How Organisms Evolve New Functions (Theory and Research)


"Evolution in Four Dimensions", trace four 'dimensions' in evolution: 
* Genetic
Epigenetic (or non-DNA cellular transmission of traits)
Behavioral 
Symbolic (transmission through language and other forms of symbolic communication). 

Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. These systems, they argue, can all provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution.

A team of researchers has documented the step-by-step process in which an organisms evolve new functions. The research decodes how E. colibacteria supplement a traditional diet of glucose with an extra course of citrate.




The 1st stage was potentiation, when the E. coli accumulated at least two mutations that set the stage for later events. The 2nd step, actualization, is when the bacteria first began eating citrate, but only just barely nibbling at it. The 3rd final stage, refinement, involved mutations that greatly improved the initially weak function. This allowed the citrate eaters to wolf down their new food source and to become dominant in the population.

New World Record for Solar Cell Efficiency

Jan. 18, 2013 — In a remarkable feat, scientists at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have developed thin film solar cells on flexible polymer foils with a new record efficiency of 20.4% for converting sunlight into electricity. The cells are based on CIGS semiconducting material (copper indium gallium (di)selenide) known for its potential to provide cost-effective solar electricity. The technology is currently awaiting scale-up for industrial applications.

Over the years the laboratory has boosted the photovoltaic conversion efficiency of flexible CIGS solar cells time and again, from 12.8% in 1999 – the group’s first world record – to 14.1% in 2005, 17.6% in 2010 and 18.7% in 2011.
What’s more, Empa’s new record efficiency for flexible solar cells now even exceeds the record value of 20.3% for CIGS solar cells on glass substrates – and equals the highest efficiencies for polycrystalline silicon wafer-based solar cells. 

Thin film, lightweight and flexible high-performance solar modules are attractive for numerous applications such as solar farms, roofs and facades of buildings, automobiles and portable electronics and can be produced using continuous roll-to-roll manufacturing processes that offer further cost reductions compared to standard silicon technologies. In other words, they have the potential to enable low-cost solar electricity in the near future. 

Now it is time for the next step, the scale-up of the technology to cover large areas in a cost-efficient roll-to-roll manufacturing process with an industrial partner”, says Gian-Luca Bona the Director of Empa. For this purpose, Empa is collaborating with Flisom, a start-up company involved in industrialization of flexible CIGS solar cells.

Music goosbump secret

Twenty years ago, the British psychologist John Sloboda conducted a simple experiment. He asked music lovers to identify passages of songs that reliably set off a physical reaction, such as tears or goose bumps. Participants identified 20 tear-triggering passages, and when Dr. Sloboda analyzed their properties, a trend emerged: 18 contained a musical device called an "appoggiatura."

Last year, Robert Zatorre and his team of neuroscientists at McGill University reported that emotionally intense music releases dopamine in the pleasure and reward centers of the brain, similar to the effects of food, sex and drugs. This makes us feel good and motivates us to repeat the behavior.

An appoggiatura is a type of ornamental note that clashes with the melody just enough to create a dissonant sound. "This generates tension in the listener," said Martin Guhn, a psychologist at the University of British Columbia who co-wrote a 2007 study on the subject. "When the notes return to the anticipated melody, the tension resolves, and it feels good."

Chills often descend on listeners at these moments of resolution. When several appoggiaturas occur next to each other in a melody, it generates a cycle of tension and release. This provokes an even stronger reaction, and that is when the tears start to flow.
"Someone Like You," which Adele wrote with Dan Wilson, is sprinkled with ornamental notes similar to appoggiaturas. In addition, during the chorus, Adele slightly modulates her pitch at the end of long notes right before the accompaniment goes to a new harmony, creating mini-roller coasters of tension and resolution, said Dr. Guhn.
To learn more about the formula for a tear-jerker, a few years ago Dr. Guhn and his colleague Marcel Zentner found musical excerpts—from Mendelssohn's "Trio for Piano" and Barber's "Adagio for Strings," for example—that reliably produce the chills and then measured the physiological reactions (heart rate, sweating, goose bumps) of listeners.
Chill-provoking passages, they found, shared at least four features. They began softly and then suddenly became loud. They included an abrupt entrance of a new "voice," either a new instrument or harmony. And they often involved an expansion of the frequencies played. In one passage from Mozart's Piano Concerto No. 23 (K. 488), for instance, the violins jump up one octave to echo the melody. Finally, all the passages contained unexpected deviations in the melody or the harmony. Music is most likely to tingle the spine, in short, when it includes surprises in volume, timbre and harmonic pattern.

"Someone Like You" is a textbook example. "The song begins with a soft, repetitive pattern," said Dr. Guhn, while Adele keeps the notes within a narrow frequency range. The lyrics are wistful but restrained: "I heard that you're settled down, that you found a girl and you're married now." This all sets up a sentimental and melancholy mood.

When the chorus enters, Adele's voice jumps up an octave, and she belts out notes with increasing volume. The harmony shifts, and the lyrics become more dramatic: "Sometimes it lasts in love, but sometimes it hurts instead."
Adele, the Grammy-winning singer-songwriter performed "Rolling In The Deep" from her latest album "21" at WSJ Cafe

When the music suddenly breaks from its expected pattern, our sympathetic nervous system goes on high alert; our hearts race and we start to sweat. Depending on the context, we interpret this state of arousal as positive or negative, happy or sad.


If "Someone Like You" produces such intense sadness in listeners, why is it so popular? Last year, Robert Zatorre and his team of neuroscientists at McGill University reported that emotionally intense music releases dopamine in the pleasure and reward centers of the brain, similar to the effects of food, sex and drugs. This makes us feel good and motivates us to repeat the behavior.

Measuring listeners' responses, Dr. Zatorre's team found that the number of goose bumps observed correlated with the amount of dopamine released, even when the music was extremely sad. The results suggest that the more emotions a song provokes—whether depressing or uplifting—the more we crave the song.


With "Someone Like You," Adele and Mr. Wilson not only crafted a perfect tear-jerker but also stumbled upon a formula for commercial success: Unleash the tears and chills with small surprises, a smoky voice and soulful lyrics, and then sit back and let the dopamine keep us coming back for more.

TED: Simon Sinek & Steve Jobs - Leadership by why

I first found an intersting speach from Simon Sinek today (under Most viewed on TED).


How great leaders inspire others by telling why.

On Simon's homepage was a video about purpose. You can skip to the end, where he summarise a few things about leadership in the military. It's worth hearing.


Then, I heard the speach from Steve Jobs who inspired Simon where he says follow your heart.



Steve mentioned a book 'Whole Earth Catalogue' that I wish I knew about when I was young.
I would had been a perfect, if I only had known english as today.
I like the end: Stay hungry. Stay foolish.

Startup Genome - The Growth cycle of Startup companies

Since February we've amassed a dataset of over 3200 high growth technology startups. Our latest research found that the primary cause of failure is premature scaling, an affliction that 70% of startups in our dataset possess.
The difference in performance between startups that scale prematurely and startups that  scale properly is pretty striking. We found that:

 - No startup that scaled prematurely passed the 100,000 user mark.
 - 93% of startups that scale prematurely never break the $100k revenue per month threshold.
 - Startups that scale properly grow about 20 times faster than startups that scale prematurely.

Tipping Point for the Spread of Ideas, just 10%


Scientists at Rensselaer Polytechnic Institute have found that when just 10 percent of the population holds an unshakable belief, their belief will always be adopted by the majority of the society.

The finding has implications for the study and influence of societal interactions ranging from the spread of innovations to the movement of political ideals. As an example, the ongoing events in Tunisia and Egypt appear to exhibit a similar process, according to Szymanski. "In those countries, dictators who were in power for decades were suddenly overthrown in just a few weeks."


"In general, people do not like to have an unpopular opinion and are always seeking to try locally to come to consensus. each of the individuals in the models "talked" to each other about their opinion. If the listener held the same opinions as the speaker, it reinforced the listener's belief. If the opinion was different, the listener considered it and moved on to talk to another person. If that person also held this new belief, the listener then adopted that belief.

How do you measure wellbeing and happiness


The Office for National Statistics in UK was asked by the Prime Minister David Cameron last November to find out - or at least to work out how to find out.
After a six month-long consultation the wellbeing project came to the conclusion of a crucial difference:
* happiness is one intangible thing.
* wellbeing is - they say - measurable in the same way our economy is.

The project leader said:
It is essential that the set of measures of well-being is relevant and well-based in what matters to people, both as individuals and for the UK as a whole

So, how will they do it? The study has been split into a search for two types of indicators - subjective ones about how we feel and objective measures of things that affect our wellbeing.

On top on 4 extra questions in the Integrated Household Survey (IHS), they plan to investigate four major areas:
* Childhood
* Economy and inequality
* Health
* Work/life balance

The first results are expected back in July 2012.

24h body clock - groundbreaking discovery

A group of Cambridge scientists have successfully identified the mechanism that drives our internal 24-hour clock, or circadian rhythm. It occurs not only in human cells, but has also been found in other life forms such as algae, and has been dated back millions of years.

"The implications of this for health are manifold. We already know that disrupted clocks – for example, caused by shift-work and jet-lag – are associated with metabolic disorders such as diabetes, mental health problems and even cancer."

A second study identified a similar 24-hour rhythm in marine algae. This groundbreaking research shows that body clocks are ancient mechanisms that have stayed with us through a billion years of evolution.
