Dopamine Might Have An Unexpected Function That Could Reshape Our Understanding Of Brain Conditions

Posted by in categories: cybercrime/malcode, food, neuroscience, sex

Dopamine seems to be having a moment in the zeitgeist. You may have read about it in the news, seen viral social media posts about “dopamine hacking,” or listened to podcasts about how to harness what this molecule is doing in your brain to improve your mood and productivity. However, recent neuroscience research suggests that popular strategies to control dopamine are based on an overly narrow view of how it functions.

Dopamine is one of the brain’s neurotransmitters — tiny molecules that act as messengers between neurons. It is known for its role in tracking your reaction to rewards such as food, sex, money, or answering a question correctly. There are many kinds of dopamine neurons located in the uppermost region of the brainstem that manufacture and release dopamine throughout the brain. Whether neuron type affects the function of the dopamine it produces has been an open question.

Recently published research reports a relationship between neuron type and dopamine function, and one type of dopamine neuron has an unexpected function that will likely reshape how scientists, clinicians, and the public understand this neurotransmitter.

Farm robots inspired by ant brains

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

With the rapid-paced rise of AI in everyday life, nothing, not even the traditional farmer, is untouched by the technology.

A survey of the latest generation of farm tools provides a taste of just how far modern farming has come.

The Ecorobotix, a seven-foot-wide GPS-assisted “table on wheels” as some have described it, is a solar battery-powered unit that roams crop fields and destroys weeds with pinpoint precision. It boasts a 95% efficiency rate, with virtually no waste.

Scientists have developed a new artificial neural network that mimics the brain structures of ants and helps robots recognize and remember routes in complex natural environments, such as cornfields. The approach could improve the performance of agricultural robots that need to move through dense and plant-filled landscapes.

Can a new Luddite rebellion rise against Big Tech? ‘We’re in a place where trouble could find us pretty quickly,’ author says

Posted by in categories: biotech/medical, cybercrime/malcode, employment, food, robotics/AI

Not all wages are bad. If you’re a doctor or nurse you can earn decent. Even a PC tech can earn around $24 an hour or more and cyber security 100k and if you are an engineer you can earn a lot. If you work in a gas station however you won’t earn much. If you are in assembly not much either. It takes skills to earn money. Plus the politicians determine the wages too, it’s not all on big tech. Some tech companies pay more than others of course but knowing AI will increase your wages. They have courses on ChatGPT online now. Even if you run a farm you earn the most money. They’re afraid of progress or I dunno what. Yes we proceed with caution but it’s not like we stop. China won’t nor Russia nor the Middle East etc and even if we’re not in conflict we’ll be left behind.

Using quantum materials as catalysts for fertilizer synthesis

Posted by in categories: food, quantum physics

Synthetic fertilizers, one the most important developments in modern agriculture, have enabled many countries to secure a stable food supply. Among them, organic ureas (or organoureas) have become prominent sources of nitrogen for crops. Since these compounds do not dissolve immediately in water, but instead are slowly decomposed by soil microorganisms, they provide a stable and controlled supply of nitrogen, which is crucial for plant growth and function.

However, traditional methods to synthesize organoureas are environmentally harmful due to their use of toxic substances, such as phosgene. Although alternative synthesis strategies have been demonstrated, these either rely on expensive and scarce noble metals or employ catalysts that cannot be reused easily.

In a recent effort to address these challenges, a research team including Honorary Professor Hideo Hosono from Tokyo Institute of Technology, Japan, has leveraged the quantum properties of bismuth selenide (Bi2Se3) to synthesize organoureas. Their study is published in Science Advances.

Palm oil alternative is better for health and environment

Posted by in categories: food, health

A new palm oil substitute called PALM-ALT has been developed by researchers at Queen Margaret University in Scotland. The plant-based ingredient is shown to be healthier, as well as 70% better for the environment than conventional palm oil and is described as “the holy grail to replace it.”

Food experts at Queen Margaret University (QMU) in Edinburgh have developed a new ingredient which has the potential to replace palm oil in bakery products. The new substitute is both healthier and more environmentally friendly than palm oil, which is currently used in a vast amount of baked goods. This could be a game-changing solution for the food industry, allowing manufacturers to satisfy increasing demand for tasty, lower fat, healthier products, whilst also reducing deforestation of the world’s rainforests.

New study disproves Leonardo da Vinci’s ‘rule of trees’

Posted by in category: food

A “rule of trees” developed by Leonardo da Vinci to describe how to draw trees has been largely adopted by science when modeling trees and how they function.

Now, scientists at Bangor University in the U.K. and the Swedish University of Agricultural Sciences (SLU) have discovered that this rule contradicts those that regulate the internal structures of .

Da Vinci’s interest in drawing led him to look at size ratios of different objects, including trees, so that he could create more accurate representations of them. To correctly represent trees, he perceived a so-called “rule of trees” which states that “all the branches of a tree at every stage of its height are equal in thickness to the trunk when put together.”

Preventing $220 Billion in Damages — Scientists Discover Potential Way To Disarm a Mysterious Family of Microbial Proteins

Posted by in categories: biotech/medical, food

Many of the bacteria that ravage crops and threaten our food supply employ a shared tactic to induce disease: they inject a cocktail of harmful proteins directly into the plant’s cells.

For 25 years, biologist Sheng-Yang He and his senior research associate Kinya Nomura have been investigating this set of molecules that plant pathogens use to cause diseases in hundreds of crops globally, from rice to apple orchards.

Now, thanks to a team effort between three collaborating research groups, they may finally have an answer to how these molecules make plants sick — and a way to disarm them.

Overeating and addiction may have roots in early human brain evolution and prosocial behaviors

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

Research led by the Department of Anthropology and School of Biomedical Sciences, Kent State University, Ohio, has investigated neuropeptide Y innervation in an area of the brain called the nucleus accumbens of various primate species, including humans. The research was focused on understanding its role in brain evolution and any implications for human health, particularly regarding addiction and eating disorders.

In a paper, “Hedonic eating, obesity, and addiction result from increased neuropeptide Y in the nucleus accumbens during human ,” published in PNAS, the researchers suggest that the combination of increased neuropeptide Y (NPY) and dopamine (DA) within the human nucleus accumbens (NAc) may have allowed for enhanced . This same configuration may have also made humans exceptionally vulnerable to eating disorders and , hinting at addictive traits having a deep evolutionary origin.

NPY plays a role in the reward system, emotional behavior and is associated with increased alcohol use, drug addiction and . The NAc brain region is central to motivation and action, exhibiting one of the highest densities of NPY in the brain and is of great interest to researchers investigating brain-related promoters of addiction.
