Allow me to introduce you to someone who has the potential to be very important in the future of Bitcoin. His name is Balaji Srinivasan, and he is the chairman and co-founder of 21 Inc. What is 21 Inc? 21 Inc. is the Bitcoin startup that secured the most venture capital of any Bitcoin company in history, at $116 million. What do they need $116 million in venture capital for? They are investing in “future proprietary products designed to drive mainstream adoption of Bitcoin.” With that in mind, the research of 21 Inc. has highlighted some interesting Bitcoin factoids. One Srinivasan released at the second annual Bitcoin Job Fair held last weekend in Sunnyvale, California regarding how big Bitcoin has become in the computing world.

Honestly, I looked online to find out what a petahash rate and a gigahash rate was, and that is one long rabbit hole, so I’ll leave the technical ramble to techies like Mr. Srinivasan. He makes the comparison to Google based on the fair assumption that they are using 1e7 servers, for 1e7 H/s per Xeon, and ~10 Xeons/server = 1 PH/s. One petahash equals 1,000,000 gigahash or 1000 terahashes. Bitcoin reached 1 PH/s of computing power/speed on September 15th, 2013. It is now normally working at over 350 PH/s, or over 350,000,000 GH/s.

” All of Google today would represent less than 1% of all of mining (Bitcoin operations worldwide). The sheer degree of what is happening in (Bitcoin) mining is not being appreciated by the press,” said Balaji Srinivasan at the Bitcoin Job Fair. “If we assume there are 10 million Google servers, and each of these servers is running, you can multiply that through and get one petahash. If they turned off all of their data centers and pointed them at Bitcoin (mining network), they would be less than 1% of the network.”

This is the energy source that will power the Singularity.

And everything else, too.

For more than 60 years, scientists have dreamed of a clean, inexhaustible energy source in the form of nuclear fusion.

And they’re still dreaming.

But thanks to the efforts of the Max Planck Institute for Plasma Physics, experts hope that might soon change.

Meanwhile there is something important going on in the fight against baldness.

As in the majority of tissues, the hair follicle has stem cells. There are two types of stem cells that are responsible for the continuous renewal of the follicles. The first type is called active stem cells and they start dividing quite easily. Stem cells of the second type are called quiescent and in case of the new hair growth they don’t start dividing as easily. At the same time, the new hair is based primarily on quiescent cells, which attracted close attention of researchers to these cells. At first people thought that baldness was due to this type of cells.

However, recent studies showed that bald men did have those quiescent cells in their follicles. The problem was that they didn’t divide at all and didn’t contribute to forming new hairs.

This means that even a bald person still has the potential to grow new hair, but because of lack of some regulatory factors quiescent cells can’t start replicating.

Elaine Fuchs was able to identify these regulatory factors in her study published in Cell. Apparently, it’s all about the transit-amplifying cells that are the progeny of the active stem cells.

The U.S. Food and Drug Administration announced on Oct. 27 that it has approved, for the first time, an oncolytic (cancer-killing) viral therapy in the United States. The drug was approved for use against late-stage melanoma, a deadly skin cancer that can be difficult to treat.

The approval came as the result of a recent Phase III study, which showed that more patients with late-stage melanoma, treated with a herpes cold sore virus designed to kill , had a better response when compared to a different treatment. Robert Andtbacka, M.D., from Huntsman Cancer Institute at the University of Utah and Howard L. Kaufman, M.D., from Rutgers Cancer Institute of New Jersey, led the multisite study, published May 26 online in the Journal of Clinical Oncology.

According to Andtbacka, “The goal of this targeted therapy is to treat late stage patients more effectively and with fewer side effects.”

These people have got a leg — or an arm — up on the future.

Thanks to the latest advancements in medical science, amputees are becoming part robot, with awe-inspiring artificial limbs that would make Luke Skywalker jealous.

These new limbs come armed with microprocessors and electrodes that sense muscle movement. Others can be controlled by a smartphone app. People missing limbs often tried to hide their prosthetics, but these New Yorkers are showing them off with pride.
Rebekah Marine.

Rebekah Marine had the modeling bug from a young age, playing dress-up as a kid and getting her mom to take her to try out for modeling agencies in New York.

The one problem? She was born without part of her right arm.

“I was just kind of quickly denied from [agencies] based on my quote-unquote disability,” the 28-year-old says.
