Ideea unui american, Alec Brownstein pe nume, transpusă – cu doar șase dolari – în locul de muncă visat:

Meet Alec Brownstein, senior copywriter at creative advertising shop Young & Rubicam (Y&R) New York. Last summer, Alec was just another tired, 28-year-old copywriter at a large international ad agency who wanted nothing more than to work at “a really creative shop for really creative [creative directors].”

 

While Googling his favorite creative directors last summer, Brownstein noticed that there were no sponsored links attached to their names. Since Brownstein Googles himself “embarassingly frequently,” he assumed that the creative directors did so as well, and thus he decided to purchase their names on Google AdWords.

 

“Everybody Googles themselves,” Brownstein explained. “Even if they don’t admit it. I wanted to invade that secret, egotistical moment when [the creative directors I admired] were most vulnerable.”

 

Since Brownstein was the only person bidding on the names of the five creative directors he most admired, he was able to get the top search spots for a mere 15 cents per click. Whenever someone ran a search for one of the creative directors’ names, the following message appeared at the top of the page: “Hey, [creative director's name]: Goooogling [sic] yourself is a lot of fun. Hiring me is fun, too” with a link to Brownstein’s website.

 

Over the next couple of months, Brownstein received calls from all but one of the creative directors whose names he had purchased. And finally, at the end of the year, he received a job offer from two: Scott Virtrone and Ian Reichenthal of Y&R New York.

 

The whole campaign cost him $6.

Nu reprezintă pentru nimeni o noutate faptul că – în România – cercetarea este codașă în lista de priorități a guvernanților, indiferent de coloratura lor politică. Cifrele brute vorbesc de la sine și nu lasă loc de nuanțe și interpretări. În acest context (vitreg), descoperirea cercetătorilor de la Institutul ”Victor Babeș” apare cu atât mai remarcabilă. Astfel, aceștia au descoperit un nou tip de celule, denumite telocite, celule care joacă un rol important în capacitatea de regenerare și reparare a țesuturilor și organelor din corpul omenesc, împreună cu celulele-stem.

Romanian researchers from “Victor Babes” National Institute for Research and Development in the Field of Pathology and Biomedical Sciences have discovered a cell type, which, together with stem cells could promote regeneration of heart muscle affected by stroke. Victor Babes Institute’s specialists have discovered by chance, while doing research on cells in the intestine, the presence of very small cells that help regenerate organs.

Santiago Ramón y Cajal discovered a particular cell type in the gut, which he named “interstitial neurons” more that 100 years ago. In the early 1970s, electron microscope (EM) studies showed that indeed a special interstitial cell type corresponding to the cells discovered by Cajal is localized in the gut muscle coat, but it became obvious that they were not neurons. Consequently, they were renamed “Interstitial Cells of Cajal”(ICC) and considered to be pace-makers for gut motility. For the past 10 years many groups were interested in whether or not ICC are present outside the gastrointestinal tract, and indeed, peculiar interstitial cells were found in: upper and lower urinary tracts, blood vessels, pancreas, male and female reproductive tracts, mammary gland, placenta, and, recently, in the heart as well as in the gut. Such cells, now mostly known as Interstitial Cajal-Like Cells (ICLC), were given different and confusing names. Moreover, ICLC are only apparently similar to canonical ICC. In fact, EM and cell cultures revealed very particular features of ICLC, which unequivocally distinguishes them from ICC and all other interstitial cells: the presence of 2–5 cell body prolongations that are very thin (less than 0.2 mm, under resolving power of light microscopy), extremely long (tens to hundreds of mm), with a moniliform aspect (many dilations along), as well as caveolae. Given the unique dimensions of these prolongations (very long and very thin) and to avoid further confusion with other interstitial cell types (e.g. fibroblast, fibrocyte, fibroblast-like cells, mesenchymal cells), was coined the term TELOCYTES for them, and TELOPODES for their prolongations, by using the Greek affix “telos”.

According to Laurenţiu Popescu, President of the Academy of Medical Sciences, the telocyte cells were highlighted by Romanian scholars and their existence was confirmed by independent teams from Italy, Germany, Britain and China. In tandem with stem cells, telocytes can help restore some vital organs like heart and brain.

“If we succeed to isolate, multiply them with stem cells, we can use effectively to treat heart attack,” said Professor Laurenţiu Popescu, M.D., Ph.D.

De aici. Cine vrea să cunoască mai multe despre istoria și detaliile descoperirii poate arunca o privire aici.

Lesne de înțeles, o finațare corespunzătoare a institutelor de cercetare care chiar produc rezultate științifice ar reprezenta o promovare mult mai bună pentru România, în loc de aruncat bani aiurea pe concerte și scene inutile marca Ridzi sau pe campanii de plagiat frunze marca Udrea & co. De pildă, comparați milionul de euro necesar Institutului ”Victor Babeș” cu sumele care se fură, cu acte în regulă, în România actuală…

PS Aflu că știrea nu este tocmai nouă, domnul Popescu acordând un interviu încă din luna aprilie revistei Viața Medicală, interviu în care acesta vorbește despre descoperirea telocitelor. Pesemne mass-media autohtonă nu a considerat subiectul destul de important pentru a fi strecurat în vreun jurnal de știri sau colț de tabloid, în cele patru luni scurse de atunci…

Acum ceva vreme fragmentul de mai jos făcea parte din manualul de filosofie pentru clasa a XII-a, capitolul „Dreptatea”:

[…]

— Întrebarea este ce a vrut să spună R. Daneel prin folosirea termenului „justiţie”.

— Din contextul conversaţiei noastre, el s-a referit la ceea ce am înţelege eu, dumneavoastră şi orice alt om, dar ce n-ar putea înţelege nici un robot.

— Domnule Baley, de ce nu-i cereţi să definească termenul?

Baley simţi că siguranţa începea să i se destrame. Se întoarse spre R. Daneel:

— Ei bine?

— Da, Elijah?

— Cum defineşti tu justiţia?

— Justiţia, Elijah, este ceea ce există când toate legile sunt aplicate.

— O definiţie bună pentru un robot, încuviinţă Fastolfe din cap. Dorinţa de a urmări aplicarea tuturor legilor a fost recent încorporată în Daneel. Pentru el, justiţia este un termen foarte concret, deoarece se bazează pe aplicarea legii, care la rândul ei se bazează pe existenţa unor legi specifice şi definite. Nu este vorba de nimic abstract. Un om poate recunoaşte faptul că, pe baza unui cod moral abstract, unele legi pot fi proaste, iar aplicarea lor injustă. Ce părere ai, R. Daneel?

— O lege injustă, răspunse egal R. Daneel, este o contradicţie în termeni.

— Aşa stau lucrurile pentru un robot, domnule Baley. Din acest motiv, nu trebuie să confundaţi justiţia dumneavoastră cu cea a lui R. Daneel.

Vorbeam mai deunăzi cu un prieten – programator freelance – despre ipoteza (demnă de luat în seamă) a plecării din țară. Printre argumentele schimbate, acesta mi-a spus foarte sincer: „N-am niciun motiv să plec din România; ceea ce fac eu pot face de oriunde, fie într-o cameră de hotel, o insulă pustie sau metropolă europeană, cât timp dispun de conexiune la Internet. Așa că nu văd de ce aș emigra, să-mi las în urmă toți prietenii și tot ceea ce m-a format ca persoană, pentru a mă dezrădăcina în altă parte. Am stat un an în Germania, trei luni în Paris, știu ce înseamnă Occidentul și mă simt mai bine în România.”

Desigur, cazul este unul particular. Este greu să convingi un doctor, plătit mai prost decât un liftier, sau un profesor ce câștigă pe sfert din remunerația unui șofer de minister, să rămână în România. Nu pasiunea pentru profesia aleasă, ci doar un masochism latent i-ar (mai) reține aici. De altfel, aceștia pleacă în număr tot mai mare.

Pentru cunoscători:

Matter and energy had ended and with it, space and time. Even AC existed only for the sake of the one last question that it had never answered from the time a half-drunken computer ten trillion years before had asked the question of a computer that was to AC far less than was a man to Man.

All other questions had been answered, and until this last question was answered also, AC might not release his consciousness.

All collected data had come to a final end. Nothing was left to be collected.

But all collected data had yet to be completely correlated and put together in all possible relationships.

A timeless interval was spent in doing that.

And it came to pass that AC learned how to reverse the direction of entropy.

But there was now no man to whom AC might give the answer of the last question. No matter. The answer — by demonstration — would take care of that, too.

For another timeless interval, AC thought how best to do this. Carefully, AC organized the program.

The consciousness of AC encompassed all of what had once been a Universe and brooded over what was now Chaos. Step by step, it must be done.

And AC said, "LET THERE BE LIGHT!"

And there was light—-

Isaac Asimov – The Last Question

Ceea ce majoritatea oamenilor uită.

Sau cum se „împăturește” o proteină:

Cei interesați pot arunca o privire aici.

Ne spune The Economist, citând ultimul European Social Survey. Astfel, cehii, francezii, britanicii și belgienii se situează pe primele locuri în ceea ce privește nefrecventarea bisericilor. La polul opus al fervoarei religioase se află ciprioții, grecii, polonezii și croații, mai puțin de 10% dintre respondenți declarând că nu frecventează serviciile religioase. Dacă România ar fi fost inclusă în  respectivul sondaj cu siguranță ne-am fi situat în jumătatea inferioară a clasamentului, căci la nivel verbal-declarativ românii sunt extrem de cucernici, religioși și „cu frică de Dumnezeu”. În fond vorbele nu costă nimic.

Murray Gell-Mann, descoperitorul quark-ului:

I’ve been warned Gell-Mann can be rather prickly when he feels his time is being wasted. To my relief, once we retire to his office he is amiable and gracious.

Gell-Mann’s work revolutionised our view of how matter works at the subatomic scale. In the 1950s and early 60s, when the catalogue of elementary particles was spiralling far beyond the familiar trio of proton, neutron and electron to reveal a menagerie of bizarre newcomers, particle physics was in desperate need of an organiser. No one did more to clear up the confusion than Gell-Mann, who came up with a tidy classification scheme that placed the particles into octets – groupings of eight.

He called his scheme the Eightfold Way – a playful allusion to the Noble Eightfold Path of Buddhism, which he happened to be reading about in preparation for a visit to India. The Eightfold Way soon led Gell-Mann to infer that the proton and neutron were not fundamental entities after all, but were in fact composites of a new kind of elementary particle. He called this particle the "quark", from a passage in James Joyce’s Finnegans Wake. Gell-Mann’s insight became the keystone of the standard model of particle physics, which explains most of the known fundamental forces and particles, and he earned the physics Nobel prize in 1969.[…]

Another pet project is an attempt to trace the majority of human languages back to a common root. Since the 19th century, linguists have been comparing languages to infer their common ancestry, but in most cases, Gell-Mann says, this kind of analysis loses the trail 6000 or 7000 years back. He says most linguists insist it is impossible to follow the trail any further into the past and – this is what truly rankles with him – "absurdly, they don’t even want to try".

Gell-Mann heads SFI’s Evolution of Human Languages (EHL) programme. The EHL linguists say they can go even further back by classifying language families into superfamilies and even into a super-superfamily. "What we’ve found," Gell-Mann explains, "is tentative evidence for a situation in which a huge fraction of all human languages are descended from one spoken around 20,000 years ago, towards the end of the last ice age." The team does not claim to account for all languages, though, and remains agnostic about whether they can eventually do so. "All of this just comes from following the data," he says.

Este remarcabil că un om la optzeci de ani își păstrează intacte energia, curiozitatea și disponibilitatea de a învăța lucruri noi, având în vedere lipsa de interes pentru orice formă de cunoaștere – dincolo de ceea ce implică remunerație imediată – a atâtor oameni tineri…

Human intelligence is puzzling. It is higher, on average, in some places than in others. And it seems to have been rising in recent decades. Why these two things should be true is controversial. This week, though, a group of researchers at the University of New Mexico propose the same explanation for both: the effect of infectious disease. If they are right, it suggests that the control of such diseases is crucial to a country’s development in a way that had not been appreciated before. Places that harbour a lot of parasites and pathogens not only suffer the debilitating effects of disease on their workforces, but also have their human capital eroded, child by child, from birth.

Christopher Eppig and his colleagues make their suggestion in the Proceedings of the Royal Society. They note that the brains of newly born children require 87% of those children’s metabolic energy. In five-year-olds the figure is still 44% and even in adults the brain—a mere 2% of the body’s weight—consumes about a quarter of the body’s energy. Any competition for this energy is likely to damage the brain’s development, and parasites and pathogens compete for it in several ways. Some feed on the host’s tissue directly, or hijack its molecular machinery to reproduce. Some, particularly those that live in the gut, stop their host absorbing food. And all provoke the host’s immune system into activity, which diverts resources from other things.[…]
