Dorian Nakamoto thanks bitcoin users for donations after Newsweek flub

The California man who claims he was wrongfully identified as the founder of bitcoin now says that bitcoin users have given him the equivalent of $23,000 for all his trouble.

Dorian Satoshi Nakamoto appeared in a short YouTube video Tuesday, thanking users of the cryptocurrency who have given him money and supported him through the media firestorm that began earlier this year.

Nakamoto was the subject of an extensive Newsweek piece in which the magazine purported to identify the inventor of the mysterious currency that, according to some prospectors, is on track to becoming a legitimate part of the international economy.


Drones on demand using Gofor

Gofor provides drones on demand. Using our mobile app, you can task a drone to complete a variety of helpful tasks. “Uber for drones”. http://gofordrones.com

San Francisco, Cali — April 6th 2014 - Gofor, a Bay Area startup, announces the launch its new mobile app of the same name, created to provide drones on demand. “Like Uber for Drones”, Gofor enables users to task drones to help them with a variety of tasks.

The consumer drone market has exploded over the last couple years. Unfortunately, the most exciting technologies are typically reserved for the military; consumer drones meanwhile mostly resemble child’s toys and RC helicopters, capable of nothing more than novelty aerial imaging.

No longer.

Gofor is poised to take the consumer drone market to the next level. With a new fleet of drones on demand, Gofor will make this technology useful to the consumer — capable of providing users with a multitude of services.

Using the Gofor app, drones can be requested to perform one of five preset task assignments. From location scouting to home security, Gofor’s tasks are basic, but undeniably helpful. Users of apps like Uber or Lyft will be familiar with the map-based dispatch interface. Drones in the vicinity appear over the map, and an approximate ETA is shown depending on the requested task. Depending on the task, drones either operate autonomously or are flown by skilled operators.

Gofor adds an entirely new layer of service to the consumer drone market. The app will be available for all iOS devices, with Android to come early 2015. The initial release is limited to five cities in the US (SF being the only public test market).

Right now, many major drug companies’ business practices keep their own profits high while keeping medicines out of the hands of millions of people who need them. Until we change the way medicines are developed and marketed, too many people will go without needed treatment because quality medicines are not available to them.

DNA-Based Nanocomputers Injected Into Live Cockroaches, Will Deliver Drugs Directly to Diseased Cells

It’s a computer – inside a cockroach. Nano-sized entities made of DNA that are able to perform the same kind of logic operations as a silicon-based computer have been introduced into a living animal.

The DNA computers – known as origami robots because they work by folding and unfolding strands of DNA – travel around the insect’s body and interact with each other, as well as the insect’s cells. When they uncurl, they can dispense drugs carried in their folds.

“DNA nanorobots could potentially carry out complex programs that could one day be used to diagnose or treat diseases with unprecedented sophistication,” says Daniel Levner, a bioengineer at the Wyss Institute at Harvard University.

Levner and his colleagues at Bar Ilan University in Ramat-Gan, Israel, made the nanobots by exploiting the binding properties of DNA. When it meets a certain kind of protein, DNA unravels into two complementary strands. By creating particular sequences, the strands can be made to unravel on contact with specific molecules – say, those on a diseased cell. When the molecule unravels, out drops the package wrapped inside.

…The team says the accuracy of delivery and control of the nanobots is equivalent to a computer system. “This is the first time that biological therapy has been able to match how a computer processor works,” says co-author Ido Bachelet of the Institute of Nanotechnology and Advanced Materials at Bar Ilan University. “Unlike electronic devices, which are suitable for our watches, our cars or phones, we can use these robots in life domains, like a living cockroach,” says Ángel Goñi Moreno of the National Center for Biotechnology in Madrid, Spain. “This opens the door for environmental or health applications.”

DNA has already been used for storing large amounts of information and circuits for amplifying chemical signals, but these applications are rudimentary compared with the potential benefits of the origami robots.
