Transumanismul, viitoarea etapa a civilizatiei umane

MIT engineers have developed a microfluidic device that replicates the neuromuscular junction—the vital connection where nerve meets muscle. The device, about the size of a U.S. quarter, contains a single muscle strip and a small set of motor neurons. Researchers can influence and observe the interactions between the two, within a realistic, three-dimensional matrix.
The researchers genetically modified the neurons in the device to respond to light. By shining light directly on the neurons, they can precisely stimulate these cells, which in turn send signals to excite the muscle fiber. The researchers also measured the force the muscle exerts within the device as it twitches or contracts in response.

Eu cred ca mai mult de 120 de ani nu rezisti ca om. Ani incepand de la nastere.
Pe de alta parte stiinta nu stie cum functioneaza nici creierul, nici ochiul, nici inima si nici multe altele. In general operatiile pe creier se fac eliminand parti din el. Nu se repara pt ca nu se stie cum. Creierul este 90% apa. Ochiul se banuieste ca formeaza imaginea pe retina, dar intreg procesul nu se cunoaste, doar se banuieste cu conurile, celule care sunt sensibile la lumina, celule sensibile la intuneric. Pe intuneric, nu bezna, vezi alb-negru. Nu se stie de ce, doar se banuieste. Nu se stie cum de functioneaza inima. Nu ma refer la cum e compartimentata, ci cum de se contracta si dilata. Contractia inimii este data de ioni de iod si sodiu, daca nu ma insel, dar mecanismul in sine nu se cunoaste. Nu se cunoaste nici impulsul electric initial de cine e dat. Cand esti mic embrion si iti porneste motorasul. Si multe multe altele nu se cunosc.
Ca idee, teoria aceea mi se pare can-can.

cum se face transplantul de inima daca nu stie cum functioneaza inima ?

interesant, pina la urma ateii cu bani se vor mintui mai repede decit credinciosii fara bani. vreau sa-l vad pe credinciosul ala ce va refuza tehnologia imortalitatii, pentru ca-i imoral.

IO.
Si nu doar ca e imoral, dar e foarte periculos, inclusiv in viata asta.
Din momentul in care esti legat de un computer, ti se pot face lucruri de care n-avem idee.

By significantly increasing the speed of functional MRI (fMRI), researchers funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have been able to image rapidly fluctuating brain activity during human thought. fMRI measures changes in blood oxygenation, which were previously thought to be too slow to detect the subtle neuronal activity associated with higher order brain functions. The new discovery that fast fMRI can detect rapid brain oscillations is a significant step towards realizing a central goal of neuroscience research: mapping the brain networks responsible for human cognitive functions such as perception, attention, and awareness.
Concludes Polimeni, "It had always been thought that fMRI had the potential to play a major role in these types of studies. Meaningful progress in cognitive neuroscience depends on mapping patterns of brain activity, which are constantly and rapidly changing with every experience we have. Thus, we are extremely excited to see our work contribute significantly to achieving this goal."

In order for a transistor to behave like a biological neuron, it must be capable of implementing neuron-like functions—in particular, weighted summation and threshold functions. These refer to a biological neuron's ability to receive weighted input signals from many other neurons, and then to sum the input values and compare them to a threshold value to determine whether or not to fire. The human brain has tens of billions of neurons, and they are constantly performing weighted summation and threshold functions many times per second that together control all of our thoughts and actions.
In the new study, the researchers constructed a neuron transistor that acts like a single neuron, capable of weighted summation and threshold functions. Instead of being made of silicon like conventional transistors, the neuron transistor is made of a two-dimensional flake of molybdenum disulfide (MoS2), which belongs to a new class of semiconductor called transition metal dichalcogenides.
One of the advantages of the neuron transistor is its operating speed. Although other neuron transistors have already been built, they typically operate at frequencies of less than or equal to 0.05 Hz, which is much lower than the average firing rate of biological neurons of about 5 Hz. The new neuron transistor works in a wide frequency range of 0.01 to 15 Hz, which the researchers expect will offer advantages for developing neuromorphic hardware.

Ia mai cerceteaza tu. Nodul sinoatrial... iti spune ceva. Este vorba de o oscilatie autointretinuta (similar oscilatoarelor din electronica)
