From veneers to abrasive toothpastes, a perfect smile can hide cavities and cause other problems.

Your teeth probably don't look like a movie star's, and that might be a good thing. Breakthroughs, discoveries, and DIY tips sent six days a week. However, in recent years, critics have pointed out that one thing can immediately dispel historical accuracy: actors' blindingly white, perfect teeth.

While systems designed for solving planning tasks vastly outperform Large Language Models (LLMs) in this domain, they usually discard the rich semantic information embedded within task descriptions. In contrast, LLMs possess parametrised knowledge across a wide range of topics, enabling them to leverage the natural language descriptions of planning tasks in their solutions. However, current research in this direction faces challenges in generating correct and executable plans. Furthermore, these approaches depend on the LLM to output solutions in an intermediate language, which must be translated into the representation language of the planning task. We introduce a novel planning method, which leverages the parametrised knowledge of LLMs by using their output as a heuristic for Hill-Climbing Search. This approach is further enhanced by prompting the LLM to generate a solution estimate to guide the search. Our method outperforms the task success rate of similar systems within a common household environment by 22 percentage points, with consistently executable plans. All actions are encoded in their original representation, demonstrating that strong results can be achieved without an intermediate language, thus eliminating the need for a translation step.

Robotic dentistry is becoming a reality. Your dentist may remind you to brush, floss and mouthwash – but what is the "right" order to do it? While all steps of oral hygiene can benefit dental health, Dr. Mike Wei, DDS, of New York City, shared with Fox News Digital that he'd recommend the below order. Starting with floss helps to remove food debris and plaque between the teeth and along the gumline, which a toothbrush "may not reach effectively," according to Wei. Dr. Ellie Phillips (not pictured) recommends using xylitol gum and mints to promote healthy salivary flow.

Large language models (LLMs) are being applied as actors for sequential decision making tasks in domains such as robotics and games, utilizing their general world knowledge and planning abilities. However, previous work does little to explore what environment state information is provided to LLM actors via language. Exhaustively describing high-dimensional states can impair performance and raise inference costs for LLM actors. Previous LLM actors avoid the issue by relying on hand-engineered, task-specific protocols to determine which features to communicate about a state and which to leave out. In this work, we propose Brief Language INputs for DEcision-making Responses (BLINDER), a method for automatically selecting concise state descriptions by learning a value function for task-conditioned state descriptions. We evaluate BLINDER on the challenging video game NetHack and a robotic manipulation task. Our method improves task success rate, reduces input size and compute costs, and generalizes between LLM actors.

Trapped in a metal cage in a corner of a 350,000 sq ft Amazon warehouse outside Boston last week a lonely yellow robot arm sorted through packages, preparing items to be shipped out to customers who demand ever-faster delivery. Soon it will be joined by others in a development that could mean the end of thousands of jobs and, Amazon argues, the creation of thousands of others. As the robot worked, a screen displayed its progress. It carefully packed a tub of protein powder, next came a box of napkin rings then … a tube of hemorrhoid cream. As 100 journalists from around the world snapped pictures, someone switched the screen to hide the cream.

Judea Pearl is chancellor's professor of computer science and statistics at UCLA and co-author of "The Book of Why: The Science of Cause and Effect" with Dana Mackenzie, a mathematics writer. This column originally appeared in the Wall Street Journal. Computer programs have reached a bewildering point in their long and unsteady journey toward artificial intelligence. They outperform people at tasks we once felt to be uniquely human, such as playing poker or recognizing faces in a crowd. Meanwhile, self-driving cars using similar technology run into pedestrians and posts and we wonder whether they can ever be trustworthy. Amid these rapid developments and nagging setbacks, one essential building block of human intelligence has eluded machines for decades: Understanding cause and effect.

Put simply, today's machine-learning programs can't tell whether a crowing rooster makes the sun rise, or the other way around. Whatever volumes of data a machine analyzes, it cannot understand what a human gets intuitively. From the time we are infants, we organize our experiences into causes and effects. The questions "Why did this happen?" Suppose, for example, that a drugstore decides to entrust its pricing to a machine learning program that we'll call Charlie.

A laboratory robot powered by artificial intelligence (AI) has discovered that a compound commonly found in toothpaste could be used to combat drug-resistant malaria parasites. Triclosan could be deployed against strains of plasmodium malaria parasites that have evolved resistance to the widely used drug pyrimethamine, according to the University of Cambridge.

A laboratory robot powered by artificial intelligence (AI) has discovered that a compound commonly found in toothpaste could be used to combat drug-resistant malaria parasites. Triclosan could be deployed against strains of plasmodium malaria parasites that have evolved resistance to the widely used drug pyrimethamine, according to the University of Cambridge. Pyrimethamine works by inhibiting a particular enzyme called DHFR and scientists have known for some time that triclosan can be employed to target another enzyme, ENR. The fast-moving AI routines of the robot "Eve", however, which formulate, test and re-evaluate hypotheses in quick succession, discovered that the common toothpaste chemical also attacks DHFR – even in parasites resistant to pyrimethamine. It has led researchers to hope that triclosan could be developed for use in a two-pronged attack on plasmodium in the liver and in the blood.
