Algorithm allows farmers to monitor crops in real time

Posted by in categories: food, information science

Farmers across the United States will be able to monitor their crops in real time, thanks to a novel algorithm from researchers in South Dakota State University’s Geospatial Sciences Center of Excellence.

Two years ago, Yu Shen, research assistant in the GSCE, and Xiaoyang Zhang, professor in the Department of Geography and Geospatial Sciences and co-director at the GSCE, began investigating if it would be possible to make crop monitoring more efficient.

“Previously, crop progress was monitored by visually looking at the plants,” Shen explained.

Coke’s latest mystery flavor is here. It’s created by AI

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

For about a year and a half, Coca-Cola has experimented with limited-edition beverages that have mystery tastes — most of them with vague, futuristic concepts and undisclosed flavors.

The latest one, Coca-Cola Y3000, fits the bill. The one distinction: It’s supposed to taste like the future. Fittingly, the soft-drink giant used artificial intelligence to help determine the flavor and packaging.

It’s important for Coca-Cola to keep customers — particularly younger ones — excited about Coke, its more-than-a-century-old signature product. In recent years, health-conscious consumers have shied away from sugary beverages, making it trickier for soda sellers to market their legacy brands. Coca-Cola has used its Creations platform, responsible for limited-edition flavors like Y3000, to try to make the brand resonate with younger consumers.

Scientists use video games to measure the eye-brain-body connection

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

Video games could give ophthalmologists an easy window not into the soul, but into eye health and the eye-brain-body connection — the three-way reciprocal communication that influences our actions.

“Infusing science into games is like sneaking broccoli into ice cream,” said Khizer Khaderi, MD, a clinical associate professor of ophthalmology. “It removes the resistance to do something that may not be viewed as fun, such as eating vegetables.” Or in this case, evaluating your vision health.

In a Stanford Medicine-led study, researchers employed video games to evaluate participants’ field of vision and visual stamina, their ability to distinguish contrast, and other factors that can indicate common eye diseases.

Effects of electromagnetic fields exposure on the antioxidant defense system

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

If you want to read a long and complex article on EMF and oxidative stress, here’s one. And when I did a Google search on my Pixel 6 that has generative results, the result said it affected the blood brain barrier but I think it combined several websites as a source and summarized them. I’ll post a screenshot.

Free radicals are reactive molecules produced during the conversion of foods into energy through oxygen. The formation of free radicals is an oxidation reaction that occurs on an oxygen basis. [27]. Since oxygen is essential for survival, the formation of free radicals cannot be avoided. However, factors including ionizing and non-ionizing radiation alter the transcription and translation of genes such as JUN, HSP 70 and MYC, via the epidermal growth factor receptor EGFR-ras, leading to the generation of ROS [28,29] and resulting in the overproduction of ROS in tissues [30].

The Fenton reaction is a catalytic process that converts hydrogen peroxide, a product of mitochondrial oxidative respiration, into a highly toxic hydroxyl free radical. Some studies have suggested that EMF is another mechanism through the Fenton reaction, suggesting that it promotes free radical activity in cells [31,32]. Although some researchers have reported that ROS perform beneficial function, a high degree of ROS production may cause cellular damage, resulting in a range of diseases. These radicals react with various biomolecules, including DNA ( Fig. 1 ). Namely, the energy of free radicals is not enough, and for this reason they behave like robbers who seize energy from other cells and rob a person to satisfy themselves [33]. Many studies have suggested that EMF may trigger the formation of reactive oxygen species in exposed cells in vitro [34,35,36,37] and in vivo [7, 31,38]. The initial stage of the ROS production in the presence of RF is controlled by the NADPH oxidase enzyme located in the plasma membrane. Consequently, ROS activate matrix metalloproteases, thereby initiating intracellular signaling cascades to warn the nucleus of the presence of external stimulation. These changes in transcription and protein expression are observed after RF exposure [39]. Kazemi et al. investigated the effect of exposure to 900-MHz on the induction of oxidative stress and the level of intracellular ROS in human mononuclear cells. Excessive elevation in ROS levels is an important cause of oxidative damage in lipids and proteins and nucleic acids. It therefore causes changes in enzyme activity and gene expression, eventually leading to various diseases, including sleep disorder, arthrosclerosis, loss of appetite, diabetes, dizziness, rheumatoid arthritis, cardiovascular disease, nausea and stroke [40,41,42]. In addition, degradation of the pro-oxidant-antioxidant balance due to an uncontrolled increase in ROS may also result in lipid peroxidation. Lipid peroxidation is the process in which cell membranes are rapidly destroyed due to the oxidation of components of phospholipids containing unsaturated fatty acids. By continuing this reaction, lipid peroxides (-C0, H) accumulate in the membrane, and transform polyunsaturated fatty acids into biologically active substances [43]. Consequently, lipid peroxidation leads to significant damage in the cells, such as disturbances in membrane transport, structural changes, cell membrane fluidity, damage to protein receptors in membrane structures, and changes in the activity of cell membrane enzymes [44]. Hoyto et al. demonstrated significant induction of lipid peroxidation after exposure to EMF in the mouse SH-SY5Y cell and L929 fibroblast cells [45]. Epidemiological studies have also suggested that oxidative damage to lipids in blood vessel walls may be a significant contributor to the development of atherosclerosis [46,47,48].

Researchers identify the link between memory and appetite in the human brain to explain obesity

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

Disrupted connections between memory and appetite regulating brain circuits are directly proportional to body mass index (BMI), notably in patients who suffer from disordered or overeating that can lead to obesity, such as binge eating disorder (BED), according to new research from the Perelman School of Medicine at the University of Pennsylvania. Published today in Nature, the research notes that individuals who are obese have impaired connections between the dorsolateral hippocampus (dlHPC) and the lateral hypothalamus (LH), which may impact their ability to control or regulate emotional responses when anticipating rewarding meals or treats.

“These findings underscore that some individual’s brains can be fundamentally different in regions that increase the risk for obesity,” senior author, Casey Halpern, MD, an associate professor of Neurosurgery and Chief of Stereotactic and Functional Neurosurgery at Penn Medicine and the Corporal Michael J. Crescenz Veterans Affairs Medical Center. “Conditions like disordered eating and obesity are a lot more complicated than simply managing self-control and eating healthier. What these individuals need is not more willpower, but the therapeutic equivalent of an electrician that can make right these connections inside their brain.”

The dlHPC is located in the region of the brain that processes memory, and the LH is in the region of the brain that is responsible for keeping the body in a stable state, called homeostasis. Previous research has found an association with loss of function in the human hippocampus in individuals with obesity and related disordered eating, like BED. However, outside of imaging techniques such as magnetic resonance imaging (MRI), the role of the hippocampus has been difficult to study in humans with obesity and related eating disorders.

Gut Microbiome Flaws Linked to Allergies from Food to Eczema

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

A study has linked the development in kids of any of food allergy, asthma, eczema and rhinitis to a common factor – an unbalanced gut microbiome.

Researchers have long been intrigued by the gut microbiome in the development of allergic diseases. But this Canadian study is unique in identifying a common origin in infancy across the four separate allergic diseases. As well, it explored the composition of gut bacteria in children before and following allergic sensitization.

As each allergic disease has a separate list of symptoms, they are usually studied on their own. “But when you look at what is going wrong at a cellular level, they actually have a lot in common,” notes Dr. Charisse Petersen, co-senior author and a researcher at BC Children’s Hospital Research Institute and BC Children’s Hospital.
