OpenAI released its premier AI text-to-video generator, and the results are as incredible as they are concerning.
A comprehensive analysis of the top conversational artificial intelligence platforms
PALO ALTO, Calif., Feb. 14, 2024 /PRNewswire/ — In the dynamic landscape of AI-powered content generation, OpenAI stands at the forefront of Artificial General Intelligence (AGI) research. However, the primary purpose of products such as GPT-4 is to act as a productivity aid, for tasks such as coding. In addition, access to the best such models is often restricted by paywalls. These limitation have led to the growing popularity of other platforms which are primarily focused on providing Generative AI for consumers.
DUBAI, United Arab Emirates — DUBAI, United Arab Emirates (AP) — The CEO of ChatGPT-maker OpenAI said Tuesday that the dangers that keep him awake at night regarding artificial intelligence are the “very subtle societal misalignments” that could make the systems wreak havoc.
Sam Altman, speaking at the World Governments Summit in Dubai via a video call, reiterated his call for a body like the International Atomic Energy Agency to be created to oversee AI that’s likely advancing faster than the world expects.
“There’s some things in there that are easy to imagine where things really go wrong. And I’m not that interested in the killer robots walking on the street direction of things going wrong,” Altman said. “I’m much more interested in the very subtle societal misalignments where we just have these systems out in society and through no particular ill intention, things just go horribly wrong.”
University of Pennsylvania engineers have developed a new chip that uses light waves, rather than electricity, to perform the complex math essential to training AI. The chip has the potential to radically accelerate the processing speed of computers while also reducing their energy consumption.
The silicon-photonic (SiPh) chip’s design is the first to bring together Benjamin Franklin Medal Laureate and H. Nedwill Ramsey Professor Nader Engheta’s pioneering research in manipulating materials at the nanoscale to perform mathematical computations using light—the fastest possible means of communication—with the SiPh platform, which uses silicon, the cheap, abundant element used to mass-produce computer chips.
The interaction of light waves with matter represents one possible avenue for developing computers that supersede the limitations of today’s chips, which are essentially based on the same principles as chips from the earliest days of the computing revolution in the 1960s.
A new Amazon AI model, according to the researchers who built it, is exhibiting language abilities that it wasn’t trained on.
In a not-yet-peer-reviewed academic paper, the team at Amazon AGI — which stands for “artificial general intelligence,” or human-level AI — say their large language model (LLM) is exhibiting “state-of-the-art naturalness” at conversational text. Per the examples shared in the paper, the model does seem sophisticated.
As the paper indicates, the model was able to come up with all sorts of sentences that, according to criteria crafted with the help of an “expert linguist,” showed it was making the types of language leaps that are natural in human language learners but have been difficult to obtain in AI.

Researchers at the Nanyang Technical University (NTU) in Singapore are leading the way in the development of soft electronics and have now set up a high-tech laboratory where they can rapidly prototype new devices with ultrathin and stretchable electronics.
Conventional electronics products are hard and rigid since they rely on silicon as their primary substrate. These products work well at industrial scales or even for personal use products.
BUT, rigidity becomes a major hurdle when they have to be used in conjunction with the human body.
Remote surgery in orbit.
Earth-bound surgeons remotely controlled a small robot aboard the International Space Station over the weekend, conducting the first-ever such surgery in orbit—albeit on rubber bands.
The experiment, deemed a “huge success” by the participants, represents a new step in the development of space surgery, which could become necessary to treat medical emergencies during multi-year manned voyages, such as to Mars.
The technology could also be used to develop remote-control surgery techniques on Earth, to serve isolated areas.
More than 4,500 heart transplants were performed in the U.S. in 2023. While the lifesaving operation improves the quality of life and longevity for most recipients, organ rejection remains a risk, with acute rejection occurring in up to 32% of recipients within the first year.
A team of researchers from Emory University, Case Western Reserve University and the University of Pennsylvania developed artificial intelligence tools to examine cardiac biopsy images to improve the prediction of rejection, helping to ensure patients receive the best possible post-transplant treatment.
Currently, clinicians rely on histologic grading of cardiac biopsies to diagnose acute rejection. However, there are limitations to the method, which assigns International Society of Heart and Lung Transplantation (ISHLT) histologic grades corresponding to no, mild, moderate and severe rejection.
