I’ve stopped being sorry for all my soft. I won’t apologize because I miss you, or because I said it, or because I text you first, or again. I think everyone spends too much time trying to close themselves off. I don’t want to be cool or indifferent, I want to be honest.

The researchers found that that sad music has a counterintuitive appeal – it actually makes people feel better. Sad songs allow listeners to experience indirectly the emotions expressed in the lyrics and implied by the (usually) minor-key melodies. The sadness may not directly reflect the listener’s own experiences, but it triggers chemicals in our brain that can produce a cathartic response: tears, chills, an elevated heartbeat. This is not an unpleasant feeling, and may explain why listeners are inclined to buy sad songs and why artists want to write or sing them.

Why does the brain remember dreams?

Some people recall a dream every morning, whereas others rarely recall one. A team led by Perrine Ruby, an Inserm Research Fellow at the Lyon Neuroscience Research Center (Inserm/CNRS/Université Claude Bernard Lyon 1), has studied the brain activity of these two types of dreamers in order to understand the differences between them. In a study published in the journal Neuropsychopharmacology, the researchers show that the temporo-parietal junction, an information-processing hub in the brain, is more active in high dream recallers. Increased activity in this brain region might facilitate attention orienting toward external stimuli and promote intrasleep wakefulness, thereby facilitating the encoding of dreams in memory.

Positive, negative thinkers’ brains revealed

The ability to stay positive when times get tough – and, conversely, of being negative – may be hardwired in the brain, finds new research led by a Michigan State University psychologist.

The study, which appears in the Journal of Abnormal Psychology, is the first to provide biological evidence validating the idea that there are, in fact, positive and negative people in the world.

“It’s the first time we’ve been able to find a brain marker that really distinguishes negative thinkers from positive thinkers,” said Jason Moser, lead investigator and assistant professor of psychology.

For the study, 71 female participants were shown graphic images and asked to put a positive spin on them while their brain activity was recorded. Participants were shown a masked man holding a knife to a woman’s throat, for example, and told one potential outcome was the woman breaking free and escaping.

The participants were surveyed beforehand to establish who tended to think positively and who thought negatively or worried. Sure enough, the brain reading of the positive thinkers was much less active than that of the worriers during the experiment.

“The worriers actually showed a paradoxical backfiring effect in their brains when asked to decrease their negative emotions,” Moser said. “This suggests they have a really hard time putting a positive spin on difficult situations and actually make their negative emotions worse even when they are asked to think positively.”

The study focused on women because they are twice as likely as men to suffer from anxiety related problems and previously reported sex differences in brain structure and function could have obscured the results.

Moser said the findings have implications in the way negative thinkers approach difficult situations.

“You can’t just tell your friend to think positively or to not worry – that’s probably not going to help them,” he said. “So you need to take another tack and perhaps ask them to think about the problem in a different way, to use different strategies.”

Negative thinkers could also practice thinking positively, although Moser suspects it would take a lot of time and effort to even start to make a difference.


Van der Waals helps geckoes scale walls

Face it, it would be totally cool if we could clamber up surfaces as easily as geckoes do. We could scale skyscrapers, never fear when climbing ladders, and could completely eliminate that tacky dramatic moment in movies where the hero dangles precariously over the street a hundred storeys below. Of course, their sweaty fingers would never slip if they had some kind of adhesion mechanism—they could just climb right back up.

So how do geckoes manage it?

Well, unlike humans, geckoes have millions of microscopic hairs on the bottom of their feet, called setae. The tips of each of these setae are split into 100-1000 spatulae, which are so small that they’re narrower than the wavelength of visible light—less than 300 nano metres.

Clearly, some kind of intermolecular force between the gecko’s feet and a surface is responsible for adhesion, but it wasn’t until research in 2002 that we fully understood what was going in—for a while, scientists were throwing around theories like suction and chemical bonding.

Turns out, geckoes take advantage of the Van der Waals force.

Named after a nineteenth century Dutch physicist, Van der Waals forces are weak electrodynamic forces that act over tiny distances, yet bond almost any material. They’re created by fluctuations in charge distributions between molecules.

These weak forces can be strengthened as more and more of one surface touches the other—like, say if you had billions of spatulae coating your feet. These tiny hairs increase surface density, so on contact with the wall the gecko experiences a strong adhesive force

Essentially, this force means we can improve adhesion simply by increasing surface density, like subdividing a surface into countless small protrusions. It means that geometry—not chemistry—is the driving mechanism. A single setae can lift an ant; a million could lift a 20 kg child; and if geckoes used every setae simultaneously, they could support 130 kg.

These forces open up to a lot of applications in adhesives. Engineers at Berkeley and Stanford have developed biologically inspired synthetic adhesives that adhere like gecko pads, which have even been used on robotic climbers.
