Put a robot in a tightly-controlled environment and it can quickly surpass human performance at complex tasks, from building cars to playing table tennis. But throw these machines a curve ball and they’re in trouble—just check out this compilation of some of the world’s most advanced robots coming unstuck in the face of notoriously challenging obstacles like sand, steps, and doorways.

The reason robots tend to be so fragile is that the algorithms that control them are often manually designed. If they encounter a situation the designer didn’t think of, which is almost inevitable in the chaotic real world, then they simply don’t have the tools to react.

Rapid advances in AI have provided a potential workaround by letting robots learn how to carry out tasks instead of relying on hand-coded instructions. A particularly promising approach is deep reinforcement learning, where the robot interacts with its environment through a process of trial-and-error and is rewarded for carrying out the correct actions. Over many repetitions it can use this feedback to learn how to accomplish the task at hand.

Elon Musk has been a vocal critic of artificial intelligence, calling it an “existential threat to humanity”. He is wrong, right?


Musk is heavily invested in AI research himself through his OpenAI and NeuroLink ventures, and believes that the only safe road to AI involves planning, oversight & regulation. He recently summarized this, saying:

“My recommendation for the longest time has been consistent. I think we ought to have a government committee that starts off with insight, gaining insight… Then, based on that insight, comes up with rules in consultation with industry that give the highest probability for a safe advent of AI.”

Across dozens of media appearances, Musk’s message about AI has indeed been remarkably consistent. He says it’s dangerous, and says it needs regulation, or else “AI could turn humans into an endangered species”.

A team of researchers has developed a flexible, rechargeable silver oxide-zinc battery with a five to 10 times greater areal energy density than state of the art. The battery also is easier to manufacture; while most flexible batteries need to be manufactured in sterile conditions, under vacuum, this one can be screen printed in normal lab conditions. The device can be used in flexible, stretchable electronics for wearables as well as soft robotics.

The team, made up of researchers at the University of California San Diego and California-based company ZPower, details their findings in the Dec. 7 issue of the journal Joule.

“Our batteries can be designed around electronics, instead of electronics needed to be designed around batteries,” said Lu Yin, one of the paper’s co-first authors and a Ph.D. student in the research group of UC San Diego’s nanoengineering Professor Joseph Wang.

Being able to see, move, and exercise independently is something most of us take for granted. [Thomas Panek] was an avid runner before losing his sight due to a genetic condition, and had to rely on other humans and guide dogs to run again. After challenging attendants at a Google hackathon, Project Guideline was established to give blind runners (or walkers) independence from a cane, dog or another human, while exercising outdoors. Using a smartphone with line following AI software, and bone conduction headphones, users can be guided along a path with a line painted on it. You need to watch the video below to get a taste of just how incredible it is for the users.

Getting a wheeled robot to follow a line is relatively simple, but a running human is by no means a stable sensor platform. At the previously mentioned hackathon, developers put together a rough proof of concept with a smartphone, using its camera to recognize a painted line on the ground and provide left/right audio cues. As the project developed, the smartphone was attached to a waist belt and bone conduction headphones were used, which don’t affect audio situational awareness as much as normal headphones.

The shaking and side to side movement of running, and varying light conditions and visual obstructions in the outdoors made the problem more difficult to solve, but within a year the developers had completed successful running tests with [Thomas] on a well-lit indoor track and an outdoor pedestrian path with a temporary line. For the first time in 25 years, [Thomas] was able to run independently.

The idea that mass extinctions allow many new types of species to evolve is a central concept in evolution, but a new study using artificial intelligence to examine the fossil record finds this is rarely true, and there must be another explanation.

Charles Darwin’s landmark opus, On the Origin of the Species, ends with a beautiful summary of his theory of evolution, “There is a grandeur in this view of life, with its several powers, having been originally breathed into a few forms or into one; and that, whilst this planet has gone cycling on according to the fixed law of gravity, from so simple a beginning endless forms most beautiful and most wonderful have been, and are being, evolved.”

In fact, scientists now know that most species that have ever existed are extinct. This extinction of species has on the whole been roughly balanced by the origination of new ones over Earth’s history, with a few major temporary imbalances scientists call mass extinction events. Scientists have long believed that mass extinctions create productive periods of species evolution, or “radiations,” a model called “creative destruction.” A new study led by scientists affiliated with the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology used machine learning to examine the co-occurrence of fossil species and found that radiations and extinctions are rarely connected, and thus mass extinctions likely rarely cause radiations of a comparable scale.

I think it has its own niche. 😃


Whenever an artificial intelligence (AI) does something well, we’re simultaneously impressed as we are worried. AlphaGO is a great example of this: a machine learning system that is better than any human at one of the world’s most complex games. Or what about Google’s neural networks that are able to create their own AIs autonomously?

Like we said – seriously impressive, but a little unnerving perhaps. That is probably why we feel such glee when an AI goes a little awry. Remember that Chatbot created by Microsoft, the one that was designed to learn how to converse with people based on what it read on Twitter? Rather predictably, it quickly became a racist, foul-mouthed bigot.

Now, a new AI has appeared on the wilderness of the Web, and it goes by the name InspiroBot. As you might expect, it designs “Inspirational Posters” for you – you know, the “Shoot for the Moon. If you miss, you’ll land among the stars”-type quotes in an aesthetically pleasing font and plastered onto a calming, pretty background image of deep space or flowers or the sunrise or something.

For years, futurists have attempted to predict when, in the future, we will finally achieve the technological singularity’’ — a technological breakthrough so profound, it changes the course of humanity. Specifically, futurists have been talking about the moment when super-human artificial intelligence becomes reality. Or — to put it simply — when computers become smarter than people.

However, at Centaura, we believe that the world needs to prepare for a different singularity — one that might arrive even before super-human intelligence. It’s the moment when humans have the power to slow down — and even reverse aging.

The idea of the singularity first became popular nearly thirty years ago by the science fiction writer Vernor Vinge. In his essay The Coming Technological Singularity, he famously declared, Within thirty years, we will have the technological means to create superhuman intelligence. Shortly after, the human era will be ended.

From the COVID-19 vaccine to advances in machine learning, AI, improved W-Fi and 5G, and telemedicine, experts expect a move to “patient-centric” health next year.

COVID-19 accomplished what entrepreneurs, doctors, and activists couldn’t: Designing a healthcare system that works for patients instead of providers and health insurance companies.

The industry promised to be “patient-centered” for the last decade but only the harsh demands of COVID-19 have made this a reality. As Ian McCrae, CEO of Orion Health, described it, COVID-19 is ushering in the long-overdue transformation of the healthcare system and, finally, a move to “patient-centric” health.
