Urban populations face critical issues of food waste and food-borne diseases, which contribute to greenhouse emissions and environmental costs. Food spoilage remains the primary cause of such waste. Therefore, it is essential to improve the processing, transportation, and preservation of food in line with current technological advancements. Unfortunately, present monitoring processes are inefficient, expensive, and

Scientists from Radboud University have created synthetic molecules that mimic the behavior of real organic molecules. A team of researchers led by Alex Khajetoorians and Daniel Wegner have developed the ability to simulate the behavior of real molecules by using artificial molecules. This breakthrough allows properties of molecules to be tweaked in ways that were

The activation of G protein-coupled receptors (GPCRs) is responsible for relaying molecular signals in the body, which affects various bodily processes. It is estimated that around one-third of existing drugs work by controlling the activation of this protein. However, drugs that activate multiple signaling pathways rather than a specific target pathway can lead to adverse

As summer approaches, people all across America are getting ready to fire up their grills and cook everything from hot dogs to steaks. However, millions of Americans with seafood allergies cannot eat shrimp, a delicacy that many people enjoy during this season. However, researchers have developed a new method that could change that. The Journal

Chemists at the Cold Spring Harbor Laboratory (CSHL) in collaboration with K. Barry Sharpless, a two-time Nobel laureate, have developed a new chemical transformation they call phosphorus fluoride exchange (PFEx). The new technique snaps together chemical building blocks to form new molecules, leading to a vast array of complex molecules that can be explored. This

Researchers at the University of Helsinki and from the United States have found a new small molecule that can inhibit cells from producing cytokine proteins that promote inflammation. Cytokines are responsible for the onset of diseases such as rheumatoid arthritis. By inhibiting a target protein called Sec61, the researchers were able to alleviate arthritis symptoms

In 1923, Fritz Pregl was awarded the Nobel Prize in chemistry for his contributions to quantitative microanalysis, which became a crucial tool to determine the elements present in a sample or compound. This technique has been widely adopted in the field of chemistry to determine the identity and purity of a chemical. However, the long-accepted

Quantum mechanics is a complex field that is difficult to visualize. However, researchers at the University of Illinois Urbana-Champaign have developed a new illustration technique that displays quantum features in an easy-to-read diagram called a coherence map. Using this technique, the researchers were able to study the quantum mechanisms that underlay photosynthesis, the process by

Studying radioactive materials is a challenging task due to the potential health risks associated with them, as well as their high costs. Some radioisotopes can cost more than $10,000 per microgram, making them difficult to study in detail. Furthermore, some radioisotopes cannot be produced in sufficient quantities, adding to the difficulties of studying them. However,

A team of biochemical engineers from the University of California, Irvine, has developed a finite state machine (FSM) using microfluidic valves and a pneumatic circuit to create a lab-on-a-chip. The goal of automating many chemical processes currently done by hand has been sought after by mechanical and biochemical engineers for several years. By automating these

A recent study led by the University of Virginia has challenged the long-held understanding of how materials known as associative polymers function at the molecular level. The study, which has been published in the journal Physical Review Letters, has important implications for the many ways associative polymers are used in everyday life, ranging from engineering

The field of electronics has seen significant advancements in recent years, leading to the creation of smaller and more sophisticated devices such as wearable technologies, biosensors, medical implants, and soft robots. The majority of these technologies rely on stretchy materials with electronic properties. However, many of the flexible materials used in these devices are fragile

Researchers have made significant progress in developing better catalysts to convert methane into a less harmful chemical. Methane is a powerful greenhouse gas that is being released into the atmosphere at an increasing rate due to livestock farming and the melting of permafrost. The transformation of methane into a less harmful and useful chemical could

Researchers worldwide are working diligently to discover ways to combat bacteria that can resist current antibiotics to prevent a global health crisis. One potential target for the development of improved antibiotics is riboswitches, which are small RNA segments that regulate the production of proteins by bacterial cells. Riboswitches are almost exclusively found in bacteria, making

Researchers at North Carolina State University have found a new method of producing carbon dioxide capture filters using 3-D printing. The study, which was published in the journal Gels, suggests that 3-D printing could offer a faster and more versatile method of manufacturing filter designs. The research was conducted by the Wilson College of Textiles,
