In January, the shooting of Gabrielle Giffords produced a half dozen bona fide heroes, including Patricia Maisch, a 61-year-old woman who snatched ammunition out of alleged gunman Jared Loughner’s hands as he tried to reload. For good reason, people like these earn our respect and adulation; their grace under pressure strikes us as almost superhuman. Yet as we marvel at their deeds, we’re always left wondering about where, exactly, this composure comes from. Do these people emerge from the womb with sanguine looks on their faces, ready to perform life-saving surgery in the next room if necessary? Or is their coolness something they picked up through life experience? (…)

Let’s start with the “nature” side of the equation. For every one of us, the starting point for cool-headedness comes bundled within our DNA: our innate disposition toward anxiety. It’s never been a secret that anxiousness is partially inherited, but no one knew how much influence our genes threw around until psychiatrist Kenneth Kendler came along. In a 2001 study, Kendler and his colleagues examined 1,200 pairs of male twins, some identical and some fraternal, probing into each brother’s individual phobias. Because all of the twins shared the same upbringing, yet only the identical twins shared the same DNA, Kendler could filter out environmental factors altogether and calculate a pure figure for our genetic susceptibility to anxiety. The answer? Genes account for around 30 percent of our anxiousness.

We are now looking at a situation where electronic communication is with us at all times and the boundaries between internet and real life communication are becoming increasingly blurred. (…)

Facebook users have a mixture of what would be termed as weak ties (friends a user has a marginal link to), and close ties (friends with whom they maintain a close relationship) in one place. Developing weak ties is one of the primary sources for people using Facebook. Romantic relationships may only represent a small part of a person’s Facebook usage it is nevertheless the most public place a couple will represent themselves. Muize found there was a correlation between the time a user spends on Facebook and relationship jealousy, while Boyd and Lewis showed Facebook to be an environment that can impact upon an intimate relationship.

Much of the literature, however, has focused on the value of maintaining weak ties and enhancing social capital. This paper will take a different stance and compare how certain rituals on Facebook can impact a person’s intimate relationships on the offline environment.

Many a beer drinker will have puzzled over the following: why, when a can of beer is opened, do carbon dioxide bubbles form so slowly. Why not all at once?

The study of bubble formation in carbonated drinks is a relatively new science. In fact, it is only ten years since scientists settled this matter. One group calculated from first principles the rate at which carbon dioxide leaks from solution into a bubble. The answer is slowly. What’s more, it cannot start without some sort of nucleation site.

Then, another group discovered that the primary sources of nucleation are pockets of gas trapped in cellulose fibres in the drink. The news was greeted by the sound of clinking glasses the world over. Problem solved?

Not quite. While most beers and lagers are pressurised with carbon dioxide, some stouts, dark beers such as Guinness, are pressurised by a mixture of carbon dioxide and nitrogen.

They do this because nitrogen forms smaller bubbles giving the drink a smoother, creamier mouth feel. But it also changes the bubble dynamics significantly. The question is why.

In this article we provide a number of reasons for thinking that it is both wrong and unwise to procreate.

Humans are the most destructive creatures on the planet. We cause vast numbers of animal deaths (both directly and indirectly). We destroy habitats. We damage the environment. We are currently heating up the world’s climate in a way that is likely to be detrimental to countless numbers of animals (ourselves included). And we have the means, nuclear weapons, to destroy everything at the push of a button. (…)

The best way to stop the destruction is to remove the destructive force; to remove humans by refraining from procreation. In short, the colossal amount of harm caused by humans gives us a moral reason to boycott the human species. (…)

To procreate is to take an unjustifiable gamble that future generations will behave responsibly (more responsibly than us).

It should be so easy: Buy toothpaste. But few shopping trips are more bewildering.

An explosion of specialized pastes and gels brag about their powers to whiten teeth, reduce plaque, curb sensitivity and fight gingivitis, sometimes all at the same time. Add in all the flavors and sizes, plus ever-rising prices, and the simple errand turns into sensory overload.

Manufacturers acknowledge the problem and are putting the brakes on new-product introductions. Last year, 69 new toothpastes hit store shelves, down from 102 in 2007. (…)

Stores are trying to simplify, too. Last month, 352 distinct types or sizes of toothpaste were sold at retail, down from 412 in March 2008. (…)

With some 93% of U.S. adults using toothpaste, according to Mintel, there’s little room to recruit new users.

Even through the recession, when unit sales of toothpaste actually dipped, prices kept rising. The average price of toothpaste last year reached $2.83, up 8% over the past four years.

We modify our own opinions in line with what other people think, especially our friends and peers.

A problem for psychologists investigating the effect of peer influence is that it can be tricky to tell whether people are simply acquiescing in public, for show, or if their attitudes really have changed.

A new study by a team of psychologists at Harvard University has used an innovative mix of behavioural and brain-scan methods to show that peer influence really can change how people value something, in this case the attractiveness of a face.

Among the findings of a sweeping federal government survey of American sexual behavior is one that may surprise those bewailing a permissive and eros-soaked popular culture: More than one-quarter of people interviewed in their late teens and early 20s had never had sex. (…)

The uptick in abstinence is one of many revealing facts arising from structured interviews with a random sample of 13,495 Americans, ages 15 to 44, that were done from 2006 to 2008. The findings provide evidence for almost every theory and supposition about the nation’s secret sex life.

The survey results, released Thursday, suggest that oral sex may be a gateway to vaginal sex but that for some teens it is a stopping point. Most adults are monogamous. About 4 in 10 adults have had anal sex. Women are more likely than men to have same-sex liaisons. Or at least are more comfortable talking about them.

“The dinner went well. The guest of honor didn’t sneeze. We were lucky.”

This comment was heard after a dinner at the U.S. State Department, where senior administration officials hosted a dinner for a delegation beginning a week of high-level meetings. The guest that didn’t sneeze was the senior person, allergic to flowers. Even though there were flowers on the tables, there were no sneezes.

It wasn’t luck that the guest was comfortable. Research by the protocol staff had discovered the allergy and found flowers that wouldn’t cause a problem. Thanks to the staff’s work, no headlines appeared announcing that dinner at the Department of State made a visiting dignitary sick.

At first, reading this story seems to confirm the stereotype that protocol and the work of protocol officers is simply about flowers, menus and seating plans. But to focus on those tasks is to miss the purpose that drives these activities. Robert W. Frye, former Chief of Protocol (…) explained it clearly: “protocol is the art of creating a distraction-free environment that facilitates the complete and open exchange of information to resolve issues and build relationships in global business and international diplomacy.”

David Lane takes great pains to point out that randomness is only one aspect of Darwinism; natural selection, what Jacques Monod (1972) called “necessity”, seems to ensure that evolution has, if no purpose, at least some kind of direction. But if it has a direction, where is it going?

If survival of the fittest is not a tautology, as some critics have claimed (Wilkins 1997), shouldn’t evolution to some extent be predictable? Using evolutionary theory, we can look back into the past and understand how and why certain forms of life evolved. But what can we say about the future?

We need to address this question not simply to reassure people that life is more than just a matter of chance. Predictability goes to the heart of what science is and does. Science can be succinctly defined as the attempt to identify the causes of phenomena. But the process does not stop there. When we think we know what causes a phenomenon, we attempt to use this knowledge to predict other phenomena, and ultimately, by causing them by our own actions.

Blue whales can weigh over a thousand times more than a human being. That’s a lot of extra cells, and as those cells grow and divide, there’s a small chance that each one will mutate. A mutation can be harmless, or it can be the first step towards cancer. As the descendants of a precancerous cell continue to divide, they run a risk of taking a further step towards a full-blown tumor. To some extent, cancer is a lottery, and a 100-foot blue whale has a lot more tickets than we do.

Aleah Caulin of the University of Pennsylvania and Carlo Maley of the University of California, San Francisco, have done some calculations of the risk of cancer for blue whales thanks to their huge size. We don’t know a lot about cancer in blue whales, because blue whale oncology wards would be a wee bit awkward for everyone involved. So Caulin and Maley extrapolated up from humans.

About thirty percent of all people will get cancer by the end of their life. (…)

Blue whales do get cancer, but it’s hard to believe that they get it at the rates that come out of Caulin and Maley’s calculations. Blue whales are known to live well over a century. Bowhead whales have reached at least 211 years. If blue whales really did get cancer as fast as the models would suggest, they ought to be extinct.

The failure of the model means that blue whales must have some secrets for fighting cancer. (…)

The mere existence of whales is the most glaring example of what biologists call Peto’s Paradox. There seems to be no correlation between body size and cancer rates among animal species. We run a thirty percent risk of getting cancer over our life time. So do mice, despite the fact that they’re 1000 times smaller than we are.

People with full bladders make better decisions.

Researchers discovered the brain’s self-control mechanism provides restraint in all areas at once. They found people with a full bladder were able to better control and “hold off” making important, or expensive, decisions, leading to better judgement. (…)

Dr Mirjam Tuk, who led the study, said that the brain’s “control signals” were not task specific but result in an “unintentional increase” in control over other tasks.

“People are more able to control their impulses for short term pleasures and choose more often an option which is more beneficial in the long run,” she said. (…)

They concluded that people with full bladders were better at holding out for the larger rewards later.

A Gömböc (pronounced [ˈɡømbøts], simplified to Gomboc) is a convex three-dimensional homogeneous body which, when resting on a flat surface, has just one stable and one unstable point of equilibrium. Its existence was conjectured by Russian mathematician Vladimir Arnold in 1995 and proven in 2006 by Hungarian scientists Gábor Domokos and Péter Várkonyi. (…)

The balancing properties of the Gömböc are associated with the “righting response”, their ability to turn back when placed upside down, of shelled animals such as turtles and beetles.
