New research hints at a few ways fatty foods affect cells in the brain, a finding that could help explain the link between a high-fat diet and impaired memory – especially as we age.

The Ohio State University study in cell cultures found the omega-3 fatty acid DHA may help protect the brain from an unhealthy diet’s effects by curbing fat-induced inflammation at the cellular source.

Separate experiments using brain tissue from aging mice showed a high-fat diet may lead specific brain cells to overdo cell-signaling management in a way that interferes with the creation of new memories.

Augmented reality (AR) technology has long fascinated both the scientific community and the general public, remaining a staple of modern science fiction for decades.

In the pursuit of advanced AR assistants—ones that can guide people through intricate surgeries or everyday food preparation, for example—a research team from NYU Tandon School of Engineering has introduced Augmented Reality Guidance and User-Modeling System, or ARGUS.

An interactive visual analytics tool, ARGUS is engineered to support the development of intelligent AR assistants that can run on devices like Microsoft HoloLens 2 or MagicLeap. It enables developers to collect and analyze data, model how people perform tasks, and find and fix problems in the AR assistants they are building.

The animal looked and barked like a dog—albeit one with long, pointed, foxlike ears—but it also climbed bushes, a behavior more typical of the local Pampas fox, and it refused common dog food, preferring to eat rats.

Caretakers began to wonder if it might be a hybrid—a mixture of domestic dog and some local wild canid. They contacted geneticists Thales Renato Ochotorena de Freitas from the Universidade Federal do Rio Grande do Sul and Rafael Kretschmer from the Universidade Federal de Pelotas who, last month, published a study confirming the animal was the world’s first documented fox-dog. The finding excited and intrigued experts in animal genetics.

“What a strange hybrid beast!” wrote Roland Kays, a biologist with North Carolina State University and the North Carolina Museum of Natural Sciences, on X (formerly Twitter), alongside a photo of the creature and link to the study.

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.

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.

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.

New book re-examines textile workers’ uprising against the use of technology to erase jobs centuries ago in light of similar problems stemming from AI.

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.

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.
