in most of his scientific papers. At least 11 papers he has published since 2008 omitted such a disclosure, and in at least eight of those cases, he appears to have violated ethical guidelines of the journals that published his work.

Hawking told the audience that Earth's cataclysmic end may be hastened by humankind, which will continue to devour the planet’s resources at unsustainable rates

“Although the chance of a disaster to planet Earth in a given year may be quite low, it adds up over time, and becomes a near certainty in the next thousand or ten thousand years. By that time we should have spread out into space, and to other stars, so a disaster on Earth would not mean the end of the human race.”

“I think the development of full artificial intelligence could spell the end of the human race,” Hawking told the BBC in a 2014 interview that touched upon everything from online privacy to his affinity for his robotic-sounding voice.

GIVEN the complexities of the modern world, we all have to rely on expert opinion. Are G.M.O. foods safe? Is global warming real? Should children be vaccinated for measles? We don’t have the time or the training to adjudicate these questions ourselves. We defer to the professionals.

And to find out what the experts think, we typically rely on the news media. This creates a challenge for journalists: There are many issues on which a large majority of experts agree but a small number hold a dissenting view. Is it possible to give voice to experts on both sides — standard journalistic practice — without distorting the public’s perception of the level of disagreement?

This can be hard to do. Indeed, critics argue that journalists too often generate “false balance,” creating an impression of disagreement when there is, in fact, a high level of consensus. One solution, adopted by news organizations such as the BBC, is “weight of evidence” reporting, in which the presentation of conflicting views is supplemented by an indication of where the bulk of expert opinion lies.

I am not a professional and this is not a diagnosis. My post is not intended to persuade anyone or provide a comprehensive description of NPD. I am speaking purely from decades of dealing with NPD and sharing strategies that were helpful for me in coping and predicting behavior.

Here are a few things to keep in mind:

1) It’s not curable and it’s barely treatable. He is who he is. There is no getting better, or learning, or adapting. He’s not going to “rise to the occasion” for more than maybe a couple hours. So just put that out of your mind.

The test of replicability, as it’s known, is the foundation of modern research. Replicability is how the community enforces itself. It’s a safeguard for the creep of subjectivity. Most of the time, scientists know what results they want, and that can influence the results they get. The premise of replicability is that the scientific community can correct for these flaws.

But now all sorts of well-established, multiply confirmed findings have started to look increasingly uncertain. It’s as if our facts were losing their truth: claims that have been enshrined in textbooks are suddenly unprovable.

This phenomenon doesn’t yet have an official name, but it’s occurring across a wide range of fields, from psychology to ecology.

The wealthy, says Smith, spend their days establishing an “economy of greatness,” one founded on “luxury and caprice” and fueled by “the gratification of their own vain and insatiable desires.” Any broader benefit that accrues from their striving is not the consequence of foresight or benevolence, but “in spite of their natural selfishness and rapacity.” They don’t do good, they are led to it.

In other words, the invisible hand did not solve the problem of politics by making politics altogether unnecessary. “We don’t think government can solve all our problems,” President Obama said in his convention address, “But we don’t think that government is the source of all our problems.” Smith would have appreciated this formulation. For him, whether government should get out of the way in any given matter, economic or otherwise, was a question for considered judgment abetted by scientific inquiry.

What it did not do, however, was void any proposal outright, much less prove that all government activity was counterproductive. Smith held that the sovereign had a role supporting education, building infrastructure and public institutions, and providing security from foreign and domestic threats — initiatives that should be paid for, in part, by a progressive tax code and duties on luxury goods. He even believed the government had a “duty” to protect citizens from “oppression,” the inevitable tendency of the strong to take advantage of the ignorance and necessity of the weak.

How did American culture arrive at these moments? A new research paper by Nick Haslam, a professor of psychology at the University of Melbourne, Australia, offers as useful a framework for understanding what’s going on as any I’ve seen. In “Concept Creep: Psychology's Expanding Concepts of Harm and Pathology,”

concepts like abuse, bullying, trauma, mental disorder, addiction, and prejudice, “now encompass a much broader range of phenomena than before,”expanded meanings that reflect “an ever-increasing sensitivity to harm.”

“they also have potentially damaging ramifications for society and psychology that cannot be ignored.”

Most people readily believe that they themselves are essentially fully independent thinkers, and that closed-mindedness, intellectual inflexibility and an irrational commitment to pre-conceived thinking dwells only in the feeble minds of others. Think about it: When was the last time in the course of discussion that someone admitted to you something like, “You’re right, I have just blindly swallowed all of the positions and cultural mores of my milieu” or, “Yes, I agree that no amount of oppositional information will ever dissuade me from the beliefs I hold?” No one is immune from this state of affairs, and it requires courage and perpetual vigilance to even venture outside of the intellectual echo chamber that most of us inhabit.

There are those who believe that the scientific community is uniquely positioned to avoid these pitfalls. They suggest that the system of peer review is inherently self-critical, and as such is structurally quarantined from bias. Some scientists think otherwise and note that science, in as much as it is conducted by human beings, is subject to the same partiality as every other endeavor.

like the communist party under Lenin, science is [in its own eyes] infallible because its judgments are collective. Critics are unneeded, and since they are unneeded, they are not welcome.

For decades, a small group of scientific dissenters has been trying to shoot holes in the prevailing science of climate change, offering one reason after another why the outlook simply must be wrong.

But the worst possible place to resolve such issues is the political arena." Alexander Flax, Potomac, MD Read Full Comment » Post a Comment » Over time, nearly every one of their arguments has been knocked down by accumulating evidence, and polls say 97 percent of working climate scientists now see global warming as a serious risk.

They acknowledge that the human release of greenhouse gases will cause the planet to warm. But they assert that clouds — which can either warm or cool the earth, depending on the type and location — will shift in such a way as to counter much of the expected temperature rise and preserve the equable climate on which civilization depends.

At gatherings of climate change skeptics on both sides of the Atlantic, Dr. Lindzen has been treated as a star. During a debate in Australia over carbon taxes, his work was cited repeatedly. When he appears at conferences of the Heartland Institute, the primary American organization pushing climate change skepticism, he is greeted by thunderous applause.

In less than a year on television (and with a chirpy voice, a weakness for gesticulation and a tendency to drop honors-thesis words like “signifier” into casual conversation), Mr. Hayes has established himself as Generation Y’s wonk prince of the morning political talk-show circuit.

“He is never doctrinaire,” Mr. Leo said in an interview. Both punk fans and “Up” fans are “suspicious of any authority,” he said, and appreciate that Mr. Hayes “is always willing to challenge his own assumptions, and the received wisdom on both sides of the aisle.”

Social media, in fact, have played an unusually important role in driving traffic to the program, an MSNBC spokeswoman said. About 45 percent of the visitors to the program’s Web site, which contains complete episodes, linked through sites like Facebook and Twitter. In April, those users spent an average of 51 minutes on the site each visit.

Lately inequality has re-entered the national conversation. Occupy Wall Street gave the issue visibility, while the Congressional Budget Office supplied hard data on the widening income gap. And the myth of a classless society has been exposed: Among rich countries, America stands out as the place where economic and social status is most likely to be inherited.

some indicators of social dysfunction have improved dramatically even as traditional families continue to lose ground. As far as I can tell, Mr. Murray never mentions either the plunge in teenage pregnancies among all racial groups since 1990 or the 60 percent decline in violent crime since the mid-90s. Could it be that traditional families aren’t as crucial to social cohesion as advertised?

To be fair, the new book at the heart of the conservative pushback, Charles Murray’s “Coming Apart: The State of White America, 1960-2010,” does highlight some striking trends. Among white Americans with a high school education or less, marriage rates and male labor force participation are down, while births out of wedlock are up. Clearly, white working-class society has changed in ways that don’t sound good.

a new app for the treatment of phobias. You stare at pictures of dental drills, snakes or airplane interiors, depending on your affliction, and these totems of menace  — interspersed with reassuring images of teddy bears  — gradually cease to provoke you.

Another person wrote: “I am terrified of string. You know, when you have a loose string hanging off your clothes. Most people just shrug it off.” (Who knew?) “But I go insane until I get it off the item.”Balloons, pigeons, boats, bald men, cotton batten, garden peas. These have all acted as the culprits, according to reports I’ve received, in making otherwise reasonable human beings assume the visage of Edvard Munch’s screamer. People fear chins, condiments, towels, cut fruit.The object appears to be irrelevant, in many cases, beyond its subconscious assignation as the Very Thing to Fear.

One attempts to find logical causes for phobia at one’s peril.

In the end, Mitt Romney didn’t lose the Michigan primary, and he didn’t lose his near-lock on the Republican nomination. Rick Santorum isn’t going away, but a solid victory in Michigan and an easy win in Arizona leaves the Romney campaign’s basic math more or less intact. If their candidate can keep winning contests in the West and Northeast and holding serve across the Midwest, Romney’s rivals won’t be able to stop him from grinding out a victory.

Thanks to his own smooth evasiveness and the blunders of his rivals, meanwhile, he had managed to sidestep the obvious resemblances between his Massachusetts health care bill and the White House’s Affordable Care Act. And by selling himself as a turnaround artist rather than an ideologue, a champion of the middle class rather than a defender of his fellow 1 percenters, he seemed well-positioned to campaign on competence, experience and sound economic stewardship in the general election.

From the very first debates onward, Romney has spent the primary campaign walking a fine line — trying to assuage widespread right-wing doubts about his ideological reliability, while crafting a persona and a policy portfolio that will appeal to moderates as well as conservatives come November.

the last thing an elite education will teach you is its own inadequacy

I’m talking about the whole system in which these skirmishes play out. Not just the Ivy League and its peer institutions, but also the mechanisms that get you there in the first place: the private and affluent public “feeder” schools, the ever-growing parastructure of tutors and test-prep courses and enrichment programs, the whole admissions frenzy and everything that leads up to and away from it. The message, as always, is the medium. Before, after, and around the elite college classroom, a constellation of values is ceaselessly inculcated.

The first disadvantage of an elite education, as I learned in my kitchen that day, is that it makes you incapable of talking to people who aren’t like you. Elite schools pride themselves on their diversity, but that diversity is almost entirely a matter of ethnicity and race. With respect to class, these schools are largely—indeed increasingly—homogeneous. Visit any elite campus in our great nation and you can thrill to the heartwarming spectacle of the children of white businesspeople and professionals studying and playing alongside the children of black, Asian, and Latino businesspeople and professionals.

these findings suggest that the neurophysiological mechanisms that we employ while dreaming (and recalling dreams) are the same as when we construct and retrieve memories while we are awake.

the researchers found that vivid, bizarre and emotionally intense dreams (the dreams that people usually remember) are linked to parts of the amygdala and hippocampus. While the amygdala plays a primary role in the processing and memory of emotional reactions, the hippocampus has been implicated in important memory functions, such as the consolidation of information from short-term to long-term memory.

it was not until a few years ago that a patient reported to have lost her ability to dream while having virtually no other permanent neurological symptoms. The patient suffered a lesion in a part of the brain known as the right inferior lingual gyrus (located in the visual cortex). Thus, we know that dreams are generated in, or transmitted through this particular area of the brain, which is associated with visual processing, emotion and visual memories.

Turning a blind eye. Giving someone the cold shoulder. Looking down on people. Seeing right through them. These metaphors for condescending or dismissive behavior are more than just descriptive. They suggest, to a surprisingly accurate extent, the social distance between those with greater power and those with less

A growing body of recent research shows that people with the most social power pay scant attention to those with little such power. This tuning out has been observed, for instance, with strangers in a mere five-minute get-acquainted session, where the more powerful person shows fewer signals of paying attention, like nodding or laughing. Higher-status people are also more likely to express disregard, through facial expressions, and are more likely to take over the conversation and interrupt or look past the other speaker.

A prerequisite to empathy is simply paying attention to the person in pain. In 2008, social psychologists from the University of Amsterdam and the University of California, Berkeley, studied pairs of strangers telling one another about difficulties they had been through, like a divorce or death of a loved one. The researchers found that the differential expressed itself in the playing down of suffering. The more powerful were less compassionate toward the hardships described by the less powerful.

The popular left/right story has no solid basis in science. The brain doesn't work one part at a time, but rather as a single interactive system, with all parts contributing in concert, as neuroscientists have long known. The left brain/right brain story may be the mother of all urban legends: It sounds good and seems to make sense—but just isn't true.

There is a better way to understand the functioning of the brain, based on another, ordinarily overlooked anatomical division—between its top and bottom parts. We call this approach "the theory of cognitive modes." Built on decades of unimpeachable research that has largely remained inside scientific circles, it offers a new way of viewing thought and behavior

Our theory has emerged from the field of neuropsychology, the study of higher cognitive functioning—thoughts, wishes, hopes, desires and all other aspects of mental life. Higher cognitive functioning is seated in the cerebral cortex, the rind-like outer layer of the brain that consists of four lobes
