Certainly, something unusual is happening in the process by which the egg cell sends out signals to reprogram its new nucleus and put the developmental genes back into action.
The system even enables cardiologists to test and reprogram pacemakers or implanted defibrillators from the other side of the globe.
But the second paper, published in Nature by Lawrence Goldstein of the University of California, San Diego, and his colleagues, shows how stem cells can be of use even if they do not lead directly to treatment.Since 2006 researchers have been able to reprogram adult cells into an embryonic state, using proteins called transcription factors.
Goldman is also being more open with clients, telling them exactly how much it will earn from transactions and what different roles it may be playing.As important are its efforts to reprogram the firm's culture.
He saw reconfigurable logic as a way of speeding up computers by enabling them to reprogram themselves to handle different jobs.
Yahoo! and other Web firms worry that they may have to reprogram their sites to comply with many different jurisdictions and in the process get snarled by conflicting national laws.
Analog devices are notoriously difficult to design and reprogram.
He has managed to reprogram mouse connective-tissue cells so that they develop into cardiac muscle cells, and has tested them in the hearts of mice that have had heart attacks.
He had shown how four signal proteins can reprogram adult cells into a pluripotent state.
It has not been possible to reprogram them (like a digital device) to do many things even adequately.However, as work advances, neuromorphic chips will doubtless evolve to be general purpose in a different sense.
In them, she claimed that she and her colleagues had found a simple way to reprogram ordinary mouse cells, persuading them to transform themselves into pluripotent cells.Making pluripotent cells by reprogramming ordinary cells avoids the need to harvest them from embryos, their natural habitat, which is an ethically delicate matter.
