Could a new law of physics support the idea we’re living in a computer simulation?

Posted by in categories: computing, Elon Musk, physics

A University of Portsmouth physicist has explored whether a new law of physics could support the much-debated theory that we are simply characters in an advanced virtual world.

The simulated hypothesis proposes that what humans experience is actually an artificial reality, much like a computer simulation, in which they themselves are constructs.

The theory is popular among a number of well-known figures including Elon Musk, and within a branch of science known as information , which suggests is fundamentally made up of bits of information.

Google DeepMind Researchers Introduce Promptbreeder: A Self-Referential and Self-Improving AI System that can Automatically Evolve Effective Domain-Specific Prompts in a Given Domain

Posted by in categories: information science, robotics/AI

Large Language Models (LLMs) have gained a lot of attention for their human-imitating properties. These models are capable of answering questions, generating content, summarizing long textual paragraphs, and whatnot. Prompts are essential for improving the performance of LLMs like GPT-3.5 and GPT-4. The way that prompts are created can have a big impact on an LLM’s abilities in a variety of areas, including reasoning, multimodal processing, tool use, and more. These techniques, which researchers designed, have shown promise in tasks like model distillation and agent behavior simulation.

The manual engineering of prompt approaches raises the question of whether this procedure can be automated. By producing a set of prompts based on input-output instances from a dataset, Automatic Prompt Engineer (APE) made an attempt to address this, but APE had diminishing returns in terms of prompt quality. Researchers have suggested a method based on a diversity-maintaining evolutionary algorithm for self-referential self-improvement of prompts for LLMs to overcome decreasing returns in prompt creation.

LLMs can alter their prompts to improve their capabilities, just as a neural network can change its weight matrix to improve performance. According to this comparison, LLMs may be created to enhance both their own capabilities and the processes by which they enhance them, thereby enabling Artificial Intelligence to continue improving indefinitely. In response to these ideas, a team of researchers from Google DeepMind has introduced PromptBreeder (PB) in recent research, which is a technique for LLMs to better themselves in a self-referential manner.

Common Plastic Additive Linked to Autism And ADHD, Scientists Discover

Posted by in categories: biotech/medical, chemistry, food, health, neuroscience

The number of kids being diagnosed with autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) has risen sharply in recent decades, and a new study points to the common plastic additive bisphenol A (BPA) as a potential reason why.

BPA is used in a lot of plastics and plastic production processes, and can also be found inside food and drink cans. However, previous research has also linked it to health issues involving hormone disruption, including breast cancer and infertility.

In this new study, researchers from Rowan University and Rutgers University in the US looked at three groups of children: 66 with autism, 46 with ADHD, and 37 neurotypical kids. In particular, they analyzed the process of glucuronidation, a chemical process the body uses to clear out toxins within the blood through urine.

Researchers identify link between gut bacteria and pre-clinical autoimmunity and aging in rheumatoid arthritis

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

While the bacteria in the intestine are helpful for digesting food and fighting infections, they have long been suspected to play an essential role in triggering rheumatoid arthritis. This chronic inflammatory disorder affects the joints.

Mayo Clinic researchers have discovered a link between an abundance of specific gut bacteria and the triggering of an immune response against a person’s tissue. They also found that this happens even before the clinical symptoms of rheumatoid arthritis appear. They published their findings from the study in Science Advances.

“As we age, our gut bacteria and their byproducts change, which impacts our ,” says senior author Veena Taneja, Ph.D., a Mayo Clinic immunologist. There is a known link between imbalances in gut bacteria, aging, and rheumatoid arthritis, but it is challenging to prove this connection in humans. “This research sheds light on the complex relationship between gut microbiota and rheumatoid arthritis.”

Adding spider DNA to silkworms creates silk stronger than Kevlar

Posted by in categories: biotech/medical, food

Spiders are incredibly hard to cultivate — let alone farm.

Spider silk, a natural polymeric fiber, breaks this rule. It is somehow both strong and tough. No surprise, then, that spider silk is a source of much study.

The problem, though, is that spiders are incredibly hard to cultivate — let alone farm. If you put them together, they will attack and kill each other until only one or a few survive. If you put 100 spiders in an enclosed space, they will go about an aggressive, arachnocidal Hunger Games. You need to give each its own space and boundaries, and a spider hotel is hard and costly. Silkworms, on the other hand, are peaceful and productive. They’ll hang around all day to make the silk that has been used in textiles for centuries. But silkworm silk is fragile. It has very limited use.

Promptbreeder: Self-Referential Self-Improvement Via Prompt Evolution (Paper Explained)

Posted by in categories: engineering, evolution, information science

#evolution.

Promptbreeder is a self-improving self-referential system for automated prompt engineering. Give it a task description and a dataset, and it will automatically come up with appropriate prompts for the task. This is achieved by an evolutionary algorithm where not only the prompts, but also the mutation-prompts are improved over time in a population-based, diversity-focused approach.
