Bigwizzle, stupid or not?

It all started when a user named bigwizzle45 called someone else an idiot.

To which someone replied: Says the guy under the name of "bigwizzle"

To which bigwizzle replied: Are you implying I'm an idiot becaus of my user name?

From the utube discussion thread of the video Celebrate!, by Kool and the Gang.

Conversation thread found

K says: sounds like disturbed

T says: not even close to disturbed...this is like a soft 1 inch cock compared to the hardcore 12 inch black dick that is disturbed.

Z says: i asume u mean the old disturbed, the new disturbed sucks major hardcore! but sickness disturbed is more like a 20 inch somali dick that is going through your ears ass hole!

M says: they were better before but theyre still good now. dont noe why u think they suck. regardless, distubed in general is a rock hard black cock with throbbing veins leaking pre ejaculatory fluids ready to blast a load of jizz onto bands like these.

To which Z replies: the new shit SOUNDs like the old stuff music wise but the lyrics r rly panseyish. dont get me wrong i saw em live and it was a great show! but the new songs arnt very distrbing and they lack the sickness!!!!

Are Humans Still Evolving?

According to TIME,

Modern Homo sapiens is still evolving. Despite the long-held view that natural selection has ceased to affect humans because almost everybody now lives long enough to have children, a new study of a contemporary Massachusetts population offers evidence of evolution still in action.

A team of scientists led by Yale University evolutionary biologist Stephen Stearns suggests that if the natural selection of fitter traits is no longer driven by survival, perhaps it owes to differences in women's fertility.

But without survival to call the odds, what do you think nature selects?

The number one reason of reality meltdown

According to Wikipedia, "a cognitive bias is a pattern of deviation in judgment that occurs in particular situations... " or in other words nothing else but assumption. The entry goes on to explain a list of a hundred or so cognitive biases that may occur daily in our lives.

Take for instance the Bandwagon effect as it relates to twitter. This effect describes the tendency to do (or believe) things because many other people do (or believe) the same. According to Wikipedia it is related to groupthink and herd behaviour. Just like with many of the other bias found, this one has ingrained itself in our society such that it has given raise to the popular expression of "jumping the bandwagon".

They color every aspect of our reality and link each and every one of us almost inexplicably to a past that in many cases is not even our own. They are a big part of the reason why we are unbelievably bad in calculating odds and making planned choices, even against our own better judgment. And they are notoriously difficult to avoid, even by trained psychologists that know exactly how they influence or daily lives.

The best way to rid ourselves of these mind bending memes from our collective memory is to live fully in each moment. For many the proposition of facing the glare of reality without our bias colored shades may be scary at first, but most people find the experience exhilarating and fun. Exactly the way it should be.



How we deal with breavement and PTSD

According to New Scientist, research is focusing on what happens in our brain when someone close to us dies.
The bottom line of Bonanno, a clinical psychologist at Columbia University in New York is "that people are often much more resilient than we're led to believe". This is confirmed by studies of Londoners after the Blitz and New Yorkers after 9/11 which showed that few people suffer serious reactions to traumatic events.

This stands in contrast to the average of 8% of people that develop PTSD, which according to Wikipedia follow after events such as violent assault, kidnapping, sexual assault, torture, being a hostage, prisoner of war or concentration camp victim, experiencing a disaster, violent automobile accidents or getting a diagnosis of a life-threatening illness. Children may develop PTSD symptoms by experiencing bullying or sexually traumatic events like age-inappropriate sexual experiences.

All of which make me wonder if the experiences of people who find it difficult to cope with death may not be identical to those suffering of PTSD? In my own mind I ponder that the ability to "go on" is a common observation in people that cope well with bereavement and trauma.

In some people it is nothing but tenacity, in others you find it cast by tough determination, but in the scientific community it is called resilience. Resilience describes all the different reasons why some people can just stand up and dust themselves off and include the way in which the qualities combine to make a person more resilient. All, except one reason.

Just like guilt and forgiveness, resilience is a quality left moot by acceptance.  Just like forgiveness, acceptance is a choice that can only be made by yourself, although it helps if you've got faith. According to earlier research, experience with the earthquake victims in NWFP & AJK clearly demonstrated the positive effects of faith & resilience. The findings echo that of others who show how faith in God Almighty, or some sort of divine existence is a major factor in strengthening resilience and promoting recovery from traumatic stress disorders.

By acknowledging the "Hand of God" we allow ourselves to see the "Hand of God" in our lives. From this perspective we have only one choice, even in the face of trauma and bereavement. To "go on" in faith isn't difficult at all, it is the only choice there is.


The importance of now become trendy

Reporting on the trending issue of NOWISM -

According to Trendwatching - “Consumers’ ingrained" lust for instant gratification is being satisfied by a host of novel, important (offline and online) real-time products, services and experiences. Consumers are also feverishly contributing to the real-time content avalanche that’s building as we speak. As a result, expect your brand and company to have no choice but to finally mirror and join the ‘now’, in all its splendid chaos, realness and excitement.”

Godscience

According to an article in FaithWorld:

Until not too long ago, most people believed human morality was based on scripture, culture or reason. Some stressed only one of those sources, others mixed all three. None would have thought to include biology. With the progress of neuroscientific research in recent years, though, a growing number of psychologists, biologists and philosophers have begun to see the brain as the base of our moral views. Noble ideas such as compassion, altruism, empathy and trust, they say, are really evolutionary adaptations that are now fixed in our brains. Our moral rules are actually instinctive responses that we express in rational terms when we have to justify them.
(Photo: Religious activist at a California protest, 10 June 2005/Gene Blevins)

Thanks to a flurry of popular articles, scientists have joined the ranks of those seen to be qualified to speak about morality, according to anthropologist Mark Robinson, a Princeton Ph.D student who discussed this trend at the University of Pennsylvania’s Neuroscience Boot Camp. “In our current scientific society, where do people go to for the truth about human reality?” he asked. “It used to be you might read a philosophy paper or consult a theologian. But now there seems to be a common public sense that the authority over what morality is can be found by neuroscientists or scientists.”

This change has come over the past decade as brain scan images began to reveal which areas of the brain react when a person grapples with a moral problem. They showed activity not only in the prefrontal cortex, where much of our rational thought is processed, but also in areas known to handle emotion and conflicts between brain areas. Such insights cast doubt on long-standing assumptions about reason or religion driving our moral views. “A few theorists have even begun to claim that that the emotions are in fact in charge of the temple of morality and that moral reasoning is really just a servant masquerading as the high priest,” University of Virginia psychologist Jonathan Haidt, one of the leading theorists in this field, has written.

But according to Mark Robinson, "The question of authority is a big one. Who is the ultimate authority on these issues about the fundamental nature of human morality?”



The whole "human capacity to manipulate our environment" dilemma.

In a New Scientist book review of "Time" by Eva Hoffman they say"
Our societies have become obsessed with time and timekeeping, both in the workplace and at home. Jet travel manipulates our experience of day-night cycles and seasons, while biomedical science races to increase our lifespan yet further. At the other end of the spectrum, new technologies adapt our minds to the ever-briefer scales of micro and nano.

A recurring theme in the book is how the human capacity to manipulate our environment ushers in new complexities to the basic biology of time. For example, while other animals age and die on a strict schedule, humans do everything in their power to control that timing. And the book is full of interesting thoughts: consider the different temporal experience of wild blueberry bushes, which live 13,000 years, and mayflies, which fulfil their earthly purpose in a lifespan of hours.

Did someone say, "What!? I didn't know that?"?


Some googledygoop, coochie, coochie

If you keep on telling your friends, like neuroscientist Manuel Carrieras would have said, "Now isn't that the ideal opportunity for research into our brain?", then you will enjoy this!

After decades spent fighting, members of the guerrilla forces have begun re-integrating into mainstream Colombian society, introducing a sizeable population of illiterate adults who have no formal education. Upon putting down their weapons and returning to society, some had the opportunity to learn to read for the first time in their early twenties, providing the perfect natural situation for experiments investigating structural brain differences associated with the acquisition of literacy in the absence of other types of schooling or maturational development.

A neuroscientist by the name of Manuel Carrieras and his colleagues jumped at the opportunity and, according to Mind Hacks, they are glad they did!

"it is almost impossible to separate out which are the brain changes due specifically to acquiring literacy and which are just part of the massive changes that constantly take place as children develop..." But after the study we now know that even if literacy develops only during the adult years, the brain scans of the previous illiterates grow. Just as it does when we're babies.




'Bombing' of moon bad idea from start

More news from New Scientist about scientist's attempt to find water on the moon by smashing it with a rocket.
Weeks before NASA's LCROSS mission crashed into the moon, some scientists involved with the mission were predicting very little, if anything, would be seen from the impact – despite a well publicised observing campaign.

Others now say the $79 million mission was ill conceived and will not deliver a meaningful result even if it manages to find evidence for water on the moon.

LCROSS ended on Friday morning when a two-tonne Centaur rocket hit the floor of a perpetually shadowed crater near the lunar south pole.

The spirit of plants

It was in the early 1900’s, just after the discovery of the lie detector that we first became aware that plants are more than just compost, and that they seem to display some kind of prescience. As much as I guess by accident, but profound in its implication we found that somehow a plant knew who was going to harm it, and who was going to care for it. The finding that plants “knew” things that people intend never gained a big following, but that doesn’t change the fact that they do…

The curious case of altruism.

World Science suggests that

Giving among strangers more nurture than nature, study suggests
Al­tru­ism has long been a sub­ject of in­ter­est to sci­en­tists. Su­per­fi­cially at least, ev­o­lu­tion­ary the­o­ry sug­gests al­tru­ism should­n’t ex­ist. Ev­o­lu­tion oc­curs be­cause some genes in a popula­t­ion are usu­ally more ad­van­ta­geous than oth­ers. The fa­vor­a­ble genes spread through the popula­t­ion be­cause their bear­ers are able to out-reproduce oth­er in­di­vid­u­als, grad­u­ally chang­ing the whole group’s char­ac­ter­is­tics. This does­n’t seem to al­low for al­tru­ism, as pre­sumably only those who help them­selves ul­ti­mately get ahead in the ev­o­lu­tion­ary race.

Now I wonder how that would work with apes? Oh wait, threy groom each other all the time, don't they ;-?


Out of body experiences

Astral travel is the focus of this article in NewScientist, and researchers says it's easy to do. Some people even like it!

Out of your head: Leaving the body behind - life - 13 October 2009 - New Scientist
So what exactly is an out-of-body experience? A definition has recently emerged that involves a set of increasingly bizarre perceptions. The least severe of these is a doppelgänger experience: you sense the presence of or see a person you know to be yourself, though you remain rooted in your own body. This often progresses to stage 2, where your sense of self moves back and forth between your real body and your doppelgänger. This was what Brugger's young patient experienced. Finally, your self leaves your body altogether and observes it from outside, often an elevated position such as the ceiling. "This split is the most striking feature of an out-of-body experience," says Olaf Blanke, a neurologist at the Swiss Federal Institute of Technology in Lausanne.
Surprisingly pleasant

Some out-of-body experiences involve just one of these stages; some all three, in progression. Bizarrely, many people who have one report it as a pleasant experience. So what could be going on in the brain to create such a seemingly impossible sensation?


Stunning practice in religion

Animals feel the pain of religious slaughter - science-in-society - 13 October 2009 - New Scientist
Brain signals have shown that calves do appear to feel pain when slaughtered according to Jewish and Muslim religious law, strengthening the case for adapting the practices to make them more humane.

The findings increase pressure on religious groups that practice slaughter without stunning to reconsider. "It provides further evidence, if it was needed, that slaughtering an animal without stunning it first is painful," says Christopher Wathes of the UK Farm Animal Welfare Council, which has long argued for the practice to end.Representatives for both faiths responded by claiming that stunning itself hurts animals.

A spokesman for Shechita UK says that the throat cut is so rapid that it serves as its own "stun", adding that there is abundant evidence shechita is humane.


Chimps lend a helping hand

According to the latest Newscientist -

Chimps happy to help – you just have to ask - life - 13 October 2009 - New Scientist
If you're looking for help from a chimp, don't forget to say please. Captive chimpanzees readily help others obtain an out-of-reach snack, but only if they beg for it, a new study shows.

Researchers have long debated whether chimpanzees act altruistically. In the wild, the great apes exchange grooming duties, and occasionally food such as meat, but whether these transactions fit the definition of altruism is controversial.

In dozens of trials involving six pairs of chimpanzees, one of the chimps consistently offered the tool to the other. But help often came only after the chimp in need reached out its hands or made a ruckus.Such requests may be necessary because chimpanzees don't fully understand the desires of others, Yamamoto says.

Currents that flow forever?

Physicists Measure Elusive 'Persistent Current' That Flows ForeverIt just goes to show, you are never too old to learn!

(PhysOrg.com) -- Physicists at Yale University have made the first definitive measurements of "persistent current," a small but perpetual electric current that flows naturally through tiny rings of metal wire even without an external power source.The counterintuitive current is the result of a quantum mechanical effect that influences how electrons travel through metals, and arises from the same kind of motion that allows the electrons inside an atom to orbit the nucleus forever. “These are ordinary, non-superconducting metal rings, which we typically think of as resistors,” Harris said. “Yet these currents will flow forever, even in the absence of an applied voltage.”

Crashing into the moon without success

On 09 October 2009, shortly after 4:31 am Pacific time (12:31 BST), a 2366 kilogram booster rocket named LCROSS crashed into a shadowed crater near the moon's south pole. The high speed collision was part of an experiment to determine if there is water on the moon - but contrary to expectations there was curiously little to see!
As hundreds of telescopes and observers watched, a NASA mission to search for water on the moon has achieved its grand finale with a pair of high-speed crashes into the lunar surface according to the article in New Scientist.

At the Ames Research Center near Palo Alto, California, scientists and engineers with the Lunar Crater Observation and Sensing Satellite (LCROSS) peered in silent concentration as successive images of the crater Cabeus grew larger on their screens. there was no telltale flash to be seen from the expected collision of a 2366-kilogram booster rocket into the permanently shadowed crater, located near the moon's south pole.

"I think we're all a little bit disappointed that we didn't see anything," David Morrison, director of NASA's Lunar Science Institute, told New Scientist. "But 90 per cent of the data has not yet been seen."


The problem with facial recognition...

One of the first cognitive abilities that we develop after birth is the ability to recognize faces, but according to a recent article in Scientific American we can still get confused by such basic qualities like sexuality under the right circumstances.

Read all about it in
What's in a face?
Our nervous systems are hardwired to detect and process faces rapidly and efficiently, oftentimes with very scarce details available. The pictures in the accompanying slide are often referred to as Mooney faces, after cognitive psychologist Craig Mooney, who used similar images in his research on perception. Mooney faces illustrate how little visual information it takes to “see” a face.

Productivity and Chinese Philosophy

In response to growing unrest by individuals in the open market system the company created benefits. Benefits that are targeted, not only on the individual, but on the family unit as a whole.

Socially, the Chinese Married Couple is thought to be the basic unit of society. It is therefore expected that a basic unit of society is the smallest productive unit of the economy, this according to Chinese philosophy. According to Western practice, the smallest productive unit in the economy is the individual.

While this may be a convenient way to ensure that the principle of payment and remuneration may be assured, and even though it provides for a carefully legislated environment it is of very little value to companies that also depend on the principle of fair work for fair pay. While it provides an excellent way for the legislated administration of basic economic rights, it places a lot of strain on any married couple that depend on that income to provide for the demands of an ever changing family unit.

It is also affirmation that perhaps Chinese philosophy may be better than Western practice.

Taste develops before birth

According to Alan Greene, a clinical professor of pediatrics at Stanford University and the author of the new Feeding Baby Green, children can acquire what he calls nutritional intelligence, which will help them choose healthy food later in life.
A fetus in the second and third trimester has highly sensitive taste buds that, through "practice meals" of amniotic fluid, get to experience whatever Mom is eating. Fetuses remember flavors from this time in the womb and seek them out after birth. This process explains why adopted infants, when swept off to a new culture, years later innately prefer their native cuisine — even though they may never have actually eaten it in the conventional sense, he says.

It makes me wonder what other sensory preferences we develop before birth?


Pro coke and pro racism

The late nineteenth century was a time when many of the turmoil that we struggle with today was born, and the Roman Catholic Church was as the center of most of it. According to one of the liberal thinkers of the age, Paolo Mantegazza:
On the use of coca:

Paolo Mantegazza also believed that drugs and certain foods would change humankind in the future, and defended the experimental investigation and use of cocaine as one of these miracle drugs (its addiction potential was not known at the time). When Mantegazza returned from South America, where he had witnessed the use of coca by the natives, he was able to chew a regular amount of coca leaves and then tested on himself in 1859. Afterwards, he wrote a paper titled Sulle Virtù Igieniche e Medicinali della Coca e sugli Alimenti Nervosi in Generale ("On the hygienic and medicinal properties of coca and on nervous nourishment in general"). He noted enthusiastically the powerful stimulating effect of cocaine in coca leaves on cognition:

"... I sneered at the poor mortals condemned to live in this valley of tears while I, carried on the wings of two leaves of coca, went flying through the spaces of 77,438 words, each more splendid than the one before...An hour later, I was sufficiently calm to write these words in a steady hand: God is unjust because he made man incapable of sustaining the effect of coca all life long. I would rather have a life span of ten years with coca than one of 10 000 000 000 000 000 000 000 centuries without coca."

On racial supremacy:

In a time when the popular and official science and culture in Italy were still under heavy influence of the Roman Catholic Church, Mantegazza was a staunch liberal and defended the ideas of Darwinism in anthropology, his research having helped to establish it as the "natural history of man". From 1868 to 1875 he maintained a correspondence with Charles Darwin, too. Mantegazza's natural history, however, must be considered to be from a racist/social Darwinist perspective, evident in his "Morphological Tree of Human Races." This tree maps three principles: a single European metanarrative marshals all of the world's many cultures; human history is imagined as progressive, with the European human as the pinnacle of progress and development; lastly, a ranking of different races onto a hierarchical structure. If one envisions a tree, the Aryan race is the topmost branch, followed by Polynesians, Semites, Japanese, and moving downward to the bottommost branch, the "Negritos." Mantegazza also designed an "Aesthetic Tree of the Human Race" with similar results.

Getting shot!

Carrying a gun increases risk of getting shot and killed - science-in-society - 06 October 2009 - New Scientist
Packing heat may backfire. People who carry guns are far likelier to get shot – and killed – than those who are unarmed, a study of shooting victims in Philadelphia, Pennsylvania, has found.

It would be impractical – not to say unethical – to randomly assign volunteers to carry a gun or not and see what happens. So Charles Branas's team at the University of Pennsylvania analysed 677 shootings over two-and-a-half years to discover whether victims were carrying at the time, and compared them to other Philly residents of similar age, sex and ethnicity. The team also accounted for other potentially confounding differences, such as the socioeconomic status of their neighbourhood.

Now this is good research!

Looking for facts

Looking up the AskOxford definition of the word fact it tells us the word is a noun meaning a thing that is indisputably the case. The word indisputable either means fact (huh?), or when it is used as an adjective it means unable to be challenged or denied.

And thus begin my search for the truth about reality, which according to the AskOxford tome is the state of things as they actually exist. The question that immediately pops up in my mind is how can we determine if something does indeed exist, but just as in the case of fact I wouldn't advise anyone to start with a definition.

According to AskOxford the word exist is a verb that means have objective reality or being. No wonder that the American essayist, philosopher and poet R.W. Emerson said that dictionaries are full of suggestion, the raw material of possible poems and histories?

And just as it is impossible to find any indisputable meaning to reality or existence, the same is true of truth, which is a noun that means a fact or belief that is accepted as true.

Thirst to cause ecologic change

India's thirst is making us all wet - environment - 03 October 2009 - New Scientist
ONE nation's thirst for groundwater is having an impact on global sea levels. Satellite measurements show that northern India is sucking some 54 trillion litres of water out of the ground every year. This is threatening a major water crisis and adding to global sea level rise.

According to the research could be pushing up global sea levels by as much as 0.16 millimetres each year. That's 5 per cent of total sea level rise, which may just be enough to change the whole ecology of the sea.

Have you ever!

Playing nice...

Better world: Be nice to people - science-in-society - 19 September 2009 - New Scientist
It sounds kind of obvious, and a little trite: the world would be a better place to live in if we were all a bit kinder to each other. But how can we make that happen?

This is fast becoming a valid scientific question. Psychologists and neuroscientists are exploring how to increase people's capacity for empathy and compassion, with two ongoing studies claiming that meditation not only increases compassionate feelings but also improves physical and emotional health.

But you don't have to be a Buddhist monk or an expert on brain plasticity to help increase global compassion. There is evidence that altruistic acts spread through social networks. In other words, if you are kind to a friend, they are more likely to be kind to someone else they know.


Feeling what we feel

Icy stares and dirty minds: Hitch-hiking emotions - life - 15 September 2009 - New Scientist
WILL these hands ne'er be clean?" asks Lady Macbeth, as she obsessively tries to wash away the guilt she feels for her role in the murder of King Duncan. Her feelings of self-disgust, we are led to believe, have manifested themselves as a sensation of physical dirtiness.

It is not only in the language of playwrights such as Shakespeare that complex emotions like guilt, grief or loneliness are compared to physical sensations. These metaphors crop up in everyday phrases, too, in many languages. In English, for example, we talk of being "left out in the cold" when we feel socially excluded, a sentiment echoed in the Japanese saying "one kind word can warm three winter months".

At face value, these connections seem purely symbolic. In real life, loneliness doesn't really send us shivering, and guilt doesn't really make us feel dirty. Or do they? Recent research has found that these physical sensations can often accompany our emotions. It works the other way too - by provoking a feeling of disgust, a scene from the film Trainspotting shaped the way subjects in an experiment made moral judgements.


Legalise it?

Better world: Legalise drugs - 11 September 2009 - New Scientist
Far from protecting us and our children, the war on drugs is making the world a much more dangerous place.

SO FAR this year, about 4000 people have died in Mexico's drugs war - a horrifying toll. If only a good fairy could wave a magic wand and make all illegal drugs disappear, the world would be a better place.

Dream on. Recreational drug use is as old as humanity, and has not been stopped by the most draconian laws. Given that drugs are here to stay, how do we limit the harm they do?

The evidence suggests most of the problems stem not from drugs themselves, but from the fact that they are illegal. The obvious answer, then, is to make them legal.

Quantum reality

Instant Expert: Quantum World - physics-math - 04 September 2006 - New Scientist
Entanglement is the idea that in the quantum world, objects are not independent if they have interacted with each other or come into being through the same process. They become linked, or entangled, such that changing one invariably affects the other, no matter how far apart they are - something Einstein called "spooky action at a distance".

Entanglement may also provide a nearly uncrackable method of communication. Quantum cryptographers can send "keys" to decode encrypted information using quantum particles. Any attempt to intercept the particles will disturb their quantum state - an interference that could then be detected.

In April 2004, Austrian financial institutions performed the first money transfer encrypted by quantum keys, and in June, the first encrypted computer network with more than two nodes was set up across 10 kilometres in Cambridge, Massachusetts, US. 

Quantum computers are another long-term goal. Because quantum particles can exist in multiple states at the same time, they could be used to carry out many calculations at once, factoring a 300-digit number in just seconds compared to the years required by conventional computers.

But particles of matter interact so easily with others that their quantum states are preserved for very short times - just billionths of a second. Photons, on the other hand, maintain their states about a million times longer because they are less prone to interact with each other. But they are also hard to store, as they travel, literally, at the speed of light.

In 2001, scientists managed to stop light in its tracks, overcoming one practical hurdle. And the first quantum logic gate - the brains behind quantum computers - was created with light in 2003.



The wonder of water

And the amazing story of water continues...

Spinning water droplets behave like black holes - physics-math - 15 December 2008 - New Scientist
WHAT does a drop of water have in common with a black hole and an atom? Well, levitating water droplets can now simulate the dynamics of both cosmological and subatomic objects.

"The breakthrough in this work is the ability to reproduce, in a simple table-top experiment, 100 years of theoretical work in fluid dynamics," says Vitor Cardoso of the University of Mississippi.


The wonders of water

When opposite charges repel - physics-math - 17 September 2009 - New Scientist
OPPOSITES always attract, right? Not quite. A new experiment has shown that a drop of water with positive electrical charge can be made to "bounce off" a negatively charged object.

William Ristenpart of the University of California at Davis accidentally applied a strong electric field to a beaker filled with oil and water. At first the mixture erupted into a turbulent mess, but as he turned down the voltage Ristenpart saw droplets of waterMovie Camera suspended in the oil bouncing between the electrode at the top of the beaker and the oil-water boundary below. The droplets were positively charged, so why didn't they merge with the negatively charged body of water?

Ristenpart thinks that positive ions drain out of the droplet and
negative electrons come in through the bridge, so the droplet, now
negatively charged, is drawn up to the positive electrode, where it
regains its original positive charge, and so on.

Take Off Friday

Better world: Take Friday off… forever - 15 September 2009 - New Scientist
Not everyone will like the idea of working longer days or taking a pay cut in exchange for a 3-day weekend, but it appears most do. Rex Facer at Brigham Young University in Provo, Utah, questioned 151 human resources directors working for large cities across the US. Where city employees had been offered flexitime or 4/10 regimes, 64 per cent said the alternative work schedule improved morale, and 41 per cent said it improved productivity - though 9 per cent said the opposite.

“Cog­ni­tive tasks, as well as emo­tion­al tasks such as reg­u­lat­ing your emo­tions, can de­plete your self-reg­u­la­tory ca­pacity to ex­er­cise,” said Kath­leen Mar­tin Gi­nis of Mc­Mas­ter Un­ivers­ity in On­tar­i­o, lead au­thor of the stu­dy. “You only have so much will­pow­er.”


Subliminal's must be bad

Key to subliminal messaging: keep it negative, study suggests
Sub­lim­i­nal mes­sag­ing is most ef­fec­tive when the mes­sage be­ing con­veyed is neg­a­tive, ac­cord­ing to new re­search.

Sub­lim­i­nal im­ages – that is, im­ages shown so briefly that a view­er does­n’t con­sciously no­tice them – have long been the sub­ject of con­tro­ver­sy, par­tic­u­larly in the ad­ver­tis­ing field. Stud­ies have hinted that peo­ple can un­con­sciously pick up on sub­lim­i­nal in­forma­t­ion in­tend­ed to pro­voke an emo­tion­al re­sponse, but lim­ita­t­ions in the de­signs of the stud­ies have meant that the con­clu­sions weren’t con­sid­ered de­fin­i­tive.

A new study by Nilli Lavie of Un­ivers­ity Col­lege Lon­don and col­leagues, in­di­cates that peo­ple can pro­cess emo­tion­al in­forma­t­ion from sub­lim­i­nal im­ages and that in­forma­t­ion of “neg­a­tive val­ue” is bet­ter de­tected than in­forma­t­ion of “pos­i­tive val­ue.”


Immortality predicted

According to the American inventor and futurist Ray Kurzweil believe that in around 20 years we will have the means to reprogramme our bodies' stone-age software so we can halt, and then reverse, ageing.

"Ultimately, nanobots will replace blood cells and do their work thousands of times more effectively. Within 25 years we will be able to do an Olympic sprint for 15 minutes without taking a breath, or go scuba-diving for four hours without oxygen. Nanotechnology will extend our mental capacities to such an extent we will be able to write books within minutes. Heart-attack victims – who haven't taken advantage of widely available bionic hearts – will calmly drive to the doctors for a minor operation as their blood bots keep them alive."

Benefits of love

Love has inspired countless works of art, from immortal plays such as Romeo and Juliet, to architectural masterpieces such as the Taj Mahal, to classic pop songs, like Queen's “Love of My Life”. This raises the obvious question: why is love such a stimulating emotion? Why does the act of falling in love – or at least thinking about love – lead to such a spur of creative productivity?

One possibility is that when we’re in love we actually think differently. This romantic hypothesis was recently tested by the psychologists Jens Förster, Kai Epstude, and Amina Özelsel at the University of Amsterdam. The researchers found that love really does alter our thoughts, and that this profound emotion affects us in a way that is different than simply thinking about sex.

The clever experiments demonstrated that love makes us think differently in that it triggers global processing, which in turn promotes creative thinking and interferes with analytic thinking. Thinking about sex, however, has the opposite effect: it triggers local processing, which in turn promotes analytic thinking and interferes with creativity.
