Gene Editing Is Now Cheap and Easy—and No One Is Prepared for the Consequences

Posted by in categories: bioengineering, biotech/medical, genetics

In April 2015, a paper by Chinese scientists about their attempts to edit the DNA of a human embryo rocked the scientific world and set off a furious debate. Leading scientists warned that altering the human germ line without studying the consequences could have horrific consequences. Geneticists with good intentions could mistakenly engineer changes in DNA that generate dangerous mutations and cause painful deaths. Scientists — and countries — with less noble intentions could again try to build a race of superhumans.

Human DNA is, however, merely one of many commercial targets of ethical concern. The DNA of every single organism — every plant, every animal, every bacterium — is now fair game for genetic manipulation. We are entering an age of backyard synthetic biology that should worry everybody. And it is coming about because of CRISPRs: clustered regularly interspaced short palindromic repeats.

Discovered by scientists only a few years ago, CRISPRs are elements of an ancient system that protects bacteria and other single-celled organisms from viruses, acquiring immunity to them by incorporating genetic elements from the virus invaders. CRISPRs evolved over millions of years to trim pieces of genetic information from one genome and insert it into another. And this bacterial antiviral defense serves as an astonishingly cheap, simple, elegant way to quickly edit the DNA of any organism in the lab.

Kyoto University scientists in Japan have developed a method for creating larger 2-D self-assembling DNA origami nanostructures.

Current DNA origami methods can create extremely small two- and three-dimensional shapes that could be used as construction material to build nanodevices, such as nanomotors, in the future for targeted drug delivery inside the body, for example. KurzweilAI recently covered advanced methods developed by Brookhaven National Laboratory and Arizona State University’s Biodesign Institute.

Intel 6th generation core processor for triple battery life and 2.5 times better performance

Posted by in categories: computing, energy

Intel Corporation introduced the 6th Generation Intel® Core™ processor family, the company’s best processors ever. The launch marks a turning point in people’s relationship with computers. The 6th Gen Intel Core processors deliver enhanced performance and new immersive experiences at the lowest power levels ever and also support the broadest range of device designs – from the ultra-mobile compute stick, to 2 in 1s and huge high-definition All-in-One desktops, to new mobile workstations.

There are over 500 million computers in use today that are four to five years old or older. They are slow to wake, their batteries don’t last long, and they can’t take advantage of all the new experiences available today.

Built on the new Skylake microarchitecture on Intel’s leading 14nm manufacturing process technology.

A Transfusion Of Young Blood Might Help You Live Longer, But Is It A Fountain Of Youth Or A Poisoned Chalice?

Posted by in categories: biotech/medical, life extension

GDF 11 has been publicised as another fountain of youth molecule, but with contradictory findings, does it live up to the hype, or could it be potentially harmful? It could be a bit of both.

We’re Officially Closer To Creating The World’s Most Powerful Computer

Posted by in categories: quantum physics, supercomputing

Tech giant, Intel has pledged $50 million (£33 million) to quantum computing research, which could ultimately give us a supercomputer unlike any machine we have known so far.

In an open letter, CEO Brian Krzanich announced a 10-year partnership with Delft University of Technology and TNO, the Dutch Organisation for Applied Research.

Describing the “exciting possibilities” about the research he said: “Quantum computing is one of the more promising areas of long-term research we’ve been exploring in our labs, with some of the smartest engineers in the world.

Nanotubes open new path toward quantum information technologies

Posted by in categories: computing, materials, nanotechnology, quantum physics, security

“Beyond implementation of quantum communication technologies, nanotube-based single photon sources could enable transformative quantum technologies including ultra-sensitive absorption measurements, sub-diffraction imaging, and linear quantum computing. The material has potential for photonic, plasmonic, optoelectronic, and quantum information science applications…”


In optical communication, critical information ranging from a credit card number to national security data is transmitted in streams of laser pulses. However, the information transmitted in this manner can be stolen by splitting out a few photons (the quantum of light) of the laser pulse. This type of eavesdropping could be prevented by encoding bits of information on quantum mechanical states (e.g. polarization state) of single photons. The ability to generate single photons on demand holds the key to realization of such a communication scheme.

By demonstrating that incorporation of pristine into a silicon dioxide (SiO2) matrix could lead to creation of solitary oxygen dopant state capable of fluctuation-free, room-temperature single , Los Alamos researchers revealed a new path toward on-demand single photon generation. Nature Nanotechnology published their findings.

Finding Artificial Intelligence Through Storytelling — An Interview with Dr. Roger Schank

Posted by in categories: machine learning, robotics/AI

The media is all-abuzz with tales of Artificial Intelligence (AI). The provocative two-letter symbol conjures up images of invading autonomous robot drones and Terminator-like machines wreaking havoc on mankind. Then there’s the pervading presence of deep learning and big data, also referred to as artificial intelligence. This might leave some of us wondering, is artificial intelligence one or all of these things?

In that sense, AI leaves a bit of an ambiguous trail – there does not seem to be a clear definition, even amongst scientists and researchers in the field. There are certainly many different branches of AI. I asked Dr. Roger Schank, Professor Emeritus at Northwestern University, for a more clear definition; he told me that artificial intelligence is not big data and deep learning algorithms, at least not in the pure sense of the definition.

Roger emphasizes that intelligence has everything to do with the intersection of learning and interaction and memory. “I will tell you the number one thing people do, it’s pretty obvious – they talk to each other. Guess how hard that is? That is phenomenally hard, that is the subsection of AI called natural language processing, the part that I worked on my whole life, and I understand how far away we are from that.”

Take a “simple” AI concept, such as how to create a computer that plays chess, to better understand the challenge. There are, more or less, two approaches to creating an intelligent machine that can play chess like a champion. The first approach requires programming the computer to predict thousands of moves ahead of time, while the second approach involves building a computer system that tries to imitate a grand master. In the historical pursuit of how to create an artificially intelligent entity, a vast majority of scientists chose the first option of programming based on prediction.
