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.
