I write as I await the birth of my second son. If trends about fatherhood continue as they have over the last several decades, the chances are that he will have children in his 40s, and (some of) my grandchildren will be in their 40s or 50s in the year 2112. What sort of world will they inhabit? (…)

The last century has been the age of political rights. Never in our history have so many people taken part in choosing their leaders and having a say in how their societies are governed. To be sure, this unparalleled expansion of civil and political rights remains incomplete. Yet it is profoundly significant, not only due to its transformative impact on the lives of billions, but also because so many other phenomena in recent history are connected to it. The rights revolution is intertwined with diverse trends such as the development of technology; sustained yet uneven economic growth; a general decline in war within recent decades; and a population explosion placing new pressures on our resources and environment.

In this essay I will first outline the 10 most important trends, starting with the rights revolution itself, that have defined our economic, social, and political lives over the last 100 years. Then I will discuss how the rights revolution has helped shape the other nine trends.

Happiness has long been regarded as one of the highest goals in human life. If our sense of happiness is closely connected to brain functions, future methods may allow us to control happiness through refined, effective brain manipulation. Can we regard such happiness as true happiness? In this paper I will make some remarks on the manipulation of the sense of happiness and illuminate the relationship between human dignity and happiness. (…)

The President’s Council on Bioethics’s 2003 report Beyond Therapy includes an extensive discussion of the morality of mood-improvement drugs such as SSRIs (Selective Serotonin Reuptake Inhibitors). The report argues that while SSRIs can help patients live a better life by inducing calm, providing a background of well-being, and changing personality, such drugs create some fundamental ethical problems. First, one might come to “feel happy for no good reason at all, or happy even when there remains much in one’s life to be truly unhappy about.” Second, “SSRIs may generally dull our capacity to feel [psychic pain], rendering us less capable of experiencing and learning from misfortune or tragedy or empathizing with the miseries of others.” And third, those drugs “might shrink our capacity for true human flourishing.” To conclude, the report recommends those drugs be “sparingly” used so that we “are able to feel joy at joyous events and sadness at sad ones.”

The Council’s argument was made from the perspective of conservative or communitarian ethics, and it has been harshly criticized by proponents of technological advances as being overly sentimental. (…)

In order to further develop their argument, here I would like to make a thought experiment. Suppose we have a perfect happiness drug without any side effects, and, having taken that drug, the user is filled with a sense of happiness for a couple of days regardless of his or her experiences. (…) “Today my child was killed, but how happy I am now!” (…) This is a typical example of Beyond Therapy’s case in which a person feels “happy when there remains much in one’s life to be truly unhappy about.”

Why should we deal with pornography from a feminist perspective? The answer to this question is straightforward. Pornography is the key mass media genre in which sexuality is made visible and performed. Sexuality, on the other hand, is one of the main areas where gender and gender relations are negotiated. In this article, I will examine different – and in particular conflicting – feminist positions with respect to pornography which have been developed from the 1970s until today. The focus will be on the issue of the construction of sexual and gender identities. I will analyze how these identities in regards to the pornographic body are negotiated or even shifted within these different feminist discourses and practices. Dildos and cyborgs will be discussed in the final part of this article, which deals with current queer-feminist debates in the field of so called post-porn.

At the beginning of the seventies, in a phase of almost complete legalization of pornography in most of the western countries, the pornographic movie left the underground and was allowed into new public spheres. Pornography as a film genre developed into a mass product and was increasingly available even in cinemas. It was during that period that the sexual revolution came to an end, or rather began to transform itself into something new.

Waking up from surgery can be disorienting. One minute you’re in an operating room counting backwards from 10, the next you’re in the recovery ward sans appendix, tonsils, or wisdom teeth. And unlike getting up from a good night’s sleep, where you know that you’ve been out for hours, waking from anesthesia feels like hardly any time has passed. Now, thanks to the humble honeybee, scientists are starting to understand this sense of time loss. New research shows that general anesthetics disrupt the social insect’s circadian rhythm, or internal clock, delaying the onset of timed behaviors such as foraging and mucking up their sense of direction. (…)

Warman says his team is currently looking at whether shining bright light at someone under anesthesia—a well known way to alter the circadian clock—could also reduce the procedure’s disorienting effects.

In psychology, this phenomenon is called “gaslighting,” a term that has its origins in a 1938 play (and a 1940 film) called Gas Light, where a man leads his wife to believe that she is insane in order to steal from her. (…)

A classic example of psychological gaslighting is the following: Spouse A has an extramarital affair and tries to cover it up. Spouse B finds a suspicious text message in A’s phone and expresses concern to A. A then accuses B of being paranoid, and this pattern repeats every time B raises concerns. Eventually B begins to question his or her own perceptions.

For several years now, the Fed has been making money available to the financial sector at near-zero interest rates. Big banks and hedge funds, among others, have taken this cheap money and invested it in securities with high yields. This type of profit-making, called the “carry trade,” has been enormously profitable for them. (…)

Under my plan, each American household could borrow $10 million from the Fed at zero interest. The more conservative among us can take that money and buy 10-year Treasury bonds. At the current 2 percent annual interest rate, we can pocket a nice $200,000 a year to live on. The more adventuresome can buy 10-year Greek debt at 21 percent, for an annual income of $2.1 million. Or if Greece is a little too risky for you, go with Portugal, at about 12 percent, or $1.2 million dollars a year. (No sense in getting greedy.) (…)

Because we will be making money in basically the same way as hedge fund managers, we should have to pay only 15 percent in taxes, just like they do.

Baboons have mastered one of the basic elements of reading - identifying the difference between sequences of letters that make up actual words from nonsense sequences.

Although the animals have no linguistic skills, they were able to classify a four-letter sequence as either a real word or a random sequence. These findings challenge the long-held notion that the ability to recognise words in this way - as combinations of objects that appear visually in certain sequences - is fundamentally related to language.

It now appears that when humans read, we are partly drawing on an ancient ability, predating the evolution of our own species.

Linguists agree that language is needed during reading, but at which stage language becomes a necessity has come under debate. Past research has shown that animals have the ability to discriminate letters from one another, but previously experts thought the ability to recognise words was dependent on an ability to understand language.

In my new book Drop Dead Healthy, I try to become the healthiest person alive. In doing so, I examine hundreds of activities to determine if they are healthy.

Is meditation healthy? Yes. Petting dogs? Yes, because it lowers the blood pressure. Sitting? Definitely not. Going to a noisy restaurant? No. Taking naps? Thank God yes.

One of the few activities I didn’t discuss: Reading. Is reading healthy? Or will it slowly murder you?

No doubt I’m a bit biased, but I’ve come to the conclusion that overall, books are, in fact, good for your health. (…)

More and more research shows that sitting is bad for you. It significantly increases your chances of heart disease and slows your metabolism.

This is why, for my book, I ignored the siren call of my chair and did a lot of reading standing up. Reading on your feet burns about 34 more calories per hour than reading while sitting. Eventually, I took it further. I bought a treadmill, converted it into a desk, and did all my reading and writing while walking. It took me about a thousand miles to write the book.

According to what some call the strong definition of free will, articulated by René Descartes in the 17th century, you are free if, under identical circumstances, you could have acted otherwise. Identical circumstances refer to not only the same external conditions but also the same brain states. (…)

Contrast this strong notion of freedom with a more pragmatic conception called compatibilism, the dominant view in biological, psychological, legal and medical circles. You are free if you can follow your own desires and preferences. A long-term smoker who wants to quit but who lights up again and again is not free. His desire is thwarted by his addiction. Under this definition, few of us are completely free. (…)

Consider an experiment that ends with a 90 percent chance of an electron being here and a 10 percent chance of it being over there. If the experiment were repeated 1,000 times, on about 900 trials, give or take a few, the electron would be here; otherwise, it would be over there. Yet this statistical outcome does not ordain where the electron will be on the next trial. Albert Einstein could never reconcile himself to this random aspect of nature. (…)

This experiment was conceived and carried out in the early 1980s by Benjamin Libet, a neuropsychologist at the University of California, San Francisco. (…)

Intuitively, the sequence of events that leads to a voluntary act must be as follows: You decide to raise your hand; your brain communicates that intention to the neurons responsible for planning and executing hand movements; and those neurons relay the appropriate commands to the motor neurons that contract the arm muscles. But Libet was not convinced. Wasn’t it more likely that the mind and the brain acted simultaneously or even that the brain acted before the mind did?

Libet set out to determine the timing of a mental event, a person’s deliberate decision, and to compare that with the timing of a physical event, the onset of the readiness potential after that decision. (…)

The results told an unambiguous story, which was bolstered by later experiments. The beginning of the readiness potential precedes the conscious decision to move by at least half a second and often by much longer. The brain acts before the mind decides! This discovery was a complete reversal of the deeply held intuition of mental causation.

New scientific research raises the possibility that advanced versions of T. rex and other dinosaurs — monstrous creatures with the intelligence and cunning of humans — may be the life forms that evolved on other planets in the universe. “We would be better off not meeting them,” concludes the study, which appears in the Journal of the American Chemical Society. (…)

“An implication from this work is that elsewhere in the universe there could be life forms based on D-amino acids and L-sugars. Such life forms could well be advanced versions of dinosaurs, if mammals did not have the good fortune to have the dinosaurs wiped out by an asteroidal collision, as on Earth.”

Natural selection never favors excess; if a lower-cost solution is present, it is selected for. Intelligence is a hugely costly trait. The human brain is responsible for 25 per cent of total glucose use, 20 per cent of oxygen use and 15 per cent of our total cardiac output, although making up only 2 per cent of our total body weight. Explaining the evolution of such a costly trait has been a long-standing goal in evolutionary biology, leading to a rich array of explanatory hypotheses, ranging from evasion of predators to intelligence acting as an adaptation for the evolution of culture. Among the proposed explanations, arguably the most influential has been the “social intelligence hypothesis,” which posits that it is the varied demands of social interactions that have led to advanced intelligence.

Physicist: Alright, the Earth has only one mechanism for releasing heat to space, and that’s via (infrared) radiation. We understand the phenomenon perfectly well, and can predict the surface temperature of the planet as a function of how much energy the human race produces. The upshot is that at a 2.3% growth rate (conveniently chosen to represent a 10× increase every century), we would reach boiling temperature in about 400 years. And this statement is independent of technology. Even if we don’t have a name for the energy source yet, as long as it obeys thermodynamics, we cook ourselves with perpetual energy increase. (…)

Economist: Consider virtualization. Imagine that in the future, we could all own virtual mansions and have our every need satisfied: all by stimulative neurological trickery. We would stil need nutrition, but the energy required to experience a high-energy lifestyle would be relatively minor. This is an example of enabling technology that obviates the need to engage in energy-intensive activities. Want to spend the weekend in Paris? You can do it without getting out of your chair.

Physicist: I see. But this is still a finite expenditure of energy per person. Not only does it take energy to feed the person (today at a rate of 10 kilocalories of energy input per kilocalorie eaten, no less), but the virtual environment probably also requires a supercomputer—by today’s standards—for every virtual voyager. The supercomputer at UCSD consumes something like 5 MW of power. Granted, we can expect improvement on this end, but today’s supercomputer eats 50,000 times as much as a person does, so there is a big gulf to cross.

One by one, pillars of classical logic have fallen by the wayside as science progressed in the 20th century, from Einstein’s realization that measurements of space and time were not absolute but observer-dependent, to quantum mechanics, which not only put fundamental limits on what we can empirically know but also demonstrated that elementary particles and the atoms they form are doing a million seemingly impossible things at once. (…)

Eighty-seven years ago, as far as we knew, the universe consisted of a single galaxy, our Milky Way, surrounded by an eternal, static, empty void. Now we know that there are more than 100 billion galaxies in the observable universe. (…)

Combining the ideas of general relativity and quantum mechanics, we can understand how it is possible that the entire universe, matter, radiation and even space itself could arise spontaneously out of nothing, without explicit divine intervention. (…)

Perhaps most remarkable of all, not only is it now plausible, in a scientific sense, that our universe came from nothing, if we ask what properties a universe created from nothing would have, it appears that these properties resemble precisely the universe we live in.

We show that the number of gods in a universe must equal the Euler characteristics of its underlying manifold. By incorporating the classical cosmological argument for creation, this result builds a bridge between theology and physics and makes theism a testable hypothesis. Theological implications are profound since the theorem gives us new insights in the topological structure of heavens and hells. Recent astronomical observations can not reject theism, but data are slightly in favor of atheism.

Six studies demonstrate the “pot calling the kettle black” phenomenon whereby people are guilty of the very fault they identify in others. Recalling an undeniable ethical failure, people experience ethical dissonance between their moral values and their behavioral misconduct. Our findings indicate that to reduce ethical dissonance, individuals use a double-distancing mechanism. Using an overcompensating ethical code, they judge others more harshly and present themselves as more virtuous and ethical.

Computer scientists have analysed thousands of memorable movie quotes to work out why we remember certain phrases and not others. (…)

They then asked individuals who had not seen the films to guess which of the two lines was the memorable one. On average, people chose correctly about 75 per cent of the time, confirming the idea that the memorable features are inherent in the lines themselves and not the result of some other factor, such as the length of the lines or their location in the film. (…)

They then compared the memorable phrases with a standard corpus of common language phrases taken from 1967, making it unlikely to contain phrases from modern films. (…)

The phrases themselves turn out to be significantly distinctive, meaning they’re made up of combinations of words that are unlikely to appear in the corpus. By contrast, memorable phrases tend to use very ordinary grammatical structures that are highly likely to turn up in the corpus.
