DARPA head on AI dangers: ‘It’s not one of those things that keeps me up at night’

Posted by in categories: military, robotics/AI

“At least in the Defense Department today, we don’t see machines doing anything by themselves,” he said, noting that agency researchers are intensely focused on building “human-machine” partnerships. “I think we’re a long way off from a generalized AI, even in the third wave in what we’re pursuing.”


Artificial intelligence does not yet pose a serious threat to humans, according to the head of the Defense Advanced Research Agency. Though the military is rushing to improve its AI capabilities, DARPA Director Dr. Steven H. Walker said AI remains “a very fragile capability.”

Scientists crack the CRISPR code for precise human genome editing

Posted by in category: biotech/medical

Scientists at the Francis Crick Institute have discovered a set of simple rules that determine the precision of CRISPR/Cas9 genome editing in human cells. These rules, published in Molecular Cell, could help to improve the efficiency and safety of genome editing in both the lab and the clinic.

Despite the wide use of the CRISPR system, rational application of the technology has been hindered by the assumption that the outcome of genome editing is unpredictable, resulting in random deletions or insertions of DNA regions at the target site.

Before CRISPR can be safely applied in the clinic, scientists need to make sure that they can reliably predict precisely how DNA will be modified.

Scientists are developing a breakthrough test that uses gold to detect all types of cancer in 10 minutes

Posted by in categories: biotech/medical, innovation

  • Scientists at the University of Brisbane may have found a simple way of detecting the early stages of cancer.
  • The method is inexpensive, takes 10 minutes, and can work for all types of cancer.
  • The test uses gold particles to detect cancerous DNA.

According to Nature, researchers at the University of Brisbane may have developed a simple test that’s able to detect the early stages of cancer.

Not only that but the method is inexpensive, takes a mere 10 minutes, and works for all types of cancer — and the central component used for identifying cancer cells is gold particles.

If energy can’t be created, where did it come from in the first place?

Posted by in categories: cosmology, education, quantum physics

We’re taught at school that energy can’t be created, merely converted from one form to another. But at the birth of the Universe – that is, everything – the energy needed for the Big Bang must have come from somewhere. Many cosmologists think its origin lies in so-called quantum uncertainty, which is known to allow energy to emerge literally from nowhere. What isn’t clear, however, is why this cosmic energy persisted long enough to drive the Big Bang.

Author Vernor Vinge: Proposing a singular view of technology’s future

Posted by in categories: robotics/AI, singularity

When the Technological Singularity arrives, you can’t even imagine what the future will hold afterwards. Just ask author Vernor Vinge.

A five-time Hugo Award-winning author (among various other awards and accolades), Vernor Vinge has been writing and speculating about AI and intelligence amplification for over half a century. As part of his storied career, an interesting anecdote concerns a rejection letter he received from legendary science fiction editor and publisher John W. Campbell, Jr.

Early in his career, Vinge had proposed a story about a human being with amplified intelligence and (as Vinge relates in his short story collection) Campbell wrote him back with the comment, “Sorry — you can’t write this story. Neither can anyone else.” Jump forward a few decades, and Vinge delivered a paper to NASA entitled The Coming Technological Singularity in which he foresaw a moment when artificial intelligence will develop exponentially until it reached a point that surpasses humanity’s ability to comprehend. It is intelligence so far superior that we can’t even imagine what it would be like. And then what?

Lasers help keep CubeSats on target to handle large data downlinks

Posted by in category: satellites

An MIT team is working on a new aiming system that will allow CubeSats to use lasers for high-bandwidth communications with Earth. The new laser-pointing platform uses a second directional beam to keep the primary data beam on focus, allowing the CubeSat to transmit large amounts of data without the need for heavy antennae or wasting propellant.
