Virtual Currencies Are As Old As Favors
Posted by Samson Williams in categories: bitcoin, cryptocurrencies, disruptive technology, economics, finance
I owe Jack Shaw a favor. Itâs one of those, âThis one time in CambodiaâŠâ type of favors. We wonât speak of it beyond perhaps a nod and wink. Itâs not written down anywhere; the details of such are so vague as to be almost non existent, while encompassing the known universe. It expires upon death, of the sun; and can be redeemed whenever and by another person who need only walk up to me and say, âJack Shaw sent me. He says to tell you ________â. And tada, that favor has been redeemed for value.
Jack would call this favor a âmarker.â Itâs more valuable than your house, the Empire State Building & 100k Bitcoins combined. It can even be redeemed for something even more precious, my time or an opportunity or access to my network. You know, those things that money canât buy. Well, you can lease my time from time to time.
Favors, markers and promises are humanitiesâ first virtual currencies.

Brain âpacemakerâ could prevent tremors and seizures for Parkinsonâs and epilepsy sufferers
Posted by Genevieve Klien in categories: biotech/medical, neuroscience
A âpacemakerâ for the brain is on the horizon to prevent people with Parkinsonâs and epilepsy suffering from seizures and tremors.
The device is made up of two tiny array of electrodes which sit inside the skull, and link to a circuit board on the side of the head.
The âpacemakerâ records the normal electrical current of the brain continually and if it notices a change of rhythm immediately fires a stimulating charge to coax the pulse back to normal.

Physicists record âlifetimeâ of graphene qubits
Posted by Genevieve Klien in categories: computing, particle physics, quantum physics
Researchers from MIT and elsewhere have recorded, for the first time, the âtemporal coherenceâ of a graphene qubitâmeaning how long it can maintain a special state that allows it to represent two logical states simultaneously. The demonstration, which used a new kind of graphene-based qubit, represents a critical step forward for practical quantum computing, the researchers say.
Superconducting quantum bits (simply, qubits) are artificial atoms that use various methods to produce bits of quantum information, the fundamental component of quantum computers. Similar to traditional binary circuits in computers, qubits can maintain one of two states corresponding to the classic binary bits, a 0 or 1. But these qubits can also be a superposition of both states simultaneously, which could allow quantum computers to solve complex problems that are practically impossible for traditional computers.
The amount of time that these qubits stay in this superposition state is referred to as their âcoherence time.â The longer the coherence time, the greater the ability for the qubit to compute complex problems.

A Closer Look At What A Stem Cell Is: Our Cellsâ Diverse Regenerative Capabilities
Posted by Genevieve Klien in categories: biotech/medical, mapping, neuroscience
For several decades now, one of the buzz words in the medical field has been âstem cellâ. It has been said to aid in treating illnesses like multiple sclerosis, amyotrophic lateral sclerosis, Alzheimerâs disease, and heart diseases.
For the past three years, researchers at the Hubrecht Institute in the Netherlands have been painstakingly cataloging and mapping all the proliferating cells found in mouse hearts, looking for cardiac stem cells. The elusive cells should theoretically be able to repair damaged heart muscle, so the stakes in finding them have been high.
This week, however, Proceedings of the National Academy of Sciences is scheduled to announce the results of the Hubrecht teamâs work: no evidence of cardiac stem cells at all.

Ebola-fighting human protein offers hope for new drugs
Posted by Genevieve Klien in category: biotech/medical
During 2014âs Ebola outbreak, there were no treatments on hand to fight the virus. Now, researchers have found a human protein that could change that.
