Sustainable Plastics from Agricultural Waste

Posted by in categories: food, sustainability

Scientists have developed a sustainable method to make high-performance plastics from agricultural leftovers, turning them into valuable materials.

In our rapidly industrialized world, the quest for sustainable materials has never been more urgent. Plastics, ubiquitous in daily life, pose significant environmental challenges, primarily due to their fossil fuel origins and problematic disposal.

Now, a study led by Jeremy Luterbacher’s team at EPFL unveils a pioneering approach to producing high-performance plastics from renewable resources.

When It Comes to Making Generative AI Food Smart, Small Language Models Are Doing the Heavy Lifting

Posted by in categories: food, health, robotics/AI

Since ChatGPT debuted in the fall of 2022, much of the interest in generative AI has centered around large language models. Large language models, or LLMs, are the giant compute-intensive computer models that are powering the chatbots and image generators that seemingly everyone is using and talking about nowadays.

While there’s no doubt that LLMs produce impressive and human-like responses to most prompts, the reality is most general-purpose LLMs suffer when it comes to deep domain knowledge around things like, say, health, nutrition, or culinary. Not that this has stopped folks from using them, with occasionally bad or even laughable results and all when we ask for a personalized nutrition plan or to make a recipe.

LLMs’ shortcomings in creating credible and trusted results around those specific domains have led to growing interest in what the AI community is calling small language models (SLMs). What are SLMs? Essentially, they are smaller and simpler language models that require less computational power and fewer lines of code, and often, they are specialized in their focus.

More Complex Than Human Genome: Unlocking the Sweet Mysteries of Sugarcane DNA

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

Scientists created a highly accurate reference genome for one of the most important modern crops and found a rare example of how genes confer disease resistance in plants. Exploring sugarcane’s genetic code could help researchers develop more resilient and productive crops, with implications for both sugar production and biofuels.

How Is Flocking Like Computing?

Posted by in categories: biological, computing, food, physics

Birds flock. Locusts swarm. Fish school. Within assemblies of organisms that seem as though they could get chaotic, order somehow emerges. The collective behaviors of animals differ in their details from one species to another, but they largely adhere to principles of collective motion that physicists have worked out over centuries. Now, using technologies that only recently became available, researchers have been able to study these patterns of behavior more closely than ever before.

In this episode, the evolutionary ecologist Iain Couzin talks with co-host Steven Strogatz about how and why animals exhibit collective behaviors, flocking as a form of biological computation, and some of the hidden fitness advantages of living as part of a self-organized group rather than as an individual. They also discuss how an improved understanding of swarming pests such as locusts could help to protect global food security.

Breaking ground in genome-editing technology

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

Genomes are the blueprints of living creatures; chromosomes and genes within all our cells encode information about life. Genome editing technology that can change these chromosomes and genes has developed rapidly. From drug development and gene therapy, improvements to crops and livestock, to creating useful microorganisms to replace petroleum, this technology has started to have a significant impact on our societies.

Professor NISHIDA Keiji (Graduate School of Science, Technology and Innovation) has developed a new genome editing technology and established a business venture based on his research findings. He is on the front lines of genome editing in both business and research.

Chickadees have unique neural ‘barcodes’ for memories of stashing away food

Posted by in categories: food, neuroscience

Black-capped chickadees have extraordinary memories that can recall the locations of thousands of morsels of food to help them survive the winter. Now scientists at Columbia’s Zuckerman Institute have discovered how the chickadees can remember so many details: they memorize each food location using brain cell activity akin to a barcode. These new findings may shed light on how the brain creates memories for the events that make up our lives.

Chilling Findings: Scientists Shed Light on How the Brain Perceives Temperature

Posted by in categories: food, neuroscience

Christian Lemon, Ph.D., an associate professor in the School of Biological Sciences at the University of Oklahoma, often thinks about temperature sensation and the brain when eating a chilled mint cookie. Now, research from his lab examining oral temperature perception has been published in The Journal of Neuroscience.

In their research, Lemon’s team investigates how cold receptors in the mouth are activated by cooling temperatures, how those signals are transmitted to the brain and how those transmissions are generated into a cooling sensation.

The dangers of AI farming.

AI could lead to new ways for people to abuse animals for financial gain. That’s why we need strong ethical guidelines.
