You might be keenly interested to know that this eagerness to produce responses is something tuned into AI. The AI maker has made various computational adjustments to get the AI to press itself to respond. Why so? Because people want answers. If they aren’t getting answers from the AI, they will go someplace else. That’s not good for the AI maker since they are courting views.

There is a ton of research taking place about AI hallucinations. It is one of the most pressing AI issues of our time.

AI hallucinations are considered a scourge on the future of generative AI and LLMs. Sadly, the state-of-the-art AI still has them, for example, see my analysis of OpenAI’s most advanced ChatGPT or new model o1 that still indeed emits AI hallucinations at the link here. They are like the energy bunny and seem to just keep running.

OpenAI just unveiled a new subscription tier called ChatGPT Pro. Users can pay $200 a month for almost unlimited access to ChatGPT’s tools, and an exclusive new AI model.

“This is a highly engineered design, but the fundamental concepts are fairly simple,” said Dr. Jie Yin. “And with only a single actuation input, our robot can navigate a complex vertical environment.”

What influence can marine life have on robotics? This is what a recent study published in Science Advances hopes to address as a team of researchers from the University of Virginia and North Carolina State University have developed the fastest swimming soft robot by taking cues from manta ray fins. This study holds the potential to help researchers, engineers, and scientists develop faster and more efficient swimming soft robots that can be used for a variety of purposes worldwide.

This study builds on a 2022 study conducted by this same team of researchers that explored swimming soft robots that exhibited butterfly strokes, achieving a then-record of 3.74 body lengths per second, along with demonstrating high power efficiency, low energy use, and high maneuverability. For this new study, the researchers developed fins used by manta rays with the goal of achieving greater results than before. The fins are flexible when not in use but become rigid when the researchers pumped air into the silicone body that encompasses the soft robot.

The fastest animals are neither the largest, nor the smallest, but rather intermediately sized, though the mechanism for this is unknown. This study built predictive musculoskeletal simulations, scaled in mass from the size of a mouse to an elephant to understand the underlying mechanisms.

You deserve an explanation, so please don’t skip this 1-minute read. It’s Friday, December 6. Our fundraiser will soon be over, but we’re still short of our goal. If you’ve lost count of the number of times you’ve visited Wikipedia this year, we hope that means it’s given you at least $2.75 worth of knowledge. If everyone who finds Wikipedia useful gave just $2.75, we’d hit our goal in a few hours.

The internet we were promised—a place of free, collaborative, and accessible knowledge —is under constant threat. On Wikipedia, volunteers work together to create and verify the pages you rely on, supported by tools that undo vandalism within minutes, ensuring the information you seek is trustworthy.

Just 2% of our readers donate, so if you have given in the past and Wikipedia still provides you with $2.75 worth of knowledge, donate today. If you are undecided, remember any contribution helps. Thank you.

Astronomers have unveiled the most detailed map of the gravitational wave background to date, using pulsar timing arrays and the extraordinary sensitivity of the MeerKAT radio telescope. In my new co-author paper, we find potential tantalising hints of a “hot spot” in the gravitational wave map.

Researchers have used a mouse model to show that infections in the intestine can change the composition of bile, a fluid that is generated in the liver and is crucial to digestion. Bile aids in the absorption of fat and contributes to defense against infections. This study has suggested that intestinal infections can alter microbes in the gastrointestinal tract, or the microbiome, and modify the immune system. Although the work was conducted in mice, the researchers suggested that their conclusions also apply to humans. The findings have been reported in Nature Microbiology.

“The changes we detected in the composition of bile with infection are beneficial for the intestine to clear infection,” said corresponding study author Matthew Waldor, MD, PhD, of Brigham and Women’s Hospital. “Our findings reveal the intricate and dynamic nature of bile composition, shedding new light on the liver’s critical role in defending the intestine from infection. These insights enhance our understanding of the liver’s broader functions in regulating physiological stability and metabolic processes.”
