No, Today’s AI Isn’t Sentient. Here’s How We Know

Posted by in categories: food, mathematics, robotics/AI, space

All sensations—hunger, feeling pain, seeing red, falling in love—are the result of physiological states that an LLM simply doesn’t have. Consequently we know that an LLM cannot have subjective experiences of those states. In other words, it cannot be sentient.

An LLM is a mathematical model coded on silicon chips. It is not an embodied being like humans. It does not have a “life” that needs to eat, drink, reproduce, experience emotion, get sick, and eventually die.

It is important to understand the profound difference between how humans generate sequences of words and how an LLM generates those same sequences. When I say “I am hungry,” I am reporting on my sensed physiological states. When an LLM generates the sequence “I am hungry,” it is simply generating the most probable completion of the sequence of words in its current prompt. It is doing exactly the same thing as when, with a different prompt, it generates “I am not hungry,” or with yet another prompt, “The moon is made of green cheese.” None of these are reports of its (nonexistent) physiological states. They are simply probabilistic completions.

How big can this be made? Enough for a household, a herd, communities, crops?

Scientists develop new geochemical ‘fingerprint’ to trace contaminants in fertilizer

Posted by in categories: chemistry, food

An international team of scientists has uncovered toxic metals in mineral phosphate fertilizers worldwide by using a new tool to identify the spread and impact of such contaminants on soil, water resources, and food supply.

The New ‘Dream Chaser’ Spacecraft Prepares to Visit the International Space Station

Posted by in categories: food, space

Sierra Space’s Dream Chaser is set to make its inaugural trip to orbit to deliver supplies to the International Space Station.

By Sarah Scoles

With its perpetually upturned pectoral fins, and blunt nose, the Dream Chaser looks more like a killer whale than a spacecraft. But unlike an orca, the Dream Chaser will soon be going to orbit: it’s set to take food and supplies to the International Space Station (ISS) later this year when it travels to space for the first time.

The State of CRISPR and Gene Editing 2024

Posted by in categories: bioengineering, biotech/medical, food

Following the landmark approval of the first CRISPR-based cell therapy in December 2023, the CRISPR community is looking ahead to the next wave of commercial successes, fueled by continued innovation in the development of new gene editing and delivery tools and technologies. Equally exciting advances are occurring in livestock editing, xenotransplantation, and many other specialties.

In The State of CRISPR and Gene Editing virtual summit, GEN proudly gathers a tantalizing line-up of luminaries from academia and industry to discuss the latest research developments, innovations, and advanced technologies that are expanding the CRISPR toolbox, delivering new therapies to patients and safeguarding our food supply.

Scientists Imaged and Mapped a Tiny Piece of Human Brain. Here’s What They Found

Posted by in categories: biotech/medical, computing, food, neuroscience

Researchers have made a digital map showing a tiny chunk of a human brain in unprecedented detail.

Based on a brain tissue sample that had been surgically removed from a person, the map represents a cubic millimeter of brain—an area about half the size of a grain of rice. But even that tiny segment is overflowing with 1.4 million gigabytes of information—containing about 57,000 cells, 230 millimeters of blood vessels and 150 million synapses, the connections between neurons.

The researchers published their findings in the journal Science on Friday. They have made the data set freely available online and provided tools for analyzing and proofreading it.

Why AI playing video games is a big deal

Posted by in categories: entertainment, food, robotics/AI, sustainability

The lab’s latest AI news is something different, though. Instead of designing a model to master a single game, DeepMind has teamed up with researchers from the University of British Columbia to develop an AI agent capable of playing a whole bunch of totally different games.

Called SIMA (scalable i nstructable m ulti-world a gent), the project also marks a shift from competitive to cooperative play as the AI operates by following human instructions.

But SIMA wasn’t created simply to help sleepy players grind out levels or farm up resources. The researchers instead hope that by better understanding how SIMA learns in these virtual playgrounds, we can make AI agents more cooperative and helpful in the real world.

Solving a Long-Standing Marine Mystery: New Insights Into Rhizobia-Diatom Symbiosis

Posted by in categories: biological, food

A groundbreaking study reveals that Rhizobia bacteria can fix nitrogen in partnership with marine diatoms, a discovery that could have significant implications for agriculture and marine ecosystems.

Nitrogen is an essential component of all living organisms. It is also the key element controlling the growth of crops on land, as well as the microscopic oceanic plants that produce half the oxygen on our planet.

Atmospheric nitrogen gas is by far the largest pool of nitrogen, but plants cannot transform it into a usable form. Instead, crop plants like soybeans, peas and alfalfa (collectively known as legumes) have acquired Rhizobial bacterial partners that “fix” atmospheric nitrogen into ammonium. This partnership makes legumes one of the most important sources of proteins in food production.

Researchers discover how Gut Muscle can be Vital for Growth, Repair and Treatments

Posted by in categories: biotech/medical, food

The findings, published in a study in Developmental Cell, reveal that intestinal smooth muscle originates in embryos and forms by the same process that is a hallmark of creating scar tissue when a wound heals.

The smooth muscle sits inside tiny finger-like projections called villi, which absorb fats—also known as lipids—from foods. Contractions of these smooth muscles squeeze absorbed dietary fats through lymphatic capillaries, called lacteals, which send the fats into the systemic blood circulation to produce energy.

Blautia Bacteria’s Crucial Role as a Gut Barrier Shield is Revealed

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

Western diets that are high in sugars, fats, and processed foods have been linked to a wide variety of health ailments. Now, researchers have determined that Western diets can also disrupt the crucial barrier in the gastrointestinal tract known as the gut mucosa. This disruption can raise an individual’s risk of inflammation and infectious disease. Scientists have also identified a gut microbe called Blautia that has an important role in shielding the gut mucosa. The findings have been reported in Nature Communications.

“Our results contribute to an increased understanding of how the intestinal bacteria and the mucus layer work together, which may eventually lead to new treatment strategies for diseases linked to the Western diet such as the inflammatory bowel disease ulcerative colitis,” said first study author Sandra Holmberg, a graduate student at Umeå University.
