4 Charts That Show Why AI Progress Is Unlikely to Slow Down

Posted by in categories: business, education, law, robotics/AI

In the last ten years, AI systems have developed at rapid speed. From the breakthrough of besting a legendary player at the complex game Go in 2016, AI is now able to recognize images and speech better than humans, and pass tests including business school exams and Amazon coding interview questions.

Last week, during a U.S. Senate Judiciary Committee hearing about regulating AI, Senator Richard Blumenthal of Connecticut described the reaction of his constituents to recent advances in AI. “The word that has been used repeatedly is scary.”

The Subcommittee on Privacy, Technology, and the Law overseeing the meeting heard testimonies from three expert witnesses, who stressed the pace of progress in AI. One of those witnesses, Dario Amodei, CEO of prominent AI company Anthropic, said that “the single most important thing to understand about AI is how fast it is moving.”

Neuroscientists show adversities permanently change our brains

Posted by in category: neuroscience

Neuroscientists at Radboud University show that adversities permanently change the functioning of the brain. Furthermore, an aberrant reaction of the brain to adversities is related to anxiety symptoms. This may have predictive value for the development of psychiatric disorders.

Your brain is shaped by the things you experience. That sounds logical, but can you really measure that? And what can you do with it? Neuroscientists at Radboud University investigated the influence of adversities in life on patterns in the brain. They found remarkable associations that may have predictive value for the development of psychiatric disorders.

The researchers conducted their study on approximately 170 people—a special group, because all kinds of data have been collected from them during their lifetime. For this study, the scientists specifically focused on adversities: factors or events that are known to have a negative effect on development. Consider, for example, the mother’s smoking during pregnancy, complications during childbirth, abuse, or a major accident.

Diamond’s Downfall: The Quantum World’s Next Top Material

Posted by in categories: materials, quantum physics

Diamond has long been the preferred material for quantum sensing, but its size limits its applications. Recent research highlights hBN’s potential as a replacement, especially after TMOS researchers developed methods to stabilize its atomic defects and study its charge states, opening doors for its integration into devices where diamond can’t fit.

Diamond has long held the crown in the realm of quantum sensing, thanks to its coherent nitrogen-vacancy centers, adjustable spin, magnetic field sensitivity, and capability to operate at room temperature. With such a suitable material so easy to fabricate and scale, there’s been little interest in exploring diamond alternatives.

However, this titan of the quantum domain has a vulnerability. It’s simply too large. Much like how an NFL linebacker isn’t the top pick for a jockey in the Kentucky Derby, diamond falls short when delving into quantum sensors and data processing. When diamonds get too small, the super-stable defect it’s renowned for begins to crumble. There is a limit at which a diamond becomes useless.

Meet Jasmin Moghbeli, a Marine helicopter pilot and mom of twins who is leading a crew to the space station

Posted by in categories: engineering, space travel

The SpaceX Crew-7 flight will take an international team of four to the space station. Moghbeli will be the only American abroad, and is leading the mission.

The daughter of Iranian political refugees, Moghbeli went to astronaut camp as a teenager and got a degree at MIT. She played three sports, including basketball, and with space in mind studied aeronautical engineering.

She later had a gutsy career as a Marine attack helicopter pilot, serving in more than 150 combat missions – part family tradition, part service to her country and part in service to her space dreams.

Brain Gains: Scientists Discover How To Replicate the Cognitive Benefits of Exercise

Posted by in categories: biotech/medical, life extension, neuroscience

An injection of a specific blood factor can replicate exercise’s brain benefits, offering potential treatments for age-related cognitive decline.

Pre-clinical trials by University of Queensland scientists have found that an injection of a specific blood factor can replicate the benefits of exercise in the brain.

Dr. Odette Leiter and Dr. Tara Walker from UQ’s Queensland Brain Institute led a team that discovered platelets, the tiny blood cells critical for blood clotting, secrete a protein that rejuvenates neurons in aged mice in a similar way to physical exercise.

You can now train ChatGPT on your own documents via API

Posted by in categories: internet, robotics/AI

On Tuesday, OpenAI announced fine-tuning for GPT-3.5 Turbo—the AI model that powers the free version of ChatGPT—through its API. It allows training the model with custom data, such as company documents or project documentation. OpenAI claims that a fine-tuned model can perform as well as GPT-4 with lower cost in certain scenarios.

So basically, fine-tuning teaches GPT-3.5 Turbo about custom content, such as project documentation or any other written reference. That can come in handy if you want to build an AI assistant based on GPT-3.5 that is intimately familiar with your product or service but lacks knowledge of it in its training data (which, as a reminder, was scraped off the web before September 2021).
