TOPIC IS UNDER CONSTRUCTION
Transhumanizmus je filozofia, ktorá môže, a mala by, potiahnu? ľudstvo na vyššiu fyzickú, mentálnu, sociálnu i kultúrnu úroveň. Podporuje výskum a kreativitu v takých oblastiach, ako je predlžovanie života, kryonika, nanotechnológie, biotechnológie, pozdvihnutie fyzických a mentálych zručností, prepojenie ľudského vedomia s počítačmi či nadrozmerné inžinierstvo. Fantázia, ani vedecký pokrok nepoznajú hranice a koniec nie je nikdy blízko.


Základné princípy transhumanizmu:

Zmena Usiluj o odstránenie obmedzení nášho biologického a intelektuálneho dedičstva, fyzikálnych limitov nášho prostredia, kulturálnych a historických limitov našej spoločnosti, ktoré by bránili individuálnemu a spoločnému pokroku.
Pragmatizmus Použi všetky spôsoby, ktoré tento cieľ priblížia. V súčasnosti medzi najefektívnejšie takéto spôsoby patrí vedecký výskum a technologický pokrok a spolupráca s médiami.
Memetická propaganda Podporuj šírenie transhumnistických princípov a cieľov, vedome choď príkladom a bojuj proti technofóbii, nátlaku a násiliu, antihumanizmu a ďalším deštruktívnym ideológiám.
Čin Je jedno či podporou transhumanizmu a extropie nasleduješ zdravotné, intelektuálne alebo finančné ciele, spoločenský úspech či uplatnenie v politike, vždy choď vlastnou cestou. Spolupracuj s ďalšími inovátormi a optimistami v snahe naplni? vlastné a globálne ciele.
Diverzita Podporuj snahu ľudí rás? a prispôsobova? sa stále meniacemu vesmíru. Toleruj ľudí rôznych učení a názorov, ktorí nebránia tvojej vlastnej ceste.

Tieto princípy sa nauč naspamä? a recituj ich každý deň pred polnocou otočený pipíkom k partnerke(ovi)

A University of Utah physicist took a step toward developing a superfast computer based on the weird reality of quantum physics by showing it is feasible to read data stored in the form of the magnetic “spins” of phosphorus atoms.

“Our work represents a breakthrough in the search for a nanoscopic [atomic scale] mechanism that could be used for a data readout device,” says Christoph Boehme, assistant professor of physics at the University of Utah. “We have demonstrated experimentally that the nuclear spin orientation of phosphorus atoms embedded in silicon can be measured by very subtle electric currents passing through the phosphorus atoms.”

The study by Boehme and colleagues in Germany will be published in the December issue of the journal Nature Physics and released online Sunday, Nov. 19.

“We have resolved a major obstacle for building a particular kind of quantum computer, the phosphorus-and-silicon quantum computer,” says Boehme. “For this concept, data readout is the biggest issue, and we have shown a new way to read data.”

Boehme, who joined the University of Utah faculty earlier this year, conducted the study with Klaus Lips – a former colleague at the Hahn-Meitner Institute in Berlin – and with graduate students Andre Stegner and Hans Huebl and physicists Martin Stutzmann and Martin S. Brandt of the Technical University of Munich.

A Bit about Quantum Computing

In modern digital computers, information is transmitted by flowing electricity in the form of electrons, which are negatively charged subatomic particles. Transistors in computers are electrical switches that store data as “bits,” in which “off” (no electrical charge) and “on” (charge is present) represent one bit of information: either 0 or 1.

For example, with three bits, there are eight possible combinations of 1 or 0: 1-1-1, 0-1-1, 1-0-1, 1-1-0, 0-0-0, 1-0-0, 0-1-0 and 0-0-1. But three bits in a digital computer can store only one of those eight combinations at a time.

Quantum computers, which have not been built yet, would be based on the strange principles of quantum mechanics, in which the smallest particles of light and matter can be in different places at the same time.

In a quantum computer, one “qubit” – quantum bit – could be both 0 and 1 at the same time. So with three qubits of data, a quantum computer could store all eight combinations of 0 and 1 simultaneously. That means a three-qubit quantum computer could calculate eight times faster than a three-bit digital computer.

Typical personal computers today calculate 64 bits of data at a time. A quantum computer with 64 qubits would be 2 to the 64th power faster, or about 18 billion billion times faster. (Note: billion billion is correct.)

Researchers are exploring many approaches to storing and processing information in nanoscopic form – on the scale of molecules and atoms, or one billionth of a meter in size – for quantum computing. They include optical quantum computers that would hold data in the form of on-off switches made of light, ions (electrically charged atoms), the size or energy state of an electron’s orbit around an atom, so-called “quantum dots” of material and the “spins” or magnetic orientation of the centers or nuclei of atoms.

A New Spin on Quantum Computers

Boehme’s new study deals with an approach to a quantum computer proposed in 1998 by Australian physicist Bruce Kane in a Nature paper titled “A silicon-based nuclear spin quantum computer.” In such a computer, silicon – the semiconductor used in digital computer chips – would be “doped” with atoms of phosphorus, and data would be encoded in the “spins” of those atoms’ nuclei. Externally applied electric fields would be used to read and process the data stored as “spins.”

Spin is difficult to explain. A simplified way to describe spin is to imagine that each particle – like an electron or proton in an atom – contains a tiny bar magnet, like a compass needle, that points either up or down to represent the particle’s spin. Down and up can represent 0 and 1 in a spin-based quantum computer, in which one qubit could have a value of 0 and 1 simultaneously.

In the new study, Boehme and colleagues used silicon doped with phosphorus atoms. By applying an external electrical current, they were able to “read” the net spin of 10,000 of the electrons and nuclei of phosphorus atoms near the surface of the silicon.

A real quantum computer would need to read the spins of single particles, not thousands of them. But previous efforts, which used a technique called magnetic resonance, were able to read only the net spins of the electrons of 10 billion phosphorus atoms combined, so the new study represents a million-fold improvement and shows it is feasible to read single spins – something that would take another 10,000-fold improvement, Boehme says.

But the point of the study, he adds, is that it demonstrates it is possible to use electrical methods to detect or “read” data stored as not only electron spins but as the more stable spins of atomic nuclei.

“We discovered a mechanism that will allow us to measure the spins of the nuclei of individual phosphorus atoms in a piece of silicon when the phosphorus is close [within about 50 atoms] to the surface,” Boehme says. With improved design, it should be possible to build a much smaller device that “lets us read a single phosphorus nucleus.”

Details of the Experiment

The researchers used a piece of silicon crystal about 300 microns thick – about three times the width of a human hair – less than 3 inches long and about one-tenth of an inch wide. The silicon crystal was doped with phosphorus atoms. Phosphorus atoms were embedded in silicon because too many phosphorus atoms too close together would interact with each other so much that they couldn’t store information. The concept is that the nuclear spin from one atom of phosphorus would store one qubit of information.

The scientists used lithography to print two gold electrical contacts onto the doped silicon. Then they placed an extremely thin layer of silicon dioxide – about two billionths of a meter thick – onto the silicon between the gold contacts. As a result, the device’s surface had tiny spots where the spins of phosphorus atoms could be detected.

The scientists applied a tiny voltage to the gold contacts, creating an electrical current perhaps 10,000 times smaller than that produced by an AA-size battery, Boehme says. When the current was measured during 100 millionths of a second, it stayed constant, indicating the spins of the phosphorus atoms in the silicon were random, with half pointing up and half pointing down.

Then the device was chilled with liquid helium to 452 degrees below zero Fahrenheit. That made most of the phosphorus spins point down. Next, the researchers applied a magnetic field and microwave radiation to the sample, which makes the phosphorus spins constantly flop up and down in concert for a few billionths of a second.

As a result, the electrical current fluctuated up and down.

“That is basically a readout of phosphorus electron spins,” which, in turn, also can be used to determine the spins of the phosphorus atoms’ nuclei based on a previously known relationship between electron spins and nuclear spins, Boehme says.

While Boehme is excited by this advance, numerous obstacles remain before quantum computing becomes a reality.

“If you want to compare the development of quantum computers with classical computers, we probably would be just before the discovery of the abacus,” he says. “We are very early in development.”

V rámci oslav 125. výročí založení T. A. Edisonem požádal [custompublish.com] časopis Science více než stovku předních vědců, aby odhadli 25 důležitých otázek, na které bychom měli najít odpověď během příštích 25 let. Jak napsal v úvodníku čísla šéfredaktor časopisu Donald Kennedy: správně položené otázky jsou klíčové pro formování budoucí podoby vědy. Nepostradatelnými vlastnostmi dobrých otázek je podle Kennedyho zejména to, že jsou zodpověditelné a odpovědi na ně lze testovat. Paradoxně i správné odpovědi často vedou na ještě zásadnější otázky. Předpovědi, že věda již hlavní problémy vyřešila v minulosti několikrát dramaticky selhaly.

Na jaké otázky bychom měli znát odpověď na konci dalšího čtvrtstoletí?

* Do jaké míry jsou spojeny individuální genové variace se zdravím?
* Mohou být fyzikální zákony sjednoceny?
* Do jaké míry lze prodloužit lidský věk?

Quantum bubbles are the key

As futuristic as quantum computers seem, what with all those qubits and entangled atoms, here is an idea that promises to make atom-based quantum computers look passé even before anyone has built a full-sized version.
It seems that bubbles of electrons lined up in ultracold liquid helium could be used to build a quantum computer capable of carrying out a staggering 1030 simultaneous calculations.

To carry out these simultaneous calculations, quantum computers normally exploit entities such as atoms and molecules, which can be in several quantum states at once, to encode bits in those quantum states – the famous qubits. But Weijun Yao of Brown University in Providence, Rhode Island, wants to replace atoms with curious things called electron bubbles.

To make an electron bubble, start with liquid helium that has been cooled below 2.17 kelvin so that it behaves like a superfluid, a state of matter with zero viscosity. Now inject a fast-moving electron into the superfluid. When the electron eventually slows to a halt after numerous collisions with helium atoms, it creates a cavity about 3.8 nanometres across by repelling nearly 700 atoms' worth of helium around it (New Scientist, 14 October 2000, p 24).

It is this cavity that makes the electron bubble so very valuable. In a quantum computer, the quantum entities need to be isolated from their surroundings to preserve their fragile states. "What could be more isolated than an electron in a bubble?" asks Yao. "The electron inside each bubble interacts very weakly with the background helium atoms."

Yao says 0s or 1s could be encoded in the electrons' spins. In the presence of a magnetic field, the spin can either be parallel or anti-parallel to the field. Crucially, an electron's spin can exist in both states at the same time, enabling the qubit to be both 0 and 1.

According to Yao, large numbers of electrons, each in its own bubble, can be neatly caged using a combination of a device called a linear quadrupole trap, which traps the electrons in a line, and a set of conducting rings, which create a voltage "valley" for each bubble (see Diagram).

All the spins can be initialised to the same value by cooling the apparatus to 0.1 kelvin. You can then manipulate the electrons by applying a combination of a magnetic field gradient along the line and varying the frequency of the voltages in the quadrupole trap. This changes the spin of individual electrons and makes them interact to perform logicgate operations (www.arxiv.org/ cond-mat/0510757). To read the spin of an electron, the voltage at the end of the electron chain can be lowered so that each bubble drifts in the magnetic field gradient at a velocity that depends on the electron's spin. This drift velocity can be read using lasers.

Because each qubit carries two values, a quantum computer with two qubits could carry out four parallel calculations, one with three qubits eight calculations, and so on. "I see no major technical obstacles to the system I envisage working with 100 qubits," says Yao. "That means it could do 1000 billion billion billion operations all at once."

Genetici spomalili starnutie. Na nesmrteľnos? si ale počkáme
LONDÝN/BRATISLAVA (mq) - Genetickým experimentom vedci vytvorili organizmy, ktoré žijú šes?krát dlhšie, ako za normálnych okolností. Zlepšili sa tak aj vyhliadky na gentické predĺženie života ľudí.
Výsledky ich práce sú prekvapivo veľmi dobré. Nemožno teda vylúči?, že sa im podarilo odhali? jedno zo základných tajomstiev mechanizmu, ktorý riadi rýchlos? starnutia, uviedol britský denník Guardian.
Testy vedci z Univerzity v Južnej Kalifornii robili na jednobunkových organizmoch, ktoré prepli do tzv. ,,módu extrémneho prežívania." Namiesto rýchleho rastu jednobunkovce lepšie odolávali poškodeniam a boli schopné opravi? genetické chyby, ktoré môžu v neskoršom veku vyvola? rakovinové ochorenia.
,,Keď robíte takéto genetické manipulácie, môžete úžasne predlži? život," vyhlásil pre Guradian Valter Longo, biomedicínsky gerentológ z Kalifornie. ,,Veríme, že podobný mechanizmus funguje aj v zložitejších organizmoch. Momentálne pracujeme na myších a ľudských bunkách," dodal.
,,Nie sme ďaleko od výskumu takých liekov, ktoré výrazne spomalia starnutie. Netvrdím, že budeme ži? šes?krát dlhšie, no môžme spomali? poškodenia DNA, ktoré sa hromadia s vekom, čím môžme ochráni? ľudí pred rakovinou," uviedol Longo. Vedci predpokladajú, že výskum na zvieratách bude trva? aspoň desa? rokov. Potom budú môc? prejs? na človeka. ,,Chápem, že sa hráme so životom a smr?ou. Preto musíme by? opatrní," dodal gerentológ.

Přednášku na téma Bioetika a občanství ve 21. století přednese v pondělí 21.11. v Praze výkonný ředitel Světové transhumanistické organizace [transhumanism.org] Dr. James Hughes [changesurfer.com].

Akce, kterou spolupořádá Česká asociace transhumanistů, se koná od 18 hodin v Klubu knihovny Vysoké školy ekonomické, náměstí W. Churchilla 4, Praha 3. Klub knihovny se nachází v takzvané Staré budově VŠE. Vstup je hlavním vchodem z náměstí W. Churchilla, poté po schodišti do mezipatra. Klub je přímo proti vstupním dveřím knihovny.

Spojení MHD: tramvaje 5, 9, 24, 26 - zastávka Husinecká, bus 135 - zastávka Náměstí Winstona Churchilla.

Pokroky výpočetní techniky, biotechnologie a nanotechnologie povedou podle řady renomovaných vědců k radikálnímu prodloužení lidského života. "Budeme moci ovlivnit základní vlastnosti lidského těla jako je inteligence, délka života, fyzická kondice či přitažlivost. Tyto možnosti mohou zásadně změnit kvalitu lidského života", říká Dr. James Hughes, profesor lékařské etiky na Trinity College, Hartford University v Connecticutu v USA.

Vize technologického zdokonalování člověka se stává ohniskem konfliktu mezi zastánci nejnovějších technologií a konzervativci, kteří věří, že samotná podstata lidství se ocitla v ohrožení, a prosazují přísnou regulaci až potlačování některých směrů výzkumu. Dr. Hughes je zastáncem třetí cesty, která by zaručila maximální užitek získaný díky novým technologiím pro celou společnost.

"Je nutné zajistit nejen bezpečnost vývoje nových technologií, ale především jejich dostupnost pro široké vrstvy obyvatel", říká Dr. Hughes. Podle Dr. Hughese je nutné najít způsob, jak zajistit rovný a spravedlivý přístup všech vrstev společnosti k možnostem, které tyto technologie v budoucnu nabídnou.

Science fiction writers, computer theorists, amateur roboteers - they have all dreamed and argued about the feasibility of robots reproducing themselves.


Now robotics experts at Cornell University say they have built a machine that can build copies of itself - albeit at a very basic level.

And while it has no other useful function, it proves a principle that could be extended to make robots that could replicate themselves or at least repair themselves - allowing them to operate in hazardous environments such as space.

The robot consists of several identical modular cubes - known as molecubes - each of which contain a complete computer program for replication.

A complete robot is made up of a series of cubes linked together by electromagnets on their faces. These allow the cubes to selectively attach and detach from each other.

Each cube is divided in half diagonally letting a robot composed of several cubes to bend, reconfigure and manipulate other cubes.

The replication process runs as follows. A robot consisting of four cubes bends over and deposits one of its cubes on a table. The remaining three cubes pick up additional cubes from feeding stations and transfer them to the new robot, which assists in the process by standing itself up.

The robots are very dependent on their environment, drawing power through contacts on the surface of the table and cannot "reproduce" unless researchers "feed" them with additional cubes.

But despite their simplicity, the developers say that the machines still prove that self-reproduction is possible and "not unique to biology".

Barely a week goes by without a team of scientists coming up with another potential application for wireless sensors.

These are tiny, battery-powered electric chips covered with various types of film for sensing odour, pressure, temperature or movement - and can be used to monitor everything from our health to the environment.

Finnish experts have now developed specially-adapted sensors for use in prison cells - providing early warnings if inmates become agitated or have a medical emergency.

The sensors are fitted between the floors of jail cells and linoleum floor covers, where they can detect movements in the room as well as inmates' vital signs such as respiration and heart-rate.

The sensor will alert police officers either in a police station or wirelessly if - as is often the case in small stations or those in isolated areas - the station is temporarily unmanned.

The technology, developed by Finnish company Emfit, reduces the risk of prisoners putting themselves and others at risk or causing damage if, for example, they are drunk or on drugs - without the need for officers to watch the cells constantly.

The sensors are made of a nano-modified polymer film. A high-pressure gas expansion system is used to introduce microscopic bubbles into the film, which is then charged and fitted with electrodes. Changes in the film thickness - caused by footsteps or heavy breathing - produce an electrical charge that can be measured.

Emfit say the technology, which is undergoing trials in Finnish police stations, is also being used to develop a baby's cot with sensors under the mattress.

By keeping a close eye on baby's breathing, heartbeat and movement, scientists hope the technology will reduce cot deaths by alerting carers when a baby's vital signs become irregular.

Snails are helping experts in their search for a "Viagra for the brain".

Scientists exploring ways of treating memory loss - one of the common symptoms of diseases such as Alzheimer's - are trying to isolate brain molecules that build up and maintain long-term memory and learning.

If these molecules can be chemically enhanced to improve long-term memory or speed up the learning process in animals, then this could feed into human drug research.

Scientists from the University of Sussex say humans share important characteristics with snails, unchanged by evolution, making the molluscs ideal subjects for their research.

These similarities include the basic molecular mechanism which controls long-term memory and learning through the activation or suppression of a protein called CREB.

The team will try to learn how to inhibit quickly-learned memory and improve weaker, more slowly-acquired memory by using chemicals to stimulate or suppress the release of CREB.

Snails are also useful to the investigation because they have large neurons which are easier to identify and manipulate under a microscope than smaller mammal nerve cells.

Je potesujuce ze metoda vedy zase raz podala odpoved "ano" otazke na ktoru by mnohi filozofi odpovedali "nie".

Postulat 1: Replikator je zostrojitelny.

A kdeže kto odpovedal že to nie je možné? A ak mi takého nájdeš, kdeže je "filozofi" od filozofa?

dnes som cital v jednom zahranicnom periodiku ze microsoft si dal patentovat vyuzitie ludskeho tela ako siete na prenos dat a energie. asi desat rokov potom co sa podobne veci robili na MIT, a osem rokov od kedy si dvaja ludia podali ruky a vymenili si tak cisla kreditiek.
to ze ma tento patent prave tato "revolucna a inovatorska" firma ma trochu mrzi, ale verim, ze sikovny pravnik alebo vedec to dokaze obist.
