Consciousness in the machine

Posted by in categories: biological, robotics/AI

Earlier this year, Google fired Blake Lemoine, for claiming that the company’s chatbot was a self aware person. While the claim was derided, the belief that one day AI will become conscious is widespread and, according to a recent survey, held by 79% of experts. But many claim this is a fundamental error. While machines are becoming ever more capable and intelligent we still have no idea how a machine could create consciousness nor are neuroscientists able to provide an explanation for how the human brain does so.

Should we accept that consciousness arises in biological beings and that AI just isn’t made of the ‘right stuff’? Or, is it possible that a computer that observes, interacts, and represents its own internal state to itself might also give rise to consciousness? Then again, is the puzzle deeper still on the grounds that we have no means of determining whether an intelligent machine, an organism or even a person other than ourselves is conscious or not?

Legendary anti-reality theorist Donald Hoffman, fearless computer scientist and philosopher Bernardo Kastrup and distinguished AI ethicist and philosopher Susan Schneider lock horns over the possibility of AI consciousness. Theories of Everything’s Curt Jaimungal hosts.

Quantum tunneling to boost memory consolidation in AI

Posted by in categories: biological, chemistry, neuroscience, quantum physics, robotics/AI

Artificial intelligence and machine learning have made tremendous progress in the past few years including the recent launch of ChatGPT and art generators, but one thing that is still outstanding is an energy-efficient way to generate and store long-and short-term memories at a form factor that is comparable to a human brain. A team of researchers in the McKelvey School of Engineering at Washington University in St. Louis has developed an energy-efficient way to consolidate long-term memories on a tiny chip.

Shantanu Chakrabartty, the Clifford W. Murphy Professor in the Preston M. Green Department of Electrical & Systems Engineering, and members of his lab developed a relatively simple device that mimics the dynamics of the brain’s synapses, connections between that allows signals to pass information. The artificial synapses used in many modern AI systems are relatively simple, whereas biological synapses can potentially store complex memories due to an exquisite interplay between different chemical pathways.

Chakrabartty’s group showed that their artificial synapse could also mimic some of these dynamics that can allow AI systems to continuously learn new tasks without forgetting how to perform old tasks. Results of the research were published Jan. 13 in Frontiers in Neuroscience.

Recovering “Hidden Knowledge” — How an Asthma Medication Could Restore Memories

Posted by in categories: biotech/medical, genetics

Students often sacrifice sleep to study for exams, but lack of sleep can negatively impact memory. Now, University of Groningen neuroscientist Robbert Havekes has found that sleep deprivation hinders recall, not retention of information. Havekes and his team used optogenetics and the drug roflumilast to make “hidden knowledge” obtained while sleep-deprived accessible again days later. Their findings were recently published in the journal Current Biology.

Havekes, associate professor of Neuroscience of Memory and Sleep at the University of Groningen, the Netherlands, and his team have extensively studied how sleep deprivation affects memory processes. “We previously focused on finding ways to support memory processes during a sleep deprivation episode”, says Havekes.

However, in his latest study, his team examined whether amnesia as a result of sleep deprivation was a direct result of information loss, or merely caused by difficulties retrieving information.

Microsoft will let companies create their own custom versions of ChatGPT, source says

Posted by in categories: internet, robotics/AI

After six years of peace, the two tech giants are on course to butt heads again over the future of artificial intelligence.

Microsoft is about to go head-to-head with Google in a battle for the future of search. At a press event later today, Microsoft is widely expected to detail plans to bring OpenAI’s ChatGPT chatbot to its Bing search engine. Google has already tried to preempt the news, making a rushed announcement yesterday to introduce Bard, its rival to ChatGPT, and promising more details on its AI future in a press event on Wednesday.

The announcements put the two tech behemoths, known for their previous skirmishes with each other, on a collision course as they compete to define the next generation of search.

KAUST startup Lihytech raises $6 Million for lithium extraction from seawater

Posted by in categories: finance, sustainability, transportation

Saudi Arabian mining company Ma’aden, together with the King Abdullah University of Science and Technology (KAUST) Innovation Ventures Fund, are investing $6 million USD into Lithium Infinity (Lihytech). The KAUST startup’s battery-grade lithium will be a key component in driving the Kingdom of Saudi Arabia’s commitment to developing the entire value chain of electric vehicles (EVs).

Lihytech has patented a membrane-based lithium extraction technology developed by Professor Zhiping Lai at KAUST. The innovative technology can extract the alkali metal from sources such as seawater, brine, red mud and more. Based on KAUST research, the startup was funded through the KAUST Near Term Grand Challenge, a research translation program, and the technology is being developed on the campus.

This investment will take the technology from lab to commercial pilot scale. Ma’aden is leading the investment with $4 million and KAUST Innovation Ventures is investing $2 million. The University’s venture capital arm, KAUST Innovation Ventures, supports deep tech startups that look to offer solutions to pressing scientific and technological challenges, such as lithium extraction. Lihytech will use the infusion of capital to build a pilot facility at KAUST to extract lithium from the Red Sea and other in-Kingdom resources.
